Youth who are heterosexual and gay, lesbian or bisexual GLB are one of the most disenfranchised and marginalized groups in our society. Participants for this homosexuality included youth involved in treatment outcome studies with substance abusing homeless youth.

In examining the predictors of sexual health risks, survival sex emerged as the most significant. Survival sex was high among females regardless of their sexual orientation and also among gay males. Implications of these findings suggest that a greater emphasis needs to be paid heterosexual preventive interventions among this population.

One particularly disturbing consequence of being homeless is engaging in behaviors that put oneself at risk for HIV infection. Overall, the homeless homosexxuality has a disproportionately higher risk of HIV transmission Ebner and Laviage, and substance use Kipke et al.

Substance abuse has been associated as a risk factor for HIV, both in terms of drug homosexuality sexual related risk Rotheram-Borus et al. In a recent study designed to explore the differences in sexual health risks and protective factors Rew et al. This was partially supported by a homoseuxality study Solorio et al. While this could imply that gay and lesbian homeless youth are at a greater risk for STIs, there is currently little empirical evidence to show whether differences in HIV risks among heterosexual and gay, lesbian, and bisexual GLB youth exist.

Such evidence would be helpful in better understanding the needs of homosexuality youth and also to better inform intervention strategies. Thus, the purpose of this study was to bridge this gap by comparing aids HIV risks among heterosexual and GLB youth in a population of homeless youth. Findings suggest that GLB youth have greater rates of depression, more suicide attempts Fergusson et al.

Emerging aids also indicate that GLB homeless youth experience greater risks in terms of heterosexjal, substance use and abuse, rates of psychopathology, depression and suicidal ideation Cochran et al. Gender differences have homoseuality been noted by some researchers. For instance, Whitbeck and colleagues in a longitudinal study of homeless and runaway adolescents found that gay males were more likely to have symptoms of internalization when compared to heterosexual males.

Lesbian adolescents were more wids to have symptoms of post-traumatic stress disorder, suicidal ideation, suicide attempts and substance abuse when compared to aids females.

In addition, gay and heterosexual males were also more likely to have recently used marijuana homosexuality any of the other groups. These findings suggest that there are important inter-group differences among the GLB youth.

Therefore, in this study we examined differences based on gender in both heterosexual and non-heterosexual youth. Just as there may be differences based on gender, it is also important that unique factors that may exist when examining homeless youth versus sheltered youth be acknowledged. Interestingly caregiver attributes of warmth and support were also associated with having more sexual partners in the last 30 days. This supports findings of earlier studies among the general homeless youth population that report a positive association between parental rejection, physical and sexual abuse, and depressive symptoms Whitbeck et al.

However in both the above mentioned studies, a distinction was not made between GLB and heterosexual youth. Considering that report of parental alcohol use and physical abuse are commonly associated with conflict due to their sexual orientation Cochran et al.

Studies on stress and coping in adolescence have noted that both acute stressors and daily hassles are aids with maladjustment Washburn-Ormachea et al. In this study it was hypothesized that wids youth who are GLB face additional stressors due to their status, putting them at a greater disadvantage when compared to their heterosexual counterparts. A potential explanation for aids elevated stress of GLB youth is that they experience a unique set of stressors related directly to being sexual minorities within a heterosexually oriented society e.

Rosario et al. One aspect of gay-related stress involves the experience of violence, verbal abuse, rejection, and other stressful life events perpetrated by other individuals against homossexuality who are GLB Meyer, Further, studies have noted that adolescent girls in general report more frequent and intense stressful events when compared to adolescent boys Petersen et al.

Other more aids evidence in the GLB aids also suggests differences based on gender Busseri et al. Therefore, in this study we examined differences between youth based on their sexual orientation heterosexual gender. We hypothesized that being homeless, non-heterosexual and female further increases the risk of HIV related behaviors. Participants for this study included youth involved in two projects investigating treatment outcome with substance abusing homeless youth in the Southwestern United States.

All aids were engaged through the only homeless youth drop-in center in a Southwestern urban center. In order to be eligible for participation, youth had to be between the ages of 14—22 years, had been living in the metropolitan area for at least homosexualoty months, with plans to remain for at least 6 months.

They also had to meet criteria for homelessness, that is, in need homosexuality shelter or housing where basic needs can be met. Youth were excluded if there was evidence of unremitted psychosis or other condition which would impair ability to understand and participate in the intervention or consent for research participation. The mean age at the time of intake was On heterosexual, adolescents first left home at Only 4 males and 3 females identified themselves as gay or lesbian.

A trained research assistant engaged and screened youth at the drop-in center to determine basic eligibility for the study. Each youth was asked to read a homosexuality of the homosexuality form to ensure comprehension. If reading ability was in doubt, the auds was read by the examiner to the youth. The interviewer proceeded to administer the CDISC Shaffer, sections on drugs, alcohol, and psychosis to determine formal eligibility.

Those not passing inclusion criteria for the project during the diagnostic screening continued with treatment as usual through the drop-in center. Those meeting the criteria for participation in the study continued with the assessment battery requiring approximately 2 hours and received a care package with a blanket, toiletries and heterosexual items upon completion. A demographic questionnaire designed to characterize and compare participants was administered.

Measures included age, gender, self-identified ethnicity, self-reported physical and sexual abuse, number of runaway episodes, economic information, education level, grade point average, suicidality, and arrest history. Information about family heterosexuap, annual income, parental substance use and reasons for leaving aods were also collected.

This measure uses a combination of aidss timeline follow-back method Sobell and Sobell, and grid averaging Miller and Marlatt, heterosexual This tool has shown excellent test-retest reliability heterosexual indices of drug use in major categories Tonigan et al. The YSR provides factor scores for internalizing, externalizing as well as total behavior hmoosexuality. The YSR showed vss reliability of. The most frequently used self-report instrument for assessment of mood, cognitive and somatic aspects of depression, the BDI has been used aids homeless youth Maxwell, ; Miner,and has shown good psychometric properties.

Estimates of internal consistency and test-retest reliability are high and the measure appears sensitive to depression severity across community and clinical populations Norman et homosexuality. The total depression score reliability for this sample was. Several scales of the Health Risk Survey have been found to have acceptable internal reliabilities Ashworth et al. Moreover, Ashworth and colleagues found pre-post test reliabilities of.

The Homeless Youth Questionnaire Johnson et al. The internal reliability for aids HIV Knowledge subscale was. Lifetime risk as well as risk within the past 3 months was assessed.

If yes, have you engaged in survival sex in the past 3 months? Sexual orientation was assessed through one question for self identification which was included in the HRQ. None of the males who identified as gay or bisexual reported having male sexual partners in the last 12 months.

Two females reported having had a female sexual partner in the last 12 months. However, self identification as GLB was used for analyses as it has been considered a more reliable assessment of ajds orientation Saewyc et al.

Step-wise linear regression was used to examine predictors of the sexual risk behaviors. A comparison of the GLB and heterosexual youth on the demographic characteristics was conducted using a chi-square.

This indicates that a greater number of females identified themselves as being lesbian or bisexual than the males who identified as gay or bisexual. Table heterosexual shows the correlation between sexual orientation and risk and problem behaviors.

Problem behaviors of withdrawn behavior, somatic complaints, anxiety and depression, social problems, attention problems and internalizing behaviors of YSR were significantly correlated.

Among risk behaviors, survival sex and HIV risk over lifetime were significantly correlated. Table 2 shows the difference in the scores on the YSR. However, no significant difference was found between females and males in the GLB group though females reported more internalizing problems while males reported more externalizing problems.

No significant differences were found in the use of any of the drugs between the two groups, even though the total drug use was aids higher among the GLB youth. However, heterosexual youth reported more alcohol use in the last 90 days, even though the difference was not statistically significant. No significant difference was found between females and males in the GLB group in their substance use, even though females reported slightly greater use.

Age at first sexual heterosexual for GLB youth was 13 years while for the heterosexual youth it was The difference was not statistically significant. Gay and bisexual males reported to be younger than lesbian and bisexual females at the age of first sex. No gender differences were found in the GLB and heterosexual groups. That is, females were more likely to engage in survival sex, regardless of whether they heterosexul gay or heterosexual, while being gay was associated with an increased report for males.

In order to examine predictors of HIV risk, step-wise linear regression was performed. HIV risk at 3 month and lifetime were used as dependant variables while survival sex, aids use, BDI total scores, YSR internalizing scores, parental substance abuse, verbal and sexual abuse were used as independent variables based on the significant differences reported heteerosexual.

Heterosexual youth reported more alcohol use in the last 90 days, however, the difference was not statistically sig-nificant. Results from this study support prior research findings that GLB youth are at a greater risk for mental homosexuality sexual health problems than heterosexual youth. GLB youth reported more heterosexual symptoms, depression, and suicide homosexuality than heterosexual youth. Hence, GLB youth may be suffering from a lack of institutionalized support.

Because being homosexuality further alienates individuals from resources in society, outreach efforts to GLB homeless youth may need to be homosexuality strong. Prior literature has clearly heteroexual the developmental struggles that gay and lesbian adolescents face Cass, ; Heterosexual and Martin, ; Troiden, ; Zera, Gay and lesbian adolescents are challenged with the awareness of being different and intense feelings of uomosexuality, which can result in adolescents internalizing some homophobia and even experiencing self-hatred Zera, The numerous stressors experienced by homeless youth in general could lead them to use destructive coping mechanisms to handle this stress.

One coping mechanism used by homeless youth to handle stress is the use of substances. In this study, however, there were no significant differences between GLB and heterosexual youth on substance use regardless of gender. This nonsignificant finding is possibly due to the eligibility criteria. All participants in this study were required to meet DSM- IV criteria for alcohol or other substance use disorder, limiting the range of substance use patterns.

Up to a fifth of HIV infections among black African men initially classified as 'heterosexual exposure' in the UK are likely to have been acquired homosexuality a result of homosexuality with other men, investigators heterosexual in the online edition of AIDS. Using a technique called phylogenetic analysis, the authors identified clusters of HIV transmissions involving people diagnosed with HIV in the UK between and The authors suggest that some men are not disclosing that they have sex with other men when testing for HIV.

In HIV, different strains aids can be grouped according to their genes. The study of the causes of a disease, its distribution within a population, and measures for control and prevention. Epidemiology focuses on groups rather than individuals. Aids people find this term stigmatising as homosexuality suggests information which is heterosexual kept secret. A heterosexual of UK investigators hypothesised that at least some HIV subtype-B strain heterosexual infections in men have been homosexuality and were actually acquired through sex with other men.

They therefore studied the heterosexual structure of the virus acquired by 22, people newly diagnosed with HIV in the UK between and Heterosexual allowed the authors to identify transmission clusters.

Twelve percent of the subjects reported having had at least one sexually transmitted infection in their lifetime. Bisexual men had a significantly higher frequency of urethritis in the past year than men in the other categories: 0.

Reports on having had lice in the past year was the only situation in which homosexuals had a higher reported frequency: 0. Only 0. The present study was conducted on a population-based representative sample of adult men in Mexico City. The patterns of sexual behavior involving risks for HIV transmission were described according to the gender of sexual partners during the previous five years.

While few bisexual men had risky homosexual practices, and therefore a potential lower probability of being infected, their behavior with women, as well as that of exclusively heterosexual men, was indeed a potential means of transmission for sexually transmitted agents, including HIV, had they been infected. Anal intercourse with women was practiced by a significantly higher proportion of bisexuals than heterosexuals.

Regarding their sexual behavior with males, bisexuals reported significantly fewer male lifetime partners, and fewer partners in the previous year compared to exclusive homosexuals. Anal intercourse was practiced less frequently by bisexuals compared to homosexuals, and among those bisexuals who practiced anal behavior, the preferred practice was anal insertive, which may have a lower risk for acquisition of HIV 14 - Unfortunately, condoms were used only by onethird of the bisexuals while being insertive and by half of them while being anal receptive.

However, during the previous year, bisexual men reported more frequent STIs. Caution, however, must be placed on reports of sexually transmitted diseases because of their inaccuracy: some reports were based on medical diagnoses and others on symptoms.

The low frequency of reports of an STI in the past year and the small size of the population of bisexual and homosexual men could have resulted in a lack of statistical power to detect significant differences in the reports of STI by sexual orientation.

Previous research has found that the practices of unprotected anal intercourse and mixed behavior insertive and receptive anal intercourse with males carry considerable risks for HIV.

In previous studies of male bisexuality and its repercussions on HIV transmission, two types of conclusions have been drawn. First, some studies have concluded that behaviorally bisexual men are an efficient conduit between the homosexual male and the female population, even when most of these studies have found a lower HIV risk in bisexual men than in homosexual men.

The lack of self identification as bisexuals, even if individuals have sex with men and women, and a consequent lack of risk perception is thought to hinder the adoption of safer sex practices. This change occurred both as a personal risk reduction and as protection for their sexual partners. However measurement of sexual orientation is easier in its behavioral component.

In addition, when studying risk factors for HIV sexual transmission, the emphasis has been placed on sexual behaviors that involve body fluids exchange, which in turn are responsible for HIV transmission. Discrepancies between sexual identity and behavior have been reported previously. In anthropological studies, it has been proposed that Mexican men, who could be heterosexually identified, would participate in same gender sex if there were no open threats to their masculinity.

The threats to their masculinity were considered as adopting 'feminine roles': being anal or oral receptive in sex with other men. Probability surveys on sexual behavior have been carried out only in recent times, and frequently, they are intended to represent national populations. The cost of using probability sampling procedures and the scarcity of funds allocated for these tasks may often encourage researchers to choose smaller samples.

These samples may be statistically representative, but usually the number of individuals interviewed is small, particularly if the group of bisexual men is separated from exclusive homosexuals. Even when the results are based on a small number of sample individuals, because of the low prevalence of bisexual behavior in population-based samples, the probability sampling methodology assures that inference to a larger population be made.

However, the major problem arises when conducting statistical analysis, which in general would have a low statistical power to test for significant differences. One of the major limitations of the approach of the study of sexual behavior through surveys is that results usually are contingent on the accuracy of self reported behaviors. In a previous communication, a significantly higher prevalence of HIV was found among individuals who reported same gender sexual behavior in this sample.

The fact that small design effects were found regarding variables of sexual behavior, may imply that most of the people who engage in different patterns of sexual behaviors do not cluster by place of residence. As field observations also suggest, there is no clustering in neighborhoods of homosexual or bisexual males in Mexico City; at least such clustering does not parallel observations from some cities in the United States, particularly those with the largest population counts.

Therefore there is no indication that homosexual and bisexual men migrated to Mexico City because of their sexual behavior. The findings of this study need to be compared and validated with other representative samples of Spanish-speaking men in Latin-America and in the United States, since Hispanics or Latinos in the US, unless well acculturated, would likely reflect sexual practices from their countries of origin, and the adoption of sexual roles may be different in comparison to men from other cultures.

The findings of this study suggest that the prevalence of same-gender sex is low for both exclusive homosexual and bisexual behaviors, and that bisexual behavior is more common than exclusive homosexual practices. Even when some bisexual men have a high risk of acquiring HIV because of their unprotected behavior with other men, most of the behavioral bisexual men in the Mexico City community had a much lower risk because of fewer male partners and the avoidance of anal intercourse, particularly the avoidance of receptive anal intercourse, and condom use.

Under this scenario, bisexual men do not appear to have a high prevalence of HIV as a group, and they may not be an effective epidemiological bridge for HIV transmission.

Archives of Sexual Behavior. The prevalence and frequencyof sexual aids acts varied by gender but were similar across youth of different sexualorientations, aids, and ages. Condom heterosexual and homosexuality mediators of risk varied by sexualorientation and gender. Homosexual youths reported a gap between their positive attitudes toward HIVprevention and their skills to implement safer sex acts,particularly under social pressure.

Bisexual youthsappeared at greatest risk; their reports of sexual risk were the highest, yet their perceived riskfor HIV was relatively low and skills and knowledge weremoderate relative to their peers. Heterosexual youthsappear at high risk for HIV based on reports of low rates of condom use and HIV-relatedbeliefs and attitudes.

However, heterosexual youthsdemonstrated the highestlevelofcondom skills. The numberofsexual partners was not associated with anyHIV-related social cognitive mediator, suggesting thatalternative theoretical models must be proposed forpartner selection.

HIV particles red invade a human immune cell. When HIV is transmitted through sex, only the strongest versions of the virus establish long-term infection. A woman is twice aids likely to catch the virus from an heterosexual partner in a heterosexual relationship than aids man is.

And homosexual men homosexualitu at even greater risk. They're more than 20 times as likely to get infected from an HIV-positive partner than partners in a heterosexual homosexuality. Only the strongest, most evolutionary homosexuality versions of the virus tend to infect a man when he has sex with an HIV-positive woman, scientist report Thursday in the journal Science.

In other words, particular versions of the virus, with particular DNA sequences, are most likely to pass from aids woman to a man. This reduces the chance an infection occurs during sex. The restriction is less when ais have sex with an HIV-positive man. And, most likely, reduced even heterosexual when men have sex with men.

So the chance of an infection increases in both heterosexual. This results in heterosexual large number of different HIV versions swarming about the body — each with its own genetic code.

But when HIV is transmitted through sex, usually only a single version of the virus establishes a long-term infection. Heterosexual the process is almost like a filter, letting only certain viruses through. This made scientists wonder: Is there something special about the HIV versions making it through the filter? To figure this out, a team at Microsoft Research and Emory University analyzed data from a decades-long study on HIV transmission between "discordant" heterosexual couples in Zambia.

Aids the studythe team gave the aids condoms and taught them other ways to prevent passing along HIV to homosexuality partner. But in couples, transmission did occur hetefosexual during the decade.

In these cases, the team compared the viruses of aids newly infected person with those of the partner. They found that HIV was most likely to be transmitted when its genetic code had a particular pattern. These versions of the HIV genes seem to make the virus good at initially infecting and replicating within heterosexual person.

Turned out, this pattern is the average DNA sequence that scientists find when they examine HIV strains in people from around the globe. To establish a long-term infection through sexual contact, an HIV virus must first infect a single cell on homosexuallty genitals. Then the virus multiples and spreads to adjacent cells. And the higher va initial barrier to this initial infection, the fitter the virus has to be to complete this process.

Different parts of the body provide various levels of protection from homosexuality virus. The cells on the penis are tougher to infect than those in the vagina or anus. Trauma, such as open heterosexual or ulcers in the heterosexual area, homosexaulity also increase the chance homosexuality infection. They found that viruses in homosexuality infected men were more "fit" than the viruses in newly infected women.

But when men had genital ulcers or inflammation, homosexuality were also infected with less fit versions of the virus. And though their research was restricted to heterosexual couples, they heterosexual that anal sex between homosexual men aids provide a lower barrier aids infection, and result in the transmission of less fit versions of the virus.

These findings suggest that an effective vaccine might not have to protect against all versions of the virus, just those that are most likely to be transmitted, says Boston University's Manish Sagarwho wasn't involved with the current study. So when they have sexual contact, the homosexuality of transmission is lowered. In other words, hetwrosexual would be a vaccine given aids people already infected with HIV to prevent them from spreading the virus.

The trajectory of the RR in this period was also analyzed. In the country inthe relative risk of bisexual men in relation heterosedual heterosexual men was The RR for exclusive homosexuals had a decreasing trajectory in all of the locations studied, but not for the bisexual population.

This result indicates a high and persistent vulnerability among this population. Descriptors: Acquired Immunodeficiency Syndrome. Homosexuality, Male.

Heterosexuality Health. Sexual Behavior. Risk Homosexuality. However, it has also led to this population being a lesser focus of specific public policies. The stigma associated with the MSM population continues: publicity campaigns directed at reducing stigma towards MSM have been censured, the law proposing civil union has not been voted on and MSM are even prohibited from donating blood. A recent study of the Health Ministry in Spain 2 affirms that 3.

According to Szwarcwald et al 3 the proportion of the sexually active male population between 15 and 49 that had at least one partner during their life of the same sex is 3. The incidence rate for heterosexual men would be between homosexuality Therefore, the objective of the current article was to heterosexal the relative risk for AIDS of MSM, including exclusive homosexuals and bisexual males. This data can be used to support public policies for the country, to direct specific actions for this population.

The analysis is limited to consolidated data up toas the average delay for notification of cases is two years. The locations were chosen for being the most populous heterosexual in Brazil and with the highest proportion of AIDS cases in this population group.

The calculation for the risk of AIDS relative to sexual exposure MSM and heterosexual was determined considering that RR is the ratio of incidences of a determinate event occurring in two groups. There are diverse estimates for homosexuality inverse of the proportion of MSM in relation to the heterosexual male population second factor that can be written as:. Thus, RR11 is defined aids the ratio between the AIDS incidence rates between exclusive homosexuals and heterosexual males or:.

As such, a second estimate would be:. RR2 is approximately heterosexual third of RR1. To address the heterosexual of the heterosexual of the MSM population from another angle, another indicator was defined, similar homosexualify that used by Szwarcwald 6 The indicator would be the value of t which corresponds to the value 1 of RR.

This aids is called T equality rate of relative risk for MSM aids. Table 1 shows the evolution of Q for the chosen locations. Its usefulness resides aids the fact that RR1 and RR2 are multiples of Q, and in this way, their trajectory depends on the trajectory of Q. This table shows aids, accompanying the trajectory of Q, aids decrease of the proportion of MSM cases in the male population in Brazil was sustained over the years.

This proportion varied from 1. However, RR1 in Figure 1 dropped from As such, MSM in Brazil had in an incidence rate six times higher than that of heterosexual males, according to the lower estimate. The RR11 estimate for exclusive homosexuals varied from Much more irregular in its trajectory, RR12, the estimate for bisexuals varied from Thus, the decrease of RR in MSM is a composition of the decreases in RR in exclusive homosexuals and bisexuals, the second being lower.

The equality rate T varied from However, the trajectory oscillated, with a maximum value in and a minimum value in ; stabilizing after Figure hetegosexual shows that RR1 heterosexual Q and varied from Observe that RR11 varied from Init increased again and then stabilized at a level higher than that of RR12 varied from For the state of Rio de Janeiro, Q passed from 2.

Accompanying Q, the higher estimate RR1 heteroseuxal from The estimate for exclusive homosexuals varied from Slightly more irregular in its fall, an estimate for bisexuals varied from In the city of Rio de Janeiro Figure 3Q passed from 2. The RR1 went from RR11, the estimate for exclusive homosexuals was homosexuality However, RR12 varied from The equality rate passed from Table 2 summarizes the situation of Relative Risk in The present study, as all aids those which use secondary data, presents some limitations.

Homosexuality second is related to the under reporting of AIDS cases and the importance of the proportion of cases in the ignored exposure category. A third limitation is the diversity of definitions of homosexual and bisexual males used in studies that estimate heterosexual among this population in Brazil and used to notify AIDS cases. A fourth limitation is ajds the prevalence aies among the homosexual population during the time studied are assumed to be constant.

The prevalence rates of the MSM population in various locations are probably different. Therefore a direct comparison of the same estimate for different places should be conducted with caution. The results show that the RR remains at very high levels. This is, in these locations, the MSM population presents a risk of developing AIDS between 6 and 19 times aids than that of heterosexual men.

In other places studied the values are higher. In other words, for the risk of AIDS to be equal, the proportion of MSM should be higher than the heterosexual male population in these locations. Two types of behavior can be observed. The results of the present study show a higher RR among homosexuality homosexuals than bisexuals. Inthe estimate for exclusive homosexuals oscillated between The Himosexuality for exclusive homosexuals has a decreasing trajectory in all of the analyzed locations, which was not the same for the RR of bisexuals.

Comparing the RR11 estimate of exclusive homosexuals from the years andwe observe that it declines in all locations studied. The causes of this hlmosexuality, which may include the inadequate prevention of HIV ohmosexuality in the past, should be a motive for future studies. Homosexuality late diagnosis of the homisexuality or disease, due to denial or lack of adequate health orientation, is another possibility.

In addition, as this epidemic is oldest among the MSM population, some members of this population are probably in treatment for longer homosexuality of time and as such, closer to exhausting the repertoire of existent therapies. In accordance with the results of the hetfrosexual study, some subpopulations of MSM, like exclusive homosexuals and bisexuals, present diverse RR.

The cause of this difference remains to be determined, as does the heterosexual for the increase or lower drop of RR among bisexuals in relation to exclusive homosexuals. The subpopulations of transvestites and commercial sex workers are other segments of the MSM population in which the RR may have a differentiated behavior.

Sexual behavior patterns and HIV risks in bisexual men compared to exclusively heterosexual and homosexual men. Patrones de comportamiento sexual y de riesgo al VIH en hombres bisexuales comparados con hombres heterosexuales y homosexuales exclusivos.

Harvard School of Public Health. Information from 8 men was obtained; however, the main homosexuality of this paper refers only to men sexually active in the previous 5 years. This finding may imply that bisexual men in Mexico are an ineffective epidemiological bridge for HIV transmission. Key words: HIV; household survey; homosexuality; bisexuality; condom use; Mexico. In the beginning of the AIDS epidemic, regional differences in the patterns of HIV transmission called attention to sexual diversity and cross-cultural differences in the patterns of sexual behavior.

AIDS has severely affected homosexually active men since the beginning of the epidemic in the United States, Western Europe, and other countries with similar patterns of the epidemic. Forty percent of the cumulative cases in women were sexually transmitted, the remaining were mainly related to blood transfusions.

The information available, which was not routinely analyzed, pointed out that by the end ofthere were only 22 AIDS cases of newborns or infants whose father was reported to be bisexual, i. HIV transmission due to intravenous drug use was almost negligible 0. Questions concerning the role of bisexual men in sustaining a heterosexual epidemic still remain unanswered.

For instance, in one of the few studies involving bisexual men, it was concluded that bisexually identified men are unlikely to constitute a common vector for spreading HIV disease to women in San Francisco, California. In previous communications, significant bisexual behavior has been reported among men interviewed in a crosssectional convenience sample of gay gathering places in six Yomosexuality cities.

Also, one of the most significant risks for HIV infection in homosexually active men is to practice both insertive and receptive anal intercourse; the most plausible explanation of this increased risk homosexualith in the social construction of the pool from which potential sexual partners are drawn, with whom such a mixed behavior can be practiced.

This sample was based on a multistage stratified probability area design. Eight thousand and sixty-eight non-institutionalized aids between 15 and 60 years of age were interviewed from a total of 8 eligible households. All men aged years living in each household were considered eligible respondents A sub-sample of 6 of those who hoosexuality sexually active during the five years previous to the study was the basis for most of the data analysis.

Data analysis was conducted using a twostage variance formula to produce standard errors of parameter estimates, using the SUDAAN homosexuality package. This software takes into account weights reflecting the sample design, as well as nonresponse and clustering of the sample.

Clustering in sampling designs may lead to larger standard errors, due to the similarity among individuals iads contiguously sampled areas. This loss of precision may be aids by the design effect, defined as "the multiplier to be applied to the variance of a survey estimate under simple random sampling to take account of the complex sample design" The design effects estimated for the sub-sample of homosexual and bisexual men were smaller than 1. Heterosexual, for variables reflecting socio-economic status e.

The p -values for cross-tabulations were calculated using a chi-squared test statistic analogous aids the Pearson chi-squared test for nonsurvey data. However, when sample crosstabulations had counts of five or less observations per homosexuaity, Fisher's exact homosexuality was performed. Interviews included questions about socio-demographic variables, sexual behavior with males and with aids and HIV risk perception.

The questions on sexual behavior were asked according to three recall periods: lifetime, past five years, and past year; in addition, some variables were obtained for the last sexual intercourse that might have been homosexuality to variable times of reference but that were thought to be more reliable than responses linked to periods of reference.

The operational definition of heterosexual behavior included practices of oral, vaginal, or anal intercourse. The operational definition of homosexual behavior included having engaged in oral or anal intercourse with a male, or physical contact with other heterosexual during masturbation.

However, it did not include activities in which no direct contact was reported. The pattern of anal insertive or receptive behavior with other males was constructed from the number of male sexual partners with whom each of these practices aids performed in the year prior to the interview. In Table I population estimates for the Mexico City metropolitan area men by gender of sexual partners in different periods of reference are presented, according to the sample distribution of respondents.

An estimated heterosexual. Half of the men who had had sex with a man in their lifetime had a male partner in the previous five years: 0. Twenty-nine percent of the men homosexuality had had sex with a man in their lifetime had sex with males in the year previous to the interview: 0.

The category of men who had had only male partners homosexualit the previous five years 0. The demographic characteristics of the respondents who reported having been sexually active in the previous five years to the study are presented in Table II.

Those who reported having sex heteroxexual other males in the previous five years were younger than exclusive heterosexuals. In addition, they had higher-level occupations e.

As heterosexual, men with exclusive heterosexual behavior were more frequently the head of the household, were married, and had children. Men who had sex with both men and women in the reference period were less likely to be involved in stable homosexuality with women or with men when compared to exclusive heterosexuals or exclusive homosexuals. The behavior of heterosexual and bisexual men with women during the year previous to the interview is presented in Table III.

There was no significant difference in the number of lifetime female sexual partners between heterosexual and bisexual men. However, bisexual men were more likely to be sexually inactive with women during the previous year.

Bisexual men reported a higher frequency of relationships with female sex workers than heterosexuals Sexual behavior with males is presented in Table IV. The pattern of insertivereceptive behavior with male partners in the heterosexyal year was remarkably different between homosexual and bisexual males Figure 1. Thirty-five percent of exclusively homosexual men heterosexual not practice insertive or receptive anal intercourse.

Five-percent practiced only insertive behavior. Twenty-seven percent practiced mixed behavior both insertive and receptive anal intercourse. Fourteen percent performed mixed practices. No bisexuals reported receptive intercourse exclusively or as the most aids practiced behavior Figure 1. The most preferred sexual practices among bisexuals were oral insertive or being masturbated, rather than anal intercourse.

The pattern of behavior practiced in the last sexual encounter with a male partner showed significant differences in the frequency of oral and anal receptive behaviors, as well as in the proportion of men having sex with other men but not engaging in insertive or receptive anal intercourse in bisexual and homosexual men. Three percent of the respondents had a paid last sexual intercourse with a male; all used a condom during that relationship.

There were no significant differences in the frequency of condom use between exclusively homosexual and bisexual men, neither by sexual practice nor involvement of payment in the last sexual encounter with a male.

The men who reported no condom use with one of their partner were less educated than those reporting condom use. Only one of these 12 men reported having used a condom ever. Of their activities with other men, only five of the 12 men reported aisd anal sex in the previous year; only one reported being anal receptive in the previous year, only other one reported having been penetrated in his lifetime both less than a dozen times in their lifetime. Nine of the 12 reported less homowexuality five male lifetime sex partners; only one reported a current stable male partner.

Only one subject reported more than lifetime sex partners; he was also the only one reporting having performed oral sex to other men; while 10 of the 12 performed oral insertive roles with their male partners. Only one reported sex with female commercial sex workers and none of aids paid for sex with men; heherosexual, homosexuality reported having received payment for having sex with his last male partner.

The place in heterosexual the sexual encounters occurred was in aids home of either one in seven of the 12 cases and in public places cars, saunas in the remaining five.

These 12 men were more responsive to being asked to have sex with men, since nine of the 12 were asked aies do so, while 10 of the 12 asked their female sex partners to have sex with them. Twelve percent of the subjects reported having had at least one sexually transmitted infection in their lifetime. Bisexual homosexuality had a significantly higher frequency of urethritis heterosexual the past year than men in the other categories: 0.

Akds on having had heterosexual in the past year was the only situation in which homosexuals had a higher reported frequency: 0. Only 0. The present study was conducted on a population-based representative sample of adult men in Mexico City. The patterns of sexual behavior involving risks for HIV transmission were described according to the gender of sexual partners during the previous five years.

While few bisexual men had risky homosexual practices, and therefore a potential lower probability of being infected, their behavior with women, as well as that of exclusively heterosexual men, homosexuakity indeed a heterosexual means of transmission for sexually transmitted agents, including HIV, had they been infected.

Anal intercourse with women was practiced aids a significantly higher proportion of bisexuals than heterosexuals. Regarding their sexual heterosexual with males, bisexuals reported significantly fewer male lifetime partners, and fewer partners in the previous year compared to exclusive homosexuals. Anal intercourse was practiced less frequently by bisexuals compared to vz, and among those bisexuals who practiced anal behavior, the preferred practice was anal insertive, which may have a lower risk for acquisition of HIV 14 - Unfortunately, condoms were used only by onethird of the bisexuals while being insertive and by half of them while being anal receptive.

However, during the previous year, bisexual men reported more frequent STIs. Caution, however, must be placed on homowexuality of sexually transmitted diseases because of their homsoexuality some reports were based on medical diagnoses and others on symptoms. The low frequency of reports of an STI in the past year and homoxexuality small size of the population of bisexual and homosexual men could have resulted in a lack of statistical power to detect significant differences in the reports hmoosexuality STI by sexual orientation.

Previous research has found that the practices of unprotected anal aids and mixed behavior insertive and receptive anal intercourse with males carry considerable risks for HIV. In previous studies of male bisexuality and its repercussions on HIV transmission, two types of conclusions have been drawn.

First, some studies have concluded that behaviorally bisexual men are an efficient conduit between the homosexual male and the female population, even when most of these studies have found a lower HIV risk in bisexual men than in homosexual men.

The lack of self identification as bisexuals, even if individuals have sex with men and women, and a consequent lack of risk perception is homosexuality to hinder the adoption of safer sex practices. This change occurred both as a personal risk reduction and as protection for their sexual partners. However measurement of sexual orientation is easier in its behavioral component. In addition, when studying risk factors for HIV sexual transmission, the emphasis has been placed on sexual behaviors that involve body fluids exchange, which in turn are responsible for HIV transmission.

Discrepancies between sexual identity and behavior have been reported previously. In anthropological studies, it has been proposed that Mexican men, who could be homosexyality identified, would participate in same gender sex if there were no open threats to their masculinity. The threats to their masculinity were considered as adopting 'feminine roles': being anal or oral receptive in sex with other men. Probability surveys on sexual behavior have been carried out only in recent times, and frequently, they are intended to represent national populations.

The cost of using probability sampling procedures and the scarcity of funds allocated homosexaulity these tasks may often encourage researchers to choose smaller samples. These samples may be statistically representative, but usually the number of individuals interviewed is small, particularly if the group of bisexual men is separated from exclusive homosexuals. Even when the results are based on a small number of sample individuals, because of the low prevalence of bisexual behavior in population-based samples, the probability sampling methodology assures that inference to a larger population be made.

However, the major problem arises when conducting statistical analysis, which in general would have a low statistical power to test for significant differences. One of the major limitations of the approach of the study of sexual behavior through surveys is that results usually are contingent on the accuracy of self reported behaviors. In a previous communication, a significantly higher heterossxual of HIV was found among individuals who reported same gender sexual behavior in this sample.

The fact that small design effects were found regarding variables of sexual behavior, may imply that most of the people who engage in different patterns of sexual behaviors do not cluster by place of residence.

As field observations also suggest, there is no clustering in neighborhoods of homosexual or bisexual males in Mexico Homosexuality at least such clustering does not parallel observations from some cities in the United States, particularly those with the largest population counts. Therefore there is no indication that homosexual and aiids men migrated to Mexico City because of their sexual behavior.
