Predictors of unprotected male-to-male anal intercourse with casual partners in a national sample

Abstract: The focus of the paper is the predictors of unprotected anal intercourse with casual partners among a national Australian sample of homosexually active men. We interviewed by telephone 2583 homosexually active men (sex with a man within the last five years) about their sexual practice, type of sexual partners, human immunodeficiency virus (HIV) test status, attachment to the gay community, knowledge of HIV and acquired immune deficiency syndrome (AIDS) and a range of demographic variables. Logistic regression analyses were used to distinguish men who practised unprotected anal intercourse with casual partners from those who practised safe sex with casual partners. Men who practised unprotected anal intercourse with casual partners were less likely to have a regular male sexual partner than men who practised safe sex with their casual partners. They were less likely to be tertiary educated, more likely to be employed in trade and manual occupations and to live in Tasmania and the Northern Territory. They were less likely to be culturally or politically attached to the gay community. Knowledge of HIV/AIDS also distinguished the men: men with an accurate knowledge of HIV transmission were less likely to engage in unprotected anal intercourse with their casual partners. Several other variables, including age and HIV test status, did not distinguish those who practised safe sex with casual partners from those who practised unprotected anal intercourse with casual partners.     

Nutritional effects of oral contraceptives

In this research we investigate factors associated with nonuse of condoms for sexually active Botswana women. Nationally represented data, drawn from the 2004 Botswana AIDS Impact Survey, were used. A sample of 5,236 women aged 15–49 who have had sexual intercourse was considered for the analysis. Cross-tabulations were used to gain insights into the phenomena to be reinforced with logistic regression. Through logistic regression analysis, we reveal that the relative odds of having had no HIV/AIDS tests, had an older sexual partner, and had sexual intercourse intoxicated under alcohol were significantly less among teenagers and women aged 20–34. It is shown that women with primary education were less likely to have been tested for HIV/AIDS and have had sexual intercourse while intoxicated. Christians were less likely to have had sexual intercourse while intoxicated. Last, women who did not use condoms at last sexual intercourse were significantly more likely to have had sexual intercourse while under the influence of alcohol, had older sexual partners, and believed that people cannot reduce their chances of getting HIV/AIDS by using a condom.     

Determinants of condom use and heterosexual multiple sexual partnership in French Antilles and French Guiana

BACKGROUND: After Subsaharan Africa, the Caribbean is the world's region most affected by HIV/AIDS. The French-American departments (Guadeloupe, Martinique, Guiana), FAD, are located in the heart of this region. Although lower than in other states of the Caribbean, AIDS incidence is much more higher than in France (up to 15 times more in Guiana). Transmission is mostly heterosexual. The frequency, particularly among men, of multiple sexual partnerships frequently taking place concurrently, and the persistence of this activity in older age, contribute to the level of the HIV epidemic and its characteristics. The purpose of this article is to identify, in the FAD, the determinants of condom use among persons with multiple sexual partners (either at last intercourse or during a concurrent relationship), taking into account the variety of multiple sexual partnership situations. METHOD: Data are taken from an HIV/AIDS KABP survey, based on a probability sample of men and women aged 18 to 69 years, resident in FAD. In total, 3104 interviews were conducted by telephone in 2004: around 1000 in each department. RESULTS: Among men and women who report two or more partners in the past five years, there is substantial heterogeneity in level of condom use at last intercourse, depending on the duration and type of the relationship: 73% of respondents reported condom use with a casual partner and 14% with a cohabiting partner. Men and women who were engaged in concurrent partnerships in the past five years were at higher risk of infection: 7% reported an STI versus 4% among those who had two or more partners, but not at the same time. Women, older persons, people with a lower level of education and those engaged in concurrent partnerships reported a lower level of condom use, thus increasing their vulnerability to HIV/AIDS. CONCLUSION: Although HIV/AIDS prevention has increased among male and women engaged in multiple sexual partnerships, there is still a lack of consistent condom use in this population. These results highlight the need for more diversified prevention programs, taking into account sociodemographic factors and the diversity of situations involving multiple sexual partnership.

Interactions between persons at risk for AIDS and the general population in Denmark.

A nationwide study of sexual behavior was undertaken among 4,680 randomly selected Danes aged 18-59 years. The median number of sexual partners (lifetime) was highest for men aged 30-34 years (eight partners) and for women aged 25-29 years (seven partners). After adjustment for age and sex, having had greater than or equal to 5 sexual partners in the past year was strongly associated with living in larger cities, intravenous drug use, and having sex with a prostitute, a bisexual man, an intravenous drug user, or a resident of sub-Saharan Africa. The frequency of ever having had anal intercourse was highest among women aged 20-34 years (range, 27%-36%) and was independently associated only with increasing number of sexual partners (lifetime). Overall, 2.7% of men reported any homosexual experience, among whom most (88%) had also had heterosexual intercourse. Prostitute contact (ever) was reported by 13% of all men and was associated with a high educational level, a history of travel, a greater number of sexual partners, and intravenous drug use. Overall, sexual contact with someone considered at high risk of human immunodeficiency virus (HIV) infection (a homosexual/bisexual man, intravenous drug user, prostitute, or sub-Saharan African resident) was reported by 15.9% of men and 4.8% of women. Among active blood donors (past year), 12.5% of men and 4.0% of women had engaged in potentially risky behavior. HIV testing was deliberately sought more often by respondents exposed to someone at increased risk of HIV infection (10.6%) than by those unexposed (6.5%, p less than 0.01). Exposure to persons at risk of HIV infection is considerable in Denmark. The majority of persons who have had potential exposure to HIV have not yet been tested for HIV.     

北京市大学在校生男男性行为者HIV感染状况及其相关危险陛行为调查

目的 了解北京市大学在校生男男性行为者的HIV感染状况及其相关危险性行为.方法 研究对象主要通过网络招募,采用自填式问卷调查.问卷内容包括人口学信息与艾滋病相关危险行为等.问卷完成后采集血液样本进行HIV血清学检测.单因素分析采用X2检验,多因素分析采用logistic同归.结果 研究成功招募157人.平均年龄为(22.7±2.8)岁,少数民族占12.1%,77.7%自我认同为同性恋.98.1%曾有肛交行为,73.9%报告肛交是常采用的性行为方式.157人中近6个月有58.6%发生过无保护肛交,有58.0%口交时从不使用安全套,其中59.2%存在多性伴(性伴数≥2)行为.近50.0%认为自己不可能感染HIV或者风险很小,检测发现HIV阳性率为2.5%.logistic回归分析结果 显示,曾与陌生人发生性行为(OR=13.10)、了解"肛交时做主动方比做被动方感染HIV风险小"(OR=3.37)以及曾去同性恋酒吧(OR=2.49)是近6个月发生多性伴行为的独立危险因素.结论 大学在校生男男性行为者无保护肛交和多性伴行为较普遍.亟需开展有针对性的干预活动,预防HIV在该人群中传播.

Abstract：

Objective To assess the prevalence of HIV and risky sexual behaviors among university students who have sex with men(MSM)in Beijing.Methods MSM students in the universities were mainly recruited via internet.Questionnaires were self-administered to collect social demographic information and AIDS-related risky sexual behaviors.After completing the questionnaire,blood sample was collected to determine HIV infection through serological testing.X2 test and logistic regression were employed for univariate and multivariate analysis,respectively.Results A total of 157 students were recruited with mean age of 22.7±2.8 years old,12.1%of them were minorities and 77.7% were self-identified as homosexual.98.1% had engaged in anal intercourse(AI)in their lifetime and 73.9%reported that AI was common sexual behavior they often practised.In the past 6 months,58.6% had ever had unprotected anal intercourse(UAI),58.0% never used condoms during oral intercourse,and 59.2% had multiple sex partners(≥2).Nearly half of them believed that they were at low or no risk of contracting HIV and the prevalence of HIV infection was 2.5%.Data from logistic regression analysis showed that ever having had sex with a casual partner in a lifetime (OR=13.10).understanding that serving an insertive role had less risk than being receptive during the AI (OR=3.37),and ever having been to a gay bar(OR=2.49)was independently related to having multiple sex partners in the past 6 months.Conclusion Despite the extensive programs on education,behaviors regarding UAI and ever having had multiple sex partners were silll commonly seen among university MSM students.Interventions were needed to prevent HIV transmission in this population.
