BACKGROUND There is a heavy and disproportionate burden of human immunodeficiency virus (HIV) infection among migrant communities living in Europe. Despite this, the published evidence related to HIV testing, prevention, and treatment needs for migrants is sparse. OBJECTIVE The aim of this study was to identify the factors associated with access to primary care and HIV testing among migrant g...

OBJECTIVE To assess non-participation bias in a survey of male sexual behavior. MATERIAL AND METHODS A household survey was carried out in 1992-1993 using a probability sampling frame in Mexico City. Demographic variables were available for all eligible men. The extent of non-participation bias was estimated using a version of the Heckman method, which utilizes two equations, one to predict p...

The prevalence of male same-gender sexual behavior in Mexico City in relation to HIV transmission was studied. A household probability survey of 8,068 adult men was conducted in 1992-93 using the Mexican National Health Survey sampling frame. The response rate was 59%. Differences between respondents and nonrespondents indicated no evidence for significant bias. A random subsample of 1,116 indi...

We examined reports of sexual orientation identity stability and change over a 10-year period drawing on data from the National Survey of Midlife Development in the United States (MIDUS I and II) and tested for three patterns: (1) heterosexual stability, (2) female sexual fluidity, and (3) bisexual fluidity. Fifty-four percent of the 2,560 participants were female and the average age was approx...

Men's, more than women's, sexual responses may include a coordination of several physiological indices in order to build their sexual arousal to relevant targets. Here, for the first time, genital arousal and pupil dilation to sexual stimuli were simultaneously assessed. These measures corresponded more strongly with each other, subjective sexual arousal, and self-reported sexual orientation in...

There is evidence that risks for HIV and sexually transmitted infections among adolescent females are higher for those with older male sexual partners. Yet, little empirical research has been conducted with male adolescents who engage in sexual activity with older men. In this article, we summarize in a number of ways the range of sexual activity reported by an ethnically diverse sample of 200 ...

BACKGROUND Sex with multiple partners (SMP) is one of the important contributing factors for contracting sexually transmitted infections (STIs) among adolescents and young adults, especially among Lesbian, Gay, and Bisexual (LGB) youth. Past studies mainly focus on examining associations of alcohol or club drugs use with unprotected sexual behaviors among adult homo/bisexual men, while little i...

OBJECTIVE Few population-based studies have explored differences in alcohol consumption by sexual orientation. This study examined the prevalence of abstinence, drinking, heavier drinking, alcohol-related problems, alcohol dependence and help-seeking among homosexual and bisexual women and men compared with heterosexuals. METHOD Data are from the 2000 National Alcohol Survey, a national popul...

Club drugs such as methylenedioxymethamphetamine (MDMA, ecstasy), gamma hydroxybutyrate (GHB), and ketamine are among the fastest-growing drugs of abuse in the United States. Reports have shown that some gay and bisexual men are likely to engage in club-drug use in a myriad of venues. This is concerning given that the use of club drugs has been linked to high-risk sexual behaviors. Further, the...

Using data from a US national probability sample of self-identified lesbian, gay, and bisexual adults (N = 662), this article reports population parameter estimates for a variety of demographic, psychological, and social variables. Special emphasis is given to information with relevance to public policy and law. Compared with the US adult population, respondents were younger, more highly educat...
