ABSTRACT To examine the transmission behavior among youth living with HIV (YLH), pre- and post-HAART.
Two cohorts were recruited: (1) 349 YLH during 1994 to 1996 and (2) 175 YLH during 1999 to 2000, after the wide availability of HAART. Differences in sexual and substance-use risk acts and quality of life were examined.
Post-HAART YLH were more likely to engage in unprotected sex and substance use, to be more emotionally distressed, and to have lower quality of life than were pre-HAART YLH.
Targeted interventions for YLH that address reductions in transmission acts and aim to improve quality of life are still needed.

    • "Interest lies in comparing the two intervention delivery modes, comparing treatments to control, and in estimating effects of predictors known to be important. Our outcome in this paper is the self-reported number of sexual partners during the past three months, an important measure of sexual risk behavior (Rotheram-Borus et al. 2001; Lightfoot et al. 2005).

    ABSTRACT: We analyze longitudinal self-reported counts of sexual partners from youth living with HIV. In self-reported survey data, subjects recall counts of events or behaviors such as the number of sexual partners or the number of drug uses in the past three months. Subjects with small counts may report the exact number, whereas subjects with large counts may have difficulty recalling the exact number. Thus, self-reported counts are noisy, and mis-reporting induces errors in the count variable. As a naive method for analyzing self-reported counts, the Poisson random effects model treats the observed counts as true counts and reporting errors in the outcome variable are ignored. Inferences are therefore based on incorrect information and may lead to conclusions unsupported by the data. We describe a Bayesian model for analyzing longitudinal self-reported count data that formally accounts for reporting error. We model reported counts conditional on underlying true counts using a linear birth-death process and use a Poisson random effects model to model the underlying true counts. A regression version of our model can identify characteristics of subjects with greater or lesser reporting error. We demonstrate several approaches to prior specification.

    • "There is a great deal of literature describing the sexual risk behaviors of HIV+ youths who were behaviorally infected, with these youths engaging in a higher prevalence of sexual risk behaviors than the general population (Kadivar et al. 2006; Koenig et al. 2007; Lightfoot et al. 2005; Murphy et al. 2001; Naar-King et al. 2006). Extrapolating data from samples of adolescents with behaviorally acquired HIV, however, may be inadequate or insufficient to tailor harm reduction strategies for PHIV youth. "

    ABSTRACT: A large proportion of perinatally HIV-infected (PHIV) children are becoming adolescents and exploring their sexuality. This study explored the prevalence of sexual behaviors (kissing, touching, engaging in oral sex, or having vaginal/anal intercourse) in a sample of predominantly ethnic minority youths (N = 339; 54.1% Black and 30.4% Latino; 51% female; ages 9-16) perinatally exposed to HIV (61% HIV+). Using logistic regression, we tested the association between sexual behavior and HIV status, demographic characteristics, and peer influences regarding sexual behavior. PHIV youth were less likely to be sexually active. Among sexually active youth, PHIV youth were more likely to engage in touching behavior than HIV-negative youth and were less likely to engage in penetrative sex. Youths reporting that a greater number of their peers believed that sexually active boys were "cool" or "popular" were more likely to report sexual behavior. The association between sexual behavior and peers believing sexually active girls were "cool" or "popular" varied by age, gender, and HIV status. Furthermore, friends' sexual activity was associated with sexual intercourse. Prevention programs should strengthen messages addressing peer norms regarding sexuality, as well as address specific issues related to adolescent HIV.

    ABSTRACT: In developing countries, access to antiretroviral therapy (ART) is improving as HIV treatment becomes a greater priority in the global fight against AIDS. While ART has clearly beneficial clinical effects, increased access to treatment may also affect sexual behaviour. To examine the strength of evidence for the impact of medical treatment for HIV-positive individuals on behavioural outcomes in developing countries, we conducted a comprehensive search of the peer-reviewed literature. Studies were included if they provided clinical treatment to HIV-positive individuals in a developing country, compared behavioural, psychological, social, care, or biological outcomes related to HIV-prevention using a pre/post or multi-arm study design, and were published between January 1990 and January 2006. Only three studies were identified that met the inclusion criteria. All were conducted in Africa, utilized before/after or multi-arm study designs, and relied on self-reported behaviour. In all three studies, a majority of HIV-infected individuals reported being sexually abstinent, and access to ART was not associated with an increase in HIV-related risky sexual behaviours. However, one cross-sectional study found that ART patients were more likely to report STD treatment. The available evidence indicates a significant reduction in risk behaviour associated with ART in developing countries. However, there are few existing studies and the rigor of these studies is weak. More studies are needed to build an evidence base on which to make programmatic and policy decisions.
