Objectives. We measured the extent to which a set of psychosocial health problems have an additive effect on increasing HIV risk among men who have sex with men (MSM). Methods. We conducted a cross-sectional household probability telephone sample of MSM in Chicago, Los Angeles, New York, and San Francisco. Results. Psychosocial health problems are highly intercorrelated among urban MSM. Greater numbers of health problems are significantly and positively associated with high-risk sexual behavior and HIV infection. Conclusions. AIDS prevention among MSM has overwhelmingly focused on sexual risk alone. Other health problems among MSM not only are important in their own right, but also may interact to increase HIV risk. HIV prevention might become more effective by addressing the broader health concerns of MSM while also focusing on sexual risks.

Review from JAMA — Highly Active Antiretroviral Therapy and Sexual Risk Behavior — A Meta-analytic Review — ContextEvidence suggests that since highly active antiretroviral therapy (HAART) became available, the prevalence of unprotected sex and the incidence of sexually transmitted infections (STIs) have increased.ObjectiveTo conduct 3 meta-analyses to determine whether (1) being treated with HAART, (2) having an undetectable viral load, or (3) holding specific beliefs about HAART and viral load are associated with increased likelihood of engaging in unprotected sex.Data SourcesA comprehensive search included electronic bibliographic databases, including AIDSLINE, MEDLINE, PubMed, CINHAL, PsycInfo, ERIC, EMBASE, and Sociofile, from January 1996 to August 2003, conference proceedings, hand searches of journals, reference lists of articles, and contacts with researchers.Study SelectionTwenty-five English-language studies (some contributing >1 finding) met the selection criteria and examined the association of unprotected sexual intercourse or STIs with receiving HAART (21 findings), having an undetectable viral load (13 findings), or beliefs about HAART and viral load (18 findings).Data ExtractionReports were screened and information from eligible studies was abstracted independently by pairs of reviewers using a standardized spreadsheet.Data SynthesisRandom-effects models were used to aggregate data. The prevalence of unprotected sex was not higher among persons with the human immunodeficiency virus (HIV) receiving HAART (prevalence range, 9%-56%; median, 33%) vs those not receiving HAART (range, 11%-77%; median, 44%; odds ratio [OR], 0.92; 95% confidence interval [CI], 0.65-1.31) or among HIV-positive persons with an undetectable viral load (range, 10%-68%; median, 39%) vs those with a detectable viral load (range, 14%-70%; median, 42%; OR, 0.99; 95% CI, 0.82-1.21). The prevalence of unprotected sex was elevated (OR, 1.82; 95% CI, 1.52-2.17) in HIV-positive, HIV-negative, and unknown serostatus persons who believed that receiving HAART or having an undetectable viral load protects against transmitting HIV or who had reduced concerns about engaging in unsafe sex given the availability of HAART (range, 17%-81% [median, 49%] vs 9%-68% [median, 38%] for counterparts).ConclusionsIn the studies reviewed, HIV-positive patients receiving HAART did not exhibit increased sexual risk behavior, even when therapy achieved an undetectable viral load. However, people's beliefs about HAART and viral load may promote unprotected sex and may be amenable to change through prevention messages.

The Brief Fear of Negative Evaluation Scale (BFNE; M. R. Leary, 1983a) is often used to assess fear of negative evaluation, the core feature of social anxiety disorder. However, few studies have examined its psychometric properties in large samples of socially anxious patients. Although the BFNE yields a single total score, confirmatory factor analysis indicated a 2-factor solution to be more appropriate, with the 1st factor consisting of all straightforwardly worded items (BFNE-S) and the 2nd of all reverse-scored items (BFNE-R). Support was obtained for the convergent and discriminant validity of the BFNE and BFNE-S, but not the BFNE-R. These results suggest that standard scoring of the BFNE may not be optimal for patients with social anxiety disorder.

The Social Appearance Anxiety Scale (SAAS) was created to measure anxiety about being negatively evaluated by others because of one's overall appearance, including body shape. This study examined the psychometric properties of the SAAS in three large samples of undergraduate students (respective ns = 512, 853, and 541). The SAAS demonstrated a unifactorial structure with high test-retest reliability and internal consistency. The SAAS was positively associated with measures of social anxiety. The SAAS was also related to greater disparity between perceived, actual, and ideal physical attributes, beliefs that one's appearance is inherently flawed and socially unacceptable and that being unattractive is socially deleterious, feelings of unattractiveness, emphasis on appearance and its maintenance, and a preoccupation with being overweight. It was a unique predictor of social anxiety above and beyond negative body image indicators. Findings suggest that the SAAS is a psychometrically valid measure of social anxiety regarding one's overall appearance.

Improvements in life expectancy and quality of life for HIV-positive women coupled with reduced vertical transmission will likely lead numerous HIV-positive women to consider becoming pregnant. In order to clarify the demand, and aid with appropriate health services planning for this population, our study aims to assess the fertility desires and intentions of HIV-positive women of reproductive age living in Ontario, Canada. A cross-sectional study with recruitment stratified to match the geographic distribution of HIV-positive women of reproductive age (18–52) living in Ontario was carried out. Women were recruited from 38 sites between October 2007 and April 2009 and invited to complete a 189-item self-administered survey entitled “The HIV Pregnancy Planning Questionnaire” designed to assess fertility desires, intentions and actions. Logistic regression models were fit to calculate unadjusted and adjusted odds ratios of significant predictors of fertility intentions. The median age of the 490 participating HIV-positive women was 38 (IQR, 32–43) and 61%, 52%, 47% and 74% were born outside of Canada, living in Toronto, of African ethnicity and currently on antiretroviral therapy, respectively. Of total respondents, 69% (95% CI, 64%–73%) desired to give birth and 57% (95% CI, 53%–62%) intended to give birth in the future. In the multivariable model, the significant predictors of fertility intentions were: younger age (age<40) (p<0.0001), African ethnicity (p<0.0001), living in Toronto (p = 0.002), and a lower number of lifetime births (p = 0.02). The proportions of HIV-positive women of reproductive age living in Ontario desiring and intending pregnancy were higher than reported in earlier North American studies. Proportions were more similar to those reported from African populations. Healthcare providers and policy makers need to consider increasing services and support for pregnancy planning for HIV-positive women. This may be particularly significant in jurisdictions with high levels of African immigration.
