We studied the association of once-daily dosing with self-reported adherence among participants of the Ontario Cohort Study who were currently taking ART and who had completed a 90-min interviewer-administered questionnaire. Suboptimal adherence was defined as missing ≥1 dose of ART in the 4 days prior to the interview. Participants ( n = 779) were 85% male, 69% men having sex with men, 67% white, median age 48 years (IQR 42-54), median years of ART 9 (IQR 5-13) and median CD4 count 463 cells/mm (IQR 320-638). Fifteen percent of participants reported suboptimal adherence in the 4 days prior to the interview. In a multivariable logistic regression model, participants on once daily regimens were half as likely to miss a dose during the 4 days prior to the interview. Other independent correlates of suboptimal adherence were younger age, lower positive social interaction and increased frequency of consuming > 6 alcoholic drinks on one occasion.

Same-sex practices are stigmatized in much of sub-Saharan Africa. Cross-sectional relationships between discrimination, access to and use of health care services, and HIV knowledge among men who have sex with men (MSM) were assessed in Malawi, Namibia, and Botswana. A survey and HIV screening were used to explore these variables and the prevalence of HIV. Overall, 19% of men screened positive for HIV infection. Ninety-three percent knew HIV is transmitted through anal sex with men, however, only 67% had ever received information of how to prevent this transmission. Few (17%) reported ever disclosing same sex practices to a health professional and 19% reported ever being afraid to seek health care. Men reported ever been denied health care services (5%) and 21% had ever been blackmailed because of their sexuality. Strong associations were observed between experiences of discrimination and fear of seeking health care services. Characterizing the relationship between stigma and health care seeking practices and attitudes can inform the development and implementation of HIV interventions for African MSM.

The objective of this study was to describe the social networks of people living with HIV/AIDS (PLHA) and explore the implications social network characteristics might have for mobilizing PLHA as prevention agents. Thirty-nine PLHA attending an HIV clinic in Kampala, Uganda provided information on themselves and on 20 network members. Based on these data, descriptive statistics for social network composition and structure were calculated. Research questions relating these network characteristics to treatment-related variables such as time since diagnosis, ART status, and time on ART were investigated. Analyses reveal that, in general, network members know the PLHA's status, are trusted, provide advice and support, and are well-connected to each other. Network features (e.g., proportion of individuals who know the PLHA's status) are related to the previously mentioned treatment variables. Findings suggest that PLHA surround themselves with a social context that enables PLHA to feel fairly protected and supported if they choose to discuss HIV and prevention. With respect to treatment, those on ART may be better prepared to act as prevention advocates. [ABSTRACT FROM AUTHOR]

Fatigue is one of the most common and debilitating symptoms experienced by HIV-infected people. We report the results of our longitudinal analysis of physiological and psychosocial factors that were thought to predict changes in HIV-related fatigue in 128 participants over a 1-year period, in an effort to sort out the complex interplay among a comprehensive set of physiological and psychosocial variables. Physiological measures included hepatic function (aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase, alkaline phosphatase, total bilirubin, hepatitis C status), thyroid function (thyroid stimulating hormone, thyroxine), HIV viral load, immunologic function (CD4, CD8, CD4/CD8 ratio, CD16, CD8CD38), gonadal function (testosterone, dehydroepiandrosterone), hematologic function (hemoglobin, hematocrit, serum erythropoietin), and cellular injury (lactic acid). Psychosocial measures included childhood and adult trauma, anxiety, depression, social support, stressful life events, and post-traumatic stress disorder (PTSD). Unemployment, not being on antiretroviral therapy, having fewer years since HIV diagnosis, more childhood trauma, more stressful life events, less social support, and more psychological distress (e.g., PTSD, anxiety and depression) put HIV-infected persons at risk for greater fatigue intensity and fatigue-related impairment in functioning during 1-year follow-up. Physiological variables did not predict greater fatigue. Stressful life events had both direct and indirect effects on fatigue. [ABSTRACT FROM AUTHOR]
