Use of dietary supplements among people living with HIV/AIDS is associated with vulnerability to medical misinformation on the internet

<p>Abstract</p> <p>Background</p> <p>Use of dietary supplements is common among people living with HIV/AIDS. Because dietary supplements are used in the context of other health behaviors, they may have direct and indirect health benefits. However, supplements may also be associated with vulnerability to medical misinformation and unfounded health claims. We examined use of dietary supplements among people living with HIV/AIDS (PLWH) and the association between use of dietary supplements and believing medical misinformation.</p> <p>Methods</p> <p>A convenience sample of 268 men and 76 women living with HIV was recruited from AIDS services and clinics in Atlanta, GA. Participants completed measures of demographic and health characteristics, dietary supplement use, beliefs about dietary supplements, internet use, and an internet evaluation task designed to assess vulnerability to medical misinformation.</p> <p>Results</p> <p>One out of four PLWH currently used at least one dietary supplement product excluding vitamins. Dietary supplement use was associated with higher education and greater use of the internet for health-related information. Dietary supplement users also endorsed greater believability and trust in unfounded claims for HIV cures.</p> <p>Conclusions</p> <p>Dietary supplement use is common among PLWH and is associated with a broad array of health information seeking behaviors. Interventions are needed to reduce the vulnerability of PLWH, particularly dietary supplement users, to medical misinformation propagated on the internet.</p

Associations of poverty, substance use, and HIV transmission risk behaviors in three South African communities

The majority of the world's HIV infections occur in communities ravished by poverty. Although HIV/AIDS and poverty are inextricably linked, there are few studies of how poverty-related stressors contribute to HIV risk behavior practices. In this study, surveys were conducted in three South African communities that varied by race and socio-economic conditions: people living in an impoverished African township (N=499); an economically impoverished but well infrastructured racially integrating township (N=995); and urban non-impoverished neighborhoods (N=678). Results showed that HIV/AIDS risks were closely related to experiences of poor education, unemployment, discrimination, violence, and crime. Although poverty-related stressors were associated with a history of alcohol and drug use, substance use did not moderate the association between poverty-related stressors and HIV risk behaviors. The findings suggest that HIV prevention strategies should not treat AIDS as a singled out social problem independent of other social ills.HIV/AIDS South Africa Poverty Risk behavior

Treatment Outcomes Among People Living With HIV Who Are Food Insecure and Prescribed Antiretrovirals Taken With Food

Background: Food insecurity is a known barrier to medication adherence among people living with HIV. Antiretroviral therapies (ART) that require food likely pose added challenges to patients who do not have reliable access to food. This study examines the health implications of prescribing ART that requires food to patients who are food insecure. Method: A community sample of 538 men and 221 women currently taking ART to treat their HIV infection completed computerized interviews, biweekly unannounced pill count adherence assessments, and obtained their HIV RNA (viral load) and CD4 cell count from medical records. Results: Sixty-three percent of participants experienced at least 1 indicator of food insecurity during the previous month, of which 274 (57%) were prescribed an ART regimen that requires food. Among participants who were food insecure, individuals taking ART requiring food indicated significantly greater HIV symptoms, had lower CD4 cell counts, and poorer HIV suppression. For participants who were food secure, those taking ART that requires food were significantly less adherent than those whose ART regimen does not require food. Conclusions: People living with HIV who experience food insecurity are significantly more likely to be prescribed ART regimens that require food and experience poorer treatment outcomes. Determination of optimal ART regimens should take patient access to food into account and treatment guidelines should explicitly highlight the importance of food access in selecting ART regimens
