RESUMO

HIV testing and antiretroviral therapy (ART) remain critical for curbing the spread of HIV/AIDS, but stigma can impede access to these services. Using data from the Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI), we used a multivariable logistic regression to examine the correlation between HIV-related stigma, HIV testing and ART uptake in older adults. We used four questions to measure stigma, with three assessing social stigma (reflecting social distancing preferences) and one assessing anticipated stigma (disclosure concern). We combined the three social stigma questions to generate a social stigma score ranging from 0 to 3, with higher scores indicating higher stigma. Anticipated stigma was prevalent 85% (95% CI 0.84-0.86), and social stigma was also frequent 25% (95% CI 0.24-0.27). Higher social stigma scores correlated with decreased HIV testing for all participants with social stigma. Compared to those with a score of 0, odds of testing decreased with higher stigma scores (OR = 0.66, 95% CI 0.53-0.81, p = 0.000) for a score of 1 and (OR = 0.56, 95% CI 0.38-0.83, p = 0.004) for a score of 3. ART uptake also decreased with higher social stigma scores among people living with HIV (PLWH), although it was significant for those with a score of 2 (OR = 0.41, 95% CI 0.19-0.87, p = 0.020). These findings emphasize that HIV-related stigma hampers testing and ART uptake among older adults in rural South Africa. Addressing stigma is crucial for improving testing rates, early diagnosis, and treatment initiation among the older population and achieving UNAIDS 95-95-95 targets.

RESUMO

OBJECTIVE: More than one in four adults over 40 years with HIV in South Africa are unaware of their status and not receiving antiretroviral therapy (ART). HIV self-testing may offer a powerful approach to closing this gap for aging adults. Here, we report the results of a randomized comparative effectiveness trial of three different home-based HIV testing strategies for middle-aged and older adults in rural South Africa. DESIGN: Two thousand nine hundred and sixty-three individuals in the 'Health and Ageing in Africa: a Longitudinal Study of an INDEPTH Community in South Africa (HAALSI)' cohort study were randomized 1 : 1 : 1 to one of three types of home-based and home-delivered HIV testing modalities: rapid testing with counseling; self-testing, and both rapid testing with counselling and self-testing. METHOD: In OLS regression analyses, we estimated the treatment effects on HIV testing and HIV testing frequency at about 1 year after delivery. Finally, we assessed the potential adverse effects of these strategies on the secondary outcomes of depressive symptom as assessed by the CESD-20, linkage to care, and risky sexual behavior. RESULTS: There were no significant differences in HIV testing uptake or testing frequency across groups. However, respondents in the self-testing treatment arms were more likely to shift from testing at home and a facility [self-testing (HIVST), -8 percentage points (pp); 95% confidence interval (CI) -14 to -2 pp; self-testing plus rapid testing and counselling (ST+RT+C); -9 pp, 95% CI -15 to -3 pp] to testing only at home (HIVST 5 pp; 95% CI 2 to 9 pp; ST+RT+C: 5 pp, 95% CI 1 to 9 pp) - suggesting a revealed preference for self-testing in this population. We also found no adverse effects of this strategy on linkage to care for HIV and common comorbidities, recent sexual partners, or condom use. Finally, those in the self-testing only arm had significantly decreased depressive symptom scores by 0.58 points (95% CI -1.16 to -0.01). CONCLUSION: We find HIV self-testing to be a well tolerated and seemingly preferred home-based testing option for middle-aged and older adults in rural South Africa. This approach should be expanded to achieve the UNAIDS 95-95-95 targets.

RESUMO

INTRODUCTION: Despite rapid population aging, there are currently limited data on the incidence of aging-related cognitive impairment in sub-Saharan Africa. We aimed to determine the incidence of cognitive impairment and its distribution across key demographic, social, and health-related factors among older adults in rural South Africa. METHODS: Data were from in-person interviews with 3,856 adults aged ≥40 who were free from cognitive impairment at baseline in the population-representative cohort, "Health and Aging in Africa: a Longitudinal Study of an INDEPTH Community in South Africa" (HAALSI), in Agincourt sub-district, Mpumalanga province, South Africa (2014-19). Cognitive impairment was defined as scoring <1.5 standard deviations below the mean of the baseline distribution of orientation and episodic memory scores. Incidence rates and rate ratios for cognitive impairment were estimated according to key demographic, social, and health-related factors, adjusted for age, sex/gender, and country of birth. RESULTS: The incidence of cognitive impairment was 25.7/1,000 person-years (PY; 95% confidence interval [CI]: 23.0-28.8), weighted for mortality (12%) and attrition (6%) over the 3.5-year mean follow-up (range: 1.5-4.8 years). Incidence increased with age, from 8.9/1,000 PY (95% CI: 5.2-16.8) among those aged 40-44 to 93.5/1,000 PY (95% CI: 75.9-116.3) among those aged 80+, and age-specific risks were similar by sex/gender. Incidence was strongly associated with formal education and literacy, as well as marital status, household assets, employment, and alcohol consumption but not with history of smoking, hypertension, stroke, angina, heart attack, diabetes, or prevalent HIV. CONCLUSIONS: This study presents some of the first incidence rate estimates for aging-related cognitive impairment in rural South Africa. Social disparities in incident cognitive impairment rates were apparent in patterns similar to those observed in many high-income countries.

RESUMO

BACKGROUND: The Center for Epidemiologic Studies-Depression (CES-D) scale is a widely used measure of depressive symptoms, but its construct validity has not been adequately assessed in sub-Saharan Africa. This study validates the CES-D among an aging Shangaan-speaking and predominantly Black African sample in rural South Africa, with a special emphasis on gender differences. METHODS: An 8-item CES-D scale was administered in Shangaan to 5059 respondents, aged 40+ years, residing in Agincourt, South Africa. We used Cronbach's alpha and exploratory and confirmatory factor analysis to examine and confirm dimensionality of the CES-D scale. Differential endorsement of CES-D items by gender were assessed using the Mantel-Haenszel (MH) odds ratio test. RESULTS: Reliability of the CES-D scale differed by gender with women reporting higher internal consistency on items than men. A two-factor solution was retained and confirmed representing two latent factors: (1) Negative Affect (six items) and (2) Diminished Positive Affect (two items). MH results showed that men exhibited significantly higher odds of putting an effort in everything that they did (OR: 1.33, 95% CI: 1.15-1.54) and lower odds of feeling depressed (OR: 0.71, 95% CI: 0.56-0.89) and having restless sleep (OR: 0.67, 95% CI:0.58-0.77) than women. LIMITATIONS: Analyses were limited to a dichotomous, short form of the CES-D, a self-reported population-based measure. CONCLUSION: Aging Black Africans differ in endorsing affective and somatic items on the CES-D scale by gender, which may lead to skewed population-level estimates of depression in key subpopulations. These findings highlight the importance of continued research disentangling cross-cultural and gendered nuances of depression measurements.

RESUMO

OBJECTIVES: The study aimed to explore the factors facilitating and inhibiting female condom use among female university students in South Africa. METHODS: This qualitative study drew on 15 individual, in-depth interviews with female university students in Durban, South Africa. RESULTS: The results of the study highlight several factors that facilitate and inhibit female condom use. Protection from sexually transmitted infections (including HIV/AIDS) and prevention of pregnancy facilitated use of the device among female students. In addition, students expressed positive attitudes towards the female condom and preferred it to hormonal contraceptives because it offered them dual protection. Absence of side effects and greater power and autonomy to initiate safer sex were other factors that facilitated use. Inadequate availability, partner objection, stigma, insertion difficulties and lack of awareness served as significant barriers to consistent female condom use. CONCLUSIONS: Although the female condom can protect female students from infections and pregnancy, there are several barriers to its use. Interventions should aim to increase availability of the female condom, and male involvement should be increased to facilitate consistent use of the method.
