Chronic disease, risk factors and disability in adults aged 50 and above living with and without HIV: findings from the Wellbeing of Older People Study in Uganda.
BACKGROUND: Data on the prevalence of chronic conditions, their risk factors, and their associations with disability in older people living with and without HIV are scarce in sub-Saharan Africa. OBJECTIVES: In older people living with and without HIV in sub-Saharan Africa: 1) to describe the prevalence of chronic conditions and their risk factors and 2) to draw attention to associations between chronic conditions and disability. METHODS: Cross-sectional individual-level survey data from people aged 50 years and over living with and without HIV were analyzed from three study sites in Uganda. Diagnoses of chronic conditions were made through self-report, and disability was determined using the WHO Disability Assessment Schedule (WHODAS). We used ordered logistic regression and calculated predicted probabilities to show differences in the prevalence of multiple chronic conditions across HIV status, age groups, and locality. We used linear regression to determine associations between chronic conditions and the WHODAS. RESULTS: In total, 471 participants were surveyed; about half the respondents were living with HIV. The prevalence of chronic obstructive pulmonary disease and eye problems (except for those aged 60-69 years) was higher in the HIV-positive participants and increased with age. The prevalence of diabetes and angina was higher in HIV-negative participants. The odds of having one or more compared with no chronic conditions were higher in women (OR 1.6, 95% CI 1.1-2.3) and in those aged 70 years and above (OR 2.1, 95% CI 1.2-3.6). Sleep problems (coefficient 14.2, 95% CI 7.3-21.0) and depression (coefficient 9.4, 95% CI 1.2-17.0) were strongly associated with higher disability scores. CONCLUSION: Chronic conditions are common in older adults and affect their functioning. Many of these conditions are not currently addressed by health services in Uganda. There is a need to revise health care policy and practice in Uganda to consider the health needs of older people, particularly as the numbers of people living into older age with HIV and other chronic conditions are increasing
The effects of HIV and systolic blood pressure on mortality risk in rural South Africa, 2010-2019: a data note
Objectives: South Africa is experiencing both HIV and hypertension epidemics. Data were compiled for a study to identify effects of HIV and high systolic blood pressure on mortality risk among people aged 40-plus in a rural South African area experiencing high prevalence of both conditions. We aim to release the replication data set for this study.
Data description: The research data comes from the 2010-11 Ha Nakekela (We Care) population-based survey nested in the Agincourt Health and socio-Demographic Surveillance System (AHDSS) located in the northeast region of South Africa. An age-sex-stratified probability sample was drawn from the AHDSS. The public data set includes information on individual socioeconomic characteristics and measures of HIV status and blood pressure for participants aged 40-plus by 2019. The AHDSS, through its annual surveillance, provided mortality data for nine years subsequent to the survey. These data were converted to person-year observations and linked to the individual-level survey data using participants’ AHDSS census identifier. The data can be used to replicate Houle et al. (2022) — which used discrete-time event history models stratified by sex to assess differential mortality risks according to Ha Nakekela measures of HIV-infection, HIV-1 RNA viral load, and systolic blood pressure
Social engagement and survival in people aged 50 years and over living with HIV and without HIV in Uganda: a prospective cohort study.
This study examined the association between social engagement and survival in people with or without HIV aged 50 years and over in Uganda. We analysed two waves of a survey from two sites in Uganda to assess predictors of mortality between waves. The first wave was conducted between 2009 and 2010 while the second wave was conducted between 2012 and 2013. A standardised questionnaire adapted from the World Health Organization study on global AGEing and adult health (SAGE) was administered through face-to-face interviews at both survey waves. Cox proportional hazards models and Nelson-Aalen cumulative hazards functions were used to investigate associations between the strength of participants' social ties, using distance and intimacy metrics, and their social engagement with mortality between waves. Of the original 510 participants, 63 (12.3%) died between waves. Being more socially engaged and able to provide in-kind or financial contributions to family or friends were protective. After adjusting for covariates neither social tie measure was predictive of mortality. There were no significant differences in social engagement and survival by HIV status. Further research is needed in African settings on the relationship between social relationships and subsequent mortality in older adults to assess if improved social relationships could moderate mortality
Clusters of HIV risk and protective sexual behaviors in Agincourt, Rural South Africa; Findings from the Ha Nakekela population-based study of ages 15 and older
Understanding how sexual behaviors cluster in distinct population subgroups along the life course is critical for effective targeting and tailoring of HIV prevention messaging and intervention activities. We examined interrelatedness of sexual behaviors and variation between men and women across a wide age range in a rural South African setting with a high HIV burden. Data come from the Ha Nakekela population-based survey of people aged 15-85-plus drawn from the Agincourt Health and Socio-Demographic Surveillance System. We used latent class analysis of six sexual behavior indicators to identify distinct subgroup sexual behavior clusters. We then examined associations between class membership and sociodemographic and other behavioral risk factors and assessed the accuracy of a reduced set of sexual behavior indicators to classify individuals into latent classes. We identified three sexual behavior classes: (1) single with consistent protective behaviors; (2) risky behaviors; and (3) in union with lack of protective behaviors. Patterns of sexual behaviors varied by gender. Class membership was also associated with age, HIV status, nationality, and alcohol use. With only two sexual behavior indicators (union status and multiple sexual partners), individuals were accurately assigned to their most likely predicted class. There were distinct multidimensional sexual behavior clusters in population subgroups that varied by sex, age, and HIV status. In this population, only two brief questions were needed to classify individuals into risk classes. Replication in other situations is needed to confirm these findings.We are grateful for funding support from: the US National

“I attend at Vanguard and I attend here as well”: barriers to accessing healthcare services among older South Africans with HIV and non-communicable diseases
Background: HIV and non-communicable disease (NCD) are syndemic within sub-Saharan Africa especially among
older persons. The two epidemics interact with one another within a context of poverty, inequality and inequitable
access to healthcare resulting in an increase in those aged 50 and older living with HIV and experiencing an NCD comorbidity.
We explore the challenges of navigating healthcare for older persons living with HIV and NCD co-morbidity.
Methods: In-depth semi-structured interviews were conducted with a small sample of older persons living with HIV
(OPLWH). The perspectives of key informants were also sought to triangulate the evidence of OPLWH. The research
took place in two communities on the outskirts of Cape Town, South Africa. All interviews were conducted by a
trained interviewer and transcribed and translated for analysis. Thematic content analysis guided data analysis.
Results: OPLWH experienced an HIV-NCD syndemic. Our respondents sought care and accessed treatment for both
HIV and other chronic (and acute) conditions, though these services were provided at different health facilities or by
different health providers. Through the syndemic theory, it is possible to observe that OPLWH and NCDs face a
number of physical and structural barriers to accessing the healthcare system. These barriers are compounded by
separate appointments and spaces for each condition. These difficulties can exacerbate the impact of their ill-health
and perpetuate structural vulnerabilities. Despite policy changes towards integrated care, this is not the experience of
OPLWH in these communities.
Conclusions: The population living with HIV is aging increasing the likelihood that those living with HIV will also be
living with other chronic conditions including NCDs. Thus, it is essential that health policy address this basic need to
integrate HIV and NCD care
Numbers and narratives: Making sense of gender and context in rural Malawi
The 1994 International Conference on Population and Development prompted demographers and policy makers to focus research on the situation of women, particularly in Third World nations. Through accurate measurement, understanding and improvement of women\u27s situation, researchers and policy makers believe other desirable outcomes will result. In particular, such improvements are expected to enhance women\u27s control over their own reproductive and sexual health. Improving women\u27s control is hypothesized to translate into reductions in fertility, increases in contraceptive use, and greater ability to negotiate safe sexual relations. The study of gender is relatively new to demography; thus, there is little agreement, however, about how to measure women\u27s situation, or how to interpret quantitative measures that are currently in vogue. I integrate qualitative and quantitative methodologies to better understand women\u27s situation and its relationship to sexual and reproductive health. My data come from two distinct regions of rural Malawi—the patrilineal North and the matrilineal South. I analyze the 1998 Malawi Diffusion and Ideational Change (MDIC) household survey; and supplement these data with semi-structured interviews I conducted in 2000 with 91 MDIC respondents. It is unclear whether women\u27s situation is more pertinent at the individual or societal level. Thus, I examine the quantitative data at the individual and regional levels. Using regression analysis, I explore individual-level and regional-level effects of women\u27s situation indicators on contraceptive use and worry about contracting HIV/AIDS. In addition, I compare the level of gender inequality in the two regions. In neither analysis do the women\u27s situation indicators have consistent or strong associations with the outcome variables in the expected direction. Thus, I turn to qualitative data to explain the quantitative inconsistencies. I draw on the qualitative data to evaluate the quantitative indicators of women\u27s situation-reviewing how respondents heard, interpreted, and answered the MDIC survey questions. In addition, the qualitative data become an inductive instrument uncovering the ways in which men and women in rural Malawi conceptualize women\u27s status, autonomy, and power. Finally, I suggest ways in which these local perceptions of women\u27s situation could be measured quantitatively in Malawi and more generally in sub-Saharan Africa in the future
``Taking care of my own blood'': Older women's relationships to their households in rural South Africa
Timing of Most Recent Health Care Visit by Older People Living With and Without HIV.
The objective of this article is to document factors associated with the recency of health-care service utilization by people aged 50 years and over living with and without HIV in Uganda. A survey was conducted with 510 Ugandans aged 50 and older, living with and without HIV. The survey included information on sociodemographic characteristics, health state, self-reported chronic conditions, and timing of most recent visit to a health-care facility (time since last visit [TSLV]). We use ordinal logistic regression to identify independent factors associated TSLV. Independent factors associated with TSLV (>6 months) include age, OR = 2.40 [95% CI 1.08-5.37] for those aged 80 years and above, urban respondents, OR = 0.6 [95%CI 0.38-0.94], HIV-positive respondents, OR = 0.33 [95%CI 0.18-0.59], and better health. To understand the meaning of these finding, further investigation should examine (a) how best to define and measure older persons' health-care service needs and (b) older persons' decision-making processes around the timing of their access to health-care facilities
