Problem drinking and associated factors in older adults in South Africa
Objective: Alcohol abuse poses special risks for increased morbidity and mortality among older adults. Little attention has focused on assessing alcohol use and associated factors among older adults in transitional societies such as South Africa. This study aimed to determine the prevalence of alcohol use and associated factors in older South Africans who participated in the Study of Global Ageing and Adults Health (SAGE) in 2008. Method: We conducted a national population-based cross-sectional study with a sample of 3840 aged 50 years or older in South Africa in 2008. In this study we analysed data from all 2144 participants who were over 60 years old. The questionnaire included socio-demographic characteristics, alcohol intake as well as comorbidity. Risky drinking was defined in two ways: heavy drinkers (>7 drinks/week) and binge drinkers (>3 drinks/one occasion/week).Results: Four percent of participants reported heavy drinking and 3.7% binge drinking. Male gender (Odds Ratio (OR) =3.79, Confidence Interval (CI) =1.38-10.37) and white population group (OR=3.01, CI=1.31-6.89) were associated with risky drinking in multivariate analysis; as well as tobacco use (OR=5.25, CI=2.20-12.52) and not being obese (OR=0.14, CI=0.05-0.35). Hypertension, diabetes and depression were not associated. Conclusion: This study reveals moderate rates of risky drinking among older adults (60 years and more) in South Africa that puts them at risk of morbidity. Alcohol problems among older adults are commonly under-recognized, indicating a need for health care worker intervention.Keywords: Alcohol abuse; Prevalence; Risk factors; Older adults; South Afric
Rewriting the narrative of the epidemiology of HIV in sub-Saharan Africa
The fight against HIV remains complicated with contracting donor resources and high burden of HIV among reproductive age adults still often limiting independent economic development. In the widespread HIV epidemics of sub-Saharan Africa (SSA), it is proposed that key populations with specific HIV acquisition and transmission risk factors, such as men who have sex with men (MSM), female sex workers (FSW), and people who use drugs (PUD), are less relevant because HIV transmission is sustained in the general population with average HIV acquisition and transmission risks. However, the understanding that key populations are less relevant in the epidemics of Africa is based on the surveillance system from which these populations are mostly excluded. Outside of SSA, the epidemics of HIV are generally concentrated in the same populations that are excluded from the primary HIV surveillance systems in SSA. The manuscripts included in this special issue present convincing data that FSW, MSM, and PUD carry disproportionate burdens of HIV wherever studied in SSA, are underrepresented in HIV programs and research, and require specific HIV prevention services. These manuscripts collectively suggest that the only effective path forward is one that transcends denial and stigma and focuses on systematically collecting data on all populations at risk for HIV. In addition, there is a need to move to a third generation of HIV surveillance as the current one inadvertently devalues HIV surveillance among key populations in the context of widespread HIV epidemics. Overall, the data reviewed here demonstrate that the dynamics of HIV in Africa are complex and achieving an AIDS-free generation necessitates acceptance of that complexity in all HIV surveillance, research, and prevention, treatment, and care programs
Perceived HIV/AIDS impact among staff in tertiary institutions in the Eastern Cape, South Africa
A descriptive questionnaire-based study was undertaken among staff in tertiary institutions in the Eastern Cape Province.The objective of the study was to explore perceived HIV/AIDS impact on duties at work, staff morale, job satisfaction and workload among a proportionate sample of 872 employees in eight randomly selected tertiary institutions.The results of the study showed that HIV/AIDS impacts negatively on duties at work, lowers staff morale and increases staff workload. Keywords: HIV,AIDS, impact, tertiary institutions, South Africa.RÉSUMÉUne étude basée sur un questionnaire descriptif a été faite parmi le personnel des établissements d'enseignement supérieur de la province du Cap de l'Est. Le but de cette étude fut d'étudier l'impact du VIH/SIDA perçu sur les fonctions à remplir dans le lieu de travail, le moral du personnel, la satisfaction professionnelle et la charge de travail parmi un échantillon proportionnel de 872 employés de huit établissements sélectionnés au hasard. Les résultats de cette étude ont montré que le VIH/SIDA a un impact négatif sur les fonctions à remplir dans le lieu de travail, qu'il réduit le moral du personnel et qu'il augmente la charge de travail.

Assessing missed opportunities for the prevention of mother-to-child HIV transmission in an Eastern Cape local service area
Background. Prevention of new HIV infections is a critical imperative for South Africa; the prevention of mother-to-child transmission (PMTCT) is one of the most efficacious HIV prevention interventions.Objective. Assessment of a PMTCT programme to determine missed opportunities.Setting. The Kouga local service area (LSA), bordering Nelson Mandela Bay Municipality (Port Elizabeth) in the Eastern Cape.Methods. An assessment was conducted in 2007 before implementing technical support for strengthening the PMTCT programme, including: interviews with 20 PMTCT managers, 4 maternity staff and 27 other health workers on service provision, management, infrastructure, human resources and the health information system; 296 antenatal clinic users on their service perceptions; 70 HIV-positive women onHIV knowledge, infant feeding, coping, support and service perceptions; 8 representatives from community organisations and 101 traditional health practitioners (THPs). Observations were conducted during site visits to health facilities, and the District Health Information System (DHIS) data were reviewed.Results. Staff had high levels of awareness of HIV policies and most had received some relevant training. Nevirapine uptake varied by clinic, with an average of 56%. There were many missed opportunities for PMTCT, with 67% of pregnant women tested for HIV and only 43% of antenatal care attendees tested during a previous pregnancy. Only 6% of HIV-positive women reported support group participation.Conclusions. Reducing missed opportunities for PMTCT requires strengthening of the formal health sector, intersectoral liaison, and greater community support. Priority areas that require strengthening in the formal health sector include HIV counselling and testing; family planning and nutrition counselling; infant follow-up; human resources; and monitoring and evaluation
Prevalence, circumstances and consequences of non-fatal road traffi c injuries and other bodily injuries among older people in China, Ghana, India, Mexico, Russia and South Africa
Unintentional injuries are one of the main contributors to mortality and disability in elderly populations in low- and middle-income countries. The aim of this study was to examine the annual road traffic and other bodily (not including falls) injury prevalence and associated risk factors among older adults across six lower and upper middle-income countries. A cross- sectional survey involving face-to-face household interviews were conducted in China (n=13,177), Ghana (n=4305), India (n=6560), Mexico (n=2318), the Russian Federation (n=3938) and South Africa (n=3840), resulting in population-based cohorts of persons aged 50+ years. Measures included questions on injury, self-rated visual difficulties, alcohol use, depression treatment, sleeping problems, self-reported health status, and vision assessment using LogMAR (logarithm of Minimum Angle of Resolution) eye charts. It comprises rows of letters and is used to measure visual acuity. Results indicate that the overall annual non-fatal road traffic injury prevalence was 2.0% and for other bodily injury 2.1% (not including falls) across the six countries. The multivariate logistic regression analysis found that residing in a rural area, taking medications or other treatment for depression in the past 12 months and having a sleeping problem were associated with road traffic injury, while younger age, residing in a rural area, hazardous or harmful alcohol use and having a sleeping problem were associated with other bodily injury. Visual impairment was not associated with prevalence of road traffic injuries. This study provides the burden of non-fatal road traffic injury and other bodily injury and their associated risk factors across the six countries’ studies. The findings of this study improves the understanding of non-fatal road traffic injury and other bodily injury upon which policy makers, programme developers and researchers in public health can design strategic interventions to reduce these preventable injuries as well as improve safety associated with unintentional injuries.Keywords: injury, traffic, ageing, China, Ghana, India, Mexico, Russian Federation, South Africa
Qualitative Environmental Health Research: An Analysis of the Literature, 1991-2008
BACKGROUND. Recent articles have advocated for the use of qualitative methods in environmental health research. Qualitative research uses nonnumeric data to understand people's opinions, motives, understanding, and beliefs about events or phenomena. OBJECTIVE. In this analysis of the literature, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. DATA SOURCES. A primary search on ISI Web of Knowledge/Web of Science for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Inclusion and exclusion criteria are described. DATA EXTRACTION. Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. DATA SYNTHESIS. Ninety-one articles met inclusion criteria. These articles were published in 58 different journals, with a maximum of eight for a single journal. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health, with most studies relying on one-on-one interviews. Details of the analyses were absent from a large number of studies. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. DISCUSSION AND CONCLUSIONS. Qualitative data are published in traditionally quantitative environmental health studies to a limited extent. However, this analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.National Institute of Environmental Health Sciences (R25 ES012084, P42ES007381
Lagged acute respiratory outcomes among children related to ambient pollutant exposure in a high exposure setting in South Africa
BACKGROUND : Acute ambient air pollution impacts on the respiratory health of children may be lagged across time. We determined
the short-term lagged effects of particulate matter (PM2.5), sulphur dioxide (SO2), and oxides of nitrogen (NOx) on the respiratory
health of children living in low-income communities.
METHODS : A school-based study was conducted using a repeated measures design, across summer and winter, in four schools in
each of four suburbs in the Vaal Triangle, South Africa. Data for PM2.5, NOx, and SO2 were obtained from monitoring stations within
close proximity of the schools. Over 10 school days in each phase, grade 4 children completed a symptoms log and lung function
tests. Parents completed a child respiratory questionnaire. Generalized estimation equations models adjusted for covariates of interest
in relation to lung function outcomes and air pollutants including lag effects of 1–5 days.
RESULTS : Daily PM2.5, NOx, and SO2 median concentration levels were frequently higher than international standards. Among the 280
child participants (mean age 9 years), the prevalence of symptoms based on probable asthma was 9.6%. There was a consistent
increased pollutant-related risk for respiratory symptoms, except for NOx and shortness of breath. Lung function, associated with
pollutant fluctuations across the different lags, was most pronounced for peak expiratory flow rate (PEFR) for PM2.5 and SO2. A preceding
5-day average SO2 exposure had the largest loss (7.5 L/minute) in PEFR.
CONCLUSIONS : Lagged declines in daily lung function and increased odds of having respiratory symptoms were related to increases
in PM2.5 and SO2 among a school-based sample of children.The South African National Department of Forestry, Fisheries and the Environment.https://journals.lww.com/environepidem/Pages/default.aspxam2023Geography, Geoinformatics and Meteorolog
Mapping the number of female sex workers in countries across sub- Saharan Africa
Female sex workers (FSW) are affected by individual, network, and structural risks, making them vulnerable to poor health and well-being. HIV prevention strategies and local community-based programs can rely on estimates of the number of FSW to plan and implement differentiated HIV prevention and treatment services. However, there are limited systematic assessments of the number of FSW in countries across sub-Saharan Africa to facilitate the identification of prevention and treatment gaps. Here we provide estimated population sizes of FSW and the corresponding uncertainties for almost all sub-national areas in sub-Saharan Africa. We first performed a literature review of FSW size estimates and then developed a Bayesian hierarchical model to synthesize these size estimates, resolving competing size estimates in the same area and producing estimates in areas without any data. We estimated that there are 2.5 million (95% uncertainty interval 1.9 to 3.1) FSW aged 15 to 49 in sub-Saharan Africa. This represents a proportion as percent of all women of childbearing age of 1.1% (95% uncertainty interval 0.8 to 1.3%). The analyses further revealed substantial differences between the proportions of FSW among adult females at the sub-national level and studied the relationship between these heterogeneities and many predictors. Ultimately, achieving the vision of no new HIV infections by 2030 necessitates dramatic improvements in our delivery of evidence-based services for sex workers across sub-Saharan Africa
