Births in Low- and Middle-Income Countries during the Covid-19 Pandemic
The impact of the COVID-19 pandemic on fertility in low- and middle-income countries (LMICs) remains a subject of much speculation. This article reports monthly birth registration data from 18 United Nations Population Fund (UNFPA) program countries, all predominantly LMICs, both before and after the onset of the COVID pandemic. Despite disruptions in family planning services in many of these countries during the early months of the pandemic, mon…
A risk measurement tool for targeted HIV prevention measures amongst young pregnant and lactating women in South Africa
The optimal model to be used as a possible risk scoring tool to allow for early identification of those pregnant/lactating women most at-risk of HIV acquisition included both statistically as well as clinically meaningful risk factors. A field-based study is needed to test and validate the effectiveness of this targeted approach
Impact of breastfeeding, maternal antiretroviral treatment and health service factors on 18-month vertical transmission of HIV and HIV-free survival
Background We analysed the impact of breastfeeding, antiretroviral drugs and health service factors on cumulative (6 weeks to 18 months) vertical transmission of HIV (MTCT) and ‘MTCT-or-death’, in South Africa, and compared estimates with global impact criteria to validate MTCT elimination: (1) Methods 9120 infants aged 6 weeks were enrolled in a nationally representative survey. Of 2811 HIV-exposed uninfected infants (HEU), 2644 enrolled into fo…
Gender difference in trends in healthy life expectancy in 2005-2012 for adults aged 50 years and older in South Africa
Data characterizing older people’s life expectancy by good or poor health is important for policy and fiscal planning. This study aims to examine trends and investigate gender differences in healthy life expectancy (HLE) for older people in South Africa for the period 2005–2012. Using data from three repeated cross-sectional surveys conducted in 2005, 2008, and 2012, we applied a self-rated health measure to estimating HLE. The Sullivan method wa…
Completeness of patient-held records
BACKGROUND: Continuity of care is important for child well-being in all settings where postnatal retention of mother-infant pairs in care remains a challenge. This analysis reports on completeness of patient-held infant Road to Health Booklets (RtHBs), amongst HIV exposed and unexposed infants during the first two years after the RtHB was launched country-wide in South Africa. METHODS: Secondary data were analysed from two nationally representati…
Uptake and predictors of early postnatal follow–up care amongst mother–baby pairs in South Africa
BACKGROUND: Achieving World Health Organization (WHO) recommendations for postnatal care (PNC) within the first few weeks of life is vital to eliminating early mother-to-child transmission of HIV (MTCT) and improving infant health. Almost half of the annual global deaths among children under five occur during the first six weeks of life. This study aims to identify uptake of three PNC visits within the first six weeks of life as recommended by WH…
Predictors of multiple concurrent and multiple sexual partnerships among male and female youth aged 18–24 in South Africa
This study aimed to determine predictors of multiple concurrent and multiple sexual partnerships among South African male and female youth. Data were from a cross-sectional population-based household survey of 3 123 youths aged 18 to 24 years from four South African provinces (males = 53.6%, blacks = 97.8%). Results from a sub-sample of being sexually active in the past 12 months (n = 1787) indicate that 5.3% (7.1% in males and 3.1% in females) y…
Health status and years of sexually active life among older men and women in South Africa
Little is known about sexual activity in old age, particularly in Africa. The objective of this paper is to estimate years of sexually active life for older men and women, and examine the association between sexual activity and self-rated health status. Data were extracted from two large cross sectional HIV household surveys conducted in 2005 and 2012 in South Africa. The Sullivan method was used to estimate sexually active life expectancy, whils…
Self-reported prevalence of chronic non-communicable diseases and associated factors among older adults in South Africa
INTRODUCTION: Little is known about the prevalence and predictors of chronic non-communicable diseases (NCDs) of older adults in South Africa. This study aims to investigate the self-reported prevalences of major chronic NCDs and their predictors among older South Africans. METHODS: We conducted a national population-based cross-sectional survey with a sample of 3,840 individuals aged 50 years or above in South Africa in 2008. The outcome variabl…
Sociodemographic predictors of multiple non-communicable disease risk factors among older adults in South Africa
BACKGROUND AND OBJECTIVE: Unhealthy lifestyle behaviours are important risk factors of morbidity and mortality. This study aimed to explore the sociodemographic predictors of multiple non-communicable disease (NCD) risk factors experienced by elderly South Africans. METHODS: We conducted a national population-based cross-sectional survey with a sample of 3,840 individuals aged 50 years or above in South Africa in 2008. The outcome variable was th…
Self-rated health and associated factors among older South Africans
BACKGROUND: Population ageing has become significant in South African society, increasing the need to improve understandings of health and well-being among the aged. OBJECTIVE: To describe the self-reported ratings of overall health and functioning, and to identify factors associated with self-rated health among older South Africans. DESIGN: A national population-based cross-sectional survey, with a sample of 3,840 individuals aged 50 years and o…
Access to Opportunities and the Lovelife Programme Among Youth in South Africa
We evaluated the efficacy of a motivational and opportunity multimedia health promotion programme for young people: loveLife. Participants were 3123 youth from four of nine provinces of South Africa (mean age=20.5 years, SD=2.0, females=45.4%, the majority population group=91.5% Black African). They completed a number of measures on opportunities, value-add and motivation, individual factors, socioeconomic factors, health risk and exposure to lov…
Early Sexual Debut and Associated Risk Factors Among Male and Female Youth in South Africa
The aim of this study was to investigate the prevalence and correlates of early sexual debut among youth aged 18–24 in South Africa. In a cross-sectional population based survey 3123 youth were interviewed with a structured questionnaire in four provinces (Eastern Cape, Gauteng, KwaZulu-Natal and Mpumalanga). Data analysis was restricted to youth who reported ever having sex (N=2072). Multivariable logistic regression was used to examine the rela…
