Fragmented prevention in rural South Africa
BACKGROUND: Non-communicable diseases (NCDs) disproportionately affect rural South Africans due to limited healthcare access and delayed diagnoses. Biokineticists, experts in clinical exercise therapy, can aid in the early detection and prevention of NCDs, but their integration into primary healthcare remains limited. OBJECTIVE: To explore Biokineticists' perspectives on their role in early NCD detection and prevention in rural South Africa, alon…
Bridging gaps in community cancer care
BACKGROUND: Despite the rising cancer burden in Soweto, South Africa and the recognized role of Traditional Health Practitioners (THPs) in the pluralistic health system, their role in cancer care remains underexplored. This study provides novel insights into THPs' understanding of cancer and their potential contribution to community awareness and early detection within complex sociocultural and health system contexts. OBJECTIVE: To explore THPs p…
Cash transfers targeting adolescent wellbeing
Creating healthy food environments is central to improving adolescent nutrition; a life-stage characterised by rapid growth, body composition changes and heightened nutrient requirements. In low- and middle-income countries (LMICs), cash transfer (CT) programmes are increasingly implemented as poverty-alleviation strategies to influence diet quality and related health behaviours by relaxing household budget constraints. While evidence demonstrate…
Antibiotic overuse as a modifiable early-life risk factor for non-communicable diseases in sub-Saharan Africa
Early-life antibiotic overuse is a public health concern. In low- and middle-income countries, consumption has surged by 76% since 2000. This trend is particularly acute in sub-Saharan Africa (SSA), where antimicrobial resistance contributes to 255,000 deaths annually and infant antibiotic exposure is widespread in the first two years of life. While a substantial body of research associates antibiotic-induced microbiome disruption with metabolic …
Capacity to care
Timely breast cancer care remains challenging in South Africa, where both health-system and patient-level barriers contribute to delayed diagnosis and treatment. This study explored healthcare providers' experiences and perspectives on breast cancer care at Chris Hani Baragwanath Academic Hospital in Soweto and its two referring secondary hospitals in Johannesburg. Using a cross-sectional qualitative design informed by phenomenology, we conducted…
Young women's health behaviours in context
The Bukhali trial is being implemented with young women (18–28 years) in Soweto, South Africa. A qualitative longitudinal study was conducted to explore Bukhali trial participants' perceptions of health and their health behaviours over time and in the context of their life circumstances. This article reports an interpretation of interview data from a sub-sample of 11 of 35 participants who participated in four interviews conducted over 12 months.…
Health literacy, multimorbidity and its effect on mental health in South African adults
Objective and methods: Health literacy is a key determinant of physical and mental health outcomes, particularly in low- and middle-income settings like South Africa, where multimorbidity is increasingly common. Limited health literacy may hinder effective management of multiple chronic conditions and worsen mental health. Using repeated cross-sectional nationally representative data, this study examined the relationship between health literacy a…
Retention in the Bukhali trial in Soweto, South Africa
Introduction There is limited research on applying theory to retention in complex intervention trials. To address this gap, this study aimed to qualitatively examine retention in the Bukhali randomised controlled trial, from the perspective of trial participants and staff, through the lens of self-determination theory (SDT). The Bukhali trial is part of the Healthy Life Trajectories Initiative in Soweto, South Africa, with young women. Methods Ni…
Perceptions of preconception health messaging and responsibility
Premised on the Developmental Origins of Health and Disease theory and on the limited effectiveness of antenatal interventions, interventions in the preconception period are being conducted to potentially improve intergenerational health and non-communicable disease burdens. The Healthy Life Trajectories Initiative (HeLTI) is an international health research consortium primarily investigating the intergenerational effects of behavioural intervent…
The role of defensive functioning in positive deviance in psychological wellbeing amongst young women living in Soweto, South Africa

Drawing from the Bukhali randomized controlled trial in Soweto, which targets improved health trajectories for young women, this study focused on a group of participants who exhibited positive deviance in the trial by being employed or studying, engaging actively in the trial, …
Love, You Need to Give Your Child Love”
Background: Nurturing care of young children is aimed at promoting lifelong, intergenerational health and well‐being, as well as social and economic benefits. This study is aimed at qualitatively exploring maternal perceptions related to nurturing care, their access to information and support for caregiving, the home and community environments and practices, and how caregivers promote infants’ health and well‐being in Soweto, South Africa. Method…
We don’t care because we are not sick”
The growing burden of cardiovascular disease (CVD) in Sub-Saharan Africa (SSA) is largely driven by hypertension, with risk factors including poor diet, physical inactivity, tobacco use, psychological stress, and limited healthcare access. Early-life exposure to these risks contributes to adverse biological markers that increase hypertension susceptibility in adulthood. This study aimed to explore how young people in Soweto, Johannesburg, perceiv…
Examining maternal health literacy as a mediator of the relationship between social vulnerability and caregiving practices for improving infant development
This study examined whether specific dimensions of maternal health literacy mediated the relationship between social vulnerability and maternal caregiving confidence, specifically breastfeeding self-efficacy and maternal beliefs about play, among 168 mothers of newborns in Soweto, South Africa. Social vulnerability was measured using an adapted Social Vulnerability Index, and structural equation modelling was used to assess direct and indirect as…
Advocating for an integrated healthcare model for women of reproductive age in low- and middle-income countries
Increasingly, women are presenting in pregnancy with multi-risk and multi-morbidity profiles (combinations of pro-inflammatory diets, trauma, anxiety, depression, infections, metabolic disease, and chronic medication use); together these may independently or interactively impact fetal development. Research indicates that high levels of pro-inflammatory cytokines in the maternal womb, as well as the balance between pro- and anti-inflammatory cytok…
A qualitative analysis of community health worker perspectives on the implementation of the preconception and pregnancy phases of the Bukhali randomised controlled trial
Community health workers (CHWs) play an important role in health systems in low- and middle-income countries, including South Africa. Bukhali is a CHW-delivered intervention as part of a randomised controlled trial, to improve the health trajectories of young women in Soweto, South Africa. This study aimed to qualitatively explore factors influencing implementation of the preconception and pregnancy phases of Bukhali , from the perspective of the…
Determining the perceived acceptability of an intervention designed to improve health literacy around developmentally appropriate play during infancy, with a community advisory group of mothers, in So…
Children require opportunities to participate in unstructured, unrestricted active play as infants, to encourage positive health, socioemotional and developmental outcomes in life. Certain social and environmental factors in the home setting can limit participation in play, particularly in low resource settings. As caregivers are their infants’ first teachers, they have the important role of providing opportunities and space for children to learn…
Women’s health and well-being in five birth cohorts from low- and middle-income countries
Background: Women's health and well-being (WHW) have been receiving growing attention, but limited progress has been made on how to measure its different domains in low- and middle-income countries (LMICs). We used data from five long-term birth cohorts in Brazil, Guatemala, the Philippines and South Africa to explore different domains of adult WHW, and how these domains relate to early life exposures. Methods: Based upon an a priori conceptualis…
Adolescent mental health in sub-Saharan Africa
Addressing adolescent mental health care across sub-Saharan Africa faces numerous challenges, including underfunded public health systems, a shortage of mental health professionals, barriers to access, and pervasive stigma. Untreated adolescents often experience worsening symptoms, academic and social difficulties, physical health risks, and engage in risky behaviours. Early detection and appropriate treatment of common mental health conditions c…
Alleviating the public health burden of hypertension
Hypertension is a major global health concern, with deaths attributed to the condition expected to increase to 1.57 million by 2034, particularly affecting low-and-middle-income countries such as those within sub-Saharan Africa. Non-communicable diseases, with hypertension as a core contributor, account for 74.36% of global deaths. The burden of hypertension in sub-Saharan Africa is significant, with an estimated 10-20 million people currently af…
Feasibility Testing of a Health Literacy Intervention With Adolescents and Young Adults in South Africa
INTRODUCTION: Low health literacy levels during adolescence and young adulthood (AYA) may impact acute healthcare access and longer-term health outcomes. Previous research in South African AYA suggests that health literacy levels are typically suboptimal but few interventions exist. This study aimed to test the acceptability and feasibility of a co-created, interactive health literacy intervention (LifeLab-Soweto) with AYA in Soweto, South Africa…

Objective: To investigate food insecurity and related coping strategies, and their associations with the risk of anxiety and depression, among South African households with children. Design: Nationally representative cross-sectional study. Tools for assessing food insecurity, coping strategies, risk of anxiety and depression were assessed from the Community Childhood Hunger Identification Project, Coping Strategies Index, Generalised Anxiety Diso…
Maternal perceptions of infant's body weight and childhood obesity in South Africa
From a socio‐anthropological study focusing on maternal body weight perceptions and dietary practices towards infants living in Soweto (South Africa), we studied how lay sociocultural traits may lead to early childhood obesity. Most mothers tended to socially value and normalize fatness. This propensity led mothers, particularly older women at home, to adopt high‐calorie feeding practices towards infants, although some mothers tended to question …
Exploring the national prevalence of mental health risk, multimorbidity and the associations thereof
Objective and methods: South Africans were affected by the COVID-19 pandemic and resultant economic hardships. As a result, mental health within this region may have worsened. Therefore, using large scale nationally representative data, we repeated the cross-sectional panel study to investigate mental health risk post COVID-19 to explore mental health and multimorbidity and to examine the relationship between adverse childhood experiences (ACEs) …
Psychological legacies of intergenerational trauma under South African apartheid
BACKGROUND: South Africa's rates of psychiatric morbidity are among the highest in sub-Saharan Africa and are foregrounded by the country's long history of political violence during apartheid. Growing evidence suggests that in utero stress exposure is a potent developmental risk factor for future mental illness risk, yet the extent to which the psychiatric effects of prenatal stress impact the next generation are unknown. We evaluate the intergen…
A qualitative study to explore healthcare providers’ perspectives on barriers and enablers to early detection of breast and cervical cancers among women attending primary healthcare clinics in Johanne…
Low-and-middle income countries (LMICs) contribute approximately 70% of global cancer deaths, and the cancer incidence in these countries is rapidly increasing. Sub-Saharan African (SSA) countries, including South Africa (SA), bear some of the world’s highest cancer case fatality rates, largely attributed to late diagnosis. We explored contextual enablers and barriers for early detection of breast and cervical cancers according to facility manage…
Father Contact Following Union Dissolution for Low-Income Children in Urban South Africa
Black fathers in South Africa face enormous challenges remaining involved in their children's lives as a result of very high levels of unemployment and union instability. We use data from the Birth to Twenty (Bt20) cohort study to describe trajectories of father contact in the lives of children who have experienced a parental union dissolution and examine the influence of life stage of child at time of union dissolution and mother's entry into ne…
Children's daily travel to school in Johannesburg-Soweto, South Africa
This paper has two aims: to explore approaches to the measurement of children's daily travel to school in a context of limited geospatial data availability and to provide data regarding school choice and distance travelled to school in Soweto-Johannesburg, South Africa. The paper makes use of data from the Birth to Twenty cohort study (n = 1428) to explore three different approaches to estimating school choice and travel to school. First, straigh…
South African-ness Among Adolescents
We assessed the emergence of a South African identity among Black, Colored (mixed ancestral origin), White (predominantly English speaking), and Indian adolescents participating in a birth cohort study called "Birth to Twenty" in Johannesburg, South Africa. We examined young people's certainty of their self-categorization as South African, the centrality of their personal, racial and linguistic, and South African identities in their self-definiti…

Beliefs about the function of religion were captured by the following themes: provides support, connecti…
Effect of ethnicity and sex on the growth of the axial and appendicular skeleton of children living in a developing country
Bones in the axial and appendicular skeletons exhibit heterogeneous growth patterns between different ethnic and sex groups. However, the influence of this differential growth on the expression of bone mineral content is not yet established. The aims of the present study were to investigate: 1) whether there are ethnic and sex differences in axial and appendicular dimensions of South African children; and 2) whether regional segment length is a b…
Life History theory hypotheses on child growth
Life history theory integrates ecological, physiological, and molecular layers within an evolutionary framework to understand organisms’ strategies to optimize survival and reproduction. Two life history hypotheses and their implications for child growth, development, and health (illustrated in the South African context) are reviewed here. One hypothesis suggests that there is an energy trade‐off between linear growth and brain growth. Undernutri…
In-migration and Living Conditions of Young Adolescents in Greater Johannesburg, South Africa
While migration in South Africa has been studied on a broad canvas, there have been few accounts of children's migration and the effects on living conditions and wellbeing. This article compares the access to services, housing and household amenities, and family characteristics of children born in the Greater Johannesburg metropolis with those of in-migrant children. The article also examines other indicators of child wellbeing related to parenta…
Modelling residential mobility
Conceptualisation of child residential mobility has been influenced by developed country contexts; however, trends and models for movement are likely to differ in transitional societies. This paper uses event‐history analysis to model the residential movements of South African urban children in the Birth to Twenty cohort over their first 14 years of life. Associations with mobility of children are tested over a set of domains relating to the chil…

Perceptions and experiences of prostate cancer patients in a public tertiary hospital in urban South Africa
Prostate cancer is among the most prevalent forms of cancer worldwide and is reported to have the highest incidence, mortality, and 5-year prevalence rate of all cancers among men living in Africa. Despite this widespread burden in the African continent, little is known about the perspectives and experience of prostate cancer among African men. To further understand experiences among patients living in urban South Africa, we conducted in-depth, s…
The associations between interpersonal violence and psychological distress among rural and urban young women in South Africa
Collecting Health Research Data
Mobile phone-assisted personal interviewing (MPAPI) is becoming a more widely used technique to collect survey data. Not having a hard copy paper document to return to when cleaning data raises the question of how data error rates compare with traditional paper surveys and at what cost. One hundred health research interviewers trained to use traditional pen-and-paper (PAP) survey methodology were recruited and randomly assigned to either a PAP or…
Field Lessons From the Delivery of Questionnaires to Young Adults Using Mobile Phones
To examine the feasibility of providing young adults with mobile phones for the purpose of mobile phone–assisted self-interviewing to improve retention in a long-term birth cohort study, mobile phones with survey software were distributed to 1,000 twenty-year-olds in the Birth to Twenty birth cohort study. Eleven months later, a targeted sampling frame was used to randomly select 435 participants from the subset of 734 phones that were still func…

Cohort Profile
The late 1980s were a period of profound sociopolitical change in South Africa. It was clear that the Apartheid state was crumbling and amongst acts of civil disobedience which characterized the struggle Black Africansy began to disregard restrictive legislation that constrained where they lived and worked. Very rapid unplanned urbanization began and shanty towns mushroomed around formerly White cities and towns. It was anticipated that this rapi…

Patterns of Residential Mobility Amongst Children in Greater Johannesburg–Soweto, South Africa
Frequent residential movement challenges children to adapt to change, amongst others, houses and neighbourhoods, friends and schools, and this may have either or both negative and positive influences on their health and well-being. However, there is currently little knowledge of the patterns of child residential mobility within South Africa’s urban environment. This paper uses address data of children in the Birth to Twenty cohort to analyse the …
Adolescents in the City
Age at menarche and the evidence for a positive secular trend in urban South Africa
Menarcheal age was estimated for 287 (188 Black; 99 White) urban South African girls born in Soweto‐Johannesburg in 1990. The median menarcheal age for Blacks was 12.4 years (95% confidence interval (CI) 12.2, 12.6) and 12.5 years (95% CI 11.7, 13.3) for Whites. Data from six studies of menarcheal age, including the current study, were analyzed to examine the evidence for a secular trend between 1956 and 2004 in urban South African girls. There w…
Is puberty starting earlier in urban South Africa
Age at the initation of pubertal development was estimated for 401 Black (212 boys) and 206 White (100 boys) urban South African adolescents born in Soweto‐Johannesburg in 1990. Average age at the initation of puberty, assessed by age at the transition from Tanner Stage 1 to Tanner Stage 2 for breast/genitalia or pubic hair development ranged between 9.8 and 10.5 years. There were no statistically significant differences in age at initiation betw…
Approaches for assessing the role of household socioeconomic status on child anthropometric measures in urban South Africa
The objectives of this article were to compare the variance explained in anthropometric outcomes when using individual measures of socioeconomic status (SES) versus different approaches to create SES indices within the urban African context, and to examine the influence of SES measured during infancy on child anthropometric outcomes at 7/8 years. Data from the 1990 Birth‐to‐Twenty cohort study set in Johannesburg‐Soweto, South Africa, were used (…
Studying a Population Undergoing Nutrition Transition
The South African Medical Research Council food frequency questionnaire (FFQ) and protocol was used to determine food intake in 83 adolescents from the Birth To Twenty study. The FFQ was piloted on a small group (n=8). Specific problems which resulted in overestimation of energy intake were identified. The protocol was modified and administered to the remainder of the adolescents and their caregivers. Reasonable energy intakes were obtained, and …
Secular trends in skeletal maturity in South Africa
Significant secular increases in the skeletal maturity of urban black South African children occurred between 1962 and 2001. Non-significant increases were seen in white children. The significant secular increases were concordant with increases in stature and adiposity during this period. The increase in skeletal maturity may reflect the removal of growth constraint, particularly in black children
ÂYou opened our eyesâ
Caregivers of young children identified as HIV positive, residing in Agincourt, rural South Africa were advised of their child's status. How was this knowledge received, and how did it influence care-giving and support? Interviews were conducted in May to June 2008 with caregivers of HIV positive children aged 1-5 years, 1 year following the child's HIV test and disclosure of status. Drawing on data from 31 semi-structured questionnaires and 21 i…
Growth patterns in early childhood and final attained stature
Growth failure is cumulative, and short stature is associated with multiple indices of reduced human capital. Few studies have been able to address in a single analysis both consideration of the timing of growth failure and comparison across populations. We analyzed data from birth cohorts in Brazil, Guatemala, India, the Philippines, and South Africa ( n = 4,659). We used data on length at birth (available for three of the five cohorts), 12 mo, …
The prevalence of stunting, overweight and obesity, and metabolic disease risk in rural South African children
The study highlights that in transitional societies, early stunting and adolescent obesity may co-exist in the same socio-geographic population. It is likely that this profile relates to changes in nutrition and diet, but variation in factors such as infectious disease burden and physical activity patterns, as well as social influences, need to be investigated. As obesity and adult short stature are risk factors for metabolic syndrome and Type 2 …
