This study, using longitudinal data from the South African Birth to Twenty Plus study, assessed associations between early childcare quality in the home between six months and two years, household SES and cognitive development at age 5. Childcare quality was assessed using measures of maternal responsiveness and cognitive stimulation. Cognitive development at age 5 was assessed using the Revised Denver Pre-screening Developmental Questionnaire (R-DPDQ). Bivariate analysis and multiple linear regressions were conducted. The analytical sample comprised 856 mother–child pairs. Quality of care in the home differed significantly according to SES status, with more children in the low SES group receiving low quality of care. There was no association between childcare quality and cognitive development. There were differences in the cognitive development scores of children in different socio-economic groups; high levels of cognitive stimulation in the home were associated with increased R-DPDQ scores for children in the low SES group.
The South African National Integrated Early Childhood Development Policy was approved by the South African Cabinet in 2015. Given capacity and financial constraints, all services outlined cannot be implemented in a single step. Priorities must be set. We examine the budget implications (total cost and cost per child) and benefits of the four largest components of the Policy: interventions to improve pregnancy outcomes; home visits for at-risk mothers of children under 2 years of age; community-based playgroups for mothers and children, and center-based early childhood development services. Further, we identify which services are based on the strongest evidence, the value-based trade-offs that characterise the prioritising decisions, and which logistical factors favour alternative orderings of services. The interventions to improve pregnancy outcomes are low cost, based on sound evidence and would make use of the established healthcare infrastructure. Home visits for at-risk mothers are associated with improved development for targeted children and consequential benefits for caregivers and broader society. Playgroups are a promising low-cost intervention, but further evidence is required to determine their effectiveness. Centre-based services are expensive and generate smaller developmental returns, but provide childcare. The results highlight the value judgements required to determine the appropriate sequencing of interventions.

Importance: Few studies from low-and-middle income countries have investigated long-term associations between maternal postnatal depression and offspring internalizing (ie, depressive and anxiety) symptoms, and none have investigated interactions in this association. Objective: To investigate the association between maternal postnatal depression and offspring internalizing symptoms from adolescence to adulthood and the interaction with exposure to socioeconomic adversity and with the child's sex. Design, Setting, and Participants: This secondary analysis used data from Birth to Twenty Plus (BT20+), a prospective birth cohort study of children born in Soweto, South Africa, and followed up until age 28 years. Data were collected from 1990 to 2018, and data were analyzed for this study from February 16 through December 15, 2020. Exposures: Maternal postnatal depression self-reported by mothers 6 months after childbirth. Main Outcomes and Measures: The main outcome was offspring internalizing symptoms, assessed at offspring ages 14 years, 22 years, and 28 years and modeled longitudinally. Participants with the highest probability of experiencing high internalizing symptoms (ie, those in the top 20% of the distribution) from age 14 to 28 years were categorized as belonging to the high internalizing symptoms trajectory (vs the low trajectory). Socioeconomic adversity was measured with an index (continuous variable) including low maternal education, household crowding, low assets, and low maternal age. This variable was further stratified into more than 1 SD above the mean index, more than 1 SD below the mean index, and from 1 SD below to 1 SD above the mean index to conduct subgroup analyses. Associations were investigated using multivariable regression models. Results: Among 1087 participants born in Soweto, South Africa (543 [50.0%] male participants; 544 [50.0%] female participants), 118 individuals (10.8%) showed a high trajectory of internalizing symptoms from age 14 to 28 years vs 969 individuals (89.1%) with a low trajectory. Children exposed to maternal postnatal depression had statistically significantly increased odds of following the high trajectory (adjusted odds ratio [aOR] per 1-SD increase in maternal postnatal depression, 1.20; 95% CI, 1.02-1.41). This increase in odds differed by exposure to socioeconomic adversity and by child sex: for male participants, the increase in odds was greater in a context of higher vs lower socioeconomic adversity (eg, for >1 SD above the mean: aOR, 3.28; 95% CI, 1.06-10.14 vs for >1 SD below the mean: aOR, 0.98; 95% CI, 0.64-1.50; P for interaction = .12), while for female participants, the increase in odds was greater in a context of lower vs higher socioeconomic adversity (eg, for >1 SD below the mean: aOR, 1.82; 95 % CI, 1.12-2.98 vs for >1 SD above the mean: aOR, 0.59; 95 % CI, 0.30-1.17; P for interaction = .002) (P for 3-way interaction = .003). Conclusions and Relevance: This study found that postnatal depression was associated with higher odds of persistently increased internalizing symptoms among offspring from adolescence to adulthood in a middle-income country, with variation by socioeconomic adversity and sex. These findings suggest that better understanding of these associations is needed to implement targeted interventions and maximize the impact of public health initiatives aimed at breaking the intergenerational transmission of mental health problems.

BACKGROUND: The 2016 World Health Organization Antenatal Guidelines and the 2015 South African Maternal and Child Health Guidelines recommend one early antenatal ultrasound scan to establish gestational age and to detect multiple pregnancies and fetal abnormalities. Prior research indicates that ultrasound scan can also increase parental-fetal attachment. We aim to establish whether, compared to routine care, messages to promote parental attachment and healthy child development, conducted during one or two pregnancy ultrasound scans, improve early child development and growth, exclusive breastfeeding, parental-child interactions and prenatal and postnatal clinic attendance. METHODS: The effect of messages to sensitise mothers and fathers to fetal development will be tested in a three-armed randomised trial with 100 mothers and their partners from Soweto, Johannesburg in each arm. The primary outcome is child development at 6 months postnatally. Secondary outcomes include infant feeding, parental attachment and interaction, parental mental health and infant growth, assessed at 6 weeks and 6 months. Parents in Arm 1 receive a fetal ultrasound scan < 25 weeks during routine antenatal care at tertiary hospitals, and a second standard ultrasound scan at the research site within 2 weeks. Arm 2 participants receive the routine antenatal ultrasound scan and an additional ultrasound scan < 25 weeks at the research site, together with messages to promote parental attachment and healthy child development. Arm 3 participants receive the routine ultrasound scan and two additional ultrasound scans at the research site, < 25 weeks and < 36 weeks, together with messages to promote parental attachment and healthy child development. DISCUSSION: Evidence from high-income countries suggests that first-time prospective mothers and fathers enjoy seeing their fetus during ultrasound scan and that it is an emotional experience. A number of studies have found that ultrasound scan increases maternal attachment during pregnancy, a predictor of positive parent-infant interactions which, in turn, promotes healthy infant development. It is generally agreed that studies are needed which follow up parental-child behaviour and healthy child development postnatally, include fathers and examine the construct in a wider diversity of settings, especially in low and middle-income countries. Testing the added benefits of pregnancy ultrasound scan for child development is a gap that the proposed trial in South Africa seeks to address.

BACKGROUND: Understanding how gender norms affect health is an important entry point into designing programs and policies to change norms and improve gender equality and health. However, it is rare for global health datasets to include questions on gender norms, especially questions that go beyond measuring gender-related attitudes, thus limiting gender analysis. METHODS: We developed five case studies using health survey data from six countries to demonstrate approaches to defining and operationalising proxy measures and analytic approaches to investigating how gender norms can affect health. Key findings, strengths and limitations of our norms proxies and methodological choices are summarised. FINDINGS: Case studies revealed links between gender norms and multiple adolescent health outcomes. Proxys for norms were derived from data on attitudes, beliefs, and behaviours, as well as differences between attitudes and behaviours. Data were cross-sectional, longitudinal, census- and social network-based. Analytic methods were diverse. We found that gender norms affect: 1) Intimate partner violence in Nigeria; 2) Unhealthy weight control behaviours in Brazil and South Africa; 3) HIV status in Zambia; 4) Health and social mobility in the US; and 5) Childbirth in Honduras. INTERPRETATION: Researchers can use existing global health survey data to examine pathways through which gender norms affect health by generating proxies for gender norms. While direct measures of gender norms can greatly improve the understanding of how gender affects health, proxy measures for norms can be designed for the specific health-related outcome and normative context, for instance by either aggregating behaviours or attitudes or quantifying the difference (dissonance) between them. These norm proxies enable evaluations of the influence of gender norms on health and insights into possible reference groups and sanctions for non-compliers, thus informing programmes and policies to shape norms and improve health.

Background: Early growth faltering accounts for one-third of child deaths, and adversely impacts the health and human capital of surviving children. Social as well as biological factors contribute to growth faltering, but their relative strength and interrelations in different contexts have not been fully described. Objective: The aim of this study was to use structural equation modelling to explore social and biological multidetermination of child height at age 2 y in longitudinal data from 4 birth cohort studies in low- and middle-income countries. Methods: We analyzed data from 13,824 participants in birth cohort studies in Brazil, India, the Philippines, and South Africa. We used exploratory structural equation models, with height-for-age at 24 mo as the outcome to derive factors, and path analysis to estimate relations among a wide set of social and biological variables common to the 4 sites. Results: The prevalence of stunting at 24 mo ranged from 14.0% in Brazil to 67.7% in the Philippines. Maternal height and birthweight were strongly predictive of height-for-age at 24 mo in all 4 sites (all P values <0.001). Three social-environmental factors, which we characterized as "child circumstances," "family socioeconomic status," and "community facilities," were identified in all sites. Each social-environmental factor was also strongly predictive of height-for-age at 24 mo (all P values <0.001), with some relations partly mediated through birthweight. The biological pathways accounted for 59% of the total explained variance and the social-environmental pathways accounted for 41%. The resulting path coefficients were broadly similar across the 4 sites. Conclusions: Early child growth faltering is determined by both biological and social factors. Maternal height, itself a marker of intergenerational deprivation, strongly influences child height at 2 y, including indirect effects through birthweight and social factors. However, concurrent social factors, many of which are modifiable, directly and indirectly contribute to child growth. This study highlights opportunities for interventions that address both biological and social determinants over the long and short term.

Abstract Motivation Investing in girls' schooling in low‐ and middle‐income countries (LMICs) is seen as central to improving gender equity. It is argued that interventions to promote girls' enrolment are appropriate as girls face gendered barriers to school enrolment and completion and investing in girls' schooling has high economic and human development returns. But is this fair to boys and enough for girls? Purpose We ask how appropriate it is to direct development assistance towards improving girls' school enrolment, compared to prioritizing schooling for both girls and boys, and addressing barriers to gender equality throughout the life course. Methods and approach We frame the enquiry through a human development framework with three distinct but interdependent domains: protection of human development potential; realization of human development potential; and use of human development potential. Using publicly available data, we identify indicators that are likely to be correlated with the degree to which human development potential is protected, realized, and utilized in LMICs. We compare male and female outcomes on each of these indicators to assess gender parity at different life stages. Findings In most regions, girls are ahead of boys in both school enrolment and completion. Girls have better outcomes than boys in several other indicators in early life and childhood. In adolescence and adulthood, girls and women fall behind boys and men. This is especially apparent in workforce participation, in unemployment, in pay, and in share of unpaid care work and political participation, where women have less favourable outcomes than men. The bias against women is most marked in South Asia and sub‐Saharan Africa. Policy implications A focus on girls' schooling should be tempered by ensuring quality pre‐primary, primary, and secondary schooling for both boys and girls. At the same time, we must address causes of gender inequality, including labour market discrimination and social norms that justify the exclusion and exploitation of women and girls.

Abstract There is incontrovertible evidence that early learning opportunities shape long-term development and health. Nevertheless, early childhood care and education (ECCE) is not expressly mentioned as part of the right to education in the Convention on the Rights of the Child, the International Covenant on Economic, Social and Cultural Rights, and the Convention on the Rights of Persons with Disabilities. This paper argues that the right to education can nevertheless be regarded as including ECCE. We examine the treaties, General Comments, and 264 Concluding Observations by relevant UN monitoring bodies, covering 152 countries from 2015 to 2020, to determine whether the right to ECCE is regarded as part of States’ obligations and the content of the duty. These demonstrate consistently that States must provide affordable, accessible, quality, inclusive ECCE, with adequate resources. We argue that monitoring committees should draw these obligations together in one General Comment, thereby improving States’ accountability and guiding the delivery of ECCE.

Interventions to reduce undernutrition and improve child growth have incorporated improved water, sanitation, and hygiene (WASH) as part of disease transmission prevention strategies. Knowledge gaps still exist, namely, when and which WASH factors are determinants for growth faltering, and when WASH interventions are most effective at improving growth. This study drew cross-sectional data from a longitudinal cohort study and used hierarchical regression analyses to assess associations between WASH factors: water index, sanitation, hygiene index, and growth: height-for-age (HAZ), weight-for-age (WAZ), weight-for-height (WHZ) at 1, 6, and 12 months postpartum among infants a priori born healthy in Soweto, Johannesburg. Household access to sanitation facilities that were not safely managed was associated with a decrease in HAZ scores at 1 month (β = -2.24) and 6 months (β = -0.96); a decrease in WAZ at 1 month (β = -1.21), 6 months (β = -1.57), and 12 months (β = -1.92); and finally, with WHZ scores at 12 months (β = -1.94). Counterintuitively, poorer scores on the hygiene index were associated with an increase at 1 month for both HAZ (β = 0.53) and WAZ (β = 0.44). Provision of safely managed sanitation at household and community levels may be required before improvements in growth-related outcomes are obtained.

BACKGROUND: The COVID-19 pandemic and containment measures have severely affected families around the world. It is frequently assumed that digital technologies can supplement and perhaps even replace services for families. This is challenging in conditions of high device and data costs as well as poor internet provision and access, raising concerns about widening inequalities in availability of support and consequent effects on child and family outcomes. Very few studies have examined these issues, including in low- and middle-income countries. OBJECTIVE: The study objectives were two-fold. The first objective was to gather data on the impact of the COVID-19 pandemic on families of young children using an online survey. The second objective was to assess the feasibility of using a data-free online platform to conduct regular surveys and, potentially, to provide support for parents and families of young children in South Africa. METHODS: We used a data-free mobile messenger platform to conduct a short digital survey of the impact of the COVID-19 pandemic on caring for young children in South Africa. We report on the methodological processes and preliminary findings of the online survey. RESULTS: More than 44,000 individuals accessed the survey link and 16,217 consented to the short survey within 96 hours of its launch. Respondents were predominantly from lower classes and lower-middle classes, representing the majority of the population, with urban residential locations roughly proportionate to national patterns and some underrepresentation of rural households. Mothers comprised 70.2% (11,178/15,912) of respondents and fathers comprised 29.8% (4734/15,912), representing 18,672 children 5 years of age and younger. Response rates per survey item ranged from 74.8% (11,907/15,912) at the start of the survey to 50.3% (8007/15,912) at completion. A total of 82.0% (12,729/15,912) of parents experienced at least one challenge during the pandemic, and 32.4% (2737/8441) did not receive help when needed from listed sources. Aggregate and individual findings in the form of bar graphs were made available to participants to view and download once they had completed the survey. Participants were also able to download contact details for support and referral services at no data cost. CONCLUSIONS: Data-free survey methodology breaks new ground and demonstrates potential not previously considered. Reach is greater than achieved through phone surveys and some social media platforms, men are not usually included in parent surveys, costs are lower than phone surveys, and the technology allows for immediate feedback to respondents. These factors suggest that zero-rated, or no-cost, services could provide a feasible, sustainable, and equitable basis for ongoing interactions with families of young children.
