Longitudinal patterns of child development and socioeconomic status are described for a cohort of children in Madagascar surveyed when 3-6 and 7–10 years old. Substantial wealth gradients were found across multiple domains: receptive vocabulary, cognition, sustained attention, and working...

Worldwide, 250 million children under five (43%) are not meeting their developmental potential because they lack adequate nutrition and cognitive stimulation in early childhood. Several parent support programs have shown significant benefits for children's development, but the programs are often...

Female Sex Workers are a core population in the HIV epidemic, and interventions such as conditional cash transfers (CCTs), effective in other health domains, are a promising new approach to reduce the spread of HIV. Here we investigate how a population of Tanzanian female sex workers, though...

Correlational studies have shown associations between social class and salivary cortisol suggestive of a causal link between childhood poverty and activity of the stress-sensitive hypothalamic-pituitary-adrenocortical (HPA) system. Using a quasi-experimental design, we evaluated the associations...

The study reported here explored the associations of body mass index (BMI), socio-economic status (SES), and beverage consumption in a very low-income population. A house-to-house survey was conducted in 2003 of 12,873 Mexican adults. The sample was designed to be representative of the poorest...

Poverty, both absolute and relative, is associated with poorer health. This is of particular concern in middle- and low-income countries facing a significant and growing burden of disease. There has been limited research specifically on whether interventions that increase income may foster...

There is increasing evidence that cash transfer (CT) programs decrease intimate partner violence (IPV). However, little is known about how CTs achieve this impact. We conducted a mixed-method review of studies in low- and middle-income countries (LMICs). Fourteen quantitative and eight...

Violence against women is a major health and human rights problem yet there is little rigorous evidence as to how to reduce it. We take advantage of the randomized roll-out of Ecuador's cash transfer program to mothers to investigate how an exogenous increase in a woman's income affects domestic...

The debate over whether to provide food-assistance and the form that this assistance should take has a long history in economics. Despite the ongoing debate, little rigorous evidence exists that compares food-assistance in the form of cash versus in-kind. This paper uses a randomized evaluation...
