Inequality between and within populations has origins in adverse early experiences. Developmental neuroscience shows how early biological and psychosocial experiences affect brain development. We previously identified inadequate cognitive stimulation, stunting, iodine deficiency, and iron-deficiency...

BACKGROUND: Stay-at-home orders (lockdowns) have been deployed globally to control COVID-19 transmission, and might impair economic conditions and mental health, and exacerbate risk of food insecurity and intimate partner violence. The effect of lockdowns in low-income and middle-income countries mu...

BACKGROUND: Exposure to arsenic through drinking water has been associated with impaired cognitive function in school-aged children in a few cross-sectional studies; however, there is little information on critical windows of exposure. METHODS: We conducted a population-based longitudinal study in r...

Poor stimulation in the home is one of the main factors affecting the development of children living in poverty. The family care indicators (FCIs) were developed to measure home stimulation in large populations and were derived from the Home Observations for Measurement of the Environment (HOME). Th...

BACKGROUND Iron and zinc deficiency are prevalent during infancy in low-income countries. OBJECTIVES The objectives were to examine whether a weekly supplement of iron, zinc, iron+zinc, or a micronutrient mix (MM) of 16 vitamins and minerals would alter infant development and behavior. DESIGN The pa...

Undernutrition in early childhood is associated with poor mental development and affects 45% of children in Bangladesh. Although limited evidence shows that psychosocial stimulation can reduce the deficits, no such interventions have been reported from Bangladesh. The Bangladesh Integrated Nutrition...

BACKGROUND: Cadmium is a commonly occurring toxic food contaminant, but health consequences of early-life exposure are poorly understood. OBJECTIVES: We evaluated the associations between cadmium exposure and neurobehavioral development in preschool children. METHODS: In our population-based mother-...

BACKGROUND: Cadmium (Cd) is an embryotoxic and teratogenic metal in a variety of animal species, but data from humans are limited. OBJECTIVES: The aim of the present study was to assess the effects of maternal Cd exposure in pregnancy on size at birth. METHODS: This prospective cohort study was nest...

Background Few data exist for the effects of multiple micronutrient (MM) or food supplementation to undernourished pregnant women on their offsprings' development. Objective We aimed to compare the effects on infant development of early (8-10 wk gestation) or usual ( approximately 17 wk gestation) s...

In this prospective cohort study, based on 1,505 mother-infant pairs in rural Bangladesh, we evaluated the associations between early-life exposure to arsenic, cadmium, and lead, assessed via concentrations in maternal and child urine, and children's weights and heights up to age 5 years, during the...

OBJECTIVE: Nipah virus (NiV) is an emerging zoonosis. Central nervous system disease frequently results in high case-fatality. Long-term neurological assessments of survivors are limited. We assessed long-term neurologic and functional outcomes of 22 patients surviving NiV illness in Bangladesh. MET...

OBJECTIVE: To examine how maternal depressive symptoms are related to infant development among low-income infants in rural Bangladesh and to examine how the relationship is affected by maternal perceptions of infant irritability and observations of caregiving practices. METHODS: Development was meas...

OBJECTIVE: We aimed to determine the timing and size of the cognitive deficit associated with poverty in the first 5 years of life and to examine the role of parental characteristics, pre- and postnatal growth, and stimulation in the home in Bangladeshi children. We hypothesized that the effect of p...

Background/objectives Young children with severe malnutrition usually have poor mental development. Psychosocial stimulation may reduce their cognitive deficit, but it is not usually provided. The aim of the study was to incorporate stimulation into the routine treatment of severely malnourished chi...

Background Zinc deficiency is widely prevalent in developing countries. Zinc supplements given to Bangladeshi pregnant women have been shown to reduce infants' infectious disease morbidity. We assessed these infants at age 13 months to establish the effect of antenatal zinc supplementation on infant...
