Journal article ; Background: Exposure to arsenic via drinking water has been associated with adverse pregnancy outcomes and infant morbidity and mortality. Little is known, however, about effects of arsenic on child growth. Objective: To assess potential effects of early-life arsenic exposure on weight and length of children from birth to 2 years of age. Methods: We followed 2372 infants born in a population-based intervention trial in rural Bangladesh. Exposure was assessed by arsenic concentrations in urine (U-As) of mothers (gestational weeks 8 and 30) and children (18 months old). Child anthropometry was measured monthly in the first year and quarterly in the second. Linear regression models were used to examine associations of U-As (by quintiles) with child weight and length, adjusted for age, maternal BMI, SES, and sex (or stratified by sex). ; IFPRI-3; ISI; PHND; PR
