May R, et al. Growth pattern of overweight preschool children in the Siouxland WIC Program. Am J Hum Biol. Nov 2002;14(6):769-776.
This study analyzed the relationship between height and weight and several variables for preschool children enrolled in the Siouxland WIC Program. The children had a large average increase in weight between birth and 8 months and between 12 months and 30 months. Overweight children were different from their normal-weight peers in birthweight, monthly household income, number of people living in the household, and mother’s education level. Variables influencing changes in weight included birthweight, sex of child, breastfeeding status, and household size.
