Objective Weight gain that exceeds the expected growth trajectory in early life has been shown to determine child Overweight and obesity (OW+O) but most studies have been conducted in urban children from developed countries. Information is also lacking from breastfed populations. Methods We studied a panel of 1496 children from the Young Lives project in Peru of whom 98% had been breastfed. Generalized estimated equations were used to examine the relation between BMI at aged 8 y and weight for age increase of >;0.67 Z score from birth to aged 6–18m (infant) and between this age and 4–5 y (child). We adjusted for sex, maternal BMI, wealth index, maternal education, and height for age, physical exercise, “fast food” and soda drink consumption and hours of sleep at aged 8 y. Rural and urban children were examined separately. Results Rapid weight gain in infancy and early childhood both significantly increased the risk of later OW+O in rural (infant OR 2.21, child 2.06) and urban (infant OR 2.28, child OR 3.10) children. The relationship remained significant in adjusted models. Conclusion Growth in both infancy and early childhood contributes to childhood OW+O even in breastfed populations. It is necessary to understand the mechanisms for this in order to identify modifiable practices.
