Fetal growth does not modify the relationship of infant weight gain with childhood adiposity and blood pressure in the Southampton women's survey.

ABSTRACT: Background: Rapid infant weight gain is a risk factor for childhood obesity. This relationship may depend on whether infant weight gain is preceded by in-utero growth restriction.Aim: Examine whether fetal growth modifies the relationship between infant weight gain and childhood adiposity and blood pressure.Subjects and methods: 786 children in the Southampton Women's Survey. We related infant weight gain (weight at 2 years-birth weight) to body mass index (BMI), %body fat, trunk fat (kg), systolic (SBP) and diastolic blood pressure (DBP) at age 6-7 years. Mean estimated fetal weight (EFW) between 19-34 weeks and change in EFW (19-34 weeks) were added to models as effect modifiers.Results: Infant weight gain was positively associated with all childhood outcomes.
