Leisure time physical activity before and during mid-pregnancy and offspring adiposity in mid-childhood.

ABSTRACT:

Background

Effects of maternal leisure time physical activity (LTPA) on paediatric obesity are unknown. The objective of this study was to examine associations of maternal LTPA with offspring overall and central adiposity in mid-childhood.

Methods

We analysed data from 802 mother-child dyads from Project Viva, a prospective pre-birth cohort study. Women reported average weekly LTPA before and during mid-pregnancy. At age 7-10 years, we measured fat, truncal fat and lean mass with dual-energy X-ray absorptiometry. Using multivariable linear regression, we examined associations of maternal LTPA with offspring adiposity, adjusting for child age and sex, maternal race/ethnicity, education, age, pre-pregnancy body mass index, marital status and smoking status.
