Propensity for adverse pregnancy outcomes in African-American women may be explained by low energy expenditure in early pregnancy.

ABSTRACT:

Background

African-American (AA) women have poorer pregnancy outcomes, and studies in nonpregnant women suggest a different etiology of weight gain in AA compared with white women. We hypothesized that physiologic factors such as low energy expenditure and physical activity would be present in AA compared with white women in pregnancy.

Objective

We aimed to identify physiologic risk factors for disordered energy balance in AA and white women early in pregnancy.

Design

This was a cross-sectional study in 66 pregnant women with obesity, between 14 and 16 wk of gestation. Energy intake was calculated using the intake-balance method. Energy expenditure was measured in free-living conditions [total daily energy expenditure (TDEE)] over 7 d with the use of doubly labelled w
