FIGURE 1.

Comparison of energy intake and EE between AA and white women in early pregnancy. Data are presented as means ± SEMs. (A) Energy intake was calculated by the intake-balance method, combination between doubly labeled water and changes in fat-free and fat mass (AA: n = 26; white: n = 31); and macronutrient composition using food photography (AA: n = 25; white: n = 26). (B) EE was measured over 7 d using doubly labeled water (TDEE) and once overnight (0200–0500) in whole-room calorimetry (SleepEE). *Significant difference in total energy intake between AA and white women (P < 0.05), whereas macronutrient composition was comparable between the groups. AA, African American; EE, energy expenditure; SleepEE, sleeping energy expenditure; TDEE, total daily energy expenditure.
