Resting metabolic rate (RMR) and body composition were measured in 44 initially non-overweight girls at 3 time points relative to menarche: premenarche (Tanner stage 1 or 2), menarche (± 6 mo), and 4 y after menarche. Mean absolute RMR was 1167, 1418, and 1347 kcal/d, respectively. Absolute RMR was statistically significantly higher at menarche than 4 y after menarche despite statistically significantly less fat-free mass (FFM) and fat mass (FM), suggesting an elevation in RMR around the time of menarche. The pattern of change in RMR adjusted for FFM, lnFM, age, race, parental overweight, and two interactions (visit by parental overweight, parental overweight by FFM) was also considered. Adjusted RMR did not differ statistically between the visits for girls with 2 normal-weight parents. For girls with at least 1 overweight parent, adjusted RMR was statistically significantly lower 4 y after menarche than at premenarche or menarche. Thus, parental overweight may influence changes that occur in RMR during adolescence in girls.
