在相对于初潮的三个时间点：初潮前（坦纳阶段1或2）、初潮（+/-6个月）和初潮后4年，对44名最初不超重的女孩测量静息代谢率（RMR）和身体成分。平均绝对RMR分别为1，167、1，418和1，347 kcal/天。绝对RMR在初潮时比初潮后4年有统计学显著性升高，尽管无脂肪质量（FFM）和脂肪质量（FM）有统计学显著性降低，表明初潮时RMR升高。还考虑了RMR的变化模式，经FFM、对数转换FM、年龄、种族、父母超重和两种相互作用（父母超重的访视，FFM的父母超重）调整。对于父母体重正常的女孩，校正后的RMR在两次访视之间没有统计学差异。对于父母中至少有一方超重的女孩，初潮后4年的校正RMR在统计学上显著低于初潮前或初潮时。因此，父母超重可能会影响的变化，发生在RMR青春期的女孩。
Resting metabolic rate (RMR) and body composition were measured in 44 initially nonoverweight girls at three time points relative to menarche: premenarche (Tanner stage 1 or 2), menarche (+/-6 mo), and 4 yr after menarche. Mean absolute RMR was 1,167, 1,418, and 1,347 kcal/day, respectively. Absolute RMR was statistically significantly higher at menarche than at 4 yr 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, log transformed FM, 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 two normal-weight parents. For girls with at least one overweight parent, adjusted RMR was statistically significantly lower 4 yr after menarche than at premenarche or menarche. Thus parental overweight may influence changes that occur in RMR during adolescence in girls.
