^aAs reported for the full cohort of 45 women in Lambert-Messerlian et al. 2016 (17). Subject-level data not available.

^bEstimated from (17).

^cAdolescents were more likely to be overweight/obese than adults; P < 0.001 for comparison of body mass index percentiles; P = 0.002 for body mass index categories.
