Table 3 Differences in measures of fat mass from 18 to 22 years of age (measurements at 22 – measurements at 18 years) by sex, according to socioeconomic and demographic characteristics, maternal information and dietary intake at 18 years

From: Evolution of total body and regional adiposity from late adolescence to early adulthood in a birth cohort study
