Data are Mean ± SE. Significant at . BMI: body mass index; FSIGT: frequently-sampled intravenous glucose tolerance test; SI: insulin sensitivity; AIRG: acute insulin response to glucose; DI: disposition index. values were calculated using Chi-square (i.e., sex, Tanner stage, and household social position); Student's -tests (i.e., age, anthropometry, dietary intake, physical activity and sedentary time) and analysis of covariance (i.e., glucose and insulin indices). Covariates included: sex, Tanner stage, fat/fat-free mass. While unadjusted means are reported here for all variables, analyses were based on log scores for age, fasting insulin, insulin sensitivity, acute insulin response, total dietary intake, assimilation, separation, integration, and marginalization.
