*Bolded values indicate significance at P < 0.05. † n = 1340, F statistic = 1.62 (P = 0.17) for the overweight status multivariate Poisson regression model.
§ Skinfold thicknesses = (Subscapular + Triceps skinfolds). n = 1339, r2 = 0.037 (P = 0.009) for the skinfolds multivariate linear regression model.
