Results are expressed as median and (interquartile range, IQR) for values over detection level, and as % (all subjects). BMI, body mass index; CVD, cardiovascular disease; LOD, limits of detection; PA, physical activity. Statistical analysis by Kruskall-Wallis nonparametric test (for medians) and by chi-square (for percentages):

^NS, not significant;

**, p<0.01;

***, p<0.001.
