MeasureTime frame
1. Metabolic syndrome measured using the definition of the International Diabetes Federation (IDF) at one timepoint 2. Body fat measured using the deuterium dilution technique at one timepoint 3. Anthropometric measurements, including weight, height, waist circumference, mid-upper arm circumference and calf circumference, measured using standardized protocols to calculate BMI and BMI z-scores at one timepoint

Secondary

MeasureTime frame
Total body water, fat mass and fat-free mass measured using bioimpedance vector analysis (BIVA) at one timepoint

Countries
