Abbreviations: BMI, body mass index; ENMO, The Euclidean norm minus 1 g with negative numbers rounded to zero; n, number; PA, physical activity. Body mass index was calculated as weight in kilograms divided by height in meters squared. Categories were defined as normal weight: 18.5 < 25 kg/m2, overweight: 25 < 30 kg/m2 and obese: ≥ 30 kg/m2.
Results are obtained from t-tests for determinants with two categories and analysis of variance (ANOVA) for determinants with 3 or more categories. Data are mean (SD).
Total N varies due to variation in the amount of missing data for different covariates.
