T2 Men (min 7.61 / 9.34max); Women (min 7.16 / 8.73max). T3, Men (min 9.35 / 17.2 max), Women (min 8.74/ 15.15max). Tertiles were calculated using the total sample of 2189, and the sample size shown corresponds to the distribution of these 2189 individuals within tertiles; the sample size within tertiles varied for outcome variables with different total sample size. Sample sizes in tertiles of body composition variables determined by DXA were: T1, n = 225; T2, n = 219; T3, n = 218. bData shown of time in bed, physical activity and inactive time has been recorded by accelerometer. High waist circumference was defined has a circumference ≥ 120 cm in men and ≥ 88 cm in women. High glucose was defined as ≥110 mg/dl of glucose in blood or antidiabetic treatment with metformin or insulin. High levels of triglycerides was defined as ≥150 mg/dl of blood. Low levels of HDL cholesterol was defined as ≤40 mg/dl in men and ≤ 50 mg/dl in women. Obesity was defined with a BMI ≥30 kg/m2. Hypertension was defined with a SBP ≥90 mmHg and a SBP ≥140 mmHg. It was considered diabetes if the participant has a previous diagnosis of diabetes, with a HbA1c (%) ≥6.5, or with the use of medication for diabetes treatment as insulin and metformin
