  1. Information was derived from self-reports during a personal interview, anthropometric measures were taken by trained personnel
  2. 95% CI, 95% confidence interval; BMI, body mass index; n. a., not available; OR, odds ratio; PA, physical activity; vs., versus; WC, waist circumference; WHO, World Health Organization.
  3. *Results were derived from a multivariable logistic regression analysis with factors potentially related to physical activity included as independent and fulfilment of the World Health Organization (WHO) physical activity recommendation included as dependent variable. β-coefficients can be interpreted as change in the likelihood (odds ratio, OR) of meeting the WHO recommendation, referring to a 1-unit increase for continuous variables or to the respective reference category for categorical variables. Model includes sex, age, body mass index (BMI), waist circumference (residually adjusted for BMI), smoking status, alcohol consumption, university entrance qualification, employment status, net household income, marital status, diabetes, dyslipidaemia, and study centre.
  4. a‘Meeting the WHO PA recommendation’ (‘yes’) was defined as accumulating ≥150 min/week or ≥75 min/week of vigorous activity/week (here: VV activity) (mean weekly estimates: mean min/d per participant multiplied by 7), spent in activity bouts ≥10 minutes, or an equivalent combination of these1. For the latter, metabolic equivalents of tasks (METs)/week were calculated, when multiplying mean weekly estimates in moderate and VV activity by 4 and 8 METs, respectively, as described before29. Achieving with the sum of both ≥450 METs/week, this was classified as ‘meeting WHO PA recommendation’. Not meeting any of the aforementioned criteria was classified as ‘not meeting WHO recommendation’.
  5. bResidually adjusted for BMI.
  6. Bold: statistically significant when accounting for multiple testing (p-value <0.01).
