  1. Adjusted: sedentary behavior; nutritional score; use of cigarettes, alcohol and drugs; other physical activity domains and variables in the table.
  2. Crude PR might be obtained by dividing the prevalence between strata.
  3. *Involved at least 2 days per week.
  4. **Involved at least 1 day per week.
  5. ***At least 300 minutes of physical activity per week.
  6. Bold data reflect statistical significance (p < .05).
