a Adjusted for age and sex
Category 0 was for the lowest and 5 for the highest levels of self-reported PA. Categories 4 and 5 were combined with category 3 due to low response frequencies in categories 4 and 5. Additional models with recategorized categories were used due to the low response frequencies in the lowest categories. One participant was missing data on self-reported physical activity
