  • The bold values represent statistically significant results.

  • *Model 1: unadjusted.

  • †Model 2: adjusted for age and sex.

  • ‡Model 3: adjusted for age, sex, migration background, living with a partner, education, income.

  • §Model 4: adjusted for age, sex, migration background, living with a partner, education, income, neighbourhood unemployment rate.

  • ¶ICC (SE) was estimated to be 0.02 (0.1) in the empty model.

  • ICC, intraclass correlation coefficient; RLQ, recreation location quotient.
