1 Multivariable model
2 Final model including only the strongest predictors using a backwards selection procedure
3 Effect size was classified as minimal (OR <1.5), small (1.5 ≤ OR < 2), medium (2 ≤ OR < 3) or large (OR ≥ 3)
4 Reference group: age = 50–64 years; ethnicity = Native Dutch; marital status = married/cohabiting; education = high; perceived health = good; weight status = overweight; comorbidities = no comorbidities; physical activity = norm-active; income = high
