Model 1 was adjusted for age at baseline or at particular follow-up and sex

Model 2 was additionally adjusted for socio-economic status, education, smoking status, diagnosis of stroke, myocardial infarction, diabetes mellitus type 2 and cancer, total daily energy intake, daily alcohol intake

Outcome variable was dichotomized (active and inactive).

¹All p-values were <0.001

²Estimates were obtained from mixed logistic regression model with random effects taking into account repeated measurements of exposure, outcome and covariates in the same model. Information on dietary covariates was not available for the 18-month and the 10-y follow-up. In the mixed model we considered total daily energy intake and daily alcohol intake from baseline and from the second health check which took place 3 y after baseline.
