Results from logistic regression analyses for ‘twice’ participation in group-based physical activity programmes (reference group ‘once at t0’ participated in group-based physical activity programmes). CI, confidence interval. Ref., reference group. Significant associations are shown in bold and as *p < 0.05, **p < 0.01, and ***p < 0.001. Model 1 included sex, age, education and income at t0 and age and income at t1 (sex and education were assumed to be constant for persons over 30 years); Model 2 included Model 1 variables plus sports activity at t0 and t1; Model 3 included Model 2 variables plus subjective health status at t0 and t1; Model 4 included Model 3 variables plus physician physical activity counselling at t0 and t1
