Notes: ^p < 0.1, *p < 0.05,**p < 0.01, ***p < 0.001. aAdjustments made for baseline characteristics: age, sex, health condition and health score. bSignificance refers to the difference between the group and the reference category (voluntary retirees). cSignificance refers to whether there was a change in the group’s health or physical activity. On all scales higher scores represent better health/ more physical activity
