Data are centered at retirement: w₋₁, w₋₂, and w₋₃ refer to survey waves before retirement, and w₊₁, w₊₂ and w₊₃ refer to survey waves after retirement. ^a Change is estimated over 4 years of time. Model 1: adjusted for retirement age and socioeconomic position. Model 2: Model 1 + adjusted for physical activity, alcohol use and smoking as time-varying covariates and marital status, body mass index, number of chronic diseases and job strain before retirement
