The nonlinear association of the number of years spent in a specific CVH with the risk of developing outcomes on follow-up. The restricted cubic splines model was used to flexibly model potential nonlinear association between the numbers of years spent in a specific CVH (0, 2, 4, 6, and 8) as a continuous variable and outcomes. The model was adjusted for age, sex, type of work, seat time, educational level, drinking status, family per-member monthly income, and history of diseases (hypertension, diabetes, and hyperlipidemia) CI confidence interval; CVD cardiovascular disease; CVH cardiovascular health; HR hazard ratio
