  • Survival time ratio for each SES shift pattern was adjusted for baseline age, gender, BMI group, marital status, region of residence, smoking status, alcohol consumption status, self-rated health status, family history of cardiovascular diseases, diagnosis of hypertension, diagnosis of diabetes mellitus, total daily physical activity and baseline SES.

  • BMI, body mass index; SES, socioeconomic status.
