  • The mean (SD) was calculated for continuous variables. N (%) was for categorical variables. There were no missing data for any of the variables included in this study for all participants. The significance levels indicate the statistical significance of differences between trajectory group 1 and each of the other trajectory groups. Significance levels were *p<0.10; **p<0.05; ***p<0.01.

  • BMI, body mass index; CHD, coronary atherosclerotic heart disease; UEBMI, urban employee basic medical insurance; URRBMI, urban-rural resident basic medical insurance.
