1) The p-values for differences across groups were calculated according to Bonferroni correction of multiple comparisons at alpha=0.05 using PROC SURVEYREG (*: p<0.05; **: p<0.01).
2) The p for trend obtained to trend as the levels of the predictor variable increase.
3) The means of daily nutrient intake were analyzed after adjusting for gender (male, female), age (19 − 39, 40 − 59, ≥60), education level (less than elementary school, middle school, high school, university or above), employment status (non-manual, manual, service, not working), household monthly income (quartile), BMI (<18.5, 18.5 − 24.9, ≥25), current diet control (yes, no), urban-rural status (urban, rural).

3) The means of food consumption frequency were analyzed after adjusting for gender (male, female), age (19 − 39, 40 − 59, ≥60), education level (less than elementary school, middle school, high school, university or above), employment status (non-manual, manual, service, not working), household monthly income (quartile), BMI (<18.5, 18.5 −24.9, ≥25), current diet control (yes, no), urban-rural status (urban, rural).

Data are expressed as unweighted frequency and weighted percentage or mean.
p-value was obtained from the Rao-Scott χ2 test for categorical variables and Bonferroni correction of multiple comparison for continuous variables.
