The correlations between dietary patterns and BMI, waist circumference and waist-hip ratio were analyzed by multiple regression analysis. Results The detection rates of BMI, waist circumference and waist-to-hip ratio were 32.4%, 36.64% and 30.42% respectively, all of which showed an increasing trend with age. Factor analysis of the six dietary patterns more meaningful, namely, the traditional model, high-salt mode, fruit and milk model, vegetarian mode, snack mode and alcohol mode. After multiple regression analysis, after adjusting for age, high-oil salt pattern was positively correlated with BMI and waist circumference.
