Associations between commonly consumed, uncommonly consumed, dichotomous dietary variables with overall urbanization index^*, CHNS 2015. A Commonly consumed foods (≥ 80% consumption). Relative risk ratios for associations between quintiles of intake and 1-standard deviation change in overall urbanization index^* among commonly consumed foods (≥ 80% consumption). ^* Urbanization index is a validated multicomponent measure of urbanization in the CHNS [6]. ^† The referent group was the lowest quintile, which included non-consumers, in unadjusted multinomial logistic regressions with overall urbanization index as the outcome. B Uncommonly consumed foods (< 80% consumers). Relative risk ratios for associations between quartiles of intake and 1-standard deviation change in overall urbanization index ^* among uncommonly consumed foods (< 80% consumers). ^*Urbanization index is a validated multicomponent measure of urbanization in the CHNS [6]. ^† Unadjusted multinomial logistic regressions with overall urbanization index as the outcome. C Dichotomous dietary variables. Odds ratios for associations between dichotomous dietary variables and 1-unit change in overall urbanization index^*. ^*Urbanization index is a validated multicomponent measure of urbanization in the CHNS [6]. ^†Unadjusted logistic regression models with overall urbanization index as the outcome
