Two-part regression models were run to estimates the extent of the association of each individual factor with the overall consumption amount in kcal from SSBs and milk when other factors were controlled for. Coefficient estimates from the two-part regression models are presented. Models also controlled for age as splines for adolescents, young adults, adults, and elderly, household size, residence in urban (with the reference group of rural residence, and survey round as a series of dummy indicators. The reference groups for household income and education group were bottom quartile of household income and less than high school. 95% confidence intervals are in brackets. Standard errors are in parentheses. * p< 0.05, ** p< 0.01.
