The odds ratio was adjusted for household wealth quintile, education of mother, geographical area and residential location. The same 10 categories were used in linear models as in categorical models. Categorical models and linear models fit the data equally well (all P > 0.10 in likelihood ratio test for categorical vs. linear model).
a Food variety score of nine or higher.
