¥ NH: Nutrition and health; MA: Macronutrients; HFM: Household food measurement; FLN: Food label and numeracy; FG: Food group. ǂ For continuous data, values are median (IQR), and for categorical data, values are n (%). * For NH, MA, HFM and FLN: inadequate and marginal nutrition literacy (0 < score < 3); adequate nutrition literacy (4 < score < 6). For FG: inadequate and marginal nutrition literacy (0 < score < 10); adequate nutrition literacy (11 < score < 15) ** Significance pertains to chi squared or Mann-Whitney non-parametric test between 2 BMI categories: normal weight and overweight/obesity.
