^aModel 1 included energy intake and macronutrient composition in the quantile regression model to investigate the association with WC. ^bModel 2 adjusted for age (18-44y and 45-64y), education (primary/illiterate, junior and high school/above), income (low, medium and high), region (urban/rural) and physical activity (low, medium and high), current smoker (yes/no), current drinker (yes/no).^c ***, ** and * indicate statistical significance at the 1, 5 and 10% level, respectively. % E^{4, 5, 6} means the percentage of energy intake from fat, protein and carbohydrate, respectively
