Data was expressed as mean±standard errors for categorical variables.

Q, quartile; RE, retinol equivalents.

The carbohydrate intake and protein intake proportions were calculated: carbohydrate intake (g/day)×4 kcal/total energy intake (kcal/day)×100 and protein intake (g/day)×4 kcal/total energy intake (kcal/day)×100. The fat intake proportions were calculated: fat intake (g/day)×9 kcal/total energy intake (kcal/day)×100.

P-values are calculated using a weighted one-way analysis of variance.
