1
Values are means ± SDs unless otherwise indicated. P values were derived by using ANCOVA, adjusted for age. HAZ, height-for-age z score; WAZ, weight-for-age z score; WHZ, weight-for-height z score.
2
An age-adjusted Poisson regression model was used.
3
An age-adjusted logistic regression model was used.
