title: [Cross-sectional association between overall diet quality and overweight/obesity among children and adolescents in Chengdu].
abstract: OBJECTIVE
  To develop Chinese Children Dietary Index, the overall diet quality of children and adolescents; the association between overall diet quality and overweight/obesity among children in Chengdu.
  
  
  METHODS
  Chinese Children Dietary Index was formulated based on the current Chinese Dietary Guidelines and Food Guide Pagoda for children and adolescents, consisting of 12 components. 1 997 children and adolescents aged 7-15 years in Chengdu were recruited and their diet quality was evaluated according to Chinese Food Guide Pagoda. Differences in percent body fat (PBF), fat mass index (FMI), fat-free mass index (FFMI) between 3 categories as low, moderate, and high diet quality, were tested.
  
  
  RESULTS
  The mean Chinese Children Dietary Index score for our population was 59.36 ± 11.50. The diet quality of 13-15 years old adolescents was the worst. 7-9 years old children with moderate diet quality had highest PBF (P = 0.04), while 10-12 years old children with higher diet quality had the lowest FFMI (P = 0.002).
  
  
  CONCLUSIONS
  The overall diet quality of children and adolescents in Chengdu could be reflected by Chinese Children Dietary Index. There was association between overall diet quality and overweight/obesity among children and adolescents. However, this association warrants more in depth evaluation in future studies.
