title: [Cross-sectional association between foods rich in protein and body composition among children and adolescents in Chengdu City].
abstract: OBJECTIVE
  To examine the association between foods rich in protein and body composition among children and adolescents in Chengdu.
  
  
  METHODS
  With cluster sampling, a total of 2029 children and adolescents aged 7 - 15 years were recruited in Chengdu as the participants. Information about consumption of foods rich in protein was collected from food frequency questionnaire and anthropometric measurement was conducted to calculate the indices of body composition, percentage of body fatness (BF%), fat mass index (FMI) and fat free mass index (FFMI). Wilcoxon signed rank test was used to compare BF%/FMI/FFMI between food intake groups.
  
  
  RESULTS
  Among boys, compared with moderate and higher intake group of red meat, BF% was higher in the low intake group (P <0. 05). FFMI was highest in the higher intake group of red meat and white meat, however, in the lower egg intake group, FFMI was highest (P < 0. 05). Among girls, BF% and FMI were higher in the lower intake group of bean, fish, egg, dairy and dairy product than the moderate and high intake group (P <0. 05). FFMI was positively associated with consumption of red meat and was highest in-the lower intake group of egg and dairy (P <0. 05).
  
  
  CONCLUSIONS
  Red meat intake is positively associated with fat free mass in boys and girls. Only in girls, the consumption of bean/fish/egg/dairy and dairy product is primarily associated with fat mass. The different influence between genders needs to be further studied.
