OBJECTIVE: To determine the associations between meat, dairy and @entity219 intake and pubertal development in adolescents in Chengdu. METHODS: A total of 1320 @entity1 and adolescents aged 9-15 years in Chengdu were recruited using a stratified cluster sampling strategy. Dietary intake was assessed by the food frequency questionnaire (FFQ) and 3-day 24-hour dietary recall. Pubertal development was evaluated through physical examinations. Consumptions of meat and dairy, and @entity219 intake were compared between groups with different levels of pubertal development according to the Tanner criteria. RESULTS: The median age of spermarche was 13. 00 years. The @entity1 who had had spermarche consumed more meat (including red meat) and dairy products than those who had not yet (P<0. 05). Daily consumption of total meat was positively correlated with the level of pubertal development (P<0. 05). The median age of menarche was 12. 11 years. The @entity1 who had had menarche consumed more meat and less diiry products than those who had not yet (P<0. 05). Daily consumption of dairy products was negatively associated with breast development and the level of pubertal development (P < 0. 05). CONCLUSION: Consumptions of meat, red meat and dairy products are associated with pubertal development in adolescents in Chengdu. However, the differences between @entity1 and @entity1 warrant further studies.
