[Correlation of dietary patterns and cognitive function among preschool children in Ma'anshan City in 2014-2015].

ABSTRACT

OBJECTIVE: To classify the dietary patterns in preschoolers and explore the correlation between dietary patterns and executive functions. METHODS: Between April 2014 and June 2015, 12363 preschoolers were selected from 91 kindergartens of Ma 'anshan City. The classification of dietary patterns and executive functions by Brief-P were evaluated. Unconditional binary logistics regression model was used to analyze the effects of different dietary patterns and executive functions in preschool chidlren. RESULTS: The higher the parents' education level, the lower the executive functions scores, the difference was statistically significant in preschoolers( P < 0. 05). The less intake of "processed model", "drinks model"and "snacks model", the more "vegetarian model"and "health model"intake, executive functions score was lower, and the difference was statistically significant( P < 0. 05). Logistic regression analysis showed that dietary patterns of"processed model"( OR = 1. 44, 95% CI 1. 20-1. 72), "drinks model"( OR = 1. 22, 95% CI 1. 03-1. 46) and "snacks model"( OR = 1. 28, 95% CI 1. 08-1. 52) were risk factors of cognitive functions, and the dietary patterns of "vegetarian model"( OR = 0. 80, 95% CI 0. 67-0. 95) and "health model "( OR = 0. 84, 95% CI 0. 71-0. 98) were protective factors. CONCLUSION: The present study suggests that cognitive functions might be closely related with dietary pattern. The more "vegetarian model"and "health model"intake, the better cognitive functions developed in preschool children.
