Background: At present, limited information is available concerning the association between dietary patterns and cognitive ability during childhood and adolescence, especially in regards to the epidemiological studies in China. Therefore, This study aimed to analyze the association between dietary patterns and cognitive ability in 10 to 15 year-old Chinese children.
Methods: The dietary information, cognitive ability and sociodemographic data of 2029 children were retrieved from the 2010 China Family Panel Studies (CFPS). Dietary patterns were assessed by principal component analysis (PCA). The association between dietary patterns and cognitive ability was determined using Ordinal-Logistic regression models.
Results: Three dietary patterns were identified, namely, ‘High protein’, ‘High fat’ and ‘High salt-oil’. Following adjustment for gender, age, nationality, household registration, school types, parents’ education level, family learning environment, annual household income and family size, we found that an increase in ‘High protein’ pattern score was significantly associated with higher scores of mathematics test (OR=1.62, CI: 1.23~2.15; P=0.001), but not with those of vocabulary test (OR=1.21, CI: 0.93~1.58; P=0.149). Besides, an increase of ‘High fat’ pattern score was significantly associated with lower score of mathematics (OR=0.76, CI: 0.59~0.98; P=0.031) and vocabulary (OR=0.77, CI: 0.61~0.97; P=0.029) test. However, there was no significant association between ‘High salt-oil’ pattern and the score of mathematics (OR=0.99, CI:0.77~1.27; P=0.915) and vocabulary (OR=0.93, CI:0.73~1.18; P=0.544) test.
Conclusions: The findings of this study indicate that ‘High protein’ pattern is positively associated with cognitive ability in Chinese children, while ‘High fat’ pattern exhibits a negative association.
