Background Limited study is currently available concerning the associations between dietary patterns and cognitive ability during childhood and adolescence, especially studies come out of Chinese data. Our aim was to analyze the associations between dietary patterns and cognitive ability in 10 to 15 year-old Chinese children. Methods 2029 children's dietary, cognitive ability and sociodemographic data were available from the 2010 China Family Panel Studies (CFPS). Dietary patterns were

Results Three dietary patterns were identified namely as 'High protein', 'High fat' and 'High salt-oil'. Following adjustment for the gender, age, nationality, household registration, school, parents' education, family education environment, family annual income and family size, we found that higher score on the 'High protein' pattern was associated with higher scores of mathematics test (OR=1.62; CI: 1.23~2.15; P=0.001) but was not significant with vocabulary test (OR=1.21; CI: 0.93~1.58; P=0.149). Higher score on the 'High fat' pattern was associated with lower score of mathematics (OR=0.76; CI: 0.59~0.98; P=0.031) and vocabulary test (OR=0.77; CI: 0.61~0.97; P=0.029). There was no significance between 'High salt-oil' pattern and mathematics (OR=0.99; CI:0.77~1.27; P=0.915) and vocabulary test (OR=0.93; CI:0.73~1.18; P=0.544). Conclusions The study indicated that 'High protein' pattern may has positive associations with cognitive ability in Chinese children, while 'High fat' pattern may has negative associations.
