Objective To analyze the correlation between nutrition literacy and food choice among elementary and middle school students in Beijing．MethodsA cross-sectional survey was conducted from September 2020 to January 2021 using a multi-stage stratified cluster sampling method among 10000 students from 16 districts of Beijing. The "Nutrition Literacy Questionnaire for School-age Children" was used to collect information on nutrition literacy and "Food Frequency Questionnaire" was filled out to collect information on food intake. Both nutrition literacy and dietary behavior were scored, with the total score of nutrition literacy converted to a percentage. The students who scored more than 80 were defined as having nutrition literacy and were divided into two groups based on their nutrition literacy. The t-test was used to compare their dietary behavior scores, while chi-square test was used to compare the frequencies of various food intake. A multiple linear regression analysis with the eating behavior score as the dependent variable was conducted. Results For students in grades 3-12, only 11.7% had nutrition literacy. In terms of daily food intake, individuals with nutrition literacy had higher proportions of consuming breakfast daily, coarse grains, fruits, vegetables, dark-colored vegetables, dairy products, and soy products at rates of 93.8%, 44.8%, 82.4%, 89.0%, 67.0%, 66.6%, and 21.5% respectively. They also consumed mushrooms or algae, seafood, and animal livers at least once a week at rates of 88.0%, 80.7%, and 41.9% respectively, all of which were higher than those without nutrition literacy. Conversely, the proportions of consuming sugar-sweetened beverage, fried food and western fast food at least once a week were lower among individuals with nutrition literacy at 53.6%, 48.5%, and 40.0% respectively (P<0.05). Multiple linear regression analysis showed that the dietary behavior score was positively correlated with nutrition literacy (β=0.277,P<0.001). Conclusion The nutrition literacy levels of the surveyed students were relatively low, and those with higher levels of nutrition literacy usually chose foods in a healthier way.
