Outline
To understand the current status of nutrition and health knowledge among primary and secondary school students in Anhui Province, analyze its influencing factors, and provide a basis for conducting nutrition and health education.
In 2024, a multistage stratified cluster random sampling method was used to investigate grades 4 to 6 and junior middle school students in 8 counties/districts in Anhui Province. The total score of the questionnaire was 100. The total of 75 or above indicated having knowledge of nutrition and health.A score of over 75% in each dimension was required to be considered as having nutritional health knowledge in that dimension. Binary logistic regression was used to analyze the influencing factors of nutrition and health knowledge among students.
A total of 2 225 primary and secondary school students were surveyed, including 1 074 girls (48.27%) and 1 018 primary school students (grades 4 to 6) (45.75%). The awareness rate of middle school students was relatively low in the two dimensions of dietary recommendations (24.58%) and food classification and characteristics (46.61%). Multivariate analysis showed that female (OR=1.346, 95%CI: 1.136-1.595), urban students (OR=1.224, 95%CI: 1.018-1.471), junior high school students (OR=1.500, 95%CI: 1.265-1.778), and having a mother with a college degree or above (OR=1.881, 95%CI: 1.347-2.627) were the positively correlated factors of students’ nutritional health knowledge.
Anhui Province’s primary and secondary school students have lower awareness rates of nutrition and health knowledge in the dimensions of dietary recommendations and food classification and characteristics. Gender, urban-rural residence, grade level, and the mother’s educational level are the main factors influencing students for the awareness rate of nutrition and health knowledge among primary and secondary school students. Health education should be conducted for different students and in different aspects of nutrition and health knowledge.
