Abstract:Objective To preliminarily investigate the current status of dietary nutritional behavior in migrant children from Grades 4-6 in primary schools in Beijing, to analyze the multi-factors influencing the related behavior so as to provide evidence and guidance for further perfecting the targeted health education on dietary nutritional behavior and health promotion through schools, families and social environment. Methods A self-administered questionnaire was designed based on a large number of references. The stratified cluster sampling method was used to select 514 migrant children from Grades 4, 5 and 6 in 6 primary schools. A questionnaire survey was conducted under the the on-site guidance of the staff of the project. Results : A total of 514 effective questionnaires were retrieved, of which 59.92% were collected from migrant children of public schools and 40.08% from floating children schools. The average age of the migrant children was (11.48±1.125) years. 53.31% were boys and 46.69% girls. The formation rate of correct dietary nutritional behavior in the migrant children was low, and the score of the behavior was poor (the mean, the standard deviation and the median were 75.02, 13.77 and 75.67 respectively). Statistical analysis revealed that dietary nutritional behavior of the migrant children was significantly influenced by sex (P=0.030), types of schools (P=0.001) and economic condition of the family (P=0.006). Conclusions Sex, types of schools and economic condition of the family are the factors influencing dietary nutritional behavior of the migrant children; and hence, improving dietary nutritional knowledge in schools and among parents, especially in floating children schools and among parents with poor economic condition is an important measure for promoting the nutritional status of the migrant children.
