WEN Dandan,GAO Sihai,CHEN Qingqing, et al. Status quo and influencing factors of malnutrition among primary and middle school students in Wenzhou[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2024, 54(2): 135-140.
Abstract：Objective: To investigate the current status of malnutrition among primary and middle school students in Wenzhou and explore its influencing factors so as to provid reference for the prevention and control of malnutrition. Methods: A total of 27 449 primary and middle school students in Wenzhou were selected in 2022 using a stratified cluster random sampling method. Physical examination and questionnaire survey were conducted on the participants to assess their nutritional status and analyze the factors influencing malnutrition.Chi-square was performed to analyze malnutrition-related factors and logistic regression was used for multivariate analysis. Results: The prevalence of malnutrition among primary and middle school students in Wenzhou was 7.59%, of which emaciation was dominant, accounting for 96.31%. The prevalence of malnutrition was higher in boys (8.49%) compared with girls (6.51%) (P<0.001). The prevalence of malnutrition in junior middle school students was the lowest (5.82%), and the prevalence in vocational high school students was the highest(10.54%) (P<0.001). Multivariate regression analysis showed that female students (OR=0.657, 95%CI=0.581-0.742), non-anemia (OR=0.734, 95%CI=0.626-0.860), fresh fruit intake frequency at 1 times per day (OR=0.783,95%CI=0.624-0.983) were protective factors against malnutrition. Conclusion: The malnutrition of primary and middle school students in Wenzhou is mainly manifested as emaciation. Gender, school stage, anemia, fresh fruit intake frequency, are the influencing factors of malnutrition. Further attention should be paid to malnutrition in boys and vocational high school students. Such interventions as balanced diet and cultivation of reasonable dietary habits should be carried out.
