OBJECTIVES
This study aimed to identify dietary knowledge, attitudes, and behaviors related to obesity and highly underweight among urban Chinese high school students.
METHODS
Using the data of 403 high school students from a cross-sectional survey in 2022, multinomial logistic regression analysis was conducted with the body mass index as the objective variable (reference: normal weight), dietary knowledge, attitudes, and behaviors as the explanatory variables, adjusted for sex.
RESULTS
Both obesity and highly underweight were most strongly related to incorrect dietary knowledge of desirable types of diets. Additionally, obesity was related to inappropriate dietary attitudes regarding the importance of diet, eating at irregular meal-times, and eating without chewing well, while highly underweight was related to picky eating and not having three meals per day, but not related to attitudes.
CONCLUSION
The incorrect knowledge of desirable type of diet was related to both obesity and highly underweight, while other risk factors of knowledge, attitudes, and behaviors related to obesity or highly underweight differed respectively. These findings should be useful in examining effective nutrition education for urban Chinese high school students.
目的
本研究旨在识别与城市中国高中生肥胖和极度消瘦相关的饮食知识、态度和行为。
方法
利用 2022 年一项横断面调查的 403 名高中生数据，以体重指数为因变量（参照：正常体重），以饮食知识、态度和行为为解释变量，进行多变量逻辑回归分析，调整性别因素。
结果
肥胖和极度消瘦与理想饮食类型的不正确饮食知识关系最密切。此外，肥胖与饮食重要性、不定时进餐和不好好咀嚼的不当饮食态度有关，而极度消瘦与挑食和不定时进餐有关，但与态度无关。
结论
理想饮食类型的错误知识与肥胖和极度消瘦都有关，而肥胖或极度消瘦相关的知识、态度和行为的其他风险因素则不同。这些发现对于检查城市中国高中生有效的营养教育应该是有用的。
