目的 探究武汉市某高校医学生饮食行为对肥胖的影响,为指导大学生改善不良饮食行为,降低肥胖风险提供依据.方法 2020年9-12月采取整群随机抽样方法抽取武汉某高校医学院学生,通过体成分分析仪收集身体质量指数(body mass index,BMI)、体脂率(percentage body fat,PBF)和腰围(waist circumference,WC)等肥胖指标,采用三因素进食问卷调查大学生认知限制性进食(cognitive restraint of eating,CR)、非控制性进食(uncontrolled eating,UE)和情绪性进食(emotional eating,EE)行为得分,多元线性回归和logistic回归分析饮食行为与肥胖之间的关联.结果 共纳入1 079名研究对象.根据BMI、PBF和WC诊断的肥胖率分别为5.28％、18.63％和19.27％,女生CR、UE和EE得分均高于男生.关联性分析显示,CR与BMI、PBF和WC呈正相关,EE与PBF呈正相关,并且在男生、女生和总人群中,CR均与PBF诊断的肥胖风险增加有关.女生EE与PBF和WC诊断的肥胖风险增加有关(OR=1.105,95％CI:1.013～1.205、OR=1.657,95％CI:1.011～2.726),男生CR与WC诊断的肥胖风险增加有关(OR=1.240,95％CI:1.035～1.285).结论 大学生肥胖患病率较高,以PBF和WC为标准的肥胖问题突出,且CR和EE可能增加患肥胖的风险.
Impact of eating behavior on obesity among medical students in a university in Wuhan City
Objective To explore the influence of dietary behavior on obesity amongst medical students in a university in Wuhan City,and to provide a basis for guiding college students to change poor eating behavior and reducing the risk of obesity.Methods A cluster random sampling method was used to select medical students from a university in Wuhan City from September to December 2020.Body composition analyzer was employed to measure obesity indexes like body mass index(BMI),percentage body fat(PBF)and waist circumference(WC).The Three-Factor Eating Questionnaire was applied to investigating the scores of awareness of behaviors like cognitive restraint of eating(CR),uncontrolled eating(UE)and emotional eating(EE)among college students.Multiple linear regression and logistic regression were used for analyzing the association between eating behavior and obesity.Results A total of 1,079 subjects were enrolled into this study.The obesity rates based on diagnosing obesity in accordance with BMI,PBF and WC were 5.28％,18.63％and 19.27％respectively.CR,UE and EE scores were all higher in female students than male ones.Correlation analysis revealed that CR was positively correlated with BMI,PBF and WC,and EE was positively related to PBF.Moreover,CR was associated with the increased risk of obesity diagnosed based on PBF in male and female students and the general population.EE was associated with the increased risk of obesity diagnosed based on PBF and WC in female students(OR=1.105,95％CI:1.013-1.205,OR=1.657,95％CI:1.011-2.726).CR was associated with the increased risk of obesity diagnosed based on WC in male students(OR=1.240,95％CI:1.035-1.285).Conclusion The prevalence rate of obesity among the college students is high,and the obesity problem diagnosed based on PBF and WC is prominent.CR and EE may increase the risk of suffering from obesity.
