大学生饮食行为与肥胖关系分析

Association of Dietary Behavior with Obesity Among College Students

目的探讨大学生饮食行为与肥胖的关系,为大学生肥胖的预防工作提供科学依据。方法采用自编的饮食行为调查表,对中山大学南北校区1072名在校学生进行问卷调查,同时测量身高、体重、腰围,并计算体质量指数(BMI)。采用方差分析和协方差分析检验饮食行为与体质量指数和腰围之间的关系。结果多因素分析发现,进食辣味食品、快速进食、按价格择食等行为越多者的BMI、腰围趋向于越大。该3种行为多或较多者分别比少或较少者BMI增加3.0%,4.9%和2.4%,腰围增加2.9%,2.9%和2.2%;按口味择食、定时定量进食等行为多或较多者的BMI分别比少或较少者减少4.0%和4.1%,腰围减少2.2%和2.1%。结论少食辣味食品、减慢进食速度、不按价格择食、按口味择食和定时定量进食有助于大学生预防肥胖。
