摘　　要：目的:了解医学院校新生体质指数(BMI)现状,并对其相关影响因素进行分析。方法:对昆明医科大学2011级学生进行自身健康评估、营养知识、饮食行为、每周运动等情况开展问卷调查。结果:18.5≤BMI<24为标准体重指数,体重过轻(BMI<18.5)的占16.3%,超重(24≤BMI<28)的占5%,肥胖(28≤BMI)的占1.9%;女生体形偏瘦的人数明显多于男生(χ2=5.842,P=0.016),而肥胖的人数比男生少(χ2=11.852,P=0.001);城市与农村学生BMI指数存在统计差异(χ2=21.215,P<0.001);该群体的BMI指数与自身体重的认知态度(P<0.001),尝试控制体重的行为(P=0.032),每周做运动的频率(P=0.005),三餐习惯(P=0.031),是否吸烟(P<0.001),饮酒频率(P=0.005)有关。结论:应提高医学院校新生对自身体重的认知,增强体育锻炼以及合理饮食,培养良好的生活习惯。Objective To study the status of BMI of freshmen in medical colleges, and analyze its influencing factors.
