摘　　要：目的了解高职医学生体质指数以及肺活量体重指数现状,为大学生健康教育与健康促进工作的开展提供参考依据。方法采用整群抽样的方法,2020-10对某高职1552名大学二年级医学生进行身高、体重以及肺活量测量,计量资料采用t检验,计数资料采用χ^(2)检验,以P<0.05为差异有统计学意义。结果医学生中男女生正常体重占比分别57.40%和63.88%,差异有统计学意义。(χ^(2)=6.025,P=0.014);男、女生的低体重率分别为13.60%和18.73%,差异具有统计学意义(χ^(2)=6.290,P=0.012);男、女生超重率分别为20.40%和13.02%,肥胖率分别为8.60%和4.37%,男女生之间超重与肥胖率差异均有统计学意义(χ^(2)=14.158、11.204,P<0.01)。男、女生肺活量体重指数平均值分别为52.20 ml/kg和43.19ml/kg,差异具有统计学意义(t=14.651,P<0.001);男、女生的肺活量体重指数与BMI呈负相关(r=-0.449,P<0.01)。结论男生的超重(肥胖)率和女生低体重率较高,肺活量体重指数整体较低,应通过改善学生饮食、增加运动、改变不良生活行为方式等改进。Objective To understand the current situation of body mass index(BMI)and vital capacity weight index of medical students so as to provide a basis for the health work of college students.Methods A total of 1552 sophomores in a higher vocational college was selected by using a cluster sampling method.Height,weight and vital capacity of those students were measured.t-test was used for the measurement data and Chi-square test was used for the counting data and P<0.05 was considered as statistically significant.Results The prevalence rate of normal body weight in males was lower than that in females(57.40%vs.63.88%,χ^(2)=6.025,P=0.014).The prevalence rate of low weight in males was lower than that in females(13.60%vs.18.73%,χ^(2)=6.290,P=0.012).The prevalence rates of overweight in males and females were 20.40%and 13.02%,and the prevalence rates of obesity were 8.60%and 4.37%,respectively.There was statistical difference between the prevalence rates of overweight and obesity in different sexes(χ^(2)=14.158 and 11.204,P values<0.01).The mean values of vital capacity weight index in males were higher than that in females(52.20 ml/kg vs.43.19 ml/kg,t=14.651,P<0.001).The vital capacity weight index of medical students was negatively correlated with BMI(r=-0.449,P<0.01).Conclusion The prevalence rates of overweight and obesity in male students are higher than those in female students.The vital capacity weight index is low on the whole,which should be improved by changing students′diet,increasing their exercise,and changing their unhealthy lifestyle.
