摘要
目的:调查沈阳市汉族医学生体成分与肺活量指标,并分析两者间的相关性。方法:选取沈阳某医学院校年龄19~21岁的汉族医学本科生1920例(男生710例,女生1210例)。使用人体成分分析仪和肺活量仪测量学生体成分指标及肺活量,采用逐步多元回归分析研究学生体成分指标与肺活量之间的关系。结果:汉族医学男生的体重指数、体重、总水分、骨矿含量及蛋白质含量均高于同组别女生(P<0.01),而女生的脂肪含量高于同组别男生(P<0.01)。逐步多元回归分析结果显示,沈阳汉族医学生中,脂肪含量(B<0,P<0.01)与蛋白质含量(B>0,P<0.01)是影响肺活量的主要体成分;这种影响在调整了性别后仍然存在。结论:脂肪增加与沈阳汉族医学生肺活量下降相关,蛋白质增加与沈阳汉族医学生肺活量升高相关,建议合理减脂,适当增肌,以维持正常肺活量水平。
Objective:To investigate the characteristics of body composition and vital capacity of Han medical students in Shenyang,and to analyze the correlation between them.Methods:A total of 1920 medical undergraduates(710 male and 1210 female,19-21 years old)of Han nationality were enrolled from a school in Shenyang.Body composition analyzer and spirometer were used to measure the body composition indexes and vital capacity of students,and the relationship between body composition indexes and vital capacity was analyzed by stepwise multiple regression analysis.Results:BMI,body weight,total body water,bone mineral mass and protein mass of male medical students of Han nationality were higher than those of female medical students(P<0.01),while the fat mass of boys was lower than that of girls(P<0.01).Stepwise multiple regression analysis showed that fat mass(B<0,P<0.01)and protein mass(B>0,P<0.01)were the main body components affecting vital capacity in students,and this effect still existed after adjusting for gender.Conclusions:The increase of fat mass is related to the decrease of vital capacity,and the increase of protein mass is related to the increase of vital capacity in Han medical students in Shenyang.It is recommended to reduce fat reasonably and build muscle appropriately to maintain normal vital capacity.
