2014年沈阳市沈北新区锡伯族与汉族初中生肺活量比较分析

Comparative Analysis on the Vital Capacity of Xibo and Han Ethnic Junior High School Students in Shenbei New District,Shenyang City,2014

目的本研究以沈北新区锡伯族学校的学生为研究对象,科学、全面评价和认识城市边缘地区以锡伯族为代表的学生的体质健康情况。方法于2014年3~5月采用整群抽样方法对沈阳市沈北新区2所乡村中学的425名初一到初三体重在40~100kg的初中学生常规体检调查资料进行调查分析。结果共调查425名锡伯族、汉族中学生,锡伯族中学生肺活量（均数±标准差）为（2 391.30±697.47）ml,男生（2 729.38±688.58）ml,女生（2 124.87±580.75）ml。汉族中学生肺活量为（2 290.54±692.34）ml,男生（2 566.65±650.51）ml,女生（1 768.40±445.74）ml。锡伯族中学生肺活量均高于汉族中学生（P〈0.01）;初二、初三年级锡伯族男生肺活量高于同年级汉族男生（P〈0.05）,初一~初三年级锡伯族女生肺活量均高于同年级汉族女生（P〈0.05）。锡伯族中学生肺活量体重指数（均数±标准差）为（43.92±12.51）,男生（49.12±11.53）,女生（39.82±11.74）,汉族中学生肺活量体重指数为（38.81±11.56）,男生为（43.94±10.51）,女生为（32.47±9.51）。锡伯族男女生肺活量体重指数均高于汉族男女生（P〈0.01）。初二、初三年级锡伯族男生肺活量体重指数高于同年级汉族男生（P〈0.05）,初一到初三年级锡伯族女生肺活量体重指数均高于同年级汉族女学（P〈0.05）。结论初二、初三年级锡伯族男生肺活量和肺活量体重指数均比汉族男生高。初一到初三年级锡伯族女生肺活量和肺活量体重指数均比汉族女生高。

Objective To understand the physical health status among the Xibo ethnic junior high school students,so as to provide scientific basis for working out standards for the health of students. Methods A cluster sampling method was applied to 425 high school students from Junior 1 to Junior 3,weighing 40-100 kg of 2 rural high schools in Shenbei new district for statistical analysis during March-May, 2014. Results Of 425 high school students surveyed including Xibo and H an ethnic, the vital capacity of Xibo students was （2 391.30± 697.47）ml （mean±SD）, in which the male＇s was （2 729.38±688.58）ml and the female＇s was（2 124.87±580.75） ml. The vital capacity of Han students was（2 290.54± 692.34）ml,in which the male＇s was（2 566.65±650.51）ml,the female＇s was（1 768.40±445.74）ml. The vital capacity of Xibo students was all higher than that of Han students（ P 〈0.01）. The vital capacity of Xibo male students in Junior 2 and Junior 3 was higher than that of Han male students in the same grades（ P 〈0.05）. The vital capacity of Xibo female students was higher than that of Han female students from Junior 1 to Junior 3（ P 〈0.05）. The vital capacity/BMI of Xi- bo students was（43.92± 12.51） （mean ±SD）, in which the male＇s was （49. 12± 11.53 ） and the female＇s was （39.82 ± 11.74）. The vital capacity/BMI of Han students was（38.81±11.56）in which the male＇s was（43.94± 10.51）and the fe- male＇s was（32.47±9.51）. The vital capacity/BMI of Xibo students was higher than that in Han students in both male and female groups. The vital capacity/BMI of Xibo male students in Junior 2 and Junior 3 was higher than that of Han male students in the same grades（ P 〈0.05）. The vital capacity/BMI of Xibo female students was higher than that of Han female students from Junior 1 to Junior 3 （ P 〈0.05）. Conclusion Both vital capacity and vital capacity/BMI of Xibo male studentsare higher are than those of Han male students in Junior 2 and Junior 3. Both vital capacity and vital capaci- ty/BMI of Xibo female students are higher than those of Han female students from Junior 1 to Junior 3.
