吸烟对在校大学生肺功能及健康体适能的影响

Effects of smoking on lung function and health fitness of college students

目的:探讨吸烟对在校大学生肺功能及健康体适能的影响。方法:通过方便抽样选取2020年9月30日在校的168名大学生作为研究对象,根据过去或(及)现在是否持续吸烟3年以上将其分为吸烟组66名(39.3%)与非吸烟组102名(60.7%),收集所有研究对象的一般人口学资料、身体成分、健康体适能以及肺功能测定等数据;比较两组健康体适能与肺功能的差异;分析吸烟组肺功能与健康体适能之间的关系,探讨用力肺活量(FVC)、第1秒用力呼气量(FEV 1)、呼气肺活量(EVC)的影响因素。结果:男性大学生吸烟组的峰值呼气流速(PEF)低于不吸烟组[(9.37±1.72)比(10.04±1.69)L/s](F=5.051,P=0.026);闭眼单脚站立时间长于不吸烟组[(87.2±49.1)比(63.6±39.7)s](F=9.327,P=0.003);女性大学生吸烟组每分钟仰卧起坐次数少于不吸烟组[(39.5±7.5)比(49.2±12.5)次/min](F=5.189,P=0.029)。吸烟组的肺功能指标中的峰值吸气流速(PIF)、FVC、FEV 1、EVC、PEF均与健康体适能测试项目握力、背肌力、仰卧起坐、俯卧撑、原地跳高、立定跳远能力呈正相关(均P<0.001);通过相关数据分析得出肺功能与健康体适能项目的估算关系式。结论:吸烟对在校大学生肺功能以及健康体适能会产生一定的危害。

Objective To explore the effects of smoking on lung function and physical fitness of college students.Method 168 college students on September 30,2020 were selected as the research subjects by convenient sampling.According to whether they had been smoking for more than 3 years in the past or(and)now,they were divided into smoking group(66 cases,39.3%)and non-smoking group(102 cases,60.7%).The general demographic data,body composition,health fitness and lung function of all the included subjects were collected,and the health status of the two groups were compared,the relationship between lung function and healthy physical fitness in the smoking group was analyzed,and the influencing factors of forced vital capacity(FVC),forced expiratory volume in the first second(FEV1)and expiratory vital capacity(EVC)were also analyzed.Results The peak expiratory flow rate(PEF)of male college students in smoking group was lower than that of non-smoking group[(9.37±1.72)vs(10.04±1.69)L/s](F=5.051,P=0.026).The standing time with eyes closed and one foot of smoking group was longer than that of non-smoking group[(87.2±49.1)vs(63.6±39.7)s](F=9.327,P=0.003).The number of sit ups per minute of female college students in smoking group was less than that in non-smoking group[(39.5±7.5)vs(49.2±12.5)times/min](F=5.189,P=0.029).The peak inspiratory flow rate(PIF),FVC,FEV1,EVC and PEF in the smoking group were positively correlated with grip strength,back muscle strength,number of sit ups,push ups,standing high jump and standing long jump(P<0.001);through the analysis of relevant data,the estimation formula of lung function and health fitness items was obtained.Conclusion Smoking is harmful to college students′lung function and physical fitness.
