Abstract： 本文旨在研究分析成年人去脂体重(fat free mass,FFM)、脂肪体重(fat mass,FM)和肺通气功能的关系.随机抽取黑龙江省部分地区19～81岁健康成年人群1307人(男性372人,女性935人),测量身高、体重,采用身体成分仪和肺功能仪分别检测FFM、FM和肺通气功能,并采用Pearson相关分析、独立样本t检验和多元逐步回归等统计学方法分析FFM、FM和肺通气功能的关系.结果显示,无论性别,年龄均与脂肪体重指数(FM index,FMI)呈正相关(P<0.001),去脂体重指数(FFM index,FFMI)和用力肺活量(forced vital capacity,FVC)、用力呼气一秒量(forced expiratory volume in one second,FEV1)、最高呼气流量(peak expiratory flow,PEF)、用力呼出25%肺活量时呼气流量(forced expiratory flow at 25%of forced vital capacity,FEF25%)均呈正相关(P<0.01),FMI和FVC、FEV1、FEF75%呈负相关(P<0.05).男性FMI和最大呼气中段流量(maximal mid-expiratory flow,MMEF)呈负相关(P<0.05).无论性别,FFMI对于FVC作用大于FMI,而对于FEV1,男性FMI作用大于FFMI,女性则反之.无论性别,FFMI升高,PEF和FEF25%也升高,而FMI对二者无作用.无论性别,FMI升高,FEF75%降低,而FFMI对其无作用.FMI升高,男性MMEF降低,女性无明显改变.本研究结果表明,FFM和FM均是影响肺通气功能的独立因素,反映骨骼肌力的FFM与肺通气功能呈正相关,FM与肺通气功能呈负相关.FFM和FM对肺通气功能作用大小存在差别.
