超声评估脐区腹内脂肪厚度与肺功能的关系

目的探讨腹内脂肪厚度对肺通气功能参数的影响。方法选取医院2017年3月至2018年3月男性健康体检者155例,统计年龄、身高、体质量、体质量指数(BMI),利用超声测量腹内脂肪厚度,根据腹内脂肪厚度分为A组、B组和C组,并测量用力肺活量(FVC)、FVC测量值/预计值、第1秒用力呼气容积(FEV1)、1秒率(FEV1%)、呼气高峰流速(PEFR)、最大呼气中期流速(MMF)、50%流速(V50)等肺通气功能参数,比较各组间肺通气功能参数。结果各组年龄、身高经单因素方差分析结果显示,差异均无统计学意义(P>0.05);各组BMI经单因素方差分析结果显示,总体差异有统计学意义(P<0.05);将腹内脂肪及BMI进行相关性分析,两者有相关性(r=0.650,P<0.01);经单因素方差分析结果显示,各组FVC,FEV1,FEV1%,PEFR,MMF,V50比较,差异无统计学意义(P>0.05);不同腹内脂肪组FVC测量值/预计值经单因素方差分析结果显示,差异有统计学意义(P<0.05)。结论健康男性脐区腹内脂肪厚度与肺通气功能有关,有效控制腹内脂肪厚度对肺通气功能有利。

Objective To investigate the influence of intra-abdominal fat thickness on pulmonary ventilation function parameters.Methods Totally 155 healthy persons from March 2017 to March 2018 were examined.Age,height,weight were recorded,body mass index(BMI)was calculated,intra-abdominal fat thickness was measured by ultrasound.According to intra-abdominal fat thickness,they were divided into three groups:A,B and C.FVC,FVC measurement/predicted value,FEV1,FEV1%,PEFR,MMF and V50 were measured and compared among the 3 groups.Results There was no significant difference in age and height among different intra-abdominal fat groups(P>0.05).BMI of different intra-abdominal fat groups showed significant difference by one-way ANOVA analysis(P<0.05).Correlation analysis was made between abdominal fat and BMI,and there was correlation between them(r=0.650,P<0.01).There were no significant differences in FVC,FEV1,FEV1%,PEFR,MMF and V50 among the 3 groups(P>0.05).The FVC measurements/predictions of the 3 groups were statistically significant by oneway ANOVA analysis(P<0.05).Conclusion The thickness of abdominal fat in umbilical cord of healthy men is related to pulmonary ventilation function,and effective control of abdominal fat thickness is beneficial to pulmonary ventilation function.
