超声探测脐区皮下脂肪厚度与肺功能的关系

Relationship between subcutaneous fat thickness measured by ultrasound on umbilical region and lung function

目的探讨超声探测脐区皮下脂肪厚度与肺功能的关系。方法体检健康者312例,超声探测其脐上1 cm处皮下脂肪厚度,并根据其厚度分为5组,A组72例,厚度≤5.0 mm;B组95例,厚度5.1～10.0 mm;C组65例,厚度10.1～15.0 mm;D组42例,厚度为15.1～20.0 mm;E组38例,厚度≥20.1mm。测量用力肺活量（FVC）、第1秒用力呼气容积（FEV1.0）、1秒率（FEV1.0/FVC）、最大自主通气量实测值（MVV实测值）、最大自主通气量预计值（MVV预计值）及最大自主通气量实测值/预计值（MVV实测值/预计值）。结果 1男性B组为优势组。与B组比较,D组FVC、FEV1.0、FEV1.0/FVC及MVV实测值均减低,E组FVC、FEV1.0、FEV1.0/FVC、MVV实测值及MVV实测值/预计值均减低（均P〈0.05）。E组MVV自身实测值/预测值〈70%呈低肺功能状态。2女性A组、B组及C组肺功能较好,但无明显肺功能优势组。与A组、B组及C组比较,D组FEV1.0、FEV1.0/FVC减低,E组FVC、FEV1.0、FEV1.0/FVC、MVV实测值及MVV实测值/预计值减低（均P〈0.05）。D组、E组MVV自身实测值/预计值〈70%,呈低肺功能状态。结论男女性脐区脂肪不同厚度均与肺功能有关,有效控制腹部脂肪厚度及腰围对肺功能有利。

Objective To investigate the relationship between subcutaneous fat thickness measured by ultrasound on umbilical region and lung function. Methods The subcutaneous fat thickness of 312 health examination people was measured by ultrasound 1 cm above the umbilical region. The people were divided into five groups according to the fat thickness： group A（72 cases, thickness ≤5.0 mm）, group B（95 cases, thickness 5.1～10.0 mm）, group C（65 cases, thickness 10.1～15.0 mm）,group D（42 cases, thickness 15.1～20.0 mm）, group E（38 cases, thickness≥20.1 mm）. The lung function parameters, such as the forced vital capacity（FVC）, forced expiratory volume in one second（FEV1.0）, forced vital capacity rate of one second（FEV1.0/FVC）,maximal voluntary ventilation measured value [MVV（measured）], maximal voluntary ventilation expected value [MVV（expected）] and MVV（measured）/ MVV（expected）（MVV%） were measured. Results 1 In men, the lung function was dominant in group B. Compared with group B, the FVC, FEV1.0, FEV1.0/FVC, MVV（measured） all were decreased in group D, FVC, FEV1.0, FEV1.0/FVC, MVV（measured）, MVV（%） were decreased in group E,all had statistical difference（P0.05）. Group E was at low lung function states with MVV% 70%.2In women, better lung function was found in group A,B and C, there was no statistical difference between the groups. Compared with group A, B and C,FEV1.0,FEV1.0/FVC were decreased in group D, FVC, FEV1.0, FEV1.0/FVC, MVV（measured）, MVV（%） all were decreased in group E,all had statistical difference（P0.05）. Group D and E were at low lung function states with MVV% 70%. Conclusion The subcutaneous fat thickness on umbilical region is correlated with lung function in men and women, effective control of abdominal fat thickness and waist circumference is beneficial to lung function.
