以皮褶厚度计算的体脂含量对冠心病和糖尿病患者及正常人肥胖的测定

Body fat content calculated by skinfold thickness in evaluating obesity in patients with coronary heart disease and diabetes mellitus and normal people

目的:采用测定皮褶厚度计算体脂含量的标准判定肥胖,并与体质量指数标准进行对比。方法:选择2003-05/09本溪钢铁有限责任公司总医院和本溪市中心医院循环内科住院及门诊治疗患者250例。其中糖尿病患者120例,男50例,女70例。冠心病患者130例,男80例,女50例,年龄50～65岁。同期选择的健康成人120人,男60人,女60人。采用国际通用的人体测量法,测量身高、体质量、肱三头肌部皮褶厚、肩胛下角部皮褶厚、髂前上棘部皮褶厚和小腿部厚皮褶厚6项指标。利用体脂含量和体质量指数法判定肥胖。男女性体质量指数≥25kg/m2为肥胖,男性体脂≥20%,女性体脂≥25%判定为肥胖。结果:按意向处理分析,370例均进入结果分析。①冠心病和糖尿病患者肱三头肌部皮褶厚、肩胛下角部皮褶厚、髂前上棘部皮褶厚和小腿部厚皮褶厚及体脂含量均大于健康组。②用体脂含量法判定肥胖,冠心病和糖尿病患者的肥胖比率均明显高于健康成人犤男性冠心病组56%(45/80);男性糖尿病组70%(35/50);女性冠心病组30%(15/50);女性糖尿病组27%(19/70);男性健康组20%(12/60);女性健康组8%(5/60),(χ2>6.63,P<0.01)犦。③采用体质量指数为标准判定肥胖的发生与体脂含量方法基本一致犤男性冠心病组54%(43/80);男性糖尿病组68%(34/50);女性冠心病组32%(16/50);女性糖尿病组27%(19/70);男性健康组20%(12/60);女性健康组8%(5/60),(χ2>6.63,P<0.01)犦。结论:冠心病和糖尿病患者的肥胖比例明显高于健康人,体脂含量标准与体质量指数标准对肥胖的判定基本一致。

AIM:To determine obesity with the standard of body fat content which is calculated by skinfold thickness,and compare with the standard of body mass index.METHODS:From May to September 2003,120 diabetic patients(50 males and 70 females) and 130 patients with coronary heart disease,who were treated or hospitalized in the Department of Cardiology,General Hospital of Benxi Iron and Steel Co.,Ltd and Benxi Central Hospital,and 120 healthy adults(60 males and 60 females) were selected in this study.International anthropometric method was used to measure body height,body mass,and skinfold thicknesses of triceps brachii muscle,subscapularis,anterior superior iliac spine and leg.Obesity was determined with body fat content and body mass index,the standard was that body mass index ≥ 25 kg/m2 for both males and females,body fat ≥ 20% for males and body fat ≥ 25% for females.RESULTS:According to intention to treat analysis,all the 370 cases were involved in the analysis of results.① The skinfold thickness and body fat of triceps brachii muscle,subscapularis,anterior superior iliac spine and leg in patients with coronary heart disease and diabetes mellitus were larger than those in the healthy group.② Obesity determined with body fat content showed that the obese rate was obviously higher in patients with coronary heart disease and diabetes mellitus than in healthy adults[56% (45/80) in male coronary heart disease group,70% (35/50) in male diabetes mellitus group,30% (15/50) in female coronary heart disease group,27% (19/70) in female diabetes mellitus group,20% (12/60) in male healthy group,8% (5/60) in male healthy group](χ 2 >6.63,P< 0.01).③ The occurrence rates of obesity determined with body mass index were almost the same with those with the method of body mass index[(54% (43/80) in male coronary heart disease group,68% (34/50) in male diabetes mellitus group,32% (16/50) in female coronary heart disease group,27% (19/70) in female diabetes mellitus group,20% (12/60) in male healthy group,8% (5/60) in male healthy group](χ 2 >6.63,P< 0.01).CONCLUSION:The proportion of obesity is obviously higher in patients with coronary heart disease and diabetes mellitus than in healthy people, and obesity determined with body fat content and body mass index is almost the same.
