目的探讨广州健康体检人群中作为腹型肥胖指标的腰身指数(腰围/身高比值WHtR)与心血管病危险因素的相关性。方法对2003年3月~2006年12月入广州疗养院体检的广州市各类人员共1 536人测量和检测身高、体质量、腰围、血压、心率、生化等指标,并进行统计学分析。结果WHtR随年龄增大而增高;WHtR异常组的年龄、体质量、SBP、DBP、FBS、TC、TG以及尿酸均显著高于WHtR正常组,HDL-C的结果则相反(P<0.01);同时WHtR与年龄、体质量、SBP、DBP、FBS、TC、TG呈显著正相关、与HDL-C呈显著负相关(P<0.05,P<0.01)。结论WHtR可作为有效的腹型肥胖参考指标,WHtR异常者其心血管病危险因素水平比正常者高。
Objective To investigate the correlation between waist circumference index (WHtR) and risk factors of cardiovascular disease as a marker of abdominal obesity in Guangzhou health examination population. Methods A total of 1 536 people in Guangzhou from March 2003 to December 2006 were enrolled in Guangzhou Sanatorium for physical examination. Height, body weight, waist circumference, blood pressure, heart rate and biochemical indexes were measured and analyzed. Results The WHtR increased with age. The age, body weight, SBP, DBP, FBS, TC, TG and uric acid in the WHtR abnormal group were significantly higher than those in the normal WHtR group (P <0.01). WHtR was positively correlated with age, body weight, SBP, DBP, FBS, TC, TG, and had a significant negative correlation with HDL-C (P <0.05, P <0.01). Conclusions WHtR can be used as a valid reference for abdominal obesity. Patients with abnormal WHtR have higher risk of cardiovascular disease than normal subjects.
