目的探讨某高校女性教职工人群体质指数(BMI)、腰臀比(WHR)与脂肪肝等危险因素的相关性。方法对某高校2008年进行健康体检的1688名女性教职工的体检资料进行统计学分析,采用Logistic回归进行相关因素分析。结果女性教职工超重及肥胖率、中心性肥胖率及脂肪肝患病率分别为51.2%、34.4%、20.9%;随着年龄,BMI及WHR的增加,女性脂肪肝患病率均呈明显上升趋势(P<0.05);WHR和BMI均异常者脂肪肝患病率(49.3%)明显高于仅BMI异常者(25.9%)(P<0.05);多因素Logistic回归分析表明,WHR、总胆固醇TG、BMI、年龄是女性患脂肪肝的独立危险因素,相对危险度分别为646.073(95%CI=20.334～20527.555)、1.515(95%CI=1.347～1.703)、1.448(95%CI=1.365～1.536)、1.020(95%CI=1.005～1.035)。结论 WHR、BMI与高校女教职工脂肪肝的发生密切相关。
Objective To explore the correlation between body mass index (BMI), waist-hip ratio (WHR) and fatty liver in female college staff in a university. Methods The physical examination data of 1688 female staff in a university in 2008 were analyzed statistically. Logistic regression was used to analyze the related factors. Results The prevalence rates of overweight, obesity, central obesity and fatty liver in female teachers were 51.2%, 34.4% and 20.9% respectively. The prevalence of fatty liver increased significantly with the increase of age, BMI and WHR (P <0.05). The prevalence of fatty liver with abnormal WHR and BMI (49.3%) was significantly higher than that with only BMI (25.9%) (P <0.05). The multivariate logistic regression analysis showed that WHR, total cholesterol TG, BMI and age were independent risk factors for fatty liver in women. The relative risk was 646.073 (95% CI = 1.347-1.703), 1.448 (95% CI = 1.365 ~ 1.536), 1.020 (95% CI = 1.005 ~ 1.035). Conclusions WHR and BMI are closely related to the occurrence of fatty liver in female college staff in colleges and universities.
