体重指数与慢性疾病关系的研究

目的　探讨体重指数与糖尿病、冠心病、高血压、高脂血症等慢性疾病的相关关系。　方法　对 5 10例 45～ 66岁干部的健康体检资料进行分析。　结果　 48.8%的人超重 ,12 .5 %的人肥胖 ,仅有 3 7.1%的人体重正常。随着体重指数的增加 ,糖尿病、冠心病、高血压和高脂血症的患病率逐渐增加 ,患两种以上慢性疾病的人数比例也显著增加 ,肥胖组前三种疾病的患病率明显高于体重正常组。多因素 L ogistic回归分析 ,体重指数与冠心病、高血压呈显著正相关 ,OR值分别为1.416和 1.772。　结论　体重指数与冠心病、高血压呈显著正相关 ,肥胖是糖尿病、冠心病、高血压、高脂血症等慢性疾病的危险因素

The Relationship between Body Mass Index and Chronic Diseases

Objective To study the relationship between body mass index(BMI) and chronic diseases such as diabetes mellitus,coronary heart disease,hypertension,hyperlipidemia. Methods Analyse the data of a physical examination on 510 cadres aged 45-66 years old. Result The proportion of people with over body weight or obesity was 48.8% and 12.5% respectively. Only 37.1% of people had normal body weight.With the increasement of BMI,prevalence rate of diabetes mellitus,coronary heart disease, hypertension,hyperlipidemia increased gradually,and the proportion of people with more than two chronic diseases increased significantly. Prevalence rate of the first three diseases in obese group was significantly higher than that in normal group(P<0.05).Logistic regression analysis showed that BMI correlated with coronary heart disease and hypertension positively.OR was 1.416 and 1.772 respectively. Conclusion BMI correlated with coronary heart disease and hypertension positively. Obesity was a major risk factor for chronic diseases.
