目的探讨农村社区居民体质指数(BMI)的分布现况及其BMI与慢性非传染性疾病(简称慢病)的关系,从而为慢病的早期预防提供依据。方法采用普查的方法,使用统一调查问卷对9 988名调查对象进行面对面调查。所有资料使用Epi Data 3.2录入,采用SPSS 13.0软件进行分析。率的比较采用χ2检验,P<0.01为差异有统计学意义。结果调查对象超重和肥胖的检出率年龄差异均有统计学意义(χ2=87.265,P<0.001;χ2=10.590,P<0.001),40～59岁年龄组超重和肥胖检出率均显著高于其他两个年龄组(P<0.001);超重和肥胖的检出率性别差异无统计学意义(χ2=2.294,P=0.134;χ2=0.003,P=0.976);超重和肥胖与高血压、糖尿病、血脂异常等慢病的发生密切相关,随着BMI的增加,上述疾病的检出率呈现出上升的趋势。结论超重组和肥胖组的高血压、糖尿病、血脂异常等慢病的检出率明显高于BMI正常组,提示为早期预防慢病,应特别关注BMI≥24的人群。
Objective To explore the distribution of body mass index (BMI) and the relationship between BMI and chronic non-communicable diseases (referred to as chronic disease) in rural community residents so as to provide the basis for early prevention of chronic diseases. Methods The method of census was used to survey 9 988 respondents with a unified questionnaire. All data were entered using Epi Data 3.2 and analyzed using SPSS 13.0 software. Rate comparison using χ2 test, P <0.01 for the difference was statistically significant. Results The detection rates of overweight and obesity among the surveyed subjects were statistically significant (χ2 = 87.265, P <0.001; χ2 = 10.590, P <0.001). The prevalence of overweight and obesity in the 40-59 age group was significantly higher There were no significant differences in the prevalence of overweight and obesity (χ2 = 2.294, P = 0.134; χ2 = 0.003, P = 0.976) in the other two age groups (P <0.001) Diabetes, dyslipidemia and other chronic diseases are closely related to the occurrence, with the increase of BMI, the detection rate of the disease showed an upward trend. Conclusion The detection rates of chronic diseases such as hypertension, diabetes and dyslipidemia in overweight and obesity groups were significantly higher than those in normal BMI group, suggesting that early prevention of chronic disease should pay special attention to those with BMI≥24.
