海南省居民体质调查及其影响因素研究

目的探讨海南省居民体质指数（BMI）的分布特征及其与主要相关因素的关系。方法采用多阶段分层整群抽样方法随机抽取海南省36个居委会，村委会，1800个住户中的居民为调查对象，通过自制问卷实施入户调查及体测。结果样本人群BMI正常居民占60．1％，低体重或消瘦人群占31．9％，超重与肥胖人群占8％。男性BMI均值为20．6，女性BMI为21．0，男女BMI值均低于2000年全国水平，而均高于1992年海南省水平。Logistic回归分析分析，地区类型、城乡差异、年龄、职业、教育程度等因素为BMI的主要影响因素。结论海南省居民超重率呈上升趋势，在海南省营养不良、消瘦的情况比超重肥胖更加严重。海南省年轻人营养不均衡，必须注重主要影响因素的改善，加强健康教育。

Survey of health status of residnts in Hainan Province and its influencing factors

Objective To survey the distritution characteristics of BMI of residents in Hainan Province and the main relevant factors. Methods Multi-stage stratified and cluster sampling methods were utilized and 36 resident committees/ villagers' committees in Hainan were randomly chosen as the survey sites and residents in 1800 households were surveyed.. Results There 60.1% of the residents surveyed were with normal BMI and the rate of low-weighted or marasmus population were accounted for 31.9% ,while over-weighted and obesity polulation accounted for 8%. The average BM indexes of male and female were 20.6 and 21.0 respectively, both being lower than that of the whole country and higher than the level of Hainan Province in 1992. The rates of overweight and obesity increased with the improvement of education level. The results of Logistic regression analysis indicated that the type of regions, rural-urban differences, age, occupation and education level were the main influencing factors. Conclusion The overweight rate of Hainan residents shows an increasing trend. However, malnutrition and marasmus are more serious health problems than that of overweight and obesity in Hainan Province. Thus attention be paid to nutrition balance of the young in Hainan Province and effective measures inclduing health education be carried out.
