目的了解海宁市农村成年居民肥胖流行特点,探讨肥胖测量指标与血脂异常的关系,为肥胖和血脂异常防控提供依据。方法通过多阶段分层整群抽样的方法,随机抽取4个镇(街道)居民1 475名进行问卷调查、体格检查及实验室检测,运用非条件Logistic回归模型评价肥胖测量指标BMI和WC与血脂异常的关系。结果海宁市农村居民肥胖患病率为6.58%;中心性肥胖患病率为33.63%;超重及肥胖人群TG、TC水平高于BMI正常人群,HDL-C水平均低于正常人群,血脂异常患病率均高于正常人群,差异均有统计学意义(P<0.01);BMI、WC与血脂异常呈正相关(P<0.01),BMI、WC每增加一个单位,血脂异常患病风险率分别增加9.30%和6.40%。结论海宁市农村居民肥胖和中心性肥胖患病率较高,BMI、WC与血脂异常患病密切相关,血脂异常患病风险随肥胖程度的增加而升高。
Objective To understand the prevalence of obesity among adult residents in rural Haining, and to explore the relationship between obesity measures and dyslipidemia and to provide evidence for the prevention and control of obesity and dyslipidemia. Methods A total of 1 475 residents from 4 towns (streets) were randomly selected for questionnaire survey, physical examination and laboratory test by multi-stage stratified cluster sampling method. The non-conditional logistic regression model was used to evaluate the relationship between obesity measurement index (BMI) and serum lipid Abnormal relationship. Results The prevalence of obesity in rural residents was 6.58% in Haining City. The prevalence of central obesity was 33.63%. The TG and TC levels in overweight and obese people were higher than those in normal BMI patients. The HDL-C levels were lower than those in normal subjects. (P <0.01). There was a positive correlation between BMI and WC and dyslipidemia (P <0.01). For each unit of BMI and WC, the prevalence of dyslipidemia was increased 9.30% and 6.40%. Conclusions The prevalence of obesity and central obesity in rural residents in Haining City is high. BMI and WC are closely related to the prevalence of dyslipidemia. The risk of dyslipidemia increases with the increase of obesity.
