中文摘要：

目的研究深圳市成人体质指数（BMI）和腰围（WC）与血脂各组分的水平及其脂代谢异常风险之间的相关性。方法按照多阶段分层整群随机抽样法,从深圳市8个行政区中抽取12个社区,每个社区随机抽取75户常住居民进行入户调查、体格检查和血脂测定。结果不同BMI组和不同腰围组的TG、TC、HDL-c、LDL-c水平的差异有统计学意义（P〈0.05）,单因素线性回归分析发现,随着BMI和WC的增加,TG、TC、LDL-c水平均呈递增趋势（P〈0.05）,HDL-c水平均呈递减趋势（P〈0.05）;多因素logistic回归结果表明,随着BMI的增加,罹患高TG、高TC、低HDL-c、高LDL-c和血脂异常的风险呈增加趋势（P〈0.05）,随着WC的增加,罹患高TG、高TC、高LDL-c和血脂异常的风险呈增加趋势（P〈0.05）;偏相关分析结果显示,BMI与HDL-c的相关性比WC大（P〈0.05）,WC与TC的相关性比BMI大（P〈0.05）。结论体质指数和腰围与血脂各组分的水平独立相关,高体质指数和腰围是血脂各指标异常的危险因素。

英文摘要：

Objective To study the relationship between the body mass index（BMI）,waist circumference（WC） and lipids levels,dyslipidemia among adults.Methods Totally 12 communities from 8 districts were sampled through stratified randomized sampling,75 households from each community were sampled by random sampling for questionnaire survey,physical examination and laboratory tests.Results Within different BMI categories,the triglyceride（TG） in higher BMI group were higher than in lower BMI group,and the high density lipoprotein-c（HDL-c） in higher BMI group were lower than in higher BMI group;Within different WC categories,the TG,total cholesterol（TC）,low density lipoprotein-c（LDL-c） in higher WC group were higher than in lower WC group.With the increase of BMI/WC,the levels of TG,TC and LDL-c showed a rising trend（P0.05）,HDL-c showed a falling trend（P0.05）.With the increase of BMI,the odds ratios（ORs） of high TG,high TC,low HDL-c,high LDL-c and dyslipidemia showed a rising trend（P0.05）,and with the increase of WC,the ORs of high TG,high TC,high LDL-c and dyslipidemia showed a rising trend（P0.05）.There were positive partial correlations between BMI/WC and TG,TC,HDL-c,LDL-c.HDL-c had a higher correlation with BMI（P0.05）,TC had a higher correlation with WC（P0.05）.Conclusion BMI and WC were independently associated with blood lipids levels,and high BMI and WC were the risk factors for dyslipidemia.
