目的 探讨浙江省非超重成年人血脂异常流行特征及影响因素.方法 选择参加2010年浙江省代谢综合征流行病学调查的10 868名年龄≥18周岁非超重/肥胖居民(BMI＜24.0 kg/m2)为研究对象,进行问卷调查、体检和血脂检测,采用多因素logistic回归模型分析影响因素.结果 该人群血脂异常患病率为41.38％,男性(43.19％)显著高于女性(39.84％)(x2=12.53,P＜0.001);随年龄增长,男性血脂异常患病率降低(趋势x2=47.61,P＜0.001),女性患病率升高(趋势x2=3.88,P＜0.05),＜50岁男性患病率明显高于女性;农村人群患病率(41.49％)略高于城市(41.21％),但差异无统计学意义(x2=0.08,P=0.774);多因素logistic回归分析显示,性别、慢性病家族史、现在吸烟、现在饮酒、高肉蛋类饮食、烹调使用动物油、体力活动、中心性肥胖和BMI是非超重成年人血脂异常的影响因素.结论 浙江省非超重成年人血脂异常患病率较高,家族史、吸烟、高脂饮食、体力活动不足、中心性肥胖等是主要影响因素.

Objective To understand the prevalence of dyslipidemia among non-overweight adults and related factors in Zhejiang province.Methods A total of 10 868 non-overweight adults (aged ≥ 18 years and BMI＜24.0 kg/m2) included in a population-based cross-sectional survey on metabolic syndrome in Zhejiang province in 2010 were selected to conduct questionnaire survey,health examination and blood fat detection.Results The overall prevalence of dyslipidemia in this population was 41.38％.The prevalence was significantly higher in males (43.19％) than in females (39.84％) (x2=12.53,P＜0.001).The prevalence of dyslipidemia significantly decreased in males (trend x2=47.61,P＜0.001) but increased in females (trend x2=3.88,P＜0.05) with age.There was no significant difference in the prevalence between urban area (41.21％) and rural area (41.49％) (x2 =0.08,P =0.774).Multiple logistic regression analysis showed that sex,family history of chronic diseases,smoking,alcohol use,high meat and egg diet,cooking with animal oil,physical activity,central obesity and BMI were factors related to prevalence of dyslipidemia.Conclusion The prevalence of dyslipidemia was high among the non-overweight adults in Zhejiang,and family history,smoking,high-fat diet,physical inactivity,central obesity seemed to be the major risk factors.
