目的 了解血脂异常在青少年人群中的分布及影响因素。方法 以江门市棠下中学1 449名学生为研究对象,对其进行问卷调查、InBody人体成分仪检测和实验室检查。结果 血脂异常总检出率是8.3%,高胆固醇(TC)、高甘油三脂(TG)、高低密度脂蛋白胆固醇(LDL-C)和低高密度脂蛋白胆固醇(HDL-C)血症的检出率分别为8.3%、7.8%、10.6%和7.2%,女生血脂异常检出率(26.4%)高于男生(19.8%)(P<0.001);多因素分析显示性别(参照男性,OR=1.39,95%CI=1.08~1.80)和体脂百分比(参照正常组,超重、肥胖和重度肥胖组OR和95%CI分别OR = 1.62 / 2.89 / 4.45,95% CI = 1.13~2.32 / 1.85~4.51 / 2.48~7.96)与血脂异常间存在统计学关联(P<0.05)。结论 性别、体脂百分比是青少年血脂异常的影响因素。相对于青少年男生,青少年女生检出血脂异常的比例更高,体脂百分比高的青少年血脂异常的风险更高。

Objective To study the distribution and influencing factors of dyslipidemia among teenagers. Methods A questionnaire survey,InBody body composition test and laboratory examination were conducted on 1 449 students from the Tangxia Middle School in Jiangmen city as study objects. Results The total detection rate of dyslipidemia was 8.3% and the detection rates of high total cholesterol (TC),triglyceride (TG),high low-density-lipoprotein cholesterol (LDL-C) and low high-density-lipoprotein cholesterol (HDL-C) were 8.3%,7.8%,10.6% and 7.2%,respectively. The detection rate of dyslipidemia among teenage girls (26.4%) was higher than that among teenage boys (19.8%) (P<0.001). Multivariate analysis indicated that gender (with reference to male,OR=1.39,95%CI=1.08-1.80) and body fat percentage (with reference to normal group,for overweight,obesity and severe obesity groups,OR=1.62,2.89,4.45 and 95%CI=1.13-2.32,1.85-4.51,2.48-7.96,respectively) were statistically related to dyslipidemia (P<0.05). Conclusion Gender and body fat percentage are the influencing factors of dyslipidemia among teenagers. Compared with teenage boys,the teenage girls have a higher detection percentage of dyslipidemia. Teenagers with higher percentage of body fat show a higher risk of dyslipidemia.
