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.

目的 探讨体感音乐疗法对青少年视疲劳患者症状缓解的影响。方法 选择青少年视疲劳患者72例,随机分为观察组和对照组各36例,两组患者均给予矫正用眼习惯、多运动、均衡饮食等护理,观察组在此基础上给予体感音乐疗法,3个月后比较两组视疲劳症状缓解情况。结果 干预后观察组视疲劳症状缓解程度及症状评分优于对照组,两组比较差异有统计学意义(P＜0.05)。结论 对青少年视疲劳患者实施体感音乐疗法,可起到促进眼部肌肉放松,改善微循环,增强睫状肌收缩力,改善虹膜睫状体调节功能,缓解视疲劳的效果。

Objective To explore the influence of vibroacoustic therapy on visual fatigue teenagers. Methods 72 visual fatigue teenagers were randomly and equally divided into the observation group and the control group. Both groups were accepted nursing in terms of the correction of eye habits, doing more sports and balanced diet, while the observation group was also accepted vibroacoustic therapy. After three months the conditions of these two groups in terms of visual fatigue were compared. Results After the intervention the degree of visual fatigue relief and the score of symptoms in the observation group were higher than those in the control group, and these differences have statistic significance (P＜0.05). Conclusion Vibroacoustic therapy can help visual fatigue teenagers to relax muscles of eyes, improve microcirculation, strengthen ciliary muscle contractile force, improve the regulatory function of iris ciliary and relieve visual fatigue.
