| 摘 要： | 目的分析银川市城区中学生体重正常而体脂肪含量超标的隐性肥胖学生与体重正常且体脂肪含量正常学生心血管(cardiovascular,CV)危险因素间的差异,为早期识别中学生隐性肥胖及控制心血管代谢疾病提供理论依据。方法采用现况研究,以方便整群抽样的方法于2017-2018年共抽取银川市城区中学生1 043名,进行问卷调查、体格检查、体成分测定和血脂4项检测,并将体质量指数(BMI)正常的745名中学生作为研究对象。结果银川市城区中学生隐性肥胖检出率为31.1%。女生隐性肥胖检出率在不同年龄组均高于男生,差异均有统计学意义(χ^2值分别为10.37,106.49,P值均<0.01)。男生隐性肥胖组总胆固醇(total cholesterd,TC)高于正常组,而女生隐性肥胖组舒张压(diastolic blood pressure,DBP)、三酰甘油(trigly geride,TG)、TC和低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C)均高于正常组,差异有统计学意义(t值分别为-2.37,-3.82,-3.48,-4.46,-4.68,P值均<0.01)。女生隐性肥胖组血压偏高、高TC血症和高LDL-C血症的检出率均高于正常组,差异有统计学意义(χ^2值分别为4.17,8.77,5.91,P值均<0.05)。隐性肥胖组学生≥2项CV危险因素的检出率高于正常组,差异有统计学意义(χ^2=7.05,P<0.01)。结论银川市城区中学生隐性肥胖检出率较高,尤其是女生,隐性肥胖学生存在心血管危险因素代谢异常的比例高于正常学生。应及早采取干预措施进行防控。

| Abstract: | Objective To analyze the differences of cardiovascular(CV) risk factors between middle school students with normal weight but high body fat and students with normal weight and normal body fat in urban area of Yinchuan,to provide a theoretical basis for early detection of their invisible obesity and controlling CV metabolism disease. Methods During 2017 to 2018, a total of 1 043 secondary school students in urban area of Yinchuan were selected through cluster sampling. Questionnaire survey, physical examination, body composition and blood lipid test were conducted among all the participants.745 middle school students with normal body mass index(BMI) were included in the analysis. Results Nearly 31.1% students with normal BMI had high body fat, with girls significantly higher than that in boys across different age groups(χ^2=10.37,106.49,P<0.01). Total cholesterol(TC) in boys with normal-weight obesity was higher than that in the normal group, while diastolic blood pressure(DBP), triglyceride(TG), TC and low-density lipoprotein cholesterol(LDL-C) in girls with normal-weight obesity were significantly higher than that in the normal group, with statistically significant differences(t=-2.37,-3.82,-3.48,-4.46,-4.68,P<0.01). The detection rates of high blood pressure, high TC level and high LDL-C level in normal-weight obese girls were all higher than those in normal group(χ^2=4.17,8.77,5.91,P<0.05). The detection rate of CV risk factors ≥2 in normal-weight obesity group was higher than that in the normal group, and the difference was statistically significant(χ^2=7.05,P<0.01). Conclusion Normal-weight obesity among middle school students in urban area of Yinchuan is prevalent, which is mainly concentrated in female students. Moreover, cardiovascular risk factors are more common among those normal-weight obese students compared with normal students. Interventions for preventing and controlling normal-weight obesity should be developed and implemented as early as possible. |
