摘要:
了解焦作市隐性肥胖中学生心血管代谢指标与正常中学生之间的差异,为对隐性肥胖中学生采取干预措施提供支持.方法 在焦作市2所中学以班级为单位随机抽取635名中学生进行身体、体成分和代谢生化指标的测试,将BMI正常的384名中学生作为研究对象,对其中138名男生体脂肪率>20%、女生>25%的学生作为隐性肥胖组,与246名正常中学生各指标进行比较.结果 中学生隐性肥胖率为36.20%.隐性肥胖组中学男生的三酰甘油、总胆固醇、低密度脂蛋白均高于正常组学生,差异均有统计学意义(t值分别为-4.913,-3.116,-2.852,P值均<0.01);隐性肥胖组女生总胆固醇、低密度脂蛋白高于正常组学生,差异均有统计学意义(t值分别为-2.001,-3.481,P值均<0.05).隐性肥胖中学男生的高三酰甘油血症发生率高于正常组学生,差异有统计学意义(x2=7.352,P<0.01);隐性肥胖组女生高总胆固醇血症和高低密度脂蛋白血症的发生率高于正常组学生,差异均有统计学意义(x2值分别为4.394,4.626,P值均<0.05).结论 焦作市中学生隐性肥胖的比例较高,并且存在一定比例的血脂代谢异常学生,应进行控制和预防.
Abstract:
Objective To understand the differences of cardiometabolic indexes between middle school students with recessive obesity and normal weight in Jiaozuo city,and to provide specific intervention for recessive obese adolescents.Methods A random sample of 635 middle school students were selected from 2 middle school in Jiaozuo city.Physical examination,body composition and metabolic biochemical test were carried out.All the 384 middle students with normal BMI were included.Among them,138 students of boys with body fat percent >20% and girls with body fat percent >25% were defined as recessive obesity group,which were compared with the rest of 246 students.Results Recessive obesity among middle school students was 36.20%.Total cholesterol,low-density lipoprotein cholesterol (HDL-C) in recessive obese boys were significantly higher than the normal group(t =-4.913,-3.116,-2.852,P<0.01);The total cholesterol and LDL among recessive obese girls were higher than the normal group(t=-2.001,-3.481,P<0.05).The prevalence of hypertriglyceridemia was significantly higher in recessive obese boys than that of the normal group(x2 =7.352,P<0.01).The prevalence of high total cholesterol and hyper-low density lipoproteinemia in recessive obese girls was significantly higher than normal group(x2 =4.394,4.626,P<0.05).Conclusion There is a high proportion of middle school students with recessive obesity and dyslipidemia in Jiaozuo city,which should be controlled and prevented.
