Comparison of cardiometabolic indexes between recessive obesity and normal weight middle school students in Jiaozuo city

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.
