Objective Abdominal obesity is the initial factor of a series of metabolic disorders,therefore,the aim was to study the relation between abdominal obesity and inflammatory factor level,metabolic syndrome,and to provide the theoretical basis for the treatment of abdominal obesity. Methods A total of 85 cases of obese children were as subjects who were from the pediatric endocrine clinic of the Second Affiliated Hospital of Xi'an Jiaotong University from 2011 to 2012.According to the waist circumference,subjects were divided into abdominal obesity group and non-abdominal obesity group.Objects' height,weight,waist circumference and hip circumference were measured,fasting blood glucose,blood lipid,hs-CRP and visfatin levels were detected too. Results Body mass index(BMI),waist circumference,waist to hip ratio of abdominal obese children were significantly higher than those of non abdominal obese children (P<0.05);Abdominal obesity group of metabolic syndrome prevalence was higher than that in non abdominal obesity group (P<0.05);Comparison of children with abdominal obesity with non abdominal obesity,prevalence of hypertension,high blood sugar,high TG level and low HDL-C level had a statistical difference between the two groups;The level of C-reactive protein and visfatin levels were significantly higher than those in non abdominal obesity group. Conclusions Abdominal obesity children than non abdominal obesity are more likely to develop metabolic syndrome,and children with abdominal fat distribution more closely related to triglyceride and body inflammatory cytokines increased.Therefore,obesity,especially abdominal obesity should be actively prevented and controled.
