Abstract:
Objective To investigate intestinal bacteria genera distribution between normal weight and overweight/obesity school-age children in Yili region of Xinjiang.Methods Selecting eligible 150 fecal samples from school-age children (aged from 7 to 13 years old),all samples were divided into normal weight group and overweight/obesity group according to the body mass index (BMI),and each group contained 75 samples.Fecal samples were collected and DNA was extracted,then 6 types of intestinal bacteria genera were detected by the quantitative real-time polymerase chain reaction.Results The distribution of age,gender,ethnicity and hip circumference between 2 groups had no statistically significance (all P ＞ 0.05),except that of BMI and waist circumference (t ＝ 20.740,8.533,all P ＜ 0.01).The concentration of Lactobacillus,Clostridium and Enterococcus were significantly higher in the obese/overweight children (t =9.735,9.681,26.070,all P ＜ 0.01),whereas no significant differences were found in the concentration of Escherichia,Bifidobacterium and Bacteroides between 2 groups.According to the stratified analysis of ethnicity,gender and age,there was no significant difference among Han,Kazakh and Uyghur children.While stratified by gender,Bifidobactcrium was significantly lower in girls than that of boys (t =4.931,P ＜ 0.05).The distribution of the 6 types of intestinal bacteria genera was no statistically significant among different ethnicity,gender and age groups.Conclusions The intestinal bacteria genera number distribution in different ethnicity,gender and age groups makes no sense.The 16SrRNA type number of the Lactobacillus,Clostridium and Enterococcus may be associated with childhood obesity.
