Obesity has become a major public health issue worldwide. But to date, there is little information about prevalence of obesity in children of ethnic minority in China. Our team carried out a series research to evaluate the epidemiology and risk factors of obesity in children who lived in Xinjiang from 2001 to 2010. A total of 10247 school children of Han, Hui, Uygur and Kazak nationalities aged 6-14 years were selected by a cluster sampling from Xinjiang for anthropometric measurement and demographic survey. Prevalence of obesity was 5.09%, 3.08%, 4.83%, and 8.94% of Han, Hui, Uygur and Kazakh nationalities, respectively. Prevalence of obesity in Kazakh is higher than that of an average national level (8.1%). In order to explore the risk factors relevant with obesity in children including gene level and environmental factor, our team carried out case-control strategy to study all above factors in Han, Hui, Uygur and Kazakh nationalities. We genotyped putative causative genes that may be involved in obesity including ApoE, FTO, β 3AR, leptin gene polymorphism and assessed the association those genes with obesity. The frequency of the above genotypes was significantly different in Han, Hui, Uygur and Kazakh nationalities. To explore the influence of intestinal flora on obesity, real-time fluorescence quantitative PCR was used in Kazakh children. An association between reduced gut Bacteroidetes and Bact/Firm ratio with obesity in female Kazakh children was identified. Further studies are necessary to elucidate the mechanism behind these changes as well as the value of determining their presence for predicting obesity.
