Objective  To compare the accuracy of body mass index(BMI), waist circumference(WC), waist-hip ratio(WHR), waist-to-height ratio(WHtR), body adiposity index(BAI) and body fat percentage(PBF) in the prediction of Kazakh obesity, and to calculate the value of best cut-off point of six indexes in screening Kazakh obesity.   Methods  The accuracy of BMI, WC, WHR, WHtR, BAI and PBF on the prediction of obesity was compared by chi-square test, linear correlation analysis and receiver operating characteristic (ROC) curve analysis.   Results  The result  of chi-square test showed that the result  of WC and WHtR, BMI and BAI were similar in the prediction of Kazakh obesity. In the linear correlation analysis, WC and BMI had a strong correlation with total fat mass. The result  of ROC curve analysis showed that the WC had the largest area under the curve(AUC), followed by BMI.   Conclusion  The Kazakh people are overweight and obese, and the WC is the most accurate in screening Kazakh people for obesity. It is suggested that BMI,WC and WHtR are used to predict the obesity of Kazakh people.
