Objective  To explore the relationship between obesity indexes and body fat rate in Naxi adults.   Methods  A total of 687 Naxi adults aged between 18 and 90 were selected from Yulong County, Lijiang City, Yunnan Province. Body weight, height, chest circumference, waist circumference, hip circumference, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, anterior superior spine skinfold, body mass index（BMI）,visceral fat index and body fat percentage were measured by anthropometry and bioelectrical impedance analysis. And the indexes and body fat percentage were statistically analyzed.   Results  The average body fat percentage of Naxi men was normal, while the women was obese. According to the criteria of visceral fat index, the average visceral fat index of Naxi men and women was within the normal range. According to the waist circumference, the waist circumference of Naxi men was within the normal range, while the waist circumference of women belonged to abdominal obesity. Correlation analysis showed that body weight, chest circumference, waist circumference, hip circumference, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, anterior superior iliac spine skinfold, BMI, visceral fat index were positively correlated with body fat percentage among Naxi adults. There was the strongest correlation between visceral fat index and body fat percentage in Naxi men, followed by BMI; Naxi women’s chest circumference and body fat percentage, followed by waist circumference.   Conclusion  All the obesity indexes of Naxi adults are positively correlated with body fat percentage, and there are gender, regional and ethnic differences in the degree of correlation.
