Objective To study the changes of circumference value of Jiangxi urban Han with age. Methods Based on the measurement of the circumferences of 307 urban adults (151 males,156 females) of Jiangxi Han nationality (including the circumference of head, neck, chest, chest circumference at inspiration, chest circumference at expiration, abdomen, hip, thigh, calf, upper arm, fore-arm and maximum biceps), the study analyzed the changes of circumference value with age, and with cluster analysis, compared the circumference values between Jiangxi Han nationality and other 18 nationalities in China. Results The results of variance analysis showed that males and females had significant differences among age groups in chest, chest circumference at inspiration, chest circumference at expiration, abdomen, thigh,calf, upper arm and maximum biceps. In addition, the forearm circumference of female existed significant differences among age groups. Correlation analysis revealed that male’s abdominal circumference was positively associated with age, while calf circumference, arm circumference and maximum biceps circumference were negatively correlated with age. Female’s chest, chest circumference at inspiration, abdominal circumference and upper arm were positively correlated with age. The rest of circumference had no significant sexual difference in the circumference of abdomen, thigh, hip and thigh. The remaining of 9 circumference values were statistically significant in gender, and male’s ones were significantly higher than those of females. Conclusion The circumference value of Jiangxi urban Han has the characteristics of the North type.
