绍兴地区汉族成人围度值年龄变化及城乡的比较

Age variation of circumference values and its comparison of urban and rural adults of Shaoxing Han nationality

目的：研究绍兴地区汉族成人围度值的年龄变化特点及城乡间的差异.方法：采用随机抽样方法,测量浙江297例（男性为144例,女性为153例）汉族成人的头围、颈围、胸围、吸气胸围、呼气胸围、腹围、臀围、大腿围、小腿围、上臂围、前臂围、上臂最大围12项指标,采用相关分析和方差分析探讨不同年龄组围度值的变化规律,对城乡间围度值进行了u检验；采用聚类分析方法,对国内21个族群进行了比较.结果：绍兴地区汉族颈部、躯干部围度值均随年龄增长而出现线性增大.城市男性、城市女性与乡村女性上肢围度值亦随年龄增长而出现线性增大,小腿围值则无明显变化.乡村男性上肢围度值与年龄无直线相关,小腿围值随年龄增长而减小.男性年龄组间围度值的差异主要表现在20～岁组与其他年龄组间,城市女性围度值年龄组间的差异主要表现在20～岁组、30～岁组与其他年龄组间；乡村女性围度值的差异表现在多数年龄组间.男性、女性身体围度值城乡间差异多无统计学意义,尤其是女性12项围度值更为接近.各项围度值更接近于中国北方族群,城乡汉族距离最为接近.结论：绍兴地区汉族多数围度值随年龄增长而增大,城乡间多无差异,围度值更接近于中国北方族群.

Objective.. To study age variation of circumference values and its difference of urban and rural adults of Shaoxing Han in Zhejiang province. Methods： A random sampling method was used to measure the circumference values of 297 adults （144 males, 153 females） including the 12 circumference values of the head, neck, chest, inspiratory chest circumference values, expiratory chest circumference values, and the circumference values of the abdomen, hip, thigh, calf, biceps, fore- arm and maximum biceps. The correlation analysis and variance analysis was performed to investigate the variation of the circumference values of different age groups, around circumference values of u-test; cluster analysis method was used to compare among 21 groups. Results： The neck and trunk circumference values had a significantly linear increase with age increasing, so did the upper limbs circumference values of urban males, urban females and rural females; while the calf circumference values did not change significantly. The upper limb circumference values of rural males had no linear correlation with age, and calf circumference values were decreased with age increasing. The circumference values of males in the 20-year group were significantly different from those of the other age groups; the circumference values of urban females in 20-, 30 Year groups were significantly different from those of the other age groups; and the circumference values of rural females were different from those in the other age groups. The difference in the circumference values of males and females were not statistically significant between urban and rural. Especially, the 12 circumference values of female were close. In addition, the circumference values of Shaoxing Han were close to those of the Northern Chinese population. And it is closest between urban and rural of Han. Conclusion： Majority circumference values of Shaoxing Han are increasing with age increasing, with no significant difference between urban and rural, which were close to those of the Northern Chinese populatioru
