摘　　要：对西安市1259名6～18岁女学生乳晕发育进行了调查。测量了乳晕横径和垂直径,建议采用“乳晕单位”(aroolar unit)表示发育程度。结果提示:乳晕单位快速增长期在8～14岁。增长峰值年龄为11.97岁。8岁前、14岁后增长缓慢。乳晕发育和乳房发育密切相关,各级乳房发育时乳晕单位均达到一定水平。乳晕单位达“临界值”(7.00cm^2)时,83％女子初潮发生。乳晕单位同身高、体重、胸围有非常显著的正相关(P<0.001),和胸围的相关最为密切(r=0.728)。The investigation on areolar development in 1259 girls aged 6～18 years in Xian was made. Areolar diameters, including cross and erect dia- meters, were measured, We suggest that 'areolar unit' may show developing degrees. The results have shown that the increase in areolar unit is fast- er in the period of 8～14 yearsold, ard the increase in areolar unit peaks in 11.97 years old. The iner- ease is slower before 8 yearsold and after 14 years old. The development of areola is close correla ted with breast development stages, and at each stage of breast development areolar unit consiste- ntly reaches corresponding level. When areolar unit reached its critical value(7.00cm^2), menarche appeared in 83.2% of girls. There are very signi- ficantly positive correlations between areolar unit with body high, body weight and chest circle (P<0.001). Areolar unit and chest circle are the most close correlation (r=0.728).
