A Report on the Breast Development of Healthy Females of the Right Age in Different Regions

Abstract

Objective: To observe the state of breast development of the healthy females of the right age in different regions. Methods: We randomly chose 1540 of 18 -25 years old unmarried or married healthy females of the right age from both Guangxi and Yunnan provinces separately for regular checkups. Also we took notes on these females' height and chest circumference and other indexes. According to the perfect chest circumference of Chinese females in relation to height, namely this relational expression-Standard Circumference = Height × 0.53, we evaluated the basic state of breast development of females from the two areas and then presented related research conclusions. Results: After the statistical analyses on every index of 1540 cases of healthy females of the right age from the two areas each, we found that the breast development of healthy women of the right age in Yunnan is more perfect than that of Guangxi, and in comparison to every index, there is a remarkable difference, and that is, P < 0.01. Conclusions: The state of breast development of healthy females of the right age is different in different areas. Some breasts are especially big; some are a little bit smaller; some are proper and some are relatively flat; also some breasts are strong while some are pendulous. In a word, there are some differences. These differences exist not only in China but also in every part of the world. The female whose chest circumference tends to be more close to the perfect is more likely to be more confident and more active, and also her life is full of sensibility and charm.
