Limited research has quantified variation in the characteristics of the breasts among women and determined how these breast characteristics are influenced by age and body mass. The aim of this study was to classify the breasts of women in the community into different categories based on comprehensive and objective measurements of the characteristics of their breasts and torsos, and to determine the effect of age and body mass index on the prevalence of these breast categories. Four breast characteristic clusters were identified (X-Large, Very-ptotic & Splayed; Large, Ptotic & Splayed; Medium & Mildly-ptotic; and Small & Non-ptotic), with age and BMI shown to significantly affect the breast characteristic clusters. These results highlight the difference in breast characteristics exhibited among women and how these clusters are affected by age and BMI. The breast characteristic clusters identified in this study could be used as a basis for future bra designs and sizing systems in order to improve bra fit for women. Practitioner summary: This original research provides evidence for bra designers and manufacturers on the diverse breast characteristics exhibited by women within the population and the significant effect that both body mass index and age have on the breast characteristic clusters. Future bra designs should consider the variation in breast characteristics among women.

针对女性乳房特征差异进行量化研究，并确定这些乳房特征如何受年龄和体重影响的研究较少。本研究旨在基于对女性乳房和躯干特征的全面客观测量，将社区女性的乳房分为不同类别，并确定年龄和体重指数对这些乳房类别的患病率的影响。研究确定了四个乳房特征集群（超大、非常下垂且外扩；大、下垂且外扩；中且轻度下垂；小且不下垂），年龄和体重指数对乳房特征集群有显著影响。这些结果突出了女性乳房特征的差异，以及这些集群如何受年龄和体重指数的影响。本研究中确定的乳房特征集群可作为未来胸罩设计和尺码系统的基础，以改善女性胸罩的贴合度。从业者总结：这项原创研究为胸罩设计师和制造商提供了证据，证明人群中女性乳房特征的多样性，以及体重指数和年龄对乳房特征集群的显著影响。未来的胸罩设计应考虑女性乳房特征的差异。
