Breast hypertrophy causes physical and psychological symptoms. Reduction mammaplasty is a surgical procedure to lessen discomfort. However, there is a dispute about whether the weight of breast resection is related to body weight. This study aims to provide Chinese data and assess the association between body weight and removed weight in women undergoing reduction mammaplasty.
Retrospective data were collected from 1777 breasts in a single center in 17 years. Simple linear regression analysis was performed to establish whether removed weight and removed weight ratio (removed weight/body weight) correlated with the body weight. The correlations were then analyzed again after grouping according to the removed weight.
For all breasts included, removed weight or ratio positively correlates with body weight. When the removed weight is more than 1000g, there is no statistically significant correlation between body weight and removed breast weight. When removed per breast weight is more than 600g, there is no correlation between body weight and removed breast weight ratio.
The correlation between body weight and removed weight or ratio decreased with increasing removed weight. When removed weight >600g, the degree of breast hypertrophy is not related to body shape.

乳房肥大会引起身体和心理症状。乳房缩小成形术是一种减轻不适的外科手术。然而，关于乳房切除重量是否与体重相关存在争议。本研究旨在提供中国的数据，并评估接受乳房缩小成形术的女性体重与切除重量之间的关联。
回顾性收集17年间来自单一中心的1777例乳房的数据。进行简单线性回归分析，以确定切除重量和切除重量比（切除重量/体重）是否与体重相关。然后在根据切除重量分组后再次分析相关性。
对于纳入的所有乳房，切除重量或切除重量比与体重呈正相关。当切除重量超过1000g时，体重与切除乳房重量之间无统计学显著相关性。当每侧乳房切除重量超过600g时，体重与切除乳房重量比之间无相关性。
体重与切除重量或切除重量比之间的相关性随着切除重量的增加而降低。当切除重量>600g时，乳房肥大程度与体型无关。
