Purpose: The association between body mass index (BMI) and Breast Imaging Reporting and Data System (BIRADS) category 3 and 4 findings has not been fully explored. Methods: We used breast ultrasonography to diagnose BIRADS 3 and 4 findings. BMI was calculated as the weight divided by the square of the height (kg/m2). Multivariable logistic regression was employed to assess the association between BMI and BIRADS 3 and 4. Results: Higher BMI was significantly associated with lower risk of BIRADS 3 and 4 findings [adjusted odds ratio (AOR) = 0.51, 95% confidence interval (CI) =0.37-0.70]. The association between lower BMI and BIRADS 3 and 4 findings was observed mainly in women before the age of 50 (AOR = 0.50, 95% CI = 0.34-0.74). Conclusion: Lower BMI was associated with BIRADS 3 and 4 breast findings in Asian women, and age modifies this association.

目的：身體質量指數與乳房成像報告和數據系統分類三和四之間的關聯性並未被充分研究。方法：本研究使用乳房超音波來診斷乳房成像報告和數據系統分類三和四。身體質量指數計算為體重除以身體的平方（公斤／米平方）。使用多變量邏輯式迴歸來探討身體質量指數和乳房成像報告和數據系統分類三和四關聯性。結果：偏高的身體質量指數有較低的乳房成像報告和數據系統分類三和四發現。而較低的身體質量指數和乳房成像報告和數據系統分類三和四發現之關聯性主要在婦女年紀小於50歲的族群。結論：在亞洲女性，偏低的身體質量指數和乳房成像報告和數據系統分類三和四發現有關聯性，而年紀會影響此一結果。
