Specialty, work effort, and gender have been shown to be associated with physicians' annual incomes; however, careful examination of the association between provider gender and physician incomes after correcting for other factors likely to influence income has not been conducted at the subspecialty level. We sought to determine the association between provider gender and diagnostic radiologists' annual incomes after controlling for work effort, provider characteristics, and practice characteristics.
Using survey responses that were collected throughout the 1990s from 491 actively practicing white diagnostic radiologists, we generated a linear regression model to determine the association between provider gender and radiologists' annual incomes after controlling for work effort, provider characteristics, and practice characteristics.
White female radiologists reported working 2% fewer annual hours than their white male counterparts. Female radiologists had practiced medicine for fewer years than males, were more likely to be employees, as opposed to having an ownership interest in the practice, and were equally likely to be board certified. After adjustment for work effort, provider characteristics, and practice characteristics, female radiologists' mean annual income was $273,907, or $80,090 (23%) lower than that for white males (95% CI: $113,930 lower to $46,250 lower, P < .001).
During the 1990s, female gender was associated with lower annual incomes among diagnostic radiologists. Researchers should further explore the relationship between physician gender and incomes to determine what factors might cause the differences that we found.
专业、工作投入程度和性别已被证明与医生的年收入相关；然而，在亚专业层面，尚未对校正可能影响收入的其他因素后医疗服务提供者性别与医生收入之间的关联进行仔细研究。我们试图在控制工作投入程度、医疗服务提供者特征和执业特征后，确定医疗服务提供者性别与诊断放射科医生年收入之间的关联。
利用20世纪90年代从491名积极执业的白人诊断放射科医生收集的调查回复，我们建立了一个线性回归模型，以确定在控制工作投入程度、医疗服务提供者特征和执业特征后，医疗服务提供者性别与放射科医生年收入之间的关联。
白人女性放射科医生报告的年工作时长比白人男性同行少2%。女性放射科医生的行医年限比男性短，更有可能是雇员，而非拥有执业所有权，并且获得委员会认证的可能性相同。在对工作投入程度、医疗服务提供者特征和执业特征进行调整后，女性放射科医生的平均年收入为273,907美元，比白人男性低80,090美元（23%）（95%置信区间：低113,930美元至低46,250美元，P <.001）。
在20世纪90年代，女性性别与诊断放射科医生较低的年收入相关。研究人员应进一步探索医生性别与收入之间的关系，以确定哪些因素可能导致我们发现的差异。
