To determine the association between race, gender, and pediatricians' annual incomes after controlling for work effort, provider characteristics, and practice characteristics.
We conducted a retrospective analysis of 1172 actively practicing black and white male and female pediatricians who responded to the American Medical Association's annual survey of physicians between 1992 and 2001. We used linear regression modeling to calculate annual incomes adjusted for work effort, provider characteristics, and practice characteristics.
White men reported annual incomes of $183,430. After adjusting incomes for work effort, provider characteristics, and practice characteristics, black male pediatricians' mean annual income was $175,640 (95 per cent confidence interval [95 per cent CI], $150,344-201,138). This was $7790 (4.2 per cent) lower, but not statistically different from that of white men (P = .5). However, compared with white male pediatricians' incomes, white female pediatricians' incomes were $150,636 (95 per cent CI, $140,975-$160,298), or $32,794 (18 per cent) lower (P < .001); and black female pediatricians' incomes were $133,018 (95 per cent CI, $108,736-$157,300), or $50,412 (27 per cent) lower (P < .001).
During the 1990s, female gender was associated with lower annual incomes among pediatricians; differences were greatest for black women. These findings warrant further exploration to determine what factors might cause the gender-based income differences that we found.
在控制工作努力程度、医疗服务提供者特征及执业特征后,确定种族、性别与儿科医生年收入之间的关联。
我们对1992年至2001年间回应美国医学协会年度医生调查的1172名在职的黑人及白人男女儿科医生进行了回顾性分析。我们使用线性回归模型来计算经工作努力程度、医疗服务提供者特征及执业特征调整后的年收入。
白人男性报告的年收入为183,430美元。在对工作努力程度、医疗服务提供者特征及执业特征进行收入调整后,黑人男性儿科医生的平均年收入为175,640美元(95%置信区间[95%CI],150,344 - 201,138美元)。这比白人男性低7790美元(4.2%),但在统计学上无显著差异(P = 0.5)。然而,与白人男性儿科医生的收入相比,白人女性儿科医生的收入为150,636美元(95%CI,140,975 - 160,298美元),低32,794美元(18%)(P < 0.001);黑人女性儿科医生的收入为133,018美元(95%CI,108,736 - 157,300美元),低50,412美元(27%)(P < 0.001)。
在20世纪90年代,女性性别与儿科医生较低的年收入相关;黑人女性的差异最大。这些发现值得进一步探究,以确定可能导致我们所发现的基于性别的收入差异的因素。
