It is unclear whether male and female physician researchers who perform similar work are currently paid equally.
To determine whether salaries differ by gender in a relatively homogeneous cohort of physician researchers and, if so, to determine if these differences are explained by differences in specialization, productivity, or other factors.
A US nationwide postal survey was sent in 2009-2010 to assess the salary and other characteristics of a relatively homogeneous population of physicians. From all 1853 recipients of National Institutes of Health (NIH) K08 and K23 awards in 2000-2003, we contacted the 1729 who were alive and for whom we could identify a mailing address.
The survey achieved a 71% response rate. Eligibility for the present analysis was limited to the 800 physicians who continued to practice at US academic institutions and reported their current annual salary.
A linear regression model of self-reported current annual salary was constructed considering the following characteristics: gender, age, race, marital status, parental status, additional graduate degree, academic rank, leadership position, specialty, institution type, region, institution NIH funding rank, change of institution since K award, K award type, K award funding institute, years since K award, grant funding, publications, work hours, and time spent in research.
The mean salary within our cohort was $167,669 (95% CI, $158,417-$176,922) for women and $200,433 (95% CI, $194,249-$206,617) for men. Male gender was associated with higher salary (+$13,399; P = .001) even after adjustment in the final model for specialty, academic rank, leadership positions, publications, and research time. Peters-Belson analysis (use of coefficients derived from regression model for men applied to women) indicated that the expected mean salary for women, if they retained their other measured characteristics but their gender was male, would be $12,194 higher than observed.
Gender differences in salary exist in this select, homogeneous cohort of mid-career academic physicians, even after adjustment for differences in specialty, institutional characteristics, academic productivity, academic rank, work hours, and other factors.
目前尚不清楚从事类似工作的男女医师研究人员的薪酬是否相同。
确定在相对同质的医师研究人员群体中，薪酬是否因性别而异，如果是，确定这些差异是否由专业化程度、生产力或其他因素解释。
2009-2010 年，我们向美国全国范围内的邮政调查对象发送了一份评估相对同质的医师群体薪酬和其他特征的调查问卷。在 2000-2003 年期间获得美国国立卫生研究院（NIH）K08 和 K23 奖的 1853 名收件人中，我们联系了在世且能够确定邮寄地址的 1729 名收件人。
该调查的回应率为 71%。本分析的入选标准仅限于在美学术机构工作并报告其当前年薪的 800 名医生。
构建了一个线性回归模型，考虑了以下特征：性别、年龄、种族、婚姻状况、父母状况、额外的研究生学位、学术职称、领导职位、专业、机构类型、地区、机构 NIH 资助排名、自 K 奖以来机构的变化、K 奖类型、K 奖资助机构、K 奖以来的年限、资助款、出版物、工作时间和研究时间。
在我们的研究队列中，女性的平均薪酬为 167669 美元（95%CI，158417-176922），男性为 200433 美元（95%CI，194249-206617）。即使在最终模型中对专业、学术职称、领导职位、出版物和研究时间进行了调整，男性性别仍与更高的薪酬相关（+13399 美元；P=0.001）。彼得斯-贝尔森分析（将回归模型中男性的系数应用于女性）表明，如果女性保留其他测量特征，但性别为男性，那么预期的平均薪酬将比观察到的高 12194 美元。
在这个选择的、同质的中年学术医生群体中，性别差异存在于薪酬中，即使在调整了专业化程度、机构特征、学术生产力、学术职称、工作时间和其他因素后也是如此。
