Sex and gender in medical education: a national student survey
© The Author(s). 2016
Published: 14 October 2016
Gender- and sex-specific medicine is defined as the practice of medicine based on the understanding that biology (dictated by sex chromosomes) and social roles (gender) are important in and have implications for prevention, screening, diagnosis, and treatment in men and women. In light of the many ways that sex and gender influence disease presentation and patient management, there have been various initiatives to improve the integration of these topics into medical education curriculum. Although certain schools may include the topics, their impact on the student body’s knowledge has not been as fully studied. By studying the opinions of US allopathic and osteopathic-enrolled students on the extent to which their schools address these topics and their understanding of these topics, this study examined the role of gender specific medicine in the US medical school curriculum.
An email solicitation with link to an anonymous survey was sent to approximately 35,876 student members of five US medical student organizations. The survey instrument consisted of yes/no, multiple choice, and attitude awareness questions. Data was analyzed as a complete data set to evaluate national trends and via subset analysis using chi-square, paired t test, and one-way anova.
A total of 1097 students responded. The majority of respondents strongly agreed that sex and gender medicine (SGBM) improves patient management (96.0 %) and should be included as a part of the medical school curriculum (94.4 %). Only 2.4 % of participants agreed that SGBM is the same as Women’s Health. When asked specifically about inclusion of an identified sex and gender-based medicine curriculum at their institution, students answered not sure at 40.8, 25.1, 19.1, and 20.3 % from first year to fourth year, respectively. Males reported a higher rate of exposure to SGBM content areas (in medical history taking, domestic violence) than women.
Medical students recognize the differentiation between SGBM principles and women’s health, and understand the translational value of sex and gender-specific principles in the clinical setting. However, current curricular offerings fall short of providing students with adequate coverage of specific evidence-based health differences.
Beginning in the 1960s, as disparities in women’s rights came to the fore-front, the medical field began to develop an increased interest in women’s health . In a traditional sense, the field of women’s health focused on those topics related to pregnancy and reproduction almost exclusively. However, following the publication of the Institute of Medicine’s report, Does Sex Matter , in 2001 and the publication of Principles of Gender-Specific Medicine in 2004, an increasing emphasis was placed on the importance of sex and gender medicine .
While sex is defined as the unique physical makeup of men and women due to chromosomal, reproductive, and hormonal differences, gender focuses on the implications of society’s psychosocial framework relating to the norms of being a man versus a woman . Therefore, sex and gender medicine is defined as understanding that biology and social roles are important in and have implications for prevention, screening, diagnosis, and treatment .
Because sex and gender play a significant role in the medical management of patients, it is paramount that these topics be incorporated into medical research and education. These differences in physiology and pathophysiology between males and females are evident in many disease processes, diagnostic tests, and treatment options. In a recent review of scientific literature, over 3000 articles dealing with sex and gender differences in disease presentation were found . For instance, it is widely accepted that cardiovascular disease (CVD) presents differently in men and women, and that the knowledge of such differences is a critical component of the clinical armamentarium . In addition to disease presentation, sex and gender influence treatment efficacy. At the most fundamental level, one’s sex and gender will affect pharmacokinetics and pharmacodynamics. For example, in the case of the sleep aid, zolpidem, women have a much lower metabolism rate resulting in higher plasma concentrations and sensitivity . Thus, at equal doses, zolpidem causes longer periods of impairment in women. In February 2014, zolpidem became the first drug to have different US Food and Drug Administration (FDA) guidelines for dosing in men versus women .
Acknowledging that sex and gender have medical implications has led to various initiatives to improve the integration of these topics into the medical education curricula. In 1994 and 1995, the Association of American Medical Colleges (AAMC), in response to a Congressional request, surveyed the inclusion of women’s health and sex and gender medicine in approximately 100 medical schools [9, 10]. Following the AAMC surveys, four additional studies between 1997 and 2002 were conducted to track curricular progress in incorporating this topic. These studies identify a lack of comprehensive integration of sex and gender medicine into the basic sciences and clinical education [11, 12].
In 2011, A Sex and Gender Based Medicine Faculty Survey was administered to faculty from the majority of medical schools in the USA and Canada. Of the 44 schools that responded, 70 % indicated that they did not have a formal sex- and gender-specific integrated medical curriculum. When asked if adequate coverage was granted to ten specific health topics in which sex- and gender-based evidence exists, 45–70 % ranked their coverage as minimal .
National student survey
Based on these previous studies, it is apparent that medical education in the USA has not adequately integrated sex and gender-based medicine into its curricula. Thus, the purpose of this study was to determine, from the perspective of medical students, how effectively medical schools integrate evidence-based sex and gender differences into curricula, as well as these students’ knowledge, attitudes and awareness of sex and gender medicine. This study represents the first national survey of medical students’ knowledge, attitudes, and awareness of sex and gender.
A convenience sample of male and female US medical student members of the following national medical student organizations: American Medical Student Association, the American Medical Women’s Association, the Asian Pacific American Medical Student Association, the Latino Medical Student Association, and the Student National Medical Association was studied. Inclusion criteria were students who attended 4-year MD or DO medical schools where either all 4-year or the last two clinical years were completed on campuses located in the USA. Students from international medical schools and naturopathic medical schools were excluded.
A total of approximately 35,876 medical student members of the organizations received the solicitation email and 1097 responded. The estimated total membership of the organizations is likely a duplicate count as cross membership with other organizations is possible. However, the achieved sample size (1097) ensures a 99 % confidence level with 4 % margin of error.
Women’s Health: Screening, diagnosis and management of conditions unique to female anatomy, more prevalent in women, and/or more consequential in women
Men’s Health: Screening, diagnosis and management of conditions unique to male anatomy, more prevalent in men, and/or more consequential in men
Sex and Gender-Specific Medicine: The practice of medicine based on the understanding that biology (dictated by sex chromosomes) and social roles (gender) are important in and have implications for prevention, screening, diagnosis, and treatment; and in the design and implementation of health research, policy, programs and services in men and women.
Demographic data s included: student’s age, school type, program, year in school, and field of study prior to medical school. The attitude and awareness component used a five-point Likert Scale to assess perceptions of sex and gender medicine’s importance and respondent’s familiarity with the topic (1 = strongly disagree; 2 = disagree; 3 = neither agree nor disagree; 4 = agree; 5 = strongly agree). Within the women’s health, men’s health and gender-specific medicine sections, respondents were asked to indicate whether their institution included specific curricular offerings such as required reading, objective structured clinical exams (OSCEs), fellowships or residency programs in these respective areas. The survey included these questions regarding institutions’ educational resources and training programs in women’s health, men’s health, and sex- and gender-specific health to better assess integration of these areas.
In the content areas subsection, students indicated the extent to which their institution covered sex and gender differences in major content areas such as pulmonology and endocrinology via a four-point Likert scale (1 = no course or lectures, 2 = minimal coverage, 3 = moderate coverage, 4 = extensive coverage) that included definitions for minimal, moderate and extensive coverage. The specific curricular items subsection included yes/no questions regarding whether the student’s medical education to date included curricular opportunities pertaining to certain evidence-based health differences between men and women. The content areas were chosen as having level one or two evidence for the differences described. Although free-text entry was included in the survey, the responses and comments were not analyzed in this manuscript. Qualtrics survey software was used to build and administer the survey and all data were automatically de-identified through the software; questions in the demographics subsection did not include any identifying information. Because the email solicitation was sent to student members at different levels in their medical education, survey logic was incorporated to ensure that questions remained relevant to the student based upon their current education and experience. For example, only third and fourth year students were shown questions regarding specific institutional offerings (Question 6a, 7a) as a majority of medical school program introduce electives during those years (Additional file 1). The initial survey was created by a group of faculty and students at Texas Tech University Health Sciences Center. For the purposes of this work, extensive revisions were incorporated by the authors, medical students at Albany Medical College, and a survey design and statistical analyst from Belmont University. Once drafted, the survey was beta tested by seventeen students from Texas Tech Health Science Center and Albany Medical College in addition to national sex and gender medicine faculty experts from the Sex and Gender Women’s Health Collaborative (http://sgwhc.org/).
The Gender-Specific and Men’s and Women’s Health Curriculum National Survey was conducted under an IRB-approved protocol through Texas Tech University Health Sciences Center, and all participants were informed in the email solicitation that, by completing the de-identified survey, they were voluntarily consenting to participate in a research study. Participants were recruited through third-party distribution of an IRB approved email specifically concerning the survey. Student members of the five participating medical student organizations were contacted by their respective organization. As part of their membership, students of these organizations had previously agreed to be contacted for various purposes including surveys. No compensation or incentive was offered to study subjects and participation was strictly voluntary. The email solicitation described the intent of the study and included the link to the electronic survey. The survey required approximately 10–15 min to complete. The link was active for 110 days, and a reminder email was sent out by the organizations before the link expired.
Data from the de-identified survey responses were analyzed both as a complete data set to evaluate national trends and via subset analysis according to demographic data collected. Gender differences between mean responses to Likert scale questions were analyzed by conducting independent samples t tests, and mean differences by year-in-school were analyzed by performing one-way ANOVAs and means for homogenous subsets were further explored and validated through the use of Tukey post hoc tests. ANOVA analysis was also performed to compare exposure to sex and gender differences between different class years. For Likert scale questions, care was taken to set any non-responses of “don’t know” or “not sure” to system missing before generating or testing means.
Binary data collected in response to yes/no questions and other nominal data collected through yes/no questions with additional response options were analyzed through the use of Pearson’s chi-square tests. Subsequent to the analysis of mean differences, for the purpose of reporting respondents’ attitudes and perceptions in clearer fashion, questions were collapsed into categories of agree (containing response of “strongly agree” and “agree”), and disagree (“strongly agree” and “disagree”). In order to address gender bias in response rate, weighted responses were calculated based on data from the American Association of Medical Colleges’ total enrollment records from 2015–2016 divided by sex.

Of all respondents, 25.4 % were in their first year of medical school, 33.7 % in their second year, 21.5 % in their third year, 17.6 % in their fourth year, and 1.8 % were in their fifth year or more. The majority (88.1 %) of respondents were between the ages of 21 and 30. A significant portion of the respondents reported the biological sciences to be their prior field of study in undergraduate (69.0 %). In terms of gender distribution, 74.3 % of respondents were women and 25.2 % were men (Table 1).

ANOVA (p value)
One-way ANOVA tests revealed that class years differed significantly in their attitudes and perceptions of sex and gender medicine (Table 2). In particular, differences were observed between first and, to a lesser degree, second year students and students in their third and fourth years. Perceived exposure with the topic of sex and gender medicine grew significantly as class year progressed, and the perception that sex and gender medicine is the same as women’s health decreased. However, opinions on whether knowing sex and gender differences improves ability to manage patients remained at 94 % or greater across the four years (first year: 97.8 %; second year: 96.2 %; third year: 94.0 %; fourth year 95.3 %) (Table 2).
Sex- and gender-based medicine curricular offerings
Despite the fact that more than half of respondents reported to be familiar with the topic, when asked about the inclusion of an identified sex and gender-based curriculum in their medical education, only 31.1 % of students responded yes (42.0 % responded no, and 26.9 % were unsure; n = 1096). When asked if the curriculum included specific classes or programs on sex and gender differences, 31.6 % of respondents chose no, and 48.1 % of respondents chose yes. Only 43.1 % of students report that their curriculum has given them a better understanding of sex and gender medicine, and only 34.5 % report they would feel prepared to manage sex and gender difference in healthcare.
Classes responded differently to whether their curricula have provided a better understanding of sex and gender medicine as well as whether their curricula included the teaching of sex and gender differences. Specifically, second year and fourth year students were more likely than first and third year students to report their curricula included sex and gender education (first year = 31.0 %; second year = 54.2 %; third year = 50.6 %; fourth year = 57.8 %) and agree that their curricula has given them a better understanding of sex and gender medicine (first year = 28.7 %; second year = 48.9 %; third year = 43.8 %; fourth year = 50.3 %).
Students were asked to report the extent of coverage of sex- and gender-based medicine topics within ten broad fields of medical study where noted sex and gender differences exist: domestic violence, substance abuse, mental health, nutrition, pharmacology, pulmonology, cardiology, rheumatology, infectious disease, and endocrinology. Moderate to extensive coverage was reported for endocrinology (76.4 %), medical history taking (72.5 %), mental health (66.2 %), rheumatology (64.1 %) and cardiology (64.0 %), infectious disease (59.4 %), pharmacology (59.1 %), substance abuse (57.0 %), domestic violence (56.3 %), pulmonology (54.7 %), and nutrition (45.2 %).
Sex- and gender-based medicine offerings versus knowledge
Students were also asked whether select examples of specific evidence-based health differences between men and women—(a) presenting symptoms of myocardial infarction (MI), (b) outcomes after low impact fractures (c) dosing of zolpidem, and (d) narcotic addiction—had been included in their medical education to date. The selected examples were included because significant differences in outcomes for males and females are well-documented in research over the past decade, yet is unknown if this evidence has been incorporated into training.

Chi-square (p value)
Results suggest that a majority of US medical students are familiar with the topic of sex and gender medicine as a separate entity from women’s and men’s health, and believe this topic will improve their abilities to treat patients in the future. However, when asked if they feel as though their curriculum has prepared them to manage these differences at a clinical level, less than half of students agreed. When asked specifically about inclusion of an identified sex and gender-based medicine curriculum at their institution (question 8a), students answered not sure at 40.8, 25.1, 19.1, and 20.3 % from first year to fourth year, respectively. It is important to note that students answered “no” to the same statement (question 8a) at rates of 35.7, 40.1, 49.8, and 42.3 % from first year to fourth year, respectively. Given that upper level students have had a broader exposure to the institution’s entire curriculum, this suggests a gap in existing medical school curricula with respects to sex- and gender-based exposure and that a basic review of the definitions of sex and gender is merited.

The initiative to embed sex and gender education into medical training has begun to take hold at the graduate level in fields such as emergency medicine . Resident electives and fellowships in sex- and gender-based medicine are established as a way to better serve the patients seen in the emergency room . These electives and fellowships at the graduate training level validate a direct impact on patient care. In addition to introducing concepts of sex and gender medicine during residency and fellowship, its incorporation throughout medical education will allow all students to gain proficiency in the topic and develop a unique framework from the onset of the student’s clinical years.
While there is evidence that respondents can be more detailed in their responses in a shorter period of time when taking a survey online, there are known logistic difficulties associated with online surveys. These include the potential for the link to reach non-US medical schools through forwarding, excluding potential participants due to incorrect email addresses within a group’s lists, or self-selecting by forwarding through networks of students who have already volunteered to take the survey, which limits how random and representative the surveyed sample is. Online surveys are particularly prone to lower response rates, as was seen in this study’s response rate as well; however, those who complete the survey did so voluntarily, which is better for the quality of the responses. Research has also shown there can be differences in response rates between genders, as seen with a predominantly female response to this study. While it is common for women to respond to survey questionnaires in higher numbers than males, this is a limitation that needs to be acknowledged when extrapolating the results to the medical student population as a whole . Using expected responses from males and females (based on enrollment figures for 2015–2016 from the American Association of Medical Colleges: 48 % female and 53.2 % male)  and the observed rates of 74.3 % female and 25.2 % male in our dataset, weighted values were produced. Responses form the attitudes and perceptions categories fell slightly in agreement; however, responses on exposures to sex and gender topics increased overall.
This study was limited by a binary (male and female) representation of gender. It is important in the future to study the health outcomes seen in the transgender population and evaluate ways in which gender health across the continuum can be better addressed in curriculum.
Based on results of this survey, the next step is to delineate effective integration of SGBM knowledge into mainstream medical education curriculum. Sex and gender influences can be found across the entire health spectrum from birth to death, therefore, threading concepts of sex and gender across the student’s 4-year learning experience through the integration of evidence-based sex and gender knowledge. This approach might avoid the large financial outlays and stagnation that can occur with stand-alone curricula and avoid requests for large blocks of curriculum time and resources which require resources to be subtracted from other curricular areas. Many would agree that finding time for new content in today’s packed curriculum is challenging and viewed less favorably by curriculum leaders. Thus, the threading concept could help engage faculty to participate in the process of sex and gender curriculum integration and garner buy-in from curriculum gate keepers .
Along with identifying faculty leaders who will lead integration of evidenced-based sex and/or gender differences, it is important to delineate core competencies in sex and gender medicine . These objectives and competencies can be presented to students through integrative techniques. A curriculum mapping approach can link areas of SGBM knowledge from didactic studies to clinical competencies that are weaved throughout existing curriculum.
The inconsistency of reported exposure to certain sex- and gender-specific content areas throughout medical school curriculum from year one to year four indicates a need for more cohesive integration of gender-specific principles . Faculty development and support from an “Institutional Leader” is crucial to systematically incorporate SGBM principles into medical content areas from first year to fourth year. Lastly, it is imperative to utilize the “Student Champion(s)” member of the change team to not only engage learners but create the future generation of SGBM institutional leaders.
This survey not only identified knowledge gaps, but also highlighted the dramatic awareness of students in regards to sex and gender differences and their desire to know more. Integration across UME is the goal and will require not only curricular transformation but an inherent culture change from the current assumption that not knowing the difference means there is no difference. Linking the concepts of sex and gender medicine to precision or individualized medicine may help students and institutions further clarify the relevance of such principles. We must assist current health professionals in recognizing the increasing body of knowledge around sex and gender differences, and even more so, passing this knowledge to future providers. The results of this unique and landmark survey should encourage ongoing commitment of US medical school leadership, professional organizations, learners, accrediting bodies, and other stakeholders to close the sex and gender medicine gap in our current curricula.
