Medical Diagnosis Disparities Based on Gender: Facts, Reasons, and Consequences
In the realm of healthcare, gender bias significantly impacts diagnoses and outcomes for patients across different genders. This bias, rooted in historical exclusion of women and gender minorities in medical research, permeates the entire healthcare system, from research to clinical practice.
One of the most concerning effects of gender bias is the delayed diagnoses women often face. Women typically experience longer delays before being diagnosed with serious conditions compared to men, with studies showing delays of 2.5 years for cancer diagnosis and 4.5 years for diabetes [1]. This is largely due to the historical underrepresentation of women in clinical trials and the lack of training among providers on female-specific disease presentation.
Another area where gender bias has a significant impact is in drug safety. From 1977 to 1993, women of childbearing age were largely excluded from FDA-regulated clinical trials, resulting in many medications being initially tested only on men [1]. This has led to women experiencing significantly more adverse drug reactions, with eight out of ten drugs removed from the market between 1997 and 2000 due to side effects primarily affecting women [1].
Gender bias also leads to misdiagnosis and poorer outcomes for certain conditions. Women with conditions like acute myocardial infarction are 50% more likely to be misdiagnosed than men, resulting in higher early mortality and worse long-term survival [3]. Meanwhile, men may experience higher mortality after some conditions, such as hip fracture [3], indicating sex-specific risk profiles.
Transgender and intersex individuals also face challenges due to a lack of understanding of their specific needs by healthcare providers, leading to reported gaps in quality of treatment and support [3]. Similarly, psychiatric and neurodevelopmental co-occurrences in gender-diverse populations (e.g., autism and anxiety with gender dysphoria) require specialized awareness that is often insufficiently addressed [2].
Female surgeons also encounter gender bias in surgical culture, including poorly fitting instruments and assumptions about competence, which can sideline their participation and advancement in clinical practice [5].
Addressing these issues requires integrating sex and gender considerations into research, clinical training, and guidelines to improve health equity for all genders. However, there is a gap in research about how gender bias has affected the diagnosis of COVID-19, as most studies on COVID-19 fail to take sex and gender into account [4].
Moreover, women in medical journals and leadership positions are underrepresented, limiting the influence women can have on medical research and best practices. In the past, many scientific studies excluded female participants or females of childbearing age to eliminate the possibility of female sex hormones influencing the results or to prevent the risk of drugs affecting a potential pregnancy.
Women are nearly as likely as men to have a mental health condition. Risk factors for mental illness that disproportionately affect women include societal pressures, discrimination, and trauma. Gender bias leads to a higher number of mental illness diagnoses and prescriptions for mood-altering drugs for women compared to men, even after controlling for higher rates of mental health conditions in women.
Gender bias refers to a preference for one gender over another, often based on prejudices and stereotypes. A study found that females presenting with a heart attack were more likely to die when a male doctor treated them, compared with a female doctor [2]. Women with chronic pain receive less pain medication, less effective pain medication, more antidepressant prescriptions, and more referrals to mental health services compared to men.
Many countries do not have laws to protect people against gender-based discrimination, leaving women healthcare workers and patients without support when they experience harassment, abuse, or violence.
In summary, addressing gender bias in medical diagnosis and healthcare outcomes requires a concerted effort to incorporate sex and gender considerations into research, clinical training, and guidelines. This will help to improve health equity for all genders, ensuring that everyone receives accurate, timely, and effective healthcare.
