Gender and health is a multidisciplinary field that examines how gender identity, gender roles, and sex-based biological differences shape health outcomes, access to healthcare, and the experience of illness across populations. While sex refers to biological attributes such as chromosomes, hormones, and reproductive anatomy, gender encompasses the socially constructed roles, behaviors, and expectations associated with being male, female, or nonbinary. Both dimensions interact in complex ways to influence disease prevalence, symptom presentation, diagnosis, treatment efficacy, and mortality. For example, cardiovascular disease has historically been studied predominantly in male subjects, leading to diagnostic criteria that often miss atypical presentations more common in women, contributing to higher fatality rates among women who experience heart attacks.
Gender-based disparities in health extend well beyond biology. Social determinants such as income inequality, educational access, occupational hazards, exposure to violence, and caregiving burdens are deeply gendered and profoundly affect physical and mental well-being. Women and gender minorities frequently face barriers to healthcare including provider bias, lack of research representation, stigma, and inadequate insurance coverage for gender-specific needs. Men, on the other hand, are less likely to seek preventive care and mental health treatment due to societal expectations around masculinity, contributing to higher rates of substance abuse, suicide, and undiagnosed chronic conditions. Transgender and gender-diverse individuals encounter additional obstacles, including discrimination in clinical settings and limited access to gender-affirming care.
Addressing gender disparities in health requires systemic changes across research, clinical practice, and policy. Gender-responsive health systems integrate sex-disaggregated data collection, gender-sensitive clinical training, inclusive research design, and equitable resource allocation. International frameworks such as the World Health Organization's gender mainstreaming strategy and the United Nations Sustainable Development Goals explicitly recognize gender equity as foundational to global health improvement. By understanding how gender operates as both a social determinant and a structural force in healthcare, practitioners and policymakers can design interventions that reduce inequities, improve outcomes for all genders, and build more just health systems.
