Gender as a social and structural variable: research perspectives from the National Institutes of Health (NIH).

Gender is a social and structural variable that encompasses multiple domains, each of which influences health: gender identity and expression, gender roles and norms, gendered power relations, and gender equality and equity. As such, gender has far-reaching impacts on health. Additional research is needed to continue delineating and untangling the effects of gender from the effects of sex and other biological variables. The National Institutes of Health (NIH) vision for women's health is a world in which the influence of sex and/or gender are integrated into the health research enterprise. However, much of the NIH-supported research on gender and health has, to date, been limited to a small number of conditions (e.g., HIV, mental health, pregnancy) and locations (e.g., sub-Saharan Africa; India). Opportunities exist to support transdisciplinary knowledge transfer and interdisciplinary knowledge building by advancing health-related social science research that incorporates best practices from disciplines that have well-established methods, theories, and frameworks for examining the health impacts of gender and other social, cultural, and structural variables.
