Question to the Department of Health and Social Care:

To ask His Majesty's Government what steps they are taking to address (1) the under-representation of women in health data, and (2) the lack of female-only UK clinical trials.

The Department is committed to ensuring that women are represented across all forms of health data, including National Health Service patient data and data that is used for research. The Department funds research through the National Institute for Health and Care Research (NIHR) and recognises that increasing the diversity of people taking part in research is key to ensuring the evidence and data generated by research is relevant for the whole population.

On 10 March 2025, the NIHR launched its sex and gender policy, which is expected to come into force later in 2025. A document containing the NIHR’s sex and gender policy is attached. This outlines an NIHR statement of intent on integrating sex and gender into health and care research. Implementing such a policy will ensure research accounts for sex and gender across every stage of the research cycle, thus facilitating funding into topics that impact males and females and, crucially, a greater understanding of how males and females might be impacted differently by the same health condition.

The Department and NHS England fund the Research Engagement Network Development Programme, which aims to increase diversity in research participation through the development of research engagement networks with communities who are often underserved by research, and by ensuring diversity in research is considered by integrated care systems.
