Background: Across the life course, women and girls with learning disabilities and their carers report difficulties in accessing information and support with menstruation, yet their experiences are often overlooked in initiatives to improve menstrual health and wellbeing. Our aim was to collaborate with women with learning disabilities to co-produce future research priorities in a UK context. Methods: We undertook a two-part scoping exercise to explore what is known about this topic from a life course perspective, beginning pre-menarche and extending to post-menopause support. This combined a rapid scoping review of the literature since 1980 with a stakeholder consultation where people with learning disabilities, family carers, advocacy groups and staff working across education, health and social care were invited to share their experiences of menstruation support. Findings: UK and international literature provided insight across five narrative themes. Seventy stakeholders took part in our consultation, enabling the identification of five key themes. Findings across both highlight examples of supportive practice and valued resources alongside enduring health inequalities and barriers to menstruation support faced by women and girls with learning disabilities across the life course. Conclusion: Our scoping exercise identified multiple gaps in research and practice, ongoing reproductive health inequalities and a need for improved access to peer support, resources and training that take a life course approach. The scoping exercise indicates the need for further empirical research on menstruation and learning disability, with a particular focus on collating people's lived experiences.
