Global migration has steadily risen, with 16% of the UK population born abroad. Migrants (defined here as foreign-born individuals) face unique health risks, including potential higher rates and delays in diagnosis of infectious and non-communicable diseases, compounded by significant barriers to healthcare. UK Public Health guidelines recommend screening at-risk migrants, but primary care often faces significant challenges in achieving this, exacerbating health disparities. The Health Catch-UP! tool was developed as a novel digital, multidisease screening and catch-up vaccination solution to support primary care to identify at-risk adult migrants and offer individualised care. The tool has been shown to be acceptable and feasible and to increase migrant health screening in previous studies, but to facilitate use in routine care requires the development of an implementation package. This protocol describes the development and optimisation of an implementation package for Health Catch-UP! following the person-based approach (PBA), a participatory intervention development methodology, and evaluates our use of this methodological approach for migrant participants.

Through engagement with both migrants and primary healthcare professionals (approximately 80–100 participants) via participatory workshops, focus groups and think-aloud interviews, the study aims to cocreate a comprehensive Health Catch-UP! implementation package. This package will encompass healthcare professional support materials, patient resources and potential Health Catch-UP! care pathways (delivery models), developed through iterative refinement based on user feedback and behavioural theory. The study will involve three linked phases (1) planning: formation of an academic–community coalition and cocreation of guiding principles, logic model and intervention planning table, (2) intervention development: focus groups and participatory workshops to coproduce prototype implementation materials and (3) intervention optimisation: think-aloud interviews to iteratively refine the final implementation package. An embedded mixed-methods evaluation of how we used the PBA will allow shared learning from the use of this methodology within the migrant health context.

Reusable menstrual products have gained increasing attention for their environmental and economic benefits, yet their uptake remains limited. University students represent a key demographic for understanding uptake, as young adults forming lifelong menstrual hygiene habits.

To synthesise evidence on university students’ knowledge, usage patterns and perceptions of reusable menstrual products, and identify barriers and facilitators to their adoption, to inform future interventions and educational efforts.

A systematic search of Medline, Embase, Scopus and Global Health was conducted, last updated on 31 October 2024.

Eligible studies contain data on perceptions of reusable menstrual products, specifically of students in university or higher education, or including segregated data on this population. Qualitative, quantitative and mixed-methods studies were included.

Two independent reviewers screened studies, extracted data and assessed methodological quality. All data were summarised descriptively.

10 studies (4721 participants) across multiple countries were included. Findings suggest that while reusable menstrual products are viewed by some as cost-effective and sustainable, barriers include concerns relating to practical usage and health, limited awareness, misconceptions and cultural taboos. In the university context, peer influence, financial constraints and sociocultural factors play a significant role in shaping product choices.

Targeted education to increase awareness and address practical concerns and misconceptions, alongside peer support and provision of reusable menstrual products, could significantly enhance the adoption of reusable menstrual products in university settings. Further research into the health impacts of these products would support educational interventions.
