INTRODUCTION:
The health impacts of hazardous work and precarious employment on low wage migrant workers, the world’s largest migrant group, remain severely under-researched. Some evidence shows that migrants face disproportionate risks of workplace injury and elevated morbidity and mortality, which exacerbates global health inequalities as technological, economic, environmental, and political transitions accelerate. Despite this, migrant workers remain largely invisible in health metrics, surveillance systems, and interventions. Addressing this systematic neglect is essential for equitable and inclusive health protections. This project aims to develop migrant-sensitive survey instruments to generate burden estimates and support worker-centred health interventions.

METHODS:
Building on long standing collaborations with interdisciplinary academics, UN agencies, and migrant worker networks, we are conducting a multi-site programme in Egypt, Malaysia, and the UK using transdisciplinary methods and community engagement and involvement. First, we are synthesising existing evidence through systematic reviews, policy analyses, and assessments of national health and occupational data systems. Second, we will co-develop standardisable work–health indicators through regional expert workshops and nominal consensus techniques, validating and translating them into survey modules to generate prevalence estimates for policy implementation. We will then co-design site-specific interventions (i.e.,mobile clinics, insurance schemes, heat stress protocols) and evaluate them using rapid realist evaluations. Expected

RESULTS:
Our programme will produce validated, cross-culturally relevant indicators aligned with ILO, WHO, and GBD frameworks; robust prevalence estimates of exposures, service use, and health outcomes; and comparative insights into the effectiveness, feasibility, and scalability of priority interventions. Outputs will include open access survey tools, implementation guides, and co-designed intervention prototypes disseminated through a Migrant Worker Health Evidence-to-Action Platform.

DISCUSSION:
By closing critical measurement gaps and embedding worker-centred design, this project will enable scalable, policy relevant protections and more inclusive health systems for migrant workers. As climate change and conflict intensify displacement, these innovations will be vital for global health security.
