Large-scale health behaviour surveillance studies face recruitment challenges^{1, 2}, particularly in global studies involving young children across diverse cultural contexts^3,4. The SUNRISE study is a global surveillance study of 24-hour movement behaviours in children aged 3 – 5 years, which creates a unique opportunity to evaluate recruitment strategies⁵. This study aimed to identify recruitment strategies and barriers across participating countries, examine associations with recruitment success, and explore regional, income, parent, and centre related patterns. In doing so, novel cross-national insights into recruitment practices in global health research are provided.

A qualitative design guided by the socio-ecological model is adopted to classify recruitment strategies and barriers. The sample included 51 countries participating in SUNRISE. Data were collected via an online survey comprising of open-ended questions. Countries completed the pilot and main study phases were invited to complete the survey twice. Data analysis applied directed content analysis framed within the socio-ecological model.

Sixty survey responses were received from 48 countries. Interpersonal strategies were most common for centre and parent recruitment, emphasising rapport and commitment. Centre recruitment barriers were mainly organisational and public-policy related. Solutions included responsive communication and governmental endorsement. Parent recruitment barriers were primarily intrapersonal, highlighting knowledge and perception gaps. These were addressed through trust-building, engagement, and knowledge development.

This cross-national study identifies key recruitment strategies and barriers in a global early childhood surveillance study. Findings will inform evidence-based, culturally responsive recruitment approaches and support the design and implementation of future global child health surveillance and intervention studies.
