Health Promotion Practice, Ahead of Print.
Tens of thousands of trucks cross the U.S.–Mexico border every day. Cross-border truckers’ high mobility puts them at risk of acquiring and transmitting infectious diseases and creates challenges reaching them with emergency public health messaging due to their everchanging locations and limited English proficiency. Despite this community-level transmission risk and documented health disparities related to various infectious and noninfectious diseases experienced by truckers themselves, little has been published to provide practical recommendations on better reaching this audience through innovative outreach methods. This article describes a COVID-19 health promotion campaign that aimed to (1) identify, pilot test, and evaluate effective messages, channels, sources, and settings for reaching truckers on both sides of the U.S.–Mexico border and (2) build capacity and sustainability for messaging around future health emergencies. The pilot program ran for 6 weeks, June to August 2023, in three key commercial border crossings and delivered approximately 50,000,000 impressions, nearly 45% more impressions than expected. Considerations for practitioners include the areas of design, implementation, and evaluation. The results provide insight into how to design health promotion messages that resonate with cross-border truckers and how to place these messages where they will be seen, heard, and understood. This includes working effectively with community health workers (CHW), known locally as promotores; identifying local partners that allow CHW to set up onsite; and, working with partner organizations including employers. Practical insights for building evaluation metrics into traditional and grassroots outreach strategies to facilitate real-time optimization as well as continued learning across efforts are also described.
