摘要

Background

Diabetes is a rising but preventable health concern in Latin America and the Caribbean, where healthy eating research and behavioral interventions are crucial to reducing its global health burden. This study aimed to explore perceived barriers and facilitators of healthy eating, explain their underlying psychosocial mechanisms with the Theoretical Domains Framework and identify relevant behavioral interventions.

Methods

A multimethod qualitative Photovoice study was conducted to identify themes related to healthy eating barriers and facilitators. The Theoretical Domains Framework was used to explain the psychosocial mechanisms explaining barrier and facilitator themes, and identify behavior change techniques.

Results

Thirteen participants contributed 48 photos for analysis. The multimethod triangulation between thematic and content analysis highlighted that barriers are concentrated around structural factors such as the socioeconomic context, while facilitator’s themes are less concentrated and have a higher code frequency supporting skills, knowledge and personal factors. The environmental context, social role and influences were core TDF domains explaining barriers. The TDF domains explaining facilitators were more heterogeneous with social influences and environmental context, knowledge and belief about consequences being the core psychosocial mechanisms explaining facilitators. Restructuring the physical and social environment where the main behavioral interventions relevant to the overall sample. Additionally, modelling the desired behavior and simultaneously providing instruction on how to perform the behaviour, especially by peers in the social network, were also relevant to the sample.

Conclusion

These findings unique to Latin America and the Caribbean reveal the potential of participatory research to provide insights into local healthy eating behavioral etiology to inform small-scale interventions and personalized behavioral interventions. Furthermore, primary health care teams conducting home visits could use this information to employ behavioral change techniques beyond providing or discussing information to community members.
