A Case Study on the Dietary Shifts in an Older Tongan Migrant to the United States.

This case study, anchored in the Social Ecological Model (SEM), delves into the dietary behaviors of a 67-year-old first-generation Tongan woman in Utah. It uncovers pivotal themes through narrative and thematic analysis: cultural identity, economic constraints, environmental adaptation, and health perceptions. The study underscores the importance of cultural preservation, economic stability, and the centrality of traditional Tongan foods, revealing a complex interplay between cultural adaptation and health awareness. Community support and engagement emerged as crucial in sustaining healthy dietary practices amid cultural changes. The study advocates for an SEM-based framework to guide future research and develop culturally sensitive interventions to improve dietary behaviors among first-generation Tongan immigrants and similar groups and offers valuable insights. The limited generalizability of this study due to its single-case design necessitates future investigations to incorporate broader and more diverse samples to validate the findings and tailor more precise interventions.
