Abstract
Purpose: Many East Asian Americans (EAAs) (populations originating from China, Korea, Japan, and Taiwan) with type 2 diabetes mellitus (T2DM) experience unique challenges in managing their disease, including language barriers and traditional cultural beliefs, particularly among first-generation immigrants. The purpose of this mixed-methods systematic review was to examine cultural perspectives of EAAs that influence dietary self-management of T2DM and identify education interventions and their approaches to enhance EAAs' dietary self-management of diabetes.
Methods: A mixed-methods systematic review was conducted to examine EAAs' perspectives from qualitative studies and to identify education interventions and their approaches from quantitative studies. A literature search was conducted using PubMed/MEDLINE, SCOPUS, CINAHL, and Web of Science from 1995 to 2018. Sixteen studies (10 qualitative and 6 quantitative) met criteria for analysis. Thematic synthesis of qualitative data was conducted using a line-by-line coding strategy. Extracted quantitative data were assessed for cultural approaches used in the interventions and diabetes-related outcomes.
Results: In the qualitative studies, beliefs about food impacted EAAs' abilities to adopt appropriate dietary recommendations for diabetes management. Requiring a specialized diet disrupted social harmony and made EAAs feel burdensome to others. Having bilingual and bicultural resources eased the stress of making dietary modifications. The most commonly incorporated approaches in diabetes education interventions were bilingual education and culturally specific dietary recommendations. Social roles and harmony were not discussed. Significant reductions in hemoglobin A1c and increases in diabetes knowledge were reported post-intervention.
Conclusions: Beliefs about food, beliefs about social roles, and access to culturally competent care play an important role in dietary self-management of T2DM among EAAs. Understanding the cultural influences on dietary self-management of T2DM and tailoring interventions to meet the needs of EAAs are essential in effort to address the growing epidemic and improve patient outcomes.
