PURPOSE: This study explored self-reported barriers to diabetes self-management in a population of urban, low-income Puerto Rican individuals. METHODS: A cross-sectional exploratory survey was conducted with 30 Puerto Rican adults with type 2 diabetes. Participants were randomly selected and recruited from a health center, an elder center, and a community outreach database. A survey was used to assess participants' diabetes-related knowledge, attitudes, and patterns of and barriers to self-management. RESULTS: Participants were older and had limited education and good access to health care. Although two thirds had participated in diabetes education, most demonstrated major deficits in diabetes knowledge. Negative attitudes about living with diabetes were common as was dietary knowledge and nonadherence. Most participants were overweight or obese, did regular self-monitoring of blood glucose but did not use the results to improve their diabetes control, and frequently missed doses of their diabetes medications. Self-reported barriers to self-management were financial and social obstacles and competing health and family concerns. CONCLUSIONS: The knowledge and self-management behaviors in this population of Puerto Rican individuals with type 2 diabetes need to be improved.
