This document summarizes a literature review on perceived barriers to lifestyle changes among Hispanic Americans with type 2 diabetes. It finds that cultural, sociocultural, and psychobehavioral factors like familismo, diet/exercise barriers, and self-efficacy influence diabetes management. Barriers include lack of social support, high costs, and limited access to care or providers who understand patients' language and culture. Perceived barriers may differ between Hispanic subgroups and genders. Understanding these barriers can help tailor effective diabetes interventions for Hispanics.
