Culturally Competent Diabetes Self-Management Education for Mexican Americans

TLDR

The study aimed to assess the impact of a culturally competent diabetes self‑management program on Mexican Americans with type 2 diabetes. A randomized, prospective study of 256 Mexican American adults on the Texas‑Mexico border enrolled participants with type 2 diabetes and a family member, delivering 52 hours of bilingual, culturally tailored education and support over 12 months, and measured HbA1c, fasting glucose, knowledge, and beliefs. Participants receiving the intervention achieved significantly lower HbA1c and fasting glucose at 6 and 12 months, with a 1.4 % reduction at 6 months, and improved diabetes knowledge, confirming the program’s effectiveness, especially for those with baseline HbA1c > 10%.

Abstract

OBJECTIVE—To determine the effects of a culturally competent diabetes self-management intervention in Mexican Americans with type 2 diabetes. RESEARCH DESIGN AND METHODS—A prospective, randomized, repeated measures study was conducted on the Texas-Mexico border in Starr County. A total of 256 randomly selected individuals with type 2 diabetes between 35 and 70 years of age, diagnosed with type 2 diabetes after 35 years of age, and accompanied by a family member or friend were included. The intervention consisted of 52 contact hours over 12 months and was provided by bilingual Mexican American nurses, dietitians, and community workers. The intervention involved 3 months of weekly instructional sessions on nutrition, self-monitoring of blood glucose, exercise, and other self-care topics and 6 months of biweekly support group sessions to promote behavior changes. The approach was culturally competent in terms of language, diet, social emphasis, family participation, and incorporation of cultural health beliefs. Outcomes included indicators of metabolic control (HbA1c and fasting blood glucose), diabetes knowledge, and diabetes-related health beliefs. RESULTS—Experimental groups showed significantly lower levels of HbA1c and fasting blood glucose at 6 and 12 months and higher diabetes knowledge scores. At 6 months, the mean HbA1c of the experimental subjects was 1.4% below the mean of the control group; however, the mean level of the experimental subjects was still high (>10%). CONCLUSIONS—This study confirms the effectiveness of culturally competent diabetes self-management education on improving health outcomes of Mexican Americans, particularly for those individuals with HbA1c levels >10%.
