Findings from Research

Culturally tailored diabetes prevention programs for Hispanic individuals in the U.S. have shown modest effectiveness, with nine out of twelve studies reporting significant weight reductions and two showing improvements in glucose regulation.

Interventions that included adaptations such as literacy modifications, use of Hispanic foods, and community involvement had the largest positive effects, highlighting the importance of cultural relevance in health programs.

Diabetes Prevention in U.S. Hispanic Adults: A Systematic Review of Culturally Tailored Interventions. McCurley, JL., Gutierrez, AP., Gallo, LC.[2021]

A home-based educational intervention for Hispanic adults with elevated HbA1c levels led to a significant reduction in HbA1c scores by -0.64% compared to -0.44% in the delayed intervention group, indicating its efficacy in improving glucose regulation.

The intervention did not significantly change dietary habits or overall physical activity levels, but there was a trend towards increased moderate and vigorous physical activity in the immediate intervention group, suggesting potential benefits in lifestyle changes.

The ¡Viva Bien! program, a culturally adapted health intervention for Latinas with type 2 diabetes, led to significant long-term improvements in lifestyle factors such as fat intake, body mass index, and hemoglobin A1c over a 24-month period.

Participants in the ¡Viva Bien! program also experienced enhancements in psychosocial outcomes and social-environmental support, although these effects tended to decrease over time, highlighting the need for ongoing support to maintain lifestyle changes.

A culturally tailored pharmacist intervention for Latino diabetics led to a significant reduction in BMI and hemoglobin A1c levels after three months, indicating improved management of diabetes-related health markers.

The intervention included personalized counseling on medication, nutrition, and self-care, which was adapted to fit cultural beliefs and practices, demonstrating the importance of culturally sensitive approaches in healthcare.

A community-based pilot study of a diabetes pharmacist intervention in Latinos: impact on weight and hemoglobin A1c. Castejón, AM., Calderón, JL., Perez, A., et al.[2022]

In a study involving 92 Hispanic women with prediabetes, a 12-month intensive lifestyle intervention (ILI) led to significantly greater weight loss (-4.0 kg) compared to metformin (-0.9 kg) and standard care (+0.8 kg), indicating that lifestyle changes may be more effective for weight management in this population.

The ILI group also showed a greater reduction in waist circumference and a marginal improvement in hemoglobin A1c levels compared to the other groups, suggesting that community health worker-led interventions could be a superior strategy for diabetes prevention among high-risk individuals.

A 14-week intensive lifestyle intervention (ILI) program adapted from the Diabetes Prevention Program led to a significant weight loss of 3.8 kg (4.4%) in Hispanic women with prediabetes, while the usual care group gained weight.

The ILI group also showed improved metabolic measures, including a 15 mg/dL decrease in two-hour glucose levels and significant reductions in BMI, body fat percentage, waist circumference, and fasting insulin after one year.

The study highlights both enabling factors and barriers faced by staff implementing a postpartum lifestyle intervention for Latinas at risk for type 2 diabetes, emphasizing the importance of cultural connection and flexible sessions in promoting participant engagement.

Barriers such as financial insecurity, low health literacy, and participant resistance to behavior change were significant challenges, suggesting that future interventions need to address these contextual issues to improve adherence and effectiveness.

The study aims to evaluate a culturally-grounded lifestyle intervention for Latino families, involving 132 participants, to improve glucose tolerance and quality of life over 12 months.

The intervention includes 16 weeks of nutrition and wellness classes led by bilingual professionals and supervised physical activities, which may enhance family engagement and empowerment in diabetes prevention.
