Implementation Evaluation of a Diabetes Prevention Program Training Adolescents in Low-Income Communities to be Health Coaches for Family Members
This implementation study demonstrates that the Stanford Youth Diabetes Coaches Program (SYDCP) effectively empowers adolescents in low-income communities to become health coaches for their families, significantly improving health knowledge, behaviors, and psychosocial assets while highlighting the program's adaptability and feasibility through strong academic-community partnerships.

Chronic diseases like diabetes are rising across the United States, hitting low-income communities the hardest. These areas often face fewer resources for healthcare and struggle with higher rates of illness. A major hurdle in fighting this trend is the gap between what research says works and what actually happens in neighborhoods. Scientists have long known that family history plays a significant role in developing conditions like diabetes, and that improving health habits within a family can help prevent or manage these diseases. However, turning proven health strategies into everyday practice in underserved areas remains difficult. To bridge this divide, researchers are looking for ways to empower communities directly, often by turning to the next generation. Adolescents are uniquely positioned to influence their families, and when they learn about health, they can become powerful advocates for change within their own homes.
This study examines a specific effort to close that gap: the Stanford Youth Diabetes Coaches Program. The program operates on a simple but powerful idea. Instead of just teaching teenagers about healthy living, it trains them to become health coaches for their family members who already have diabetes or other chronic conditions. Medical trainees—doctors in training—visit high schools in low-income areas to teach these students. Over an eight-week period, the students learn how to talk to their relatives about diet, exercise, and managing their health. They then practice these skills by working one-on-one with a family member, helping them create plans to improve their daily lives. The goal is to improve the health of the family member while simultaneously building the teenager's confidence, communication skills, and knowledge.
The researchers wanted to understand how well this program works when it is actually put into practice across different parts of the country. They looked at six sites, ranging from urban centers in Washington, D.C., and California to rural areas in Alabama, Missouri, and Hawaii. Between 2020 and 2023, the program reached 517 high school students. The study focused on whether the program could be successfully adopted by schools and medical training centers, how smoothly it was implemented, and whether it could be sustained over time. They also measured whether the students themselves changed their knowledge and behaviors.
The results showed that the program was highly effective for the students involved. Among the 346 students who completed both the start and end surveys, there were significant improvements in almost every area measured. Their knowledge about health and diabetes grew substantially. They reported eating more fruits and vegetables, drinking fewer sugary beverages, and being more physically active. Beyond just physical habits, the students felt better about themselves. Their self-esteem, ability to solve problems, and confidence in managing their own lives all increased. Perhaps most importantly, the program changed how families talked about health. Students reported having more conversations with their family members about diabetes and health choices. In fact, 81 percent of the participants said they made a personal lifestyle change after finishing the program, and 85 percent felt the experience strengthened their relationship with the family member they were coaching.
The study also looked at the adults and organizations that made the program happen. The medical trainees who taught the classes found the experience valuable for their own professional development, helping them build communication skills and understand the realities of the communities they would serve. The schools and medical centers that hosted the program found it relatively easy to integrate into their existing schedules. The program was low-cost and flexible, able to be taught in person, online, or a mix of both. This adaptability was crucial, especially during the pandemic when some classes had to move to remote formats. The researchers found that the key to keeping the program running for years was strong partnerships between the schools and the medical centers, along with a clear alignment of goals. When the program fit the needs of the community and the goals of the institutions, it lasted.
Despite its success, the study noted some challenges. Finding time in busy school schedules and recruiting enough medical trainees to teach the classes were common hurdles. In some places, technology issues or transportation problems made it difficult to keep sessions running smoothly. However, these barriers were manageable through collaboration and by adjusting the program to fit local conditions. The researchers concluded that this model offers a reproducible way to engage young people as health advocates. By training adolescents to support their families, the program addresses diabetes disparities while building a bridge between medical professionals and the communities they serve. The findings suggest that with the right support and flexible strategies, evidence-based health programs can be successfully brought to resource-constrained settings, creating lasting benefits for both the youth and their families.
