Native American Diabetes Project (NADP)

January 17, 2025 updated by: Claradina Soto, University of Southern California

Community Partnered Medical Nutrition Intervention for Native Americans Living with Diabetes

This research study is for American Indian and Alaska Native (AIAN) people with diabetes in Los Angeles County, California. Participants (people who join the study) are signed up for a program that includes healthy meals, online diabetes classes, and social support.

This study aims to answer the following question:

Can this program (the meals, classes, and social support) have health and well-being benefits for participants, like lower blood sugar levels and less social isolation?

Participants are asked to fill out surveys and go to three clinic visits. Participants do not have to pay for the clinic visits or any other parts of the study.

Detailed Description

Diabetes in the American Indian and Alaska Native (AIAN) population is a public health crisis. AIAN have the highest diabetes prevalence rates when compared to other racial and ethnic populations in the United States. According to the Centers for Disease Control and Prevention, 14.7% of AIAN adults compared to 7.5% of non-Hispanic Whites have been diagnosed with diabetes. In California (CA), those who self-identify as having CA Tribal heritage are twice as likely than individuals from tribes outside of CA to be diagnosed with diabetes (31% versus 16%). Significant disparities also exist in diabetes-related outcomes. Compared to the general population, AIANs are 2.3 times more likely to die from diabetes, and the incidence of diabetes-related kidney failure among AIANs is 2.0 times higher. Cardiovascular disease among AIANs with diabetes may be 3-8 times higher than those AIAN without diabetes.

The diabetes crisis among AIAN is best addressed using a holistic approach. Aside from addressing the impact of diabetes on several physical health outcomes, best practices also include addressing the impact of trauma and mental and emotional health, providing robust patient education, and addressing structural barriers such as food insecurity, lack of access to healthy food, living in poverty, limited social support, and lack of access to health care, especially that which is culturally responsive.

Given the disproportionate rates of diabetes and diabetes-related outcomes among AIANs, this is the perfect opportunity to provide a culturally tailored health promotion intervention among the largest urban AIAN population in the U.S.; approximately 171,163 AIANs reside in Los Angeles County.

The goal of this pilot study was originally to reach up to 312 Native Americans with diabetes (later reduced, aiming for 150) to participate in an intervention to lower blood sugar and feelings of social isolation. The intervention will include 12 weeks of diabetes-friendly, medically tailored meals, and four weeks of virtual diabetes wellness classes. Each participant will be part of a 180-day cohort, during which participants will complete surveys and attend three clinic visits.

Plan to Share Individual Participant Data (IPD)?

NO

IPD Plan Description

While we understand the value of data sharing, research with Native American communities is particularly sensitive due to data sovereignty and past abuses, including the use of Native people's data for purposes the people didn't know about or agree to, sometimes causing harm to the community. Our informed consent states that even deidentified participant data will not be used or distributed for further studies. We made this choice out of respect for the data considerations here and also to ensure potential participants feel as comfortable as possible when participating, as recruitment can already be challenging.
