Socioeconomically disadvantaged (SED) pregnant Latina women are disproportionately burdened by type 2 diabetes (T2D). Although lifestyle interventions can help to improve diabetes control, there are barriers to SED, Spanish-speaking pregnant people participating. The purpose of this proposal is to develop and test a culturally tailored, dietary-lifestyle behavioral intervention that supports eating plant-based foods such as fruits, vegetables, nuts and grains instead of processed foods and meat, and is implemented through community health workers (CHWs) to prevent excessive weight gain during pregnancy and improve control of blood sugar levels in pregnant Latina women with T2D. This study takes advantage of our existing strong relationships with the local Latino community, CHWs, and Santa Barbara County Public Health, which includes eight multidisciplinary healthcare clinics with sliding fee programs, and Rooted Santa Barbara, a community plant-based lifestyle organization. Cultural sensitivity focuses on delivering health information based on norms, values, beliefs, environmental factors, and historical context that is unique to a racial/ethnic population. Therefore, for our program to be culturally sensitive, it will include delivery of the program by CHWs primarily in the Spanish language with English as needed and incorporation of culturally relevant eating and physical activity recommendations. The specific aims of the project are: 1) in year one, develop the dietary-lifestyle behavioral intervention that encourages a plant-forward diet for pregnant Latina women with T2D to prevent excessive weight gain during pregnancy and improve blood sugar control in collaboration with CHWs and participants by conducting focus groups to incorporate feedback on the program; 2) initiate in year one, and in year two, conduct a randomized controlled trial with 30 pregnant Latina women with T2D to evaluate the how well the nutrition-behavior lifestyle program works; and 3) evaluate the acceptance and delivery of the dietary-lifestyle behavioral intervention in CHWs and participants. If successful, this study will establish the how well a culturally sensitive program delivered by CHWs incorporating plant-forward diets for pregnant Latina women with T2D prevents excessive weight gain during pregnancy, and control of blood sugar levels.

The purpose of this study is to evaluate the safety and effectiveness of the Hybrid Closed Loop system (HCL) in adult and pediatric patients with type 1 diabetes in the home setting. A diverse population of patients with type 1 diabetes will be studied. The study population will have a large range for duration of diabetes and glycemic control, as measured by glycosylated hemoglobin (A1C). They will be enrolled in the study regardless of their prior diabetes regimen, including using Multiple Daily Injections (MDI), Continuous Subcutaneous Insulin Infusion (CSII) or Sensor-Augmented Pump therapy (SAP) Read Less

The goal of this clinical trial is to compare those using a diabetes management smartphone application (mySugr) to those not using the application. This smartphone application is for Spanish-literate adults with poorly controlled, non-intensively treated type 2 diabetes. The main question[s] that it aims to answer are: What is the impact of the use of mySugr (a smartphone-based application or app) with structured blood glucose monitoring on diabetes self-management among Hispanic/Latino adults with poorly controlled, non-intensively treated T2D? Will diabetes self-management be more effective for those using mySugr (the Active group) compared to those not using mySugr (the Control group) over a 12-week study period? Participants will be screened and enrolled if they are eligible; they will have the study explained to them in Spanish or English and have time to ask questions and then sign an informed consent form. Clinical measurements (including height, weight, and blood pressure) and hemoglobin A1c will be done. All subjects will be given a blood glucose meter, lancing device, and blood glucose strips for the meter, and they will also receive an electronic scale. Several questionnaires will be answered. If a subject is randomly assigned to the Active group, they will download the mySugr Pro app in Spanish to their smartphone and be trained in its use. They will receive education focused on paired (before and 2 hours after a meal) blood glucose testing, which participants will conduct twice a day for 6 days and once a month for 3 months. Participants will continue structured blood glucose testing with the mySugr PRO app for 12 weeks, and they will have 3 virtual visits in Spanish with mySugr PRO coaches who will review the blood glucose records and advise the subjects. Subjects in the Control group will not receive the mySugr PRO app or coaching. They will continue with their usual diabetes management. All subjects will return after 12 weeks to return the scale and have a close-out visit with clinical measurements and questionnaires. Subjects will also receive a disturbance allowance for their time and participation. Read Less

In the United States, the growing Hispanic/Latino population is at high risk for type 2 diabetes and associated complications, yet underserved in healthcare and underrepresented in research. The purpose of this Sansum Diabetes Research Institute (SDRI) study is to create an HbA1c testing and support closed-loop system for U.S. Hispanic/Latino families. This loop will integrate Abbott's point-of-care (POC) technology with SDRI's Community Scientist Model to contact, test, intervene, and monitor Latinos with or at risk of type 2 diabetes for HbA1c levels. This study is built on prior work using specially trained Hispanic/Latino Community Scientists/Especialistas to support engagement with and encourage adherence to American Diabetes Association guidelines for HbA1c testing among Hispanic/Latino adults with type 2 diabetes. The study is an unblinded, nonrandomized, two arm self-controlled single center study. It is anticipated to run over 24 months and enroll 750 participants, in whom HbA1c will be measured over 6 months. This study will provide unique data on the burden of type 2 diabetes for Hispanic/Latino adults in Santa Barbara County, CA. In addition, the closed-loop approach will provide proof-of-concept evidence for scaling this approach to the larger Hispanic/Latino community to reduce the risk of poor outcomes due to type 2 diabetes and now COVID-19.
