Vida Sana y Completa: A randomized controlled trial to examine the effectiveness of diabetes prevention with and without medically supportive groceries among Latina women.

Latina women have a high prevalence of obesity and obesity-related chronic diseases, such as diabetes. Approximately half of Latinas with obesity will also experience food insecurity, or a lack of access to enough food for an active and healthy life. Food insecurity is a barrier for effective prevention and management of obesityrelated chronic diseases. The goal of this type 1 hybrid comparative effectiveness trial is to compare a culturally-tailored diabetes prevention intervention with and without medically supportive groceries. Adult Latina women (n = 412) with obesity (Body Mass Index (BMI) of >30 kg/m(2)) and food insecurity will be 1:1 randomized to the Vida Sana intervention (control), or to Vida Sana y Completa (intervention plus integrated treatment for food insecurity). Vida Sana is an evidence-based culturally tailored, 12-month diabetes prevention intervention that targets at least 5% weight loss and at least 150 min/week of moderate-to-vigorous physical activity. Participants enrolled in Vida Sana y Completa will also receive 12 weekly deliveries of medically supportive groceries. Those in Vida Sana alone will receive information on local food resources. Participants will be assessed at baseline and every 6 months for 24 months. The primary outcome is weight loss at 12 months. Secondary outcomes include weight loss maintenance, diet quality, and quality of life. Barriers and facilitators of implementation will be assessed using mixed methods according to the Consolidated Framework for Implementation Research. This study will provide critical evidence for addressing the combination of obesity and food insecurity in primary care for diabetes prevention. Trial Registration: NCT052111.
