About

The goal of the Vida Sana y Completa study is to provide evidence on the most effective approach for addressing the critical combination of obesity and food insecurity among Latinas in primary care while also collecting preliminary information on the potential for implementation and dissemination.

Full description

The goal of this study is to compare two approaches to addressing obesity and food insecurity among Latina women in primary care to provide evidence for community health centers who serve this high-priority group. The project team will recruit 412 low-income Latina women with obesity (body mass index 30) and food insecurity from two community health centers with whom the team has longstanding partnerships. Patients will be randomized to Vida Sana y Completa (an obesity intervention with integrated treatment for food insecurity) or Vida Sana alone. Vida Sana is a state-of-the-art cultural adaptation of Group Lifestyle Balance, a 12-month program that targets at least 5 percent weight loss and at least 150 minutes per week of moderate-to-vigorous physical activity. For food insecurity, the team will provide boxes of healthy foods (e.g., fresh produce, lean protein, low-fat dairy, and whole grains) that give women the foods they need to adopt a healthy diet.

412 participants in 2 patient groups

Vida Sana

Active Comparator group

Description:

Vida Sana is a cultural-adaption of Group Lifestyle Balance, a 12-month intervention that targets at least 5% weight loss and at least150 minutes per week of moderate-to-vigorous physical activity. Health coaches will facilitate 12 weekly 1-hour group education sessions, followed by nine 30-45 minute individual monthly phone sessions. Health coaches will also conduct two home visits (at baseline and 12-weeks post-enrollment). The health coach will review participant's fitbit health tracking data with them and give personalized feedback.

Treatment:

Behavioral: Vida Sana

Vida Sana y Completa

Experimental group

Description:

Vida Sana y Completa is an obesity intervention with integrated treatment for food insecurity. This arm includes all the activities described for the active comparator arm (Vida Sana) as well as a weekly food box delivery for the first 12 weeks of the intervention. The food box will contain approximately 40 pounds of food including proteins and dairy, whole grains, and produce. Just like the Vida Sana active comparator arm, the Vida Sana y Completa group will include health coaches who will facilitate 12 weekly 1-hour group education sessions, followed by nine 30-45 minute individual monthly phone sessions. Health coaches will also conduct two home visits (at baseline and 12-weeks post-enrollment). The health coach will review participant's fitbit health tracking data with them and give personalized feedback.

Behavioral: Vida Sana y Completa
