Vida Sana y Completa Obesity and Food Insecurity Study

Vida Sana y Completa Trial: Treating Obesity and Food Insecurity Among Latina Women

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.

Study Overview

• Status: Recruiting
• Conditions: Obesity
• Intervention / Treatment: Behavioral: Vida Sana; Behavioral: Vida Sana y Completa

Detailed 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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Vida Sana; 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.	Behavioral: Vida Sana; Weekly group or individual education sessions with a health coach and fitness tracking with a fitbit.
Experimental: Vida Sana y Completa; 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; Weekly group or individual education sessions with a health coach, fitness tracking with a fitbit, and weekly food box delivery.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Weight change (12 months)	Trained research assistants blinded to treatment assignment will weigh participants in duplicate using a standard calibrated scale at baseline, 12, and 24 months	Baseline, 12 months, 24 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Self-reported weight	Participants will self-report measures of weight at 6 and 18 months to the health coach via telephone.	6 months, 18 months
Visit or EHR Height, Weight, and Waist Circumference	In person visits at baseline, 12-months and 24-months post enrollment will be used to collect participant weight, height and waist circumference. At baseline, these will be measured twice or in triplicate if there is a discrepancy. Height will be measured in centimeters, weight will be measured in kilograms, and waist circumference will be recorded in centimeters. If participants cannot be weighed in person for the primary outcome, weight measurement from the EHR if available within 3 months of the data collection date will be used. Waist circumference will be measured according to standard protocols described by the National Health and Nutrition Examination Surveys (NHANES) Anthropometry Procedures Manual. http://www.cdc.gov/nchs/data/nhanes/nhanes_11_12/Anthropometry_Procedures_Manual.pdf. Published 2011.	baseline, 12 months, 24 months
Health-related quality of life	The validated SF-8™ will be used. It is a generic multipurpose short-form health-related quality of life instrument and was developed by the RAND Corporation and the Medical Outcomes Study (MOS) in the 1980s.	baseline, 6 months, 12 months, 24 months
Obesity-specific quality of life	Obesity-related Problem Scale, average scores of 8 questions with a range from 0 (no at all) to 3 (extremely). The average score is then multiplied by 100 and divided by 3 to convert to a scale of 0-100, with a higher score indicating more obesity-related problems. Obesity-related quality of life measured at baseline, 6 months, 12 months and at 24 months.	baseline, 6 months, 12 months, 24 months
Change in Psychosocial Well-being: Depressive Symptoms	The Patient Health Questionnaire PHQ-9 is a self-report questionnaire with 9 items plus a 10th question. Respondents answered questions regarding how often a symptom has bothered them over the last two weeks. Each item is rated on a 4-point scale (0 = not at all, 1 = several days, 2 = more than half the days, 3 = nearly every day). PHQ-9 total score is the sum of the nine items, ranging from 0 to 27. Scores of 5, 10, 15, and 20 represent cut-points for mild, moderate, moderately severe and severe depression, respectively. PHQ-9 score at baseline, 6 months, 12 months and at 24 months.	baseline, 6 months, 12 months, 24 months
Cardiometabolic risk factors	Waist circumference will be measured at baseline, 12 months and at 24 months according to standard protocols described by the National Health and Nutrition Examination Surveys (NHANES) Anthropometry Procedures Manual. http://www.cdc.gov/nchs/data/nhanes/nhanes_11_12/Anthropometry_Procedures_Manual.pdf. Published 2011. Accessed October 29, 2014. At baseline, 12 months and at 24 months blood pressure will be measured twice by a trained health coach, a third if there is a discrepancy. Blood pressure, fasting glucose, HbA1c, and lipids will be pulled from the medical record for each time point.	baseline, 6 months, 12 months, 24 months
Participant Medication Usage	Participants will be asked to self-report medications/prescriptions. A list of prescribed medications will also be pulled from the electronic health record.	baseline, 12 months, 24 months
Dietary Intake Patterns	Dietary intake will be measured using the gold-standard approach of 3 multiple pass 24-hour recalls (2 during the weekday and 1 on the weekend at each time point). The Nutrition Data System for Research (NDSR), a validated approach, will be used. Changes in dietary intake over 24-months will be assessed.	baseline, 6 months, 12 months, 24 months
Food Neophobia Scale	The Food Neophobia Scale (FNS) is a 10-item questionnaire that is comprised of likert type items ranging from "strongly disagree (1)" to "strongly agree (7)." Participants indicate their level of agreement for statements such as "I will eat almost anything" with higher scores indicating greater agreement per item.	baseline, 6 months, 12 months, 24 months
Food Attitudes & Behaviors (FAB) Scale for self-efficacy	A subset of 7 items regarding Self-Efficacy to Eat Fruits and Vegetables will be used from the validated Food Attitudes & Behaviors (FAB) scale. These items are answered on a likert scale from "not at all confident" to "very confident" with an option for "does not apply." Scoring details are available on the NIH website (https://cancercontrol.cancer.gov/brp/hbrb/food-attitudes-and-behaviors).	baseline, 6 months, 12 months, 24 months
Second Harvest of Silicon Valley Food Bank Self-Efficacy Measure	Two self-reported items from the Second Harvest of Silicon Valley food bank self-efficacy questionnaire will be asked. They are "In the past few months, have you tried a new recipe using food you received at a free food distribution?" and "And have you tried a new fruit or vegetable that you received at a free food distribution?" Answer choices are yes, no, or I did not receive food.	baseline, 6 months, 12 months, 24 months
Participant self-reported 7-day Physical Activity Recall	The research team will administer the 7-day Physical Activity Recall, a self-report measure of physical activity and sleep.	baseline, 6 months, 12 months, 24 months
Participant steps per day	Steps per day will be verified with data from the Fitbit Alta HR used to calculate steps per day.	baseline, 6 months, 12 months, 18 months, 24 months
Number of participants with food insecurity	The USDA 6-item brief food security measure is a validated tool for assessing household food security. Food security status for each participant at 5 time points over 24 months will be recorded.	baseline, 6 months, 12 months, 18 months, 24 months
Self-reported Nutrition Security, Healthfulness Control, and Utilization Barriers Survey Tool	Each participant self-report answers 4 self-report nutrition security questions, 2 questions about control over the food consumed, and 2 questions about barriers over the last 12 months. Answers choices are a likert scale from Never=0 to Always=4 with higher scores indicating lower levels of nutritional security. Sample item: "In the last 12 months, (I/we) had to eat some foods that were not good for (my/our) health and well-being because (I/we) could not get other types of food."	baseline, 6 months, 12 months, 18 months, 24 months
Stunkard Figure Rating Scale	Motivation for weightloss will be measured using the Stunkard Figure Rating Scale. This validated tool uses a diagram showing figures of various shapes and sizes and asks the participant to indicate their current body type and the type they would most like to be. Participants are asked to: (1) choose your ideal figure; (2) choose the figure that reflects how you think you look; (3) choose the figure that reflects how you feel most of the time; (4) choose the figure that you think is most preferred by men; (5) choose the figure that you think is most preferred by women; and (6) pick the opposite sex figure that you find most attractive. Scoring uses discrepancy measures: (1) feel minus ideal; (2) think minus ideal; and (3) feel minus think Thompson, J.K., & Altabe, M.N. (1991). Psychometric qualities of the figure rating scale. International Journal of Eating Disorders, 10(5), 615-619.	baseline
Level of anxiety among participants	The validated Generalized Anxiety Scale (GAD-7) will be administered to measure the severity of anxiety that may be present among participants. The GAD-7 score is calculated by assigning scores of 0, 1, 2, and 3, to the response categories of 'not at all', 'several days', 'more than half the days', and 'nearly every day', respectively, and adding together the scores for the seven questions. Scores of 5, 10, and 15 indicate mild, moderate and severe anxiety, respectively.	baseline, 6 months, 12 months, 24 months
Bidimensional Acculturation Scale for Hispanics	This validated self-report 24-item tool will be used to understand how participants communicate in both English and Spanish. Each item is a likert-type with answer choices asking participants to rate the frequency they use a communication practice. Answers range from "Almost always (4)" to "Almost never (1)" or "Very well (4)" to "Very Poorly (1)."	baseline
COVID-19 Impact on Health and Wellbeing Survey for Health Literacy	Four items were selected from the COVID-19 Impact on Health and Wellbeing Survey to capture how participants receive and process health information such as level of comfort with health forms, medical information, and visiting the doctor.	baseline
