Stanford University412 enrolled

Overview

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.

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.

Outcomes

Primary Outcomes

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

Time frame: Baseline, 12 months, 24 months

Secondary Outcomes

Self-reported weight

Participants will self-report measures of weight at 6 and 18 months to the health coach via telephone.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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).

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.

Time frame: 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.
