Noom Health for Weight Management
Study Details
Study Description
Brief Summary
The goals of the study are to use the Noom mobile app to help individuals with weight loss and weight loss maintenance. This project will test the comparative efficacy of Noom Health vs. Noom Digital Health for weight loss, quality of life, psychosocial functioning, and self-reported health status. It is expected that use of Noom Health will show post-intervention success relative to Noom Digital Health as well as long-term success with weight loss maintenance. Data is expected to show that participants who are older, have less support, have more health conditions, and with more psychosocial problems will benefit more from Noom Health. It is also expected that confidence in the ability to lose weight will produce more successful results in Noom Health vs. Noom Digital Health.

Detailed Description
A total of 600 subjects will be enrolled in a randomized-controlled trial comparing the Noom app (Noom Health) to a digital control (Noom Digital Health) with 6 months of intervention and 6 months active maintenance in both groups. Measures will include demographics, psychosocial measures, height/weight, waist circumference, weight loss history/practices, health care practices/utilization, and quality of life.
Participants will complete informed consent and interviews via a HIPAA-compliant videoconference (Zoom) and other questionnaires via a REDCap interface. All participants will complete screening/baseline procedures to determine eligibility and initial information. Subsequently, they will be randomized to one of the groups for a 6-month intervention and 6- month maintenance period (12 months total).
In Noom Health, participants will be encouraged to use the app multiple times per day to log eating episodes, physical activity and weight. Coaches will also interact with participants directly through the app. In Noom Digital Health, participants will use a simplified version to log eating episodes and weight. Both conditions will receive the same weight loss advice content.
During the intervention, participants will complete monthly satisfaction surveys. Additionally, follow-up measures will be conducted at 7 time points (Screening/Baseline, 1 month, 4 months, 6 months, 12 months, 18 months, 24 months, and 30 months).

Outcome Measures
Primary Outcome Measures
- Change in Weight from Baseline to 6 Months [Baseline and 6 Months]
Weight at 6 months as compared to baseline. Weight will be documented using staff-led Zoom calls and taken with the participant's home scale.
- Change in Weight from Baseline to 24 Months [Baseline and 24 Months]
Weight at 24 months as compared to baseline. Weight will be documented using staff-led Zoom calls and taken with the participant's home scale.
Secondary Outcome Measures
- Change in Caloric Intake using the Automated Self-Administered Recall System (ASA24) from Baseline to 24 months [Baseline and 24 Months]
Caloric intake at 24 months as compared to baseline. Caloric intake will be measured using the ASA24 dietary recall system.
- Change in Dietary Behavior using the Eating Disorder Examination Questionnaire (EDE-Q) from Baseline to 24 Months [Baseline and 24 Months]
EDE-Q global score at 24 months as compared to baseline. Dietary restraint, eating, shape, and weight concerns are measured with the EDE-Q. These subscales are summed and then divided by the total number of subscales (4) to create a global score. Scores range from 0 to 52 with higher scores indicating higher severity.
- Change in Physical Activity using the International Physical Activity Questionnaire (IPAQ) from Baseline to 24 Months [Baseline and 24 Months]
Physical activity at 24 months as compared to baseline. The IPAQ includes 27 items and determines a MET value for time spent in an average week completing different levels of activity including vigorous or moderate physical activity, walking, and sitting. One MET is the energy spent sitting at rest.
- Change in Depression using the Depression Anxiety Stress Scales (DASS) from Baseline to 24 Months [Baseline and 24 Months]
Depression subscale score at 24 months as compared to baseline. DASS is a 42-item self-report scale of negative emotional states with subscales of depression, anxiety, and stress. Each subscale is scored 0-42, with total score from 0-126. Higher scores indicate more severe psychological distress.
- Change in Anxiety using the Depression Anxiety Stress Scales (DASS) from Baseline to 24 Months [Baseline and 24 Months]
Anxiety subscale score at 24 months as compared to baseline. DASSis a 42-item self-report scale of negative emotional states with subscales of depression, anxiety, and stress. Each subscale is scored 0-42, with total score from 0-126. Higher scores indicate more severe psychological distress.
- Change in Stress using the Depression Anxiety Stress Scales (DASS) from Baseline to 24 Months [Baseline and 24 Months]
Stress subscale score at 24 months as compared to baseline. DASS a 42-item self-report scale of negative emotional states with subscales of depression, anxiety, and stress. Each subscale is scored 0-42, with total score from 0-126. Higher scores indicate more severe psychological distress.
- Change in Sleep Impairment using the PROMIS Sleep Related Impairment Survey from Baseline to 24 Months [Baseline and 24 Months]
Sleep impairment at 24 months as compared to baseline. The PROMIS Sleep Related Impairment v.1.0 is a 16-item self-report measure of perceived functioning during waking hours in relation to tiredness and trouble sleeping. A raw score is calculated by summing all individual items and is translated into a T-score with standard error (SE). A T-score of 50 indicates normal impairment compared to the general population, scores above 50 indicate more impairment.
- Change in Physical Composite Score (PCS) using the Short-Form-36 (SF-36) from Baseline to 24 Months [Baseline and 24 Months]
PCS at 24 months as compared to baseline. The SF-36 is a 36-item self-report health-related quality of life assessment of physical functioning, limitations, energy, emotional well-being, social functioning, pain and general health. Scores range from 17.2- 66.7 with lower scores indicating worse quality of life related to physical health.
- Change in Mental Composite Score (MCS) using the Short-Form-36 (SF-36) from Baseline to 24 Months [Baseline and 24 Months]
MCS at 24 months as compared to baseline. The SF-36 is a 36-item self-report health-related quality of life assessment of physical functioning, limitations, energy, emotional well-being, social functioning, pain and general health. Scores range from 12.7-64.2 with lower scores indicating worse quality of life related to mental health.
- Change in Self-Efficacy for Healthy Eating using the Diet Self-Efficacy Scale (DIET-SE) from Baseline to 12 Months [Baseline and 12 Months]
Self-efficacy at 12 months as compared to baseline. The DIET-SE is an 11-item self-report assessment of healthy eating with scales specific to temptations, social/internal factors, and negative emotional related to resistance. The score ranges from 0 - 40 with higher scores indicating more self-efficacy.
- Adherence to intervention measured using a percentage of the total number of available app features used from Baseline to 12 Months [Baseline and 12 Months]
The percent of available features on the app, expected verses completed at 12 months as compared to baseline.
- 12-Month Completion Status [Baseline and 12 Months]
Attrition at 12 months as compared to number randomized at baseline documented using completion status
- Percent of Successful Technological Fixes [Baseline and 12 Months]
App compatibility will be examined by calculating the percent of successful technological fixes at 12 months as compared to baseline. The type of technological problems encountered by participants while using the app and any fixes needed will be categorized.
- Change in CDC NCHS National Health Interview Survey [Baseline and 24 Months]
Changes in health status from baseline to 24-months as measured by questions from the CDC NCHS National Health Interview Survey. Using an adapted version of the CDC NCHS National Health Interview Survey, the survey includes 4 questions about healthcare utilization. Items identify type of healthcare sought and frequency. The frequency of provider visits will be calculated to determine healthcare utilization. A frequency score of zero indicates no healthcare utilized. There is no upper limit for the frequency.
