M-POWER Feasibility Study (M-POWER)

Mobile - PrOmoting Wellness After cancER Study: M-POWER Feasibility Study

The purpose of this study is to test a new weight loss intervention designed for cancer survivors who have heart disease or cardiometabolic conditions. The investigators want to determine whether this study is feasible and acceptable to participants. The investigators also want to learn more about how cancer survivors take their medications.

Study Overview

• Status: Completed
• Conditions: Adherence, Patient; Weight Reduction
• Intervention / Treatment: Behavioral: Interventional Behavioral Arm

Detailed Description

The purpose of this study is to test a new weight loss intervention designed for cancer survivors. The investigators want to determine whether this approach to weight loss is feasible and acceptable to cancer survivors. All participants in the study will receive free behavioral telephone-based weight loss management in the Department of Preventive Medicine at Northwestern University. Participants must be willing and able to use their smartphone with Bluetooth and their WiFi to download Apps, set up a Fitbit account and a Google account if not already set up. Participants will use their smartphone to record food intake & physical activity over an 8 week weight loss program. This program includes recruitment of a "Buddy" that the participant will choose to support you during the 8 week study.

All participants will be asked to download a study application to use to record dietary intake each day during a "Run-In Week.". Eligible participants will then receive an 8-week weight loss program, including individual weekly sessions with health coaches. The investigators will also ask participants to complete both a baseline and follow-up session with study staff. If permitted by current university policies, these sessions will be held at the offices on Northwestern University's Chicago campus. Otherwise, these sessions will be conducted remotely via Zoom videoconference. If this is the case, as a privacy safeguard, the waiting room feature will be applied so that study staff can control who is admitted into the meeting. We expect that the participants will be in this research study for about 10 weeks.

The primary risk of participation is muscle soreness or injury from increased physical activity, as well as feelings of hunger from making changes to diet. The main benefit is that a participant may experience positive changes to their health and mood based on the study.

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Single Behavioral Arm; Everyone in the study will receive the same type of treatment. They will all receive a treatment period that will last for 8 weeks. All participants will be given a 3% total weight loss goal, a daily calorie goal ranging from 1200-2000 kcal/day based on body weight, and a daily fat goal based on 25% of total daily calories from fat, and an option to stop their food/energy intake at 6pm every day without altering any other meal times. .Participants will also be asked to use two meal replacements per day. Participants will also be given a physical activity goal of 100 minutes per week.

Behavioral: Interventional Behavioral Arm; All participants will receive a weight loss intervention that includes 8 coaching sessions guided by a workbook they will at their baseline visit. During these sessions, they will meet with a health coach individually for up to 10-15 minutes via telephone or video conference to learn and discuss weight loss strategies. Health coaches will provide feedback and instruction (by phone or email) based on progress and challenges encountered during the intervention. Participants will receive a weight management app custom-built for the research study. The app will display participants' dietary intake, physical activity, and weight data and goals on the smartphone, and participants will use the app to log dietary intake, physical activity, and weight daily.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Primary Outcome - Weight - Aria Scale	Weight will be measured in the lab at baseline and then the change in weight at the follow-up. Baseline measurements occur one week before the study and follow up measurements occur at week 8 of the study. Measurements will be taken without shoes, wearing light clothing on a calibrated beam balance scale called the Aria Scale. For melanoma patients only, skin self-examination frequency will also be assessed.	Baseline (week one) & Follow Up (week 8)

Secondary Outcome Measures

Additional Physiologic Outcomes	Height will also be measured using a stadiometer.	Baseline (week one) & Follow Up (week 8)
