Clinical Trial Summary

Many adults with obesity continue to gain weight even though they do not want to. This project will test the effects of a primary care intervention in which people with obesity receive an electronic scale and recommendations to weigh themselves daily. This will help us understand whether daily self-weighing might be a way to prevent continued weight gain.

Recruitment information / eligibility

• Status: Active, not recruiting
• Enrollment: 396
• Est. completion date: March 2025
• Est. primary completion date: March 2025
• Accepts healthy volunteers: Accepts Healthy Volunteers
• Gender: All
• Age group: 19 Years to 65 Years

Eligibility

Inclusion Criteria:

• Age 19-65 years

• Body mass index (BMI) 30 - 50 kg/m2

• Receives care at one of the participating primary care clinics

• Resides in one location at least 5 days each week

• Possesses a smartphone with data plan

• Wi-Fi or Bluetooth internet connection in home

Exclusion Criteria:

• Pregnancy or anticipating pregnancy during study duration. This is a weight loss study and weight gain/loss due to pregnancy and/or delivery would confound study results. Additionally, weight loss is not recommended for pregnant women.

• Unwilling or unable to do any of the following: give informed consent, accept random assignment, attend five measurement assessments

• Likely to relocate and no longer be seen at UAB primary care in the next 2 years

• Weight loss =5% of body weight in past 6 months (other than postpartum)

• Weight >180 kg (396lbs) due to the limitation of the scale being used.

• Current participation in another weight loss study

• Bariatric surgery or revision in the past two years

• Prescription weight loss medications within the past 6 months

• Another household member already participating in the study

• Potential participants living farther than 50 miles driving distance from UAB will be excluded from the study. It is expected that those living farther away will be more difficult to retain as study participants.

Intervention

Behavioral:
• Standard Care
Standard care includes standardized educational materials to promote self-management of body weight along with provision of $60 for participants to purchase supplies or equipment to facilitate weight management.
• Daily Self-Weighing
Participants will receive a wireless digital scale and will be asked to keep the scale in their home, weigh daily at the same time, and view their weight trajectory on the scale's digital display.
