Brief 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.

Study Arms (2)

Standard Care

ACTIVE COMPARATOR

Participants randomly assigned to this arm will receive standardized weight management educational materials plus a monetary gift of $60 that can be used to purchase health-promoting supplies to support weight management.

Behavioral: Standard Care

Daily Self-Weighing

EXPERIMENTAL

Participants randomly assigned to this arm will receive standardized weight management educational materials plus a commercially available wireless scale. Participants will be instructed to weigh daily and view their weight on the scale's digital display.

Behavioral: Daily Self-Weighing

Interventions

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.

Daily Self-Weighing
Standard CareBEHAVIORAL

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.

Eligibility Criteria

Age19 Years - 65 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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

You may not qualify if:

  • 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.

Data Sharing

IPD Sharing
Will share

The PI will ensure all publications that result from project-related data will comply with the NIH public access policy and develop a system by which study data may be shared with other investigators within the scientific community. With UAB IRB permission, PI may develop a de-identified database, codebook, and mechanism by which data can be shared with qualified individuals/organizations. PI will keep a record of all individuals/res. teams who request/receive a copy of the data. Interested investigators will be asked to complete a request form stating specific aims of the analyses, analytic plan, available resources, proposed timeline, and goals. PI and team will review these requests to determine whether proposed analyses constitute significant exploration of the data, team has resources to complete request, and data will be adequately protected and managed. If any issues are problematic, PI and team will attempt to negotiate a fair resolution with investigators and NIH staff.
