Daily Self-Weighing for Obesity Management in Primary Care

Not Applicable

Active, not recruiting

• Conditions: Overweight and Obesity
• Interventions: Behavioral: Standard Care; Behavioral: Daily Self-Weighing

• Registration Number: NCT04044794
• Lead Sponsor: University of Alabama at Birmingham

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.

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.

Arm && Interventions

Group	Intervention	Description
Standard Care	Standard Care	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.
Daily Self-Weighing	Daily Self-Weighing	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.

Primary Outcome Measures

Name	Time	Method
Change in body weight from baseline to month 18	18 months	Body weight measured to the nearest 0.1 kg using a calibrated electronic scale
Change in body weight from baseline to month 6	6 months	Body weight measured to the nearest 0.1 kg using a calibrated electronic scale
Change in body weight from baseline to month 12	12 months	Body weight measured to the nearest 0.1 kg using a calibrated electronic scale
Change in body weight from baseline to month 24	24 months	Body weight measured to the nearest 0.1 kg using a calibrated electronic scale

Secondary Outcome Measures

Name	Time	Method
Average number of weight control behaviors endorsed on the Weight Control Practices Survey at month 24	month 18 to month 24	A modified version of the 23-item Weight Control Practices Survey will assess a variety of strategies for weight control, including participation in structured programs and/or self-directed weight control behaviors (e.g., reducing fat intake, maintaining food records, increasing physical activity, frequency of self-weighing). The survey measures presence and duration (in weeks) of each behavior.
Average number of weight control behaviors endorsed on the Weight Control Practices Survey at month 12	month 6 to month 12	A modified version of the 23-item Weight Control Practices Survey will assess a variety of strategies for weight control, including participation in structured programs and/or self-directed weight control behaviors (e.g., reducing fat intake, maintaining food records, increasing physical activity, frequency of self-weighing). The survey measures presence and duration (in weeks) of each behavior.
Average number of weight control behaviors endorsed on the Weight Control Practices Survey at month 6	baseline to month 6	A modified version of the 23-item Weight Control Practices Survey will assess a variety of strategies for weight control, including participation in structured programs and/or self-directed weight control behaviors (e.g., reducing fat intake, maintaining food records, increasing physical activity, frequency of self-weighing).
