Scientific Questions Being Studied

Numerous studies have reported that losing as little as 5% of one’s total body weight (TBW) can improve health. We have previously used UW electronic health record (EHR) data to examine long-term changes in weight and found that adults with severe obesity were more likely to lose at least 5% TBW compared to overweight patients and patients with class 1 obesity. However, sufficient weight loss to obtain a non-obese weight class was rare. The median weight change for the population was a net gain of 2.5% TBW.

Objective: To measure long-term weight changes and examine their predictors for adults in a large academic healthcare system

Project Purpose(s)

  • Methods Development

Scientific Approaches

Measures: Over a 5-year period: 1)  5% total body weight (TBW) loss; 2) weight loss into a non-obese BMI category (BMI < 30 kg/m2); 3) ≥10% TBW gain; and 4) predictors of %TBW change via quantile regression.

Anticipated Findings

We anticipate that the All of Us data will help us validate the findings from our prior research using the UW EHR data.

Demographic Categories of Interest

This study will not center on underrepresented populations.
