• Description:
  Objectives
  
  Examine bi-directional associations between weight perception and weight change over time among adults.
  
  Methods
  
  Data are from adult employees (N=623) across 12 U.S. public high schools participating in a cluster-randomized multilevel weight gain prevention intervention. Data were collected at baseline, 12 months, and 24 months. Perceived weight status (very/somewhat underweight, just right, somewhat overweight, very overweight) were obtained via self-administered surveys. Weight (kg) was measured by trained staff. Change in weight was calculated as the difference between baseline weight and weight at each follow-up timepoint. Structural equation models were used to assess bi-directional associations of perceived weight status and change in weight over time. Models adjusted for study condition, gender, age, race/ethnicity, education level and previous timepoint.
  
  Results
  
  The sample was 65% female with a mean age of 44.6 (SD=11.3). Nearly two thirds of the sample consisted of people with overweight (38.8%) or obesity (27.3%). Structural equation models indicated that baseline weight predicted subsequent perceived weight status (β=.26; p<.001), whereas baseline perceived weight status did not predict subsequent change in weight, adjusting for previous timepoint and covariates.
  
  Conclusions
  
  Results do not support bi-directional causality between weight perception and weight change in an adult sample.
