title: Promoting changes in obesogenic behaviors: does coworker social support play a role?
abstract: OBJECTIVE
  To examine the association between worksite social support and changes in diet, physical activity, and body mass index (BMI).
  
  
  METHODS
  Cohort analysis of an underlying randomized, controlled weight gain prevention worksite trial: Promoting Activity and Changes in Eating.
  
  
  METHODS
  The trial occurred in the greater Seattle area.
  
  
  METHODS
  Baseline and follow-up data were obtained on a nested cohort of employees (n = 958-1078) from 33 small- to medium-sized worksites.
  
  
  METHODS
  Worksite social support, diet, physical activity, and BMI measures were assessed using a self-reported questionnaire.
  
  
  METHODS
  To adjust for multilevel data and multiple time points, we used generalized estimating equations and logistic mixed models.
  
  
  RESULTS
  Higher baseline worksite social support was associated with greater changes in fruit and vegetable intake (p = .001; summary food-frequency questions).
  
  
  CONCLUSIONS
  This study does not support a conclusive relationship between worksite social support and health behavior change.
