title: Body-weight change and physical functioning among young old adults.
abstract: OBJECTIVE
  The main purpose of this study is to examine if body weight change is a potential risk factor for the onset of functional impairment across time among various functional domains.
  
  
  METHODS
  Using longitudinal data from the Health and Retirement Study, logistic regression models on the onset of functional impairment over three time points are estimated for young old adults.
  
  
  RESULTS
  Results indicate that weight gain is associated with greater risk of lower body mobility impairment. An increase in body mass index of greater than 5% increases the likelihood of the onset of lower body mobility functional impairment.
  
  
  CONCLUSIONS
  Study findings support the promotion of healthy weight management. Future studies in this area may want to investigate effective interventions that contribute to healthy weight maintenance among this cohort.
