title: Body fat mass in hemodialysis patients.
abstract: BACKGROUND
  Changes in body fat mass in a large number of hemodialysis patients is unknown.
  
  
  METHODS
  Body fat mass and lean body mass were measured by dual x-ray absorptiometry (DXA) in 561 patients with hemodialysis duration less than 180 months (62.3 +/- 11.5 years old; mean +/- SD).
  
  
  RESULTS
  Fat mass tended to increase during the first 3 years of hemodialysis, and it tended to decrease thereafter. Between hemodialysis duration and the fat mass index, there was a significant positive correlation within the first 36-month period of hemodialysis (r = 0.124; P < 0.05; n = 245), and a significant negative correlation during the period of 36 to 180 months. (r = -0.192; P < 0.001; n = 316). There was no tendency of change in the lean body mass index.
  
  
  CONCLUSIONS
  Considering the results together with the authors previous prospective study results, which show significant fat mass increase in the first year of hemodialysis, the present cross-sectional study may suggest that fat mass gradually increases in the first 3 years and decreases thereafter. Fat mass is suggested to be a nutritional parameter in hemodialysis patients.
