Chang TI, et al. - This study aimed at assessing the association of body weight changes with mortality in incident hemodialysis patients. Results revealed a decline in post-dialysis weight and it reached a nadir at the 5th month, in patients who survived the first year of hemodialysis. An association was observed between an incrementally larger weight loss during the first 12 months and higher death risk. On the other hand, weight gain was associated with greater survival during the 5th to 12th month but not in the first 5 months of dialysis therapy.
