Background:  Few literatures mentioned about the difference between absolute interdialytic weight gain (IDWG) and IDWG/DW (IDWG%), and subsequent effects on daily dialysis. The aim of present study was to evaluate the different between absolute IDWG and IDWG% in new hemodialysis patients. Method:  We retrospective reviewed the records of 255 patients who recently received conventional hemodialysis for at least 1 year at the same center from 1997 to 2008. The first 4 weeks after starting hemodialysis was defined as the pre-study period. Data were collected for 5-56 weeks. Results:  IDWG% value remained relatively constant in the first year of hemodialysis despite most patients had certain residual renal function. For hemodialysis outcomes, both absolute IDWG and IDWG% were significantly correlated with intradialytic hypotension (IDH) in men and heavy women. After divided patients into 4 stratums which according to the gender and the median dry weight, stepwise multivariate linear regression analysis showed that absolute IDWG, rather than IDWG%, was an independent risk factor for IDH in heavy men (Beta = 0.585, p < 0.001) and heavy women (Beta = 0.458, p < 0.001). Conclusions  Absolute IDWG, rather than IDWG%, is an independent risk factor for IDH in heavy hemodialysis patient. Therefore, higher absolute IDWG remain need to be strict controlled despite the corresponding IDWG% might be relative small in heavy hemodialysis patients.
