Purpose. The aim of this study was to assess the relationships of compliance with age, sex, and duration of hemodialysis (HD) simultaneously in a large population of uremic patients on HD. Methods. Uremic patients (n = 484) who were regularly undergoing 3 HD sessions/week in Japan were investigated with regard to age, sex, duration of HD, and compliance measures (i.e., blood urea nitrogen [BUN], serum potassium [SK], and serum phosphorus levels [SPO4] levels and interdialytic weight gain [IDWG]). Associations and interactions among them were assessed by correlations and hierarchical multiple regression analyses. Results. Older age was significantly associated with low levels of BUN, SPO4, and IDWG (p<0.05), but not with SK levels. Longer duration of HD was significantly associated with high levels of SK, SPO4, and IDWG (p<0.05), but not with BUN levels. The regression lines illustrating significant (p<0.05) interactions predict that in men, the longer the duration of HD, the higher the levels of BUN and SK, and the higher the IDWG; this was not the case in women. Conclusions. In uremic patients on HD, compliance was likely to be different based on the patient's sex and duration of HD.
