Possible variances of blood urea nitrogen, serum potassium and phosphorus levels and interdialytic weight gain accounted for compliance of hemodialysis patients.
OBJECTIVE
The aim of this study was to assess the possible variances of blood urea nitrogen (BUN), serum potassium (SK) and serum phosphorus (SPO(4)) levels and interdialytic weight gain (IWG) accounted for compliance of uremic patients on hemodialysis (HD).


METHODS
BUN, SK and SPO(4) levels and IWG of uremic patients (n=310) regularly undergoing three HD sessions per week for more than 1 year in Japan were assessed. Patients suffering from problems influencing dietary intake and those with malnutrition were excluded. The variances accounted for self-efficacy for health-related behavior and avoidance-oriented coping (AOC) with stress were assessed by hierarchical multiple regression analyses.


RESULTS
BUN and SPO(4) levels were not significantly (P<.05) associated with self-efficacy or AOC. SK levels and IWG were significantly (P<.05) associated with self-efficacy and/or AOC. The variances of SK levels and IWG accounted for self-efficacy and/or AOC, independent of age, sex, duration of HD and facilities, were 1.6% and 5.0%, respectively.


CONCLUSIONS
Although the variances of SK levels and IWG accounted for self-efficacy and/or AOC were rather small, the significance of their relationships may suggest that intervention for self-efficacy or AOC could improve compliance and reduce SK levels and IWG of uremic patients on HD.
