Health-Related Quality of Life in a Sample of Iranian
Patients on Hemodialysis
Introduction. This study evaluated the health-related quality of life
(HRQOL) in a sample of Iranian patients undergoing maintenance
hemodialysis. The data were compared with the HRQOL for the
Iranian general population.
Materials and Methods. Two-hundred and fifty patients undergoing
hemodialysis were included using a convenience sampling approach
in a cross-sectional study. Data collection was performed using a
Persian translation of the Short Form-36 questionnaire in combination
with demographic and clinically related questions. The collected
data were analyzed using a logistic regression model with physical
and mental summary scales as dependent variables.
Results. The Cronbach α coefficients used to test for internally consistent reliability for each scale. In every case, the scales were found to have an acceptable reliability, as indicated by the measured values, which either met or exceeded 0.7, as recommended. The percentage of respondents scoring close to or at the upper
limit (ceiling effect) was considerable for each of the scales. The patients’ mean Short Form-36 scores were significantly lower than those obtained for the general population for all scales. Patients with longer duration of being on hemodialysis, poor
adherence to treatment, higher body mass index, and comorbidity diseases suffered from a poorer physical health. Poor mental health was associated with a lower level of education, longer duration of hemodialysis, lower economic status, a lower degree of knowledge on disease, and comorbidity diseases.
Conclusions. This study affirms the fact that patients undergoing
hemodialysis suffer from poor HRQOL. In comparison with data
from other studies from Asian and European countries, this sample of
Iranian patients on hemodialysis had a lower HRQOL, a discrepancy
that might be due to differences in life style, socioeconomic status,
the general level of education of the patients, as well as physicianpatient
quality of life,
