Health-Related Quality of Life and Socioeconomic Status: Inequalitiesamong Adults inWest of Iran
2017
Background: Socioeconomic status (SES) is one of the main determinants of health-related quality of life (HRQoL), where people
with lower SES experience more health problems, have a lower quality of life, and are exposed to have a greater number of healthrelated
risk factors.
Objectives: This study aimed to examine the relationships between HRQoL, SES, and several demographic factors among the residents
of the city of Ilam (located at theWest of Iran).
Methods: This cross sectional study was conducted on 400 households from 3 districts of the city of Ilam in 2015. The participants
were selected on the basis of the multistage sampling method. The second version of the 12-item Short-Form Health Survey (SF-12v2)
questionnaire and theWealth Index were used to measure HRQoL and SES, respectively.
Results: The mean scores of the physical component summary (PCS) and the mental component summary (MCS) were 46.32�9.69
and 42.12 � 9.11, respectively. The findings indicated that PCS (P = 0.01) and MCS (P = 0.01) were significantly related to SES (wealth
index). The demographic variables of age, gender, education level, marital status, job status, and home ownership (P < 0.05) were
also significantly related to both PCS and MCS.
Conclusions: HRQoL is directly related to SES, in that HRQoL is higher in families with higher SES. Similarly, HRQL is higher in
younger people, men, and those with a university degree. A decrease in socio-economic inequalities and the gap between the rich
and the poor can enhance the individuals’ health status and HRQoL within a community.
