Health-related quality of life and socioeconomic status : inequalities among adults in west of Iran

Abstract EN

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 46.329.69 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.
