Application of the short form of quality of life instrument version 2 in a large population of Tehran

Abstract

Background: Quality of life (QoL) is now considered as a key indicator in health studies. Therefore, this study was conducted to evaluate QoL in the general population of Tehran (capital of Iran) using SF-12v2 questionnaire and determine some factors associated with it. Methods: This was part of a large population-based cross sectional study conducted in Tehran, Iran, in 2011. Participants were selected from all districts of Tehran using multistage cluster random sampling method. Data were collected using the Iranian version of the SF12v2 questionnaire. Linear regression model was used to assess the independent effect of surveyed variables of the study population on their QoL. P< 0.05 was considered statistically significant. Results: Overall, 30 809 individuals over the age of 20 from 22 urban districts were included in this study and evaluated by SF-12v2 questionnaire. The mean age of the study population was 44.5±15.9, and most of them were female (19 967 (64.8%)). The total mean score of SF-12v2 was 60.4 and the lowest and highest mean scores were observed in GH (46.9±26.5) and MH subscales (64.1±24.7), respectively. It was also observed that District 3 of Tehran had the highest mean score (65.2±18.7) in the total QoL and District 12 had the lowest mean score (56.6±18.7), respectively. The results of multiple linear regression model showed that sex, age, education, household size, presence of chronic disease in family, having insurance, smoking, and marital status were significantly related to most subscales and two summary components of QoL. Conclusion: The results of this study showed that the surveyed population of Tehran had a relatively moderate QoL, but it changed from district to district. It was also observed that age and education of the study population were important variables in relation to QoL.

Factors Associated with Health-Related Quality of Life among Government Employees in Putrajaya, Malaysia

“…On the other hand, a significant association between sex and HRQOL was limited to the health domains of BP and GH. This finding is consistent with previous studies that also agreed that being female was associated with poor BP and GH [ 41 ]. Working females invested more energy and faced high strain in order to cope with noticeable demanding roles, namely, responsibilities within the home and managing tasks at the workplace [ 42 ].…”

“…Therefore, these situations eventually affect certain joys of life, particularly physical, psychological, and social well-being. Moreover, the findings in this study are in line with past studies that mention that a family history of chronic disease is significantly associated with poor mental health [ 41 ]. Family history has been a known risk factor of developing several chronic diseases since it reflects inherited genetic susceptibility as well as shared behaviour and environment among family members [ 47 ].…”

Validity and reliability of the Persian version of the oropharyngeal Mucositis quality of life scale

“…A study showed that treatment of chemo-radiotherapy induced oral mucositis due to lung and head, and neck cancer possess over 17,000$ (USD) incremental cost per patient [ 7 ]. So for the evaluation outcome of patients with oral mucositis to reflect the full impact of oral condition, assessment of the quality of life as a critical health-related indicator, besides the biomedical parameters is necessary [ 8 , 9 ]. The definition of quality of life, according to the World Health Organization is “an individual’s perception of their position in life in the context of the culture, and value systems in which they live, and in relation to their goals, expectations, standards, and concerns” [ 10 ].…”
