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 SF-12v2 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.
