Overall health related quality of life and relative differences between men and women and also between different age groups (60-75 years vs. >75 years) was assessed in this study. A total of 1000 elderly individuals completed the SF-36 questionnaire. Of all participants 499 (49.9%) were men, 501(50.01%) women, 789 (78.9%) aged 60-75 years, and 211 (21.1) aged over 75 years. The logistic regression analysis showed the age over 75 years could increase the risk of lower score of physical [OR: 2.69, CI; (1.96-3.73] and mental [OR: 1.58, CI (1.16-2.15)] component summaries of SF-36 regardless other factors. Additionally, suffering from chronic diseases could decrease physical and mental scores of health related quality of life separately [OR: 8.6, CI; (4.37-16.94) and OR: 1.8, CI (1.1-2.99) respectively]. Women compared to men and illiterate old people compared to literate ones are more likely to perceive worse health related quality of life especially in physical component [OR: 1.35, CI; (1.01-1.81) and OR: 1.59, CI (1.12-2.24) respectively ].
