There were indirect significant correlations between total score of QOL and its all sub-domains with beck depression score but direct significant correlations with total physical activity (p<۰.۰۵) except for social relationship. Educational stage, employment status, family income, inhabitant, moderate physical activity, and depression were predictors of QOL and altogether explained ۶۳% of its variance.
