Health-related quality of life of patients with asthma: a cross-sectional study in Semnan, Islamic Republic of Iran.

Asthma can profoundly affect the quality of life of individuals with the disease. There are limited data on the quality of life of people with asthma in the Islamic Republic of Iran. This cross-sectional study aimed to evaluate quality of life in adults with asthma in Semnan using the 36-item short form health survey (SF-36). The effect of sociodemographic characteristics on quality of life scores was examined. The study included a convenience sample of 385 outpatients with asthma attending a pulmonary clinic from June to December 2013. The mean physical and mental component scores were 58.8 (SD 18.3) and 57.3 (SD 17.0) respectively. The study sample had lower quality of life scores in all the fields than the reference population (P < 0.05). Patients with lower education, urban residents, widowed/divorced patients and manual workers had lower quality of life scores (P < 0.05). Efforts are needed to improve the quality of life of people with asthma in parallel with precise management plans.
