The  Quality of  Life (QOL)  of  sufferers with AR is significantly affected. The aim of this study was to evaluate the QOL of adults with AR. This study was designed for adults with AR above 18 years old. The study was conducted using a valid Rhinitis Quality of Life Questionnaires (RQLQ) which was completed for each patient during clinic visit and analyzed by applying statistical methods. One-hundred  and ten AR patients participated in this study. Mean age of these patients was 32 years old and 62% were female. The   correlation  between  severity  of   AR  and  QOL   impairment  was  significant. Frequencies of mild persistent, moderate-severe persistent, mild intermittent and moderate- severe intermittent types of AR were 18%, 34.5%, 9% and 38%, respectively. Completed RQLQ indicated that about 55% of the cases were suffering from severe disturbances in their  QOL.   Furthermore,   congestion  (88%)  was  the  most  common   symptom.  The correlation between congestion and QOL reduction was significant. The correlation between congestion and sleep impairment was significant. AR was more common in young as well as female patients and their QOL  was affected more than the others. The results showed a good relevancy between severity of symptoms and QOL scores. Consisting with ARIA classification, it was found that reduction in the quality of life is higher in patients with moderate-severe intermittent and persistent asthma. Nasal congestion was a bothersome and prevalent symptom in AR that was responsible for sleep problems. Therefore, nasal congestion was associated with sleep-disordered breathing, nocturnal sleep impairment, day time fatigue and somnolence which finally lead to QOL impairment. https://ijaai.tums.ac.ir/index.php/ijaai/article/view/545 https://ijaai.tums.ac.ir/index.php/ijaai/article/download/545/505
