Asthma treatment adherence among asthmatic patients in Yazd

Background Asthma affects an estimated 300 million people worldwide. Poor compliance with prescribed medication leads to increased morbidity and mortality. The number of asthma cases has more than doubled since 1980 and, nearly 3 million workdays are lost annually due to asthma exacerbations. Non-compliance with therapy is a major impediment to effective asthma management and can lead to failure of treatment. The purpose of the study was to identify the better predictor for adherence behaviors between knowledge of asthma, health beliefs, attitude toward the illness of asthma, and behavioral intention to adhere.
