Methods: A total of 1116 newly diagnosed adult asthmatic patients from 122 secondary or tertiary centers of different geographic locations took part in the study, and a standard web-based questionnaire was applied from July-2012 to March-2014. Patients were divided into two groups as YA (age: 18-59) and EA (age≥60). The differences in biometric parameters, pulmonary functions, allergic status, comorbidities, first given therapies, one year control, and adherence to treatment were analyzed.
Results: The age of 12.2% of the new-onset asthma patients was ≥60 years. Body mass index was found as 27.8 kg/m2 for YA and 29.8 kg/m2 for EA (p<0.001). The presence of any comorbidity was 66.2% and 52.2% in EA and YA, respectively (p=0.003). Combined inhaled steroid plus long acting beta2 agonists were the most frequently administered treatment (83.0% vs. 93.4% in YA and EA, p=0.002).
The asthma control during one year was not significant between groups. But the number of visits were elevated in EA than YA (1.60 vs 1.22, p=0.011). The adherence to therapy was not significant between groups. The adherence to therapy in EA was significantly correlated with the presence of hypertension (p< 0.025).
Conclusions: Our findings demonstrated that EA presented more co-morbidities and the presence of hypertension increased adherence to asthma treatment in elderly asthmatics.
