PURPOSE: Patients with diabetes mellitus (DM) has been found to have increase risk cardiovascular disease and possible pulmonary hypertension The goal of this study was to evaluate the prevalence of asthma in patients with type II DM after adjusting for other co-morbid conditions.
METHODS: We used patient treatment files of inpatients’ admissions containing discharge diagnosis (ICD-9 codes) from Veterans Health Administration Hospitals. The patients were divided in two groups: ICD-9 code for DM (293,124) and a control group with hypertension (HTN) but no DM (552,623). ICD-9 codes for with ICD-code for asthma (493.9, 493.1) were used to study prevalence of these diseases in DM patients vs the control. We performed uni- and multi-variant analysis adjusting for CAD, CHF, hyperlipidemia, pulmonary hypertension, pulmonary embolism and smoking.
RESULTS: Asthma was present in 13,242 (4.5%) of DM patients vs. 16,038 (2.9%) in the control group. Using multivariate analysis, DM remained independently associated with asthma (OR: 2.99; CI: 2.92 to 3.06; p<0.0001).
CONCLUSION: The prevalence of asthma is significantly higher in patients with DM independent of other co-morbid conditions.
CLINICAL IMPLICATIONS: The diagnosis of asthma should be considered in diabetes patient presenting with respiratory symptoms.
