Objectives: To estimate the incidence of diabetes, acute myocardial infarction (AMI), and stroke; and to determine factors associated with diabetes, AMI, and stroke incidence among patients previously treated for tuberculosis (TB) disease.
Methods: A retrospective cohort study was conducted among non-pediatric TB patients registered in the Taiwan National Health Insurance Research Database (NHIRD) from 2002-2013. Diabetes, AMI, and stroke incidence were defined by International Classification of Diseases (ICD)-9 codes, drug prescriptions, and records of patient's clinic visits. Cox proportional hazard models were used to estimate the hazard rate ratio (HR) of incident diabetes, AMI, and stroke.
Results: From 2002-2013, there were 157,444 patients treated for TB registered in NHIRD. Among 129,453 patients with no prior history of diabetes, the age-adjusted incidence rate (IR) of diabetes was 3.85 (95%CI 3.70-4.01) per 1000 person-years. Among 143,646 patients with no prior history of AMI, the age-adjusted IR of AMI as 3.26 (95%CI 3.13-3.40). Among 118,774 patients with no prior history of stroke, the age-adjusted IR of stroke was 16.08 (95%CI 15.76-16.32).
Conclusions: Chronic non-communicable disease risk factors like dyslipidemia, hypertension, and chronic kidney disease diagnosed before time of TB diagnosis were predictive of diabetes, AMI, and stroke incidence.
