        We conducted a descriptive, comparison study to examine type, amount of comorbidity, and multimorbidity among five age group, and between older adults versus adult with transient ischemic attack (TIA). We used secondary data from the stroke registry of the total 157 TIA patients who were admitted to a 750-bed tertiary care hospital, between December 2011 and September 2015. Ten comorbidities were documented including hypertension, diabetes mellitus, hypercholesterolemia, atrial fibrillation or atrial flutter, coronary heart disease, heart failure, peripheral artery disease, previous history of transient ischemic attack or ischemic stroke, smoking, and alcohol drinking. Multimorbidity was defined as the presence of two or more comorbidities. Bivariate logistic regression was performed to test whether aged-related differences in comorbidity, and multimorbidity. 

        Univariate unadjusted model reveled that middle-aged elderly had less prevalence of smoking (OR 0.23; 95%CI 0.06-0.88), alcohol drinking (OR 0.13; 95%CI 0.06-0.88), and the multimorbidy of smoking and alcohol drinking (OR 0.18; 95%CI 0.04-0.81), compared with young adult. The elderly group had less prevalence of smoking (OR 0.23; 95%CI 0.06-0.88), alcohol drinking (OR 0.13; 95%CI 0.03-0.59), hypertension and smoking (OR 0.38; 95%CI 0.17-0.88), and smoking and alcohol drinking (OR 0.47; 95%CI 0.24-0.94), but higher prevalence of hypercholesterolemia (OR 2.08; 95%CI 1.00-4.33), compared with adult. Only smoking was associated with aged after sex-adjusted, the elderly had 64% less smokers (OR 0.36; 95%CI 0.15-0.89) compared with adult.

        This study suggested that reguarding differences of aged-related comorbidity, and multimorbidity among TIA patients was complex and uncertain. An assessment of aged-specific multimorbidity is a clinical meaningful data in order to provide specific risk reduction and target to specific age group.
