Background
Stroke is a leading cause of death and disability-adjusted life years globally. The incidence of stroke is increasing in Asia, with ischemic stroke accounting for approximately 80% of stroke cases in Thailand. Stroke often results in long-term disabilities, including impairments in speech, communication, and concentration.
Objective
This study aimed to investigate factors associated with newly diagnosed ischemic stroke.
Methods
A matched case-control study was conducted, including 154 newly diagnosed ischemic stroke cases and 183 non-stroke individuals with type 2 diabetes mellitus (T2DM) as controls. Data were collected between February and September 2022 (post-COVID-19 period) using a structured questionnaire covering (1) socio-demographics, (2) lifestyle factors, (3) perceived social support, and (4) self-care management (SCM). Multivariable logistic regression models were employed to calculate adjusted odds ratios (aOR) with 95% confidence intervals (CI).
Results
Most participants were female (60.8%), Buddhists (92.9%), and agriculturists (66.5%), with a mean age of 58.9 (±9.9) years. Factors associated with ischemic stroke included male sex (aOR=3.533, 95%CI 1.732–7.206), Buddhism (aOR=3.529, 95%CI 1.107–11.250), sedentary occupation (aOR=5.785, 95%CI 2.613–12.807), and having T2DM for over 10 years (aOR=6.194, 95%CI 3.553–10.798). Protective factors included age ≥ 60 years (aOR=0.553, 95%CI 0.312–0.982) and moderate SCM levels (aOR=0.453, 95%CI 0.256–0.802).
Conclusion
Prolonged T2DM and sedentary occupations significantly contribute to ischemic stroke incidence. Effective prevention programs, including lifestyle modifications and diabetes self-care management education, may help reduce the burden of ischemic stroke.
