Abstract W P128: The Effect of Obesity on K-Modified Barthel Index at 6 Months after Stroke: A Prospective Multicenter Study
Introduction: Previously, association between body mass index (BMI) and K-Modified Barthel Index (KMBI) score was reported. However, few studies investigated the value of obesity as a predictive factor of 6 months functional outcome after stroke.
Aims: The aim of this study is to examine whether BMI predicts the 6-month KMBI after stroke onset with adjustment for cardiovascular disease risk factors socioeconomic position and health behavior factors in stroke patients.
Methods: This is an interim report of the Korean Stroke Cohort for Functioning and Rehabilitation (KosCo). The sample included 1,299 stroke patients, both ischemic and hemorrhagic, aged 18-92 years. FIM score was assessed at 6 months after stroke onset. Subjects were classified into three groups based on their baseline BMI categories at admission: normal (18.5 ≤ BMI < 23), overweight (23 ≤ BMI < 25), or obese (BMI ≥ 25) groups.
Results: The mean age was 64.1 (±12.8) years. The distribution of overweight and obese groups was 28.5 % and 36.3 %, respectively. The mean 6-month KMBI was 85.6 (±27.6) and 88.0 (±26.0), respectively. The 6-month KMBI significantly increased in obese group compared to the normal BMI group after adjustment for confounding factors. In the ischemic stroke, the 6-month KMBI was increased in the obese group (p<0.05), but not in the hemorrhagic stroke.
Conclusions: This hospital-based cohort study showed that obesity measured by BMI may predict good 6 months functional outcome, especially, for the ischemic stroke patients (Supported by Korea Centers for Disease Control and Prevention (2013E3301701)).
