Abstract T P142: Mortality and Stroke Recurrence in Obese Stroke Patients: The Obesity Paradox in a London-Based Population

INTRODUCTION Several studies have shown a paradoxical association between body mass index (BMI) and mortality after stroke. However, the association between BMI, waist circumference (WC) and mortality and stroke recurrence is unclear. This study aimed to determine the associations between BMI, WC and mortality and stroke recurrence at 6 months post stroke. METHODS Patients were recruited from consecutive admissions at 2 hyper-acute stroke units in London and were classified into 4 categories of BMI (underweight, normal weight, overweight and obese) and quartiles of WC. Outcomes were obtained for each patient through a national database that contains details of all hospital admissions. Chi-square tests were used to compare mortality and stroke recurrence rates. Cox Proportional Hazards Models were used to compare mortality risk and survival curves between different BMI categories and WC quartiles. RESULTS Of 543 recruited patients, 51% were males and 87% had an ischaemic stroke, with a mean age of 74.7 yea...
