81 Changes in determinants of health-related behavior over time PART 1 Table 1: Baseline characteristics ( N=100) Health related behavior Smoking, n(%) 36 (36) Alcohol abuse, n (%) 5 (5.2) Physical exercise 5 (min/day), median (IQ) 129.6 (60-218.6) Physical exercise > 30 min a day n (%) 75 (87) Overall dietscore 6 , median (IQ) scores from -17 to +19 1.0 (-2-2.5) BMI (kg/m 2 ), mean (SD) 26,5 (3.6) Overweight (BMI>25), n(%) 64 (64) 1 Classification of subtype of acute ischemic stroke developed for the Trial of Org 10172 in Acute Stroke Treatment (TOAST). 2 Quantification of stroke severity according to the National Institutes of Health stroke scale (NIHSS), a 15- item scale with scores that range from 0 to 42 and higher values indicating greater severity. 3 Assessed with the Minimal Mental State Examination and Montreal Cognitive assessment (MoCA). 4 Scored with the Centre for Epidemiologic Studies Depression Scale (CES-D) 5 Measured with the International Physical Activity Questionnaire short (IPAQ-S) questionnaire. 6 Evaluated with the short Food Frequency Questionnaire (FFQ). The higher the score, the more favorable the dietary pattern.
