Abstract

Purpose: The aim of this study was to assess whether BMI can predict the six-month-length prognosis of stroke using Unified Neurological Stroke Scale(UNSS) as the outcome measure.

Methods: A group of 116 ischemic stroke patients admitted to the neurology ward of Razi University Hospital in Tabriz were enrolled into a prospective study. Body mass index(BMI) was measured at admission to hospital and its correlation with the change in UNSS score over six months after stroke was assessed.

Results: Out of the 100 patients studied, 70% were males. Mean(SD) weight of the patients was 72.4(10.9) Kgs. Mean(SD) height of the participants was 1.64(0.09) meters. Mean (SD) of body mass index(BMI) was 26.8(3.27) Kg/m2. Mean change in UNSS score from admission time to a follow-up time after six months was 9.28 with a standard deviation of 4.98. In assessing the correlation between BMI and stroke prognosis, Pearson's correlation coefficient was calculated to be -0.58 between the change in UNSS score over the study period and BMI(p<0.001).

Conclusion: BMI irrespective of its role in increasing the likelihood of stroke incidence could also predict its prognosis.
