title: Is malnutrition a risk factor of stroke?
abstract: Obesity is an established risk factor of stroke. Malnutrition in post-stroke period is common and can influence outcome. But malnutrition, though predicted, has not yet been established as a risk factor of stroke. This descriptive study was carried out in the Department of Neurology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka and Department of Neurology, Dhaka Medical College (DMC), from January 2009 to December 2010 to explore whether malnutrition is an independent risk factor of stroke. Nutritional status of 100 stroke patients and 100 healthy controls were assessed in this study. Anthropometric measurements including Body Mass Index (BMI), Triceps skin fold (TSF), Mid-arm circumference (MAC) and Arm-muscle circumference (AMC) were measured within 7 days of stroke. Haemoglobin and haematocrit percentage, serum iron and serum albumin were measured at the same time. No significant difference was observed regarding TSF thickness, MAC, AMC, mean Hb and mean albumin level between the stroke patients and the control group, although iron level was significantly lower in stroke group. Multiple logistic regressions analysis showed that increase in age, smoking and decreased serum iron level has a positive association with stroke. Malnutrition is, according to this study, not a significant risk factor of stroke and triceps skin fold (TSF) thickness, mid-arm circumference (MAC), arm-muscle circumference (AMC), hemoglobin and serum albumin are not appropriate predictor of stroke.
