Malnutrition Rate in Stroke Patients on Admission

Malnutrition is frequently observed in patients with acute stroke and its prevalence after stroke varies widely among published reports. Differences in the timing of assessment, stroke type, comorbid medical conditions, and stroke complications may have contributed to this large variability. This study is conducted to investigate the prevalence of malnutrition, and its associated risk factors in stroke patients admitted to our stroke clinic.

A prospective design was used to measure the nutritional status and nutritional risk of stroke patients during hospitalisation between June 2016 and February 2017. Nutritional status was measured at admission. Demographic data and information on clinical variables were collected, which included the patient's age, gender, type of stroke and other comorbid disorders. Blood samples, including concentrations of high-sensitivity C-reactive protein (CRP), serum albumin, serum creatinine, lipid profile and serum lymphocyte count, were measured by routine methods. Nutritional status was measured using the Mini Nutritional Assessment (MNA); for elderly stroke patients (age older than 65). For stroke patients younger than 65 age, Nutrition Screening 2002 (NRS 2002) was used.

318 patients with acute stroke were assessed for their nutritional status at admission. There were 145 (45%) female and 173 (55%) male patients. Their mean age was 66.16±14.32. 66.1% of the patients elder than 65 years were malnourished. 12.2% of the patients younger than 65 years were found to be malnourished. We found no relationship between comorbidities and malnutrition, except hyperlipidemia. Nourished stroke patients older than 65 years had higher serum lipid levels than the malnourished patients. We also found no relationship between malnutrition biomarkers and being malnourished.

Malnutrition is frequently observed in patients with stroke. Early recognition of malnutrition is crucial, but the absence of valid markers hampers to find out the presence of malnutrition. Thus, further research is needed in targeting the modifiable nutrition risk factors and give attention to nutrition in stroke patients.
