Nutritional status in acute stroke: undernutrition versus overnutrition in different stroke subtypes

Nutritional status in the acute stage of stroke has not been properly evaluated in different stroke subtypes. The objective of this study was to investigate the nutritional status of different subtypes of stroke patients.

We studied 88 female patients with first-ever strokes. Strokes were divided into cerebral infarction (CI, n=67) and intracerebral hemorrhage (ICH, n=21). We measured the nutritional status of the patients in the acute stage of stroke with the use of 8 parameters including 3 biochemical and 5 anthropometric ones. These variables were assessed in stroke patients and 120 age-matched controls, and were compared with each other.

In the acute stage of stroke, undernourishment was significantly (P=0.000) more prevalent in the ICH group (62%) than in the CI group (25%) or controls (13%). On the other hand obesity was present in 10%, 24% and 17% in patients with ICH, those with CI, and controls, respectively, which was not significantly different (P=0.461). Only abdominal skinfold thickness was significantly greater in patients with CI than in those with ICH or controls. Conclusions - Our results illustrate that undernourishment is prevalent in acute stroke patients, significantly more so in patients with ICH than in those with CI. Stroke patients, especially those with ICH, should receive special nutritional intervention starting immediately after admission.
