Background: Muscle wasting and obesity may complicate the post-stroke trajectory. We investigated the relationships between nutritional status, body composition and mobility one year after stroke.
Methods: Among 279 eligible home-living individuals who had suffered a stroke 1-2 years earlier, 134 (74±5 years, 69% men) were examined according to the Mini Nutritional Assessment-Short Form (MNA-SF, 0-14 points, including body mass index [BMI, kg/m2]); body composition by bio-impedance analyses; the Short Physical Performance Battery (SPPB, 0-12 points) combining walking speed, balance and chair stand capacity, and the self-reported Physical Activity Scale for the Elderly (PASE).
Results: BMI>30 kg/m2 was observed in >20%, while 14% were at risk for under-nutrition according to MNA-SF. Sarcopenia, i.e. a reduced fat-free mass index (FFMI) and slow self-selected gait speed (<1.0 m/s), was noticed in 3%. Eight percent displayed sarcopenic obesity, defined as reduced FFMI and increased fat-mass index (FMI). SPPB scores ≤9 in 40% indicated high risk for disability. Mobility was not associated with FFMI or FMI. Multivariate logistic regression indicated that low mobility, i.e., SPPB ≤9 points, was independently related to risk for under-nutrition (OR 5.8, CI 1.6-21.1), low physical activity (OR 8.2, CI 2.8-24.2) and high age (OR 2.78, CI 1.24-6.24).
Conclusions: Nutritional disorders, i.e. obesity, sarcopenia, sarcopenic obesity or risk for under-nutrition, were observed in about one third of individuals one year after stroke. Risk for under-nutrition, self-reported physical activity and age were related to mobility, while FFM and FM were not. Nutrition and exercise may be rehabilitation opportunities after stroke.
