Excess weight increases the risk of sarcopenia in patients with multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is an autoimmune neurodegenerative disease. Nutritional status influences the course of the disease, however, its relationship with sarcopenia needs further investigation. The aim of the study was to identify patients with sarcopenia and assess its association with nutritional status and the clinical course of the disease.

METHODS

The study assessed 110 patients submitted to evaluation of sociodemographic characteristics, level of physical activity, nutritional status, and presence of sarcopenia. The clinical course of the disease, age at onset, disease duration, disease-modifying therapy, and expanded scale of disability status (EDSS) were investigated.

RESULTS

Mean age was 37.17 (SD = 10.60) years, disease duration was 6.29 years (SD = 4.65), with a predominance of female gender (80.90 %), relapsing-remitting clinical form (RRMS) (89.10 %) and mild level of disability (EDSS median = 1.92). The group had excess weight (53.6 %) according to body mass index (BMI) and abdominal fat accumulation measured by waist circumference (WC) (53.6 %). High percentage of fat mass ( % FM) was observed in 54.5 % and 38.2 % of the patients according to bioimpedance (BIA) and ultrasound (US), respectively. It was observed that 15.5 % were at risk for sarcopenia, which was associated with excess weight, and high % FM (p<0.05).

CONCLUSION

These findings highlight the importance of including nutritional status indicators, and sarcopenia assessment in the care of patients with MS.
