The Influence of Nutritional Changes on the Motor Skills in Children With Tumors of Central Nervous System and Acute Lymphoblastic Leukemia in Remission

Abstract

The paper presents the results of the analysis of associations between motor skills (MS) and nutritional status (NS) in 102 children who have received treatment of CNS tumors (n=53) and ALL (n=49). Median of remission interval was 2 years (from 3 month to 10 years). MS was evaluated by Bruininks-Oseretsky Test of Motor Proficiency. NS was assessed using anthropometry and bioimpedance analysis. As a result, it was found that children after cancer treatment have motor and nutritional deficiencies. Low values of NS indicators (lean body mass, cell mass, mid-arm muscle circumference (MAMC)) are associated with a decrease in MS parameters. There was no dependence between the value, dynamics of body fat mass and MS. In those children who had a positive dynamics (+3%) of the phase angle and MAMC for 3 weeks of the observation changes in MS were also significantly positive - in contrast to the overall sample, where any reliable dynamics of MS parameters was not revealed.
