Correlation between metabolic syndrome disorder and circadian rhythm of physically disabled individuals

Abstract

Objectives. The aim of this study was to examine the correlationbetween sleep disorder and metabolic syndrome disorder in physically disablepeaple. Methods. Thestudy was conducted among physically disabled persons who were selected fromthe Education and Rehabilitation Centre of Disabled People in Çorum, a citylocated in the central north of Turkey. Sleep quality is assessed with Turkishversion of Pittsburgh Sleep Quality Index. The metabolic syndrome disorder,weight circumference and blood values of participants are examined by threehealth personnel from a private hospital in Çorum. Results. Onehundred and three persons (56 M, 47 F) participated inthis study. Metabolic syndrome disorder was found in 23(22.3%) participants. Forty (38.8%) participants had badsleep quality. The correlation between circadian rhythm and metabolic syndromedisorder was significantly positive (p< 0.01). It was found that the persons who have a bad sleep quality spendmore energy than the persons who have good sleep quality (p = 0.001). Energy expenditure of the participants with metabolic syndrome disorder is higherthan without metabolic syndrome disorder(p < 0.001) at the time ofsleeping. Conclusions.This study confirms the positive relationship betweencircadian rhythm irregularity and metabolic syndrome disorder. Also, the studysupports the idea that circadian rhythm irregularities cause an increase indaily energy expenditure which leads further metabolic syndrome disorder.
