Abstract


OBJECTIVES
The purpose of the present study was to estimate the prevalence of metabolic syndrome and to investigate the relation between metabolic syndrome and heart rate variability in a community population.
METHODS
The study design was cross-sectional, and 1028 subjects, aged 20~87 years, were recruited. Heart rate variability was measured in the sitting position for five minutes. The recorded data were assessed by time-domain (standard deviation of RR interval) and frequencydomain analysis. All subjects were examined for five components of metabolic syndrome.
RESULTS
The prevalence of metabolic syndrome in male and female subjects was 25.9% and 27.7%, respectively. The mean value of heart rate variability of the subjects was significantly different between healthy subjects and those with metabolic syndrome. The regression model showed that metabolic syndrome was negatively correlated with heart rate variability.
CONCLUSIONS
The results demonstrate that metabolic syndrome has potentially negative effects on the cardiovascular system, and that these effects could be detected by heart rate variability. Follow-up studies able to control the cohort effect are necessary to evaluate the relation between metabolic syndrome and heart rate variability.
