The Relationship between Resting Heart Rate and Prevalence of Metabolic Syndrome and Type 2 Diabetes Mellitus in Korean Adults: The Fifth Korea National Health and Nutrition Examination Survey (2012)

ABSTRACT

BACKGROUND: The purpose of this study was to examine the association between resting heart rate (RHR), the risk factors and prevalences of metabolic syndrome (MetS) and type 2 diabetes (T2D) in Korean adults. METHODS: A cross sectional analysis was performed on data from the 2012 Korea National Health and Nutrition Examination Survey (KNHANES V) using frequency analysis, analysis of covariance (ANCOVA), and logistic regression. Participants were stratified according to RHR into 5 groups; or =90 bpm. RESULTS: The results show that risk factors of MetS and T2D increased as RHR increased. Compared to those with a RHR of or =90 bpm by 1.46 (95% confidence interval [CI] 1.03-2.08), 2.05 (95% CI, 1.42-2.96), 2.34 (95% CI, 1.57-3.48), and 2.34 (95% CI, 1.23-4.47), respectively. Similarly, compared to those with a RHR of or =90 bpm by 1.01 (95% CI, 0.72-1.41), 1.44 (95% CI, 1.02-2.05), 1.83 (95% CI, 1.25-2.68), and 2.40 (95% CI, 1.30-4.44), respectively. CONCLUSION: In conclusion, RHR was significantly associated with risk factors and prevalences of MetS and T2D. This study suggests that RHR is associated with MetS and T2D and can be used to predict such diseases.
