Key result
In Korean adults, a resting heart rate of ≥ 90 bpm was associated with a significantly higher prevalence of metabolic syndrome (OR 2.34) and type 2 diabetes (OR 2.40) compared to < 60 bpm.
Why the study?
Is higher resting heart rate associated with an increased prevalence of metabolic syndrome and type 2 diabetes in Korean adults?
Cross-Sectional (n=5,870)
Is higher resting heart rate associated with an increased prevalence of metabolic syndrome and type 2 diabetes in Korean adults?
Odds Ratio: 2.34 (95% CI 1.23–4.47)
Higher resting heart rate is significantly associated with an increased prevalence of metabolic syndrome and type 2 diabetes in Korean adults, suggesting its potential utility as a simple predictive marker.
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; < 60 bpm, 60-69 bpm, 70-79 bpm, 80-89 bpm, and ≥ 90 bpm. Results:The results show that risk factors of MetS and T2D increased as RHR increased.Compared to those with a RHR of < 60 bpm, the prevalence of MetS increased in those with RHR of 60-69 bpm, 70-79 bpm, 80-89 bpm and ≥ 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 < 60 bpm, the prevalence of T2D increased in those with RHR of 60-69 bpm, 70-79 bpm, 80-89 bpm, and ≥ 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.

Park et al. (2015) conducted a cross-sectional in Metabolic Syndrome and Type 2 Diabetes (n=5,870). Resting heart rate ≥ 90 bpm vs. Resting heart rate < 60 bpm was evaluated on Prevalence of metabolic syndrome (OR 2.34, 95% CI 1.23-4.47). In Korean adults, a resting heart rate of ≥ 90 bpm was associated with a significantly higher prevalence of metabolic syndrome (OR 2.34) and type 2 diabetes (OR 2.40) compared to < 60 bpm.
