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)

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.
