Abstract:Objective To study the effects of resting heart rate (RHR) on metabolic syndrome (MS) in healthy population. Methods The health examinees of our hospital from January 2011 to December 2012 were selected as the research subjects and followed up for 5 years. Logistic regression was used to analyze the relationship between different RHR levels and the incidence of MS. Results After 5-year follow-up, the incidence of MS in both male and female groups increased with the increase of RHR (χ2 male=10.039, P = 0.002; χ2 female=48.437, P = 0.000). For the total population, the risk of MS increased significantly with the increase of RHR by 1 unit, and the difference was still statistically significant after adjusting for age, BMI, health-related behavior and pre-existing MS components [Ol ^ R=1.320 (95% CI=1.201, 1.451); P = 0.000]. There was still significant difference after sex stratification [male group: Ol ^ R=1.192 (95% CI=1.040, 1.367), P = 0.012; female group: Ol ^ R=1.409 (95% CI=1.235, 1.608), P < 0.001]. For the total population, RHR<70/min as the control group, the risk of MS in the remaining three groups were significantly increased, and OR showed an increasing trend; after correction of age, BMI, health-related behavior and pre-existing MS component, there was still significant significance [RHR<90/min group: Ol ^ R=2.327 (95% CI=1.784, 3.037), P = 0.000]. There was still significant difference after sex stratification [[RHR>90/min group: male group: Ol ^ R=1.644 (95% CI=1.148, 2.355), P = 0.007; female group: Ol ^ R=3.375 (95% CI=2.214, 5.146), P < 0.05]. Conclusions In conclusion, an increase in resting heart rate was an independent and signi?cant predictor of MS in all people, especially in women.
