Key result
High blood pressure was strongly associated with an increased likelihood of accelerated resting heart rate among college freshmen.
Why the study?
Accelerated resting heart rate increases cardiovascular disease risk, but little research has reported its prevalence and associated influencing factors among young individuals around 18 years old.
Cross-Sectional (n=12,428)
No
Accelerated resting heart rate is highly prevalent among college freshmen and is associated with female sex, high blood pressure, and urban origin, highlighting the need for early cardiovascular risk management.

Accelerated RHR prevalence and factors in freshmen merit attention in young adults; cross-sectional data leave causality and interventions open.
Objective This study aimed to investigate the prevalence of accelerated resting heart rates (RHRs) among freshmen in a university in Wuhan and to explore the influencing factors. Methods We conducted a cross-sectional survey and physical examinations in a university in Wuhan from 2015 to 2017, including 12428 freshmen. A binary logistic regression model was undertaken to identify the influencing factors associated with their accelerated RHRs. Results The prevalence of accelerated RHRs was 47.5% among the 12428 freshmen surveyed. Accelerated RHR of freshmen was related to female (odds ratio [OR]: 1.484, 95% confidence interval [95% CI]: 1.368 - 1.610, P < 0.001) and high blood pressure (OR: 2.709, 95% CI: 2.212 - 3.318, P < 0.001). Compared with rural students, accelerated RHR was more likely to occur in urban students (OR: 1.452, 95% CI: 1.333 - 1.583, P < 0.001). Additionally, students who came from the central and the eastern regions (OR: 1.452, 95% CI: 1.254 - 1.682, P < 0.001; OR: 1.363, 95% CI: 1.149 - 1.618, P < 0.001), rather than who came from the western regions, were more likely to have accelerated RHRs. Conclusions Students with accelerated RHRs made up a high proportion of college freshmen entering the university in 2015 – 2017 in Wuhan. For people aged around 18 years, more attention was needed to pay to RHRs and specific measures such as blood pressure management were required in advance to prevent accelerated RHRs. Key questions What is already known about this subject? Accelerated resting heart rate (RHR) could significantly increase the risk of suffering from cardiovascular diseases (CVDs). However, little research had reported the influencing factors associated with accelerated RHR among the young around 18 years old. What does this study add? We conducted a survey on freshmen to investigate the influencing factors associated with accelerated RHR, so as to provide early warning information for the occurrence of CVDs in a visual way. How might this impact on clinical practice? This study might serve as a reminder to young people to pay more attention to RHRs and provide early warning information about CVDs.

You et al. (2020) conducted a cross-sectional in Accelerated resting heart rate (n=12,428). High blood pressure vs. Normal blood pressure was evaluated on Accelerated resting heart rate (>80 beats per minute) (OR 2.709, 95% CI 2.212 - 3.318, p=< 0.001). High blood pressure was strongly associated with an increased likelihood of accelerated resting heart rate among college freshmen.
