理想心血管健康行为和因素对静息心率的影响

Impact of ideal cardiovascular health behaviors and factors on resting heart rate in individuals without cardiovascular diseases

目的 探讨理想心血管健康行为和因素对静息心率（RHR）的影响.方法 采用横断面研究方法,以2006至2007年度开滦集团公司健康体检职工为研究对象,排除心律失常、血红蛋白≤90 g/L、服用影响心率药物、既往有卒中、心肌梗死、恶性肿瘤病史者,最终纳入统计的职工共83 824名.对研究对象进行统一问卷调查和血液生化检查,采用多因素logistic回归分析理想心血管健康行为和因素对RHR的影响.结果 （1）理想心血管健康行为和因素数量为0、1、2、3、4、5和≥6项职工的RHR分别为（76.4±10.3）、（75.2±10.3）、（74.3±9.9）、（73.6±10.0）、（72.6±9.9）、（72.1±9.7）和（71.8±9.2）次/min（P ＜0.01）.（2）多因素logistic回归分析显示,校正性别、年龄、甘油三酯、高密度脂蛋白胆固醇、高敏C反应蛋白、经常饮茶和饮酒后,与具有0项者比较,具有1、2、3、4、5和≥6项理想心血管健康行为和因素者RHR≥80次/min的风险逐渐降低,OR（95％ CI）分别为0.79（0.71 ～0.87）、0.68（0.62 ～0.75）、0.61（0.55 ～0.67）、0.52（0.47 ～0.58）、0.50（0.44 ～0.56）、0.49（0.40 ～0.60）.结论 理想心血管健康行为和因素与较低RHR有关.

Objective To investigate the impact of ideal cardiovascular health behaviors and factors on resting heart rate （RHR）.Methods A cross-sectional study method was used in our study.83 824 workers who had participated in the 2006-2007 Kailuan health examination were included,individuals with arrhythmia,hemoglobin ≤ 90 g/L,taking drugs which might affect RHR,history of cerebral infarction or myocardial infarction or cancer were excluded.Related information was obtained from the unified questionnaire,blood biochemistry was performed.Multivariate logistic regression was used to analyze the impact of ideal cardiovascular health behaviors and factors on the RHR.Results （1） The RHR was （76.4 ±10.3）,（75.2 ±10.3）,（74.3±9.9）,（73.6±10.0）,（72.6±9.9）,（72.1 ±9.7） and （71.8 ±9.2）beats/min in workers whose number of ideal cardiovascular health behaviors and factors was 1,2,3,4,5 and≥ 6 respectively（P 〈 0.01）.（2） Multivariate logistic regression showed that,after adjusted by gender,age,triglyceride,high density lipoprotein cholesterol,high-sensitive C-reactive protein,tea drinking,alcohol drinking,the risk of RHR ≥ 80 beats/min gradually reduces along with the increasing of number of ideal cardiovascular health behaviors and factors （1,2,3,4,5 and ≥ 6） compared with those who did not have ideal cardiovascular health behaviors and factors,the value of OR （95 % CI） was 0.79 （0.71-0.87）,0.68（0.62-0.75）,0.61（0.55-0.67）,0.52（0.47-0.58）,0.50（0.44-0.56）,0.49（0.40-0.60）respectively.Conclusion Ideal cardiovascular health behavior and factors is related to lower RHR in individuals without cardiovascular diseases.
