Abstract P129: Association between Stressful Life Event and Resting Heart Rate in Korean Adults
Objective: Stress is associated with various cardiovascular disease and risk factors, but its association with resting heart rate has not been properly evaluated. This study evaluated an association between stressful life event (SLE) and resting heart rate (HR) in a Korean adult population.
Design: Cross-sectional analysis
Setting: Baseline health examinations of a community-based cohort
Participants: 1703 men and 2730 women, aged 27-87 years, who participated in health examinations of the Korean Genome and Epidemiology Study - Kanghwa study.
Methods: Life experience survey questionnaire was administered to measure SLEs experienced during the last 3 months. Resting blood pressure and HR were measured at least twice, and the average of the last two measurements was used for analysis. The association between SLE and HR was assessed by correlation coefficients and multiple linear regression analysis.
Results: When compared to people without SLE (mean 67.30 bpm), HR was significantly higher in those who experienced one (mean 64.45 bpm, p=0.002), two (mean 63.73 bpm, p<0.001), and 3+ SLEs (mean 64.17 bpm, p<0.001). This association remained even after adjustment for sex, age, body mass index, hypertension treatment, oral contraceptive use, postmenopausal hormone therapy, thyroid disease, liver disease, cigarette smoking, alcohol drinking, and BUN-creatinine ratio; compared to people with no SLE, those with 1, 2, and 3+ SLEs had lower resting HR by 1.485 bpm (p=0.005), 3.718 bpm (p<0.001), and 3.176 bpm (p<0.001), respectively.
Conclusion: Our findings suggest that experience of recent SLE is associated with lower resting HR in Korean adults.
