Insomnia is the most prevalent sleep disorder and co-occurs with many health problems. Lmited evidences investigated the association between insomnia and atrial fibrillation (AF). This study aims to investigate possible association between insomnia and AF.
A total of 8371 participants (4314 men, mean age 42.4± 13.1 years) were enrolled in a cross-sectional study in China to investigate the association between insomnia and AF. AF was assessed by a standard supine resting, 10-s 12-lead ECG or a self-reported history. Insomnia was assessed using the Athens Insomnia Scale (AIS) and a score of six or above was considered insomnia. The relationship between insomnia and AF was analyzed by using logistic regression.
Of the 8371 participants, 1074 (12.8%) suffered from different degrees of insomnia. After adjusting for common confounders, individuals with insomnia have a moderate increased likelihood of suffering from AF compared with people who did not with insomnia (odds ratio (OR): 1.92, 95% confidence interval (CI): 1.00-3.70, p=0.050). After stratified by age, positive association was more profound in those aged< 40 years (OR: 6.52, 95%CI: 1.654-25.83, p=0.008).
Insomnia maybe associated with a higher risk of AF in Chinese population, especially those aged< 40 years.
