Background: Many studies have demonstrated that excessively long or short sleep duration and insomnia are associated with high risk of mortality. We intended to investigate the lifestyle and the state of health in frequently sleep interrupted people.
Methods: We have examined 2,540 subjects who visited a comprehensive medical testing center from January 2001 to June 2003. We divided into two groups of sleep disturbance into frequently interrupted group (two or more times per night) and infrequently interrupted group (less than twice per night). After frequency matching by age and sex, 1,900 subjects (each group of 950 subjects) were selected. Lifestyle, self-health perception, symptoms, clinical laboratory data and past history were compared by chi-square test and student’s t-test. To identify the factors that influenced on sleep interruption, multiple logistic regression analysis was done.
Results: Sleep duration was not significantly different in both groups (P=0.486). The frequently interrupted group were likely to perceive themselves as bad state of health being in a (P=0.008) and to complain of various symptoms, i.e., fatigue (P＜0.001), headache (P= 0.001), etc. Also, they had more incidence of mood disorders (P= 0.002), fatty liver (P=0.008), and arthritis (P=0.001) than the other group. By multiple logistic regression analysis, alcohol consumption (OR: 1.344, P= 0.007), irregular diet (OR: 1.325, P=0.003), and coffee intake (OR: 0.786, P= 0.013) were significantly different between the frequently interrupted group and the other group.
Conclusion: Patients who complain of insomnia should be evaluated on both sleep duration and interruption. The evaluation of sleep interruption is needed in patients who perceive themselves as being in a bad state of health, who complain of various symptoms (fatigue, headache, etc.), or have a history of mood disorder, fatty liver, or arthritis.
