| Research Abstract |
Participants were about 8000 employees in Hokkaido. Our results indicated that (1) the prevalence of insomnia in female subjects (31.0%) was significantly larger than in males (23.2%), but the gender difference disappeared after adjustment for paid work and family responsibilities, (2) daily sleep duration of 9 hours or more was associated with elevated values of baPWV as a marker of arterial stiffness, (3) lower employment level was significantly associated with a higher risk of insomnia.
