Relationship between Visceral Fat Obesity, Sleep Duration, and Lifestyle Habits among Japanese Occupational Population (FUJITSU Cardiovascular and Respiratory Observational Study-3; FACT-3)

Abstract Aims We investigated the relationship of visceral fat obesity (VFO) with sleep duration and other lifestyle factors by gender. Methods This was a single-center descriptive epidemiological survey and cross-sectional survey that investigated and analyzed VFO for 24,279 white-collar workers aged 30 to 59. Results When 7-hour sleepers were taken as the control, a U-shaped relationship between sleep duration and the comorbid VFO in male and a trend toward the higher the morbid VFO among female subjects with shorter sleep duration were found. Moreover, insomnia and poor activity strongly linked with VFO in male, on the other, high age strongly linked with VFO in female. In shorter sleepers, overtime work in male and insomnia in female were also associated with VFO. Conclusions In active workers, more short sleepers had comorbid VFO, which was related to insomnia, overwork, and absence of exercise habit in male; high age and insomnia in female. Even in long male sleepers, VFO tended to be comorbid, and it was related to the presence of insomnia and the absence of exercise habits.
