Associations Between Obstructive Sleep Apnea, Metabolic Syndrome, and Sleep Duration, As Measured With an Actigraph, in an Urban Male Working Population in Japan

Abstract

Although increased BMI and age both had a significant effect on the prevalence of OSA in patients with Mets, one of 6 subjects with Mets, but only one of 40 without Mets had severe OSA in an urban male population in Japan. Physicians should take into account this high prevalence of severe OSA in patients with Mets. Sleep duration should be taken into consideration as an important factor in studies investigating the prevalence of severe OSA and Mets.
