| Research Abstract |
Police officers in Japan have more proportion of overweight than general population; therefore we presumed that police officers might be more prevalent in sleep-disordered breathing (SDB). The objectives of this study are 1) to clarifythe prevalence of SDB; 2) to examine the associations of SDB with obesity; 3) to examine the associations of SDB with subjective sleepiness and objective alertness among Japanese police officers. We found that the prevalence of SDB and overweight among police officers were approximately 20% and more than 50%, respectively. We also observed the positive associations of age and BMI with 3% oxygen desaturation index. We found that the severity of SDB was positively associated with both subjective sleepiness and objective alertness indicators, but there were no differences of prediction ability for SDB between relationship of SDB with objective alertness and that with subjective sleepiness.
