Insomnia is one of the most common complaints at worksites, as well as in the general population. This study aims to assess the effect of @entity22 on the development of @entity101 in Japanese male workers. Using the annual health examination database of a Japanese telecommunication company, eligible middle-aged male @entity1 in the 1994 health examination were followed up until 1998 or the development of @entity101 (either initiation of antihypertensive therapy or a systolic blood pressure > or = 140 mmHg and/or a diastolic blood pressure > or = 90 mmHg). The effect of difficulty initiating sleep (DIS) was assessed with a DIS dataset (n=4,794), which included non-DIS (n=4,602) and persistent-DIS (n=192) subjects. That of difficulty maintaining sleep ( @entity13337 ) was assessed with a @entity13337 dataset (n=4,443), which included non- @entity13337 (n=4,157) and persistent- @entity13337 (n=286) subjects. The incidence of @entity101 among persistent-DIS (40.1%; 130.7 per 1,000 @entity1 -yr) was significantly higher than that among non-DIS (30.6%; 89.9 per 1,000 @entity1 -yr). The incidence of @entity101 among persistent- @entity13337 (42.3%; 136.7 per 1,000 @entity1 -yr) was significantly higher than that among non- @entity13337 (30.7%; 90.8 per 1,000 @entity1 -yr). After adjusting for potential confounding factors (i.e. age, body mass index, smoking, @entity167 drinking, and job stress), persistent complaints of DIS and @entity13337 were significantly associated with an increased risk of @entity101 (OR=1.96; 95%CI: 1.42-2.70 and OR=1.88; 95%CI: 1.45-2.45, respectively). Persistent @entity22 may be a useful predictor of @entity101 in Japanese male workers.
