Objective：This study aimed to clarify the relationship between sleep
and subjective health condition by focusing on disaster-affected
workers six months after the Kumamoto earthquake.
Methods：The study population comprised 676 workers at small andmedium-sized companies located in Kamimashikigun, Kumamoto
Prefecture, where damage after the Kumamoto earthquake wassevere. Participants were sent a questionnaire with items related tobasic characteristics（sex, age, and family members）, damage tohome after the earthquake, subjective symptoms after theearthquake, injury from the earthquakes, changes in income,subjective wellbeing, changes in workload after the earthquake,
Athens Insomnia Scale（AIS）, Impact of Event Scale-Revised（IES-R）, General Health Questionnaire（GHQ 28）, and healthrelated QOL Short-Form Health Survey（SF-8）. Responses werecollected from 456 people at 13 companies（68.1% response rate）. Of
these, 438 responses（96.1%）were valid. This study was approved by
the ethical review committee of Fukuoka University School ofMedicine.
Results：The participants included 334 males and 104 females withan average age of 43.3 years. Two groups were created based on
Abbreviated Injury Scale（AIS）scores：279 participants were in theinsomnia group and 159 participants were in the non-insomniagroup. Compared with that in the non-insomnia group, the patientsin the insomnia group were old, had poor subjective health status,
and were more likely to have subjective symptoms and injury after
the earthquake. The study found a significant positive correlation
with intrusion and hyperarousal symptoms in the IES-R subscales.
In the SF-8 responses, there were significant negative correlations
with BP（Bodily Pain）, GH（General Health）, VT（Vitality）,SF（Social Functioning）, RE（Role Emotional）, MH（Mental Health）,and MCS（Mental Component Summary）. In a logistic regression
analysis of sleeping condition in Athens Insomnia Scale（AIS）, BP［OR： 0.942, CI： 0.907-0.978］and avoidance symptoms［OR：0.881, CI：0.799-0.971］improved sleeping condition, whereas
hyperarousal symptoms［OR：1.553, CI：1.324-1.823］, social life
function［OR：0.954, CI：0.916-0.994］, and daily role function（mental）［OR：0.916, CI：0.866-0.97］were negatively related withgood sleeping condition.Discussion：The Kumamoto earthquake
influenced the sleep quality for most disaster-affected workers, withapproximately 60% reporting insomnia. Because workers withinsomnia may exhibit hidden subjective symptoms or suffer frommental stress, long-term preventive systems should be developedand established by companies to improve worker health.
Longitudinal studies are required to further examine factors related
to sleep condition and outcomes of support systems.
