 note = {In Japan, sudden death in the bath (what is called ‘bath-related death’) has been reported in the elderly population in the
winter. Our continuous investigations into bath-related death in Kagoshima Prefecture from 2006 to 2008 have shown that
the death in Kagoshima occur at similar frequency as other prefectures in Japan, despite the warm environment in
Kagoshima. In this study, retrospective investigation of the inquest records in Kagoshima Prefecture in 2009 was
performed in order to obtain the better understanding of the factors associated with bath-related death, especially, the
relationship between the occurrence of the deaths and ambient temperature. The total number of the cases was 172 (83
males and 89 females), which corresponds to a crude mortality rate of 8.2 per 100,000 person-year. As previously reported,
most deaths occurred during winter season (52.9%), particularly on cold days. There was a significant negative correlation
between the incidence of the deaths during each month and monthly mean air temperature. Moreover, the incidence of the deaths showed significant negative correlation with ambient temperature including maximum, minimum and mean air
temperature of the day. Particularly, deaths occurred frequently on the days when the maximum, minimum and mean air
temperature was ＜15°C, ＜8°C ＜12°C, respectively. Further, the occurrence of the deaths significantly increased on the days
when intraday air temperature difference was ≥ 14°C. Accordingly, a great intraday temperature difference as well as low ambient
temperature should be a predisposing factor for bath-related death. In addition, most cases occurred in the home bath at
the time when elderly people usually bathe (4-8 p.m.). The time when deaths occurred in men tended to be earlier than
that in women, because elder Japanese men were accustomed to bathing first, so that they might enter a very cold
bathroom. Our results indicate that bath-related death occurs most often during the normal daily life of the aged. In order
to reduce the number of those tragic deaths in the bath, it is necessary to accumulate evidence by autopsy and by serial
investigations, and to prompt the government and society to develop protective activities.},
