    Abstract:
    BACKGROUND: This current study is aimed at investigating the effect of physical activities and meteorological conditions on the sudden deaths of children without obvious causes at school. METHODS: The subjects are 76 victims of sudden death at school in the 12 years from 1983 to 1994 in Aichi Prefecture, Japan. The incidence of these sudden deaths is shown by month of the year, day of the week and hour of the day in relation to physical activities and meteorological factors. The analysis of Hayashi's quantitation type II was used for evaluation of the relationship between sudden deaths under the different physical conditions, such as sedentary (at rest or slow walking) or active (running, competitive sports or swimming) conditions, and meteorological or weather factors such as, season of the year, wind-chill factor, atmospheric pressure and relative humidity. RESULTS: Of 76 cases, 21 died suddenly under sedentary physical conditions and 55 under active conditions. The incidence of sudden death was highest from 10.00 to 11.00 h and on Thursday. Sudden death under sedentary conditions was associated with autumn and winter or with winter with high humidity and low atmospheric pressure. Sudden deaths during running were associated with spring with low humidity and high pressure and sudden deaths during competitive sports were associated with dry and cloudy weather. CONCLUSION: Sudden deaths in children at school may be associated with physical activities and meteorological conditions.
