Abstract:
Objective To assess the impact of heat waves on non-accidental deaths,and to investigate the influencing factors for deaths caused by heat waves in Jinan,China.Methods Daily death data and meteorological data for summer days with or without heat waves in Jinan from 2012 to 2014 were collected,and a cross-over analysis was conducted to evaluate the influence of heat waves on non-accidental deaths and deaths caused by other reasons.The univariate and multivariate logistic regression models were used to investigate the influencing factors for deaths caused by heat waves.Results The risks of non-accidental deaths and deaths caused by circulation system diseases during the days with heat waves were 1.82 times (95％ CI:1.47～2.36) and 1.53 times (95％ CI:1.14～2.07) those during the days without heat waves.The multivariate logistic regression analysis showed that old age (≥75 years)(OR=1.184,95％ CI:1.068～1.313),low educational level (OR=1.187,95％ CI:1.064～1.324),and deaths outside hospital (OR=1.105,95％ CI:1.009～1.210) were associated with the high risk of deaths during the days with heat waves.Conclusion Heat waves significantly increase the risk of non-accidental deaths and deaths caused by circulation system diseases in Jinan,and the deaths during the days with heat waves are related to age,educational level,and place of death.
