Abstract:
Objective To investigate the epidemiological features of heatstroke in Shaoxing,China in 2008-2014,and to provide a reference for developing prevention and control measures for heatstroke.Methods The reports on heatstroke in Shaoxing in 2008-2014 were collected from the China Information System for Disease Control and Prevention,and the data were summarized and analyzed.Results A total of 1 676 heatstroke cases were reported in Shaoxing in 2008-2014,among which 1 485 cases (88.6％) were mild heatstroke and 191 cases(11.4％) were severe heatstroke.Nine persons died of severe heatstroke,and the fatality rate was 0.5％(9/1 676).Among these persons,4(44.4％,4/9) were the elderly living at home,4 (44.4％,4/9) were farmers (working outdoors),and 1(11.2％,1/9) was unemployed.The male patients with heatstroke accounted for 66.3％(1 111/1 676),and those with severe heatstroke accounted for 13.1％(146/1 111);the female patients with heatstroke accounted for 33.7％(565/1 676),and those with severe heatstroke accounted for 8.0％(45/565);there were significant differences between male and female patients(x2=9.94,P=0.002).The mean age of patients with heatstroke was 48.7±18.8 years;the mean age of male patients was 49.8±17.9 years,and that of female patients was 46.6±20.3 years,with a significant difference between the male and female patients (t=3.19,P＜0.001).Most of the patients experiencing heatstroke were in their forties or fifties,each accounting for 19.2％(321/1 676);in male patients who experienced heatstroke,those in their fifties accounted for the highest percentage(21.5％,239/ 1 111),and in female patients who experienced heatstroke,those in their twenties accounted for the highest percentage (18.9％,107/565).Based on stratification by age,the severity of heatstroke differed significantly between male and female patients in their forties,fifties,sixties,seventies,and eighties (P＜0.05).Most of the cases of heatstroke occurred in June to September,accounting for 98.9％(1 657/1 676),particularly in July and August,accounting for 87.1％(1 460/1 676).Conclusion In Shaoxing,heatstroke usually occurs in summer,and most cases are mild.Middle-aged and elderly men and farmers (working outdoors) are susceptible to heatstroke,and warnings on heatstroke and emergency treatment of severe heatstroke should be enhanced.
