摘要
目的探讨2011—2013年热浪对广州市感染性腹泻发病的影响。方法利用时间分层的病例交叉设计探讨热浪对感染性腹泻发病的影响,将研究对象按年龄、性别分成男性、女性组及≤14岁、15~60岁、>60岁年龄组,分别探讨热浪的效应。结果热浪发生后,该地区总人群和>60岁人群感染性腹泻的发病危险均在滞后第1天时下降,RR值分别为0.882(95%CI:0.779~0.998)和0.594(95%CI:0.370~0.954);男性人群和≤14岁人群感染性腹泻的发病危险分别在滞后第3天和滞后第14天升高,RR值分别为1.173(95%CI:1.009~1.364)和1.186(95%CI:1.018~1.382);热浪对女性和15~60岁年龄组人群感染性腹泻的发病影响无统计学意义(P>0.05)。结论热浪可增加男性人群和≤14岁人群感染性腹泻的发病风险,且存在滞后效应,应注意预防热浪发生后感染性腹泻的发生。
Objective To explore the impacts of heat wave on the incidence of infectious diarrhea in Guangzhou.Methods The studied subjects were divided into male group,female group,≤14 age group,15-60 age group and>60 age group by sex and age.Time-stratified case-crossover design was used to evaluate the associations between heat wave and incidence of infectious diarrhea in each group.Results After heat waves,the risks of infectious diarrhea in total population and>60 age group decreased,reaching to minimums both on the 1 lag day,the RR values were 0.882(95%CI:0.779-0.998)and 0.594(95%CI:0.370-0.954)respectively.The risks of infectious diarrhea in male and≤14 age groups increased,reaching to maximums on the 3,14 lag days respectively,and the RR values were 1.173(95%CI:1.009-1.364)and 1.186(95%CI:1.018-1.382).There was no significant relationship between heat wave and incidence of infectious diarrhea in female and 15-60 age groups.Conclusion The heat wave may increase the risk of infectious diarrhea in male and population aged≤14 years in this area with lag effects,the prevention of infectious diarrhea after heat wave should be paid more attention to.
