深圳市宝安区散居儿童家长手足口病健康教育短信效果评价

Assessment of the effect of HFMD-related health knowledge promotion messages based on the Joinpoint regression analysis

目的评价向深圳市宝安区散居儿童家长发送的手足口病健康教育短信对手足口病的防治效果。方法利用金卫信公司开发的深圳市儿童预防接种信息管理系统平台向深圳市宝安区散居儿童家长群发短信开展手足口病健康知识宣传,对宝安区2017年和2018年手足口病周发病率进行Joinpoint回归分析得到发病率随时间变化趋势,并与深圳市对应时段的手足口病周发病率变化趋势进行比较。结果2017年与2018年宝安区与深圳市的手足口病周发病率趋势均呈双峰态势——夏季和秋季高峰。2017年内,宝安区与深圳市的手足口病周发病率变化趋势大体一致。2018年宝安区夏季高峰提前约5周,峰值是同年深圳市夏季高峰峰值的1.60倍、是2017年宝安区夏季高峰峰值的2.62倍,但健康教育短信发送后,宝安区周发病率快速下降,下降速率是深圳市同期的1.84倍,此后宝安区秋季高峰与深圳市同期趋势基本一致,且该秋季高峰时段内宝安区周发病率均低于2017年同期。2018年宝安区手足口病病例中散居儿童所占比例显著低于2017年(χ~2=553.37,P<0.001)。结论2018年5月24日面向宝安区散居儿童家长的手足口病短信健康教育可能对宝安区手足口病疫情起到了一定的防控作用。

Objective To assess the effect of HFMD-related health knowledge promotion messages on HFMDcontrol in Baoan District,Shenzhen.Methods Shenzhen Children Vaccination Information Management System Platform was used to send HFMD-related health knowledge promotion messages to guardians of scattered children in Baoan District.Joinpoint regression model was used to analyze and compare the trends with the incidence of HFMD in Baoan District and Shenzhen City in 2017 and 2018.Results There were two high high-risk period of HFMD in both Baoan District and Shenzhen City in 2017 and 2018,which appeared as double peaks on each trend chart-summer peak and autumn peak.In2017,the trends in weekly incidence in Baoan District was basically similar to that in Shenzhen City.In 2018,the summer peak in Baoan District was 5 weeks earlier than that in 2017,and its peak value was 1.60 times to that in Shenzhen City in2018 and 2.62 times to that in Baoan District in 2017.After the HFMD health education text messages were sent,the incidence of HFMD in Baoan District was declined rapidly and the rate of incidence decrease was 1.84 times that in Shenzhen City,and the following autumn peak in Baoan District was much lower than that in the same period in 2017.The percentage of scattered children among total new cases in 2018 was significantly lower than that in 2017(χ~2=553.37,P<0.001).Conclusion The HFMD health education text messages might play a role in the prevention and control of HFMD among scattered children in Baoan District.
