摘要: 目的 探究日均气温对深圳市中北部地区手足口病日发病数的影响,分析不同年龄段人群的效应差异。方法 收集2010—2023年深圳市中北部(龙岗区及龙华区)手足口病发病资料及气象资料。以24.6 ℃(P50)作为参照,应用分布滞后非线性模型分析气温与滞后天数对发病的影响,探究低温(P5=13.5 ℃)、高温(P95=30.0 ℃)的单日和累积滞后效应。结果 2010—2023年深圳市中北部累计报告手足口病250 138例,年均报告发病率为336.98/10万。滞后效应累积至21 d时,气温对手足口病的总体效应呈倒“V”型,在28.7 ℃时发病风险最大(RR=3.567,95% CI:3.279~3.880)。低温仅在滞后1~3 d、高温则在滞后1~21 d增加发病风险(RR>1)。低温的累积滞后效应为保护效应(RR<1),高温的为危害效应(RR>1)。低温、高温效应均对5岁以下儿童更显著。结论 日均气温对深圳市中北部手足口病日发病数呈非线性且具有滞后性,高温时应加强防控工作并重点关注<5岁儿童,低温时需关注≥5岁人群。

Abstract: Objective To investigate the effect of daily mean temperature on the daily incidence of hand, foot, and mouth disease (HFMD) in the north-central region of Shenzhen and to analyze the differential effects among various age groups. Methods Data on HFMD incidence and meteorological records from 2010 to 2023 were collected for the north-central districts of Shenzhen (Longgang and Longhua). A Distributed Lag Non-linear Model (DLNM) was employed to analyze the impact of temperature and lag days on HFMD incidence, using 24.6 ℃ (P50) as the reference. The single-day and cumulative lag effects of low temperature (P5=13.5 ℃) and high temperature (P95=30.0 ℃) were subsequently explored. Results A total of 250 138 HFMD cases were reported in north-central Shenzhen between 2010 and 2023, corresponding to an average annual incidence rate of 336.98 per 100 000 population. The overall temperature-HFMD association, cumulative over a 21-day lag, exhibited an inverted "V" shape, with the peak relative risk (RR) of 3.567 (95% CI: 3.279-3.880) occurring at 28.7 °C. Low temperatures were associated with an increased risk of incidence at lags of 1-3 days, whereas high temperatures demonstrated an increased risk across lags of 1-21 days (RR>1). The cumulative lag effect of low temperature was found to be protective (RR<1), while that of high temperature was detrimental (RR>1). The effects of both low and high temperatures were more pronounced in children under the age of five. Conclusions The relationship between daily mean temperature and the daily incidence of HFMD in north-central Shenzhen is non-linear and subject to a lag effect. Enhanced prevention and control measures are warranted during periods of high temperature, with a specific focus on children under five years of age. Conversely, during periods of low temperature, attention should be directed towards the population aged five years and older.
