摘要:
目的 探讨气象因素对手足口病(hand-foot-mouth disease, HFMD)发病的影响与滞后效应。 方法 收集整理南宁市2010—2019年HFMD日发病数据及同期气象资料,运用分布滞后非线性模型(distributed lag non-linear models, DLNM)分析南宁市HFMD发病与气象因素的相关性。 结果 南宁市2010—2019年HFMD累计报告508 984例,发病主高峰在每年4—6月,次高峰在9—10月;男女报告发病率之比为1.57∶1,以幼托儿童和散居儿童为主。HFMD发病与气温、相对湿度和日照时数呈正相关,与气压呈负相关。气温为35.0 ℃,滞后d 9时RR值最大(RR=1.058,95% CI:1.037~1.079);相对湿度为86.0%,滞后d 14时RR值最大(RR=1.011,95% CI:1.007~1.014);气压呈“双峰”现象,气压为990.0 hpa滞后d 4时RR值最大(RR=1.022,95% CI:1.017~1.027),气压为1 030.0 hpa滞后d 5时RR值最大(RR=1.054,95% CI:0.988~1.124);日照时数为7.0 h/d,滞后d 5时RR值最大(RR=1.017,95% CI:1.009~1.025);极高温、极高压、极低温和极低湿度对HFMD发病也有明显滞后效应。 结论 南宁市HFMD发病与气象因素相关,可利用气象因素预测HFMD发展趋势。 Abstract:Objective This study aims to investigate the influence and lag effects of meteorological factors on the incidence of hand-foot-mouth disease disease (HFMD). Methods Daily HFMD incidence data and concurrent meteorological data from 2010 to 2019 were collected and analyzed. The distributed lag non-linear model (DLNM) was utilized to examine the correlation between HFMD incidence and meteorological factors in Nanning. Results From 2010 to 2019, a total of 508 984 HFMD cases were reported in Nanning, with primary peaks observed from April to June and secondary peaks from September to October. The incidence rate for males to females was 1.57∶1, primarily among nursery-aged and home-based children. HFMD incidence exhibited a positive correlation with average temperature, relative humidity, and sunshine duration, and a negative correlation with atmospheric pressure. At 35.0 ℃, the mean temperature exhibited the highest RR value on the 9th day (RR=1.058, 95% CI: 1.037-1.079); At 86.0%, the relative humidity peaked on the 14th day (RR=1.011, 95% CI: 1.007-1.014); Atmospheric pressure displayed a "double peak" phenomenon, with the highest RR value at 990.0 hPa on the 7th day (RR=1.022, 95% CI: 1.017-1.027), and at 1 030.0 hPa on the 5th day (RR=1.054, 95% CI: 0.988-1.124); At 7.0 h/d, the sunshine duration revealed the maximum RR value on the 5th lag day (RR=1.017, 95% CI: 1.009-1.025). Notably, extreme heat, high-pressure, cold, and dry effects also demonstrated a significant lag effect on the onset of HFMD. Conclusions HFMD presents a severe epidemic situation in Nanning. The incidence of HFMD is significantly associated with meteorological factors. Meteorological factors can be leveraged to predict the disease′s development trend. -
