The Impact of Ambient Temperature on Childhood HFMD Incidence in Inland and Coastal Area: A Two-City Study in Shandong Province, China.

Zhu L, Yuan Z, Wang X, Li J, Wang L, Liu Y, Xue F, Liu Y - Int J Environ Res Public Health (2015)

Bottom Line: A distributed lag non-linear model (DLNM) with Poisson distribution was used to examine the nonlinear lagged effects of daily mean temperature on HFMD incidence.After controlling potential confounders, temperature showed significant association with HFMD incidence and the two cities demonstrated different impact modes ( I2= 96.1%; p < 0.01).The results highlight the effect of temperature on HFMD incidence and the impact pattern may be modified by geographical localities.

ABSTRACT
Hand, foot and mouth disease (HFMD) has been a substantial burden throughout the Asia-Pacific countries over the past decades. For the purposes of disease prevention and climate change health impact assessment, it is important to understand the temperature-disease association for HFMD in different geographical locations. This study aims to assess the impact of temperature on HFMD incidence in an inland city and a coastal city and investigate the heterogeneity of temperature-disease associations. Daily morbidity data and meteorological variables of the study areas were collected for the period from 2007 to 2012. A total of 108,377 HFMD cases were included in this study. A distributed lag non-linear model (DLNM) with Poisson distribution was used to examine the nonlinear lagged effects of daily mean temperature on HFMD incidence. After controlling potential confounders, temperature showed significant association with HFMD incidence and the two cities demonstrated different impact modes ( I2= 96.1%; p < 0.01). The results highlight the effect of temperature on HFMD incidence and the impact pattern may be modified by geographical localities. Our findings can be a practical reference for the early warning and intervention strategies of HFMD.

Mentions: Figure 2 illustrates the daily distribution of HFMD incidence and mean temperature. The results indicate that the occurrence of HFMD presents significant seasonality in Jinan and Qingdao. It could be found that the incidence peak appeared in May and July in Jinan, and the epidemic peak in Qingdao was observed in July and June during the study periods.
