COVID-19 pandemic modifies temperature and heat-related illness ambulance transport association in Japan: a nationwide observational study

Abstract: Background During the COVID-19 pandemic, several illnesses were reduced. In Japan, heat-related illnesses were reduced by 22% compared to pre-pandemic period. However, it is uncertain as to what has led to this reduction. Here, we model the association of maximum temperature and heat-related illnesses in the 47 Japanese prefectures. We specifically examined how the exposure and lag associations varied before and during the pandemic. Methods We obta… Show more

“…Recently, as a result of the coronavirus disease 2019 (COVID-19) pandemic, increasingly more time has been spent at home. In Japan, the time people spend indoors increased by 13.8% from before the COVID-19 pandemic [ 43 ]. There is growing concern regarding indoor air quality (IAQ) worldwide, with some studies suggesting that IAQ worsens with increased time at home due to the COVID-19 pandemic [ 44 ].…”

“…A natural cubic spline function was applied to the temperature variable with 1 internal knot. For the lag dimension, we specified a lag period of 1 for HIAT 31 and mortality, 32 to capture possible delayed effects of heat exposure. The average of lag 0 to 1 was used.…”
