| Research Abstract |
To evaluate the impact of ambient temperature on morbidity, weconducted a time-series analysis by using the daily data of emergency ambulance dispatches for people aged 65 or older from 2006 to 2010 in Okayama city. After adjusting for a variety of covariates including suspended particulate matter and ozone, we found that an adjusted rate ratio for respiratory diseases (particularly, pneumonia and influenza) increased under heat environment. By contrast, an adjusted rate ratio for cardiovascular diseases (particularly, transient ischemic attack) increased under cold environment.
