Sun S, et al. - Researchers evaluated the association of intraseasonal temperature variability with respiratory disease hospitalizations in a prospective Chinese elderly cohort of 66,820 older people (≥65 years) with 10–13 years of follow-up. Seasonal temperature variability was defined as the SD of daily mean summer (June–August) or winter (December–February) temperatures. Of 12,689 cases of incident respiratory diseases, 6672 suffered pneumonia and 3075 COPD. Wintertime temperature variability was shown to be related to higher risk of incident respiratory diseases. No statistically significant associations were observed for summertime temperature variability.
