As Temperatures Increase, So Do AD Office Visits

Int J Dermatol, ePub 2018 Nov 11; Fleischer

Increased temperatures predict increased likelihood of atopic dermatitis (AD) office visits, according to a recent study. US region‐specific satellite‐derived data air temperature from the North America Land Data Assimilation System from 1993 to 2011 were studied in relation with ambulatory AD visits to all physicians from the National Ambulatory Medical Care Survey. Researchers found:

  • During the 19‐year study period, in no regional location in the US is there clear evidence of a winter flare of AD.
  • The greatest number of visits occur in May and June, and smaller peaks also occur in January and October.
  • As the ambient air temperature increases, the likelihood of an AD visit rises.
  • In the South, the hottest US climate, summer is responsible for substantially more AD visits.
  • In every other region and in the US overall, the largest number of AD visits occur in spring.
  • AD visits appear to display regional variation in comparing the Northeast, South, Midwest, and West.
