To quantitatively evaluate the influences of daily temperature on emergency department visits for the abdominal pain, the emergency department visits data from medical records from January 2009 to December 2012 were collected in a general hospital of Haidian District, Beijing City. The data on the meteorological factors and the air pollutants (SO2, NO2 and PM10) at the same time periods were also collected from the local authorities of Beijing. Generalized additive models were used to explore the exposure-response relationship between the average daily air temperature, maximum temperature, minimum temperature, diurnal temperature range (DTR), variable temperature in 24 h and abdominal pain emergency department visit number. All of the different air temperature indicators had positive relationships with emergency department visits for abdominal pain complaints. With every 1?C decrease in the average daily temperature, maximum temperature and minimum temperature, the relative risks of daily emergency department visits for abdominal pain would increased by 1.005 2(95%CI:1.003 4～1.007 0), 1.004 9 (95%CI:1.003 2～1.006 6) and 1.0047 (95%CI:1.002 9～1.006 5). The effects of DTR and 24-hour diurnal temperature variations on the emergency department visits showed no statistical significance. The abdominal pain emergency department visits were the most in summer, and the average daily temperature, maximum temperature and minimum temperature had an adverse effect on daily emergency department visits for abdominal pain.
