ObjectiveTo investigate the influence of various weather parameters on the risk of developing a low back pain (LBP) episode.DesignCase-crossover study.SettingPrimary care clinics in Sydney, Australia.Subjects981 participants with a new episode of acute LBP.MethodsWeather parameters were obtained from the Australian Bureau of Meteorology. Odds ratios (OR) and 95% confidence intervals (95% CI) were derived comparing two exposure variables in the case window-(1) the average of the weather variable for the day prior to pain onset and (2) the change in the weather variable from 2 days prior to 1 day prior to pain onset-with exposures in two control windows (1 week and 1 month before the case window).ResultsThe weather parameters of precipitation, humidity, wind speed, wind gust, wind direction, and air pressure were not associated with the onset of acute LBP. For one of the four analyses, higher temperature slightly increased the odds of pain onset.ConclusionsCommon weather parameters that had been previously linked to musculoskeletal pain, such as precipitation, humidity, wind speed, wind gust, wind direction, and air pressure, do not increase the risk of onset for LBP.© 2016 American Academy of Pain Medicine.
