Li J, Yu T, Javed I, et al. - This study was sought to assess if meteorological factors (temperature, barometric pressure, relative humidity, ultraviolet index, and seasons) trigger flares in male and female urologic chronic pelvic pain patients. Flare status every 2 weeks was evaluated in this case‐crossover study of flare triggers in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain 1‐year longitudinal study. Researchers analyzed flare symptoms, flare start date, and exposures in the 3 days preceding a flare or the date of questionnaire completion for the first three flares and at three randomly selected nonflare times. Via Poisson regression, variations in flare rates by astronomical and growing seasons were analyzed. They included a sum of 574 flare and 792 nonflare assessments (290 participants) in the case‐crossover analysis. Minimal evidence was found to suggest that weather triggers flares, although we cannot rule out the possibility that a small subset of patients is susceptible.
