Core Tip

Core Tip: The model showed correlation between five meteorological factors and air pollutants and gastroesophageal reflux disease (GERD)-related medical utilization. S- and inverted U-shaped changes were noted in average temperature and air pollutants. Average temperature, sunshine duration, wind speed, PM2.5, and carbon monoxide are risk factors of GERD. GERD occurrence is reduced using environmental management and national alarm systems.
