Climate Change and Diarrheal Disease Prevalence in Korea

Abstract

We analysed the outbreak of diarrheal disease due to climate change using 2004~2008 claim data from the National Health Insurance and Automatic Weather System data. Weather data were taken, including daily temperature and precipitation from 194 AWS managed by the Korea Meteorological Administration. We used a generalized estimation equation and a generalized linear model for a time-series of poisson distribution and considered the seasonal patterns of the disease and time lags to estimate the relationship between climate factor and the prevalence of diarrheal disease. The main results of the study were that mean prevalence rate of diarrheal disease was rising year by year during the study period and that there were positive associations between the prevalence of diarrheal disease reports and temperature. These results are consistent with the findings of previous research and suggest that climate change is likely to exacerbate diarrheal disease in Korea.
