Estimating the Incidence Rate Ratio of Hand Foot Mouth Diseases with Meteorological Factors in Maha Sarakham Province
Keywords:
Hand foot mouth disease, Humidity, Incidence rate ratio, Rainfall volumeAbstract
This study aimed to estimate the incidence rate ratio of hand foot mouth diseases (HFMD) with meteorological factors in Maha Sarakham province. It was the correlational research. Data collected from the number of monthly hand foot mouth diseases’ patients from Bureau of Epidemiology and the meteorological data from Upper Northeastern Meteorological Center. The data were analyzed by descriptive statistics, correlation coefficients, and the generalized linear regression. The results showed that the number of monthly HFMD patients was related to monthly average rainfall and monthly average humidity (Pearson correlation coefficient (p-value <.05) (r=0.366, 0=363)), which was considered to be at a fair level of relationship (0.3-0.5 Fair). When rainfall volume was an independent variable, the generalized Poisson regression model (p-value <.05) (IRR = 1.15 ; 95%CI : 1.04, 1.27) with the coefficient of determination (R2) of 0.205, which can be used to establish preventive measures for HFMD infection in the area based on monthly rainfall from weather forecasts in advance.
