A Study on Factors Related with Regional Occurrence of Cardiac Arrest Using Geographically Weighted Regression

Abstract

This study sought to use the ecological study design and geographically weighted regression(GWR) to identify regional factors regarding the occurrence of cardiac arrest and to investigate the utility of GWR. Our data came from two main sources: 2009 Out-of-Hospital Cardiac Arrest Surveillance and Community Health Survey. As the result, risk factors on cardiac arrest are moderate-intensity physical activity, obesity rate, diagnosis rates of hypertension and diabetes mellitus which generally increase incidences of cardiac arrest. Our finding showed that GWR increased goodness-of-fit of model in comparison with traditional OLS regression. Considering the usefulness of ecological studies and GWR, methods of this study will help policymakers in terms of planning health programs and identifying priority regions for prevention of cardiac arrest.
