Association of short-term exposure to sulphur dioxide and nitrogen dioxide with number of hypertensions in East Java, Indonesia

Abstract

Previously, several studies conducted related to hypertension which associated with sulphur dioxide and nitrogen dioxide. The number of East Java's hypertension cases from 2015 to 2017 had increased. It is predicted that the number of hypertension cases would be increased. This study was aimed to determine the association between short term exposure to sulphur dioxide and nitrogen dioxide with the number of hypertension cases in East Java. This research was an ecological study, where ambient air pollutants data were taken from the Environmental Management Information Report of East Java 2017, while the number of hypertension cases was taken from the report of Health Profile of East Java Province 2017. Spearman coefficient correlation was used to determine the objective. There was no association between sulphur dioxide with the number of hypertension cases according to gender (male: p= 0.624, r=-0.082; female: p= 0.697, r=-0.065; all cases: p= 0.768, r=-0.050) and nitrogen dioxide (male: p= at 0.24, r= 0.195; female: p= 0.611, r= 0.085; all cases: p= at 0.254, r= 0.190). There was an increase in the number of East Java hypertension cases. However, there was no association between SO2 and NO2 with the number of East Java hypertension cases.
