Determinant Factors Causing Symptoms Of Respiratory Disorders With Exposure To Nitrogen Dioxide In Adults Around The Steel Industry

Air pollution is a health problem that causes many deaths. The respiratory disorder is one of the causes of death due to increased air pollution in the environment. One of the gases that damage the environment is nitrogen dioxide (N0₂). N0₂can be produced from the combustion process, one of which is the result of combustion in the steel industry. This study was conducted to determine the relationship of factors that influence the respiratory disorders that occur in adults around the steel industry. Variable respiratory disorders, the concentration of N0₂, length of stay, BMI and a history of respiratory disease were tested using the Chi-square test with a p-value<0.05. Respiratory disorders have a significant relationship with a history of respiratory disorders having OR (95% CD value of 3.69 (1.548 - 8.799). Although it turns out that the N0₂concentration variable does not have a significant relationship with respiratory disorders with OR (95% CD value of 0.765 (0.329-1.779), other than that, the unrelated variable, is the variable length of stay having OR (95% CD value of 1.179 (0.523 - 2.655), BMI having OR (95% CD value of 1.739 (0.754 - 4.01). In this study, it was found that a factor that can cause the respiratory disorder is a history of respiratory disorders in adults.
