Abstract

The World Health Organization estimates that more than 2 million premature deaths annually can be attributed to air pollution with more than half occurring in developing countries. The relationship between cough frequency among Grade 1 pupils and and the levels of air pollutants in Cagayan de Oro was explored in the study. Frequency of cough was determined through a questionnaire and data on the levels of air pollutants particularly ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2), benzene (ben) and toluene (tol) were taken from DENR. The t-test and chi-square were used to determine any significant difference in the variable studies. Findings reveal a significant difference in the levels of air pollutants, except ozone, between November 2011 and January 2012. However, no significant difference existed in the frequencies of cough between late November to early December 2011 and the last week of January  to early February 2012. Overall correlation between air pollutant levels  and cough frequency  distribution was not established in this study. The findings imply that the levels of air pollutants in the city have not yet reached  a level at which a significant effect on health, especially respiratory health, could be observed.

Objectives

The study aimed at determining the relationship between cough frequency among Grade 1 pupils and the levels of air pollutants in Cagayan de Oro City. Specifically, the study sought to achieve the following objectives:


a) To determine the levels of sulfur dioxide, nitrogen dioxide, ozone benzene and toluene in the city during November 2011 and January 2012.


b) To determine the frequency of cough among Grade 1 pupils in selected elementary schools in the city during November 2011 and January 2012; and


c) To determine if there is a relationship between the levels of of the air pollutants and frequency of cough among Grade 1 pupils.
