Effects of Air Pollution on the Spirometric Findings of Filipino School Children: A Challenge to the Clean Air Act
Ma. Donna Divina L. Briones MD, Section of Pulmonology, Philippine Children’s Medical Center

Abstract

To determine the effects of air pollution on the lung function of Filipino school children exposed to high and low concentration of total suspended particles (TSP)24-hour sampling average for 3 years (1996-1998) we studied 200 school children coming from two zones, Zone 1 with low or fair TSP (130.67 ug/Ncm) and Zone 2 with high or poor TSP (258.67 ug/Ncm). All the parents/guardians of the participating school children answered questionnaires regarding their history and respiratory symptomatology. These school children underwent physical examination and pulmonary function testing (baseline, post-bronchodilator, exercise challenge testing) and indices were compared between the two zones.

History of allergy, nasal congestion, parental atopy, use of gas in cooking and walking as a means of going to school was significantly higher among those in Zone 2 while sneezing, and transportation as a means of going to school were significantly higher among those in Zone 1. There was a significantly lower mean values in the baseline FEV1, FVC and MMEF and a higher percent change in MMEF observed among school children from Zone 2 than Zone 1. Postbronchodilator percent change ( CFEV1, CPEFR) and the exercise challenge tests (EXFEV1, EXPEFR) results showed no statistically significant differences between the two zones. Within each group, there were more school children in Zone 2 with a significant increase in MMEF post-bronchodilator. This study shows that school children exposed to a higher level of air pollution (258.67 ug/Ncm/24 hours TSP) have lower baseline spirometric findings and evidence of increased airway hyperresponsiveness post-bronchodilator. The Clean Air Act may assist the government in its efforts to achieve a healthier environment and a cleaner air for our children to breathe but there is yet a need for a more intensive information and education campaign and a comprehensive, accurate and current emission inventory to provide a sound basis for air quality planning and control measures.
