Effect of Exposure to 2.5 μm Indoor Particulate Matter on Adult Lung Function in Jakarta

OBJECTIVES: Lung function impairment due to exposure to indoor air pollution of particulate matter size 2.5 micrometers (PM(2.5)) is not well documented in Jakarta. METHODS: To assess whether there is an association between indoor PM(2.5) concentration and lung function impairment among the adult population, a cross-sectional design was implemented. There were 109 adults selected aged between 20 years and 65 years from the Pulo Gadung industrial area, East Jakarta. Association and logistic regression analysis were implemented for statistical analysis of the data. RESULTS: The average exposure to indoor PM(2.5) was 308 μg/m(3). There were 38.5% of participants that had lung function impairment. PM(2.5) concentration was found to be associated with lung function impairment among the adult population living in Pulo Gadung industrial area after controlling for gender, duration of exposure, ventilation, smoking status, and humidity. CONCLUSION: The results of this study suggest that PM(2.5) concentrations in the Pulo Gadung industrial area may be the main contributor to the impairment of lung function for adults living in the surrounding residential area.
