Abstract

The relationships between the exposure of pollutants towards hospitalized admission and mortality have been identified in several studies on Asian cities such as Taipei, Bangkok and Tokyo. In Malaysia, evidence on the health risks associated with exposure to pollutants is limited. In this study, daily time-series data were analysed to estimate risks of cardiovascular and respiratory hospitalized admissions associated with particulate matter ≤ 10 μm (PM10), carbon monoxide (CO), nitrogen dioxide, sulphur dioxide, and ozone concentrations in Klang Valley during 2004-2009. Daily counts of hospital admissions for cardiovascular and respiratory outcomes were obtained from eleven hospitals while pollutants data were taken from several air quality monitoring stations located nearest to the hospitals. These data were fitted with Generalised Additive Poisson regression models. Additionally, temperature, humidity, and time data were also included to allow for potential effect of weather and time-varying influences on hospital admissions. CO showed the most significant (P < 0.05) relationship to cardiovascular admissions. An increment of 1 ppm in CO predicted an increase of 4% to 20% in cardiovascular admissions. Respiratory admissions were associated with PM10, which had about 1% increase in risk of admission per 10 ug/m3 increment in PM10. Exposure to CO and PM10 increases the risk of hospitalization for cardiovascular and respiratory illnesses in Klang Valley, Malaysia.
