Description:	Urban air pollution is a growing problem in developing countries. World Health Organization (WHO) in 2016 reported that more than 80% of urban areas have air pollution levels exceeding their limits. Calculating the health impacts of urban air pollution is an important step in air quality management, but is often made difficult by limited studies. A study was conducted to estimate the relative risk (RR) of air pollutants with cardiovascular and respiratory hospitalization and emergency room visits at Hospital Canselor Tuanku Muhriz (HCTM), Kuala Lumpur. Daily hospital admissions in 2010- 2014, and emergency room visits in 2013 were obtained from HCTM. Daily mean concentrations of particulate matter (PM10), sulfur dioxide (SO2), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) (daily max and 8-h average), and meteorological parameters were obtained from the Department of Environment (DOE) Malaysia. We examined the associations between daily levels of pollutants and cardiovascular and respiratory cases in HCTM using GAM model based on poisson regression, while controlling for time-trends, meteorological factors and holiday indicator. Effects for every 10 μg/m3 increment in pollutants were reported as RR on current-day (lag 0) to after five days (lag 5) exposure. The results showed that the highest risk found was with SO2 at lag 4 for respiratory admissions (RR = 1.123, 95% CI = 1.045-1.207), followed by NO2 at lag 5 for cardiovascular admissions (RR = 1.025, 95% CI = 1.005-1.046). PM10 and CO showed the highest risk to respiratory and cardiovascular emergencies at lag 0 (RR = 1.0128, 95% CI = 1.003-1.023) and lag 1 (RR = 0.998, 95% CI = 0.996-0.999) respectively. Gaseous pollutants showed significantly higher risks for cardiovascular and respiratory hospitalizations while PM10 showed significantly higher risks for respiratory emergency. In conclusion, urban air pollution showed both immediate and delayed effects for cardiovascular and respiratory hospitalizations and emergency room visits in HCTM from exposure to criteria pollutants.,Sarjana Sains Kesihatan
