Particulate air pollution on cardiovascular mortality in the tropics: impact on the elderly.


ABSTRACT: BACKGROUND:Air pollution has a significant health impact. Most data originate from temperate regions. We aim to study the health impact of air pollution, particularly among the elderly, in a tropical region. METHODS:A daily time-series analysis was performed to estimate excess risk (ER) of various air pollutants on daily death counts amongst the general population in Singapore from 2001 to 2013. Air pollutants included particulate matters smaller than 10??m, and 2.5??m (PM10, PM2.5), carbon monoxide (CO), nitrogen dioxide (NO2), ozone (O3) and sulphur dioxide (SO2). The studied outcomes were non-accidental and cardiovascular mortality. Single-day lag and distributed lag models were studied and adjusted for confounders. RESULTS:In single-day lag models, a 10??g/m3 increase in particulate matter was associated with significant increases in non-accidental (PM10 ER: 0.627%; 95% confidence interval (CI): 0.260-0.995% and PM2.5 ER: 0.660%; 95% CI: 0.204-1.118%) and cardiovascular mortality (PM10 ER: 0.897; 95% CI: 0.283-1.516 and PM2.5 ER: 0.883%; 95% CI: 0.121-1.621%). This was significant in the elderly ??65?years but not in those
