Application of disability adjusted life years in evaluating health effects due to particulate air pollution in Chinese cities / 中华预防医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the loss of disability adjusted life years (DALYs) due to particulate air pollution in Chinese urban residents.</p><p><b>METHODS</b>DALYs was applied to evaluate the health effects due to particulate air pollution in the residents of 656 Chinese cities, and the data of annual average concentrations of inhalable particle (PM(10)) in 2006 were collected from the state-owned air quality monitoring network.</p><p><b>RESULTS</b>Particulate air pollution in Chinese urban areas in 2006, could cause (506.6 +/- 95.2) thousand premature deaths, (156.6 +/- 41.2) thousand new cases of chronic bronchitis, (12.6 +/- 5.2) million outpatient visits for internal medicine, (99.9 +/- 50.4) thousand and (72.0 +/- 8.2) thousand hospital admissions for cardiovascular diseases and respiratory diseases respectively. The attributable DALYs loss in urban residents amounted up to (5.26 +/- 0.99) million person years in 2006, of which, 96.26% (506.55/526.22) were caused by premature deaths. The attributable loss of DALYs increased with more seriously PM-polluted atmosphere and larger urban population.</p><p><b>CONCLUSION</b>Substantial adverse health effects due to outdoor particulate air pollution were observed in China urban areas, thus strengthening air pollution control still remains an imperative and urgent matter in public health perspective.</p>
