Dust Phenomenon Affects on Cardiovascular and Respiratory Hospitalizations and Mortality " A Case Study in Kermanshah, during March-September 2010-2011

Dust phenomenon has adverse effects on the health of the population. Due to the increasing concentration of Kermanshah dust phenomenon in recent years، The aim of this study was to measure the concentration of the sensitivity coefficients between dust phenomenon hospitalization and mortality rates for heart and respiratory. This was a descriptive study in which we studied the sensitivity coefficient of hospitalization and mortality rates for heart disease and respiratory to changes of dust concentration.. The study duration was during March-September 2010 and 2011. We collected the dust phenomenon data from Kermanshah Province Environmental Protection Department. The admissions and mortality of the cardiovascular and respiratory sufferers was collected from the Imam Ali، Imam Reza، and Imam Khomeini governmental hosiptals in Kermanshah. 1% increase in air pollution caused by the dust phenomenon will result in increasing about 0. 5 % of the respiratory patients، 1% cardiac patients، and about 0. 3% of the heart disease mortality. The relationship between dust phenomenon and respiratory sufferers was statistically not significant. We found that respiratory and cardiovascular hospital admission has a high sensitivity to dust phenomenon. This sensitivity has increased from 2010 to 2011. This sensitivity was greater for males than females. At least، during March-September 2010، for every 100% increase in the concentration of dust phenomenon، cardiovascular mortality increased by 29%. ject classid= «clsid: 38481807-CA0E-42D2-BF39-B33AF135CC4D» id=ieooui>
