Research description

My PhD project aims to investigate total mortality, specific mortality, and susceptible subgroups in relation to short-term exposure to air pollution. The project further aims to assess the short-term effects of air pollution on out-of-hospital cardiac arrest and investigate potential effect modifying factors.

Air pollution has been associated with detrimental effects on human health by many epidemiological studies. Most of these studies have focused on total mortality or cardiorespiratory mortality and some have investigated associations with cardiorespiratory morbidity. There is a knowledge gap concerning susceptible subgroups to air pollution related mortality in the community.  There are suggestions that some population sub-groups such as the elderly, infants and patients with underlying disease are more vulnerable to the effects of air pollution, however, evidence confirming this is limited.

Out-of-hospital cardiac arrest (OHCA) is a leading cause of death in the United States and Europe with low survival rate. In Sweden about 5-10,000 OHCAs occur each year with 14-16% surviving to one month. Few studies have investigated whether air pollution triggers cardiac arrest with inconsistent results.
