en Analysis of out-of-hospital cardiac arrest and ozone pollution: A qualitative study عمومى General مقاله مروری Review Article <div style="text-align: justify;">Background: Air pollution is increasingly associated with cardiovascular events. As for ozone (O3) pollution, results are inconsistent though O3 levels are associated with hospital admissions, global mortality, and respiratory, and cardiovascular mortality. Methods: In this time-stratified case-crossover study, the associations between short-term exposure to O3 (on an hourly and daily scale) and out-of-hospital cardiac arrests (OHCA) were investigated. Specific subgroups were explored by sex, age, diabetes status, for OHCA during non-holiday periods. Data were collected in the Nord-Pas-de-Calais region, France, in 2015. Data were statistically analyzed using conditional logistic regression (CLR). Results: The study included 1039 cases of OHCA. Significant negative associations were found between OHCA and O3 levels measured in 3 or 4 days before the arrest for all the people, and 1, 2 or 3 days before the arrest for men. As for OHCA during non-holiday periods, there was no significant negative associations but a positive association was revealed for women between OHCA and O3 levels measured in 5 days before the arrest (OR=1.53, P = 0.008). Conclusion: According to the results, OHCA should be investigated during non-holiday periods to control potential confounders that would lead to negative associations. Women might be a susceptible subgroup to O3 pollution.</div> Heart arrest, Ozone, Air pollution, Epidemiology, Environmental health 283 289 http://ehemj.com/browse.php?a_code=A-10-1-154&slc_lang=en&sid=1 Marie Albert mariealbert1@hotmail.fr 10031947532846005843 10031947532846005843 Yes Corresponding author: Public Health Department, Faculty of Medicine, Univ.
