We estimated that in women who, on average, smoke a daily number of five cigarettes throughout pregnancy, 81% of the total risk of extremely preterm birth and 67% of the total risk of SGA outcome can be attributed to tobacco smoke exposure.
To investigate whether the differential expression of these miRNAs can be attributed to cigarette smoke and lung cancer, we confirmed their expression with qRT-PCR in an independent sample set, consisting of 30 individual serum samples from each group (nonsmoking controls, smokers, and the lung-cancer patients).
Then they used data on the health effects of smoke-related PM2.5 to estimate how many deaths could be attributed to landscape fire smoke.
The Pueblo study, however, did not assess what portion of the observed decrease in hospitalizations could be attributed to reduced secondhand smoke exposure among nonsmokers or to quitting among smokers.
In a 2011 study, conducted in partnership with researchers at the University of California at Berkeley and the University of California at San Francisco, Knowlton found that more than 760,000 encounters with the health system between 2000 and 2009 could be attributed to exposure to wildfire smoke.
Based on these results, the researchers estimated that about 1 in 3 cases of ADHD could be attributed to either prenatal tobacco smoke exposure or childhood lead exposure.
The apparent lack of effect of the studies could be attributed to the use of black smokes [ 17, 24– 26] and PM13 [ 27] instead of PM10 in their study.
Consequently, the difference between our results and earlier data on particulate size of cigarette smoke may be attributed to the type of tobacco, tobacco aging processes, and the adsorbent used.
