How prenatal exposures shape the infant brain: Insights from infant neuroimaging studies
2021, Neuroscience and Biobehavioral ReviewsAssociation between maternal active smoking during pregnancy and placental weight: The Japan environment and Children's study
2020, PlacentaCitation Excerpt :Moreover, there is no indication to believe that the distribution of trimmed and untrimmed placentas in our study sample will bias toward the association found in our study between maternal smoking and a heavy placenta or a high PW/BW ratio. Second, we relied on self-reported maternal smoking status information, which might be under-reported [26]. However, past studies have reported a high correlation between the self-reported number of cigarettes and nicotine level of hair, urinary cotinine level, or carboxyhemoglobin concentration suggesting that self-reported smoking during pregnancy can be used as a reliable measurement [27–29].
Impact of maternal smoking associated lyso-phosphatidylcholine 20:3 on offspring brain development
2020, Journal of Steroid Biochemistry and Molecular BiologyCitation Excerpt :One limitation of the present study is that maternal smoking status was based on a self-report. Previous studies have shown that pregnant mothers under-report smoking during pregnancy showing that between 7 and 22 % of the self-reported non-smokers were actually smokers according to blood and urine cotinine levels [32,33]. Since we had information about maternal smoking on a yes/no level, we are unable to figure out potential dose dependencies of the observed effects of maternal smoking.
Combined effects of AHR, CYP1A1, and XRCC1 genotypes and prenatal maternal smoking on infant birth size: Biomarker assessment in the Hokkaido Study
2016, Reproductive ToxicologyCitation Excerpt :Mothers who smoked during the third trimester more often had partners who smoked than did mothers who did not smoke (Table 1). Possibly, mothers who claimed to be non-smokers yet had high cotinine levels were not truthfully reporting their smoking status as shown in previous studies [53,54] or were strongly exposed to the smoke of partners, housemates, and/or co-workers. A total of 692 mothers reported smoking during their third trimester; of those 37 mothers had cotinine levels ≤11.48 ng/mL and categorized as non-smokers in this study (Table 2).
