Both cigarette and e-cigarette exposed infants had a significantly greater number of abnormal reflexes
Cigarettes: P = 0.001
E-cigarettes: P = 0.002
Compared to non-exposure, cigarette exposed infants performed significantly worse for
Self-regulation: P = 0.010
Motor maturity: P = 0.002
Compared to non-exposure, e-cigarette exposed infants also had decreased motor maturity, but only marginally worse self-regulation (not-significant)
Self-regulation: P = 0.057
Motor maturity: P = 0.036
Compared with non-exposure, cigarette exposed infants had significantly
Lower birthweight: P = 0.021
Reduced head circumference: P = 0.008
However, compared with non-exposure, e-cigarette exposed infants had no difference in
Infants exposed to e-cigarettes prenatally do not appear to have worse birth outcomes than non-exposed infants
However, exposed children do have abnormal primitive reflexes and marginally decreased self-regulation abilities
The authors conclude
This is the first study assessing neurobehavioural outcomes associated with prenatal nicotine exposure through cigarettes or e-cigarettes at one month old
…the present findings indicate that there could be harm associated with e-cigarette use and therefore the ultimate aim must be to stop smoking, without the use of e-cigarettes. Indeed, caution should probably be applied to all NRT products
Given the predictive nature of newborn assessments, in particular the NBAS, the notion that nicotine by itself is relatively harmless, is a concept that needs to be further questioned and further investigated
