“…Development and birth defects: Foeti of mothers who smoked during pregnancy were recorded to have reduced foetal measurements including head size, femur length, foetal weight and transcerebellar diameter [34,35,37]. Exposure to tobacco during pregnancy has consistently been reported to result in low birth weight (LBW) [42][43][44][45][46].…”

The aim of this review of reviews was to collate the latest evidence from systematic reviews about the maternal and child health outcomes of being exposed to tobacco and nicotine during pregnancy; the effectiveness of interventions designed to reduce these exposures, and barriers to and facilitators of smoking cessation during pregnancy. Two databases were searched to obtain systematic reviews published from 2010 to 2019. Pertinent data from 76 articles were summarized using a narrative synthesis (PROSPERO reference: CRD42018085896). Exposure to smoke or tobacco in other forms during pregnancy is associated with an increased risk of obstetric complications and adverse health outcomes for children exposed in-utero. Counselling interventions are modestly effective, while incentive-based interventions appear to substantially increase smoking cessation. Nicotine replacement therapy is effective during pregnancy but the evidence is not conclusive. Predictors and barriers to smoking cessation in pregnancy are also discussed. Smoking during pregnancy poses substantial risk to mother’s and child’s health. Psychosocial interventions and nicotine replacement therapy (NRT) appear to be effective in helping pregnant women quit smoking. Barriers to smoking cessation must be identified and steps taken to eradicate them in order to reduce smoking among pregnant women. More research is needed on smoking cessation medications and e-cigarettes.

“…data not shown) or were not original research articles, these were also excluded 23 . As the effect of maternal smoking in the prenatal period on the growth of the offspring has been reviewed thoroughly elsewhere 13,14 , the aim of the present review was to emphasize SHS exposure from other people smoking (i.e. paternal smoking).…”

“…To date, limited information has been collated to illustrate the association between SHS exposure in non-smoking mothers during pregnancy and/or in children during postnatal life and the growth of children. Two review studies examined the association between SHS exposure and children growth outcomes, focusing on tobacco use of the mother during pregnancy 13,14 . Two other review articles explored the impact of SHS exposure on non-smoking pregnant women on anthropometric growth of children, focusing on the newborn baby 15,16 .…”

INTRODUCTION The strong relation between maternal smoking and maternal secondhand smoke (SHS) exposure and the growth of newborn infants has been proven. However, the effect of SHS on growth outcomes of older children is not well defined. Through a systematic literature review, we sought to determine whether a relationship exists between SHS exposure and growth outcomes of children up to 8 years of age. METHODS A systematic review was performed, including articles published between 2004-2019, related to SHS exposure (prenatal and postnatal) and children's growth (weight, length/height, and head circumference). The relevant articles were identified from Science Direct, ProQuest, Sage Publication, Scopus, Wiley Online Library, CINAHL Plus with Full Text (via EBSCOhost) and Google search. RESULTS Seventeen articles were identified, of which three categories of growth measurements were extracted, comprising weight (weight, WAZ, WHZ, and BMI), height (height/length and HAZ) and head circumference. SHS exposure both pre or postnatally was inversely associated with weight (deficit in weight, risk of underweight, risk of wasting) and height (lower length and risk of stunting) and elevated BMI of children. Furthermore, prenatal SHS exposure was associated with a lower head circumference. CONCLUSIONS The current review identified that exposure to SHS may be associated with adverse growth outcomes in children. It is crucial that active smokers, specifically those who live with children or with a pregnant partner, are made aware of the potential effects of SHS exposure on non-smokers. Further assessment of the association between exposure to SHS and other growth outcomes in other age groups is needed.

“…In the context of this study, it could be that earlier healthcare encounters were less able to identify IUGR and only noted growth de cits at or after birth. As well, given that smoking is well known to in uence fetal growth 30,31 and 29.7% of the women in the study who used alcohol also had concurrent tobacco use compared to only 5.7% of women with no alcohol use; therefore, it is possible that patterns of smoking affected or confounded growth results. Regardless, outcomes from this study suggest that even when growth de cits are not identi ed early in the pregnancy, primary care providers may wish to consider increased monitoring of fetus development in mothers who are believed to be tobacco and/or alcohol users.…”

BackgroundThe current study aimed to estimate the prevalence of alcohol use identified as a risk factor during pregnancies by the antenatal care providers, resulting in live births in British Columbia (BC) and to examine associations between alcohol use, adverse neonatal outcomes, and pregnancy complications.MethodsThis population-based cross-sectional study utilized linked obstetrical and neonatal records within the BC Perinatal Data Registry (BCDPR), for deliveries that were discharged between January 1, 2015 and March 31, 2018. The main outcome measures were alcohol use identified as a risk factor during pregnancy, associated maternal characteristics, pregnancy complications, and adverse neonatal outcomes. Estimates for the period and fiscal year prevalence were calculated. Chi-square tests were used to compare adverse neonatal outcomes and pregnancy complications by alcohol use during pregnancy. Logistic regression was used to examine the association between alcohol use during pregnancy and adverse neonatal outcomes and pregnancy complications, after adjusting for identified risk factors.ResultsA total of 144,779 linked records within the BCDPR were examined. The period prevalence of alcohol use during pregnancy identified as a risk factor was estimated to be 1.1% and yearly prevalence was 1.1%, 1.1%, 1.3% and 0.9% from the 2014/2015 fiscal year to 2017/2018, respectively. Indicated alcohol use was associated with younger maternal age, fewer antenatal visits, being nulliparous, a history of mental illness, substance use and smoking. Alcohol-exposed neonates had greater odds of being diagnosed with low birth weight (aOR = 1.25; 95% CI: 1.01, 1.53), other respiration distress of newborn (aOR = 2.57; 95% CI: 1.52, 4.07), neonatal difficulty in breastfeeding (aOR = 1.97; 95% CI: 1.27, 2.92) and unspecified feeding problems (aOR = 2.06; 95% CI: 1.31, 3.09)ConclusionsThe prevalence of alcohol use during pregnancy identified as a risk factor, estimated in this study, was comparable to the previous estimates within BCDPR. Prenatal alcohol exposure was associated with notable differences in maternal and neonatal characteristics and adverse neonatal outcomes. More consistent and thorough screening and prevention efforts targeting alcohol use in pregnancy are urgently needed in Canada.
