Many long-term adverse effects of smoking during pregnancy are known. Increasingly, adverse effects in the grandchild after grandmaternal smoking during pregnancy are reported. We explored this in a birth cohort of 24,000 grandmother–mother–child triads identified from the Finnish Medical Birth Register in 1991–2016. Multiple logistic regression was used to analyze the association between any smoking during pregnancy by both grandmother and mother, or only grandmother or mother on adverse birth outcomes. No smoking by neither grandmother nor mother was used as the reference. As endpoints, preterm birth, low birth weight, small for gestational age (birth weight, birth length, head circumference), and body proportionality (low ponderal index, high brain-to-body ratio, high head-to-length ratio) were included. Smoking by both grandmother and mother was consistently associated with higher risks than smoking only by the mother. Birth length and weight were especially sensitive to (grand)maternal smoking. In conclusion, the combined effect of grandmaternal and maternal smoking is associated with higher risks than only maternal smoking.

Meconium samples collected from 115 neonates were analysed for nicotine, cotinine and trans -3-hydroxycotinine (OH-cotinine) by means of high-performance liquid chromatography (HPLC) to identify prenatal smoke exposure. The self-reported maternal smoking status during pregnancy was determined by means of a questionnaire and verified by measurements in urine prior to childbirth. The total sum of nicotine and its metabolites (Sumtot) of the first passed meconium samples was 1560 ± 1024 pmol/g in newborns of smoking mothers. Smoking of less than five cigarettes was clearly detected. Sumtot remained constant in all meconium samples passed by a neonate in succession. However, the proportion of nicotine decreased with the time of passage after birth and the OH-cotinine proportion increased, whereas cotinine hardly changed. Nicotine or its metabolites were not detectable in meconium (detection limit < 20 pmol/g), when the mothers were only exposed to environmental tobacco smoke (ETS) using the HPLC method. The hypothesis that the content of nicotine metabolites in meconium reflects long-term smoke exposure could not be confirmed in newborns whose mothers had quit smoking during the latter half of pregnancy. Determining Sumtot enables the intensity of continuous smoking during pregnancy to be estimated in all meconium samples passed by a newborn. Human & Experimental Toxicology (2007) 26: 535—544

Objectives: Maternal smoking during pregnancy is associated with a reduced risk of type 1 diabetes (T1D) in the offspring. We investigated whether this association is consistent with a causal interpretation by accounting for familial (shared genetic and environmental) factors using family-based, quasi-experimental designs. Design: A nationwide, prospective cohort study and a nested case-control study (quasi-experiment) comparing children with T1D to their age-matched siblings (or cousins). Setting: Swedish national registers. Participants: We included 2,995,321 children born in Sweden between 1983 and 2014. Exposure: Information on maternal smoking during pregnancy was retrieved from the Swedish Medical Birth Register. Main outcome measures: Children were followed for a diagnosis of T1D until 2020 through the National Patient, Diabetes and Prescribed Drug Registers. Results: A total of 18,617 children developed T1D, with a median age at diagnosis of 9.4 years. The sibling and cousin comparison design included 14,284 and 7,988 of these children, respectively. Maternal smoking during pregnancy was associated with a 22% lower risk of offspring T1D in the full cohort (hazard ratio: 0.78, 95% confidence interval [CI]: 0.75 to 0.82) in the multivariable-adjusted model. The corresponding odds ratio was 0.78 (95% CI: 0.69 to 0.88) in the sibling and 0.72 (95% CI: 0.66 to 0.79) in the cousin comparison analysis. Conclusions: This nationwide, family-based study provides support for a protective effect of maternal smoking on offspring T1D. Mechanistic studies are needed to elucidate the underlying pathways behind this link.

Abstract Background Small for gestational age (SGA) birth weight, a risk factor for infant mortality and delayed child development, is associated with maternal educational attainment. Maternal tobacco smoking during pregnancy could contribute to this association. We aimed to quantify the contribution of maternal smoking during pregnancy to social inequalities in child birth weight for gestational age (GA). Methods Data come from the French nation-wide ELFE cohort study, which included 17 155 singletons. Birth weights for GA were calculated using z-scores. Associations between maternal educational attainment, tobacco smoking during pregnancy and child birth weight for GA were ascertained using mediation analysis. Mediation analyses were also stratified by maternal pre-pregnancy body mass index. Results Low maternal educational attainment was associated with an increased odd of tobacco smoking during pregnancy [adjusted OR (ORa) = 2.58 (95% CI 2.34–2.84)] as well as a decrease in child birth weight for GA [RRa = 0.94 (95% CI 0.91–0.98)]. Tobacco smoking during pregnancy was associated with a decrease in offspring birth weight for GA [RRa = 0.73 (95% CI 0.70–0.76)]. Mediation analysis suggests that 39% of the effect of low maternal educational attainment on offspring birth weight for GA was mediated by smoking during pregnancy. A more important direct effect of maternal educational attainment on child birth weight for GA was observed among underweight women [RRa = 0.82 (95% CI 0.72–0.93)]. Conclusions The relationship between maternal educational attainment and child birth weight for GA is strongly mediated by smoking during pregnancy. Reducing maternal smoking could lessen the occurrence of infant SGA and decrease socioeconomic inequalities in birth weight for GA.

Maternal Smoking During Pregnancy

Maternal smoking during pregnancy is associated with both reduced birth weight and adverse neurobehavioral outcomes. The aim of this study was to investigate longitudinal associations between maternal smoking during pregnancy and childhood behavioral outcomes, and to determine the role of birth weight in mediating such associations. The study included 489 mother–child pairs. Prenatal exposures were assessed via maternal interviews conducted on average 1 year after delivery and child behavior assessments were completed at 5–12 years of age using the Child Behavior Checklist (CBCL) and Teacher Report Form (TRF). Maternal smoking during pregnancy was associated with externalizing and total behavior problems according to both mother and teacher report. Maternal smoking was also associated with the following percentage increases in scores: 41% (CBCL) and 44% (TRF) for aggressive behavior and 65% (CBCL) and 47% (TRF) for attention problems. Associations with behavior problems were attenuated or no longer observed for mothers that quit smoking in early pregnancy. The proportion of the total effect of maternal smoking on behavioral outcomes explained by differences in birth weight was small and ranged from 6.6% for externalizing behavior on the CBCL to 20.1% for rule-breaking behavior on the CBCL. Our results suggest that birth weight differences explain only a small proportion of the magnitude of association between maternal smoking during pregnancy and selected behavioral outcomes.

Cattle sired by Piedmontese or Wagyu bulls were bred and grown within pasture-based nutritional systems followed by feedlot finishing. Effects of low (mean 28.6 kg, n = 120) and high (38.8 kg, n = 120) birth weight followed by slow (mean 554 g/day, n = 119) or rapid (875 g/day, n = 121) growth to weaning on carcass, yield and beef quality characteristics at about 30 months of age were examined. Low birth weight calves weighed 56 kg less at 30 months of age, had 32 kg lighter carcasses, and yielded 18 kg less retail beef compared with high birth weight calves. Composition of carcasses differed little due to birth weight when adjusted to an equivalent carcass weight (380 kg). Calves grown slowly to weaning were 40 kg lighter at 30 months of age compared with those grown rapidly to weaning. They had 25 kg smaller carcasses which yielded 12 kg less retail beef than their counterparts at 30 months of age, although at an equivalent carcass weight yielded 5 kg more retail beef and had 5 kg less fat trim. Neither low birth weight nor slow growth to weaning had adverse effects on beef quality measurements. No interactions between sire-genotype and birth weight, or growth to weaning, were evident for carcass, yield and beef quality traits. Although restricted growth during fetal life or from birth to weaning resulted in smaller animals that yield less meat at about 30 months of age, adverse effects on composition due to increased fatness, or on indices of beef quality, were not evident at this age or when data were adjusted to an equivalent carcass weight.

Genetic And Environmental Factors

AbstractBirth weight is in large extent influenced by gestational age. In addition genetic and environmental factors determine intrauterine growth and birth weight. The contributions of these factors may be influenced by maternal smoking during pregnancy. We examined birth weight and maternal smoking in a sample of 2930 twin pairs from the Netherlands Twin Register using structural equation modelling. Gestational age accounted for 27–44% of the variance in birth weight. A lower variability of birth weight and a lower association of birth weight with gestational age was found in twins whose mothers smoked during pregnancy. The variance not associated with gestational age was independent of maternal smoking during pregnancy. A systematic smaller part of the variability in birth weight was associated with variability in gestational age in second born twins compared to first born twins. The heritability of interindividual differences in birth weight was modest (10% for twins with non-smoking mothers and 11% for twins with smoking mothers). Common environmental influences other than gestational age accounted for a slightly larger part of the variance not associated with gestational age (17–20%).

Maternal Smoking During Pregnancy

Since the first report by Simpson (1957) of the association between premature birth and maternal smoking, the research on the consequences of maternal smoking during pregnancy on perinatal outcome has been intense. Even if some of the findings have been contradictory, it is now evident that maternal smoking is associated with pre-term birth and low birth weight, low birth weight for gestational age, small head circumference, low Apgar score at 5 min, stillbirth and neonatal death.
