“…Tong et al. reported that 10% of woman who claimed to have stopped smoking showed biochemical evidence of continued smoking 24 . It is possible that we overestimated the risk of RWG in the ex-smoker group, and that smoking cessation during pregnancy may have a greater effect on RWG in early infancy than the study results indicate.…”

BackgroundAlthough several studies have focused on the association between maternal smoking during pregnancy and rapid weight gain (RWG) during infancy, the dose-response relationship has not yet been confirmed, and very few studies have included Asian populations. Using a record-linkage method, we examined the association between maternal smoking during pregnancy and RWG in infants at around 4 months of age to clarify the dose-response relationship.MethodsTwo databases were used: maternal check-ups during pregnancy and early infancy check-ups (between April 1, 2013 and March 31, 2014 in Okinawa, Japan) were linked via IDs and provided to us after unlinkable anonymizing. For 10,433 subjects (5229 boys and 5204 girls), we calculated the change in infants' weight z-score by subtracting the z-score of their birth weight from their weight at early infancy check-ups. Smoking exposure was categorized into five groups. We used Poisson regression to examine the association of maternal smoking during pregnancy with RWG in early infancy.ResultsOverall, 1524 (14.6%) were ex-smoker and 511 (4.9%) were current smoker. Compared with the reference category of non-smokers, the adjusted risk ratio of RWG was 1.18 (95% confidence interval [CI], 1.06–1.32) for ex-smokers, 1.18 (95% CI, 0.93–1.50) for those who smoked 1–5 cigarettes per day, 1.57 (95% CI, 1.24–2.00) for those who smoked 6–10 cigarettes per day, and 2.13 (95% CI, 1.51–3.01) for those who smoked ≥11 cigarettes per day. There was a clear dose-response relationship.ConclusionOur study suggests that maternal smoking during pregnancy is associated in a dose-dependent manner with increased risk of RWG in early infancy.

Introduction The 5A’s (Ask, Advise, Assess, Assist, and Arrange) strategy, a best-practice approach for cessation counseling, has been widely implemented in high-income countries for pregnant women; however, no studies have evaluated implementation in middle-income countries. The study objectives were to assess smoking patterns and receipt of 5A’s among pregnant women in Buenos Aires, Argentina and Montevideo, Uruguay. Methods Data were collected through administered questionnaires to women at delivery hospitalizations during October 2011–May 2012. Eligible women attended one of 12 maternity hospitals or 21 associated prenatal care clinics. The questionnaire included demographic data, tobacco use/cessation behaviors, and receipt of the 5A’s. Self-reported cessation was verified with saliva cotinine. Results Overall, of 3400 pregnant women, 32.8% smoked at the beginning of pregnancy; 11.9% quit upon learning they were pregnant or later during pregnancy, and 20.9% smoked throughout pregnancy. Smoking prevalence varied by country with 16.1% and 26.7% who smoked throughout pregnancy in Argentina and Uruguay, respectively. Among pregnant smokers in Argentina, 23.8% reported that a provider asked them about smoking at more than one prenatal care visit; 18.5% were advised to quit; 5.3% were assessed for readiness to quit, 4.7% were provided assistance, and 0.7% reported follow-up was arranged. In Uruguay, those percentages were 36.3%, 27.9%, 5.4%, 5.6%, and 0.2%, respectively. Conclusions Approximately, one in six pregnant women smoked throughout pregnancy in Buenos Aires and one in four in Montevideo. However, a low percentage of smokers received any cessation assistance in both countries. Healthcare providers are not fully implementing the recommended 5A’s intervention to help pregnant women quit smoking.

Background In many countries, smoking is considered as the most important preventable risk factor for a complicated pregnancy and delivery. However in Denmark, there is no clear picture of pregnant women. The aim was therefore to examine the prevalence, characteristics and registration of maternal smoking and quitting during pregnancy as well as estimate the potential for improvement. Methods This is a cohort study on smoking and quitting prevalence among 422,221 pregnant women in Denmark from 2006-2012. Data from the Danish National Birth Register was linked with data from the Danish National Smoking Cessation Database in order to identify pregnant smokers undertaking a formalised smoking cessation intervention. Results Overall, 13% of the pregnant women were smokers. The smoking prevalence was highest among mothers younger than 25 years of age (29%) compared to 10-11% among the other age groups. All prognostic factors in the final analyses were in some way associated with the outcome. A group of 1,279 pregnant women underwent formal smoking cessation intervention programs with follow-up after 6 months. Of these, 232 were registered as non-smokers and 40 had no information on smoking in the Danish National Birth Registry. The potential for reducing smoking among pregnant women was high. 25-32% more quitters would be expected with a comprehensive Gold Standard Programme for smoking cessation. Conclusion This study indicates an urgent need for increased focus on offering effective smoking cessation programs to all groups of pregnant smokers, but with a special attention to the youngest group.
