Abstract
BACKGROUND No published studies have evaluated in pregnant women with HIV weight gain with different antiretroviral drug classes. METHODS Data from a national cohort study were used. We compared absolute weight gain and occurrence of excessive weight gain in women with HIV who received during pregnancy integrase inhibitors (INSTI), protease inhibitors (PI), or non-nucleoside reverse transcriptase inhibitors (NNRTI). Excessive weight gain was defined according to the Institute of Medicine recommendations. Possible predictors of weight gain were assessed using univariate and multivariate analyses. RESULTS Among 273 cases (PI: 191, NNRTI: 43, INSTI: 39), the mean weight increase was 11.3 kg, and 25.4% of the mothers had an excessive weight increase. No significant differences were found among the three treatment groups for absolute weight increase, occurrence of excessive weight gain, infant birthweight, and other pregnancy and laboratory outcomes. The comparisons of individual drugs, although based on a limited number of cases, suggested no major differences. A significant positive correlation was found between weight gain and CD4+ T-cell increase during pregnancy. In multivariate analyses, drug class and nucleoside backbone were not associated with absolute or excessive weight increase. Excessive weight increase was significantly associated with week of delivery (adjusted odds ratio: 1.74, 95% CI 1.15, 2.63), obesity (5.21, 95% CI 1.85, 14.64), overweight (7.95, 95% CI 3.26, 19.39), recent substance use (5.96, 95% CI 1.13, 31.40) and fasting 2nd trimester hyperglycaemia (3.94, 95% CI 1.14, 13.65). CONCLUSIONS No significant differences in absolute weight change or occurrence of excessive weight gain were found among women with HIV who received during pregnancy different classes of antiretroviral drugs.

Nicotine Tob Res 2020; 21:835-840.

Abstract
INTRODUCTION The common genetic variant (rs1051730) in the 15q24 nicotinic acetylcholine receptor gene cluster CHRNA5-CHRNA3-CHRNB4 was associated with smoking quantity and has been reported to be associated also with reduced ability to quit smoking in pregnant women but results were inconsistent in nonpregnant women. The aim of this study was to explore the association between rs1051730 and smoking cessation during pregnancy in a sample of Dutch women. METHODS Data on smoking during pregnancy were available from 1337 women, who ever smoked, registered at the Netherlands Twin Register (NTR). Logistic regression was used to assess evidence for the association of rs1051730 genotype on smoking during pregnancy. In a subsample of 561 women, we investigated the influence of partner's smoking. Educational attainment and year of birth were used as covariates in both analyses. RESULTS There was evidence for a significant association between having one or more T alleles of the rs1051730 polymorphism and the likelihood of smoking during pregnancy (p = .03, odds ratio = 1.28, 95% CI = 1.02 to 1.61). However, this association attenuated when adjusting for birth cohort and educational attainment (p = .37, odds ratio = 1.12, 95% CI = 0.87 to 1.43). In the subsample, smoking spouse was highly associated with smoking during pregnancy, even when educational attainment and birth cohort were included in the model. CONCLUSIONS Our results did not support a strong association between this genetic variant and smoking during pregnancy. However, a strong association was observed with the smoking behavior of the partner, regardless of the genotype of the women. IMPLICATIONS The present study emphasizes the importance of social influences like spousal smoking on the smoking behavior of pregnant women. Further research is needed to address the role of rs1051730 genetic variant in influencing smoking cessation and the interaction with important environmental factors like the smoking behavior of the partner.

Abstract
Background: Many women continue to smoke during pregnancy, despite known risks, often in response to negative affect. Recent scholarship has begun to examine factors that decrease the success of behavioral treatments for smoking cessation in pregnancy, which are the preferred interventions. Alexithymia is one factor that may interfere with smoking cessation interventions. Alexithymia restricts access to emotional information and increases propensity toward maladaptive behaviors, including smoking. However, mechanisms underlying such effects are largely unknown. Objectives: Using data from a longitudinal treatment study, the present research examined difficulties with emotion regulation as a potential mechanism linking alexithymia and smoking. Pregnant smokers (n = 73; mean age = 24.78; SD = 4.50) completed measures related to alexithymia, smoking, emotion regulation, depression, anxiety, and anger at baseline and then again following eight sessions of Cognitive-Behavioral Smoking Cessation Treatment. Results: Nearly 40% of the sample met the criteria for alexithymia. The alexithymia group reported higher depression, anxiety, and anger. They also reported more difficulties with emotion regulation. In a path analysis, baseline alexithymia had a significant positive indirect effect on number of cigarettes smoked at the end of treatment through difficulties with emotion regulation. Conclusions/Importance: Similar to other studies, alexithymia limits the understanding of emotional information necessary for selection and implementation of adaptive coping responses. Our results extend the literature by suggesting that smoking may be an attempt to manage undifferentiated and unpleasant sensations created by alexithymia.

Abstract
OBJECTIVE To assess birth outcomes and cost-savings of an incentive-based prenatal smoking cessation program targeting low-income women in Colorado. DESIGN Prospective observational cohort with nonequivalent population control groups. SAMPLE Program participants (n = 2,231) linked to the birth certificate to ascertain birth outcomes compared to two reference populations from Pregnancy Risk Assessment Monitoring System (PRAMS) and Colorado live births based on the birth certificate. MEASUREMENTS Tobacco cessation metrics in the third trimester of pregnancy, neonatal low birth weight (<2,500 g), preterm birth (birth at <37 weeks gestation), neonatal intensive care unit (NICU) admission and maternal gestational hypertension. Cost-savings and return on investment (ROI) were projected using average Medicaid reimbursement. RESULTS Infants of mothers enrolled in the program had a lower risk of low birthweight (RR = 0.86; 95% CI = 0.75, 0.97), preterm birth (PTB) (RR = 0.76; 95% CI = 0.65, 0.88) and neonatal intensive care unit (NICU) admission (RR = 0.76; 95% CI = 0.66, 0.88) compared to the birth certificate population, corresponding to a ROI of $7.73 and an individual cost savings of $6,040. Compared to PRAMS, infants of enrolled mothers had a lower risk of PTB (RR = 0.72; 95% CI = 0.53, 0.99) and NICU admission (RR = 0.45; 95% CI = 0.32, 0.62), corresponding to an ROI of $2.79 and an individual cost savings of $2,182. CONCLUSIONS We found a reduction of adverse birth outcomes, and cost savings.

Abstract
OBJECTIVES The aim was to investigate the effect of -maternal smoking exposure assessed by urinary tobacco-specific nitrosamine metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-a1-butanol (NNAL) with adverse pregnancy outcomes. METHODS A total of 251 pregnant women were recruited. Urinary cotinine and NNAL were measured. Participants' sociodemographics were obtained by questionnaire and pregnancy outcomes were collected by charts review after delivery. RESULTS The prevalence of smoking was 8.4% (21 of 249), 1.2% (3 of 241), and 3.7% (9 of 241) in pregnant women according to questionnaire, cotinine, and NNAL, respectively. As compared with questionnaire positivity and cotinine levels, women with positive NNAL were independent determinants for spontaneous abortion (adjusted OR 12.357, 95% CI 2.053-74.368), preterm birth (adjusted OR 22.239, 95% CI 3.737-132.357), and small for gestational age (adjusted OR 6.915, 95% CI 1.385-34.524). CONCLUSIONS Urinary NNAL might be a useful biomarker in detection of maternal smoking status in association with adverse pregnancy outcomes. Use of this marker in preconception and pregnancy counselling before planning pregnancy may allow prevention of several adverse pregnancy outcomes.

Abstract
BACKGROUND Tobacco smoking remains one of the few preventable factors associated with complications in pregnancy, and has serious long-term implications for women and babies. Smoking in pregnancy is decreasing in high-income countries, but is strongly associated with poverty and is increasing in low- to middle-income countries. OBJECTIVES To assess the effects of smoking cessation interventions during pregnancy on smoking behaviour and perinatal health outcomes. SEARCH METHODS In this sixth update, we searched the Cochrane Pregnancy and Childbirth Group's Trials Register (13 November 2015), checked reference lists of retrieved studies and contacted trial authors. SELECTION CRITERIA Randomised controlled trials, cluster-randomised trials, and quasi-randomised controlled trials of psychosocial smoking cessation interventions during pregnancy. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and trial quality, and extracted data. Direct comparisons were conducted in RevMan, with meta-regression conducted in STATA 14. MAIN RESULTS The overall quality of evidence was moderate to high, with reductions in confidence due to imprecision and heterogeneity for some outcomes. One hundred and two trials with 120 intervention arms (studies) were included, with 88 trials (involving over 28,000 women) providing data on smoking abstinence in late pregnancy. Interventions were categorised as counselling, health education, feedback, incentives, social support, exercise and dissemination.In separate comparisons, there is high-quality evidence that counselling increased smoking cessation in late pregnancy compared with usual care (30 studies; average risk ratio (RR) 1.44, 95% confidence interval (CI) 1.19 to 1.73) and less intensive interventions (18 studies; average RR 1.25, 95% CI 1.07 to 1.47). There was uncertainty whether counselling increased the chance of smoking cessation when provided as one component of a broader maternal health intervention or comparing one type of counselling with another. In studies comparing counselling and usual care (largest comparison), it was unclear whether interventions prevented smoking relapse among women who had stopped smoking spontaneously in early pregnancy. However, a clear effect was seen in smoking abstinence at zero to five months postpartum (11 studies; average RR 1.59, 95% CI 1.26 to 2.01) and 12 to 17 months (two studies, average RR 2.20, 95% CI 1.23 to 3.96), with a borderline effect at six to 11 months (six studies; average RR 1.33, 95% CI 1.00 to 1.77). In other comparisons, the effect was unclear for most secondary outcomes, but sample sizes were small.Evidence suggests a borderline effect of health education compared with usual care (five studies; average RR 1.59, 95% CI 0.99 to 2.55), but the quality was downgraded to moderate as the effect was unclear when compared with less intensive interventions (four studies; average RR 1.20, 95% CI 0.85 to 1.70), alternative interventions (one study; RR 1.88, 95% CI 0.19 to 18.60), or when smoking cessation health education was provided as one component of a broader maternal health intervention.There was evidence feedback increased smoking cessation when compared with usual care and provided in conjunction with other strategies, such as counselling (average RR 4.39, 95% CI 1.89 to 10.21), but the confidence in the quality of evidence was downgraded to moderate as this was based on only two studies and the effect was uncertain when feedback was compared to less intensive interventions (three studies; average RR 1.29, 95% CI 0.75 to 2.20).High-quality evidence suggests incentive-based interventions are effective when compared with an alternative (non-contingent incentive) intervention (four studies; RR 2.36, 95% CI 1.36 to 4.09). However pooled effects were not calculable for comparisons with usual care or less intensive interventions (substantial heterogeneity, I2 = 93%).High-quality evidence suggests the effect is unclear in social support interventions provided by peers (six studies; average RR 1.42, 95% CI 0.98 to 2.07), in a single trial of support provided by partners, or when social support for smoking cessation was provided as part of a broader intervention to improve maternal health.The effect was unclear in single interventions of exercise compared to usual care (RR 1.20, 95% CI 0.72 to 2.01) and dissemination of counselling (RR 1.63, 95% CI 0.62 to 4.32).Importantly, high-quality evidence from pooled results demonstrated that women who received psychosocial interventions had a 17% reduction in infants born with low birthweight, a significantly higher mean birthweight (mean difference (MD) 55.60 g, 95% CI 29.82 to 81.38 g higher) and a 22% reduction in neonatal intensive care admissions. However the difference in preterm births and stillbirths was unclear. There did not appear to be adverse psychological effects from the interventions.The intensity of support women received in both the intervention and comparison groups has increased over time, with higher-intensity interventions more likely to have higher-intensity comparisons, potentially explaining why no clear differences were seen with increasing intervention intensity in meta-regression analyses. Among meta-regression analyses: studies classified as having 'unclear' implementation and unequal baseline characteristics were less effective than other studies. There was no clear difference between trials implemented by researchers (efficacy studies), and those implemented by routine pregnancy staff (effectiveness studies), however there was uncertainty in the effectiveness of counselling in four dissemination trials where the focus on the intervention was at an organisational level. The pooled effects were similar in interventions provided for women classified as having predominantly low socio-economic status, compared to other women. The effect was significant in interventions among women from ethnic minority groups; however not among indigenous women. There were similar effect sizes in trials with biochemically validated smoking abstinence and those with self-reported abstinence. It was unclear whether incorporating use of self-help manuals or telephone support increased the effectiveness of interventions. AUTHORS' CONCLUSIONS Psychosocial interventions to support women to stop smoking in pregnancy can increase the proportion of women who stop smoking in late pregnancy and the proportion of infants born low birthweight. Counselling, feedback and incentives appear to be effective, however the characteristics and context of the interventions should be carefully considered. The effect of health education and social support is less clear. New trials have been published during the preparation of this review and will be included in the next update.

Abstract
OBJECTIVE The aim of this study was to derive reference charts between the 15th and 20th week of gestation for biparietal diameter (BPD), occipito-frontal diameter (OFD), head circumference (HC), abdominal circumference (AC) and femur length (FL) compared to commonly used curves and to evaluate the impact of maternal body mass index (BMI), ultrasound equipment, fetal gender and nicotine abuse. METHODS In a cross-sectional study of 4,265 low-risk pregnancies, biometric data were obtained between the 15th and 20th week of gestation. The statistical analysis included descriptive data, fitting regression curves for the 5th, 50th and 95th quantile as well as multivariate quantile regression analyses. RESULTS Reference curves for BPD, OFD, HC, AC and FL showed a linear increase between the 15th and 20th week of gestation. New equations and reference charts are presented in this study. In a comparison of influence factors sex, BMI and ultrasound systems have an impact. CONCLUSION As a result of the study, we determined current growth curves for BPD, OFD, HC, AC and FL for both sexes as well as for males and females separately. The updated growth curves for all biometric parameters differ from the curves used commonly in the last two decades.

Abstract
AIMS To examine the ability of different common measures of cigarette dependence to predict smoking cessation during pregnancy. DESIGN Secondary analysis of data from a parallel-group randomized controlled trial of physical activity for smoking cessation. The outcomes were biochemically validated smoking abstinence at 4 weeks post-quit and end-of-pregnancy. SETTING Women identified as smokers in antenatal clinics in 13 hospital trusts predominantly in southern England, who were recruited to a smoking cessation trial. PARTICIPANTS Of 789 pregnant smokers recruited, 784 were included in the analysis. MEASUREMENTS Using random-effect logistic regression models, we analysed the effects of baseline measures of cigarette dependence, including numbers of cigarettes smoked daily, Fagerström Test of Cigarette Dependence (FTCD) score, the two FTCD subscales of Heaviness of Smoking Index (HSI) and non-Heaviness of Smoking Index (non-HSI), expired carbon monoxide (CO) level and urges to smoke (strength and frequency) on smoking cessation. Associations were adjusted for significant socio-demographic/health behaviour predictors and trial variables, and area under the receiver operating characteristic (ROC) curve was used to determine the predictive ability of the model for each measure of dependence. FINDINGS All the dependence variables predicted abstinence at 4 weeks and end-of-pregnancy. At 4 weeks, the adjusted odds ratio (OR) (95% confidence interval) for a unit standard deviation increase in FTCD was 0.59 (0.47-0.74), expired CO = 0.54 (0.41-0.71), number of cigarettes smoked per day 0.65 (0.51-0.84) and frequency of urges to smoke 0.79 (0.63-0.98); at end-of-pregnancy they were: 0.60 (0.45-0.81), 0.55 (0.37-0.80), 0.70 (0.49-0.98) and 0.69 (0.51-0.94), respectively. HSI and non-HSI exhibited similar results to the full FTCD. CONCLUSIONS Four common measures of dependence, including number of cigarettes smoked per day, scores for Fagerström Test of Cigarette Dependence and frequency of urges and level of expired CO, all predicted smoking abstinence in the short term during pregnancy and at end-of-pregnancy with very similar predictive validity.

Abstract
OBJECTIVE To evaluate a web-based contingency management program (CM) and a phone-delivered cessation counseling program (Smoking Cessation for Healthy Births [SCHB]) with pregnant smokers in rural Appalachia who were ≤12 weeks gestation at enrollment. DESIGN Two group randomized design. SETTING Home-based cessation programs in rural Appalachia Ohio and Kentucky. PARTICIPANTS A community sample of pregnant smokers (N = 17). METHODS Participants completed demographic and smoking-related questionnaires and were assigned to CM (n = 7) or SCHB (n = 10) conditions. Smoking status was assessed monthly using breath carbon monoxide and urinary cotinine. RESULTS For CM, two of seven (28.57%) of the participants achieved abstinence, and three of 10 (30%) of those enrolled in SCHB were abstinent by late in pregnancy. Participants in CM attained abstinence more rapidly than those in SCHB. However, those in SCHB experienced less relapse to smoking, and a greater percentage of these participants reduced their smoking by at least 50%. CONCLUSION Based on this initial evaluation, the web-based CM and SCHB programs appeared to be feasible for use with rural pregnant smokers with acceptable program adherence for both approaches. Future researchers could explore combining these programs to capitalize on the strengths of each, for example, rapid smoking cessation based on CM incentives and better sustained cessation or reductions in smoking facilitated by the counseling support of SCHB.

Abstract
BACKGROUND AND OBJECTIVE Tobacco during pregnancy affects the health of the newborn. The aim was to assess the effect of maternal exposure to active and passive tobacco and of smoking cessation on the risk of preterm deliveries and birth weight, taking into account other risk factors. PATIENTS AND METHOD Longitudinal study conducted in 282 healthy pregnant women. General, obstetrical and hematological data were collected as it was the smoking habit during pregnancy. Pregnant women were classified as "exposed to smoke" (active smoker and passive smoker) and "unexposed to smoke" (non-smokers and women who quitted smoking during pregnancy). RESULTS A percentage of 59.2 were non-smokers, 18.4% active smokers, 8.5% second-hand smokers and 13.8% had stopped smoking. Unexposed pregnant women who stopped smoking had the same risk of premature deliveries and children with similar birth weight as non-smoker women. Active and second-hand smokers were at higher risk of preterm deliveries than non-smokers (odds ratio [OR] 6.5, 95% confidence interval [95% CI] 1.4-30.8 and OR 6.2, 95% CI 1.0-38.9, respectively); however, higher levels of hemoglobin in the 1st and 3rd trimester exerted a protective effect (OR 0.9, 95% CI 0.8-0.9). Active and second-hand smokers had babies weighing less than non-smokers (around 129 and 178g less, respectively). CONCLUSIONS Active or passive exposure to smoke during pregnancy and lower hemoglobin levels are associated with an increased risk of premature deliveries and lower birth weight. Stopping smoking during pregnancy prevents these detrimental effects.
