Abstract
BACKGROUND Single mothers in South Korea are vulnerable to developing smoking habits, due to many difficulties and limitations; however, they have often been overlooked by smoking cessation support services. Therefore, this study aimed to investigate the general and smoking-related characteristics of single mothers registered with the Visiting a Smoking Cessation Service in Seoul, South Korea, to identify factors associated with smoking cessation maintenance at 4 weeks and 24 weeks after they initially quit smoking. METHODS The participants were 77 single mothers registered in the Smoking Cessation Service Program. Data were included from a three-year span (January 2017-December 2019). Smoking cessation counseling, motivational enhancement, and self-exploration counseling were provided for six months. The participants were evaluated on their smoking cessation status at 4 weeks and 24 weeks. RESULTS Most participants were aged 22 years or younger. The rates of smoking cessation maintenance were 58.4 and 18% at 4 weeks and 24 weeks, respectively. The higher the number of counseling sessions, the higher the participants' chances of maintaining smoking in all non-smoking periods, and whether pregnancy, CO level, and drinking were significant only in a short-term non-smoking period (4 weeks). CONCLUSIONS Our results suggest that the number of smoking cessation counseling sessions is important for long-term smoking cessation beyond short-term cessation in single mothers. To increase the smoking cessation rate of single mothers, it is important to conduct customized smoking cessation counseling at the time of smoking cessation and continue such counseling in the long term.

Abstract
BACKGROUND Tobacco smoking in pregnancy causes serious health problems for the developing fetus and mother. When used by non-pregnant smokers, pharmacotherapies (nicotine replacement therapy (NRT), bupropion, and varenicline) are effective for increasing smoking cessation, however their efficacy and safety in pregnancy remains unknown. Electronic cigarettes (ECs) are becoming widely used, but their efficacy and safety when used for smoking cessation in pregnancy are also unknown. OBJECTIVES To determine the efficacy and safety of smoking cessation pharmacotherapies and ECs used during pregnancy for smoking cessation in later pregnancy and after childbirth, and to determine adherence to smoking cessation pharmacotherapies and ECs for smoking cessation during pregnancy. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 May 2019), trial registers, and grey literature, and checked references of retrieved studies. SELECTION CRITERIA Randomised controlled trials (RCTs) conducted in pregnant women, comparing smoking cessation pharmacotherapy or EC use with either placebo or no pharmacotherapy/EC control. We excluded quasi-randomised, cross-over, and within-participant designs, and RCTs with additional intervention components not matched between trial arms. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methods. The primary efficacy outcome was smoking cessation in later pregnancy; safety was assessed by 11 outcomes (principally birth outcomes) that indicated neonatal and infant well-being. We also collated data on adherence to trial treatments. We calculated the risk ratio (RR) or mean difference (MD) and the 95% confidence intervals (CI) for each outcome for each study, where possible. We grouped eligible studies according to the type of comparison. We carried out meta-analyses where appropriate. MAIN RESULTS We included 11 trials that enrolled a total of 2412 pregnant women who smoked at enrolment, nine trials of NRT and two trials of bupropion as adjuncts to behavioural support, with comparable behavioural support provided in the control arms. No trials investigated varenicline or ECs. We assessed four trials as at low risk of bias overall. The overall certainty of the evidence was low across outcomes and comparisons as assessed using GRADE, with reductions in confidence due to risk of bias, imprecision, and inconsistency. Compared to placebo and non-placebo (behavioural support only) controls, there was low-certainty evidence that NRT increased the likelihood of smoking abstinence in later pregnancy (RR 1.37, 95% CI 1.08 to 1.74; I² = 34%, 9 studies, 2336 women). However, in subgroup analysis by comparator type, there was a subgroup difference between placebo-controlled and non-placebo controlled RCTs (test for subgroup differences P = 0.008). There was unclear evidence of an effect in placebo-controlled RCTs (RR 1.21, 95% CI 0.95 to 1.55; I² = 0%, 6 studies, 2063 women), whereas non-placebo-controlled trials showed clearer evidence of a benefit (RR 8.55, 95% CI 2.05 to 35.71; I² = 0%, 3 studies, 273 women). An additional subgroup analysis in which studies were grouped by the type of NRT used found no difference in the effectiveness of NRT in those using patches or fast-acting NRT (test for subgroup differences P = 0.08). There was no evidence of a difference between NRT and control groups in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care, caesarean section, congenital abnormalities, or neonatal death. In one study infants born to women who had been randomised to NRT had higher rates of 'survival without developmental impairment' at two years of age compared to the placebo group. Non-serious adverse effects observed with NRT included headache, nausea, and local reactions (e.g. skin irritation from patches or foul taste from gum), but data could not be pooled. Adherence to NRT treatment regimens was generally low. We identified low-certainty evidence that there was no difference in smoking abstinence rates observed in later pregnancy in women using bupropion when compared to placebo control (RR 0.74, 95% CI 0.21 to 2.64; I² = 0%, 2 studies, 76 women). Evidence investigating the safety outcomes of bupropion use was sparse, but the existing evidence showed no difference between the bupropion and control group. AUTHORS' CONCLUSIONS NRT used for smoking cessation in pregnancy may increase smoking cessation rates in late pregnancy. However, this evidence is of low certainty, as the effect was not evident when potentially biased, non-placebo-controlled RCTs were excluded from the analysis. Future studies may therefore change this conclusion. We found no evidence that NRT has either positive or negative impacts on birth outcomes; however, the evidence for some of these outcomes was also judged to be of low certainty due to imprecision and inconsistency. We found no evidence that bupropion may be an effective aid for smoking cessation during pregnancy, and there was little evidence evaluating its safety in this population. Further research evidence on the efficacy and safety of pharmacotherapy and EC use for smoking cessation in pregnancy is needed, ideally from placebo-controlled RCTs that achieve higher adherence rates and that monitor infants' outcomes into childhood. Future RCTs of NRT should investigate higher doses than those tested in the studies included in this review.

Understanding the experiences, perspectives and values of indigenous women around smoking cessation in pregnancy: systematic review and thematic synthesis of qualitative studies. Int J Equity Health 2019; 18:74. [PMID: 31118025 PMCID: PMC6532160 DOI: 10.1186/s12939-019-0981-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2019] [Accepted: 05/10/2019] [Indexed: 12/25/2022] Open
Abstract
Background The prevalence of smoking during pregnancy among indigenous women approaches 50% and is associated with sudden infant death, pregnancy loss, preterm delivery, low birth weight, and anatomical deformity. This study aims to synthesise qualitative studies by reporting experiences, perceptions, and values of smoking cessation among pregnant indigenous women to inform potential interventions. Method A highly-sensitive search of MEDLINE, Embase, PsychINFO, and CINAHL, in conjunction with analysis of Google Scholar and reference lists of related studies was conducted in March 2018. We utilised two methods (thematic synthesis and an indigenous Māori analytical framework) in parallel to analyse data. Completeness of reporting in studies was evaluated using the Consolidated Criteria for Reporting Qualitative Studies (COREQ) framework. Results We included seven studies from Australia and New Zealand involving 250 indigenous women. Three themes were identified. Realising well-being and creating agency included giving the best start to baby, pride in being a healthy mum, female role models, and family support. Understanding the drivers for smoking included the impact of stress and chaos that hindered prioritisation of self-care, the social acceptability of smoking, guilt and feeling judged, and inadequate information about the risks of smoking. Indigenous women strongly preferred culturally responsive approaches to smoking cessation, placing value on programs designed specifically for and by indigenous people, that were accessible, and provided an alternative to smoking. Conclusion Future interventions and smoking cessation programmes might be more effective and acceptable to indigenous women and families when they harness self-agency and the desire for a healthy baby, recognise the high value of indigenous peer involvement, and embed a social focus in place of smoking as a way to maintain community support and relationships. Development and evaluation of smoking cessation programs for pregnant indigenous women and families is warranted.

Abstract
The importance of breastfeeding is clear. However, global action to support breastfeeding is hindered by the lack of reliable standard data, which continues to impede progress. Routinely collected data can monitor the effectiveness of health policy, evaluate interventions, and enhance international research collaboration and comparisons. Use of routine data to support effective public health initiatives such as smoking cessation has been demonstrated. However, the data collected about infant feeding practices worldwide is inconsistent in timing, methods, definitions, detail, storage, and consistency. Improvements to the reach and quality of routinely collected data about infant feeding are needed to strengthen the global evidence and policy base. An international collaborative effort is called for to progress this.

Abstract
Despite significant population level declines, smoking during pregnancy remains a major public health issue in the United States (US). Approximately 360,000-500,000 smoke-exposed infants are born yearly, and prenatal smoking remains a leading modifiable cause of poor birth outcomes (e.g. birth < 37 gestational weeks, low birth weight, perinatal mortality). Women who smoke during pregnancy are more likely to be younger and from disadvantaged socioeconomic and racial and ethnic groups, with some US geographic regions reporting increased prenatal smoking rates since 2000. Such disparities in maternal prenatal smoking suggests some pregnant women face unique barriers to cessation. This paper reviews the current state and future direction of smoking cessation in pregnancy in the US. We briefly discuss the etiology of smoking addiction among women, the pathophysiology and effects of tobacco smoke exposure on pregnant women and their offspring, and the emerging issue of electronic nicotine delivery systems. Current population-based and individual smoking cessation interventions are reviewed in the context of pregnancy and barriers to cessation among US women. Finally, we consider interventions that are on the horizon and areas in need of further investigation.

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
Objectives Process evaluation data are essential to document the fidelity of program implementation by clinical staff and confirm patient behavior change. This report presents a process evaluation model applied to the Smoking Cessation and Reduction in Pregnancy Treatment Dissemination Initiative for the statewide, home-based West Virginia Right From The Start Project. Methods Trained RFTS Designated Care Coordinators, nurses and social workers, of 50+ primary care agencies in all 55 counties, delivered SCRIPT to Medicaid patients who smoked. Results The process evaluation defined the level of DCC delivery of seven core SCRIPT procedures to produce a Program Implementation Index: a summary performance metric. A SCRIPT PII > 0.80 was established as the RFTS adoption standard. The PII increased from 0.53 in 2004 to 0.65 in 2006-2007 to 0.77 in 2009-2010. Although the PII > 0.80 was not achieved, exposure rates were increased for all seven SCRIPT procedures. Agency and DCC turnover, a transient patient population, and recession of 2008-2010 were barriers to achieving the adoption metric and implementation of an experimental design. A quasi-experimental Stratified, Matched Comparison (C) Group Design was selected to evaluate behavioral impact differences between a RFTS-Comparison (C) Group from 2006 to 2007 and the RFTS-SCRIPT E Group from 2009 to 2010. Impact analyses of the DCC delivery of the SCRIPT Program with higher fidelity documented a statistically significant increase in the cessation rate from 4.6 % and significant reduction rate from 6.9 % for the (C) Group in 2006-2007 to 13.9 % and 11.22 % respectively for the E Group in 2009-2010. Conclusion The PEM can assist statewide, home-based prenatal care programs to improve the quality of delivery and evaluate counseling programs.

Abstract
PURPOSE Interconception care (ICC) is recommended to improve birth outcomes by targeting maternal risk factors, but little is known about its implementation. We evaluated the frequency and nature of ICC delivered to mothers at well-child visits and maternal receptivity to these practices. METHODS We surveyed a convenience sample of mothers accompanying their child to well-child visits at family medicine academic practices in the IMPLICIT (Interventions to Minimize Preterm and Low Birth Weight Infants Through Continuous Improvement Techniques) Network. Health history, behaviors, and the frequency of the child's physician addressing maternal depression, tobacco use, family planning, and folic acid supplementation were assessed, along with maternal receptivity to advice. RESULTS Three-quarters of the 658 respondents shared a medical home with their child. Overall, 17% of respondents reported a previous preterm birth, 19% reported a history of depression, 25% were smoking, 26% were not using contraception, and 58% were not taking folic acid. Regarding advice, 80% of mothers who smoked were counseled to quit, 59% reported depression screening, 71% discussed contraception, and 44% discussed folic acid. Screening for depression and family planning was more likely when the mother and child shared a medical home (P <.05). Most mothers, nearly 95%, were willing to accept health advice from their child's physician regardless of whether a medical home was shared (P >.05). CONCLUSIONS Family physicians provide key elements of ICC at well-child visits, and mothers are highly receptive to advice from their child's physician even if they receive primary care elsewhere. Routine integration of ICC at these visits may provide an opportunity to reduce maternal risk factors for adverse subsequent birth outcomes.

Abstract
BACKGROUND Smoking in pregnancy is a public health problem. When used by non-pregnant smokers, pharmacotherapies (nicotine replacement therapy (NRT), bupropion and varenicline) are effective for smoking cessation, however, their efficacy and safety in pregnancy remains unknown. Electronic Nicotine Delivery Systems (ENDS), or e-cigarettes, are becoming widely used but their efficacy and safety when used for smoking cessation in pregnancy are also unknown. OBJECTIVES To determine the efficacy and safety of smoking cessation pharmacotherapies (including NRT, varenicline and bupropion), other medications, or ENDS when used for smoking cessation in pregnancy. SEARCH METHODS We searched the Pregnancy and Childbirth Group's Trials Register (11 July 2015), checked references of retrieved studies, and contacted authors. SELECTION CRITERIA Randomised controlled trials (RCTs) conducted in pregnant women with designs that permit the independent effects of any type of pharmacotherapy or ENDS on smoking cessation to be ascertained were eligible for inclusion.The following RCT designs are included.Placebo-RCTs: any form of NRT, other pharmacotherapy, or ENDS, with or without behavioural support/cognitive behaviour therapy (CBT), or brief advice, compared with an identical placebo and behavioural support of similar intensity.RCTs providing a comparison between i) any form of NRT, other pharmacotherapy, or ENDS added to behavioural support/CBT, or brief advice and ii) behavioural support of similar (ideally identical) intensity.Parallel- or cluster-randomised trials were eligible for inclusion. Quasi-randomised, cross-over and within-participant designs were not, due to the potential biases associated with these designs. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias and also independently extracted data and cross checked individual outcomes of this process to ensure accuracy. The primary efficacy outcome was smoking cessation in later pregnancy (in all but one trial, at or around delivery); safety was assessed by 11 outcomes (principally birth outcomes) that indicated neonatal and infant well-being; and we also collated data on adherence with trial treatments. MAIN RESULTS This review includes a total of nine trials which enrolled 2210 pregnant smokers: eight trials of NRT and one trial of bupropion as adjuncts to behavioural support/CBT. The risk of bias was generally low across trials with virtually all domains of the 'Risk of bias' assessment tool being satisfied for the majority of studies. We found no trials investigating varenicline or ENDS. Compared to placebo and non-placebo controls, there was a difference in smoking rates observed in later pregnancy favouring use of NRT (risk ratio (RR) 1.41, 95% confidence interval (CI) 1.03 to 1.93, eight studies, 2199 women). However, subgroup analysis of placebo-RCTs provided a lower RR in favour of NRT (RR 1.28, 95% CI 0.99 to 1.66, five studies, 1926 women), whereas within the two non-placebo RCTs there was a strong positive effect of NRT, (RR 8.51, 95% CI 2.05 to 35.28, three studies, 273 women; P value for random-effects subgroup interaction test = 0.01). There were no differences between NRT and control groups in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care, caesarean section, congenital abnormalities or neonatal death. Compared to placebo group infants, at two years of age, infants born to women who had been randomised to NRT had higher rates of 'survival without developmental impairment' (one trial). Generally, adherence with trial NRT regimens was low. Non-serious side effects observed with NRT included headache, nausea and local reactions (e.g. skin irritation from patches or foul taste from gum), but these data could not be pooled. AUTHORS' CONCLUSIONS NRT used in pregnancy for smoking cessation increases smoking cessation rates measured in late pregnancy by approximately 40%. There is evidence, suggesting that when potentially-biased, non-placebo RCTs are excluded from analyses, NRT is no more effective than placebo. There is no evidence that NRT used for smoking cessation in pregnancy has either positive or negative impacts on birth outcomes. However, evidence from the only trial to have followed up infants after birth, suggests use of NRT promotes healthy developmental outcomes in infants. Further research evidence on NRT efficacy and safety is needed, ideally from placebo-controlled RCTs which achieve higher adherence rates and which monitor infants' outcomes into childhood. Accruing data suggests that it would be ethical for future RCTs to investigate higher doses of NRT than those tested in the included studies.

Lok KYW, Bai DL, Tarrant M. Predictors of breastfeeding initiation in Hong Kong and Mainland China born mothers. BMC Pregnancy Childbirth 2015; 15:286. [PMID: 26531299 PMCID: PMC4632339 DOI: 10.1186/s12884-015-0719-5] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2015] [Accepted: 10/23/2015] [Indexed: 05/31/2024] Open
Abstract
BACKGROUND In recent years there has been a steady influx of immigrants into Hong Kong from Mainland China, where breastfeeding patterns differ. Studies in other regions have found substantial differences in breastfeeding rates between native-born and immigrant mothers. The purpose of this study was to examine factors associated with breastfeeding initiation in Hong Kong born and Mainland China born mothers living in Hong Kong. METHODS We used a multi-center cross-sectional study design and recruited 2761 new mothers from the postnatal wards of all eight public hospitals in Hong Kong that offer obstetric services. We assessed breastfeeding status as well as various socio-demographic, maternal and birth characteristics. Chi-square tests and multivariable logistic regression were used to identify the predictors of breastfeeding initiation in Hong Kong born and Mainland China born participants. RESULTS 80.3 % of Hong Kong and 81.1 % of Mainland Chinese born women initiated breastfeeding. In the fully adjusted models, multiparity (Odds Ratio [OR] 0.53, 95 % CI 0.43-0.66) and maternal smoking (OR 0.29, 95 % CI 0.18-0.45) were strongly associated with failure to initiate breastfeeding in both Hong Kong and Mainland China born participants. In Hong Kong born mothers, participants with lower maternal education and those who had a cesarean section were significantly less likely to breastfeed. For Mainland China born mothers, paternal smoking (OR 0.70, 95 % CI 0.49-0.99) and having a pregnancy-related health problem (OR 0.60, 95 % CI 0.38-0.94) were both additional risk factors for not breastfeeding. CONCLUSION This study has identified predictors of breastfeeding initiation in Hong Kong and Mainland China born mothers. Given the current high breastfeeding initiation rates among both groups, antenatal breastfeeding education and promotion programmes need to specifically intervene with sub-groups of pregnant women at risk for not breastfeeding so that their efforts are more strategic and cost-effective.

Abstract
OBJECTIVE To determine predictive risk factors for Apgar scores < 7 at 5 minutes at two hospitals providing tertiary care and secondary care, respectively. METHODS A retrospective registry cohort study of 21126 births (2006-2010) using data from digital medical records. Risk factors were analyzed by logistic regression analyses. RESULTS AS(5 min) < 7 was multivariately associated with the following: preterm birth; gestational week 32 + 0-36 + 6, OR = 3.9 (95% CI 2.9-5.3); week 28 + 0-31 + 6, OR = 8 (5-12); week < 28 + 0, OR = 15 (8-29); postterm birth, OR = 2.0 (1.7-2.3); multiple pregnancy, OR = 3.53 (1.79-6.96); previous cesarean section, OR = 3.67 (2.31-5.81); BMI 25-29, OR = 1.30 (1.09-1.55); BMI ≥ 30 OR = 1.70 (1.20-2.41); nonnormal CTG at admission, OR = 1.98 (1.48-2.66). ≥ 1-para was associated with a decreased risk for AS(5 min) < 7, OR = 0.34 (0.25-0.47). In the univariate logistic regression analysis AS(5 min) < 7 was associated with tertiary level care, OR = 1.48 (1.17-1.87); however, in the multivariate analysis there was no significant difference. CONCLUSION A number of partially preventable risk factors were identified, preterm birth being the most evident. Further, no significant difference between the two hospital levels regarding the risk for low Apgar scores was detected.

Abstract
BACKGROUND Tobacco smoking in pregnancy remains one of the few preventable factors associated with complications in pregnancy, stillbirth, low birthweight and preterm birth 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 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 fifth update, we searched the Cochrane Pregnancy and Childbirth Group's Trials Register (1 March 2013), checked reference lists of retrieved studies and contacted trial authors to locate additional unpublished data. SELECTION CRITERIA Randomised controlled trials, cluster-randomised trials, randomised cross-over trials, and quasi-randomised controlled trials (with allocation by maternal birth date or hospital record number) 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, and subgroup analyses and sensitivity analysis were conducted in SPSS. MAIN RESULTS Eighty-six trials were included in this updated review, with 77 trials (involving over 29,000 women) providing data on smoking abstinence in late pregnancy.In separate comparisons, counselling interventions demonstrated a significant effect compared with usual care (27 studies; average risk ratio (RR) 1.44, 95% confidence interval (CI) 1.19 to 1.75), and a borderline effect compared with less intensive interventions (16 studies; average RR 1.35, 95% CI 1.00 to 1.82). However, a significant effect was only seen in subsets where counselling was provided in conjunction with other strategies. It was unclear whether any type of counselling strategy is more effective than others (one study; RR 1.15, 95% CI 0.86 to 1.53). In studies comparing counselling and usual care (the largest comparison), it was unclear whether interventions prevented smoking relapse among women who had stopped smoking spontaneously in early pregnancy (eight studies; average RR 1.06, 95% CI 0.93 to 1.21). However, a clear effect was seen in smoking abstinence at zero to five months postpartum (10 studies; average RR 1.76, 95% CI 1.05 to 2.95), a borderline effect at six to 11 months (six studies; average RR 1.33, 95% CI 1.00 to 1.77), and a significant effect at 12 to 17 months (two studies, average RR 2.20, 95% CI 1.23 to 3.96), but not in the longer term. In other comparisons, the effect was not significantly different from the null effect for most secondary outcomes, but sample sizes were small.Incentive-based interventions had the largest effect size compared with a less intensive intervention (one study; RR 3.64, 95% CI 1.84 to 7.23) and an alternative intervention (one study; RR 4.05, 95% CI 1.48 to 11.11).Feedback interventions demonstrated a significant effect only when compared with usual care and provided in conjunction with other strategies, such as counselling (two studies; average RR 4.39, 95% CI 1.89 to 10.21), but the effect was unclear when compared with a less intensive intervention (two studies; average RR 1.19, 95% CI 0.45 to 3.12).The effect of health education was unclear when compared with usual care (three studies; average RR 1.51, 95% CI 0.64 to 3.59) or less intensive interventions (two studies; average RR 1.50, 95% CI 0.97 to 2.31).Social support interventions appeared effective when provided by peers (five studies; average RR 1.49, 95% CI 1.01 to 2.19), but the effect was unclear in a single trial of support provided by partners.The effects were mixed where the smoking interventions were provided as part of broader interventions to improve maternal health, rather than targeted smoking cessation interventions.Subgroup analyses on primary outcome for all studies showed the intensity of interventions and comparisons has increased over time, with higher intensity interventions more likely to have higher intensity comparisons. While there was no significant difference, trials where the comparison group received usual care had the largest pooled effect size (37 studies; average RR 1.34, 95% CI 1.25 to 1.44), with lower effect sizes when the comparison group received less intensive interventions (30 studies; average RR 1.20, 95% CI 1.08 to 1.31), or alternative interventions (two studies; average RR 1.26, 95% CI 0.98 to 1.53). More recent studies included in this update had a lower effect size (20 studies; average RR 1.26, 95% CI 1.00 to 1.59), I(2)= 3%, compared to those in the previous version of the review (50 studies; average RR 1.50, 95% CI 1.30 to 1.73). There were similar effect sizes in trials with biochemically validated smoking abstinence (49 studies; average RR 1.43, 95% CI 1.22 to 1.67) and those with self-reported abstinence (20 studies; average RR 1.48, 95% CI 1.17 to 1.87). There was no significant difference between trials implemented by researchers (efficacy studies), and those implemented by routine pregnancy staff (effectiveness studies), however the effect was unclear in three dissemination trials of counselling interventions where the focus on the intervention was at an organisational level (average RR 0.96, 95% CI 0.37 to 2.50). The pooled effects were similar in interventions provided for women with predominantly low socio-economic status (44 studies; average RR 1.41, 95% CI 1.19 to 1.66), compared to other women (26 studies; average RR 1.47, 95% CI 1.21 to 1.79); though the effect was unclear in interventions among women from ethnic minority groups (five studies; average RR 1.08, 95% CI 0.83 to 1.40) and aboriginal women (two studies; average RR 0.40, 95% CI 0.06 to 2.67). Importantly, pooled results demonstrated that women who received psychosocial interventions had an 18% reduction in preterm births (14 studies; average RR 0.82, 95% CI 0.70 to 0.96), and infants born with low birthweight (14 studies; average RR 0.82, 95% CI 0.71 to 0.94). There did not appear to be any adverse effects from the psychosocial interventions, and three studies measured an improvement in women's psychological wellbeing. 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 reduce low birthweight and preterm births.

Effectiveness of the gold standard programmes (GSP) for smoking cessation in pregnant and non-pregnant women. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2013; 10:3653-66. [PMID: 23959083 PMCID: PMC3774462 DOI: 10.3390/ijerph10083653] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2013] [Revised: 08/02/2013] [Accepted: 08/12/2013] [Indexed: 12/25/2022]
Abstract
Background: Smoking is considered the most important preventable risk factor in relation to the development of complications during pregnancy and delivery. The aim of this study was to evaluate the effectiveness of an intensive 6-week gold standard programme (GSP) on pregnant women in real life. Methods: This was a prospective cohort study based on data from a national Danish registry on smoking cessation interventions. The study population included 10,682 women of a fertile age. The pregnancy status of the study population was identified using the National Patient Registry. Results: The response rate to follow up was 76%. The continuous abstinence rate for both pregnant and non-pregnant smokers was 24–32%. The following prognostic factors for continuous abstinence were identified: programme format (individual/group), older age, heavy smoking, compliance with the programme, health professional recommendation, and being a disadvantaged smoker. Conclusions: The GSP seems to be as effective among pregnant smokers as among non-pregnant smoking women. Due to the relatively high effect and clinical significance, the GSP would be an attractive element in smoking cessation intervention among pregnant women.

Abstract
BACKGROUND Smoking in pregnancy is a substantial public health problem. When used by non-pregnant smokers, pharmacotherapies [nicotine replacement therapy (NRT), bupropion and varenicline] are effective treatments for smoking cessation, however, their efficacy and safety in pregnancy remains unknown. OBJECTIVES To determine the efficacy and safety of smoking cessation pharmacotherapies, including NRT, varenicline and bupropion (or any other medications) when used to support smoking cessation in pregnancy. SEARCH METHODS We searched the Pregnancy and Childbirth Group's Trials Register (5 March 2012), checked references of retrieved studies and contacted authors in the field. SELECTION CRITERIA Randomised controlled trials (RCTs) with designs that permit the independent effects of any type of NRT (e.g. patch, gum etc.) or any other pharmacotherapy on smoking cessation to be ascertained were eligible for inclusion. Trials must provide very similar (ideally identical) levels of behavioural support or cognitive behaviour therapy (CBT) to participants in active drug and comparator trial arms.The following RCT designs are considered acceptable.Placebo RCTs: any form of NRT or other pharmacotherapy, with or without behavioural support/CBT, or brief advice compared with placebo NRT and additional support of similar intensity.RCTs providing a comparison between i) behavioural support/CBT or brief advice and ii) any form of NRT or other pharmacotherapy added to behavioural support of similar (ideally identical) intensity.Parallel- or cluster-randomised design trials are eligible for inclusion. However, quasi-randomised, cross-over and within-participant designs are not eligible for inclusion due to the potential biases associated with these designs. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trials for inclusion and risk of bias and extracted data. Two assessors independently extracted data and cross checked individual outcomes of this process to ensure accuracy. The primary efficacy outcome was smoking cessation in later pregnancy (in all but one trial, at or around delivery); safety was assessed by seven birth outcomes that indicated neonatal well being and we also collated data on adherence. MAIN RESULTS Six trials of NRT enrolling 1745 pregnant smokers were included; we found no trials of varenicline or bupropion. No statistically significant difference was seen for smoking cessation in later pregnancy after using NRT as compared to control (risk ratio (RR) 1.33, 95% confidence interval (CI) 0.93 to 1.91, six studies, 1745 women). Subgroup analysis comparing placebo-RCTs with those which did not use placebos found that efficacy estimates for cessation varied with trial design (placebo RCTs, RR 1.20, 95% CI 0.93 to 1.56, four studies, 1524 women; non-placebo RCTs, RR 7.81, 95% CI 1.51 to 40.35, two studies, 221 women; P value for random-effects subgroup interaction test = 0.03). There were no statistically significant differences in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care or neonatal death between NRT or control groups. AUTHORS' CONCLUSIONS Nicotine replacement therapy is the only pharmacotherapy for smoking cessation that has been tested in RCTs conducted in pregnancy. There is insufficient evidence to determine whether or not NRT is effective or safe when used to promote smoking cessation in pregnancy or to determine whether or not using NRT has positive or negative impacts on birth outcomes. Further research evidence of efficacy and safety is needed, ideally from placebo-controlled RCTs that investigate higher doses of NRT than were tested in the included studies.

Mantzari E, Vogt F, Marteau TM. The effectiveness of financial incentives for smoking cessation during pregnancy: is it from being paid or from the extra aid? BMC Pregnancy Childbirth 2012; 12:24. [PMID: 22471787 PMCID: PMC3338379 DOI: 10.1186/1471-2393-12-24] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2011] [Accepted: 04/02/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Financial incentives appear to be effective in promoting smoking cessation in pregnancy. The mechanisms by which they might operate however, are poorly understood. The present study examines how financial incentives for smoking cessation during pregnancy may work, by exploring pregnant women’s experiences of trying to stop smoking, within and outside of a financial incentives scheme. METHODS Thirty-six (n = 36) UK-based pregnant smokers (n = 36), offered standard NHS Stop-Smoking Services, of whom twenty (n = 20) were enrolled in a financial incentives scheme for smoking cessation (n = 20) and sixteen (n = 16) were not, were interviewed about (i) their motivation to stop smoking, and (ii) the factors they perceived as influencing their quitting efforts. Framework Analysis was used to analyse the data. RESULTS Women in the two groups reported similar reasons for wanting to stop smoking during pregnancy. However, they described dissimilar experiences of the Stop-Smoking Services, which they perceived to have differentially influenced their quit attempts. Women who were incentivised reported using the services more than women who were not incentivised. In addition, they described the motivating experience of being monitored and receiving feedback on their progress. Non-incentivised women reported problems receiving the appropriate Nicotine Replacement Therapy, which they described as having a detrimental effect on their quitting efforts. CONCLUSION Women participating in a financial incentives scheme to stop smoking reported greater engagement with the Stop-Smoking Services, from which they described receiving more help in quitting than women who were not part of the scheme. These results highlight the complexity of financial incentives schemes and the intricacies surrounding the ways in which they operate to affect smoking cessation. These might involve influencing individuals’ motivation and self-regulation, changing engagement with and provision of support services, or a combination of these.

Abstract
Pregnant women with high levels of nicotine dependence are the least likely to quit smoking spontaneously during pregnancy or to benefit from smoking cessation interventions. In the general population, there is increasing evidence of a relationship between smoking, nicotine dependence, and exposure to childhood trauma. We examined the relationship of childhood trauma to several measures of nicotine dependence and evaluated whether this relationship was mediated by major depressive disorder or depressive symptom severity in pregnant smokers. Moderate to extreme levels of childhood trauma were significantly related to smoking within 5 minutes or less of waking, and to the Behavioral Choice-Melioration, Negative Reinforcement, and Tolerance subscales of the Wisconsin Inventory of Smoking Dependence Motives (WISDM-68) scale. The relationships between childhood emotional abuse and the WISDM-68 Total and Negative Reinforcement subscale were partially mediated by depressive symptoms. Results suggest that childhood trauma may be a risk factor underlying nicotine dependence in pregnant smokers. Increased understanding of the relationship of affect regulation to smoking in individuals with childhood trauma histories may aid in the development of more effective treatments of nicotine dependence for this population of smokers.

Abstract
OBJECTIVE to identify existing literature which addresses the topic of detecting, assessing and intervening when a pregnant woman who has quit smoking relapses. This literature review was conducted in the light of findings of a case-control study which suggest that a quit smoking status is associated with increased risk of late stillbirth (odds ratio 3.03, 95% confidence interval 1.27-7.24, p = 0.01). METHOD a structured review was conducted to identify literature related to quitting smoking in early pregnancy, prevalence and likelihood of relapse, possible methods for detecting smoking resumption, potential intervention strategies for the relapsed smoker and the societal burden of continuing to smoke in pregnancy. FINDINGS there is a wide variety of evidence for the effectiveness of intervention strategies aimed at assisting women to quit smoking during pregnancy. However, few studies have specifically aimed to identify strategies to assist those women who report quitting in early pregnancy to maintain that status throughout pregnancy. CONCLUSIONS in light of the results of the case-control study and this literature review, it is important that changes are made to prenatal care in order to enable midwives to better identify women who are struggling with abstinence or who resume smoking during pregnancy. IMPLICATIONS FOR PRACTICE midwives should discuss and monitor smoking status with women at every prenatal visit. If a midwife finds that a woman has relapsed into smoking, they can be offered a range of quit smoking intervention strategies, including referral to a dedicated cessation service, counselling support, alternative therapies and, perhaps, nicotine replacement therapy. Further research aimed at identifying the extent of relapse among these women and the impact this may have on pregnancy outcome is warranted. Research to ascertain the most appropriate interventions to prevent relapse is also needed.

Abstract
AIM To carry out a study designed to test an intervention to increase dental attendance in rural dentally-avoidant adolescents, to identify and recruit eligible adolescents. STUDY DESIGN AND METHODS This study used a cross-sectional design to identify eligible adolescents. A total of 2,762 adolescents (60% of the enrolled students) from junior high and senior high schools in a rural county in Washington State (USA) were given a dental examination with a light and mirror by calibrated dental examiners using WHO criteria. Parents of children with serious dental needs were urged to seek dental care for their adolescent children. They were offered the chance to enroll their child in a study comparing two programs designed to help the adolescent decide whether to seek out dental care. A second group of emancipated adolescents and young adults (aged < 26 years) receiving services at the local college and health department was also screened, and eligible individuals were also offered the chance to enroll. RESULTS AND STATISTICS Only 23 (6%) of 357 eligible junior and senior high school adolescents enrolled, compared with 24 (67%) of the 36 eligible emancipated adolescents and young adults. A second follow-up letter was sent to the 85 parents of un-enrolled adolescents with the most severe caries, offering direct assistance in obtaining dental care for their children; only 3 families responded. CONCLUSIONS This study illustrates the difficulty in engaging adolescents in their oral health and utilization of oral health interventions. The results also suggest that slightly older rural individuals are more interested in and/or able to overcome barriers to seeking out dental care. Alternative strategies are suggested for recruiting avoidant adolescents.

Abstract
OBJECTIVE The objective of this study was to evaluate a depression-focused treatment for smoking cessation in pregnant women versus a time and contact health education control. We hypothesized that the depression-focused treatment would lead to improved abstinence and reduced depressive symptoms among women with high levels of depressive symptomatology. No significant main effects of treatment were hypothesized. METHOD Pregnant smokers (N = 257) were randomly assigned to a 10-week, intensive, depression-focused intervention (cognitive behavioral analysis system of psychotherapy; CBASP) or to a time and contact control focused on health and wellness (HW); both included equivalent amounts of behavioral and motivational smoking cessation counseling. Of the sample, 54% were African American, and 37% met criteria for major depression. Mean age was 25 years (SD = 5.9), and women averaged 19.5 weeks (SD = 8.5) gestation at study entry. We measured symptoms of depression using the Center for Epidemiological Studies-Depression Scale (Radloff, 1977). RESULTS At 6 months posttreatment, women with higher levels of baseline depressive symptoms treated with CBASP were abstinent significantly more often, F(1, 253) = 5.61, p = .02, and had less depression, F(1, 2620) = 10.49, p = .001, than those treated with HW; those with low baseline depression fared better in HW. Differences in abstinence were not retained at 6 months postpartum. CONCLUSIONS The results suggest that pregnant women with high levels of depressive symptoms may benefit from a depression-focused treatment in terms of improved abstinence and depressive symptoms, both of which could have a combined positive effect on maternal and child health.

Abstract
BACKGROUND Tobacco smoking in pregnancy remains one of the few preventable factors associated with complications in pregnancy, low birthweight, preterm birth and has serious long-term health implications for women and babies. Smoking in pregnancy is decreasing in high-income countries and increasing in low- to middle-income countries and is strongly associated with poverty, low educational attainment, poor social support and psychological illness. OBJECTIVES To assess the effects of smoking cessation interventions during pregnancy on smoking behaviour and perinatal health outcomes. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (June 2008), the Cochrane Tobacco Addiction Group's Trials Register (June 2008), EMBASE, PsycLIT, and CINAHL (all from January 2003 to June 2008). We contacted trial authors to locate additional unpublished data. SELECTION CRITERIA Randomised controlled trials where smoking cessation during pregnancy was a primary aim of the intervention. DATA COLLECTION AND ANALYSIS Trials were identified and data extracted by one person and checked by a second. Subgroup analysis was conducted to assess the effect of risk of trial bias, intensity of the intervention and main intervention strategy used. MAIN RESULTS Seventy-two trials are included. Fifty-six randomised controlled trials (over 20,000 pregnant women) and nine cluster-randomised trials (over 5000 pregnant women) provided data on smoking cessation outcomes.There was a significant reduction in smoking in late pregnancy following interventions (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.93 to 0.96), an absolute difference of six in 100 women who stopped smoking during pregnancy. However, there is significant heterogeneity in the combined data (I(2) > 60%). In the trials with the lowest risk of bias, the interventions had less effect (RR 0.97, 95% CI 0.94 to 0.99), and lower heterogeneity (I(2) = 36%). Eight trials of smoking relapse prevention (over 1000 women) showed no statistically significant reduction in relapse.Smoking cessation interventions reduced low birthweight (RR 0.83, 95% CI 0.73 to 0.95) and preterm birth (RR 0.86, 95% CI 0.74 to 0.98), and there was a 53.91g (95% CI 10.44 g to 95.38 g) increase in mean birthweight. There were no statistically significant differences in neonatal intensive care unit admissions, very low birthweight, stillbirths, perinatal or neonatal mortality but these analyses had very limited power. AUTHORS' CONCLUSIONS Smoking cessation interventions in pregnancy reduce the proportion of women who continue to smoke in late pregnancy, and reduce low birthweight and preterm birth. Smoking cessation interventions in pregnancy need to be implemented in all maternity care settings. Given the difficulty many pregnant women addicted to tobacco have quitting during pregnancy, population-based measures to reduce smoking and social inequalities should be supported.

Abstract
Smoking during pregnancy not only impacts on the woman's health but that of her unborn child. Women most likely to continue smoking throughout pregnancy are generally of lower age, socio-economic status, level of education and occupational status. Women who continue to smoke during pregnancy often feel criticized by society. They feel guilt and personal conflict at not quitting. Lack of long-term positive outcomes from anti-smoking campaigns may result form ignorance surrounding socio-economically disadvantaged women's life circumstances. Current interventions often ignore the emotional and psychological stressors associated with pregnancy; they do not address the altered physiological processes that occur during pregnancy. A review of the literature pertaining to women who smoke throughout pregnancy is presented. Women want an individualised approach to smoking cessation advice, with health care workers having knowledge of the woman's social situation and viewpoints. This paper reveals that the woman's perspective has largely been ignored. Indeed health care professionals have attempted to manipulate women to stop smoking rather than engage in mutually respectful dialogue.

Smoking among pregnant women in Cantabria (Spain): trend and determinants of smoking cessation. BMC Public Health 2007; 7:65.

Abstract
Background Cantabria (Spain) has one of the highest prevalence of smoking among women of the European Union. The objectives are to assess the trend of smoking during pregnancy in a five-year period and the determinants of smoking cessation during pregnancy in Cantabria. Methods A 1/6 random sample of all women delivering at the reference hospital of the region for the period 1998–2002 was drawn, 1559 women. Information was obtained from personal interview, clinical chart, and prenatal care records. In the analysis relative risks and 95% confidence intervals were estimated. Multivariable analysis was carried out using stepwise logistic regression. Results Smoking prior to pregnancy decreased from 53.6% in 1998 to 39.4% in 2002. A decrease in smoking cessation among women smoking at the beginning of pregnancy was observed, from 37.3% in 1998 to 20.6% in 2002. The mean number of cigarettes/day (cig/d) before pregnancy remained constant, around 16 cig/d, whereas a slight trend to increase over time was seen, from 7.7 to 8.9 cig/d. In univariate analysis two variables favoured significantly smoking cessation, although they were not included in the stepwise logistic regression analysis, a higher education level and to be married. The logistic regression model included five significant predictors (also significant in univariate analysis): intensity of smoking, number of previous pregnancies, partner's smoking status, calendar year of study period (these four variables favoured smoking continuation), and adequate prenatal care (which increased smoking cessation). Conclusion The frequency of smoking among pregnant women is very high in Cantabria. As smoking cessation rate has decreased over time, a change in prenatal care programme on smoking counseling is needed. Several determinants of smoking cessation, such as smoking before pregnancy and partner's smoking, should be also addressed by community programmes.

Preschool children's health and its association with parental education and individual living conditions in East and West Germany. BMC Public Health 2006; 6:312.

Abstract
Background Social inequalities in health exist globally and are a major public health concern. This study focus on a systematic investigation into the associations between health indicators, living conditions and parental educational level as indicator of the social status of 6-year-old children living in West and East Germany in the decade after re-unification. Explanations of observed associations between parental education and health indicators were examined. Methods All boys and girls entering elementary school and living in predefined areas of East and West Germany were invited to participate in a series of cross-sectional surveys conducted between 1991 and 2000. Data of 28,888 German children with information on parental education were included in the analysis. Information about educational level of the parents, individual living conditions, symptoms and diagnoses of infectious diseases and allergies were taken from questionnaire. At the day of investigation, atopic eczema was diagnosed by dermatologists, blood was taken for the determination of allergen-specific immuno-globulin E, height and weight was measured and lung function tests were done in subgroups. Regression analysis was applied to investigate the associations between the health indicators and parental educational level as well as the child's living conditions. Gender, urban/rural residency and year of survey were used to control for confounding. Results Average response was 83% in East Germany and 71% in West Germany. Strong associations between health indicators and parental education were observed. Higher educated parents reported more diagnoses and symptoms than less educated. Children of higher educated parents were also more often sensitized against grass pollen or house dust mites, but had higher birth weights, lower airway resistance and were less overweight at the age of six. Furthermore, most of the health indicators were significantly associated with one or more living conditions such as living as a single child, unfavourable indoor air, damp housing condition, maternal smoking during pregnancy or living near a busy road. The total lung capacity and the prevalence of an atopic eczema at the day of investigation were the only health indicators those did not show associations with any of the predictor variables. Conclusion Despite large differences in living conditions and evidence that some poor health outcomes were directly associated with poor living conditions, only few indicators demonstrated poorer health in social disadvantaged children. These were in both parts of Germany increased levels of overweight, higher airway resistance and, in East Germany only, reduced height in children with lower educated parents compared to those of higher education. In both East and West Germany, higher prevalence of airway symptoms was associated with a damp housing condition, and lower birth weight, reduced height and increased airway resistance at the age of six were associated with maternal smoking during pregnancy. The latter explained to a large extent the difference in birth weight and airway resistance between the educational groups.

Abstract
OBJECTIVE Smoking during pregnancy is an important problem in the Netherlands. We tested the effectiveness of a health counseling method by midwives using a RCT. METHODS Four provinces with 42 practices including 118 midwives were randomly assigned to the experimental or control condition. Midwives in the experimental group provided brief health counseling, self-help materials on smoking cessation during pregnancy and early postpartum, and a partner booklet. Controls received routine care. The main outcome measures were 7-day abstinence, continuous abstinence, and partner smoking at 6 weeks post-intervention (T1) and 6 weeks postpartum (T2). RESULTS Multi-level analysis revealed significant differences between both conditions at T1 and T2 using intention-to-treat analysis. Nineteen percent of the experimental group reported 7-day abstinence compared to 7% of the control group at T1, and 21 and 12%, respectively, at T2. For continuous abstinence these percentages were 12% in the experimental group and 3% in the control group. The partner intervention was not successful. CONCLUSION The intervention resulted in significant effects on smoking behavior for pregnant women, but not for partner smoking. PRACTICE IMPLICATIONS The program realized short-term effects. An important precondition is that midwives need a proper training.

Abstract
Tobacco use is the leading preventable cause of death in developed countries. Millions of smokers are willing to stop, but few of them are able to do so. Clinicians should only use approaches that have demonstrated their efficacy in helping patients to stop smoking. This article summarizes the evidence-based major findings and clinical recommendations for the treatment of tobacco dependence of the French Health Products Safety Agency (AFSSAPS). Clinicians should enquire about the smoking status of each patient and provide information about health consequence of smoking and effective treatments available. These treatments include counseling (mainly individual or social support and behavioral and cognitive therapy) and pharmacological treatment with either nicotine replacement therapy (NRT) or bupropion LP. Pharmacological treatments should be used only for proven nicotine dependence, as assessed by the Fagerstrom test for Nicotine Dependence. The choice of pharmacologic treatment depends of the patient's preference and history and of the presence of contra-indications. The clinician should start with a single agent, but these treatments may be used in combination. Smoking behavior is a chronic problem that requires long-term management and follow-up. Access to intensive treatment combining pharmacological treatment and extensive behavioral and cognitive therapy should be available for highly dependent patients.

Abstract
OBJECTIVE To describe the management of tobacco withdrawal in pregnant women. STUDY DESIGN The questionnaire-based, descriptive survey included 979 post-partum women. The variables analysed included the characteristics of the mother and neonate at delivery, her smoking habits, her level of exposure to passive smoking, and the barriers to giving up smoking. The chi square test was used to analyse qualitative variables and the Students t-test for quantitative variables. RESULTS 76% of women who smoked at the start of pregnancy said that they had been asked about their tobacco consumption. However, only 16% had been asked by a clinician or midwife about their attempts to stop smoking. Seven percent were offered a specialised consultation, but only one-third attended. Seventy-six percent of women who failed to stop smoking during pregnancy had a partner who smoked compared with 63% of women who gave up. Dependency and stress during pregnancy also were lower for women who stopped smoking. CONCLUSIONS Healthcare professionals seems to offer only rudimentary care. Simple strategies to help women give up smoking are required. The partner is an important target, especially if he can be persuaded to give up at the same time.

Abstract
OBJECTIVE to describe the qualitatively different ways in which midwives make sense of how to approach women smokers. DESIGN, SETTING AND PARTICIPANTS a more person-centred national project 'Smoke-free pregnancy' has been in progress in Sweden since 1992. Using a phenomenographic approach, 24 midwives who have been regularly working in antenatal care were interviewed about addressing smoking during pregnancy. FINDINGS four different story types of how the midwives made sense of their experiences in addressing smoking in pregnancy were identified: 'avoiding', 'informing', 'friend-making', 'co-operating'. KEY CONCLUSION the midwives' story types about how they approached women who smoke illustrated the difficulties of changing from being an expert who gives information and advice to being an expert on how to enable a woman in finding out why she smoked and how to stop smoking. IMPLICATIONS FOR PRACTICE health education about smoking that is built on co-operation and dialogue was seen by the midwives as a productive way of working. The starting point should be the lay perspective of a woman, which means that her thoughts about smoking cessation are given the space to grow while she talks.

Abstract
OBJECTIVES To assess the relation between cigarette smoking during pregnancy and neonatal respiratory distress syndrome (RDS) in very preterm birth, and to analyse the differential effect of antenatal steroids on RDS among smokers and non-smokers. DESIGN A population based cohort study (the French Epipage study). SETTING Regionally defined births in France. METHODS A total of 858 very preterm liveborn singletons (27-32 completed weeks of gestation) of the French Epipage study were included in this analysis. The odds ratio for RDS in relation to smoking in pregnancy was estimated using a logistic regression to control for gestational age. The odds ratio for RDS in relation to antenatal steroids was estimated taking into account an interaction between antenatal steroids and cigarette smoking, using multiple logistic regression to control for gestational age, birthweight ratio, main causes of preterm birth, mode of delivery, and sex. RESULTS The odds ratio for RDS in relation to smoking in pregnancy adjusted for gestational age (aOR) was 0.59 (95% confidence interval (CI) 0.44 to 0.79). The aOR for RDS in relation to antenatal steroids was 0.31 (95% CI 0.19 to 0.49) in babies born to non-smokers and 0.63 (95% CI 0.38 to 1.05) in those born to smokers; the difference was significant (p = 0.04). CONCLUSIONS Cigarette smoking during pregnancy is associated with a decrease in the risk of RDS in very preterm babies. Although antenatal steroids reduce the risk of RDS in babies born to both smokers and non-smokers, the reduction is smaller in those born to smokers.

OBJECTIVES To examine the prevalence, stability, and predictors of clinically significant behavior problems in 869 preterm low birth weight (LBW) infants at 3, 5, and 8 years of age. METHODS A prospective cohort study was conducted. Clinically significant behavior problems were assessed using dichotomized total problem Child Behavior Checklist scores in LBW children at ages 3, 5, and 8 years. Baseline sociodemographic and obstetric data were collected. Maternal General Health Questionnaire performed at 40 weeks' gestation was dichotomized at a score of 12 to give a measure of maternal psychological distress. Prevalence and stability of behavior problems at ages 3, 5, and 8 were determined and potential predictors of behavior problems at age 3, 5, and 8 were examined using multiple logistic regression. RESULTS Prevalence of behavior problems remained at approximately 20% at 3, 5, and 8 years. Stability of behavior problems between different ages was approximately 50%. Significant behavior problems at ages 3, 5, and 8 were predicted by maternal psychological distress at 40 weeks (odds ratio [OR]: 1.59; 95% confidence interval [CI]: 1.21-2.09), maternal cigarette smoking during pregnancy (OR: 1.57; 95% CI: 1.20-2.04), Hispanic ethnicity (OR: 2.00; 95% CI: 1.24-3.24), and maternal age (OR: 0.97; 95% CI: 0.94-0.99). CONCLUSIONS This sample had double the prevalence of behavior problems expected in the general child population. These problems showed stability over time. Cigarette smoking in pregnancy, maternal psychological distress at 40 weeks' gestation, maternal age, and Hispanic ethnicity all were significant predictors of the development of behavior problems from ages 3 to 8. These findings have implications for health policies on smoking and postnatal depression.

Abstract
The aim of this study was to survey pregnant smokers' interest in different types of smoking cessation support. Interest in cessation support was assessed via telephone interviews with women identified as smokers at their first antenatal visit. Of 206 pregnant smokers interviewed, 87% (179/206) reported wanting to stop smoking, of whom 69% (124/179) expressed an interest in receiving help with stopping. Interest was highest for behavioural support (82%, 102/124) and self-help materials (77%, 95/124). There was a significant preference for individual versus group appointments, for 'buddying' among those not in professional/managerial occupations versus those in professional/managerial occupations, and for behavioural support among non-Caucasians versus Caucasians. These findings highlight the high level of interest expressed in support with stopping smoking among pregnant smokers. Smoking cessation services may benefit through offering a range of interventions for pregnant smokers, through considering ethnic and occupational status, and through routinely offering individual appointments.

Abstract
A cross-sectional design was used to asses whether Dutch midwives trained to use a smoking cessation counseling protocol appreciated it and could implement it in routine care. Midwives received a questionnaire after the implementation period of the effectiveness study was finished. In total, 118 midwives from 42 practices participated in the study, 69 midwives (58.5%) returned the questionnaire. To validate the results collected among midwives, clients who participated in the study were also questioned about the information they received about smoking cessation from their midwife. Experimental midwives more often reported giving the advice to quit (B=0.50, S.E.=0.24, P<0.05), setting a quit date with clients who indicated to be motivated to quit (B=1.69, S.E.=0.28, P<0.001) and discussing aftercare (B=1.10, S.E.=0.25, P<0.001). These results were confirmed by data collected among clients. This easy-to-implement program is recommended for broad dissemination. Further investigation is needed to improve the partner and postpartum component.

Abstract
OBJECTIVE To assess a "stage-of-change" oriented smoking cessation intervention for infertile and pregnant women, compared with standard of care. DESIGN Randomized controlled trial. SETTING Three university teaching hospitals in Hamilton, Ontario, Canada. PATIENT(S) Infertile women at their first visit to a tertiary referral infertility clinic (n = 94) and new patients seeking pre-natal care (n = 110) who had smoked >/= 3 cigarettes in the past six months. INTERVENTION(S) A three to five minute scripted intervention and booklet specific to the woman's "stage-of-change" in the smoking continuum, versus standard of care. Exhaled carbon-monoxide (CO) monitoring was used to validate exposure in both groups. MAIN OUTCOME MEASURE(S) Delta "stage-of-change" and rate of maintained cessation at 12 months post follow-up. RESULT(S) Intervention and control were similarly effective for infertile women: the rate of maintained cessation rose significantly from 4% to 24% over twelve months, with a mean delta "stage-of-change" 0.28. In prenatal women, neither approach was effective. Maintained cessation did not significantly change from 0 to 12 months (19% to 18%). Mean delta "stage-of-change" declined by -0.62. CONCLUSION(S) For infertile women, basic information describing the impact of smoking on fertility, along with exhaled CO monitoring and a more intensive intervention were both highly effective. In pregnant women neither approach was beneficial, with some evidence of post-partum relapse.

Abstract
Regulation of growth of the fetus and its placenta begins before pregnancy. Early in pregnancy the mother sets the rate of growth of the fetus on a trajectory, which may be modified by events later in pregnancy. Low maternal weight for height, history of previous small babies, maternal undernutrition, pregnancy disorders, e.g. pre-eclampsia, are associated with low birthweight. Maternal smoking is a major factor in developed countries; infections and undernutrition in developing countries.Recently, there has been emphasis on adverse long-term outcomes including ischaemic heart disease, hypertension and diabetes associated with poor fetal growth. Experimental studies in animals show that some of these outcomes can readily be induced by restriction of fetal growth. Progress in determining successful treatments to improve the growth of the fetus has lagged behind these epidemiological and experimental findings. However, nutrient supplements improve growth in undernourished women and smoking cessation also improves fetal size and outcome.
