Abstract
Background
Increasing numbers of UK women have overweight or obese body mass index scores when they become pregnant, or gain excessive weight in pregnancy, increasing their risk of adverse outcomes. Failure to manage postnatal weight is linked to smoking, non-healthy dietary choices, lack of regular exercise and poorer longer-term health. Women living in areas of higher social deprivation are more likely to experience weight management problems postnatally.
Objectives
The objectives were to assess the feasibility of conducting a definitive randomised controlled trial to determine the clinical effectiveness and cost-effectiveness of lifestyle information and access to a commercial weight management group focusing on self-monitoring, goal-setting and motivation to achieve dietary change commencing 8–16 weeks postnatally to achieve and maintain weight management and positive lifestyle behaviour.
Design
The design was a randomised two-arm feasibility trial with a nested mixed-methods process evaluation.
Setting
The setting was a single centre in an inner city setting in the south of England.
Participants
Participants were women with body mass index scores of > 25 kg/m2 at antenatal ‘booking’ and women with normal body mass index scores (18.0–24.9 kg/m2) at antenatal booking who developed excessive gestational weight gain as assessed at 36 weeks’ gestation.
Main outcome measures
Recruitment, retention, acceptability of trial processes and identification of relevant economic data were the feasibility objectives. The proposed primary outcome was difference between groups in weight at 12 months postnatally, expressed as percentage weight change and weight loss from antenatal booking. Other proposed outcomes included assessment of diet, physical activity, smoking, alcohol consumption, body image, maternal esteem, mental health, infant feeding and NHS costs.
Results
Most objectives were achieved. A total of 193 women were recruited, 98 allocated to the intervention arm and 95 to the control arm. High follow-up rates (> 80%) were achieved to 12 months. There was an 8.8% difference in weight loss at 12 months between women allocated to the intervention arm and women allocated to the control arm (13.0% vs. 4.2%, respectively; p = 0.062); 47% of women in the intervention arm attended at least one weight management session, with low risk of contamination between arms. The greatest benefit was among women who attended ≥ 10 sessions. Barriers to attending sessions included capability, opportunity and motivation issues. Data collection tools were appropriate to support economic evaluation in a definitive trial, and economic modelling is feasible to quantify resource impacts and outcomes not directly measurable within a trial.
Limitations
The trial recruited from only one site. It was not possible to recruit women with normal body mass index scores who developed excessive pregnancy weight gain.
Conclusions
It was feasible to recruit and retain women with overweight or obese body mass index scores at antenatal booking to a trial comparing postnatal weight management plus standard care with standard care only and collect relevant data to assess outcomes. Approaches to recruit women with normal body mass index scores who gain excessive gestational weight need to be considered. Commercial weight management groups could support women’s weight management as assessed at 12 months postnatally, with probable greater benefit from attending ≥ 10 sessions. Process evaluation findings highlighted the importance of providing more information about the intervention on trial allocation, extended duration of time to commence sessions following birth and extended number of sessions offered to enhance uptake and retention. Results support the conduct of a future randomised controlled trial.

Abstract
Introduction Most women who quit smoking during pregnancy will relapse postpartum. Interventions for sustained postpartum abstinence can benefit from understanding prenatal characteristics associated with treatment response. Given that individuals with psychiatric disorders or elevated depressive symptoms have difficulty quitting smoking and that increases in depressive symptoms prenatally are common, we examined the relevance of psychiatric diagnoses, prenatal depressive symptoms, and stress to postpartum relapse prevention intervention response. Methods Pregnant women (N = 300) who quit smoking during pregnancy received intervention (with specialized focus on mood, weight, and stress [STARTS] or a comparison [SUPPORT]) to prevent postpartum relapse. As previously published, nearly one-third and one-quarter of women achieved biochemically-confirmed sustained abstinence at 24- and 52-weeks postpartum, with no difference in abstinence rates between the interventions. Women completed psychiatric interviews and questionnaires during pregnancy. Smoking was assessed in pregnancy, and 24- and 52-weeks postpartum. Results Psychiatric disorders did not predict sustained abstinence or treatment response. However, treatment response was moderated by end-of-pregnancy depressive symptoms (χ2 = 9.98, p = .002) and stress (χ2 = 6.90, p = .01) at 24- and 52-weeks postpartum and remained significant after including covariates. Women with low distress achieved higher abstinence rates in SUPPORT than in STARTS (37% vs. 19% for depressive symptoms; 36% vs. 19% for stress), with no difference for women with high symptoms. Conclusions Prenatal depressive symptoms and stress predicted differential treatment efficacy in women with low symptoms, not in women with high symptoms. Diagnostic history did not predict treatment differences. Future research to address prenatal distress may help tailor postpartum relapse prevention interventions. Implications We examined prenatal history of psychiatric disorders and psychiatric distress as moderators of response to postpartum smoking relapse prevention intervention that either included or did not include added content on mood, stress, and weight concerns. For women with lower psychiatric distress, the added focus is not necessary, as these women achieved greater sustained abstinence in the less-intensive treatment. Understanding which women need which level of care to sustain abstinence can help allocate resources for all postpartum former smokers. These findings underscore the importance of perinatal symptom monitoring and promoting behavioral health more broadly in pregnant and postpartum women.

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
IMPORTANCE Most women who quit smoking during pregnancy will relapse postpartum. Previous efforts to prevent postpartum relapse have been unsuccessful at increasing rates of sustained abstinence. OBJECTIVE To evaluate the relative efficacy of 2 different approaches to prevent postpartum smoking relapse. DESIGN, SETTING, AND PARTICIPANTS Pregnant women who recently had quit smoking were recruited before the end of pregnancy. Intervention sessions were conducted through a combination of telephone calls and in-person visits beginning at delivery and continuing through 24 weeks postpartum. Participants completed assessments at the prenatal baseline and at 12, 24, and 52 weeks postpartum. Participants were recruited between March 2008 and December 2012. The dates of the analysis were April 2014 to February 2015. INTERVENTIONS Women received postpartum-adapted, behavioral smoking relapse prevention intervention and were randomly assigned to an enhanced cognitive behavioral intervention that included additional specialized strategies and content focused on women's postpartum concerns about mood, stress, and weight (Strategies to Avoid Returning to Smoking [STARTS]) or a supportive, time and attention-controlled comparison (SUPPORT). Intervention began before delivery and continued through 24 weeks postpartum. MAIN OUTCOMES AND MEASURES The primary outcome was biochemically confirmed sustained tobacco abstinence at 52 weeks postpartum. Secondary outcomes were self-reported mood, levels of perceived stress, and degree of concern about smoking-related weight gain. RESULTS The study cohort comprised 300 participants (150 randomly assigned to each group). Their mean (SD) age was 24.99 (5.65) years. Overall, 38.0% (114 of 300), 33.7% (101 of 300), and 24.0% (72 of 300) of the sample maintained abstinence at 12, 24, and 52 weeks' postpartum, respectively. There were no differences between the intervention groups in abstinence or time to relapse. Self-reported depressive symptoms and perceived stress significantly improved over time, and improvements were similar for both intervention groups. Women with more depressive symptoms and higher levels of perceived stress were more likely to relapse (hazard ratio, 1.02; 95% CI, 1.00-1.04; P = .04 for depressive symptoms and hazard ratio, 1.04; 95% CI, 1.01-1.07; P = .003 for stress). CONCLUSIONS AND RELEVANCE An intervention designed to address women's concerns about mood, stress, and weight did not differentially improve rates of sustained tobacco abstinence postpartum compared with a time and attention-controlled comparison. Women in STARTS and SUPPORT reported postpartum improvements in mood and stress, and the experience of fewer depressive symptoms and less perceived stress was related to sustained abstinence. Given that most pregnant quitters will relapse within 1 year postpartum and that postpartum smoking has negative health consequences for women and children, effective interventions that target postpartum mood and stress are needed.

Abstract
INTRODUCTION Although expired-air carbon monoxide (CO) is a well characterized biomarker of cigarette smoking, limited research has assessed whether the standard clinical CO cutoffs need to be altered for postpartum women and whether these cutoffs remain constant across the postpartum year. Accordingly, the present study evaluated the effectiveness of using CO as a method to confirm smoking status relative to salivary cotinine among postpartum women and assessed optimal CO criteria to confirm smoking status across the postpartum year. Differences in optimal CO criteria to confirm smoking status also were examined between black and white postpartum women. METHODS Women (N = 208) for the present study had quit smoking for their current pregnancy and were enrolled in a larger postpartum relapse prevention intervention. Smoking status was assessed at 12, 24, and 52 weeks postpartum using both expired-air CO and salivary cotinine. RESULTS Receiver-operating characteristic analyses indicated that CO provided moderately high diagnostic accuracy to distinguish between women who were and were not smoking when using salivary cotinine as the reference criterion to confirm smoking status. CO cutoffs of 2 and 3 parts per million (ppm) had the highest overall efficiency and combined sensitivity and specificity across the postpartum year. Results were consistent for black and white women. CONCLUSIONS These findings indicate that optimal CO criteria to confirm smoking status remains stable throughout the postpartum year and support a need to utilize CO cutoffs much lower than the standard clinical CO criterion of 8 ppm to confirm abstinence among postpartum women. IMPLICATIONS Findings from the present study confirm the value of CO as a biomarker of smoking status among postpartum women. Results indicate that CO cutoffs of 2 and 3 ppm were optimal for confirming smoking status across the entire postpartum year in both black and white women. These findings offer a replication and extension of previous work and indicate that optimal CO criteria to confirm smoking status remain stable throughout the postpartum period and further support a need to utilize CO cutoffs much lower than the standard clinical criterion of 8 ppm to confirm smoking status among postpartum women.

Abstract
Smoking during pregnancy has been linked to a variety of adverse outcomes for both maternal and child health. Decades of studies have sought to increase cessation antepartum and reduce relapse postpartum. A number of effective interventions exist to significantly reduce smoking rates during pregnancy; however, less is known about how to prevent relapse in the postpartum period. This review investigates interventions to prevent relapse in the long-term postpartum period. We focus specifically on nonspontaneous quitters (individuals who quit smoking as a result of an external intervention) to reveal differences in long-term response to interventions for this population compared to spontaneous quitters. A systematic literature search yielded 32 relevant studies of pharmacological, behavioral, and incentives-based interventions. Results were compiled, analyzed, and compared in order to evaluate success factors in maintaining cessation postpartum. Though intervention groups showed consistently higher quit rates during pregnancy than control groups, none of the intervention types were effective at preventing relapse in the longer-term postpartum period. One study maintained significantly higher abstinence in the longer-term period postpartum using a mix of behavioral and incentives strategies. Additional research in this area is needed to identify optimal intervention strategies to reduce long-term postpartum relapse, particularly for nonspontaneous quitters.

Abstract
The majority of women who quit smoking during pregnancy relapse postpartum and many experience increased depressive symptoms and concerns about body shape and weight. Given the relationship of weight concerns and negative mood to smoking relapse, interventions designed to address the postpartum experience are indicated. However, there are several challenges to research with postpartum women. We describe the rationale of a randomized controlled trial of postpartum smoking relapse prevention intervention and discuss methods to address the specific challenges to recruiting, retaining and conducting health behavior interventions among postpartum former smokers. Pregnant women who had quit smoking for at least one month prior to the 34 week of pregnancy and who were motivated to stay quit postpartum were recruited. Women were randomized either to a postpartum specific intervention designed to address concerns about mood, stress and weight using cognitive-behavioral techniques or to a support-only condition designed to control for time and attention. Intervention continues through six months postpartum and women complete follow-up assessments at 12-, 24- and 52-weeks after delivery. Women (n=300) who had quit smoking as a result of pregnancy were recruited and are being followed. The intervention described in this report is designed to address stress, negative mood and concerns about weight that mediate smoking relapse postpartum to sustain abstinence and improve maternal and infant health.

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.

Abstract
This review considers the effectiveness of interventions to encourage the establishment of smoke-free homes during pregnancy and the neonatal period. A comprehensive search of the literature was undertaken to find relevant studies via electronic databases, citations and reference lists of included studies. The searches identified 17 papers that met the inclusion criteria. These were quality assessed and data extracted. Due to heterogeneity of the papers, a narrative synthesis was completed. Interventions were categorized in terms of those based on counselling, counselling plus additional elements, individually adapted programmes and motivational interviewing. The findings suggest inconclusive evidence relating to these intervention types, with a range of outcome measures reported. There were limitations throughout the papers in terms of study quality (especially sample size) and poor reporting of results in relation to effectiveness. The review was limited by its very specific population; however, it suggests that currently there is mixed evidence for the effectiveness of interventions to reduce parental environmental tobacco smoke in early infancy.

Abstract
BACKGROUND The majority of women who quit smoking as a result of pregnancy will resume smoking during the first 6 months postpartum. Evidence suggests that changes in depressive symptoms, perceived stress, and concerns about weight may relate to postpartum smoking relapse. PURPOSE This study was designed to prospectively evaluate the relationship of mood and weight concerns to postpartum smoking among women who quit smoking during pregnancy. METHODS Pregnant women who had quit smoking (N=183) were recruited between February 2003 and November 2006. Women completed assessments of mood (depressive symptoms, perceived stress, positive and negative affect) and weight concerns during the third trimester of pregnancy and at 6, 12, and 24 weeks postpartum. Self-reported smoking status was verified by expired-air carbon monoxide and salivary cotinine at each assessment. Cox regression analyses in which mood and weight concerns were treated as time-dependent covariates were conducted in 2007 and 2009. RESULTS By 24 weeks postpartum, 65% of women had resumed smoking. Smoking-related weight concerns increased risk of relapse, and positive affect and self-efficacy for weight management without smoking decreased risk of relapse postpartum. Moreover, after controlling for variables previously related to postpartum relapse, weight concerns remained significantly related to smoking relapse. CONCLUSIONS Smoking-related weight concerns and positive affect increase the likelihood that a woman will resume smoking postpartum. Moreover, weight concerns appear to be salient even in the context of other factors shown to affect postpartum smoking. This study suggests that interventions may need to address women's weight concerns and mood to help sustain smoking abstinence after childbirth.

Abstract
OBJECTIVE The objective of this study was to test the feasibility and acceptability of introducing an intervention to address mothers' and fathers' smoking during the postpartum hospitalization. METHODS During a 14-month period (February 2005 to April 2006), we assessed the smoking status of both parents of all newborns who were delivered at a hospital child birth center. Parents who were current smokers (1 cigarette, even a puff, in past 30 days) or recent quitters (smoked since 1 month before conception) were eligible for the study. Parents were assigned to intervention or usual care control condition on the basis of day of study enrollment. Smoking outcomes were assessed at 3 months by telephone survey and cotinine confirmation; quitline use was assessed at 3 months by using quitline database. RESULTS A total of 101 (64%) of 159 eligible parents enrolled in the study (n = 53 control subject, n = 48 intervention), including 72 (71%) current smokers and 29 (29%) recent quitters. All parents in the intervention group received the in-hospital counseling session, 94% had a fax sent to a provider, and 36 (75%) accepted quitline enrollment. In an intention-to-treat analysis that included both current smokers and recent quitters, self-reported 7-day abstinence decreased from 31% to 25% among intervention parents versus 38% to 23% among control subjects (effect size 9.4%; nonsignificant). Among current smokers at baseline who were reached at follow-up (n = 36), self-reported 24-hour quit attempts were higher in the intervention group versus control group (64% vs 18%; P = .005), whereas the cotinine-confirmed 7-day abstinence rates at follow-up were 9% in the intervention group and 3% in the control group (nonsignificant). CONCLUSIONS Enrolling mothers and fathers into tobacco treatment services during the immediate postpartum hospital stay is feasible and seems to stimulate quit attempts. The birth of an infant presents a teachable moment to reach both parents and to provide cessation assistance.

Abstract
INTRODUCTION Postpartum relapse rates are high among women who spontaneously quit smoking during pregnancy. This randomized clinical trial tested a Motivation and Problem-Solving (MAPS) treatment for reducing postpartum relapse among diverse low-income women who quit smoking during pregnancy (N = 251; 32% Black, 30% Latino, and 36% White; 55% <$30,000/year household income). METHODS Pregnant women were randomly assigned to MAPS/MAPS+ or Usual Care (UC). Continuation ratio logit models were used to examine differences in biochemically confirmed continuous abstinence at Weeks 8 and 26 postpartum by treatment group and moderators of the treatment effect. Analyses controlled for age, race/ethnicity, partner status, education, smoking rate, and the number of smokers in the participant's environment. RESULTS MAPS/MAPS+ was more efficacious than UC in the prevention of postpartum relapse (p = .05). An interaction between treatment and the number of cigarettes smoked per day before quitting approached significance (p = .09), suggesting that the MAPS/MAPS+ treatment effect was stronger among women who smoked more cigarettes per day. DISCUSSION MAPS, a holistic and dynamic approach to changing behavior using a combined motivational enhancement and social cognitive approach, is a promising intervention for postpartum smoking relapse prevention among low-income women, which may have particular relevance for women with higher prequit smoking rates.

Abstract
BACKGROUND This study examined predictors and behaviors of pregnancy-related smoking among women who belonged to a private health maintenance organization and the recall accuracy of pregnancy-related smoking behaviors after 6-years. METHODS A cohort of 725 pregnant women was followed for six years. Major predictors for smoking behavior before, during, and one-year following pregnancy were determined. In addition, accuracy of recall six years postpartum of smoking behavior at the time of pregnancy and one-year postpartum was tested. RESULTS Mother's education, asthma status, amount of pre-pregnancy smoking, gravidity, and father's smoking status were important in the prediction of pregnancy associated smoking. Agreement for recall of smoking behavior during pregnancy (6 year recall) and one-year postpartum (5 year recall) were 90% and 91%, respectively. CONCLUSIONS Despite potentially adverse outcomes, a proportion of women continue to smoke throughout pregnancy. A number of variables proved to be important predictors of pregnancy associated smoking behavior. These factors should be considered by smoking cessation programs targeting women of reproductive age. Additionally, there was substantial agreement for maternal recall at six years postpartum of smoking behavior at the time of pregnancy and one-year postpartum. This should be considered in retrospective study designs that are primarily based on maternal recall of smoking behaviors before, during, and following pregnancy.

Abstract
OBJECTIVE There has been an abundance of research evaluating prenatal and postnatal smoking abstinence programs. However, few researchers have tested postpartum relapse interventions that address secondhand smoke (SHS) exposure. Pregnant women exposed to SHS are more likely to relapse. This article explores the similarities and differences among postpartum interventions that incorporate SHS education. Generating knowledge about the components of postpartum relapse prevention interventions that do and do not achieve prolongation of abstinence is integral to the development of effective SHS interventions that help women achieve lifelong abstinence. METHODS We used a methodological review of 11 randomized, controlled trials testing the efficacy of relapse prevention interventions that address SHS exposure. We compared intervention strength, biomarker validation of home smoking and SHS, as well as abstinence and relapse rates. We examined three predictors of postpartum relapse: (1) partner smoking in the home, (2) adoption of home smoking restrictions, and (3) motivation/confidence to remain abstinent. RESULTS Findings revealed a need for more comprehensive SHS interventions and a clear delineation of abstinence/relapse terminology. Biomarker validation of home smoking and SHS was primarily measured by self-report, passive nicotine monitors, and hair nicotine levels. Furthermore, studies using nurse- and pediatrician-led interventions resulted in the lowest relapse rates. CONCLUSION A comprehensive intervention that specifically prioritizes parental education on the health effects of SHS on the family, empowerment of the mother and family members to remain abstinent and adopt a smoke-free home smoking policy, and partner influence on smoking could result in a significant reduction in postpartum relapse rates.

Abstract
While prevalence of smoking during pregnancy has declined over the past two decades, maintenance of cessation after pregnancy remains an important public health challenge, particularly for women of color. This article reports on methods for improving detection of women at risk for smoking resumption after pregnancy through the use of an evidence-based smoking assessment instrument. The instrument was adapted for use by lay health workers in a community-based maternal and infant health program. A total of 276 primarily low-income Black and Hispanic pregnant and postnatal women enrolled in the program were screened for tobacco use in an initial assessment. Of these, 190 were reassessed an average of 2.7 months later. Assessments included measures of current and past smoking and risk factors associated with relapse. Bivariate differences by smoking status were analyzed. Seventeen percent of participants who would be classified as non-smokers using less sensitive screening questions were identified as former smokers and at-risk for resuming smoking. Twenty-two percent of former smokers resumed smoking by reassessment. Smoking resumption among former smokers was associated with having a partner and household members who smoked. Identification of former smokers is critical in order to prevent resumption of smoking after pregnancy and promote long-term maternal smoking cessation. Brief assessment instruments administered at multiple points in time during the prenatal and postnatal periods are an effective means of improving detection of women at risk for smoking resumption. Former smokers should be included in prenatal and postnatal tobacco education and counseling services.

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
The authors present findings from a qualitative study on postpartum smoking among low-income women ( N = 44) who had been smokers at the onset of pregnancy. Interview data collected after delivery at Months 1, 3, and 6 postpartum are discussed to explore contextual factors contributing to smoking abstinence, relapse, and harm-reduction practices. By 6 months postpartum, 10 women (23%) had completely quit, 21 women (48%) had reduced their smoking by 50% of their prepregnancy levels, and 7 women (16%) had reduced their smoking by one third of their prepregnancy levels. Thus, the majority of the women were engaging in significant harm-reduction efforts despite being entrenched in high-risk smoking environments where they were provided with few messages to quit. Many mothers were concerned about their moral identity as a smoker and expressed concerns that their child might initiate smoking at an early age. Future programs targeting this population should acknowledge women's harm-reduction efforts in environments where smoking is normative.

Abstract
BACKGROUND While the prevalence of young female smokers is rising among the Hong Kong Chinese population, data on their smoking pattern during pregnancy are limited. AIMS To investigate the smoking habit of Hong Kong Chinese women and their partners during pregnancy. METHODS Postal questionnaires were sent to 479 couples to explore their smoking patterns during pregnancy at one to two years after the index delivery. RESULTS Questionnaires were completed by 247 subjects. Among 117 women who were ever-smokers, 26% had stopped smoking before the index pregnancy, while 60% stopped and 14% reduced smoking during the pregnancy. Most women stopped smoking in the first trimester (93%) and prior to the first antenatal visit (79%). Those who used to smoke fewer cigarettes before pregnancy were more likely to stop smoking during pregnancy but women with a history of recreational drug use were more likely to continue smoking during pregnancy. The post-partum smoking relapse rate was 59% in women who had stopped smoking before or during their pregnancy. Only 2.6% of the partners who were ever-smokers stopped smoking before the pregnancy while smoking habits remained unchanged in 52%. CONCLUSIONS Approximately one-fifth of an unselected sample of Hong Kong mothers had a history of smoking prior to pregnancy. Pregnancy is an opportune time to implement smoking intervention programs for female smokers and their partners with an emphasis on the maintenance of post-partum smoking abstinence.

Abstract
PURPOSE Most women who quit smoking during pregnancy resume smoking in the postpartum period. Interventions to improve rates of sustained tobacco abstinence postpartum may need to address psychosocial factors during the postpartum period. However, given the multiple demands on mothers of young children, it is unclear whether women will find postpartum relapse prevention treatment acceptable. We sought to determine the acceptability of a postpartum smoking relapse prevention intervention and the appeal of strategies to address concerns about mood, stress, and weight to prevent postpartum relapse. METHODS Women (n = 36) who had quit smoking during pregnancy and either remained abstinent or relapsed within the first year postpartum completed a survey about postpartum relapse prevention program modalities, topics, and barriers to treatment. The responses of women who had and had not relapsed to smoking were compared. MAIN FINDINGS Both groups endorsed the opportunity to talk with a counselor about relapse prevention, and those who had and had not relapsed did not differ in their endorsement of different treatment modalities. Discussing mood, stress, and weight concerns were endorsed by both groups of women, but those who had relapsed were more likely to endorse stress management as an intervention topic. Those who had relapsed also were more likely to endorse the use of pharmacologic aids than were those who had remained abstinent. CONCLUSIONS These data suggest that postpartum women would find a smoking relapse prevention program that includes group and individual counseling and the use of strategies to address mood, stress, and weight concerns acceptable.

Abstract
BACKGROUND Approximately 40 percent of women smokers will stop smoking cigarettes during pregnancy; however, 70 percent of those who stop will resume smoking by 6 months postpartum. This exploratory pilot study prospectively examined the timing and predictors of returning to smoking after pregnancy in a group of inner-city women who stopped smoking cigarettes during pregnancy. METHODS We interviewed women who stopped smoking just before or during their pregnancies during their postpartum hospital stay and at their infants' 2-week health supervision visits. Urine cotinine levels were measured at each interview. RESULTS Forty-nine women were interviewed during the postpartum stay and 37 women at the 2-week follow-up. At follow-up, 40.5 percent (n = 15) of women had returned to smoking. Mothers more frequently returned to smoking if they had a lower level of education, that is, high school graduate/general equivalency diploma versus some college education (13/24 vs 2/13, p < 0.04); if they had someone else in the household who smoked (14/23 vs 1/14, p < 0.003); if they were formula feeding their infant at the time of interview (14/24 vs 1/13, p < 0.005); if they discussed smoking with a doctor or nurse during pregnancy (12/20 vs 3/17, p < 0.02); and if they were African American (10/15 vs 5/22, p < 0.02). Mothers reported the primary reasons for returning to smoking were stress (53%, n= 8) and being around another smoker (40%, n= 6). CONCLUSIONS Almost one-half of the women in this pilot study who stopped smoking cigarettes during pregnancy resumed in the days immediately after delivery. These data suggest that future studies should explore the initiation of postpartum relapse prevention during the prenatal and perinatal period. Interventions may be more effective if they include strategies aimed increasing breastfeeding rates and assisting household members to stop smoking.

Abstract
OBJECTIVES Associations between subjective social status, a subjective measure of socioeconomic status, and predictors of risk for postpartum smoking were examined among 123 pregnant women (aged 18-24 years) who stopped smoking because of pregnancy. The goal was to identify how subjective social status might influence the risk for postpartum smoking and to elucidate targets for intervention. METHODS We used multiple regression equations to examine the predictive relations between subjective social status and tobacco dependence, self-rated likelihood of postpartum smoking, confidence, temptations, positive and negative affect, depression, stress, and social support. Adjusted analyses were also conducted with control for race/ethnicity, education, income, and whether participant had a partner or not (partner status). RESULTS In unadjusted and adjusted analyses, subjective social status predicted tobacco dependence, likelihood of postpartum smoking, confidence, temptations, positive affect, negative affect, and social support. Adjusted analyses predicting depression and stress approached significance. CONCLUSIONS Among young pregnant women who quit smoking because of pregnancy, low subjective social status was associated with a constellation of characteristics indicative of increased vulnerability to postpartum smoking. Subjective social status provided unique information on risk for postpartum smoking over and above the effects of race/ethnicity, objective socioeconomic status, and partner status.

Abstract
BACKGROUND Although many women quit smoking during pregnancy, most resume smoking postpartum. One factor that may be important in postpartum relapse is a pregnant woman's motivation to remain abstinent after delivery. PURPOSE We assessed motivation for postpartum abstinence among pregnant women who had quit smoking and examined the relationship of weight concerns and mood to abstinence motivation. METHODS Pregnant former smokers, recruited between February 2000 and November 2004, completed assessments of smoking, weight concerns, depressive symptoms, and perceived stress. RESULTS Sixty-five percent were highly motivated to remain abstinent postpartum. Women who were and were not motivated were similar in age, race, and nicotine dependence. However, motivated women reported more stress, greater self-efficacy for weight management, less hunger, and less smoking for weight control than did less motivated women. After controlling for intention to breast-feed, nicotine dependence, years of smoking, partner smoking, and race, self-efficacy for weight control was related to motivation to maintain postpartum abstinence. CONCLUSIONS These data suggest that weight concerns are associated with motivation for postpartum smoking abstinence, and interventions designed to prevent postpartum smoking relapse may need to target eating, weight, and shape concerns.

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
OBJECTIVE To describe factors associated with smoking status of low-income women during pregnancy and postpartum. METHODS Data from a randomized clinical trial were used to conduct separate analyses on 327 women who smoked at baseline (time at enrollment) and for whom smoking status was available at delivery, and on 109 women who reported not smoking at delivery (quit spontaneously or after study enrollment) and for whom smoking status was available at 6-months postpartum. Salivary cotinine was used to assess the accuracy of self-reported smoking status for the sample as a whole. Data were collected between May 1997 and November 2000. RESULTS 18% of the 327 baseline smokers stopped smoking before delivery. Cessation was less likely in older women, those reporting Medicaid coverage (vs. commercial or no insurance), who were at a later week of pregnancy at baseline, were more addicted, had a husband/partner who smoked, and did not receive the study intervention. 37% of the 109 women who reported not smoking at delivery maintained abstinence at 6-months postpartum. Factors associated with abstinence were later week of pregnancy at baseline and quitting spontaneously with pregnancy, while women who lived with a smoker were less likely to report abstinence. Spontaneous quitters were less likely to relapse by 6 months postpartum than women who quit smoking later in pregnancy. CONCLUSIONS Partner participation in smoking cessation programs for pregnant and postpartum women merits exploration. Lower relapse rates among spontaneous quitters indicate a need to foster an environment that encourages quitting at pregnancy.

Abstract
Parental tobacco use is a serious health issue for all family members. Child health care clinicians are in a unique and important position to address parental smoking because of the regular, multiple contacts with parents and the harmful health consequences to their patients. This article synthesizes the current evidence-based interventions for treatment of adults and applies them to the problem of addressing parental smoking in the context of the child health care setting. Brief interventions are effective, and complementary strategies such as quitlines will improve the chances of parental smoking cessation. Adopting the 5 A's framework strategy (ask, advise, assess, assist, and arrange) gives each parent the maximum chance of quitting. Within this framework, specific recommendations are made for child health care settings and clinicians. Ongoing research will help determine how best to implement parental smoking-cessation strategies more widely in a variety of child health care settings.

Abstract
OBJECTIVES To assess potential infant exposure to bupropion and its active metabolites in breast milk such as would occur during treatment to prevent post-partum relapse to tobacco use, and to compare the concentrations of bupropion in urine and saliva with plasma and breast milk. DESIGN AND SETTING Cohort study, outpatient clinical research centre. SUBJECTS Ten healthy post-partum volunteers who agreed to take bupropion for seven days, pump and discard their breast milk, and have samples of breast milk, plasma, saliva, and urine analysed. INTERVENTION Bupropion 150 mg a day for three days and then 300 mg a day for four days. MAIN OUTCOME MEASURES Concentrations of bupropion and its active metabolites (hydroxybupropion, erythrohydrobupropion, threohydrobupropion) in breast milk, plasma, saliva, and urine. Determination of average infant exposure. RESULTS The calculated average dosage of bupropion in breast milk was 6.75 microg/kg/day. Therefore, the average infant exposure is 0.14% of the standard adult dose of bupropion, corrected for the difference in body weight. Considering the sum of bupropion and its active metabolites, the average infant exposure is expected to be 2% of the standard maternal dose on a molar basis. The concentration of bupropion and its active metabolites in breast milk was not associated with age, body mass index, use of oral contraceptive pills, age of infant, or the frequency of breast feeding at the time the study was initiated. The coefficient of determination (r2) between the concentration of bupropion in breast milk and in urine was 0.77 (p < 0.01). CONCLUSIONS Bupropion and its active metabolites are present in the breast milk of lactating women. The concentrations of bupropion in breast milk and urine were highly correlated. These results indicate that the daily dose of bupropion and metabolites that would be delivered to an infant of a woman taking a therapeutic dose of bupropion is small. These results suggest that the effectiveness of bupropion to prevent post-partum relapse to tobacco use should be evaluated without excluding women who plan to breast feed.

Abstract
BACKGROUND Smoking remains one of the few potentially preventable factors associated with low birthweight, preterm birth and perinatal death. OBJECTIVES To assess the effects of smoking cessation programs implemented during pregnancy on the health of the fetus, infant, mother, and family. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Tobacco Addiction Group trials register (July 2003), MEDLINE (January 2002 to July 2003), EMBASE (January 2002 to July 2003), PsychLIT (January 2002 to July 2003), CINAHL (January 2002 to July 2003), and AUSTHEALTH (January 2002 to 2003). We contacted trial authors to locate additional unpublished data. We handsearched references of identified trials and recent obstetric journals. SELECTION CRITERIA Randomised and quasi-randomised trials of smoking cessation programs implemented during pregnancy. DATA COLLECTION AND ANALYSIS Four reviewers assessed trial quality and extracted data independently. MAIN RESULTS This review included 64 trials. Fifty-one randomised controlled trials (20,931 women) and six cluster-randomised trials (over 7500 women) provided data on smoking cessation and/or perinatal outcomes. Despite substantial variation in the intensity of the intervention and the extent of reminders and reinforcement through pregnancy, there was an increase in the median intensity of both 'usual care' and interventions over time. There was a significant reduction in smoking in the intervention groups of the 48 trials included: (relative risk (RR) 0.94, 95% confidence interval (CI) 0.93 to 0.95), an absolute difference of six in 100 women continuing to smoke. The 36 trials with validated smoking cessation had a similar reduction (RR 0.94, 95% CI 0.92 to 0.95). Smoking cessation interventions reduced low birthweight (RR 0.81, 95% CI 0.70 to 0.94) and preterm birth (RR 0.84, 95% CI 0.72 to 0.98), and there was a 33 g (95% CI 11 g to 55 g) increase in mean birthweight. There were no statistically significant differences in very low birthweight, stillbirths, perinatal or neonatal mortality but these analyses had very limited power. One intervention strategy, rewards plus social support (two trials), resulted in a significantly greater smoking reduction than other strategies (RR 0.77, 95% CI 0.72 to 0.82). Five trials of smoking relapse prevention (over 800 women) showed no statistically significant reduction in relapse. REVIEWERS' CONCLUSIONS Smoking cessation programs in pregnancy reduce the proportion of women who continue to smoke, and reduce low birthweight and preterm birth. The pooled trials have inadequate power to detect reductions in perinatal mortality or very low birthweight.

Abstract
The majority of women who quit smoking during pregnancy will resume smoking during the postpartum period. Little is known, however, about the predictors of postpartum relapses to smoking. Changes in mood and increases in concerns about weight are common during the postpartum period, and these factors may affect women's postpartum smoking behavior. In this paper, we present a model of the relationship among mood, weight concerns and postpartum smoking. Data from previous postpartum relapse prevention trials are reviewed and evidence of a connection between changes in mood and weight concerns to postpartum relapse is presented. Directions for future research on the prevention of smoking relapses during the postpartum period, and the roles of mood and weight concerns in smoking relapse are presented.

Abstract
A gestação é uma ocasião especial para a promoção da cessação do tabagismo. A preocupação com a saúde do feto gera uma motivação extraordinária na gestante. Os resultados e a relação custo-efetividade das intervenções são melhores neste grupo do que na população em geral. Os ganhos extrapolam os benefícios à saúde da mulher, pois permitem também o desenvolvimento de um feto mais saudável. O conhecimento das peculiaridades do tabagismo durante a gestação é fundamental para uma abordagem direcionada e com maior probabilidade de sucesso. Este trabalho de revisão tem o objetivo de ressaltar a extensão dos malefícios do fumo, tanto para a mulher gestante quanto para seu feto, e estimular o uso de técnicas apropriadas para a suspensão do tabagismo nesta população.

Abstract
BACKGROUND While trends in smoking prevalence during pregnancy are known, little is known about trends in quitting during pregnancy and resuming smoking after pregnancy. OBJECTIVES This study examined the trends in and correlates of quitting during pregnancy and resuming smoking after pregnancy. METHODS We used population-based random surveys of recent mothers in ten U.S. states (total of 115,000 women) conducted between 1993 and 1999. RESULTS Although the prevalence of smoking 3 months before pregnancy was stable at around 26%, quitting during pregnancy rose from 37% to 46% between 1993 and 1999. Adjusted for maternal and state characteristics, the odds of quitting during pregnancy increased 51% between 1993 and 1999 (odds ratio [OR]=1.51; 95% confidence interval [CI]=1.08-2.12). Approximately half of the women who quit smoking during pregnancy resumed smoking within 6 months postpartum. Primiparous, privately insured, college-educated women are more likely to quit and least likely to resume smoking after delivery, compared to multiparous, Medicaid-insured, and high school-educated women. Teenaged women are more likely to quit, but also more likely to resume smoking than older women. CONCLUSIONS The increase in quit rates during pregnancy is encouraging, but the lack of any change in smoking before pregnancy or in postpartum relapse rates suggests that permanent changes in maternal smoking will require additional focus.

Abstract
Studies of the influence of social support on successful smoking cessation have been based on the smoker's perceptions only. In this pilot study of 58 couples, pregnant women who had smoked in the 30 days before pregnancy and their partners reported the positive and negative support for cessation they had received (women) or provided (partners). Mean levels of the women's and partners' perceptions of support were compared, and correlations of the two reports were analyzed while controlling for the effect of the couple's smoking status. Women's and partners' reports were similar except partners reported wanting the women to stop smoking more than women perceived. Women's and partners' perceived negative support were moderately correlated (r approximately equal to .48, p approximately equal to .001). Partner-reported positive support also was associated with women's perceived negative support (r approximately equal to .30, p approximately equal to .03). These relationships remained signif cant after controllingfor partners' and women's smoking status. Generally, partners reported giving more positive and less negative support than women perceived. Results suggest the need for further examination of couples' perceptions of support and the impact on smoking cessation during pregnancy.

Abstract
STUDY OBJECTIVES To determine the effectiveness of a cotinine-feedback, behaviorally based education intervention in reducing environmental tobacco smoke (ETS) exposure and health-care utilization of children with asthma. DESIGN Randomized controlled trial of educational intervention vs usual care. SETTING The pediatric pulmonary service of a regional pediatric hospital. PARTICIPANTS ETS-exposed, Medicaid/Medi-Cal-eligible, predominantly minority children who were 3 to 12 years old and who were seen for asthma in the hospital's emergency, inpatient, and outpatient services departments (n = 87). INTERVENTION Three nurse-led sessions employing behavior-changing strategies and basic asthma education and that incorporated repeated feedback on the child's urinary cotinine level. MEASUREMENTS The primary measurements were the urinary cotinine/creatinine ratio (CCR) and the number of acute asthma medical visits. The secondary measurements were number of hospitalizations, smoking restrictions in home, amount smoked, reported exposures of children, and asthma control. RESULTS The intervention was associated with a significantly lower odds ratio (OR) for more than one acute asthma medical visit in the follow-up year, after adjusting for baseline visits (total visits, 87; OR, 0.32; p = 0.03), and a comparably sized but nonsignificant OR for one or more hospitalization (OR, 0.34; p = 0.14). The follow-up CCR measurement and the determination of whether smoking was prohibited inside the home strongly favored the intervention group (n = 51) (mean difference in CCR adjusted for baseline, -0.38; p = 0.26; n = 51) (60; OR [for proportion of subjects prohibiting smoking], 0.24; p = 0.11; n = 60). CONCLUSIONS This intervention significantly reduced asthma health-care utilization in ETS-exposed, low-income, minority children. Effects sizes for urine cotinine and proportion prohibiting smoking were moderate to large but not statistically significant, possibly the result of reduced precision due to the loss of patients to active follow-up. Improving ETS reduction interventions and understanding their mechanism of action on asthma outcomes requires further controlled trials that measure ETS exposure and behavioral and disease outcomes concurrently.

Abstract
Cigarette smoking is considered the most significant modifiable cause of adverse pregnancy outcomes in US women. Smoking cessation in pregnant patients is one of the most effective ways to reduce negative pregnancy outcomes of fetal growth retardation, preterm delivery, and perinatal mortality. Research evidence documenting the effectiveness of health care provider interventions in smoking cessation has led to the PHS recommendation to screen and counsel every patient. Materials from the PHS and NCI are available to assist health care providers in developing a brief office-based intervention. Patient materials for distribution are also available. Increased use of office-based cessation strategies, of cessation programs in community-based interventions, and of pharmacologic therapies is necessary to remedy the public health burden of fetal exposure to tobacco. Relapse prevention methods using office-based and social support systems are important to improve long-term maintenance of cessation in women who quit smoking during pregnancy.

Abstract
Two hundred fifty-six pregnant women who had quit smoking were classified into the precontemplation (PC), contemplation (C), preparation (PA), or action (A) stages of change for postpartum smoking cessation based on a 3-item algorithm assessing personal goals, self-efficacy, and smoking behavior. Logistic regression and event history analyses indicated group differences in return to smoking at 6 weeks and 3, 6, and 12 months postpartum. The percentage of women who returned to postpartum smoking was highest in the precontemplation stage and decreased with each subsequent stage, that is, at 6 weeks 83% of PCs, 64% of Cs, 35% of PAs, and 24% of As had returned to smoking. Results lend support for the stages of change for postpartum smoking abstinence. Stage-based interventions may be developed to assist women in maintaining abstinence postpartum.

Abstract
OBJECTIVE To examine the effect of a unique organisational smoking ban on female United States Navy recruits, a population with historically high smoking rates. SETTING AND DESIGN Study participants were female recruits (n = 5503) entering the Navy recruit training command between March 1996 and March 1997 (12 consecutive months). Participants completed smoking surveys at entry to recruit training (baseline) and again at graduation from training after exposure to an eight week, 24 hour a day smoking ban. Effects of the ban on baseline to graduation changes in perceptions of being a smoker were examined, and relapse rates among baseline ever smokers was assessed three months after leaving recruit training. RESULTS Among all recruits, 41.4% reported being smokers at entry (that is, reported any smoking in the 30 days before entering recruit training). As a result of the ban, there was a significant reduction (from about 41% to 25%, p < 0.001) in the percentage of all women recruits who reported themselves as smokers, a much larger change than expected had no ban been in place. Relapse at the three month follow up varied according to the type of smoker at entry into the Navy, with rates ranging from 89% relapse among baseline daily smokers to 31% among baseline experimenters. CONCLUSIONS Findings suggest that the ban provides some smokers who desire to quit with an external impetus and support to do so. However, high relapse rates indicate that more than an organisationally mandated smoking ban during recruit training is needed to help younger smokers, more regular smokers, and those who intend to continue smoking to quit after joining the Navy.

Abstract
OBJECTIVES This study assessed providers' performance of smoking cessation counseling steps with low-income pregnant and postpartum women receiving care at community health centers. METHODS WIC (Special Supplemental Nutrition Program for Women, Infants, and Children) program staff, obstetric clinicians, and pediatric clinicians at 6 community health centers were asked to complete surveys. Smoking intervention practices (performance), knowledge and attitudes, and organizational facilitators were measured. Factors associated with performance were explored with analysis of variance and regression analysis. RESULTS Performance scores differed significantly by clinic and provider type. Providers in obstetric clinics had the highest scores and those in pediatric clinics had the lowest scores. Nurse practitioners and nutritionists had higher scores than other providers. Clinic type, greater smoking-related knowledge, older age, and perception of smoking cessation as a priority were independently related to better counseling performance. CONCLUSIONS Mean performance scores demonstrated room for improvement in all groups. Low scores for performance of steps beyond assessment and advice indicate a need for emphasis on the assistance and follow-up steps of national guidelines. Providers' own commitment to helping mothers stop smoking was important.

Abstract
Maternal smoking during pregnancy is hazardous to the developing fetus and mother. Smokers should be identified and offered personalized advice and assistance, including self-help materials tailored for pregnancy. Results of a meta-analysis of 16 randomized trials with validated outcomes indicate that such intervention increases cessation by 70% in diverse populations of pregnant women. At this time, intensive counseling on multiple occasions does not appear to increase cessation.

Abstract
OBJECTIVES This study assessed the association between maternal cigarette smoking during pregnancy and the risk of invasive meningococcal disease during early childhood. METHODS Using a retrospective cohort study design, cases from an active surveillance project monitoring all invasive meningococcal disease in the metropolitan Atlanta area from 1989 to 1995 were merged with linked birth and death certificate data files. Children who had not died or acquired meningococcal disease were assumed to be alive and free of the illness. The Cox proportional hazards analysis was used to assess the independent association between maternal smoking and meningococcal disease. RESULTS The crude rate of meningococcal disease was 5 times higher for children whose mothers smoked during pregnancy than for children whose mothers did not smoke (0.05% vs 0.01%). Multivariate analysis revealed that maternal smoking (risk ratio [RR] = 2.9; 95% confidence interval [CI] = 1.5, 5.7) and a mother's having fewer than 12 years of education (RR = 2.1; 95% CI = 1.0, 4.2) were independently associated with invasive meningococcal disease. CONCLUSIONS Maternal smoking, a likely surrogate for tobacco smoke exposure following delivery, appears to be a modifiable risk factor for sporadic meningococcal disease in young children.

Abstract
OBJECTIVES This study is an evaluation of relapse prevention interventions for smokers who quit during pregnancy. METHODS Pregnant smokers at 2 managed care organizations were randomized to receive a self-help booklet only, prepartum relapse prevention, or prepartum and postpartum relapse prevention. Follow-up surveys were conducted at 28 weeks of pregnancy and at 8 weeks, 6 months, and 12 months postpartum. RESULTS The pre/post intervention delayed but did not prevent postpartum relapse to smoking. Prevalent abstinence was significantly greater for the pre/post intervention group than for the other groups at 8 weeks (booklet group, 30%; prepartum group, 35%; pre/post group, 39%; P = .02 [different superscripts denote differences at P < .05]) and at 6 months (booklet group, 26%, prepartum group, 24%; pre/post group, 33%; P = .04) postpartum. A nonsignificant reduction in relapse among the pre/post group contributed to differences in prevalent abstinence. There was no difference between the groups in prevalent abstinence at 12 months postpartum. CONCLUSIONS Relapse prevention interventions may need to be increased in duration and potency to prevent post-partum relapse.

Abstract
We evaluated the representativeness of women approached and enrolled in a brief smoking cessation intervention conducted in Planned Parenthood clinics. In this effectiveness study, regular clinic staff were trained to identify, offer participation, and counsel willing smoking clients as part of their clinic visit. Chart audits were conducted to determine the percent of clients who had smoking status identified, as well as the percent and characteristics of potentially eligible clients who were not approached. Baseline and non-participant questionnaires were analyzed to determine participation rate and characteristics of those participating versus those not participating. Smoking status was documented in 99% of charts. Seventy percent of eligible smokers were approached about study participation and 74% of those approached participated. There were no significant differences between those approached and those not approached or between those who participated versus those who did not on a host of sociodemographic variables. This project was able to approach and attract a representative sample of young, lower income women to participate in a brief, clinic-based smoking cessation program.

Abstract
BACKGROUND The purpose of this study was to describe women's smoking experience during pregnancy and postpartum. Primiparous women recruited during a randomized controlled trial to assess the effectiveness of postpartum visiting were invited to participate in a qualitative study. METHODS A semistructured protocol guided the face-to-face interview. Interviews were audiotaped and transcribed. Data were coded independently by the authors, and the final coding system for emergent themes was developed through a consensus process. RESULTS Of the 47 women invited to participate, 22 agreed to be interviewed. Three major themes emerged from the analysis: pregnancy as a context for stopping smoking, returning to smoking, and social pressures on smoking behavior. Concerns about the baby's health were cited as central reasons for stopping. Breastfeeding provided a reason for continued smoking cessation, whereas social events often demarcated a resumption of women's smoking choices. CONCLUSIONS Results provide guidance for the timing and content of interventions to prevent smoking relapse.

Abstract
OBJECTIVES A randomized trial evaluated the impact of smoking cessation interventions on point prevalence and consecutive quit rates at an Australian public prenatal clinic. METHODS Self-reports and urine cotinine tests confirmed patients' smoking status at the midpoint and end of pregnancy and 6 weeks postpartum. RESULTS At all points, validated abstinence rates were significantly higher in the experimental group than in the control group. The rate of failed biochemical validation was significantly higher in the control group than in the experimental group. CONCLUSIONS Prenatal clinic staff can significantly increase quit rates by using cognitive-behavioral strategies. Brief advice appears to be ineffective.

Abstract
PURPOSE Despite high rates of spontaneous and assisted smoking cessation during pregnancy, postpartum maintenance is disappointingly low. Predictors of return to smoking remain unclear, thus limiting the development of interventions that could protect the health of women and their children. This study followed women who had participated in a prenatal smoking cessation intervention trial and successfully stopped smoking to address two aims: (1) describe the probability of relapse in confirmed quitters during the first 6 months after the birth, and (2) identify factors that increase relapse. DESIGN Prospective design during pregnancy and retrospective report at 6 months postpartum used survival analysis with return to smoking as the dependent variable and the Cox proportional hazards regression technique. MEASURES Questionnaires were used at the first prenatal visit and telephone interviews at the 26th week of pregnancy and 6 months postpartum. Nonsmoking after the 20th week was measured by urine cotinine tests (m = 3); nonsmoking postpartum was measured by retrospective self-report. SETTING The setting was an HMO-based group practice in Los Angeles. SUBJECTS Subjects were white, black, and Hispanic women (n = 127) available for follow-up. RESULTS The proportion of the sample classified as relapsers at 6 months postpartum was 62.9%. The final model identified the following risk factors for smoking: taking puffs in late pregnancy and having friends who smoke at the first prenatal visit, less confidence in mid-pregnancy that they could maintain nonsmoking postpartum, and a partner who smokes postpartum. CONCLUSIONS Intervention should begin in late pregnancy, and smoking networks, including partner smoking, should be addressed.

Abstract
OBJECTIVE To explore the patterns of prenatal smoking among women whose first and second pregnancies ended in live births. METHODS We used population-based data to explore prenatal smoking among 14,732 white and 8968 black Georgia residents whose first and second pregnancies ended in live births during 1989-1992. Smoking status was obtained from birth certificates linked for individual mothers. Because of demographic differences, we analyzed white and black women separately. RESULTS Approximately 15% (2253) of white women and 4% (318) of black women smoked during their first pregnancy. Of those smokers, 69% (1551) of white women and 58% (184) of black women also smoked during their second pregnancy. For both white and black nonsmokers during the first pregnancy, low education was the most significant predictor of smoking during the second pregnancy, after adjusting for consistency of the father's name on the birth certificate, prenatal care, birth interval, mother's county of residence, and birth outcome. CONCLUSIONS The prevalence of smoking in this study may be low because of underreporting of prenatal smoking on birth certificates. The majority of women who smoked during their first pregnancy also smoked during their second, suggesting that these women exposed their first infant to tobacco smoke both in utero and after delivery. Practitioners should offer smoking cessation programs to women during, as well as after, pregnancy. Pediatricians should educate parents on the health risks to young children of exposure to environmental tobacco smoke and refer smoking parents to smoking cessation programs.

Abstract
To study determinants for changes in maternal smoking behaviour during and after pregnancy, questionnaire information on smoking habits was recorded in a cohort of 3710 Norwegian women during early pregnancy, at delivery, and one year later. Of 3039 cohabiting women with complete information on smoking at all three occasions 31% smoked in early pregnancy 23% in the late pregnancy and 28% one year after delivery. Among the cohabiting mothers who smoked in early pregnancy, 44% stopped during pregnancy. After adjusting for confounding factors, the odds ratio for smoking cessation among these women who had cohabitants who smoked as opposed to not smoking was 0.2 (95% CI: 0.1-0.2). Among cohabiting non-smoking women during late pregnancy the odds ratio for being a smoker one year after child birth was 3.0 (95% CI: 2.2-4.0), if their cohabitants smoked as opposed to not smoking. The women's smoking behaviour changes considerably during and after pregnancy and their cohabitants' smoking seems to be a major determinant for changes in their smoking behaviour.

Abstract
This study examined the process of change in pregnancy smoking cessation, using the stages and processes of change from the Transtheoretical Model, to compare women who stopped smoking during pregnancy with women who were in the process of smoking cessation, but were not pregnant. Differences in smoking cessation process activity and abstinence self-efficacy were hypothesized between the pregnant and nonpregnant groups of women. Study participants were 89 pregnant women who quit smoking, 28 nonpregnant women in the action stage of smoking cessation, and 92 nonpregnant women in the preparation stage. The Smoking Cessation Processes of Change Scale and the Smoking Abstinence Self-Efficacy Scale served as dependent measures. One-way MANOVA and follow-up Newman-Keuls comparisons indicated significant differences between pregnant and nonpregnant women in their levels of process activity and self-efficacy. Pregnancy smoking cessation differed dramatically from the process of nonpregnancy smoking cessation. Pregnant quitters were not engaging in experiential and behavioral processes at levels associated with the action stage of change. Low levels of process use and high efficacy indicated an externally (for the baby) motivated stopping rather than an internal, intentional process of change, which may account for high relapse rates postpartum.

Abstract
OBJECTIVE To test our hypothesis that there is an increased lability in parents' smoking behaviour after a childbirth, and to search for demographic factors associated with lability in parents' smoking behaviour. DESIGN A one month, prospective questionnaire study. SETTING Maternal and child health centres in Oslo, Norway. SAMPLE 222 families in which at least one adult was smoking were enrolled in the study. 37 families dropped out (16.7%) and 185 families completed both questionnaires. MEASUREMENTS Changes in daily smoking, smoking quantity, and practical measures to prevent passive smoking by the children, as assessed by parental reports. RESULTS Families with a child aged less than one year (infant) were more likely to make one or another positive change (quit, reduce, stop smoking indoors, stop smoking in living rooms) than families with only older children. There was a trend for families with an infant to make negative changes more often (start smoking, increase) as well. Older parents made positive changes more often than younger ones. Single parents were less likely to make positive changes. CONCLUSIONS The study indicates that there is an increased lability in parents' smoking behaviour after a childbirth.

Abstract
OBJECTIVE To investigate smoking behaviour in young families. DESIGN Cross-sectional study. SETTING Mother and child health centres in Oslo, Norway. SUBJECTS The families of 1,046 children attending the health centres for 6-weeks-, 2- or 4- year well child visits. MAIN OUTCOME MEASURES Daily smoking, smoking quantity and practical measures taken by the parents to prevent passive smoking among the children as assessed by parental reports. RESULTS In 48% of the families at least one adult was smoking. 33% of the smoking parents smoked more than ten cigarettes per day. 47% of the smoking families reported that they did not smoke indoors. CONCLUSIONS The parents were less likely to smoke if they were more than 35 years of age, had a child aged less than one year, had a spouse/co-habitee or had a long education. Smoking parents smoked less if they had a spouse/co-habitee, had a child aged less than one year or had few children. Smoking parents were more often careful and did not smoke indoors if they had a child aged less than one year, had a spouse/co-habitee, did not have a smoking spouse/co-habitee or smoked a low number of cigarettes per day.
