Abstract
BACKGROUND AND AIMS Previous economic evaluations of smoking cessation interventions for pregnant women are limited to single components, which do not in isolation offer sufficient potential impact to address smoking cessation targets. To inform the development of more appropriate complex interventions, we (1) describe the development of the Economics of Smoking in Pregnancy: Household (ESIP.H) model for estimating the life-time cost-effectiveness of smoking cessation interventions aimed at pregnant women and (2) use a hypothetical case study to demonstrate how ESIP.H can be used to identify the characteristics of optimum smoking cessation interventions. METHODS The hypothetical intervention was based on current evidence relating to component elements, including financial incentives, partner smoking, intensive behaviour change support, cigarettes consumption and duration of support to 12 months post-partum. ESIP.H was developed to assess the life-time health and cost impacts of multi-component interventions compared with standard National Health Service (NHS) care in England. ESIP.H considers cigarette consumption, partner smoking and some health conditions (e.g. obesity) that were not included in previous models. The Markov model's parameters were estimated based on published literature, expert judgement and evidence-based assumptions. The hypothetical intervention was evaluated from an NHS perspective. RESULTS The hypothetical intervention was associated with an incremental gain in quitters (mother and partner) at 12 months postpartum of 249 [95% confidence interval (CI) = 195-304] per 1000 pregnant smokers. Over the long-term, it had an incremental negative cost of £193 (CI = -£779 to 344) and it improved health, with a 0.50 (CI = 0.36-0.69) increase in quality-adjusted life years (QALYs) for mothers, partners and offspring, with a 100% probability of being cost-effective. CONCLUSIONS The Economics of Smoking in Pregnancy: Household model for estimating cost-effectiveness of smoking cessation interventions aimed at pregnant women found that a hypothetical smoking cessation intervention would greatly extend reach, reduce smoking and be cost-effective.

Abstract
OBJECTIVE The objective of this review is to comprehensively identify and synthesize the best available evidence about the experiences of women who smoked tobacco during pregnancy or postnatally (or both) concerning their health care providers' interactions with them about their smoking. INTRODUCTION Smoking tobacco during pregnancy and postnatally continue to be important global public health challenges. Maternal smoking poses risks to the woman's general health and causes pregnancy complications and serious adverse health effects for the fetus and child. Hence, it is essential that health care providers support pregnant and postnatal women to achieve smoking cessation and not relapse. Learning about these women's experiences of health care provider interactions may inform recommendations for health care provider best practice in interpersonal approach. INCLUSION CRITERIA The participants of interest are women who smoked tobacco during pregnancy, the postnatal period, or both, with the phenomenon of interest being their experiences of health care provider interactions with them about their smoking. The context is any setting globally. Studies for consideration will have qualitative data, including any mixed methods studies. METHODS This qualitative systematic review will be conducted according to JBI methodology. Databases to be searched for published studies include CINAHL, PubMed, APA PsycINFO, Embase, Sociological Abstracts, and SocINDEX. Gray literature will be searched for unpublished studies. The authors will conduct an initial screening and then a full-text review of studies for congruence with the inclusion criteria. A critical appraisal will be performed on eligible studies and data will be extracted from included studies. Meta-aggregation will be used to yield synthesized findings, which will be assigned confidence scores. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO CRD42020178866.

Abstract
PURPOSE Smoking during pregnancy can have dire consequences for both the baby and mother. Low-income pregnant women smoke at particularly high rates. Among women who quit during pregnancy, postpartum relapse is high. This randomized control trial tested the effect of adding postpartum assistance to an existing smoking cessation program (First Breath) designed for low-income women. METHODS Of 185 study participants, 94 women were randomly assigned to the standard First Breath program (control) and 91 to an enhanced program. First Breath consisted of evidence-based smoking cessation counseling provided at every prenatal visit. The enhanced program included all First Breath services plus 4 in-home counseling visits (3 postpartum), 3 postpartum counseling calls, support to others in the home, and incentives (gift cards) totaling $100. The primary outcome was biochemically verified abstinence at 6 months postpartum. RESULTS Among the 98 women who completed the study, the abstinence rate among the intervention participants (n=41) was significantly greater than among the control participants (n=57) (36.6% vs 12.3%, respectively; P<0.01). Analyzed on an intent-to-treat basis, with those lost to follow-up assumed to be smoking, the abstinence rate among intervention subjects (n=91) was 16.5% vs 7.4% among control participants (n=94); P=0.07. CONCLUSIONS Extending smoking cessation interventions into the postpartum period may help address postpartum relapse.

Abstract
OBJECTIVES To pilot-test a Phone-based Postpartum Continuing Care (PPCC) protocol developed from existing evidence-based approaches to address both postpartum smoking relapse among low-income women who quit smoking during pregnancy and postpartum smoking increase among those who had cut down. METHODS One hundred thirty low-income pregnant women who were current or recently quit tobacco smokers were recruited at their first prenatal appointment and randomized to either a Control (standard care) or Experimental (standard care + PPCC) group. An intent-to-treat analysis was conducted on biochemically verified data from 6 in-person interviews during pregnancy and postpartum. Feasibility with regard to recruitment, randomization, assessment, and implementation of PPCC were assessed, along with acceptability among the target population. RESULTS PPCC was found to be feasible and acceptable to some participants, but not all. There were no significant differences in tobacco products per day at 6 months postpartum between groups; however, effect sizes differed at 6 weeks compared with 6 months postpartum. Similarly, there were no significant differences between groups in cessation rate (24% in each group) and past 90-day tobacco use (59 vs 55 days, for Control and Experimental groups, respectively). CONCLUSIONS The PPCC intervention did not differentially reduce tobacco use postpartum compared with a controlled comparison group, though it was found to be acceptable among a subpopulation of low-income pregnant women and feasible with regard to recruitment, randomization, assessment procedures, and implementation. Further research is needed to identify an intervention that significantly improves smoking relapse rates postpartum.

A couples-focused intervention for smoking cessation during pregnancy: The study protocol of the Quit Together pilot randomized controlled trial. Tob Prev Cessat 2018; 4:17. [PMID: 30906906 PMCID: PMC6430127 DOI: 10.18332/tpc/89926] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Revised: 04/12/2018] [Accepted: 04/13/2018] [Indexed: 11/24/2022]
Abstract
Tobacco smoking remains the leading global cause of preventable disease and death. Preconception and pregnancy smoking are high in Central and Eastern Europe. Quit Together is a partnership between a US university and a Romanian university, obstetrics and gynecology clinics in Romania, and other community partners in Romania. The objective of the Quit Together pilot study is to adapt, enhance and test the implementation feasibility and initial efficacy of an evidence-based pregnancy and postnatal couple intervention for smoking cessation in Romania. Quit Together builds on the Motivation and Problem Solving (MAPS) approach, enhanced by targeting the couples' smoking behavior and focusing on dyadic efficacy for smoking cessation. The study is an ongoing randomized controlled trial of 120 Romanian pregnant smokers and their partners. Participants are randomized to: 1) an intervention arm consisting, typically, of up to 8 prenatal and postnatal telephone counseling calls for the women and 4 for their partners, combining motivational strategies and problem-solving/coping skills to encourage the woman to quit smoking and the partner to support her decision; and 2) a control arm (usual care). The primary outcome is maternal biochemically verified smoking abstinence at 3 months postpartum. Quit Together has the potential to identify effective strategies to increase maternal smoking cessation during pregnancy and smoking abstinence after birth. If effective, Quit Together is expected to have a sustainable positive impact on the health of the child, mother and partner, and potentially reduced health system costs.

Abstract
BACKGROUND Although many women stop smoking in pregnancy, others continue, causing harm to maternal and child health. Smoking behaviour is influenced by many factors, including the role of women's significant others (SOs) and support from health-care professionals (HPs). OBJECTIVES To enhance understanding of the barriers to, and facilitators of, smoking cessation and the feasibility and acceptability of interventions to reach and support pregnant women to stop smoking. DESIGN Four parts: (1) a description of interventions in the UK for smoking cessation in pregnancy; (2) three systematic reviews (syntheses) of qualitative research of women's, SOs' and HPs' views of smoking in pregnancy using meta-ethnography (interpretative approach for combining findings); (3) semistructured interviews with pregnant women, SOs and HPs, guided by the social-ecological framework (conceptualises behaviour as an outcome of individuals' interactions with environment); and (4) identification of new/improved interventions for future testing. SETTING Studies in reviews conducted in high-income countries. Qualitative research was conducted from October 2013 to December 2014 in two mixed urban/rural study sites: area A (Scotland) and area B (England). PARTICIPANTS Thirty-eight studies (1100 pregnant women) in 42 papers, nine studies (150 partners) in 14 papers and eight studies described in nine papers (190 HPs) included in reviews. Forty-one interviews with pregnant women, 32 interviews with pregnant women's SOs and 28 individual/group interviews with 48 HPs were conducted. MAIN OUTCOME MEASURES The perceived barriers to, and facilitators of, smoking cessation in pregnancy and the identification of potential new/modified interventions. RESULTS Syntheses identified smoking-related perceptions and experiences for pregnant women and SOs that were fluid and context dependent with the capacity to help or hinder smoking cessation. Themes were analysed in accordance with the social-ecological framework levels. From the analysis of the interviews, the themes that were central to cessation in pregnancy at an individual level, and that reflected the findings from the reviews, were perception of risk to baby, self-efficacy, influence of close relationships and smoking as a way of coping with stress. Overall, pregnant smokers were faced with more barriers than facilitators. At an interpersonal level, partners' emotional and practical support, willingness to change smoking behaviour and role of smoking within relationships were important. Across the review and interviews of HPs, education to enhance knowledge and confidence in delivering information about smoking in pregnancy and the centrality of the client relationship, protection of which could be a factor in downplaying risks, were important. HPs acknowledged that they could best assist by providing support and understanding, and access to effective interventions, including an opt-out referral pathway to Stop Smoking Services, routine carbon monoxide screening, behavioural support and access to pharmacotherapy. Additional themes at community, organisational and societal levels were also identified. LIMITATIONS Limitations include a design grounded in qualitative studies, difficulties recruiting SOs, and local service configurations and recruitment processes that potentially skewed the sample. CONCLUSIONS Perceptions and experiences of barriers to and facilitators of smoking cessation in pregnancy are fluid and context dependent. Effective interventions for smoking cessation in pregnancy should take account of the interplay between the individual, interpersonal and environmental aspects of women's lives. FUTURE WORK Research focus: removing barriers to support, improving HPs' capacity to offer accurate advice, and exploration of weight concerns and relapse prevention. Interventions focus: financial incentives, self-help and social network interventions. STUDY REGISTRATION This study is registered as PROSPERO CRD42013004170.

"I Was a Full Time Proper Smoker": A Qualitative Exploration of Smoking in the Home after Childbirth among Women Who Relapse Postpartum. PLoS One 2016; 11:e0157525.

Abstract
Background Many women stop smoking during pregnancy but relapse shortly afterwards, potentially putting their infants at risk of secondhand smoke (SHS) exposure. Women who were able to stop during pregnancy may be a motivated group, receptive to making behaviour changes postpartum to protect their infant from SHS exposure. Understanding more about their experiences of relapse, and if this influences home smoking behaviours and children’s exposure to SHS in the home may help to inform intervention development to prevent infant SHS exposure. Methods Guided by interpretative phenomenological methodology we conducted and analysed nine semi-structured interviews with women who quit smoking during pregnancy, but relapsed ≤3 months postpartum. Findings Central to mothers’ accounts of their smoking behaviours during pregnancy and postpartum was their desire to be a ‘responsible mother’. Mothers described using strategies to protect their infant from SHS exposure, and held strong negative attitudes towards other smoking parents. After relapsing, mothers appeared to reposition themselves as ‘social’ or ‘occasional’ smokers rather than ‘regular’ smokers. Conclusions Findings suggest that interventions to prevent/reduce infants' home SHS exposure should build on mothers' intentions to be responsible parents. As mothers who relapse principally view themselves as ‘social’ or ‘occasional’ smokers, interventions that are highlighted as relevant for women with these types of smoking patterns may be more likely to be responded to, and, ultimately, be effective.

Abstract
AIMS In pregnant smoking cessation trial participants, to estimate (1) among women abstinent at the end of pregnancy, the proportion who re-start smoking at time-points afterwards (primary analysis) and (2) among all trial participants, the proportion smoking at the end of pregnancy and at selected time-points during the postpartum period (secondary analysis). METHODS Trials identified from two Cochrane reviews plus searches of Medline and EMBASE. Twenty-seven trials were included. The included trials were randomized or quasi-randomized trials of within-pregnancy cessation interventions given to smokers who reported abstinence both at end of pregnancy and at one or more defined time-points after birth. Outcomes were validated biochemically and self-reported continuous abstinence from smoking and 7-day point prevalence abstinence. The primary random-effects meta-analysis used longitudinal data to estimate mean pooled proportions of re-starting smoking; a secondary analysis used cross-sectional data to estimate the mean proportions smoking at different postpartum time-points. Subgroup analyses were performed on biochemically validated abstinence. RESULTS The pooled mean proportion re-starting at 6 months postpartum was 43% [95% confidence interval (CI) = 16-72%, I(2) = 96.7%] (11 trials, 571 abstinent women). The pooled mean proportion smoking at the end of pregnancy was 87% (95% CI = 84-90%, I(2) = 93.2%) and 94% (95% CI = 92-96%, I(2) = 88%) at 6 months postpartum (23 trials, 9262 trial participants). Findings were similar when using biochemically validated abstinence. CONCLUSIONS In clinical trials of smoking cessation interventions during pregnancy only 13% are abstinent at term. Of these, 43% re-start by 6 months postpartum.

Abstract
BACKGROUND An understanding of women's longitudinal patterns of smoking during the pre-conception, pregnancy and postnatal period and the factors associated with these patterns could help better inform smoking cessation services and interventions. METHODS Latent class analysis (LCA) was used to empirically identify women's smoking patterns in a sample of 10,768 mothers from the 2010 UK Infant Feeding Survey. Multinomial logistic regression was used to identify characteristics associated with these patterns. RESULTS LCA identified five distinct smoking patterns during the pre-conception, pregnancy and postnatal period: "non-smokers" (74.1% of women); "pregnancy-inspired quitters" (10.2%); "persistent smokers" (10.1%); "temporary quitters" (4.4%); and postnatal quitters (1.1%). Smoking patterns varied markedly according to socio-demographic variables and parity. After adjusting for these variables, mothers who lived during pregnancy with a partner who smoked were more likely to be temporary quitters (aOR 2.64, 95% CI 1.74-3.99) or persistent smokers (aOR 3.32, 95% CI 2.34-4.72) than pregnancy-inspired quitters. Mothers who lived during pregnancy with someone else other than a partner who smoked were more likely to be persistent smokers (aOR 2.34, 95% CI 1.38-3.97) or postnatal quitters (aOR 2.97, 95% CI 1.07-8.24) than pregnancy-inspired quitters. Mothers given information on how their partner could stop smoking if they lived during pregnancy with a smoking partner were less likely to be persistent smokers (aOR 0.42, 95% CI 0.27-0.65) than pregnancy-inspired quitters. CONCLUSION Health professionals should ask about smoking at every opportunity, and refer women who self-report as current smokers to an evidence based smoking cessation service.

Abstract
BACKGROUND Children's exposure to secondhand smoke (SHS) has been causally linked to a number of childhood morbidities and mortalities. Over 50% of UK children whose parents are smokers are regularly exposed to SHS at home. No previous review has identified the factors associated with children's SHS exposure in the home. AIM To identify by systematic review, the factors which are associated with children's SHS exposure in the home, determined by parent or child reports and/or biochemically validated measures including cotinine, carbon monoxide or home air particulate matter. METHODS Electronic searches of MEDLINE, EMBASE, PsychINFO, CINAHL and Web of Knowledge to July 2014, and hand searches of reference lists from publications included in the review were conducted. FINDINGS Forty one studies were included in the review. Parental smoking, low socioeconomic status and being less educated were all frequently and consistently found to be independently associated with children's SHS exposure in the home. Children whose parents held more negative attitudes towards SHS were less likely to be exposed. Associations were strongest for parental cigarette smoking status; compared to children of non-smokers, those whose mothers or both parents smoked were between two and 13 times more likely to be exposed to SHS. CONCLUSION Multiple factors are associated with child SHS exposure in the home; the best way to reduce child SHS exposure in the home is for smoking parents to quit. If parents are unable or unwilling to stop smoking, they should instigate smoke-free homes. Interventions targeted towards the socially disadvantaged parents aiming to change attitudes to smoking in the presence of children and providing practical support to help parents smoke outside the home may be beneficial.

Abstract
BACKGROUND Smoking cessation plays a crucial role in reducing preventable morbidity and mortality and is a recognized public-health-policy issue in many countries. Two of the most important factors that affect the efficacy of quitting smoking are motivation and the ability to cope with situations causing relapse. AIM The objective of the study reported here was to investigate former and current smokers' motivations for smoking cessation, reasons for relapse, and modes of quitting. METHODS We arranged four focus groups with 24 participants (twelve current and twelve former smokers) and eleven semi-structured interviews (five current and six former smokers) with a view to understanding and categorizing their opinions on motivations and the course and process of smoking cessation. The data were next analyzed using descriptive qualitative methods. RESULTS THREE MAIN THEMES WERE IDENTIFIED: (1) motivations to quit smoking, (2) reasons why smokers sometimes relapse, and (3) modes of quitting smoking. Within the first theme, the following six subthemes surfaced: (1) a smoking ban at home and at work due to other people's wishes and rules, (2) the high cost of cigarettes, (3) the unpleasant smell, (4) health concern, (5) pregnancy and breastfeeding, and (6) a variety of other factors. The second theme encompassed the following subthemes: (1) stress and the need to lessen it by smoking a cigarette, (2) the need to experience the pleasure connected with smoking, and (3) the smoking environment both at home and at work. Participants presented different smoking-cessation modes, but mainly they were unplanned attempts. CONCLUSION Two very important motivations for smoking cessation were a smoking ban at home and at work due to other people's wishes and rules, and the high cost of cigarettes. The most common smoking-cessation mode was a spontaneous decision to quit, caused by a particular trigger factor. Relapse causes encompassed, most notably: stress, lack of the pleasure previously obtained from smoking, and the smoking environment.

Abstract
PURPOSE To understand the experiences and processes of smoking cessation, maintenance, and relapse for pregnant and postpartum adolescents, whose perspectives and needs might be different from other age groups. METHODS We conducted in-depth semistructured interviews with 52 pregnant and postpartum adolescents using tools of grounded theory analysis. RESULTS Spontaneous smoking cessation during pregnancy was reported by most participants. This was generally explained as resulting from knowledge about the harmful effects of tobacco on the fetus, intense emotional reactions to this knowledge, or unpleasant tobacco- and pregnancy-related physical symptoms. Relapses were common, however. Most participants experienced guilt when they relapsed during pregnancy. Postpartum relapse was less fraught, as many participants no longer considered their smoking to negatively affect their infants. This was found even among adolescents who were breastfeeding. Participants who did maintain cessation postpartum typically reported support from smoke-free families and environments. CONCLUSIONS The results of this study suggest a constellation of protective factors that contribute to smoking cessation and maintenance during and after pregnancy, as well as risk factors that contribute to temporary or permanent relapses. These results can inform future research and interventions on tobacco prevention among pregnant and postpartum adolescents. Several promising strategies for intervention development are discussed.
