Postpartum Smoking Relapse After Quitting During Pregnancy: Pregnancy Risk Assessment Monitoring System, 2000-2011

Office-Based Management of Perinatal Substance Use and Substance Use Disorder for the General Obstetrician-Gynecologist

This is a review of substance use and substance use disorder in pregnancy, intended for the generalist obstetrician-gynecologist. Herein, the authors discuss legal considerations, outline definitions, review screening tools, introduce special considerations and harm reduction, caution the use of urinary toxicology testing, and touch on the screening, brief intervention, and referral to treatment model. Furthermore, the authors provide a brief overview of the prevalence, maternal and neonatal risks, and treatment approaches for commonly used substances.

Usage of digital, social and goal-setting functionalities to support health behavior change: A mixed methods study among disadvantaged women during or after pregnancy and their healthcare professionals

OBJECTIVE

We aimed to gain insight into how and to what extent social (i.e. private/group chat) and goal-setting (e.g. rewards) functionalities in digital interventions for health behavior change were used by clients and nurses in a preventive care program for disadvantaged women during or after pregnancy, and which factors influenced usage.

METHODS

We collected quantitative and qualitative data on usage of these functionalities in 'Kindle', a mHealth intervention to prepare for health behavior change.

RESULTS

We found that nurses (n = 5) and clients (n = 20) scarcely used both functionalities. They sent 862 messages in the social functionality whose security they appreciated, but habitually used WhatsApp likewise. Moreover, nurses were hesitant to let their clients interact in the group chat. Clients formulated 59 personal goals, which they found difficult to do. Nurses rewarded 846 points for clients' progress on goal attainment, but found it hard to determine how many points to reward. Clients and nurses indicated that the functionality made it more fun and easy to discuss clients' personal goals.

CONCLUSIONS

To conclude, digital, social and goal-setting functionalities were used to a limited extent by nurses and clients, and need optimization before implementation to support disadvantaged groups to change their health behavior.

Knowledge, Attitudes, and Beliefs about Relapse Prevention Research Involving Bupropion among Current and Former Pregnant Individuals Who Smoke

Introduction

While many individuals quit smoking during pregnancy, most relapse within one year postpartum. Research into methods to decrease smoking relapse postpartum has been hampered by difficulties with recruitment.

Method

We conducted individual interviews with pregnant women (N = 22) who were interested in quitting smoking while pregnant about their attitudes regarding smoking and quitting during pregnancy, clinical trial participation, and smoking cessation medication use.

Results

Participants were aware of the risks of smoking while pregnant. Many wanted to quit smoking before delivery. Few used empirically supported treatments to quit. While research was viewed positively, interest in taking on new commitments postpartum and taking a medication to prevent relapse was low. Medication concerns were evident among most participants, especially among those planning to breastfeed. Further, several women noted medication was unnecessary, as they did not believe they would relapse postpartum. Financial incentives, childcare, and fewer and/or remote visits were identified as facilitators to participating in research. However, these factors did not outweigh women's concerns about medication use and time commitments.

Conclusions

Women are aware that quitting smoking during pregnancy and remaining smoke-free postpartum are important. However, beliefs that personal relapse risk is low and that medications are dangerous reduced enthusiasm for taking medication for postpartum relapse prevention. Future medication trials should educate women about the high likelihood of relapse, prepare to answer detailed questions about risks of cessation medications, and connect with participants' clinicians. For new mothers, studies conducted remotely with few scheduled appointments would reduce barriers to participation.

Pregnant and postnatal women's experiences of interacting with health care providers about their tobacco smoking: a qualitative systematic review

OBJECTIVE

The objective of this review was twofold: (i) to comprehensively identify the best available evidence about the experiences of women who smoked tobacco during pregnancy or postnatally (or both) concerning health care providers' interactions with them about their smoking, when such interactions occurred during contact for prenatal or postnatal health care in any health care setting; and (ii) to synthesize the research findings for recommendations to strengthen health care providers' interventions regarding smoking during pregnancy and smoking during the postnatal period.

INTRODUCTION

Maternal tobacco smoking during pregnancy and maternal tobacco smoking postnatally pose serious health risks for the woman, fetus, and offspring, whereas maternal smoking cessation has beneficial health effects. Given the importance of health care providers' interactions with pregnant and postnatal women for smoking cessation care, it is essential to understand women's experiences of such interactions.

INCLUSION CRITERIA

Studies considered for this review had qualitative research findings about the experiences of women who smoked tobacco during pregnancy or postnatally (or both) in relation to health care providers' interactions with them about their smoking.

METHODS

The review was conducted using the JBI approach to qualitative systematic reviews. Published studies were sought through 6 academic databases (eg, CINAHL, MEDLINE). Unpublished studies were searched in 6 gray literature sources (eg, ProQuest Dissertations and Theses, Google Scholar). Reference lists of retrieved records were also searched. The searches occurred in October and November 2020; no country, language, or date limits were applied. Study selection involved title and abstract screening, full-text examination, and critical appraisal of all studies that met the inclusion criteria for the review. Study characteristics and research findings were extracted from the included studies. Study selection and extraction of findings were conducted by two reviewers independently; differences between reviewers were resolved through consensus. The research findings were categorized, and the categories were aggregated into a set of synthesized findings. The synthesized finding were assigned confidence scores. The categories and finalized synthesized findings were agreed upon by all reviewers.

RESULTS

The 57 included studies varied in qualitative research designs and in methodological quality (from mostly low to high). There were approximately 1092 eligible participants, and 250 credible and unequivocal research findings. The research findings yielded 14 categories and 6 synthesized findings with low to very low confidence scores. Some women who smoked tobacco during pregnancy and some women who smoked tobacco postnatally lacked supportive interactions by health care providers regarding their smoking; other women experienced supportive interactions by health care providers. Women were adversely impacted when health care providers' interactions lacked supportiveness, and were beneficially impacted when interactions were supportive. Women varied in openness to health care providers' interactions regarding their smoking, from not being receptive to being accepting, and some women wanted meaningful health care provider interactions.

CONCLUSIONS

Although confidence in the synthesized findings is low to very low, the evidence indicates that supportive health care provider interactions may facilitate positive smoking behavior change in pregnancy and postnatally. It is recommended that health care providers implement accepted clinical practice guidelines with women who smoke prenatally or postnatally, using an approach that is person-centered, emotionally supportive, engaging (eg, understanding), and non-authoritarian.

The Understanding of Maternal Smoking among Women who were Smoking or had Quit Smoking during Pregnancy

Background

Maternal tobacco smoking during pregnancy is associated with adverse health effects for the woman, fetus, and child, including such serious effects as preterm birth, low birth weight, stillbirth, and neonatal and sudden infant death. Smoking cessation during pregnancy reduces health risks.

Purpose

In order to support pregnant women to quit smoking, it is essential to know determinants of quitting smoking in pregnancy. The purpose of this research was to examine women's understanding of maternal smoking, in terms of their beliefs, in relation to quitting smoking during pregnancy.

Methods

The study was a cross-sectional survey with anonymous questionnaires. The sample consisted of 161 pregnant and postnatal women who were continuing or had continued to smoke during pregnancy or had quit smoking during pregnancy. Logistic regression was used to determine the impact of women's understanding of maternal smoking on quitting smoking in pregnancy.

Results

A large majority of the women had low to moderate understanding of maternal smoking. Those with higher levels of understanding were more likely to quit smoking during pregnancy than were those with a low level of understanding. Not having children prior to the current pregnancy or childbirth also increased the likelihood of quitting smoking during pregnancy while being without a partner combined with having a longer duration of smoking decreased the likelihood of quitting smoking during pregnancy.

Conclusion

As a modifiable factor, pregnant women's understanding of maternal smoking can be readily targeted with informational interventions in an effort to help them quit smoking.

Cardio-Obstetrics: the Next Frontier in Cardiovascular Disease Prevention

PURPOSE OF REVIEW

Internationally, cardiovascular disease (CVD) is the leading cause of death in women. With risk factors for CVD continuing to rise, early identification and management of chronic diseases such as hypertension, diabetes, and obstructive sleep apnea is necessary for prevention. Pregnancy is a natural stress test for women with risk factors who may be predisposed to CVD and offers a unique opportunity to not only recognize disease but also implement effective and long-lasting strategies for prevention.

RECENT FINDINGS

Prevention begins before pregnancy, as preconception screening, counseling, and optimization of chronic diseases can improve maternal and fetal outcomes. Throughout pregnancy, women should maintain close follow-up, continued reevaluation of risk factors, with counseling when necessary. Continued healthcare engagement during the "fourth trimester," 3 months following delivery, allows clinicians to continue monitoring the evolution of chronic diseases, encourage ongoing lifestyle counseling, and connect women with primary care and appropriate specialists if needed. Unfortunately, this postpartum period represents a major care gap, as a significant proportion of most women do not attend their scheduled visits. Social determinants of health including decreased access to care and economic instability lead to increased risk factors throughout pregnancy but particularly play a role in poor compliance with postpartum follow-up. The use of telemedicine clinics and remote monitoring may prove to be effective interventions, bridging the gap between physicians and patients and improving follow-up for at-risk women. While many clinicians are beginning to understand the impact of CVD on women, screening and prevention strategies are not often implemented until much later in life. Pregnancy creates an opportunity to begin engaging women in cardiovascular protective strategies before the development of the disease.

Tobacco Smoking during Pregnancy: Women's Perception about the Usefulness of Smoking Cessation Interventions

Tobacco consumption during pregnancy is a serious public health problem due to its negative effects on fetal development and on pregnant women's health and well-being. Thus, it is of utmost importance to plan and implement smoking cessation interventions, to prevent the negative impact of this risk factor, namely on children's health and development. This cross-sectional study aimed at exploring the perceptions and beliefs about the usefulness of smoking cessation interventions during pregnancy, in a sample of pregnant Portuguese women. The smoking use by pregnant women, as well as the risk factors associated with tobacco smoking during pregnancy, were also analyzed. The sample included 247 pregnant Portuguese women aged between 18-43-years-old (M = 30.30, SD = 5.02): 42.5% never smoked, 18.3% quit smoking before pregnancy, 19.0% quit smoking after getting pregnant and 20.2% were current smokers. The pregnant Portuguese women who smoked during pregnancy (current smokers or who quit smoking after getting pregnant) were mostly single or divorced, with lower education levels, showed a higher prevalence of clinically significant anxiety symptoms, and perceived smoking cessation interventions during pregnancy as less useful when compared to women who never smoked or quit smoking prior pregnancy. Daily or weekly smoking cessation interventions, implemented by health professionals such as doctors, nurses, or psychologists are the ones perceived as the most useful for pregnant women. These findings provide important clues for the planning of smoking cessation interventions during pregnancy, highlighting the domains that should be carefully monitored by health professionals. Specific strategies should also be used by health professionals to promote smoking cessation considering the demands of pregnancy and postpartum.

Reciprocal Associations Between Maternal Smoking Cessation and Breastfeeding

Background: Pregnancy is a motivating factor to quit smoking, but many women relapse postpartum. The underlying mechanisms and the necessary duration of breastfeeding that provide long-term protection against postpartum smoking relapse are unknown. Aims: We aimed to examine (1) associations of smoking cessation with breastfeeding initiation and duration; (2) necessary breastfeeding duration to reduce or prevent risk of postpartum smoking relapse. Methods: In this cohort study, we recruited 55 mothers, either smoking or have quit smoking, who recently delivered their baby from the Greater Buffalo area, NY, USA. Results: Quitters had a higher breastfeeding initiation rate (73.7% versus 30.8%; p = 0.029) and breastfed longer (p < 0.024) than nonquitters. Mothers who never breastfed relapsed quicker than mothers who did (p = 0.039). There was a 28% reduction in smoking relapse at 12 months postpartum for every month longer of breastfeeding duration (confounder-adjusted hazard ratio, 0.72 [95% confidence interval, 0.55-0.94]; p = 0.014). The estimated smoking relapse risk was 60.0% for nonbreastfeeding, 22.4% for 3 months of breastfeeding, 8.4% for 6 months of breastfeeding, and 1.2% for 12 months of breastfeeding. Conclusion: Smoking cessation was associated with increased breastfeeding initiation and duration. Smoking relapse risk decreased with longer breastfeeding duration, and 12 months of breastfeeding may help to prevent smoking relapse. An integrated intervention of maternal smoking cessation and breastfeeding promotion is promising to enhance both behaviors.

Cohort Study of Cannabis Use History and Perinatal Cigarette Use Among Overweight and Obese Women

OBJECTIVES

In non-pregnant populations, cannabis use and cannabis use disorder (CUD) have been linked to tobacco use and less successful quit attempts. We compared perinatal cigarette use in women across 3 groups: never used cannabis (No CU group); used cannabis but did not meet CUD criteria (CU group); history of CUD (CUD group).

METHODS

Interviews with 257 pregnant women with overweight/obesity (M age = 28 years; 52% white) were conducted for a study of eating behavior in Western Pennsylvania from 2012-2016. Tobacco use was assessed early in pregnancy (< 20 weeks gestation), late in pregnancy (34-38 weeks gestation) and 6 months postpartum. CUD was measured with the Structured Clinical Interview for DSM-IV (SCID). Data relevant to the proposed analyses were available for 252 women. Generalized mixed effect models were used to predict perinatal cigarette use based on cannabis use group, time and their interaction, adjusting for age, race, education, income, parity, and mood/anxiety disorder.

RESULTS

Forty-eight percent of participants reported prior cannabis use and 15% were diagnosed with lifetime CUD. History of cannabis use predicted cigarette smoking in early pregnancy (OR 11.12, CI 3.27-37.85), late pregnancy (OR 6.55, CI 1.70-25.27), and 6 months postpartum (OR 7.57, CI 2.72-21.07), regardless of CUD.

CONCLUSIONS

A history of CUD did not appear to confer additional risk for perinatal cigarette use. Given increasing rates of cannabis use among pregnant women, these results highlight the importance of addressing history of cannabis use in conjunction with tobacco use to improve smoking cessation efforts.

Motivational interviewing telephone counseling to increase postpartum maintenance of abstinence from tobacco

Although many women quit smoking while pregnant, rates of relapse after delivery are high. We examined the effectiveness of motivational interviewing (MI) in maintaining postpartum abstinence from smoking among pregnant women who recently quit smoking (N = 382), randomized to receive five brief MI phone counseling calls or to a prenatal and postpartum care as usual control condition. Relapse to smoking was assessed at 3, 6, and 12 months postpartum based on self-report and urine cotinine. Cox regressions compared conditions on relapse outcomes and hazard ratio of total number of MI calls was examined to probe dose-response effects. Results revealed no difference in the hazard ratio of relapse between treatment condition and no dose-response effect of total number of MI calls. Phone counseling in the prenatal and postpartum period did not facilitate maintenance of abstinence among new mothers. Considerations for future intervention development studies on relapse prevention during the postpartum period are discussed.

Pregnant and postnatal women's experiences of interacting with health care providers about their tobacco smoking: a qualitative systematic review protocol

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.

Maternal use of nicotine products and breastfeeding 3 months postpartum

AIM

We aimed to determine the prevalence of and factors associated with maternal use of nicotine products in relation to breastfeeding.

METHODS

Nicotine use 3 months postpartum was determined in the Scandinavian PreventADALL mother-child birth cohort study recruiting 1837 women from 2014 to 2016. Electronic questionnaires at 18 weeks pregnancy and 3 months postpartum provided information on snus use, smoking or other nicotine use, infant feeding and socio-economic factors. The risk of nicotine use in relation to breastfeeding was analysed with logistic regression.

RESULTS

Overall, 5.6% of women used snus (2.9%), smoked (2.7%) or both (n = 2) 3 months postpartum, while one used other nicotine products. Among the 1717 breastfeeding women, 95.1% reported no nicotine use, while 2.4% used snus, 2.5% smoked and one dual user. Compared to 3.7% nicotine use in exclusively breastfeeding women (n = 1242), the risk of nicotine use increased by partly (OR 2.26, 95% CI 1.45-3.52) and no breastfeeding (OR 4.58, 95% CI 2.57-8.21). Nicotine use before (14.5% snus, 16.4% smoking) or in pregnancy (0.2% snus, 0.4% smoking) significantly increased the risk of using nicotine during breastfeeding.

CONCLUSION

Few breastfeeding women used snus or smoked 3 months postpartum, with increased risk by nicotine use before or during pregnancy.

Negotiating cancer preventative health behaviours and adapting to motherhood: the role of technology in supporting positive health behaviours

PURPOSE

Across the UK and USA, postpartum smoking relapse rates are high, and rates of breastfeeding and physical activity are low. This project aimed to explore these interrelated health behaviours and technology use, for intervention development to support postpartum cancer prevention.

METHODS

Focus groups and interviews with 26 purposively selected women (15 in Vermont, USA and 11 in Norfolk, UK). Recruitment was from deprived areas experiencing multiple disadvantage. Qualitative data were thematically analysed from dual cultural perspectives, underpinned by the social ecological model.

RESULTS

Women negotiate interrelated lifestyle behaviours as part of managing an identity in transition, moving through stages of disturbance, adaptation, acceptance and integration towards "becoming" a new Mother. Technology was integral to women's process of engagement with mothering identities. Intersectionality underpins complex patterns of interrelated behaviour.

CONCLUSIONS

There is scope to improve electronic/digital support for postpartum women cross-nationally to promote interrelated cancer-preventative lifestyle behaviours.

Challenges Experienced by Women Who Smoke During Pregnancy or Postnatally

Maternal smoking during pregnancy and maternal smoking postnatally are important public health concerns worldwide. Smoking adversely affects the woman's general health and is causally related to pregnancy complications and serious health outcomes for the child, such as stillbirth, preterm delivery, low birth weight, and sudden infant death. The purpose of this research was to examine maternal smoking through a quantitative descriptive survey of 164 women, 120 who were pregnant and 44 who were postnatal. Women experienced barriers to quitting smoking, including dealing with stress, being exposed to smokers, not being ready to quit, not knowing how to quit, not looking for or not being able to find information about smoking or quitting smoking, and lacking adequate social and healthcare provider support. On the other hand, women revealed characteristics that suggest they might have had improved potential for quitting smoking, including having negative feelings about smoking, having cut down on smoking, smoking at a low level, having made quit attempts, thinking it would not be hard to quit smoking, being in the preparation stage of behavioral change, and thinking their healthcare providers (HCPs) would help them if they decided to quit. Taken together, those findings suggest that HCPs could offer important assistance to help women achieve smoking cessation. However, more research needs to be conducted to clarify the role and effectiveness of various HCPs in smoking cessation interventions and to identify measures to strengthen their provision of such interventions.

Factors Affecting Smoking Behaviors and Smoking Prevalence in Pregnancy and Postpartum Period of Women

Aim

This study aimed to determine the factors affecting smoking behaviors and smoking prevalence among women during pregnancy and postpartum period.

Method

This cross-sectional study was conducted between May 2012 and October 2012 on a sample of 640 women who had children aged between one and three years and who enrolled in any one of the 23 family health centers located in the province of Sivas in Turkey. The data were collected through the questionnaires created by the researchers by interviewing the participants face to face in own homes. The data obtained were analyzed using the Statistical Package for the Social Sciences Statistics 15.0 (SPSS Inc.; Chicago, IL, USA) package program and evaluated using number, percentage distribution, chi square test, logistic regression analysis and Kaplan-Meier survival analysis.

Results

Smoking prevalence was found to be 8% during pregnancy and 15.6% in the postpartum period. It was determined that 17.2% of the women smoked before their last pregnancy (n=110), more than half of the smokers quit smoking during pregnancy (n=59), and 46.4% of them continued to smoke during pregnancy. It was determined that 79.7% of the participants who quit smoking during pregnancy relapsed within the first one to three years of the postpartum period, and only 20.3% continued not to smoke. The Kaplan-Meier survival analysis showed that women who breastfed quit smoking for a significantly longer time (27.6 months) compared with those who did not breastfeed (12 months). According to the logistic regression analysis, the risk of postpartum relapse among women aged 30 years or more was 10.99-fold higher than women between the ages of 19 and 29.

Conclusion

The rate of pre-pregnancy smokers decreased in the pregnancy and increased in the postpartum period.

[Management of Resumption Risk in Postpartum for Women who Quit Smoking During Pregnancy - CNGOF-SFT Expert Report and Guidelines for Smoking Management During Pregnancy]

According to the 2016 National Perinatal Survey, 30.0 % of women smoked before pregnancy, 45.8 % quit smoking in the 1st or 2nd trimester. Many do this only for pregnancy and the risk of postpartum relapse is high (up to 82 % at 1 year). The main factors associated with postpartum abstinence are breastfeeding, not having a smoker at home, and having no symptoms of postpartum depression. No drug treatment can be recommended to prevent the smoking postpartum relapse. Only global counseling can prevent this risk.

Smoking Status and Symptoms of Depression During and After Pregnancy Among Low-Income Women

OBJECTIVE

To describe the point prevalence rates, relapse rates, smoking status, and symptoms of depression and to examine the relationship between smoking status and symptoms of depression from early pregnancy to 12 months after childbirth among low-income women.

DESIGN

Secondary data analysis.

SETTING

Data from the national Nurse-Family Partnership program.

PARTICIPANTS

Women who were enrolled in the national Nurse-Family Partnership program between 2011 and 2016 with histories of smoking 3 months before pregnancy (N = 1,554).

METHODS

We used smoking status and Edinburgh Postnatal Depression Scale scores in early pregnancy, late pregnancy, and 12 months after childbirth to identify point prevalence rates, relapse rates, smoking status, and symptoms of depression. We used chi-square and additional analyses to examine the relationship between smoking status and symptoms of depression.

RESULTS

The prevalence of smoking was 30.12% (n = 468) in early pregnancy, 24.39% (n = 379) in late pregnancy, and 50.58% (n = 786) 12 months after childbirth. Prevalence rates of a positive depression screening result were 30.31% (n = 471), 20.46% (n = 318), and 18.08% (n = 281), respectively. Smoking relapse rates were 2.45% (n = 38) during the third trimester and 27.86% (n = 433) at 12 months after childbirth. Eight distinct patterns of smoking and depression were identified. Women who smoked were significantly more likely to also have positive depression screening results during the third trimester and at 12 months after childbirth compared with nonsmoking women (OR = 1.37, 95% confidence interval [1.04, 1.81] and OR = 1.93, 95% confidence interval [1.47, 2.51], respectively).

CONCLUSION

Prevalence rates of smoking, relapse, and positive depression screening results were great in this sample of low-income women during and after pregnancy. Pivotal time points exist where the trajectory of smoking and depression screening patterns may change. It is important for smoking cessation interventions to incorporate mental health assessment and treatment.

Cognitive Behavioral and Mindfulness-Based Interventions for Smoking Cessation: a Review of the Recent Literature

PURPOSE OF REVIEW

Cigarette smoking is the primary cause of cancer and is the leading preventable cause of morbidity and mortality. Cognitive behavioral therapy (CBT) is one of the most well-established and efficacious interventions for smoking cessation. The study of mindfulness-based interventions (MBIs) has increased exponentially in recent years, showing efficacy for smoking cessation as well. This review highlights research from the past 5 years examining CBT and MBIs for smoking cessation.

RECENT FINDINGS

Both CBT and MBIs are efficacious for special populations (e.g., low SES; pregnant smokers) and have shown initial efficacy when delivered via mhealth/ehealth. CBT has shown efficacy when combined with another behavioral treatment (e.g., ACT). Continued research is needed on CBT and MBIs that have high potential for scalability. Understanding whether they are beneficial for certain populations (e.g., cancer survivors), along with determining for whom CBT vs MBIs are most effective, is also needed.

The opinions regarding smoking behaviors in the postpartum period of the women who quit smoking during pregnancy: A qualitative study

PURPOSE

Research is designed to know the opinions of women who quit smoking during pregnancy on changing smoking behaviors during the postpartum period.

DESIGN AND METHODS

Forty-seven women who quit smoking during pregnancy were included in the sample of study. Data were collected using in-depth face-to-face interview method with semistructured interview forms.

FINDINGS

Most of the reasons of women about their restarting were either individual such as the need to cope with stressful events in the family, or baby-related such as termination of breastfeeding.

PRACTICE IMPLICATIONS

Determining causes of relapse will guide nurses to develop effective intervention to reduce smoking rates in women.

Factors Associated with Electronic Cigarette Use among Young Adults: The French "Trajectoires EpidéMiologiques en POpulation" (TEMPO) Cohort Study

Background: Electronic cigarettes (e-cigarettes) are sold in France since 2010 and have rapidly become popular. However, factors associated with e-cigarette use among young adults are not well known. Methods: We used data from the 2015 French TEMPO community based cohort study, restricted to current and former smokers with data on e-cigarette use (n = 368 adults, 23-41 years). Participants completed a self-administered questionnaire including information on family status, educational attainment, occupation and type of work contract, health problems, alcohol and cannabis use, electronic cigarette use, as well as perceptions of e-cigarettes. Use of traditional tobacco was assessed in 2011 and 2015. Data were analyzed using logistic regression models. Results: Among current and former smokers, 26.9% reported lifetime e-cigarettes use and 15.2% current use. Factors associated with lifetime use were: low socioeconomic position (OR = 2.2; 95% CI = 1.2-4.2), traditional cigarette use (OR associated with smoking in 2011 and 2015 = 13.1; 95% CI = 5.2-32.6) and positive perceptions of e-cigarettes (OR = 4.4; 95% CI = 2.4-8.1) as well as asthma (OR = 2.1; 95% CI = 0.9-4.9) and overweight/obesity (OR = 2.5, 95% CI = 0.9-6.9). Factors associated with current use were traditional cigarette smoking (OR associated with smoking in 2011 and 2015 = 3.9; 95% CI= 1.3-12.2) and positive perceptions of e-cigarettes (OR =4.4; 95% CI = 2.3-8.4). Conclusions: Young adults who use e-cigarettes tend to persist in smoking traditional cigarettes. The conditions under which e-cigarette use can help individuals quit traditional tobacco products remain to be elucidated.

In utero exposure to cigarette smoke and effects across generations: A conference of animals on asthma

BACKGROUND

The prevalence of asthma and chronic obstructive pulmonary disease (COPD) has risen markedly over the last decades and is reaching epidemic proportions. However, underlying molecular mechanisms are not fully understood, hampering the urgently needed development of approaches to prevent these diseases. It is well established from epidemiological studies that prenatal exposure to cigarette smoke is one of the main risk factors for aberrant lung function development or reduced fetal growth, but also for the development of asthma and possibly COPD later in life. Of note, recent evidence suggests that the disease risk can be transferred across generations, that is, from grandparents to their grandchildren. While initial studies in mouse models on in utero smoke exposure have provided important mechanistic insights, there are still knowledge gaps that need to be filled.

OBJECTIVE

Thus, in this review, we summarize current knowledge on this topic derived from mouse models, while also introducing two other relevant animal models: the fruit fly Drosophila melanogaster and the zebrafish Danio rerio.

METHODS

This review is based on an intensive review of PubMed-listed transgenerational animal studies from 1902 to 2018 and focuses in detail on selected literature due to space limitations.

RESULTS

This review gives a comprehensive overview of mechanistic insights obtained in studies with the three species, while highlighting the remaining knowledge gaps. We will further discuss potential (dis)advantages of all three animal models.

CONCLUSION/CLINICAL RELEVANCE

Many studies have already addressed transgenerational inheritance of disease risk in mouse, zebrafish or fly models. We here propose a novel strategy for how these three model organisms can be synergistically combined to achieve a more detailed understanding of in utero cigarette smoke-induced transgenerational inheritance of disease risk.

Experiences and cessation needs of Indigenous women who smoke during pregnancy: a systematic review of qualitative evidence

OBJECTIVES

The aim of this review was to identify and synthesize the best available evidence to address two questions: i) what is the experience of smoking during pregnancy for Indigenous women? and ii) what are the smoking cessation needs of Indigenous women who smoke during pregnancy?

INTRODUCTION

Smoking during pregnancy not only affects pregnant women's general health but also causes such serious problems as pre-term delivery, low birth weight, and sudden infant death. Rates of smoking during pregnancy are particularly high among Indigenous women. Learning about Indigenous women's experiences of smoking during pregnancy and associated smoking cessation needs is important to providing informed health care to them.

INCLUSION CRITERIA

The participants of interest were Indigenous women who smoked during a current or past pregnancy. The phenomena of interest were the experiences of smoking during pregnancy for Indigenous women and the smoking cessation needs of Indigenous women during pregnancy. The context was any community worldwide where pregnant Indigenous women live. Studies considered for this review were those in which qualitative data were gathered and analysed on the phenomena of interest, including mixed methods research.

METHODS

A comprehensive search was conducted for published studies in academic databases (i.e. PubMed, CINAHL, PsycINFO, Embase, Sociological Abstracts, SocINDEX, and Web of Science), unpublished studies in sources of gray literature (i.e. ProQuest Dissertations and Theses, OAIster, LILACS, MedNar, Google, Google Scholar, OpenGrey and relevant websites), and any additional studies in reference lists. Language and date limiters were not applied. The searches included all studies globally and were carried out on October 31, 2016. Studies that met the inclusion criteria were assessed for methodological quality by two reviewers independently, using the criteria of the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Qualitative Research. Descriptive details of each study accepted for this review were extracted in accordance with the elements of the JBI Data Extraction Form for Qualitative Research. The research findings that were relevant to the phenomena of interest and had participant voice were extracted from each included study and synthesized using the JBI meta-aggregative approach. The synthesized findings were assigned confidence scores in accordance with the JBI ConQual approach.

RESULTS

Thirteen studies were included in this review following careful consideration of the methodological quality of each study. The studies yielded a total of 116 research findings, which were grouped into 19 categories and then aggregated to form five synthesized findings. Confidence in the findings was determined to be low to very low (see ConQual Summary of Findings).

CONCLUSION

There is a small body of research evidence on Indigenous women's experiences of smoking during pregnancy and their smoking cessation needs. Confidence in the synthesized findings is constrained due to methodological limitations in many of the primary studies included in this review, along with mixed credibility of the research findings from across primary studies.

Addressing Postpartum Smoking Relapse Among Low-Income Women: A Randomized Control Trial

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.

A Pilot Randomized Controlled Trial of a Phone-based Intervention for Smoking Cessation and Relapse Prevention in the Postpartum Period

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.

Dropout and Abstinence Outcomes in a National Text Messaging Smoking Cessation Intervention for Pregnant Women, SmokefreeMOM: Observational Study

Background

Population-level text messaging smoking cessation interventions may reduce racial and ethnic differences in smoking among pregnant women.

Objective

Our objective was to examine racial and ethnic differences in dropout, response, and abstinence rates among users of a US national, publicly available text messaging cessation intervention targeting pregnant women, SmokefreeMOM.

Methods

Participants were online subscribers to SmokefreeMOM who set a prospective quit date within the 9 months before their due date. We examined demographics, smoking frequency, number of cigarettes smoked per day, and prequit time (up to 14 days of preparation time before quit date) as correlates of response rate and abstinence at 8 time points: quit date, day 7, day 14, day 21, day 28, day 35, day 42 (intervention end), and day 72 (1-month follow-up). We conducted survival analysis of time from quit date to dropout by race and ethnicity.

Results

The mean age of the analytic sample of 1288 users was 29.46 (SD 7.11) years. Of these, 65.81% (848/1288) were white, 16.04% (207/1288) were black, 8.86% (114/1288) were Latina, and 9.29% (120/1288) were multiracial, American Indian/Alaska Native, Native Hawaiian Pacific Islander, or other; 82.68% (1065/1288) had some college education or less. Point-prevalence abstinence was 14.51% (157/1082) on quit day, 3.51% (38/1082) at intervention end, and 1.99% (21/1053) at 1-month follow-up. Black users (hazard ratio 0.68, 95% CI 0.51-0.91) and those with a high school degree or less (hazard ratio 0.66, 95% CI 0.49-0.89) or some college education (hazard ratio 0.75, 95% CI 0.57-0.99) were less likely to drop out than whites or users with a bachelor’s degree or higher. Response and abstinence rates were similar across race, ethnicity, and education.

Conclusions

Enrollment was low among racial and ethnic minority women but high among less-educated women. Abstinence at intervention end and 1-month follow-up was lower than that in controlled trials of text messaging cessation interventions for pregnant women (range 7%-20%). Increasing the reach, engagement, and effectiveness of SmokefreeMOM, especially among women with high rates of smoking during pregnancy, must be prioritized.

Postpartum Tobacco Use and Perceived Stress among Alaska Native Women: MAW Phase 4 Study

Prior research explored reasons for tobacco use among pregnant Alaska Native (AN) women but did not address the postpartum period. This study followed up with AN women one to three years postpartum who had participated in a prenatal smoking cessation intervention study (Motivate Alaska Women (MAW) Phase 3) and had consented to be re-contacted for future studies. Of 47 eligible women, 32 (68%) participated. A semi-structured phone interview was conducted a mean of 2.0 years after delivery (range 1.6-2.8). Measures assessed self-reported tobacco use status in the 12 months after delivery, at 12 months postpartum, and at the time of the interview; reasons for maintaining abstinence, continued use, or relapse; and included the Perceived Stress Scale (PSS) and Negative Affect (NA) scale. Content analysis was used to generate themes from open-ended response items. Tobacco use was reported by 23 women (72%) at delivery, 30 (94%) within the 12 months after delivery, 27 (84%) at 12 months postpartum, and 29 (91%) at the time of the interview. Among nine women not using tobacco at delivery, seven (78%) relapsed during the 12 months after delivery. Of the 29 current tobacco users, 28 (97%) smoked cigarettes. Twenty-seven participants (84%) reported stress and 15 (52%) indicated addiction as reasons for continuing, starting, or resuming tobacco use. Types of stressors were related to parenting and traumatic experiences. Among current tobacco users, mean NA score (18.7) was significantly higher (p = 0.01) than the normative mean (14.8), but no differences were detected for PSS score. In this sample of AN women, postpartum tobacco use was highly prevalent, and stress was a primary reason that women endorsed for using tobacco. These preliminary results have several practice and research implications for exploring ways to support non-tobacco use among postpartum AN women.

Anxiety and depression symptoms among pregnant women with different smoking habits

Smoking during pregnancy is a major public health issue. The aim of this study isto describe the smoking habits of women during pregnancy and its association with clinically significant depressive and anxiety symptoms. 382 women answered to a socio-demographic questionnaire, the Hospital Anxiety Depression Scale (HADS) and the Edinburgh Postnatal Depression Scale (EPDS) at 33 weeks of gestation. Among pregnant woman, 284 are non-smokers, 38 are smokers and 60 quitted smoking during pregnancy. There was a significant association between maternal smoking status and marital status, education level and family income per month. Among smokers, the rate of quitters was quite similar among partnered and unpartnered women and higher in women with university degree and with higher family monthly income.  There was a significant association between maternal smoking status and clinically significant anxious symptoms [χ2(2)=8.535, p=0.014].  Among mothers with non-university education, smokers are more likely to have clinically significant anxiety symptoms than quitters (53.6% vs 24.3%) while among mothers in higher income families, smokers are more likely to have clinically significant depressive symptoms than quitters (100% vs 11.1%). This study provides important data to inform effective public health strategies directed to pregnant women.

Smoke-Free Moms: Financial Rewards for Smoking Cessation by Low-Income Rural Pregnant Women

INTRODUCTION

Maternal smoking places the child at risk during pregnancy and postpartum. Most women who quit smoking do so early when they first learn of pregnancy. Few low-income women quit once they enter prenatal care. The purpose of this study is to test in a clinical prenatal care setting the effectiveness of the Smoke-Free Moms intervention, which provides pregnant women a series of financial incentives for smoking cessation.

STUDY DESIGN

A prospective nonrandomized controlled trial that collected control population data of smoking-cessation rates at each clincal visit during pregnancy and postpartum with usual smoking counseling in 2013-2014. In 2015-2016, the same data were collected during the implementation of the Smoke-Free Moms intervention of financial incentives. Data analysis occurred in 2017.

SETTING/PARTICIPANTS

Women who were smoking at the first prenatal visit at four federally qualified health centers in rural New Hampshire.

INTERVENTION

All women received 5A's smoking counseling from clinic staff. At each clinic visit, with point-of-care confirmed negative urinary cotinine, intervention women received gift cards.

MAIN OUTCOME MEASURES

Cotinine confirmed smoking cessation without relapse: (1) during pregnancy and (2) smoking cessation in both pregnancy and postpartum.

RESULTS

Of 175 eligible pregnant women enrolled, 134 women were followed to the postpartum visit (Intervention n=66, Control n=68). The quit rates during pregnancy did not differ between groups (Intervention 36.4%, Control 29.4%, p=0.46). However, significantly more intervention mothers quit and continued as nonsmokers postpartum (Intervention 31.8%, Control 16.2%, p=0.04). In a logistic regression model including baseline sociodemographic, depressed mood, stress, and readiness to quit items, confidence in being able to quit predicted both cessation outcomes. The financial incentive intervention was an independent predictor of cessation in pregnancy through postpartum.

CONCLUSIONS

Financial incentives with existing smoking-cessation counseling by staff in low-income clinical prenatal programs led to cessation that continued during the postpartum period. Further study in larger populations is indicated.

Call to Action to Reduce Tobacco Use During Pregnancy

Tobacco use is a leading preventable cause of adverse maternal and child health outcomes. However, many women in the United States still report smoking during the third trimester of pregnancy. Smoking rates during pregnancy are particularly high among vulnerable women, such as those who experience mental illness, substance use disorder, homelessness, or interpersonal violence. The Tobacco Control Vaccine is a model based on population-level, evidence-based practices to reduce tobacco use. The four elements of the Tobacco Control Vaccine are access to treatment for tobacco dependence, smoke-free policies, increased tobacco taxes, and media campaigns. The purpose of this commentary is a call to action for health care providers to advocate for increased access to treatment for tobacco dependence; stay up-to-date on innovative, tailored treatment practices; and advocate for comprehensive, smoke-free policies, higher tobacco taxes, and media campaigns to help pregnant women quit smoking and avoid relapse in the postpartum period.

Epigenetic impacts of maternal tobacco and e-vapour exposure on the offspring lung

In utero exposure to tobacco products, whether maternal or environmental, have harmful effects on first neonatal and later adult respiratory outcomes. These effects have been shown to persist across subsequent generations, regardless of the offsprings' smoking habits. Established epigenetic modifications induced by in utero exposure are postulated as the mechanism underlying the inherited poor respiratory outcomes. As e-cigarette use is on the rise, their potential to induce similar functional respiratory deficits underpinned by an alteration in the foetal epigenome needs to be explored. This review will focus on the functional and epigenetic impact of in utero exposure to maternal cigarette smoke, maternal environmental tobacco smoke, environmental tobacco smoke and e-cigarette vapour on foetal respiratory outcomes.

Perinatal Navigator Approach to Smoking Cessation for Women With Prevalent Opioid Dependence

Women who smoke during pregnancy face psychosocial barriers to cessation, and women with opioid use disorder (OUD) face amplified barriers. We pilot tested a Perinatal Wellness Navigator (PWN) program for a group of high-risk perinatal women (N = 50; n = 42 with OUD) that consisted of (a) one-on-one tobacco treatment, (b) comprehensive assessment of cessation barriers, and (c) linkage to clinical/social services. Outcome measures were assessed at baseline and postintervention. Participants smoked 10 fewer cigarettes per day (p = .05) at postintervention and were less dependent on nicotine (p < .01). Mean postnatal depression scores (p = .03) and perceived stress (p = .03) decreased postintervention. Participants received at least one referral at baseline (n = 106 total), and 10 participants received an additional 18 referrals at postintervention to address cessation barriers. The PWN program was minimally effective in promoting total tobacco abstinence in a high-risk group of perinatal women, but participants experienced reductions in cigarettes smoked per day, nicotine dependence, stress, and depression.

Stressful life events are associated with perinatal cigarette smoking

Perinatal smoking, including smoking during pregnancy and postpartum smoking relapse, is a persistent public health problem. While childhood trauma has been linked to perinatal smoking, less is known about the association with more proximal stressful life events (SLEs). The objective of this study was to examine the association between SLEs that occurred during the year prior to childbirth with perinatal smoking. Using the Pregnancy Risk Assessment Monitoring System 2009-2011, perinatal smoking was assessed at three time points: (1) three months prior to pregnancy, (2) the last three months of pregnancy, and (3) two to six months postpartum. Survey respondents endorsed up to 13 SLEs (i.e., death of someone close). SLEs were analyzed individually, as well as using a cumulative score (range 0-13). Weighted analyses included unadjusted and adjusted logistic regression. Among those who smoked prior to pregnancy (n = 15,316), 48% (n = 7308) reported quitting smoking during pregnancy. Of those, 44% (n = 3126) reported postpartum smoking relapse. A total of 11 SLEs were associated with smoking during pregnancy and 2 SLEs were associated with postpartum smoking relapse. The odds of continued smoking during pregnancy was 12% higher for each SLE endorsed (adjusted odds ratio [aOR] = 1.12, 95% confidence interval [CI]: 1.09, 1.15) and this association was attenuated in relation to the odds of postpartum smoking relapse (aOR = 1.03, 95% CI: 0.99, 1.08). SLEs are associated with perinatal smoking. Additional research is needed to elucidate the mechanisms of action and to develop interventions specific to the needs of women who experience SLEs.

Lactational programming of glucose homeostasis: a window of opportunity

The window of lactation is a critical period during which nutritional and environmental exposures impact lifelong metabolic disease risk. Significant organ and tissue development, organ expansion and maturation of cellular functions occur during the lactation period, making this a vulnerable time during which transient insults can have lasting effects. This review will cover current literature on factors influencing lactational programming such as milk composition, maternal health status and environmental endocrine disruptors. The underlying mechanisms that have the potential to contribute to lactational programming of glucose homeostasis will also be addressed, as well as potential interventions to reduce offspring metabolic disease risk.

Postpartum Changes in Mood and Smoking-Related Symptomatology: An Ecological Momentary Assessment Investigation

Introduction

Postpartum smoking relapse is a highly prevalent public health problem. Mood and breast feeding are significantly associated with smoking relapse, although less is known about the temporality of these relationships. Therefore, this study utilized ecological momentary assessments (EMA) to prospectively examine changes in mood and smoking-related symptomatology in relationship to three events-childbirth, termination of breast feeding, and smoking relapse. We expected all three events to significantly alter mood and smoking-related symptomatology.

Methods

We enrolled a sample of pregnant women who had recently quit smoking and intended to remain quit during the postpartum. Participants were randomized to active/placebo progesterone to prevent postpartum relapse. Participants also completed daily EMA to collect data mood and smoking-related symptomatology as well as our three events of interest.

Results

Participants (n = 46) were, on average, 26.5 ± 0.8 years old and, prior to pregnancy, smoked 10.1 ± 0.7 cigarettes/day. We noted a number of significant within- and between-subject relationships. For example, participants reported a 24% decline in negative affect after childbirth (p = .0016). Among those who relapsed to smoking (n = 23), participants randomized to placebo had a significant increase in cigarette craving after relapse (β = 1.06, 95% confidence interval [CI] = 0.62 to 1.49, p value = .0003), whereas participants randomized to active progesterone did not (β = 0.63, 95% CI = -0.35 to 1.62, p value = .1824).

Conclusions

These observations suggest that mood and smoking-related symptomatology are influenced by childbirth, breast feeding, smoking relapse, and use of exogenous progesterone. Future research should explore how these observations may inform novel postpartum smoking relapse-prevention interventions.

Implications

Postpartum smoking relapse has been a persistent public health problem for more than 40 years. Although a number of significant predictors of postpartum smoking relapse have been identified (eg, depression and breast feeding), much of these analyses have relied on cross-sectional and/or self-reported retrospective data. Therefore, for the first time, we utilized ecological momentary assessment to explore the effect of childbirth, termination of breast feeding, and smoking relapse on mood and smoking-related symptomatology (eg, craving). Numerous significant relationships were observed, including a 96% increase in craving after smoking relapse. These novel observations can inform new and effective postpartum smoking relapse-prevention programs.

Evaluation of a federally funded mass media campaign and smoking cessation in pregnant women: a population-based study in three states

OBJECTIVES

In 2012, theCenters for Disease Control and Prevention initiated a national anti-smoking campaign, Tips from Former Smokers (Tips). As a result of the campaign, quit attempts among smokers increased in the general population by 3.7 percentage points. In the current study, we assessed the effects of Tips on smoking cessation in pregnant women.

METHODS

We used 2009-2013 certificates of live births in three US states: Indiana, Kentucky and Ohio. Smoking cessation by the third trimester of pregnancy was examined among women who smoked in the 3 months prepregnancy. Campaign exposure was defined as overlap between the airing of Tips 2012 (March 19-June 10) and the prepregnancy and pregnancy periods. Women who delivered before Tips 2012 were not exposed. Adjusted logistic regression was used to determine whether exposure to Tips was independently associated with smoking cessation.

RESULTS

Cessation rates were stable during 2009-2011 but increased at the time Tips 2012 aired and remained elevated. Overall, 32.9% of unexposed and 34.7% of exposed smokers quit by the third trimester (p<0.001). Exposure to Tips 2012 was associated with increased cessation (adjusted OR: 1.07, 95% CI 1.05 to 1.10).

CONCLUSIONS

Exposure to a national anti-smoking campaign for a general audience was associated with smoking cessation in pregnant women.

Postpartum Smoking Relapse and Breast Feeding: Defining the Window of Opportunity for Intervention

Background

Though many women spontaneously quit smoking during pregnancy, a large proportion relapse after delivery. Efforts aimed at reducing postpartum smoking relapse have been largely ineffective. Several studies have reported breast feeding as a primary factor influencing smoking abstinence duration. However, data on the potential role of breast feeding in smoking intervention efforts remain incomplete.

Methods

The Ulm SPATZ Health Study cohort consists of 1006 newborns of 970 mothers recruited in the University Medical Center Ulm, Germany. Kaplan-Meier plots, log-rank tests, and Cox proportional hazards models were used to assess differences in predominant and total breast-feeding duration stratified by smoking abstinence at 2 years and relapse period (by 6 weeks, 6 months, and 2 years postdelivery). Chi-square and Kruskal-Wallis tests were performed to identify significant differences in demographic and lifestyle factors across smoking categories.

Results

Approximately 70% of previous smokers who initiated breast feeding relapsed within 2 years. Relapse by 6 months was significantly associated with noninitiation of predominant breast feeding. Total breast-feeding duration rates among abstaining mothers and those who relapsed after 6 weeks mirrored those of nonsmokers respectively up to 1 year and 3 months. Lower age and education were mostly associated with smoking by 6 weeks. First parity and having a nonsmoking partner were associated with abstinence up to 2 years.

Conclusions

Interventions promoting breast feeding to incentivize continued smoking abstinence may be effective prior to weaning. Those promoting breast feeding longer than 6 months and partner smoking cessation may increase rates of long-term smoking abstinence lasting longer than 2 years postdelivery.

Implications

Most mothers who quit smoking during pregnancy relapse within 6 months of delivery. Though interventions targeting new mothers have been largely unsuccessful, relapse is often delayed until after weaning and targeted breast-feeding promotion has been suggested to enhance smoking cessation interventions. In this study, we assess the relationship between breast-feeding duration and long-term smoking abstinence by longitudinally investigating predominant and total breast-feeding patterns among mothers with a recent history of smoking stratified by period of relapse up to 2 years after delivery.

Tailoring a NICU-Based Tobacco Treatment Program for Mothers Who Are Dependent on Opioids

OBJECTIVE

To collect formative information to design a tailored tobacco treatment intervention for women with newborns treated or evaluated for neonatal abstinence syndrome and to explore current tobacco use behaviors and facilitators and barriers to smoking cessation.

DESIGN

Qualitative descriptive study.

SETTING

An academic medical center in the southern United States.

PARTICIPANTS

Mothers (N = 11) of newborns who were treated or evaluated for neonatal abstinence syndrome at birth within the preceding 3 months. Women recruited were older than 18 years and reported opioid dependence and smoking during pregnancy.

METHODS

Participants took part in semistructured individual interviews that lasted approximately 1 hour. Interviews were professionally transcribed and analyzed in MAXQDA using content analysis.

RESULTS

Five themes emerged from the data: Strategizing to Reduce Risk, Desire to Quit Smoking in the Future, Holding on to Smoking While Working Through Recovery, Feeling Judged by Nurses, and Feeling Supported and Empowered by Nurses. Participants reported that they to reduce risk to their newborns by avoiding second- and thirdhand smoke exposure. Participants wanted to stop smoking but reported many barriers, including multiple life stressors compounded by their newborns' extended stays in the hospital. However, most participants described overall positive experiences and the support of health care providers.

CONCLUSION

Holistic tobacco treatment programs that incorporate stress relief and social support and are led by trusted health care providers have the potential to be effective to reduce smoking in new mothers with histories of opioid dependence disorders and smoking and whose newborns are in the NICU.
