Cutting down: insights from qualitative studies of smoking in pregnancy

Using nicotine replacement therapy for smoking reduction in pregnancy: a qualitative study of pregnant women in the UK who smoke

OBJECTIVES

To explore the acceptability and perceived motivations and barriers of using nicotine replacement therapy (NRT) to reduce the number of daily cigarettes smoked in pregnancy, rather than for stopping completely.

DESIGN

Telephone, semi-structured interviews, audio-recorded and transcribed verbatim. Transcripts were analysed using an inductive thematic analysis.

PARTICIPANTS

Eighteen pregnant women in the UK, who were smoking or had recently stopped smoking, were recruited.

RESULTS

Half of interviewees reported having used NRT to reduce smoking during their current pregnancy, and there was overwhelming support for the UK National Health Service to recognise this as a potentially useful way to use these products. The cost and stigma associated with purchasing NRT products when pregnant were seen as barriers to using NRT in this way. The early offer of NRT for reduction along with a tailored, structured approach to support was seen as important.

CONCLUSIONS

Using NRT to help women, who are unable to stop smoking, to reduce their smoking may be acceptable to pregnant women. This study found women were already using NRT alongside ad hoc strategies to reduce their smoking. Further research evaluating structured smoking reduction support, alongside concurrent NRT use is needed.

Imperatives of health or happiness: Narrative constructions of long-term smoking after undergoing lung screening

Tobacco control policies reinforce a health imperative that positions citizens as duty-bound to manage their health by abstaining from or quitting smoking. Limited attention is paid to the repercussions - especially for lung screening - of anti-smoking rhetoric emphasising individual responsibility. Drawing on interviews with 27 long-term smokers involved in an international lung screening trial, this study analysed Australian smokers' narratives of smoking. By attending to stigma and the use of public health rhetoric within personal narratives, we show how narratives underscoring individual responsibility for quitting were layered with conflicting explanations of biological responsibility and normative expectations. Ironically, narratives of individual responsibility potentially undermine smoking cessation. In positioning smokers as responsible for their own healthy choices, such rhetoric also positions smokers as responsible for managing their emotional health, which some did through smoking. Thus, anti-smoking campaigns pit the neoliberal imperative of health against the happiness imperative. These findings have implications for the design and delivery of lung screening campaigns. They also support calls to move beyond health messaging emphasising individual choice, towards acknowledging the moral power of structures and public health campaigns to discipline citizens in unintended ways.

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.

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.

Phthalate levels in prenatal and postnatal bedroom dust in the SELMA study

Phthalates are common in polyvinyl chloride (PVC) plastics and numerous consumer goods in our homes from which they can migrate and adhere to indoor dust particles. It is known that indoor dust exposure contribute to human phthalate intake; however, there is a lack of large studies with a repeated-measure design investigating how phthalate levels in indoor dust may vary over time in people's homes. This study investigated levels of seven phthalates and one alternative plasticiser di-iso-nonyl-cyclohexane-di-carboxylate (DiNCH) in bedroom dust collected prenatally around week 25 during pregnancy and postnatally at six months after birth, from 496 Swedish homes. Prenatal and postnatal phthalate levels were compared using correlation and season-adjusted general linear regression models. Over the nine-month period, levels of six out of seven phthalates were associated as indicated by a positive Pearson correlation (0.18 < r < 0.50, P < .001) and Lin's concordance correlation between matched prenatal and postnatal dust samples. Compared to prenatal levels, the season-adjusted postnatal levels decreased for five phthalates, whilst di-ethyl-hexyl phthalate (DEHP), di-2-propylheptyl phthalate (DPHP) and DiNCH increased. The results suggest that families with higher phthalate levels in bedroom dust during pregnancy are likely to remain among those with higher levels in the infancy period. However, all average phthalate levels changed over this specific nine-month period suggesting that available phthalate sources or their use were altered between the dust collections. Changes in home characteristics, family lifestyle, and phthalate replacement trends may contribute to explain the differences.

Are empathic processes mechanisms of pregnancy's protective effect on smoking? Identification of a novel target for preventive intervention

BACKGROUND

Spontaneous cessation and reduction in smoking by pregnant women suggest that concern about others, or empathy, could be a malleable target for intervention. We examined various empathy-related processes in relations to reported and biochemically assessed smoking during pregnancy.

METHODS

Participants were 154 pregnant women (M = 12.4 weeks gestation, SD = 4.6) who were smoking cigarettes immediately prior to pregnancy recognition (85 had quit and 69 were still smoking at enrollment). Empathy-related processes were measured with performance-based paradigms (affect sharing, empathic concern, and theory of mind) and a speech sample (expressed emotion). Smoking was assessed with timeline follow back interviews and urine cotinine assays. Using zero-inflated Poisson regression models, we tested direct and interactive effects of empathy-related processes with respect to biologically verified smoking cessation (zero portion); and mean cigarettes/day smoked after pregnancy recognition among persistent smokers (count portion).

RESULTS

Affect sharing was inversely related to post-recognition cigarettes/day (B(SE) = -0.17(0.07), 95%C.I. -0.30,-0.04, p = .011) and moderated the relationship between pre-recognition smoking and post-recognition smoking consistent with a buffering effect (B(SE) = -.17(0.05); 95%C.I. - 0.28,-0.06; p = .002). Other empathy related processes showed neither direct nor interactive effects on smoking outcomes.

CONCLUSIONS

Further research is recommended to clarify the role of empathy in pregnancy smoking.

Impact of prenatal exposure characterization on early risk detection: Methodologic insights for the HEALthy Brain and Child Development (HBCD) study

BACKGROUND

A major challenge in prenatal drug exposure research concerns the balance of measurement quality with sample sizes necessary to address confounders. To inform the selection of optimal exposure measures for the HEALthy Brain and Child Development (HBCD) Study, we employed integrated analysis to determine how different methods used to characterize prenatal tobacco exposure influence the detection of exposure-related risk, as reflected in normal variations in birth weight.

METHODS

Participants were N = 2323 mother-infant dyads derived from 7 independent developmental cohorts harmonized on measures of exposure, outcome (birthweight), and covariates. We compared estimates of PTE-related effects on birthweight derived from linear regression models when PTE was categorized dichotomously based on any fetal exposure (30% exposed; 69% not exposed); versus categorically, based on common patterns of maternal smoking during pregnancy (never smoked 69%; quit smoking 16%; smoked intermittently 2%; smoked persistently 13%). We secondarily explored sex differences in PTE-birthweight associations across these categorization methods.

RESULTS

When PTE was categorized dichotomously, exposure was associated with a - 125-g difference in birthweight (95% C.I. -173.7 - -76.6, p < .0001). When PTE was characterized categorically based on maternal smoking patterns, however, exposure was associated with either no difference in birthweight if mothers quit smoking by the end of the first trimester (B = -30.6, 95% C.I. -88.7-27.4, p = .30); or a - 221.8 g difference in birthweight if mothers did not [95% C.I. (-161.7 to -282.0); p < .001]. Qualitative sex differences were also detected though PTE x sex interactions did not reach statistical significance. Maternal smoking cessation during pregnancy was associated with a 239.3 g increase in birthweight for male infants, and a 114.0 g increase in birthweight for females infants (p = .07).

CONCLUSIONS

Categorization of PTE based on patterns of maternal smoking rather than the presence or absence of exposure alone revealed striking nuances in estimates of exposure-related risk. The described method that captures both between-individual and within-individual variability in prenatal drug exposure is optimal and recommended for future developmental investigations such as the HBCD Study.

Indigenous Women's Experiences of Smoking and Quitting Smoking in Pregnancy: A Phenomenological Study

BACKGROUND

Maternal smoking during pregnancy (MSDP) is an important public health concern because of potential adverse health effects to the woman, fetus, and child after birth. Prevalence rates are high among groups with socioeconomic disadvantage, including Indigenous women.

PURPOSE

This study was conducted to understand experiences of MSDP for Indigenous women.

METHODS

The study was conducted using phenomenology. Data were collected through interviews with 15 pregnant and postnatal Indigenous women who had smoked during pregnancy. The data were analyzed for themes using phenomenological methods.

RESULTS

The women's narratives revealed four experiences: quitting smoking during pregnancy to protect the unborn baby from harm; quitting smoking during pregnancy because of personal adverse health effects; cutting down smoking during pregnancy and feeling remorse for not quitting; and keeping on smoking during pregnancy and not planning to try to quit. The women's experiences also indicated several impediments to quitting smoking.

CONCLUSIONS

There is need for health care policy to ensure adequate smoking cessation services and support for Indigenous women who smoke in pregnancy. Health care professionals should provide individualized interventions that take into account the challenges to quitting that pregnant women experience and that are in accordance with clinical practice guidelines for MSDP.

Household food insecurity and in-utero and early life smoke exposure: Data from NHANES 2003-2016

In-utero, postnatal, and childhood smoke exposure are associated with adverse health consequences, and examining factors related to smoke exposure during these vulnerable periods are critical to inform efforts that promote maternal and child health. This study included pregnant and postpartum women aged 20-44 years and children aged 3-12 years from National Health and Nutrition and Examination Survey (NHANES) 2003-2016 cycles. Logistic regression examined association of household food insecurity with firsthand (FHS) and secondhand (SHS) exposure among pregnant and postpartum women, and SHS exposure among children, based on serum cotinine and respondent-reports. Very low household food security was significantly associated with increased odds of cotinine-based FHS exposure among pregnant (OR(95%CI) = 5.19 (1.75, 15.39)) and postpartum women (OR(95%CI) = 4.75(1.66, 13.57)). Non-smoking, postpartum women from very low food secure households also had significantly greater odds of cotinine-based SHS exposure (OR(95%CI) = 7.40 (2.08, 26.37)) than those from food secure households. Using respondent-reported smoking status, low food security in pregnant and postpartum women was significantly related to increased odds of FHS exposure (OR(95% CI) = 3.75(1.52, 9.23)). Further, children from marginal, low and very low food secure households had significantly higher odds of SHS exposure compared to those from food secure households. Results imply the co-occurrence food insecurity and in-utero and early life smoke exposure.

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.

Perceived safety of smoking a few cigarettes during pregnancy and provider advice in a sample of pregnant smokers from Romania

AIMS

To assess the prevalence of the perceived safety of smoking a few (generally fewer than five per day) cigarettes during pregnancy and identify associated factors in a sample of pregnant smokers in Romania, a middle-income country.

DESIGN AND SETTING

Cross-sectional design with a convenience sample using a polled data set collected between 2016 and 2019 in the formative and baseline phases of the Quit Together randomized control trial (RCT) in Romania. Data were collected using a structured questionnaire administered by research assistants in clinics in the formative phase and self-administered through the study website at the RCT baseline.

PARTICIPANTS

A total of 217 pregnant smokers (mean age = 28.5 ± 5.8) enrolled in the formative and RCT phases of the research project.

MEASUREMENTS

The main outcome was the perceived safety of smoking a few cigarettes during pregnancy (generally fewer than five per day). Covariates included the health-care providers' advice towards smoking tobacco cigarettes during pregnancy, socio-demographics, the presence of depression and anxiety symptoms and level of nicotine dependence.

FINDINGS

More than 35% of participants agreed that smoking a few cigarettes during pregnancy was safe for them and their baby. The perceived safety of smoking a few cigarettes during pregnancy was significantly associated with being told by health-care providers that it is acceptable to continue to smoke cigarettes in small amounts [odds ratio (OR) = 3.08; 95% CI = 1.35-6.99; P < 0.01], perceived harm reduction of smoking light cigarettes (OR = 2.67; 95% CI = 1.19-5.97; P = 0.02) and moderate to severe depression and anxiety score (OR = 0.34; 95% CI = 0.13-0.84; P = 0.02).

CONCLUSIONS

More than one-third of pregnant Romanian women appear to believe that smoking 'a few' cigarettes during pregnancy is safe for them and their fetuses. Those who are told by their health-care providers that it is acceptable to smoke in small amounts during pregnancy have higher odds of perceiving smoking 'a few' cigarettes during pregnancy as safe compared with other pregnant Romanian women.

Experts' Views on Behaviour Change Techniques for Smoking Cessation in Pregnancy: A Qualitative Study

Smoking during pregnancy is a global health problem which has devastating health implications. Behavioural support is an important part of smoking cessation support for pregnant women. Research has identified barriers and facilitators (B&Fs) and effective behaviour change techniques (BCTs) to aid women's quit attempts. However, the extent to which and how these BCTs are used in practice is unclear. The research aimed to establish experts' views on how behavioural support can be optimised and techniques operationalised in clinical practice, by identifying ways to address known B&Fs for smoking cessation in pregnancy. A focus group discussion took place with six experts, which highlighted how BCTs can be used in practice to support women in their quit attempts. A thematic analysis was conducted to elicit overarching themes. Five themes were found: involving the family, empowering women, using incentives to boost motivation, using practical techniques to help women with their quit attempts and managing expectations about nicotine replacement therapy. Empowering women to make their own decisions and encouraging small positive changes in smoking habits, using visual aids (e.g., growth charts) to inform women of the harms of smoking to the baby and treating families holistically were deemed important.

Exposure to Tobacco, Environmental Tobacco Smoke and Nicotine in Pregnancy: A Pragmatic Overview of Reviews of Maternal and Child Outcomes, Effectiveness of Interventions and Barriers and Facilitators to Quitting

The aim of this review of reviews was to collate the latest evidence from systematic reviews about the maternal and child health outcomes of being exposed to tobacco and nicotine during pregnancy; the effectiveness of interventions designed to reduce these exposures, and barriers to and facilitators of smoking cessation during pregnancy. Two databases were searched to obtain systematic reviews published from 2010 to 2019. Pertinent data from 76 articles were summarized using a narrative synthesis (PROSPERO reference: CRD42018085896). Exposure to smoke or tobacco in other forms during pregnancy is associated with an increased risk of obstetric complications and adverse health outcomes for children exposed in-utero. Counselling interventions are modestly effective, while incentive-based interventions appear to substantially increase smoking cessation. Nicotine replacement therapy is effective during pregnancy but the evidence is not conclusive. Predictors and barriers to smoking cessation in pregnancy are also discussed. Smoking during pregnancy poses substantial risk to mother's and child's health. Psychosocial interventions and nicotine replacement therapy (NRT) appear to be effective in helping pregnant women quit smoking. Barriers to smoking cessation must be identified and steps taken to eradicate them in order to reduce smoking among pregnant women. More research is needed on smoking cessation medications and e-cigarettes.

Understanding pregnant women's readiness to engage in risk-reducing measures to prevent infections during pregnancy

The aim of this study was to develop a conceptual understanding of women's readiness to engage in behaviours to reduce the risk of acquiring infections during pregnancy, using cytomegalovirus, the most common congenital infection as a case. Thirty-three pregnant women participated in semi-structured interviews. The findings illustrate that for behavioural change to become viable, it is necessary for individuals to consider barriers or facilitators at the individual, inter-personal and system levels. By widening the theoretical lens beyond individual cognitive determinants, the model places sufficient emphasis on factors, such as collective identity, support networks, interaction with the healthcare system and wider community, relevant to pregnant women.

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.

Barriers experienced by nurses providing smoking cessation support to disadvantaged, young women during and after pregnancy

In Europe, smoking during and after pregnancy is still highly prevalent among socioeconomically disadvantaged women. Nurses caring for these women can play a key role in smoking cessation, but encounter many problems when providing support. This research aims to identify barriers in providing smoking cessation support, experienced by nurses working within a Dutch preventive care programme for disadvantaged young women (VoorZorg), and to understand the underlying reasons of these barriers. Sixteen semi-structured interviews with nurses were performed. All interviews were recorded, transcribed and analysed deductively and inductively. We found that the VoorZorg programme provided nurses with training, resources and time to deliver smoking cessation support. Yet, nurses experienced important barriers, such as unmotivated clients and support methods that do not fit clients' needs. Underlying reasons are competing care demands, unsatisfactory training for cessation support, lack of self-efficacy in attending their clients, and conflicts with own professional attitudes. The results emphasise that nurses' ability to provide smoking cessation support could be improved by proper training in interventions that fit their clients' needs, and by time schedules and task definitions that help them to prioritise smoking cessation support over other matters.

What components of smoking cessation care during pregnancy are implemented by health providers? A systematic review and meta-analysis

BACKGROUND

Pregnancy is an opportunity for health providers to support women to stop smoking.

OBJECTIVES

Identify the pooled prevalence for health providers in providing components of smoking cessation care to women who smoke during pregnancy.

DESIGN

A systematic review synthesising original articles that reported on (1) prevalence of health providers' performing the 5As ('Ask', 'Advise', 'Assess', 'Assist', 'Arrange'), prescribing nicotine replacement therapy (NRT) and (2) factors associated with smoking cessation care.

DATA SOURCES

MEDLINE, EMBASE, CINAHL and PsycINFO databases searched using 'smoking', 'pregnancy' and 'health provider practices'.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Studies included any design except interventions (self-report, audit, observed consultations and women's reports), in English, with no date restriction, up to June 2017.

PARTICIPANTS

Health providers of any profession.

DATA EXTRACTION, APPRAISAL AND ANALYSIS

Data were extracted, then appraised with the Hawker tool. Meta-analyses pooled percentages for performing each of the 5As and prescribing NRT, using, for example, 'often/always' and 'always/all'. Meta-regressions were performed of 5As for 'often/always'.

RESULTS

Of 3933 papers, 54 were included (n=29 225 participants): 33 for meta-analysis. Health providers included general practitioners, obstetricians, midwives and others from 10 countries. Pooled percentages of studies reporting practices 'often/always' were: 'Ask' (n=9) 91.6% (95% CI 88.2% to 95%); 'Advise' (n=7) 90% (95% CI 72.5% to 99.3%), 'Assess' (n=3) 79.2% (95% CI 76.5% to 81.8%), 'Assist (cessation support)' (n=5) 59.1% (95% CI 56% to 62.2%), 'Arrange (referral)' (n=6) 33.3% (95% CI 20.4% to 46.2%) and 'prescribing NRT' (n=6) 25.4% (95% CI 12.8% to 38%). Heterogeneity (I2) was 95.9%-99.1%. Meta-regressions for 'Arrange' were significant for year (p=0.013) and country (p=0.037).

CONCLUSIONS

Health providers 'Ask', 'Advise' and 'Assess' most pregnant women about smoking. 'Assist', 'Arrange' and 'prescribing NRT' are reported at lower rates: strategies to improve these should be considered.

Prevalence and predictors of maternal smoking prior to and during pregnancy in a regional Danish population: a cross-sectional study

BACKGROUND

Maternal smoking is still a major public health problem posing the risk of several negative health outcomes for both the pregnant woman and her offspring. The prevalence of maternal smoking in Denmark and other high-income countries has decreased continuously since the 1980s, and a prevalence below 10% of women who continue to smoke during pregnancy has been reported in studies after 2010. Previous studies have shown that low socioeconomic status is associated with maternal smoking. Information from the Danish Birth Register about maternal smoking shows that the prevalence of women who report to smoke in pregnancy has decreased continuously with 23.3% who reported ever smoking in pregnancy in 2000, 12.9% in 2010 and 9.0% in 2017. The aim of this study was to estimate the prevalence of maternal smoking at the time of conception and at 20 weeks of gestation in a regional Danish population, to describe differences in maternal characteristics among smokers, quitters and never-smokers, and to estimate predictors of smoking at the time of conception.

METHODS

A cross-sectional study was conducted among pregnant women receiving antenatal care at the Department of Obstetrics, Zealand University Hospital, Denmark from August 2015 to March 2016 (n = 566). The main outcome was smoking at the time of conception and at 20 weeks of gestation. The questionnaire also collected information about maternal, health-related and sociodemographic characteristics. Descriptive analysis was conducted, and multivariate logistic regression analysis was used to assess the potential associated predictors (adjusted odds ratio).

RESULTS

The prevalence of self-reported smoking at the time of conception was 16% (n = 90) and 6% smoked at 20 weeks of gestation (n = 35), as 61% of smokers quit smoking during early pregnancy. Multiple logistic regression analysis showed that significant predictors for smoking at conception were the socioeconomic factors; ≤12 years of education, shift work and being unemployed.

CONCLUSION

The prevalence of self-reported maternal smoking in this regional Danish population of pregnant women is lower than seen in previous studies. However, predictors for smoking at the time of conception remain to be factors of low socioeconomic status confirming a social inequality in maternal smoking. Women at risk of smoking during pregnancy must be identified in early pregnancy or even before pregnancy and be offered interventions to help them quit smoking.

Smoking during pregnancy, stigma and secrets: Visual methods exploration in the UK

BACKGROUND

Moral judgements are commonly directed towards mothers through reference to health behaviour in pregnancy, and working-class mothers are particularly subject to this moral gaze.

AIM

To gain an in-depth understanding of the health issues affecting 10 low income pregnant women from deprived areas of south Wales, UK.

METHODS

Participants completed visual activities (timelines, collaging or thought bubbles and dyad sandboxing) prior to each interview. Participants' visual representations were used in place of a topic guide, to direct the interview. Guided by feminist principles, 28 interviews were completed with 10 women. Data were analysed thematically.

FINDINGS

Smoking was discussed at length during interviews, and this paper focuses on this issue alone. Five of the participants had smoked during pregnancy. Negative reactions were directed towards pregnant women who smoked in public, resulting in maternal smoking being undertaken in private. Participants also reported awkward relationships with midwives and other health professionals, including receipt of public health advice in a judgemental tone.

DISCUSSION

Smoking during pregnancy is a particularly demonised and stigmatised activity. This stigma is not always related to the level of risk to the foetus, and instead can be seen as a moral judgement about women. We urgently need to move from individualised neo-liberal discourses about the failure of individual smokers, to a more socio-ecological view which avoids victim blaming.

CONCLUSION

Stigma from friends, family, strangers and health professionals may lead to hidden smoking. This is a barrier to women obtaining evidence based stop smoking support.

Tailored Intervention for Smoking Reduction and Cessation for Young and Socially Disadvantaged Women During Pregnancy

Rates of smoking during pregnancy remain high in Canada, and cessation rates are low among women who are younger than 24 years and who are socially disadvantaged, that is, have few social and economic resources because of poverty, violence, or mental health issues. On the basis of findings from literature reviews and consultation with policy makers, we developed and operationalized four approaches that can be used by health care providers to tailor interventions for tobacco use in pregnancy. These four approaches are woman centered, trauma informed, harm reducing, and equitable. Public health initiatives that address smoking in young and socially disadvantaged women could be more sharply focused by shifting to such tailored approaches that are grounded in social justice aims, span pre- and postpregnancy periods, and can be used to address women's social contexts and concerns.

Comparing Smoking Topography and Subjective Measures of Usual Brand Cigarettes Between Pregnant and Non-Pregnant Smokers

Introduction

Most pregnant smokers report abruptly reducing their cigarettes per day (CPD) by ~50% after learning of pregnancy and making further smaller reductions over the remainder of their pregnancy. Laboratory and naturalistic studies with non-pregnant smokers have found that these types of reductions often lead to changes in smoking topography (i.e., changes in smoking intensity to maintain a desired blood-nicotine level). If pregnant women smoke more intensely, they may expose themselves and their offspring to similar levels of toxicants despite reporting reductions in CPD.

Methods

Pregnant and non-pregnant female smokers (n = 20 and 89, respectively) participated. At the experimental session, after biochemical confirmation of acute abstinence, participants smoked one usual brand cigarette ad lib through a Borgwaldt CReSS Desktop Smoking Topography device. Carbon monoxide (CO) and measures of nicotine withdrawal, craving, and reinforcement derived from smoking were also collected.

Results

The two groups did not differ on demographic or smoking characteristics at screening, except nicotine metabolism rate, which as expected, was faster in pregnant smokers. Analyses suggest that none of the smoking topography parameters differed between pregnant and non-pregnant smokers, although pregnant smokers had a significantly smaller CO boost. Both groups reported similar levels of relief of withdrawal and craving after smoking, but other subjective effects suggest that pregnant smokers find smoking less reinforcing than non-pregnant smokers.

Conclusions

Pregnant smokers do not smoke cigarettes differently than non-pregnant women, but appear to find smoking comparatively less pleasurable.

Implications

This is the first study to assess smoking topography in pregnant women. Pregnant women appear to be at increased risk for smoking cigarettes with more intensity because of (1) their tendency to make significant abrupt reductions in the number of cigarettes they smoke each day after learning of pregnancy and (2) an increase in nicotine metabolism induced by pregnancy. Despite these changes, the present results suggest that pregnant women do not smoke cigarettes more intensely or in a way that causes more toxicant exposure, perhaps due to a reportedly less pleasurable smoking experience.

Smoking and quitting smoking during pregnancy: A qualitative exploration of the socio-cultural context for the development of a couple-based smoking cessation intervention in Romania

INTRODUCTION

Smoking during pregnancy has negative effects on the mother and the unborn infant. Barriers to and facilitators of smoking cessation during pregnancy are context-dependent and multifaceted. This qualitative research explored pregnant women's experiences with smoking and cessation in Romania, and informed the development of a couple-focused smoking cessation intervention.

METHODS

Semi-structured, in-depth interviews were conducted via telephone, with 15 pregnant women who smoked during pregnancy or had quit smoking upon learning about the pregnancy or shortly before. A hybrid inductive-deductive approach to thematic analysis was used, to identify patterns in the data and explore women's narratives, in relation to smoking and smoking cessation.

RESULTS

Three main themes emerged from the data, which shaped the socio-cultural adaptation of the intervention to the local context: 1) Access to and mixed messages from the healthcare system that describe an inconsistent discourse from the healthcare system regarding smoking during pregnancy with some physicians not emphasizing the need for cessation, 2) Cessation as individual or team effort with variations in partner dynamics and difficulty in quitting that have important roles in perceptions about team efforts, and 3) Transition to motherhood and motivation to quit for the health of the pregnancy and infant, although in isolated cases women felt less connected with the pregnancy and such motivators.

CONCLUSIONS

Pregnant women in Romania face systemic, interpersonal, and individual-level barriers that can be responsively integrated in smoking cessation interventions, by culturally adapting them to the local context.

Smoking and quit attempts during pregnancy and postpartum: a longitudinal UK cohort

OBJECTIVES

Pregnancy motivates women to try stopping smoking, but little is known about timing of their quit attempts and how quitting intentions change during pregnancy and postpartum. Using longitudinal data, this study aimed to document women's smoking and quitting behaviour throughout pregnancy and after delivery.

DESIGN

Longitudinal cohort survey with questionnaires at baseline (8-26 weeks' gestation), late pregnancy (34-36 weeks) and 3 months after delivery.

SETTING

Two maternity hospitals in one National Health Service hospital trust, Nottingham, England.

PARTICIPANTS

850 pregnant women, aged 16 years or over, who were current smokers or had smoked in the 3 months before pregnancy, were recruited between August 2011 and August 2012.

OUTCOME MEASURES

Self-reported smoking behaviour, quit attempts and quitting intentions.

RESULTS

Smoking rates, adjusting for non-response at follow-up, were 57.4% (95% CI 54.1 to 60.7) at baseline, 59.1% (95% CI 54.9 to 63.4) in late pregnancy and 67.1% (95% CI 62.7 to 71.5) 3 months postpartum. At baseline, 272 of 488 current smokers had tried to quit since becoming pregnant (55.7%, 95% CI 51.3 to 60.1); 51.3% (95% CI 44.7 to 58.0) tried quitting between baseline and late pregnancy and 27.4% (95% CI 21.7 to 33.2) after childbirth. The percentage who intended to quit within the next month fell as pregnancy progressed, from 40.4% (95% CI 36.1 to 44.8) at baseline to 29.7% (95% CI 23.8 to 35.6) in late pregnancy and 14.2% (95% CI 10.0 to 18.3) postpartum. Postpartum relapse was lower among women who quit in the 3 months before pregnancy (17.8%, 95% CI 6.1 to 29.4) than those who stopped between baseline and late pregnancy (42.9%, 95% CI 24.6 to 61.3).

CONCLUSIONS

Many pregnant smokers make quit attempts throughout pregnancy and postpartum, but intention to quit decreases over time; there is no evidence that smoking rates fall during gestation.

Specification of Change Mechanisms in Pregnant Smokers for Malleable Target Identification: A Novel Approach to a Tenacious Public Health Problem

Maternal smoking during pregnancy (MSDP) continues to be a leading modifiable risk factor for perinatal complications and a range of neurodevelopmental and cardio-metabolic outcomes across the lifespan. Despite 40 years of intervention research less than one in five pregnant smokers who receive an intervention quit by delivery. Within this context, recognition of pregnancy is commonly associated with abrupt suspension or reduction of smoking in the absence of intervention, yet has not been investigated as a volitional target. The goal of this article is to provide the empirical foundation for a novel direction of research aimed at identifying malleable targets for intervention through the specification of behavior change mechanisms specific to pregnant women. To do so, we: (1) summarize progress on MSDP in the United States generated from conventional empirical approaches to health behavior change; (2) discuss the phenomenon of spontaneous change in the absence of intervention among pregnant smokers to illustrate the need for mechanistic specification of behavior change motivated by concern for fetal well-being; (3) summarize component processes in neurobiological models of parental and non-parental social behaviors as a conceptual framework for understanding change mechanisms during pregnancy; (4) discuss the evidence for the malleability of these processes to support their translational relevance for preventive interventions; and (5) propose a roadmap for validating the proposed change mechanism using an experimental medicine approach. A greater understanding of social and interpersonal processes that facilitate health behavior change among expectant mothers and how these processes differ interindividually could yield novel volitional targets for prenatal interventions. More broadly, explicating other-oriented mechanisms of behavior change during pregnancy could serve as a paradigm for understanding how social and interpersonal processes positively influence health behaviors across the lifespan.

e-Cigarette Use and Perceived Harm Among Women of Childbearing Age Who Reported Tobacco Use During the Past Year

BACKGROUND

The prevalence of electronic cigarette use grows. Amid increased e-cigarette use nationwide, this paper attempts to identify underlying risk factors for the most vulnerable populations.

OBJECTIVE

The purpose of the study was to assess predictors of e-cigarette use among female current and former tobacco users of childbearing age-specifically to determine whether demographic factors, pregnancy status, conventional cigarette smoking, and perceived e-cigarette harm are associated with e-cigarette use. Reasons for using e-cigarettes were also measured.

METHODS

A cross-sectional, correlational design was used; 194 current and former female tobacco users, 18-45 years of age, from two university-affiliated prenatal clinics and one women's health clinic in Kentucky took part. Slightly more than half were pregnant. Age, race/ethnicity, education, pregnancy status, use history for cigarettes and e-cigarettes, and perception of health hazard from e-cigarettes were measured, and associations with e-cigarette use were made with Mann-Whitney U-tests or Spearman's rank correlations. Predictors of e-cigarette use were determined using proportional odds modeling.

RESULTS

Most current e-cigarette users were also current cigarette smokers (88%). Nearly half of current and former e-cigarette users were pregnant. Most women perceived e-cigarettes as a minor (38%) or moderate (31%) health hazard. In the proportional odds model, younger women were at greater risk for e-cigarette use, whereas minority women and those who were pregnant were less likely to be e-cigarette users.

DISCUSSION

Pregnant women were less likely to be more recent e-cigarette users, compared with nonpregnant women. However, nearly all current e-cigarette users were dual tobacco users, including pregnant women. It is both imperative and timely to determine the impact of e-cigarette use on maternal and infant health, thus improving healthcare provider confidence to discuss the health implications of e-cigarette use with their patients.

The Gendered Experience of Smoking Stigma: Implications for Tobacco Control

Tobacco denormalization is a widely accepted tobacco control strategy, shaping policies and programs throughout the United States as well as globally. In spite of widespread beliefs about the effectiveness of tobacco denormalization approaches, concerns about their emphasis on stigmatization have emerged. Social science research on smoking stigma raises questions about the potential iatrogenic consequences of tobacco denormalization approaches. Few studies have considered how smoking stigma may be internalized differently by different people, particularly those who experience stigmatization because of other socially-ascribed makers of inequity (e.g. race, ethnicity, gender, sexuality). The intersection of multiple stigmas may work to intensify the "social isolation and marginalization" that some people already experience (Greaves & Hemsing 2009; pg S127). This paper presents results from a pattern-level analysis of focus group and interview data from a study investigating smoking-related stigma and perceptions of tobacco denormalization approaches among 15 low income Black women who smoke in the San Francisco Bay Area. Our analysis revealed a cycle where Black women's experiences with structural oppression resulted in stress and the use of cigarettes to cope with that stress. Though the connection between smoking and stress is well documented in previous research, our analysis further revealed the additional contribution of the stigmatization of smoking and how it intensifies inequity for Black women who smoke. Implications of these findings for tobacco control and prevention are discussed.

Getting over the shock: taking action on Indigenous maternal smoking

Smoking rates are slow to decline among pregnant Indigenous women. One in two pregnant Indigenous Australian women is a tobacco smoker compared with one in eight in the non-Indigenous population. The National Close the Gap strategy ambitiously aims to reduce Indigenous smoking prevalence to half by 2018, but this goal is unlikely to be achieved. Evidence is growing to better inform targeted strategies for Indigenous pregnant women based on national and international studies. It is proposed to be an appropriate time to refine translational approaches for anti-tobacco messages and cessation support in this population, rather than waiting for further empirical research before making these essential changes. Systemic barriers to Indigenous pregnant women receiving equitable primary health care have been identified, are remediable, and urgently require addressing. These barriers include: (1) lack of subsidised access to suitable oral forms of nicotine replacement therapy; (2) lack of clinician training in the complex area of management of maternal Indigenous smoking; and (3) lack of targeted health promotion programs addressing the psychosocial challenges that Indigenous women face. In the interim, translational strategies to target tobacco control and cessation in pregnant Indigenous women need to be based on current evidence.

Perceptions of Electronic Cigarettes Among Medicaid-Eligible Pregnant and Postpartum Women

OBJECTIVE

To describe perceptions and beliefs about electronic cigarette (e-cigarette) use during pregnancy among pregnant and newly postpartum women.

DESIGN

An exploratory, qualitative descriptive study.

SETTING

University-affiliated prenatal clinics.

PARTICIPANTS

Twelve pregnant or recently postpartum women who reported use of tobacco and electronic cigarettes.

METHODS

Semistructured focus groups were audio recorded and professionally transcribed. The transcripts were coded to consensus and analyzed with MAXQDA software (version 11) using content analysis.

RESULTS

Four overarching themes emerged: (a) Attraction to E-Cigarettes as a Harm Reduction Strategy, (b) Uncertainty Regarding the Health Effects of E-Cigarettes; (c) Ambivalence Regarding Novel Product Characteristics; and (d) Behaviors Reflected Dual Use and Often Complete Relapse to Traditional Cigarettes.

CONCLUSION

Pregnant women are initially attracted to e-cigarettes as a harm reduction strategy, but they often return to traditional cigarettes in the postpartum period. Nurses should counsel pregnant women on the adverse effects of fetal exposure to nicotine. Evidence-based nursing interventions are needed to prevent relapse during the postpartum period.

Understanding Pregnant Smokers' Adherence to Nicotine Replacement Therapy During a Quit Attempt: A Qualitative Study

BACKGROUND

Pregnant smokers may be offered nicotine replacement therapy (NRT) alongside behavioral support to assist with a quit attempt. Yet trials of NRT have found adherence to be low among pregnant women, and this has made it difficult to determine the efficacy of NRT. The aim of this study is to understand the experience of pregnant women who use NRT but discontinue this early or do not use the medication as recommended.

METHODS

Semi-structured telephone interviews were conducted with 14 pregnant smokers who had recently been prescribed NRT, but self-reported poor NRT adherence or discontinuing treatment prematurely. Data were transcribed and analyzed using inductive thematic analysis

RESULTS

There were four main themes identified; expectations of NRT, experience of using NRT, safety concerns and experience of using e-cigarettes. Some women intentionally used NRT to substitute a proportion of their cigarette intake and smoked alongside. Most women smoked while using NRT. Women who underutilized NRT did so as they experienced side effects, or were concerned that using NRT instead of smoking could actually increase their nicotine exposure and potential for increased nicotine dependence or fetal harm. Most women spoke about the use of e-cigarettes as a smoking cessation method but only a few had actually experienced using them during pregnancy.

CONCLUSION

Many women underused NRT but simultaneously smoked. Challenging negative perceptions about NRT and educating women further about the risks of smoking may encourage them to use NRT products as recommended.

IMPLICATIONS

These findings add to the research surrounding the efficacy of NRT during pregnancy by providing insight into how pregnant women use NRT during a quit attempt and how this may influence adherence. It may assist health professionals to support pregnant smokers by increasing their understanding about the differing ways in which women use NRT and help them address concerns women may have about the safety of NRT.
