Understanding the potential of teachable moments: the case of smoking cessation

The effectiveness of smoking cessation, alcohol reduction, diet and physical activity interventions in changing behaviours during pregnancy: A systematic review of systematic reviews

BACKGROUND

Pregnancy is a teachable moment for behaviour change. Multiple guidelines target pregnant women for behavioural intervention. This systematic review of systematic reviews reports the effectiveness of interventions delivered during pregnancy on changing women's behaviour across multiple behavioural domains.

METHODS

Fourteen databases were searched for systematic reviews published from 2008, reporting interventions delivered during pregnancy targeting smoking, alcohol, diet or physical activity as outcomes. Data on behaviour change related to these behaviours are reported here. Quality was assessed using the JBI critical appraisal tool for umbrella reviews. Consistency in intervention effectiveness and gaps in the evidence-base are described.

RESULTS

Searches identified 24,388 results; 109 were systematic reviews of behaviour change interventions delivered in pregnancy, and 36 reported behavioural outcomes. All smoking and alcohol reviews identified reported maternal behaviours as outcomes (n = 16 and 4 respectively), whereas only 16 out of 89 diet and/or physical activity reviews reported these behaviours. Most reviews were high quality (67%) and interventions were predominantly set in high-income countries. Overall, there was consistent evidence for improving healthy diet behaviours related to increasing fruit and vegetable consumption and decreasing carbohydrate intake, and fairly consistent evidence for increase in some measures of physical activity (METs and VO2 max) and for reductions in fat intake and smoking during pregnancy. There was a lack of consistent evidence across reviews reporting energy, protein, fibre, or micronutrient intakes; smoking cessation, abstinence or relapse; any alcohol behaviours.

CONCLUSIONS

The most consistent review evidence is for interventions improving dietary behaviours during pregnancy compared with other behaviours, although the majority of diet reviews prioritised reporting health-related outcomes over behavioural outcomes. Heterogeneity between reported behaviour outcomes limits ability to pool data in meta-analysis and more consistent reporting is needed. Limited data are available for alcohol interventions in pregnancy or interventions in low- or middle-income-countries, which are priority areas for future research.

Intensity- and domain-specific physical activity levels between cancer survivors and non-cancer diagnosis individuals: a propensity score matching analysis

PURPOSE

To examine intensity- and domain-specific physical activity (PA) levels between Korean cancer survivors compared with non-cancer individuals.

METHODS

We used data from the 2014-2016 Korean National Health and Nutrition Examination Survey (KNHNES) to compare PA levels between 639 cancer survivors and 15,352 non-cancer individuals. Using the 1:5 propensity score matching analysis by sex, age, body mass index (BMI), and education level, 3195 non-cancer individuals were selected. Global Physical Activity Questionnaire (GPAQ) was used to assess PA levels.

RESULTS

Cancer survivors were more likely to participate in a leisure-time PA (64.5 ± 157.9 vs. 51.8 ± 145.3 min/week, p < 0.002) compared with non-cancer individuals, while no difference was observed between groups in work and transportation. Cancer survivors undergoing treatment participated in more leisure-time PA (80.9 ± 169.2 vs. 56.6 ± 151.8 min/week, p < 0.02) compared with cancer survivors who completed cancer treatment. However, we found no significant difference in vigorous-intensity PA (18.8 ± 113.9 vs. 20.5 ± 156.1 min/week, p = 0.56) and moderate-intensity PA (186.2 ± 313.1 vs. 203.1 ± 355.3 min/week, p = 0.17) levels between cancer survivors and non-cancer individuals.

CONCLUSIONS

This study showed that cancer survivors were more participated in leisure-time PA compared with age, gender, BMI, and education levels matched non-cancer individuals.

Postpartum lifestyle interventions among women with pre-eclampsia: a scoping review protocol

INTRODUCTION

Compared to women with normotensive pregnancies, women with a history of pre-eclampsia have a roughly fourfold increased risk of developing chronic arterial hypertension and a twofold increased risk of developing cardiovascular disease (CVD). Lifestyle changes, such as increased physical activity, weight loss, smoking cessation and healthy diet, are effective for CVD prevention in the general population. However, no scoping review or systematic review of postpartum lifestyle interventions among women with pre-eclampsia have, to our best knowledge, been performed. The objective of this scoping review is to provide an overview of the available research literature on postpartum lifestyle interventions to reduce the risk of CVD among women with pre-eclampsia.

METHODS AND ANALYSIS

The protocol is based on the framework outlined by Arksey and O'Malley. Databases to be searched include: PubMed, Embase CINAHL and the JBI Database of Systematic Reviews and Implementation Reports. The search will be performed after the publication of this protocol (estimated to be 1 June 2020) and will be repeated 1 month prior to the submission for publication of the final review (estimated to be 1 January 2021). The review will consider studies that include women in the postpartum period (in particular, but not restricted to, the first 12 months after delivery), with a history of pre-eclampsia. Data will be extracted by two independent reviewers using a data extraction tool including specific details about the population, concept, context, study methods and key findings relevant to the review objective. Any disagreements between the reviewers will be resolved through discussion, or with a third reviewer. The extracted data will be presented in diagrammatic or tabular form that align with the objective of this scoping review. A narrative summary will accompany the tabulated and/or charted results and will describe how the results relate to the reviews objective and questions.

ETHICS AND DISSEMINATION

Since all data will be obtained from publicly available materials, the proposed scoping review does not require ethical approval. The results will be submitted for publication in an open-access peer-reviewed journal and presented at relevant conferences.

Effectiveness of an Opt-Out Electronic Heath Record-Based Tobacco Treatment Consult Service at an Urban Safety Net Hospital

BACKGROUND

To address the burden of tobacco use in underserved populations, our safety net hospital developed a tobacco treatment intervention consisting of an "opt-out" electronic health record-based best practice alert + order set, which triggers consultation to an inpatient tobacco treatment consult (TTC) service for all hospitalized smokers.

RESEARCH QUESTION

We sought to understand if the intervention would increase patient-level outcomes (receipt of tobacco treatment during hospitalization and at discharge; 6-month smoking abstinence) and improve hospital-wide performance on tobacco treatment metrics.

DESIGN AND METHODS

We conducted two retrospective quasi-experimental analyses to examine effectiveness of the TTC service. Using a pragmatic design and multivariable logistic regression, we compared patient-level outcomes of receipt of nicotine replacement therapy and 6-month quit rates between smokers seen by the service (n = 505) and eligible smokers not seen because of time constraints (n = 680) between July 2016 and December 2016. In addition, we conducted an interrupted time series analysis to examine the effect of the TTC service on hospital-level performance measures, comparing reported Joint Commission measure rates for inpatient (Tob-2) and postdischarge (Tob-3) tobacco treatment preimplementation (January 2015-June 2016) vs postimplementation (July 2016-December 2017) of the intervention.

RESULTS

Compared with inpatient smokers not seen by the TTC service, smokers seen by the TTC service had higher odds of receiving nicotine replacement during hospitalization (260 of 505 [51.5%] vs 244 of 680 [35.9%]; adjusted ORs [AOR], 1.93 [95% CI, 1.5-2.45]) and at discharge (164 of 505 [32.5%] vs 84 of 680 [12.4%]; AOR, 3.41 [95% CI, 2.54-4.61]), as well as higher odds of 6-month smoking abstinence (75 of 505 [14.9%] vs 68 of 680 [10%]; AOR, 1.48 [95% CI, 1.03-2.12]). Hospital-wide, the intervention was associated with a change in slope trends for Tob-3 (P < .01), but not for Tob-2.

INTERPRETATION

The "opt-out" electronic health record-based TTC service at our large safety net hospital was effective at improving both patient-level outcomes and hospital-level performance metrics, and could be implemented at other safety net hospitals that care for hard-to-reach smokers.

After Ringing the Bell: Receptivity of and Preferences for Healthy Behaviors in African American Dyads Surviving Lung Cancer

PURPOSE

To explore receptivity of and preferences for risk-reducing health behavior changes among African American survivors of early-stage lung cancer and their family members.

PARTICIPANTS & SETTING

26 African American non-small cell lung cancer survivor-family member dyads were recruited from two cancer programs in the southeastern United States.

METHODOLOGIC APPROACH

Social cognitive theory principles guided the design and implementation of focus groups. Descriptive statistics were used to summarize the data, and thematic analysis was used to interpret the transcripts from the focus groups.

FINDINGS

The following four themes were identified.

IMPLICATIONS FOR NURSING

Participants emphasized the need for improved provider communication. Pragmatic communication interventions for providers, survivors, and family members may facilitate behavior change and improve outcomes among underserved populations.

Improving pregnant women's diet and physical activity behaviours: the emergent role of health identity

Background

Women who gain too much weight in pregnancy are at increased risk of disease and of having children with increased risk. Interventions to improve health behaviours are usually designed for a general population of pregnant women, and trial outcomes show an average impact that does not represent the differences between individuals. To inform the development of future interventions, this study explored the factors that influenced women’s diet and physical activity during pregnancy and aimed to identify the needs of these women with regards to lifestyle support.

Methods

Women who completed a trial of vitamin D supplementation and nurse support in pregnancy were invited to take part in an interview. Seventeen women were interviewed about their lifestyles during pregnancy, the support they had, and the support they wanted. Interview transcripts were coded thematically and analysed to understand the factors that influenced the diets and physical activity levels of these women and their engagement with resources that could provide support.

Results

Women identified barriers to eating well or being physically active, and pregnancy-specific issues like nausea and pain were common. Women’s interest in maintaining a healthy lifestyle and their engagement with lifestyle support was related to the extent to which they self-identified as healthy people. Health-disengaged women were disinterested in talking about their lifestyles while health-focused women did not feel that they needed extra support. Women between these ends of the ‘health identity’ spectrum were interested in improving their health, and were able to identify barriers as well as sources of support.

Conclusions

Lifestyle interventions in pregnancy should be adapted to meet the needs of individuals with different health identities, and encouraging a change in health identity may be one way of supporting sustained change in health behaviours.

"I Already Know That Smoking Ain't Good for Me": Patient and Clinician Perspectives on Lung Cancer Screening Decision-Making Discussions as a Teachable Moment

BACKGROUND

Lung cancer screening (LCS) is now recommended for people at high risk of dying of lung cancer.

RESEARCH QUESTION

The purpose of this study was to use the LCS decision discussion as a case study to understand possible underlying components of a teachable moment to enhance motivation for smoking cessation.

STUDY DESIGN AND METHODS

The study investigated how patients and clinicians communicate about smoking. In-depth, semi-structured interviews were performed of the experiences of 51 individuals who formerly or currently smoked who were offered LCS and 24 clinicians. Only the baseline interviews were used because including the follow-up interviews would have been beyond the scope of this article. The interviews focused on communication about smoking, the perceived importance of discussing smoking and screening together, and patients' perceived challenges to smoking cessation.

RESULTS

Patients and clinicians differed in their views on the role of the LCS decision discussion as a teachable moment. Although clinicians felt that this discussion was a good opportunity to positively influence smoking behaviors, neither patients nor clinicians perceived the discussion as a teachable moment affecting smoking behaviors. Other motivating factors for smoking cessation were found.

INTERPRETATION

Our findings indicate that LCS decision discussions are not currently a teachable moment for behavior change in smoking cessation, but perhaps clinicians could address other aspects of communication to enhance motivation for cessation. Our hypothesized teachable moment model helps explain that there may not be sufficient emotional response elicited during the discussion to motivate a major behavior change such as smoking cessation.

Discrepancy between perceived diet quality and actual diet quality among US adult cancer survivors

OBJECTIVES

Little is known about cancer survivors' self-perception of their dietary quality compared with their measured diet quality and how those perceptions may influence their actual diet. This study aimed to fill this gap using national large datasets.

METHODS

National Health and Nutrition Examination Survey (NHANES) data from 2005 to 2014 were used. The healthy eating index (HEI) based on 24-h dietary recall was used to measure diet quality. Logistic regression models were fit to examine the influence of the misperception of eating healthiness on diet quality.

RESULTS

The agreement between self-perceived and actual diet quality was low (Kappa = 0.06, 95% CI: 0.02, 0.09) among cancer survivors. Over-rating diet quality was associated with a 5.39 lower total HEI score (P < 0.0001), 1.00 lower HEI score for empty calorie intake (P = 0.0028), 0.15 lower score for vegetable intake (P = 0.108), and 0.29 lower score for fruit intake; under-rating one's diet quality was associated with a 7.12 higher total HEI score (P < 0.0001), 2.57 higher HEI score for empty calorie intake (P < 0.0001), 0.02 higher score for vegetable intake (P = 0.904), and 0.84 higher score for fruit intake (P = 0.001). Our multinomial regression estimates suggested that each 10-year increase in age was associated with an increase in the odds of being an over-rater vs. a correct-rater (OR: 11.4, 95% CI: 10.01, 10.2). Hispanics were more likely than non-Hispanic whites to over-rate their diet quality (OR: 1.792, 95% CI: 1.062, 3.024).

CONCLUSIONS

Tailored nutrition interventions and guidance aimed at reducing the divergence between self-assessed and actual diet quality have the potential to improve cancer survivorship and narrow racial/ethnic and socioeconomic disparities.

Brief smoking cessation in acute Welsh hospitals: a realist approach

This implementation study sought to determine what works to support brief smoking cessation (BSC) in acute hospital settings, through exploration of organizational delivery and the role of healthcare professionals (HCPs). We used a realist approach, with embedded stakeholder engagement, within a large health organization. We conducted interviews (n = 27), a survey (n = 279) and organization documentation review (n = 44). The final programme theory suggests HCPs implement BSC when they value it as part of their role in contributing to improved patient outcomes; this is due to personal and professional influences, such as knowledge or experience. Organizational support, training and working in an environment where BSC is visible as standard care, positively influences implementation. However, the context exerts a strong influence on whether BSC is implemented, or not. HCPs make nuanced judgements on whether to implement BSC based on their assessment of the patient's responses, the patient's condition and other acute care demands. HCPs are less likely to implement BSC in dynamic and uncertain environments, as they are concerned about adversely impacting on the clinician-patient relationship and prioritize other acute care requirements. Organizations should actively promote BSC as a core function of the acute hospital setting and improve professional practice through leadership, training, feedback and visible indicators of organizational commitment. HCPs can be persuaded that implementing BSC is an acute care priority and an expectation of standard practice for improving patient outcomes.

Understanding the Prevalence of Smoking Among People Living with HIV (PLHIV) in Australia and Factors Associated with Smoking and Quitting

Understanding contributors to smoking and quitting cigarettes is important to developing effective cessation programs and addressing smoking related morbidity and mortality among people living with HIV (PLHIV). Using data from a large cross-sectional study of Australian PLHIV we provide a smoking prevalence estimate and explore the relationship between socio-demographic variables and smoking status. We also explore the relationship between HIV diagnosis and antiretroviral therapy (ART) initiation and quitting smoking. Of the 1011 respondents included in the analysis, 30.6% were current smokers. The strongest predictor of smoking was regular cannabis use (AOR 6.2, 95% CI 3.6-10.8) while the strongest predictor of being a past smoker was receiving ART (AOR 2.4, 95% CI 1.2-4.7). Quitting also increased around the time of diagnosis and ART initiation, highlighting the potential for these events to be optimal times to address smoking among PLHIV.

Patient-Physician Discussions on Lung Cancer Screening: A Missed Teachable Moment to Promote Smoking Cessation

INTRODUCTION

Little is known about whether patients and physicians perceive lung cancer screening (LCS) as a teachable moment to promote smoking cessation or the degree to which physicians in "real world" settings link LCS discussions with smoking cessation counseling. We sought to characterize patient and physician perspectives of discussions about smoking cessation during LCS.

METHODS

We conducted a qualitative study (interviews and focus groups) with 21 physicians and 28 smokers screened in four diverse hospitals. Transcripts were analyzed for characteristics of communication about smoking cessation and LCS, the perceived effect on motivation to quit smoking, the degree to which physicians leverage LCS as a teachable moment to promote smoking cessation, and suggestions to improve patient-physician communication about smoking cessation in the context of LCS.

RESULTS

Patients reported that LCS made them more cognizant of the health consequences of smoking, priming them for a teachable moment. While physicians and patients both acknowledged that smoking cessation counseling was frequent, they described little connection between their discussions regarding LCS and smoking cessation counseling. Physicians identified several barriers to integrating discussions on smoking cessation and LCS. They volunteered communication strategies by which LCS could be leveraged to promote smoking cessation.

CONCLUSIONS

LCS highlights the harms of smoking to patients who are chronic, heavy smokers and thus may serve as a teachable moment for promoting smoking cessation. However, this opportunity is typically missed in clinical practice.

IMPLICATIONS

LCS highlights the harms of smoking to heavily addicted smokers. Yet both physicians and patients reported little connection between LCS and tobacco treatment discussions due to multiple barriers. On-site tobacco treatment programs and post-screening messaging tailored to the LCS results are needed to maximize the health outcomes of LCS, including smoking quit rates and longer-term smoking-related morbidity and mortality.

Pharmacological interventions for promoting smoking cessation during pregnancy

BACKGROUND

Tobacco smoking in pregnancy causes serious health problems for the developing fetus and mother. When used by non-pregnant smokers, pharmacotherapies (nicotine replacement therapy (NRT), bupropion, and varenicline) are effective for increasing smoking cessation, however their efficacy and safety in pregnancy remains unknown. Electronic cigarettes (ECs) are becoming widely used, but their efficacy and safety when used for smoking cessation in pregnancy are also unknown.

OBJECTIVES

To determine the efficacy and safety of smoking cessation pharmacotherapies and ECs used during pregnancy for smoking cessation in later pregnancy and after childbirth, and to determine adherence to smoking cessation pharmacotherapies and ECs for smoking cessation during pregnancy.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 May 2019), trial registers, and grey literature, and checked references of retrieved studies.

SELECTION CRITERIA

Randomised controlled trials (RCTs) conducted in pregnant women, comparing smoking cessation pharmacotherapy or EC use with either placebo or no pharmacotherapy/EC control. We excluded quasi-randomised, cross-over, and within-participant designs, and RCTs with additional intervention components not matched between trial arms.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane methods. The primary efficacy outcome was smoking cessation in later pregnancy; safety was assessed by 11 outcomes (principally birth outcomes) that indicated neonatal and infant well-being. We also collated data on adherence to trial treatments. We calculated the risk ratio (RR) or mean difference (MD) and the 95% confidence intervals (CI) for each outcome for each study, where possible. We grouped eligible studies according to the type of comparison. We carried out meta-analyses where appropriate.

MAIN RESULTS

We included 11 trials that enrolled a total of 2412 pregnant women who smoked at enrolment, nine trials of NRT and two trials of bupropion as adjuncts to behavioural support, with comparable behavioural support provided in the control arms. No trials investigated varenicline or ECs. We assessed four trials as at low risk of bias overall. The overall certainty of the evidence was low across outcomes and comparisons as assessed using GRADE, with reductions in confidence due to risk of bias, imprecision, and inconsistency. Compared to placebo and non-placebo (behavioural support only) controls, there was low-certainty evidence that NRT increased the likelihood of smoking abstinence in later pregnancy (RR 1.37, 95% CI 1.08 to 1.74; I² = 34%, 9 studies, 2336 women). However, in subgroup analysis by comparator type, there was a subgroup difference between placebo-controlled and non-placebo controlled RCTs (test for subgroup differences P = 0.008). There was unclear evidence of an effect in placebo-controlled RCTs (RR 1.21, 95% CI 0.95 to 1.55; I² = 0%, 6 studies, 2063 women), whereas non-placebo-controlled trials showed clearer evidence of a benefit (RR 8.55, 95% CI 2.05 to 35.71; I² = 0%, 3 studies, 273 women). An additional subgroup analysis in which studies were grouped by the type of NRT used found no difference in the effectiveness of NRT in those using patches or fast-acting NRT (test for subgroup differences P = 0.08). There was no evidence of a difference between NRT and control groups in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care, caesarean section, congenital abnormalities, or neonatal death. In one study infants born to women who had been randomised to NRT had higher rates of 'survival without developmental impairment' at two years of age compared to the placebo group. Non-serious adverse effects observed with NRT included headache, nausea, and local reactions (e.g. skin irritation from patches or foul taste from gum), but data could not be pooled. Adherence to NRT treatment regimens was generally low. We identified low-certainty evidence that there was no difference in smoking abstinence rates observed in later pregnancy in women using bupropion when compared to placebo control (RR 0.74, 95% CI 0.21 to 2.64; I² = 0%, 2 studies, 76 women). Evidence investigating the safety outcomes of bupropion use was sparse, but the existing evidence showed no difference between the bupropion and control group.

AUTHORS' CONCLUSIONS

NRT used for smoking cessation in pregnancy may increase smoking cessation rates in late pregnancy. However, this evidence is of low certainty, as the effect was not evident when potentially biased, non-placebo-controlled RCTs were excluded from the analysis. Future studies may therefore change this conclusion. We found no evidence that NRT has either positive or negative impacts on birth outcomes; however, the evidence for some of these outcomes was also judged to be of low certainty due to imprecision and inconsistency. We found no evidence that bupropion may be an effective aid for smoking cessation during pregnancy, and there was little evidence evaluating its safety in this population. Further research evidence on the efficacy and safety of pharmacotherapy and EC use for smoking cessation in pregnancy is needed, ideally from placebo-controlled RCTs that achieve higher adherence rates and that monitor infants' outcomes into childhood. Future RCTs of NRT should investigate higher doses than those tested in the studies included in this review.

Type 2 diabetes and colorectal cancer screening: Findings from the English Longitudinal Study of Ageing

Objectives

Type 2 diabetes has been identified as a risk factor for colorectal cancer, but little is known about whether it influences participation in colorectal cancer screening programmes. This study tested the extent to which Type 2 diabetes is negatively associated with colorectal cancer screening uptake.

Methods

We analysed individual data of screening eligible men and women aged 60–75 without cancer diagnosis from wave 6 of the English Longitudinal Study of Ageing (collected 2012–2013), to investigate whether Type 2 Diabetes influences colorectal cancer screening behaviour independently of demographic characteristics, body mass index, socio-economic status and other chronic diseases.

Results

Individuals who reported to have Type 2 diabetes or had glycated haemoglobin (HbA1c) levels of 48 mmol/mol or higher were less likely to have ever completed a screening test (faecal occult blood test; 62.8% vs. 75.8%, p < 0.01) or to be up-to-date with their biennial screening invitation (60.2% vs. 72.0%, p < 0.05). The negative associations of Type 2 diabetes on colorectal cancer screening were found both in unadjusted and adjusted regression models.

Conclusions

Future qualitative and quantitative research should identify reasons for this discrepancy, to inform interventions to increase screening uptake in this high-risk population.

Remote Therapy to Improve Outcomes in Lung Transplant Recipients: Design of the INSPIRE-III Randomized Clinical Trial

BACKGROUND

Impaired functional capacity and emotional distress are associated with lower quality of life (QoL) and worse clinical outcomes in post lung transplant patients. Strategies to increase physical activity and reduce distress are needed.

METHODS

The Investigational Study of Psychological Interventions in Recipients of Lung Transplant-III study is a single site, parallel group randomized clinical trial in which 150 lung transplant recipients will be randomly assigned to 3 months of telephone-delivered coping skills training combined with aerobic exercise (CSTEX) or to a Standard of Care plus Education control group. The primary endpoints are a global measure of distress and distance walked on the 6-Minute Walk Test. Secondary outcomes include measures of transplant-specific QoL, frailty, health behaviors, and chronic lung allograft dysfunction-free survival.

RESULTS

Participants will be evaluated at baseline, at the conclusion of 3 months of weekly treatment, at 1-year follow-up, and followed annually thereafter for clinical events for up to 4 years (median = 2 y). We also will determine whether functional capacity, distress, and health behaviors (eg, physical activity, medication adherence, and volume of air forcefully exhaled in 1 second (FEV1), mediate the effects of the CSTEX intervention on clinical outcomes.

CONCLUSIONS

Should the CSTEX intervention result in better outcomes compared with the standard of care plus post-transplant education, the remotely delivered CSTEX intervention can be made available to all lung transplant recipients as a way of enhancing their QoL and improving clinical outcomes.

Leveraging the Mammography Setting to Raise Awareness and Facilitate Referral to Lung Cancer Screening: A Qualitative Analysis

PURPOSE

Despite compelling support for the benefits of low-dose CT (LDCT) screening for lung cancer among high-risk individuals, awareness of LDCT screening and uptake remain low. The aim of this project was to explore the perspectives of ACR mammography screening program directors (MPDs) regarding efforts to raise LDCT screening awareness and appropriate referrals by identifying high-risk individuals participating in routine mammography.

METHODS

MPDs were recruited from ACR-accredited mammography facilities to participate in semistructured interviews after the completion of an online survey. Interviews were conducted over the telephone, recorded, transcribed, and subsequently reviewed for accuracy. Twenty MPDs were interviewed, and 18 interviews were transcribed and included in the thematic analysis. A theme codebook was developed, and all interviews were coded using NVivo by two trained reviewers.

RESULTS

Key themes were organized into four broad domains: (1) general attitudes toward the integration of LDCT screening, (2) identifying mammography patients at high risk for lung cancer, (3) counseling about LDCT screening, and (4) strategies to identify high-risk women and increase awareness and knowledge of LDCT screening. Overall, MPDs recognized the benefits of integrating mammography and LDCT screening and were receptive to educating and referring women for LDCT screening. However, training and workflow changes are needed to ensure successful implementation.

CONCLUSIONS

Qualitative data suggest that MPDs are amenable to leveraging the mammography setting to engage women about LDCT screening; however, additional tools, training, and/or staffing may be necessary to leverage the full potential of reaching women at high risk for lung cancer within the context of mammographic screening.

Factors Associated with the Leisure-Time Physical Activity (LTPA) during the First Trimester of the Pregnancy: The Cross-Sectional Study among Pregnant Women in Serbia

Background: The benefits of physical activity during pregnancy include lower maternal weight gain, a lower likelihood of gestational diabetes, low back pain, preeclampsia, preterm delivery, caesarian delivery, and macrosomia. This study aimed to examine the factors associated with insufficient leisure-time physical activity (LTPA) during the first trimester. Methods: A cross-sectional study was conducted at the Clinic for Obstetrics and Gynecology of Clinical Center of Serbia, Belgrade, between January and June of 2018. The final analyses included 162/175 pregnant women. The questionnaire was used to obtain social characteristics, pregnancy, and lifestyle characteristics (Pregnancy Risk Assessment Monitoring System-PRAMS), pre-pregnancy LTPA (International Physical Activity Questionnaire-IPAQ), and LTPA during the first trimester (Pregnancy Physical Activity Questionnaire-PPAQ). Women were classified into two groups of sufficient and insufficient LTPA during the first trimester based on the recommendations of the World Health Organization. Multivariate logistic regression analysis was applied. Results: A total of 27.2% of the women had insufficient LTPA during pregnancy. Insufficient LTPA during pregnancy was associated with <12 years of education (OR: 2.3, 95% CI: 1.05-5.04), self-rated financial status as poor (OR: 0.34, 95% CI: 0.14-0.79), and hours spent walking before pregnancy (OR: 0.87, 95% CI: 0.77-0.99). Conclusions: Our results can help direct health care professionals advice for women who are planning pregnancy towards walking as it seems to be sustained during pregnancy.

The value of teachable moments in surgical patient care and the supportive role of digital technologies

Evidence strongly supports improved outcomes following surgery when patients are more physically active, have better dietary intake, or are generally fitter prior to surgery. Having an operation is a major life event for patients, and many are not educated around what they can do as individuals to aid a speedier and more successful recovery following their operation. What if there was a time point before surgery where clinicians could inspire patients to adjust their lifestyles for the better, in order to see fewer complications after surgery? This is where the concept of teachable moments comes into play.

This commentary explores the concept of teachable moments and their value in surgical patient care and discusses the potentially under-utilized opportunities on hand to the surgical multidisciplinary team to remotely support patients using digital health technologies.

Fathers' Views and Experiences of Creating a Smoke-Free Home: A Scoping Review

Enabling parents to create a smoke-free home is one of the key ways that children's exposure to second-hand smoke (SHS) can be reduced. Smoke-free home interventions have largely targeted mothers who smoke, and there is little understanding of the barriers and facilitators that fathers experience in creating a smoke-free home. Systematic searches combining terms for fathers, homes, and SHS exposure were run in April 2019 in Web of Science's Citation Indices, PsycINFO, and PubMed for English-language studies published since 2008. The searches identified 980 records for screening, plus 66 records from other sources. Twelve studies reported in 13 papers were included in this scoping review. Eight of the studies were conducted in Asian countries (five in China, one in India, one in Japan, and one in Iran), three were conducted in Canada, and one in Turkey. Findings were extracted in verbatim text for thematic analysis. The review identified that attitudes and knowledge, cultural and social norms, gender power relations, and shifting perceptions and responsibilities related to fatherhood can impact on fathers' views of their role in relation to creating and maintaining a smoke-free home. There were too few published studies that had assessed smoke-free home interventions with fathers to draw conclusions regarding effective approaches. Research is clearly needed to inform our understanding of fathers' roles, successes and challenges in creating and maintaining a smoke-free home, so that father-inclusive rather than mother-led interventions can be developed to benefit entire households and improve gender equity as well as health.

The association between smokers' self-reported health problems and quitting: Findings from the ITC Four Country Smoking and Vaping Wave 1 Survey

INTRODUCTION

This study aimed to systematically examine whether having health conditions or concerns related to smoking are associated with quitting activities among smokers across four western countries.

METHODS

Data came from the 2016 International Tobacco Control Four Country Smoking and Vaping Survey conducted in Australia, Canada, England and US. We asked smokers and recent quitters (n=11838) whether they had a medical diagnosis for heart disease, cancer, chronic lung disease, depression, anxiety, alcohol problems, diabetes, severe obesity and chronic pain (nine conditions), and whether they believed smoking had harmed/would harm their health, along with questions on quitting activities.

RESULTS

General concerns about smoking harming health and all specific health conditions, except for alcohol problems, were positively associated with quit attempts, but the relationships between health conditions and other quitting measures (being abstinent, planning to quit, use of quitting medications) were less consistent. Positive associations between conditions and use of quitting medications were only significant for depression, anxiety and chronic pain (adjusted odds ratios ranged from 1.4 to 1.5). There was a general tendency to report lower self-efficacy for quitting among those with the health conditions.

CONCLUSIONS

While those with smoking related conditions are somewhat more aware of the links to their smoking, and are largely taking more action, the extent of this is lower than one might reasonably expect. Enhanced awareness campaigns are needed and health professionals need to do more to use health conditions to motivate quit attempts and to ensure they are made with the most effective forms of help.

Cohort Profile: The Dutch Perined-Lifelines birth cohort

BACKGROUND

Maternal nutrition status (e.g. dietary/nutrient intake) during pregnancy has been associated with pregnancy outcomes including birth weight, infant survival and metabolic health of the offspring during later life. During the past few years, maternal dietary intake, at least three months before conception, has been shown to affect pregnancy outcomes also. However, literature investigating this link is still scarce. The studies that have looked at preconception dietary intake in relation to pregnancy outcome were either animal studies, had small sample sizes or focused on only selected macronutrient intake rather than complete (macro)nutrient composition or dietary intakes (e.g. food groups). Therefore, we aim to investigate the association between preconception diet and pregnancy outcomes in a linked birth cohort. The main objective of this manuscript is to describe the methodology of establishing this birth cohort and to describe both the characteristics of the study population included as well as the representativeness in terms of dietary intake.

METHODS

We created the birth cohort by linking two existing databases; a large population-based cohort study in the Netherlands (The Lifelines Cohort study) and the Dutch national birth registry (Perined), through a 'trusted third party'. The birth cohort contains information on maternal dietary intake during preconception as well as pregnancy outcomes.

RESULTS AND DISCUSSION

In the Lifelines Cohort study, 3,418 pregnancies were available for linking with Perined. In total, 2,368 pregnancies (86.9%) were linked with Perined, resulting in the birth cohort. With this linked cohort we are able to provide insights on the associations between dietary intake before conception and pregnancy outcomes. Such data could potentially improve nutritional care for women of childbearing age. Lifestyle changes in the period preceding pregnancy may be most effective in improving pregnancy outcomes. A focus on this window of opportunity may provide both sufficient time, as well as a period when women are potentially motivated to adopt health optimizing behaviours.

E-cigarettes and Smoking Cessation in Smokers With Chronic Conditions

INTRODUCTION

Many smokers with chronic medical conditions use e-cigarettes. This study assessed the association between e-cigarette use and subsequent smoking-cessation efforts in adult smokers with and without chronic medical conditions.

METHODS

This was a longitudinal cohort study of adult cigarette smokers using Waves 1 and 2 of the Population Assessment of Tobacco and Health Study (2013-2015), analyzed in 2018‒2019. The exposure was the initiation of e-cigarette use by Wave 2. The outcomes at Wave 2 were: (1) past 12-month attempts to quit, (2) cigarette abstinence, (3) ≥50% reduction in cigarette use, and (4) past 12-month use of evidence-based smoking-cessation treatment.

RESULTS

E-cigarette use initiation was associated with increased odds of attempting to quit smoking at Wave 2 among smokers with any chronic medical condition (AOR=1.92, 95% CI=1.42, 2.59) and without chronic medical conditions (AOR=1.81, 95% CI=1.50, 2.18). E-cigarette use initiation was also significantly associated with Wave 2 smoking abstinence in smokers with (AOR=1.95, 95% CI=1.11, 3.43) and without chronic medical conditions (AOR=1.63, 95% CI=1.17, 2.28).

CONCLUSIONS

At a population level, e-cigarette use by smokers with chronic medical conditions is associated with more quitting activity and smoking abstinence. Future studies are needed to assess e-cigarette safety and efficacy to determine whether they may provide an alternative smoking-cessation or harm-reduction strategy for adults with smoking-sensitive disease who cannot achieve these goals with other methods.

Correlates of substance use in pregnant women under community supervision after conviction for a criminal offence: The role of psychological distress

BACKGROUND

Being pregnant while under community supervision after conviction for a criminal offence can be a highly stressful experience, and pregnant women under community supervision are at an elevated risk for substance use.

AIMS/HYPOTHESES

To test for relationships between psychological distress and use of tobacco, alcohol, or marijuana during the month prior to a research assessment among pregnant women under community supervision, controlling for demographic characteristics.

METHODS

Data from the National Survey on Drug Use and Health were aggregated for the years 2008-2016, inclusive. Logistic regression analyses were conducted to examine correlates of past-month use of each substance.

RESULTS

Of all 505,796 people in the survey, 6,974 were pregnant women of whom 280 reported being under community supervision for a criminal offence; relevant data were available for 271 of these cases. The pregnant women under community supervision reported higher rates of past-month substance use of each kind and of psychological distress than pregnant women not under community supervision. Past-month serious psychological distress, but not remitted psychological distress, corresponded strongly with past-month alcohol use even when controlling for demographic characteristics and other substance use.

CONCLUSIONS

Our findings add to the very sparse literature about a group of women likely to be exceptionally vulnerable during pregnancy and underscore the importance of screening for symptoms of substance use and of psychological distress amongst them. Among women under community supervision, alcohol use was less likely in the second or third trimester than the first, but as those using alcohol were more likely to report past month psychological distress, it may be important to provide additional resources and treatment services for these women.

Behavioral health risk factor profiles in general hospital patients: identifying the need for screening and brief intervention

BACKGROUND

Little is known about the clustering of behavioral health risk factors (HRFs), namely the occurrence of 16 specific combinations of tobacco smoking, at-risk alcohol use, overweight and physical inactivity in general hospital patients. Furthermore, social inequalities in HRFs, health and life expectancy are a major concern in public health. In order to establish the need for screening and intervention in general hospital care, the study aimed to determine the co-occurrence of HRFs in patients in four medical departments, and to investigate differences by gender, age and socio-economic characteristics.

METHODS

Over 17 months, a systematic multiple HRF screening was conducted at one general hospital in northeastern Germany. In total, 6251 18-64 year old patients (92% of eligibles) participated. Proportions and confidence intervals were calculated for all 16 HRF profiles stratified by department, gender, age group, school education, and employment status.

RESULTS

In total, 92.2% of the participants (58.6% male) reported ≥1 HRF, and 65.7% ≥2 HRFs. Men (71.2%), patients aged 35-49 (67.9%) and 50-64 years (69.5%), lower educated (79.0%), and unemployed (77.8%) patients had larger proportions of ≥2 HRFs than their counterparts. In all departments, the most common HRF profiles included overweight. HRF profiles that included alcohol and/ or smoking were more common in ear-nose-throat and trauma surgery than in internal medicine and general surgery patients. Men had higher rates concerning almost all HRF profiles including ≥2 HRFs and alcohol; women concerning profiles that included ≤2 HRFs and inactivity. In older patients, profiles with ≥2 HRFs including overweight; and in younger patients, profiles with smoking and/or alcohol were more common. In lower educated patients, profiles with ≥2 HRFs including inactivity; and in higher educated patients profiles with ≤2 HRFs including alcohol were more common. Compared to others, unemployed patients had higher rates of profiles with ≥3 HRFs including smoking.

CONCLUSIONS

Two in three patients require interventions targeting two or more HRFs. The findings help to develop screening and brief intervention for patients with specific health risk profiles, that can reach most patients, including those most in need and those most hard to reach, with socio-economically disadvantaged people in particular.

Preeclampsia, gestational diabetes and later risk of cardiovascular disease: Women's experiences and motivation for lifestyle changes explored in focus group interviews

BACKGROUND

Preeclampsia (PE) and gestational diabetes mellitus (GDM) are both associated with increased risk of future cardiovascular disease (CVD). Knowledge of the relationship between these pregnancy complications and increased CVD risk enables early prevention through lifestyle changes. This study aimed to explore women's experiences with PE and/or GDM, and their motivation and need for information and support to achieve lifestyle changes.

METHODS

Systematic text condensation was used for thematic analysis of meaning and content of data from five focus group interviews with 17 women with PE and/or GDM, with a live birth between January 2015 and October 2017.

RESULTS

This study provides new knowledge of how women with GDM and/or PE experience pregnancy complications in a Nordic healthcare model. It reveals the support they want and the important motivating factors for lifestyle change. We identified six themes: Trivialization of the diagnosis during pregnancy; Left to themselves to look after their own health; The need to process the shock before making lifestyle changes (severe PE); A desire for information about future disease risk and partner involvement; Practical solutions in a busy life with a little one, and; Healthcare professionals can reinforce the turning point. The women with GDM wanted healthcare professionals to motivate them to continue the lifestyle changes introduced during pregnancy. Those with severe PE felt a need for individualized care to ensure that they had processed their traumatic labor experiences before making lifestyle changes. Participants wanted their partner to be routinely involved to ensure a joint understanding of the need for lifestyle changes. Motivation for lifestyle changes in pregnancy was linked to early information and seeing concrete results.

CONCLUSIONS

Women with PE and GDM have different experiences of diagnosis and treatment, which will affect the follow-up interventions to reduce future CVD risk through lifestyle change. For GDM patients, lifestyle changes in pregnancy should be reinforced and continued postpartum. Women with PE should be informed by their general practitioner after birth, and given a plan for lifestyle change. Those with severe PE will need help in processing the trauma, and stress management should be routinely offered.

The Incentives to Quit tobacco in Pregnancy (IQuiP) protocol: piloting a financial incentive-based smoking treatment for women attending substance use in pregnancy antenatal services

INTRODUCTION

While tobacco smoking prevalence is falling in many western societies, it remains elevated among high-priority cohorts. Rates up to 95% have been reported in women whose pregnancy is complicated by other substance use. In this group, the potential for poor pregnancy outcomes and adverse physical and neurobiological fetal development are elevated by tobacco smoking. Unfortunately, few targeted and effective tobacco dependence treatments exist to assist cessation in this population. The study will trial an evidence-based, multicomponent tobacco smoking treatment tailored to pregnant women who use other substances. The intervention comprises financial incentives for biochemically verified abstinence, psychotherapy delivered by drug and alcohol counsellors, and nicotine replacement therapy. It will be piloted at three government-based, primary healthcare facilities in New South Wales (NSW) and Victoria, Australia. The study will assess the feasibility and acceptability of the treatment when integrated into routine antenatal care offered by substance use in pregnancy antenatal services.

METHODS AND ANALYSIS

The study will use a single-arm design with pre-post comparisons. One hundred clients will be recruited from antenatal clinics with a substance use in pregnancy service. Women must be <33 weeks' gestation, ≥16 years old and a current tobacco smoker. The primary outcomes are feasibility, assessed by recruitment and retention and the acceptability of addressing smoking among this population. Secondary outcomes include changes in smoking behaviours, the comparison of adverse maternal outcomes and neonatal characteristics to those of a historical control group, and a cost-consequence analysis of the intervention implementation.

ETHICS AND DISSEMINATION

Protocol approval was granted by Hunter New England Human Research Ethics Committee (Reference 17/04/12/4.05), with additional ethical approval sought from the Aboriginal Health and Medical Research Council of NSW (Reference 1249/17). Findings will be disseminated via academic conferences, peer-reviewed publications and social media.

Interventions for pregnant women who use tobacco and other substances: a systematic review protocol

INTRODUCTION

The prevalence of tobacco smoking in pregnancy remains elevated in some disadvantaged populations of women. One group is those who use alcohol and/or other psychoactive substances during pregnancy, with tobacco use prevalence estimates ranging from 71% to 95%. Although effective evidence-based cessation treatments exist, few women with co-occurring substance use problems successfully stop smoking during pregnancy. There is limited information about treatments that specifically target this group and a summary of the available research is required to assist and enhance the development of innovative cessation interventions. This article describes a protocol for a comprehensive review of studies that have trialled behavioural and/or pharmacological tobacco cessation interventions in populations of pregnant women who are nicotine dependent and use alcohol and/or other psychoactive substances.

METHODS AND ANALYSIS

The review will undertake literature searches in MEDLINE, PsycINFO, CINAHL, EMBASE and ProQuest databases, as well as the grey literature. Studies of any design methodology will be included if they describe changes to tobacco smoking behaviours in quantitative terms. No restriction on year of publication or published language will apply. Participants include pregnant women of any age, who smoke tobacco, who are seeking or having treatment, or in post-treatment recovery for the use of psychoactive substances. Interventions are any psychological, behavioural or pharmacological treatments used to treat tobacco use. Outcome measures are any that quantitatively report abstinence or reductions in participant tobacco consumption. Key details and tobacco-related outcomes from included studies will be extracted and tabulated before being narratively synthesised. The systematic review protocol has been developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines.

ETHICS AND DISSEMINATION

Ethics approval is not required. Findings will be disseminated via peer-reviewed literature, conference presentations, media and social media.

Is a Hypertension Diagnosis Associated With Improved Dietary Outcomes Within 2 to 4 Years? A Fixed-Effects Analysis From the China Health and Nutrition Survey

Background Evidence shows that dietary factors play an important role in blood pressure. However, there is no clear understanding of whether hypertension diagnosis is associated with dietary modifications. The aim of this study is to estimate the longitudinal association between hypertension diagnosis and subsequent changes (within 2-4 years) in dietary sodium, potassium, and sodium-potassium (Na/K) ratio. Methods and Results We included adults (18-75 years, n=16 264) from up to 9 waves (1991-2015) of the China Health and Nutrition Survey. Diet data were collected using three 24-hour dietary recalls and a household food inventory. We used fixed-effects models to estimate the association between newly self-reported diagnosed hypertension and subsequent within-individual changes in sodium, potassium, and Na/K ratio. We also examined changes among couples and at the household level. Results suggest that on average, men who were diagnosed with hypertension decreased their sodium intake by 251 mg/d and their Na/K ratio by 0.19 within 2 to 4 years after diagnosis (P<0.005). Among spouse pairs, sodium intake and Na/K ratio of women decreased when their husbands were diagnosed (P<0.05). Household average sodium density and Na/K ratio decreased, and household average potassium density increased after a man was diagnosed. In contrast, changes were not statistically significant when women were diagnosed. Conclusions Our findings suggest that hypertension diagnosis for a man may result in modest dietary improvements for him, his wife, and other household members. Yet, diagnosis for a woman does not seem to result in dietary changes for her or her household members.

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.

Examining the Use of Glucose and Physical Activity Self-Monitoring Technologies in Individuals at Moderate to High Risk of Developing Type 2 Diabetes: Randomized Trial

BACKGROUND

Self-monitoring of behavior (namely, diet and physical activity) and physiology (namely, glucose) has been shown to be effective in type 2 diabetes (T2D) and prediabetes prevention. By combining self-monitoring technologies, the acute physiological consequences of behaviors could be shown, prompting greater consideration to physical activity levels today, which impact the risk of developing diabetes years or decades later. However, until recently, commercially available technologies have not been able to show individuals the health benefits of being physically active.

OBJECTIVE

The objective of this study was to examine the usage, feasibility, and acceptability of behavioral and physiological self-monitoring technologies in individuals at risk of developing T2D.

METHODS

A total of 45 adults aged ≥40 years and at moderate to high risk of T2D were recruited to take part in a 3-arm feasibility trial. Each participant was provided with a behavioral (Fitbit Charge 2) and physiological (FreeStyle Libre flash glucose monitor) monitor for 6 weeks, masked according to group allocation. Participants were allocated to glucose feedback (4 weeks) followed by glucose and physical activity (biobehavioral) feedback (2 weeks; group 1), physical activity feedback (4 weeks) followed by biobehavioral feedback (2 weeks; group 2), or biobehavioral feedback (6 weeks; group 3). Participant usage (including time spent on the apps and number of glucose scans) was the primary outcome. Secondary outcomes were the feasibility (including recruitment and number of sensor displacements) and acceptability (including monitor wear time) of the intervention. Semistructured qualitative interviews were conducted at the 6-week follow-up appointment.

RESULTS

For usage, time spent on the Fitbit and FreeStyle Libre apps declined over the 6 weeks for all groups. Of the FreeStyle Libre sensor scans conducted by participants, 17% (1798/10,582) recorded rising or falling trends in glucose, and 24% (13/45) of participants changed ≥1 of the physical activity goals. For feasibility, 49% (22/45) of participants completed the study using the minimum number of FreeStyle Libre sensors, and a total of 41 sensors were declared faulty or displaced. For acceptability, participants wore the Fitbit for 40.1 (SD 3.2) days, and 20% (9/45) of participants and 53% (24/45) of participants were prompted by email to charge or sync the Fitbit, respectively. Interviews unearthed participant perceptions on the study design by suggesting refinements to the eligibility criteria and highlighting important issues about the usability, wearability, and features of the technologies.

CONCLUSIONS

Individuals at risk of developing T2D engaged with wearable digital health technologies providing behavioral and physiological feedback. Modifications are required to both the study and to commercially available technologies to maximize the chances of sustained usage and behavior change. The study and intervention were feasible to conduct and acceptable to most participants.

Just-in-Time Adaptive Interventions (JITAIs) in Mobile Health: Key Components and Design Principles for Ongoing Health Behavior Support

Background

The just-in-time adaptive intervention (JITAI) is an intervention design aiming to provide the right type/amount of support, at the right time, by adapting to an individual's changing internal and contextual state. The availability of increasingly powerful mobile and sensing technologies underpins the use of JITAIs to support health behavior, as in such a setting an individual's state can change rapidly, unexpectedly, and in his/her natural environment.

Purpose

Despite the increasing use and appeal of JITAIs, a major gap exists between the growing technological capabilities for delivering JITAIs and research on the development and evaluation of these interventions. Many JITAIs have been developed with minimal use of empirical evidence, theory, or accepted treatment guidelines. Here, we take an essential first step towards bridging this gap.

Methods

Building on health behavior theories and the extant literature on JITAIs, we clarify the scientific motivation for JITAIs, define their fundamental components, and highlight design principles related to these components. Examples of JITAIs from various domains of health behavior research are used for illustration.

Conclusions

As we enter a new era of technological capacity for delivering JITAIs, it is critical that researchers develop sophisticated and nuanced health behavior theories capable of guiding the construction of such interventions. Particular attention has to be given to better understanding the implications of providing timely and ecologically sound support for intervention adherence and retention.

Treating Parents for Tobacco Use in the Pediatric Setting: The Clinical Effort Against Secondhand Smoke Exposure Cluster Randomized Clinical Trial

IMPORTANCE

Despite the availability of free and effective treatment, few pediatric practices identify and treat parental tobacco use.

OBJECTIVE

To determine if the Clinical Effort Against Secondhand Smoke Exposure (CEASE) intervention can be implemented and sustained in pediatric practices and test whether implementing CEASE led to changes in practice-level prevalence of smoking among parents over 2 years.

DESIGN, SETTING, AND PARTICIPANTS

This cluster randomized clinical trial was conducted from April 2015 to October 2017. Ten pediatric practices in 5 states were randomized to either implement the CEASE protocol or maintain usual care (as a control group). All parents who screened positive for tobacco use by exit survey after their child's clinical visit 2 weeks (from April to October 2015) and 2 years after intervention implementation (April to October 2017) were eligible to participate. Data analysis occurred from January 2018 to March 2019.

INTERVENTIONS

The CEASE intervention is a practice-change intervention designed to facilitate both routine screening in pediatric settings of families for tobacco use and delivery of tobacco cessation treatment to individuals in screened households who use tobacco.

MAIN OUTCOMES AND MEASURES

The primary outcome was delivery of meaningful tobacco treatment, defined as the prescription of nicotine replacement therapy or quit line enrollment. Furthermore, changes in practice-level smoking prevalence and cotinine-confirmed quit rates over the 2 years of intervention implementation were assessed.

RESULTS

Of the 8184 parents screened after their child's visit 2 weeks after intervention implementation, 961 (27.1%) were identified as currently smoking in intervention practices; 1103 parents (23.9%) were currently smoking in control practices. Among the 822 and 701 eligible parents who completed the survey in intervention and control practices, respectively 364 in the intervention practices (44.3%) vs 1 in a control practice (0.1%) received meaningful treatment at that visit (risk difference, 44.0% [95% CI, 9.8%-84.8%]). Two years later, of the 9794 parents screened, 1261 (24.4%) in intervention practices and 1149 (25.0%) in control practices were identified as currently smoking. Among the 804 and 727 eligible parents completing the survey in intervention and control practices, respectively, 113 in the intervention practices (14.1%) vs 2 in the control practices (0.3%) received meaningful treatment at that visit (risk difference, 12.8% [95% CI, 3.3%-37.8%]). Change in smoking prevalence over the 2 years of intervention implementation favored the intervention (-2.7% vs 1.1%; difference -3.7% [95% CI, -6.3% to -1.2%]), as did the cotinine-confirmed quit rate (2.4% vs -3.2%; difference, 5.5% [95% CI, 1.4%-9.6%]).

CONCLUSIONS AND RELEVANCE

In this trial, integrating screening and treatment for parental tobacco use in pediatric practices showed both immediate and long-term increases in treatment delivery, a decline in practice-level parental smoking prevalence, and an increase in cotinine-confirmed cessation, compared with usual care.

Motivational Communication in Dental Practices: Prevention and Management of Caries over the Life Course

Dental caries and periodontal diseases are preventable. Nevertheless, they remain prevalent. Dental practices offer an ideal setting for educating patients about oral health-related behavior change. This article describes the motivational communication approach to changing behavior and applies it to a discussion of behavior change communication over the course of life. CONTENT considerations focus on on identifying high-priority behaviors for change; patient affect, behavior, and cognition related to these behaviors, and understanding in which stage of change the patient is. Process the four principles of the Motivational Interviewing approach by Miller & Rollnick to analyze oral health-related behavior change over the life course.

HIV Care Initiation: A Teachable Moment for Smoking Cessation?

Introduction

Tobacco use among persons living with HIV represents an important risk factor for poor treatment outcomes, morbidity, and mortality. Thus, efforts designed to inform the development of appropriate smoking cessation programs for this population remains a public health priority. To address this need, a study was conducted to longitudinally assess the relationship between intention to quit smoking and cessation over the 12-month period following initiation of HIV care.

Methods

Patients initiating HIV care at a large inner city safety net clinic were enrolled (n = 378) in a 12-month prospective study. Audio computer-assisted self-interviews were conducted at baseline, and at 3, 6, 9, and 12 months post-enrollment, and HIV-related clinical data were collected from participants' electronic medical records. Variables of interest included intention to quit smoking, 7-day point prevalence smoking abstinence (biochemically verified), and stage of HIV. Data were collected in Houston, Texas from 2009 to 2015.

Results

The sample was 75% male and 62% Black. Findings indicated that intention to quit smoking increased between baseline and 3 months, and subsequently trended downward from 3 to 12 months. Results from linear and generalized linear mixed models indicated that participants with advanced HIV disease (vs. not advanced) reported significantly (p < .05) higher intention to quit smoking at 3, 6, and 12 months post-study enrollment. A similar though nonsignificant pattern was observed in the smoking abstinence outcome.

Conclusions

HIV treatment initiation appears to be associated with increases in intention to quit smoking thus serves as a potential teachable moment for smoking cessation intervention.

Implications

This study documents significant increases in intention to quit smoking in the 3-month period following HIV care initiation. Moreover, quit intention trended downward following the 3-month follow-up until the 12-month follow-up. In addition, a marked effect for HIV disease stage was observed, whereby participants with advanced HIV disease (vs. those without) experienced a greater increase in intention to quit. HIV treatment initiation appears to be associated with increases in intention to quit smoking, thus serves as a crucial teachable moment for smoking cessation intervention for people living with HIV.

Perceived threats, benefits and barriers of e-cigarette use during pregnancy. A qualitative analysis of risk perception within existing threads in online discussion forums

OBJECTIVE

Previous studies have shown that e-cigarettes are perceived as being less harmful than tobacco cigarettes by pregnant women and might be used to quit smoking during pregnancy. Our aim was to further explore and characterise perceived threats, benefits and barriers of e-cigarette use during pregnancy.

METHODS

Our STudy on E-cigarettes and Pregnancy (STEP) was, among others, based on a netnographic approach of analysing existing threads in German-speaking online discussion forums dealing with perceived threats and benefits of e-cigarette use during pregnancy. For the analysis, we used an inductive-deductive qualitative content analysis.

FINDINGS

Based on 25 online discussion threads containing 1552 posts, we identified perceived threats, perceived benefits and perceived barriers to e-cigarette use during pregnancy, among others, as main themes. Subthemes identified within the main theme perceived threats were severe nicotine related health risks, potential health risks of additional ingredients, relative risks and lack of knowledge and research studies. As perceived benefits, we identified possibility and facilitation of smoking cessation, harm reduction and financial benefits. Perceived barriers were lack of satisfaction and social stigma.

CONCLUSION

Our qualitative results suggest that the perception of the health threats related to e-cigarette use during pregnancy varies according to the nicotine content and the perception of relative risks compared with tobacco cigarettes. In addition to this, risk perception is defined through further health and non-health related barriers and benefits (e.g. suitability of e-cigarettes as a smoking cessation aid, social stigma).

Association between mental health service utilisation and sharing of injection material among people who inject drugs in Montreal, Canada

BACKGROUND

High-risk injection behaviors are associated with high prevalence of mental health problems among people who inject drugs (PWID). However, whether the use of mental health services is associated with lower risk of sharing injection material remains undetermined. This study aims to examine the association between mental health service utilisation and receptive sharing risk, and determine the potential modifying effect of psychological distress on this association.

METHODS

Participants answered an interviewer-administered questionnaire at 3-month intervals gathering information on sociodemographic characteristics, substance use and related behaviors, services utilisation and significant mental health markers. Relationship between the use of mental health services and receptive sharing was modeled using the generalized estimating equation (GEE), controlling for age at baseline, gender, and other potential confounders. Psychological distress was estimated using the Kessler Psychological Distress Scale (K10). Effect modification was investigated by adding an interaction term in the univariate GEE analysis.

RESULTS

358 participants contributed to 2537 visits (median age 40.3, 82% male). Mental health service utilisation was reported in 631 visits (25%), receptive sharing in 321 visits (13%) and severe psychological distress in 359 visits (14%). In multivariate GEE analyses, a significant association was identified between receptive sharing and the use of mental health services (aOR = 0.69; 95% CI = 0.50-0.94). We found no evidence of effect modification by psychological distress.

CONCLUSION

Among PWID, mental health service utilisation was associated with lower likelihood of receptive sharing, regardless of level of psychological distress. These findings should be taken into account when designing harm reduction strategies for this population.

Re-Configuring Identity Postpartum and Sustained Abstinence or Relapse to Tobacco Smoking

Relapse to smoking postpartum is a common and important public health problem. Difficulty in adjusting to a non-smoking identity is a key factor prompting relapse. However, postpartum relapse prevention interventions rarely focus upon offering support for identity change. We conducted an exploratory inductive analysis of a dataset from the Prevention of Return to Smoking Postpartum (PReS) study to understand identity constructs and experiences of pre- and postpartum women (smokers and ex-smokers), partners and health professionals. Data were obtained from 77 unique participants via focus groups, interviews, email or online questionnaires, and were analyzed by two researchers independently, using NVivo 12. Four main themes emerged reflecting identity transition from the pre- to the postpartum period: (i) Pregnancy and the categorization of smoking status; (ii) the disruption of motherhood and loss of self; (iii) adapting to a maternal non-smoking identity; and (iv) factors influencing sustained abstinence versus relapse to smoking. Postpartum relapse prevention interventions need to consider support for women, and the whole family unit, in adjusting to a new identity as a non-smoking mother. Smoking status should be revisited throughout pregnancy and into the postpartum period to aid the long-term integration of smoke-free behavior.

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.

Long-term effects of a preconception lifestyle intervention on cardiometabolic health of overweight and obese women

Background

The global prevalence of obesity in women keeps increasing. The preconception period may be a window of opportunity to improve lifestyle, reduce obesity and improve cardiometabolic health. This study assessed the effect of a preconception lifestyle intervention on long-term cardiometabolic health in two randomized controlled trials (RCTs).

Methods

Participants of the LIFEstyle and RADIEL preconception lifestyle intervention studies with a baseline body mass index (BMI) ≥29 kg/m² were eligible for this follow-up study. Both studies randomized between a lifestyle intervention targeting physical activity, diet and behaviour modification or usual care. We assessed cardiometabolic health 6 years after randomization.

Results

In the LIFEstyle study (n = 111) and RADIEL study (n = 39), no statistically significant differences between the intervention and control groups were found for body composition, blood pressure, arterial stiffness, fasting glucose, homeostasis model assessment of insulin resistance, HbA1c, lipids and high sensitive C-reactive protein levels 6 years after randomization. Participants of the LIFEstyle study who successfully lost ≥5% bodyweight or reached a BMI <29 kg/m² during the intervention (n = 22, [44%]) had lower weight (−8.1 kg; 99% CI [−16.6 to −0.9]), BMI (−3.3 kg/m²; [−6.5 to −0.8]), waist circumference (−8.2 cm; [−15.3 to −1.3]), fasting glucose (−0.5 mmol/L; [−1.1 to −0.0]), HbA1c (−4.1 mmol/mol; [−9.1 to −0.8]), and higher HDL-C (0.3 mmol/L; [0.1–0.5]) compared with controls.

Conclusion

We found no evidence of improved cardiometabolic health 6 years after a preconception lifestyle intervention among overweight and obese women in two RCTs. Women who successfully lost weight during the intervention had better cardiometabolic health 6 years later, emphasizing the potential of successful preconception lifestyle improvement.

Perceived barriers to quitting cigarettes among hospitalized smokers with substance use disorders: A mixed methods study

AIMS

Smoking cessation may promote long-term recovery in patients with substance use disorders (SUD). Yet smoking rates remain alarmingly high in this population. Using a sequential explanatory mixed methods approach, we examined smoking rates among hospitalized patients with SUD at a large safety-net hospital, and then characterized factors associated with smoking behaviors both quantitatively and qualitatively.

METHOD

We abstracted data from all hospital admissions (7/2016-6/2017) and determined demographics, substance use type, and other characteristics associated with cigarette use among those with SUD. We then conducted semi-structured qualitative interviews with 20 hospitalized SUD smokers. We analyzed transcripts to characterize factors that affect patients' smoking habits, focusing on the constructs of the Health Belief Model.

RESULTS

The prevalence of cigarette smoking among hospitalized smokers with SUD was three times higher than those without SUD. Qualitative analyses showed that patients perceived that smoking cigarettes was a less serious concern than other substances. Some patients feared that quitting cigarettes could negatively impact their recovery and perceived that clinicians do not prioritize treating tobacco dependence. Almost all patients with heroin use disorder described how cigarette use potentiated their heroin high. Many SUD patients are turning to vaping and e-cigarettes to quit smoking.

CONCLUSION

Hospitalized patients with SUD have disproportionately high smoking rates and perceive multiple barriers to quitting cigarettes. When designing and implementing smoking cessation interventions for hospitalized patients with SUD, policymakers should understand and take into account how patients with SUD perceive smoking-related health risks and how that influences their decision to quit smoking.

The relationship between health-related variables and increases in smoking among recently diagnosed HIV+ people who inject drugs in Vietnam

BACKGROUND

In Vietnam tobacco smoking is prevalent among people living with HIV (PLHIV) and causes excess mortality in this population. Injection drug use is a driver of HIV infections in Vietnam. Changes in HIV disease state may correlate to changes in smoking among PLHIV. This study investigates the relationship between increases in smoking and health-related variables among recently diagnosed HIV+ people who inject drugs (PWID) in Vietnam.

METHODS

We analyzed longitudinal data from 323 recently diagnosed HIV+ PWID in a randomized controlled trial from 2009 to 2013 in Thai Nguyen province, Vietnam. The outcome was an increase of >one cigarette/day from baseline visit cigarette smoking. A generalized estimating equation for repeated measures was used to estimate bivariable and multivariable associations between participant characteristics and smoking increases. We collected qualitative data to enhance our understanding of quantitative results, from 16 HIV+ PWID who smoke.

RESULTS

Ninety three point 5% of participants reported some smoking at baseline. Smoking fewer cigarettes, higher health related quality of life (QOL), and higher CD4 counts were predictive of increases in smoking at future visits in a multivariable model. Qualitative data showed smoking increases were tied to improved perceived health, and counseling during respiratory illnesses may increase intention to quit.

CONCLUSION

HIV+ PWID in Vietnam smoke at a very high rate. Increases in their smoking are correlated to increases in heath-related QOL, and increases in perceptions of health. Any tobacco-use intervention should account for internal tobacco use triggers faced by HIV+ PWID.

A mixed methods process evaluation of a print-based intervention supported by internet tools to improve physical activity in UK cancer survivors

OBJECTIVE

A waiting list randomised control trial has shown the Move More Pack, a print-based intervention supported by Internet tools, to improve physical activity levels in cancer survivors; however, one-third of them do not improve from the intervention. The objective of this process evaluation is to understand intervention use, the mechanisms of impact, the perceived benefits and the contextual factors influencing these, identifying for whom it is a useful resource.

METHODS

The process evaluation used mixed methods, based on guidance from the UK Medical Research Council, including 181 questionnaire responses on intervention use and physical activity improvement over 12 weeks, 56 open-text responses and 17 semistructured interviews.

RESULTS

The Move More Pack was suggested to be most useful when delivered towards the start of the cancer journey to those with a positive attitude to fight cancer but with a low level of physical activity, capitalising on a teachable moment. It was suggested that healthcare professionals could support the effective distribution of the Move More Pack. The intervention's printed components were more popular and well used than the Internet tools. Use of the printed intervention components was positively correlated with physical activity improvement but use of the Internet tools was not. Women were more likely to use the intervention's printed components than men. Cancer survivors using the intervention reflected that they had increased confidence and motivation for physical activity and other lifestyle behaviours.

CONCLUSION

The Move More Pack should be offered by healthcare professionals, during cancer treatment, when health is salient, to those with a positive attitude to fight cancer but with low levels of physical activity. Use of the intervention's printed components is more likely to improve physical activity than the Internet tools, and the components are more likely to be used by women. The use of Internet tools to support physical activity improvement in cancer survivors requires further investigation.
