Lifetime parental smoking history and cessation and early adolescent smoking behavior

The associations of parental smoking, quitting and habitus with teenager e-cigarette, smoking, alcohol and other drug use in GUI Cohort '98

We analyse parental smoking and cessation (quitting) associations with teenager e-cigarette, alcohol, tobacco smoking and other drug use, and explore parental smoking as a mechanism for social reproduction. We use data from Waves 1-3 of Growing Up in Ireland (Cohort '98). Our analytic sample consisted of n = 6,039 participants reporting in all 3 Waves. Data were collected in Waves 1 and 2 when the children were 9 and 13 years old and in Wave 3 at age 17/18 years. Generalized Estimating Equations (GEE) models were used to analyse teenage substance use at Wave 3. Parental smoking was associated with significantly increased risk of all teenage substance use, adjusted odds ratios were aOR2.13 (ever e-cigarette use); aOR1.92 (ever alcohol use); aOR1.88 (current alcohol use); aOR1.90 (ever use of other drugs); aOR2.10 (ever-smoking); and aOR1.91 (current smoking). Primary caregiver smoking cessation (quitting) was associated with a lower risk for teenager current smoking aOR0.62, ever e-cigarette use aOR 0.65 and other drug use aOR 0.57. Primary caregiver smoking behaviour had greater associations than secondary, and age13 exposure more than age 9. Habitus seems to play a role and wealth was protective for teenage smoking. The findings suggest that prevention interventions should target both caregivers and their children.

Association between the second- and fourth-digit ratio and oral squamous cell carcinoma

OBJECTIVES

Using an established proxy measure of intra-utero testosterone and estrogen levels-the ratio of second- and fourth-digit lengths-we estimated its association with the oral cancer risk among a population from Southern India.

MATERIAL AND METHODS

In a hospital-based case-control study, incident oral cancer cases (N = 350) and non-cancer controls (N = 371), frequency-matched by age and sex, were recruited from two major referral hospitals in Kerala, India. Structured interviews collected information on several domains of exposure via detailed life course questionnaires. Digit lengths were measured using a ruler in a standardized manner. Unconditional logistic regression was performed to estimate the odds ratios and 95% confidence intervals.

RESULTS

Second- and fourth-digit ratio lower than 1, which indicates relatively higher intra-utero level of testosterone and lower intra-utero level of estrogen, was associated with higher oral cancer risk (OR = 1.60, 95% CI: 1.02-2.52), after accounting for several confounders.

CONCLUSION

Our findings suggest that intra-utero hormonal levels measured by second- and fourth-digit ratio are associated with oral cancer risk. Further studies in different population should confirm these results.

A Clinical Decision Support System for Motivational Messaging and Tobacco Cessation Treatment for Parents: Pilot Evaluation of Use and Acceptance

BACKGROUND

Research is needed to identify how clinical decision support (CDS) systems can support communication about and engagement with tobacco use treatment in pediatric settings for parents who smoke. We developed a CDS system that identifies parents who smoke, delivers motivational messages to start treatment, connects parents to treatment, and supports pediatrician-parent discussion.

OBJECTIVE

The objective of this study is to assess the performance of this system in clinical practice, including receipt of motivational messages and tobacco use treatment acceptance rates.

METHODS

The system was evaluated at one large pediatric practice through a single-arm pilot study from June to November 2021. We collected data on the performance of the CDS system for all parents. Additionally, we surveyed a sample of parents immediately after the clinical encounter who used the system and reported smoking. Measures were: (1) the parent remembered the motivational message, (2) the pediatrician reinforced the message, and (3) treatment acceptance rates. Treatments included nicotine replacement therapy, quitline referral (phone counseling), and/or SmokefreeTXT referral (text message counseling). We described survey response rates overall and with 95% confidence intervals (CIs).

RESULTS

During the entire study period, 8,488 parents completed use of the CDS: 9.3% (n = 786) reported smoking and 48.2% (n = 379) accepted at least one treatment. A total of 102 parents who smoke who used the system were approached to survey 100 parents (98% response rate). Most parents self-identified as female (84%), aged 25 to 34 years (56%), and Black/African American (94%), and had children with Medicaid insurance (95%). Of parents surveyed, 54% accepted at least one treatment option. Most parents recalled the motivational message (79%; 95% CI: 71-87%), and 31% (95% CI: 19-44%) reported that the pediatrician reinforced the motivational message.

CONCLUSION

A CDS system to support parental tobacco use treatment in pediatric primary care enhanced motivational messaging about smoking cessation and evidence-based treatment initiation.

Cross-talks between gut microbiota and tobacco smoking: a two-sample Mendelian randomization study

BACKGROUND

Considerable evidence has been reported that tobacco use could cause alterations in gut microbiota composition. The microbiota-gut-brain axis also in turn hinted at a possible contribution of the gut microbiota to smoking. However, population-level studies with a higher evidence level for causality are lacking.

METHODS

This study utilized the summary-level data of respective genome-wide association study (GWAS) for 211 gut microbial taxa and five smoking phenotypes to reveal the causal association between the gut microbiota and tobacco smoking. Two-sample bidirectional Mendelian randomization (MR) design was deployed and comprehensively sensitive analyses were followed to validate the robustness of results. We further performed multivariable MR to evaluate the effect of neurotransmitter-associated metabolites on observed associations.

RESULTS

Our univariable MR results confirmed the effects of smoking on three taxa (Intestinimonas, Catenibacterium, and Ruminococcaceae, observed from previous studies) with boosted evidence level and identified another 13 taxa which may be causally affected by tobacco smoking. As for the other direction, we revealed that smoking behaviors could be potential consequence of specific taxa abundance. Combining with existing observational evidence, we provided novel insights regarding a positive feedback loop of smoking through Actinobacteria and indicated a potential mechanism for the link between parental smoking and early smoking initiation of their children driven by Bifidobacterium. The multivariable MR results suggested that neurotransmitter-associated metabolites (tryptophan and tyrosine, also supported by previous studies) probably played a role in the action pathway from the gut microbiota to smoking, especially for Actinobacteria and Peptococcus.

CONCLUSIONS

In summary, the current study suggested the role of the specific gut microbes on the risk for cigarette smoking (likely involving alterations in metabolites) and in turn smoking on specific gut microbes. Our findings highlighted the hazards of tobacco use for gut flora dysbiosis and shed light on the potential role of specific gut microbiota for smoking behaviors.

A content analysis of 'junk food' content in children's TV programmes: a comparison of UK broadcast TV and video-on-demand services

OBJECTIVES

Exposure to high in fat, sugar or salt (HFSS) food imagery is associated with unhealthy consumption, and subsequently obesity, among young people. We report and compare the results of two content analyses, one of popular children's television channels in the UK and the other of a selection of children's programmes available on video-on-demand (VOD) services.

METHODS

Content analysis of 3 days' worth of programmes on two popular children's television channels broadcast on UK television (CBeebies and Milkshake as well as a sample of children's programmes available on the VOD platforms (Netflix and Amazon Prime) using 1-min interval coding.

RESULTS

In children's television channels, HFSS content was seen in 181 episodes (36%) and in 417 intervals (13%) on terrestrial television, 'Milkshake' had a significantly higher proportion of broadcasts, which contained HFSS content than 'CBeebies'. In VOD platforms, HFSS content was seen in 82 episodes (72% of the total number of episodes), across 459 intervals (19% of the total number of intervals), with no significant difference in the proportion of programmes containing HFSS content between Netflix and Amazon Prime.

CONCLUSIONS

HFSS content is common in both popular UK children's television channels and children programmes on VOD services and is likely having an effect on HFSS consumption in children. Legislative opportunities to prevent this exposure are being missed.

Electronic Health Record-Embedded, Behavioral Science-Informed System for Smoking Cessation for the Parents of Pediatric Patients

BACKGROUND

 Helping parents quit smoking is a public health priority. However, parents are rarely, if ever, offered tobacco use treatment through pediatric settings. Clinical decision support (CDS) systems developed for the workflows of pediatric primary care may support consistent screening, treatment, and referral.

OBJECTIVES

 This study aimed to develop a CDS system by using human-centered design (HCD) that identifies parents who smoke, provides motivational messages to quit smoking (informed by behavioral science), and supports delivery of evidence-based tobacco treatment.

METHODS

 Our multidisciplinary team applied a rigorous HCD process involving analysis of the work environment, user involvement in formative design, iterative improvements, and evaluation of the system's use in context with the following three cohorts: (1) parents who smoke, (2) pediatric clinicians, and (3) clinic staff. Participants from each cohort were presented with scenario-based, high-fidelity mockups of system components and then provided input related to their role in using the CDS system.

RESULTS

 We engaged 70 representative participants including 30 parents, 30 clinicians, and 10 clinic staff. A key theme of the design review sessions across all cohorts was the need to automate functions of the system. Parents emphasized a system that presented information in a simple way, highlighted benefits of quitting smoking, and allowed direct connection to treatment. Pediatric clinicians emphasized automating tobacco treatment. Clinical staff emphasized screening for parent smoking via several modalities prior to the patient's visit. Once the system was developed, most parents (80%) reported that it was easy to use, and the majority of pediatricians reported that they would use the system (97%) and were satisfied with it (97%).

CONCLUSION

 A CDS system to support parental tobacco cessation in pediatric primary care, developed through an HCD process, proved easy to use and acceptable to parents, clinicians, and office staff. This preliminary work justifies evaluating the impact of the system on helping parents quit smoking.

Erciyes Üniversitesi Öğrencilerinde Sigara İçme Durumunun 1985 – 2019 Yılları Arasındaki Değişimi

Amaç: Bu çalışmada Erciyes Üniversitesi öğrencileri arasında sigara kullanım durumu ile nikotin bağımlığı düzeyini saptamak ve elde edilen verilerin ilgili bölüm ve araştırmacılar tarafından 1985 ve 2005 yıllarında yapılan önceki çalışmalarla karşılaştırarak, tütün kullanma durumundaki değişimi değerlendirmek amaçlanmıştır. Yöntem: Bu kesitsel Araştırma 2018-2019 eğitim döneminde, Erciyes Üniversitesi Tıp, Mühendislik ve İlahiyat fakültelerinde okuyan öğrenciler üzerinde yapıldı. Örneklem büyüklüğü 1500 kişi olarak hesaplandı. Veri toplama aracı olarak, araştırmacılar tarafından hazırlanan ve 48 sorudan oluşan anket formu ve altı sorudan oluşan Fagerström Nikotin Bağımlılık Testi (FNBT) kullanıldı. Bulgular: Çalışma 1348 öğrenci ile tamamlandı. Sigara kullanım oranı kadınlarda %6.3 ve erkeklerde %28.0 ve toplamda %16.1 olarak bulundu. Bölümlere göre en yüksek sigara içme oranı %25.9 ile mühendislik fakültesinde görüldü. Tıp fakültesi ve ilahiyat fakültelerinde sigara içme oranları sırasıyla %13.9 ve %5.0 olarak bulundu. Erkeklerde nikotin bağımlılık düzeyi yüksek ve çok yüksek olanların oranı %17.6 ile kadınların %6.4’lük oranından anlamlı olarak daha yüksekti (p=0,027). Toplam FNBT puan ortalaması 3.06±2.32 idi. Genel anlamda sigara kullanım sıklığı değerlendirildiğinde; 1985 yılında % 29.8 (E: 33.90, K: 12.20) ve 2005 yılında % 16.7 (E: 25.60, K:5.10) iken, 2019 yılına gelindiğinde % 16.1 (E: 28.0, K:6.3) olmuştur. Sonuç: Erciyes Üniversitesi öğrencilerinde sigara kullanım oranı öğrenci profilinin değişimine bağlı olarak etkilenmektedir. Her ne kadar alınan önlemler ile bir dönem sigara kullanımı düşmüş olsa da 2019 yılında, cinsiyet bazında; hem kadın, hem de erkeklerde sigara içme oranında bir yükselme olduğu söylenebilirken genel kullanım oranında ise düşüş görülmektedir.

Factors associated with the onset of smoking and alcohol consumption: A cross-sectional study among Lebanese adolescents in schools

OBJECTIVES

This study aimed to evaluate factors and profiles associated with the earlier onset of cigarette/waterpipe smoking and alcohol consumption among Lebanese adolescents in schools.

METHODS

A total of 4000 adolescents (mean age = 15.31 ± 2.01 years) participated in this cross-sectional study. The standardized questionnaire was taken from the Health Behavior in School Children (HBSC) study in different countries (France, Belgium, and the USA) and adjusted to the Lebanese population. K-means clustering analysis was conducted to classify participants into three clusters according to their patterns (surrounded by smokers, surrounded by drinkers, and ease of talking to family members and friends) and Cox regression analyzes were conducted.

RESULTS

Participants were divided into three clusters. Cluster 1 (16.75% of participants) included adolescents with the lowest ease of talking to a family member or friend, with the latter smoking and drinking a lot (worst cluster). Cluster 2 (54.95%) included adolescents with moderate ease of talking to a family member and more to friends, surrounded by low-to-moderate smoking and alcohol consumption, particularly for a best friend (positive influence cluster). Finally, cluster 3 (28.30%) included adolescents with low ease of talking to friends, moderate ease of talking to a family member, and low-to-moderate smoking and alcohol consumption (low influence cluster). The results of the Cox regressions (taking the age at onset of smoking cigarettes and waterpipes as the dependent variables) showed that older age at onset of cigarette and waterpipe smoking was significantly associated with female participants and those belonging to clusters 2 and 3 compared to cluster 1. Moreover, a younger age at first alcohol use and getting drunk was significantly associated with living outside Beirut, whereas female gender and belonging to clusters 2 or 3 compared to cluster 1 were significantly associated with older age at first alcohol use and getting drunk.

CONCLUSION

This study identified risk factors (ease of talking as well as smoking and alcohol-drinking status of parents, siblings, and friends) and profiles related to early alcohol and cigarette/waterpipe use. These risk factors and profiles could help implement prevention campaigns to reduce substance use and improve adolescent health.

The Utilization of National Tobacco Cessation Services among Female Smokers and the Need for a Gender-Responsive Approach

Despite the steadily increasing prevalence of female smoking, gender-responsive tobacco cessation services have not been widely provided worldwide. The purpose of this study is to identify factors associated with the use of tobacco cessation services among female tobacco product users in Korea from a national perspective. We performed a logistic regression analysis using data from 663 female smokers; 11.0% of female smokers had used government-supported smoking cessation services. A logistic regression model showed a statistically significant association between the utilization of smoking cessation services and a history of pregnancy and childbirth, depression, current use of heated tobacco products and multiple tobacco products, parental smoking status and receiving advice to quit. With regard to the motivation ruler, those in their 50s reported a higher importance than those in their 20s. Weight gain concerns when quitting smoking were the lowest among the participants aged 19-29. The need to develop gender-specific smoking cessation programs is the highest among the participants aged 39-49 and the lowest among those aged 19-29. This study suggests several factors related to the utilization of national health services among female smokers. Further studies considering gender-specific needs for the development of gender-responsive tobacco cessation support are needed.

Spontaneous Smoking Cessation in Parents

Purpose

To determine the percentage of parents who report quitting spontaneously and examine the factors associated with these quits.

Methods

As part of a cluster randomized control trial addressing parental smoking in a pediatric outpatient setting, 12-month follow-up survey data were collected from parents who had self-identified as smokers when exiting from 10 control practices. Parents were considered to have made a spontaneous quit if they reported not smoking a cigarette, even a puff, in the last 7 days and chose the statement "I did not plan the quit in advance; I just did it" when describing how their quit attempt started.

Results

Of the 981 smoking parents enrolled at baseline, 710 (72%) completed the 12-month follow-up. Of these, 123 (17%) reported quitting, of whom 50 (41%) reported quitting spontaneously. In multivariable analysis, parents who reported smoking on some days vs. every day (OR 3.06 (95% CI 1.42, 6.62)) and that nobody had smoked in their home/car vs. someone had smoked in these settings in the past 3 months (OR 2.19 (95% CI 1.06, 4.54)) were more likely to quit spontaneously.

Conclusions

This study shows that, of parents who quit smoking, a substantial percentage report quitting spontaneously and that intermittent smoking and smoke-free home/car policies are associated with reports of quitting spontaneously. Promoting smoke-free home/car policies, especially when parents are not willing to make a plan to quit smoking, might increase the likelihood that parents decide to quit without advance planning. Pediatric healthcare providers are uniquely positioned to use the child's visit to motivate parents to quit smoking and eliminate their child's exposure to tobacco smoke, regardless of the frequency of smoking or a readiness to plan a quit attempt.

Engaging People in Tobacco Prevention and Cessation: Reflecting Back Over 20 Years Since the Master Settlement Agreement

Over the past 20 years, tobacco prevention and cessation efforts have evolved to keep pace with the changing tobacco product landscape and the widespread adoption of digital technologies. In 2019, Truth Initiative was awarded the Society of Behavioral Medicine’s Jessie Gruman Award for Health Engagement in recognition of the major role it has played on both fronts since its inception in 1999. This manuscript reviews the challenges and opportunities that have emerged over the past two decades, the evolving tactics deployed by Truth Initiative to engage people in tobacco prevention and cessation efforts, the approaches used to evaluate those efforts, and key achievements. It concludes with a summary of lessons learned and considerations for tobacco control researchers and practitioners to accelerate their impact on public health.

Pediatrician Delivered Smoking Cessation Messages for Parents: A Latent Class Approach to Behavioral Phenotyping

OBJECTIVE

Message framing can be leveraged to motivate adult smokers to quit, but its value for parents in pediatric settings is unknown. Understanding parents' preferences for smoking cessation messages may help clinicians tailor interventions to increase quitting.

METHODS

We conducted a discrete choice experiment in which parent smokers of pediatric patients rated the relative importance of 26 messages designed to increase smoking cessation treatment. Messages varied on who the message featured (child, parent, and family), whether the message was gain- or loss-framed (emphasizing benefits of engaging or costs of failing to engage in treatment), and the specific outcome included (eg, general health, cancer, respiratory illnesses, and financial impact). Participants included 180 parent smokers at 4 pediatric primary care sites. We used latent class analysis of message ratings to identify groups of parents with similar preferences. Multinomial logistic regression described child and parent characteristics associated with group membership.

RESULTS

We identified 3 groups of parents with similar preferences for messages: Group 1 prioritized the impact of smoking on the child (n = 92, 51%), Group 2 favored gain-framed messages (n = 63, 35%), and Group 3 preferred messages emphasizing the financial impact of smoking (n = 25, 14%). Parents in Group 2 were more likely to have limited health literacy and have a child over age 6 and with asthma, compared to Group 1.

CONCLUSIONS

We identified 3 groups of parent smokers with different message preferences. This work may inform testing of tailored smoking cessation messages to different parent groups, a form of behavioral phenotyping supporting motivational precision medicine.

Innovations in parental smoking cessation assistance delivered in the child healthcare setting

Addressing parental smoking in the child healthcare setting improves the health of all family members. Innovative approaches, such as mobilizing technology-based platforms, may streamline screening and motivate acceptance of behavioral health services to treat tobacco use and dependence. The obective of this study was to describe innovations added to the CEASE intervention and to track 2 year post-intervention implementation data on families who were screened for tobacco use. Child healthcare practices in five states (IN, NC, OH, TN, and VA) used an electronic tablet screener to identify tobacco use within families and deliver tobacco cessation assistance to smokers. Motivational/educational videos on cessation were displayed via the screener to enhance its utility. Five CEASE intervention practices screened 50,111 family members for tobacco use and identified 6,885 families with children exposed to tobacco smoke. The mean number of screeners per practice per month was 417; the mean number of households with smokers identified per month was 57. Of 2,764 smokers who were at visits and consented, 57% indicated that they wanted a prescription to reduce or quit smoking; 94% of these were given preprinted prescriptions. Of 41% who requested connection to the quitline, 93% were given enrollment forms. Electronic screening was used to routinely identify tobacco users, leading to increased potential for offering cessation assistance to all household members who smoke. Improved delivery of smoking cessation services to families may be achieved by integrating technological innovations into routine pediatric practice.

Parent Preferences for Pediatric Clinician Messaging to Promote Smoking Cessation Treatment

BACKGROUND AND OBJECTIVES

Insights from behavioral economics suggests that the effectiveness of health messages depends on how a message is framed. Parent preferences for smoking cessation messaging has not been studied in pediatrics, warranting further exploration to maximize benefit. We sought to assess parents' perceptions regarding the relative importance of distinct message framings to promote their smoking cessation.

METHODS

We conducted a cross-sectional discrete choice experiment in which parent smokers rated the relative importance of 26 messages designed to encourage them to begin cessation treatment. Messages varied on who was featured (child, parent, or family), whether the message was gain or loss framed, and what outcome was included (general health, cancer, respiratory illnesses, child becoming a smoker, or financial impact). The participants were 180 parent smokers attending primary care visits with their children at 4 diverse pediatric sites. The main outcome was the importance of smoking cessation messages based on who was featured, gain or loss framing, and the outcome emphasized.

RESULTS

Parent smokers highly prioritized cessation messages emphasizing the impact of quitting smoking on their child versus parent or family. Messages focusing on respiratory illness, cancer, or general health outcomes consistently ranked highest, whereas messages focused on the financial benefits of quitting ranked lowest. Gain versus loss framing did not meaningfully influence rankings.

CONCLUSIONS

Parent smokers identified smoking cessation messages that emphasized the impact on their child, with outcomes focused on respiratory health, cancer, or general health, as most important. The clinical impact of these messages should be tested in future research.

Joint Effects of Parental Smoking Cessation and an Antismoking Parenting Program on Children's Susceptibility to Smoking: A Three-Year Prospective Study

Cognitive susceptibility to smoking is indicated by positive social expectancies about smoking, being curious about smoking, wanting to try smoking, and intending to try smoking. Among children, cognitive susceptibility is a risk factor for initiating smoking; reducing susceptibility is, therefore, a viable primary prevention strategy. Our study tested prospectively the combined effect of two variables-parental modeling of smoking cessation and parental exposure to an antismoking parenting program-on cognitive susceptibility to smoking among children who had never puffed on a cigarette. The study sample comprised 859 daily smokers who called a state Quitline seeking assistance to quit smoking and these adults' 8- to 10-year-old children. The factors in the 2 × 2 design were parental modeling of cessation (successful cessation vs. continued smoking) and parental exposure to an antismoking parenting program (program vs. control). We hypothesized that children whose parents both quit smoking and received the antismoking parenting program would report lower susceptibility to smoking than children exposed to one or neither of these factors. Multivariable analysis of variance, conducted using child-reported susceptibility to smoking collected 12, 24, and 36 months post-baseline, confirmed this hypothesis. Post hoc tests for simple main effects showed that, at each time point, parent smoking cessation had a significant protective effect on children's susceptibility to smoking, but only among children whose parents received the parenting program. These tests also showed that the parenting program had a significant protective effect on children's susceptibility to smoking, but only among children whose parents had successfully quit smoking. Our study results suggest that Quitlines and other programs that assist adults in quitting smoking could extend the reach and benefits of such assistance by providing parents with resources that promote antismoking parenting practices.

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.

Parent eReferral to Tobacco Quitline: A Pragmatic Randomized Trial in Pediatric Primary Care

INTRODUCTION

Quitlines are effective in helping smokers quit, but pediatrician quitline referral rates are low, and few parents who smoke use the service. This study compared enrollment of parents who smoke in the quitline using electronic referral with that using manual referral.

STUDY DESIGN

The study was designed as a pragmatic RCT.

SETTING/PARTICIPANTS

Participants were recruited from one large, urban pediatric primary care site in Philadelphia, Pennsylvania with a high percentage of low-income families. Participants included adult parents who smoked and were present at their child's healthcare visit.

INTERVENTION

Pediatricians screened for tobacco use; smokers were given brief advice to quit and, if interested in quitting, were referred to the quitline. The eReferral ("warm handoff") involved electronically sending parent information to the quitline (parent received a call within 24-48 hours). Control group procedures were identical to eReferral, except the quitline number was provided to the parent. Data were collected between March 2017 and February 2018 and analyzed in 2018.

MAIN OUTCOME MEASURES

The primary outcome was the proportion of parents enrolled in quitline treatment. Secondary outcomes included parent factors (e.g., demographics, nicotine dependence, and quitting motivation) associated with successful enrollment. Number of quitline contacts was also explored.

RESULTS

During the study period, in the eReferral group, 10.3% (24 of 233) of parents who smoked and were interested in quitting enrolled in the quitline, whereas only 2.0% (5 of 251) of them in the control group enrolled in the quitline-a difference of 8.3% (95% CI=4.0, 12.6). Parents aged ≥50 years enrolled in the quitline more frequently. Although more parents in the eReferral group connected to the quitline, among parents who had at least one quitline contact, there was no significant difference in the mean number of quitline contacts between eReferral and control groups (mean, 2.04 vs 2.40 calls; difference, 0.36 [95% CI=0.35, 1.06]).

CONCLUSIONS

Smoking parent eReferral from pediatric primary care may increase quitline enrollment and could be adopted by practices interested in increasing rates of parent treatment.

How much and why does the mum matter? Mechanisms explaining the intergenerational transmission of smoking

Offspring whose mother smokes during pregnancy have higher risk of smoking themselves. In this study, epigenetics, antisocial behaviours, and social learning were investigated as potential mechanisms of mother-to-child transmission of smoking among a population sample drawn from the Birth Cohort Study 1970. Findings on daughters showed that the direct epigenetic hypothesis was mediated by social learning mechanisms, suggesting that exposure to maternal smoking across childhood and adolescence strongly explained why the smoking habits of mother and daughter correlate. However, prenatal smoking effects on sons were only partially explained by observational learning of mother smoking habits. Our estimates provided evidence concerning the potential role also played by the child's persistent antisocial behaviours. These results were confirmed after controlling for early life circumstances and current socioeconomic conditions. Policy implications of the results are discussed.

Parental Optimism About Children's Risk of Future Tobacco Use and Excessive Weight Gain

BACKGROUND

Adults tend to underestimate their personal risk of disease, but little is known about parents' perceptions of children's risk.

METHODS

In total, 648 parents of children 0 to 18 years old attending 2 pediatric practices were surveyed about their children's exposure to smoking; 344 parents with children ≥2 years old also were asked about their children's sugar-sweetened beverage (SSB) consumption and physical activity. Children were categorized as "at risk" or "not at risk" for each factor. Parents estimated the risk of their child becoming a smoker or gaining excessive weight and were categorized as "optimistic" if they believed their children were less likely than others to use tobacco or gain weight.

RESULTS

Overall, 92% of parents thought their children were at lower risk than average for tobacco use, and 86% believed their children were at lower risk for excessive weight gain. A high frequency of optimistic bias occurred even among parents with "at-risk" children, including parents with children exposed to tobacco use (70.4%), SSB consumption (77.6%), >2 hours of screen time (82.1%), and low physical activity (84.1%). In multivariable analyses, parents with children exposed to tobacco smoke (odds ratio = 0.21, 95% confidence interval, 0.09-0.51); or who consumed SSBs daily (odds ratio = 0.44, 95% confidence interval 0.20-0.97) were less likely to be optimistic about their child's future tobacco use and excessive weight gain, respectively.

CONCLUSIONS

Most parents believed their children were at lower risk than average for tobacco use or excessive weight gain. Eliciting parents' optimistic biases might facilitate behavior change counseling in pediatric settings.

The Influence of Partner Smoking, Relationship Satisfaction and Parental Stress on Tobacco Use

Introduction

Despite declines in tobacco use during pregnancy and after childbirth, smoking remains unacceptably high among many parents. Smoking maintenance or relapse may be common in couple relationships when the other parent continues to smoke, when relationship satisfaction is low, or parental stress high.

Aim

To examine the longitudinal influence of partner tobacco use, relationship satisfaction and parental stress on tobacco use after childbirth.

Methods

Data was obtained from 115 Australian heterosexual adult couples (Mean age = 31.8) who reported being pregnant in the previous year and the female partner was a previous or current smoker. A household longitudinal survey was administered in which measures of tobacco use, relationship satisfaction and parental stress were assessed on four occasions over nine years.

Results

Overall reductions in tobacco use occurred over the nine-year assessment period, although a small percentage (9.6%) of parents reported being daily smokers at every assessment. Similarly, a small proportion (13.1%) of parents relapsed to using tobacco during the assessment period. A random effects binary logit model indicated that mothers and fathers were more likely to continue or relapse to tobacco use if their partners smoked. Mothers were more likely to quit smoking if they became pregnant between the assessment waves, but for males, having a pregnant partner was not a significant predictor of tobacco cessation.

Conclusion

While pregnancy is associated with smoking cessation for mothers, both mothers and fathers are at elevated risk of continued tobacco smoking or relapse if their partner smokes during the first nine years after childbirth. For parents who continue to smoke cigarettes or relapse after childbirth, engagement of the partner in smoking cessation may be a key factor in promoting positive outcomes.

The effect of parental smoking on preadolescents' implicit and explicit perceptions of smoking-related cues

Children of smokers are significantly more likely to experiment with cigarettes and become habitual smokers than children of nonsmokers. The current study examined the effect of parental smoking on children's implicit and explicit responses toward smoking behavior and smoking-related cues with the goal of identifying potential mechanisms for this relationship. A sample of 8-12-year-old children of smokers (n = 57) and children of nonsmokers (n = 86) completed a dot probe task to assess implicit attentional bias toward smoking cues and the Affect Misattribution Procedure (AMP) to assess implicit affective responses to smoking cues. In addition, children indicated their explicit perceptions of smokers and smoking behavior. Results demonstrated that children of smokers showed more sustained implicit attentional bias toward pictures of smoking stimuli presented alone than children of nonsmokers. Overall, participants showed negative implicit affective responses to smoking stimuli regardless of parental smoking. Children of smokers indicated that smokers would experience fewer negative consequences than children of nonsmokers; these relationships were moderated by age. Together, our findings suggest that parental smoking affects the ways that preadolescent children implicitly process smoking cues and their perceptions about smoking and its consequences. These findings help us understand the environmental mechanisms associated with smoking behavior in this vulnerable population. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Cross-Cultural Comparison of Genetic and Cultural Transmission of Smoking Initiation Using an Extended Twin Kinship Model

BACKGROUND

Considerable evidence from twin and adoption studies indicates that genetic and shared environmental factors play a role in the initiation of smoking behavior. Although twin and adoption designs are powerful to detect genetic and environmental influences, they do not provide information on the processes of assortative mating and parent-offspring transmission and their contribution to the variability explained by genetic and/or environmental factors.

METHODS

We examined the role of genetic and environmental factors in individual differences for smoking initiation (SI) using an extended kinship design. This design allows the simultaneous testing of additive and non-additive genetic, shared and individual-specific environmental factors, as well as sex differences in the expression of genes and environment in the presence of assortative mating and combined genetic and cultural transmission, while also estimating the regression of the prevalence of SI on age. A dichotomous lifetime 'ever' smoking measure was obtained from twins and relatives in the 'Virginia 30,000' sample and the 'Australian 25,000'.

RESULTS

Results demonstrate that both genetic and environmental factors play a significant role in the liability to SI. Major influences on individual differences appeared to be additive genetic and unique environmental effects, with smaller contributions from assortative mating, shared sibling environment, twin environment, cultural transmission, and resulting genotype-environment covariance. Age regression of the prevalence of SI was significant. The finding of negative cultural transmission without dominance led us to investigate more closely two possible mechanisms for the lower parent-offspring correlations compared to the sibling and DZ twin correlations in subsets of the data: (1) age × gene interaction, and (2) social homogamy. Neither of the mechanism provided a significantly better explanation of the data.

CONCLUSIONS

This study showed significant heritability, partly due to assortment, and significant effects of primarily non-parental shared environment on liability to SI.

The role of parental smoking on adolescent smoking and its social patterning: a cross-sectional survey in six European cities

Background

Several studies have observed socio-economic (SE) inequalities in smoking among adolescents, but its causes are not fully understood. This study investigates the association between parental and adolescent smoking, and whether this association is socially patterned.

Methods

We used data from a survey administered in 2013 to students aged 14-17 years old of six European cities (n = 10 526). Using multilevel mixed-effects logistic regression, we modelled the probability of being a daily smoker as a function of parental smoking and SE status. We tested whether the smoking association differed across social strata.

Results

The prevalence of parental smoking was higher in low SE status adolescents. Boys and girls were more likely to smoke if they have a father [boys: adjusted odds ratio (AOR) = 1.90, 95% CI = 1.47-2.46; girls: AOR = 1.42, 95% CI = 1.09-1.86] and mother (boys: AOR = 1.77, 95% CI = 1.35-2.31; girls: AOR = 3.36, 95% CI = 2.56-4.40) who smoked. Among boys, the odds of smoking when having a smoking parent were higher in lower SE classes. However, this was not statistically significant, nor was it observed among girls.

Conclusions

Adolescents are more likely to smoke when their father and mother smoke. Although the susceptibility to parental smoking was similar across social classes, SE differences in parental smoking contribute to the transmission of SE inequalities in smoking.

Adult Attitudes and Practices Regarding Smoking Restrictions and Child Tobacco Smoke Exposure: 2000 to 2015

BACKGROUND AND OBJECTIVES

Since 2000, tobacco control efforts have greatly increased state and local protections from childhood tobacco smoke exposure. The objective of this study is to examine changes in attitudes and practices regarding smoking bans in multiple public and private settings from 2000 to 2015, as well as to examine the changes in pediatrician and family practitioner screening and counseling for tobacco smoke exposure.

METHODS

Cross-sectional data from the annual Social Climate Survey of Tobacco Control were analyzed.

RESULTS

The majority of adults, 69.3%, reported household smoking restrictions in 2000, and these restrictions increased to 79.5% through 2015 (P < .05). Car smoking prohibitions increased from 68.3% to 81.8% (P < .05). A growing majority of adults supports smoke-free policies in public settings, and tobacco counseling by child health care providers also increased. However, members of 1 in 5 households still permit smoking inside the home and family vehicle, and half of the US population is not protected by state or local laws prohibiting smoking inside of hospitality venues.

CONCLUSIONS

Despite dramatic progress since 2000, these trend data reveal potential areas where child health care clinicians might focus effort at the family and community level to accelerate the protection of children from tobacco smoke exposure.

The longitudinal, bidirectional relationships between parent reports of child secondhand smoke exposure and child smoking trajectories

This study examines the longitudinal relationships between child smoking and secondhand smoke exposure (SHSe). Participants were 222 parent-child dyads. The parents smoked, had a child with (48%) or without asthma, and were enrolled in a smoking/health intervention. Parent-reported child SHSe was measured at baseline and 4, 6, and 12-month follow-ups; self-reported child smoking was assessed at these points and at 2-months. A parallel process growth model was used. Baseline child SHSe and smoking were correlated (r = 0.30). Changes in child SHSe and child smoking moved in tandem as evidenced by a correlation between the linear slopes of child smoking and SHSe (r = 0.32), and a correlation between the linear slope of child smoking and the quadratic slope of child SHSe (r = - 0.44). Results may inform interventions with the potential to reduce child SHSe and smoking among children at increased risk due to their exposure to parental smoking.

Relationship between Parental Bonding and Tobacco Specific Practices as Predictors of Tobacco Usage in Adults

INTRODUCTION

Parents influence their child's conduct and adolescence hostility either directly or indirectly. Similarly children can acquire a particular behaviour by observing and intentionally imitating their parents in order to simply copy them without understanding the positive or negative outcome.

AIM

To assess and compare the association between parental tobacco usage and parental bonding with participants tobacco usage habits.

MATERIALS AND METHODS

A descriptive cross-sectional study was conducted among 130 adults. Information pertaining to demographics, parental bonding (using parental bonding index) and behavioural habits (e.g., smoking, alcohol) of both participants and their parents was collected with the use of a questionnaire-based interview. Tobacco usage was measured as categorical variable as ever chewer and never chewer. Chi-square test, independent sample t-test, multinomial logistic regression and rotated factor loadings was used to analyse the data.

RESULTS

Majority of the participants were males with a mean age of 30.4±8.5 years. Tobacco use was prevalent among less educated males. Parental smokeless tobacco use, paternal alcohol and maternal paan chewing was significantly associated with participants adverse habits. Multinomial logistic regression showed a significant association between parental and participant's tobacco usage. Perceived parental bonding were also significantly associated with participant's tobacco usage habit.

CONCLUSION

Parental bonding measures and tobacco usage was significantly associated with the participant's tobacco use. Hence, interventional and educational efforts to weaken intergenerational influences should target parents. In addition to parents, the smoking behaviour of adults should also be targeted for prevention efforts.

Smoking among school-going adolescents in selected secondary schools in Peninsular Malaysia- findings from the Malaysian Adolescent Health Risk Behaviour (MyaHRB) study

BACKGROUND

A multitude of studies have revealed that smoking is a learned behaviour during adolescence and efforts to reduce the incidence of smoking has been identified as long-term measures to curb the smoking menace. The objective of this study was to determine the prevalence as well as the intra and inter-personal factors associated with smoking among upper secondary school students in selected schools in Peninsular Malaysia.

METHODS

A study was carried out in 2013, which involved a total of 40 secondary schools. They were randomly selected using a two-stage clustering sampling method. Subsequently, all upper secondary school students (aged 16 to 17 years) from each selected school were recruited into the study. Data was collected using a validated standardised questionnaire.

RESULTS

This study revealed that the prevalence of smoking was 14.6% (95% CI:13.3-15.9), and it was significantly higher among males compared to females (27.9% vs 2.4%, p < 0.001). Majority of smokers initiated smoking during their early adolescent years (60%) and almost half of the respondents bought cigarettes themselves from the store. Multivariable analysis revealed that the following factors increased the likelihood of being a current smoker: being male (aOR 21. 51, 95% CI:13.1-35), perceived poor academic achievement (aOR 3.42, 95% CI:1.50-7.37) had one or both parents who smoked (aOR 1.80, 95% CI:1.32-2.45; aOR 6.50, 95 CI%:1.65-25.65), and always feeling lonely (aOR 2.23, 95% CI:1.21-4.43). In contrast, respondents with a higher religiosity score and protection score were less likely to smoke (aOR 0.51, 95% CI:0.15-0.92; aOR 0.71, 95% CI 0.55-0.92).

CONCLUSION

This study demonstrated that the prevalence of smoking among Malaysian adolescents of school-going age was high, despite implementation of several anti-smoking measures in Malaysia. More robust measures integrating the factors identified in this study are strongly recommended to curb the smoking epidemic among adolescents in Malaysia.

Prevalence and determinants of smoking initiation among school students in Bosnia and Herzegovina

BACKGROUND

Tobacco smoking amongst the young is a matter of public health concern because of the immediate and long-term health consequences associated with tobacco use, such as asthma, cancers, and cardiovascular diseases. The purpose of this study was to identify the determinants of smoking initiation among a sample of high school students in Bosnia and Herzegovina.

METHODS

The study was conducted among 198 high school students in Zvornik, Bosnia and Herzegovina, during April 2013. A self-administered, pre-tested, structured, close-ended questionnaire was used for data collection.

RESULTS

Fourth grade students mainly initiated smoking in high school (45%), while the majority of third and second grade students initiated smoking in primary school. Among students who smoke, an average duration of the smoking habit was <2 years. A multivariate analysis showed that males were 5.27 times more likely to have initiated smoking. For every unit increase in pro-smoking attitude towards smoking, students were 5.3 times more likely to have initiated smoking. Those with parents and friends who are smokers were 6.106 and 5.175 times, respectively, more likely to have initiated smoking.

CONCLUSION

This study indicates that a high proportion of 15-18 year olds in the town of Zvornik are current smokers. Gender, age, and parent and peer influence were identified as important associations with smoking. Interventions should not only be confined to the secondary school environment but they should also extend to their places of residence so that influences in the home environment and social surroundings that contribute to tobacco use are also tackled.

Preventing smoking in children and adolescents: Recommendations for practice and policy

Canada has witnessed a general decrease in smoking prevalence among all age groups in recent years. However, despite large numbers of campaigns and interventions, thousands of young Canadians continue to initiate cigarette smoking every year. The increasing popularity of alternative tobacco products and e-cigarettes is also creating new health challenges. Research has shown that the deleterious effects of nicotine and cigarette smoke are significant and long lasting. Health care professionals have key responsibilities in preventing tobacco use among youth and their families, and need to know more about effective smoking prevention and cessation strategies. Clinicians need to integrate tobacco counselling into health assessments of teenagers and be aware of the roles that families, communities and governments can play in promoting tobacco-free environments. Information, effective strategies and opportunities for health care professionals to intervene and advocate for Canadian adolescents are discussed.

Intergenerational Patterns of Smoking and Nicotine Dependence Among US Adolescents

OBJECTIVES

We examined associations between parental and adolescent smoking and nicotine dependence in the United States.

METHODS

We used data from the 2004 to 2012 National Survey on Drug Use and Health, which ascertained smoking behaviors of 1 parent and 1 adolescent aged 12 to 17 years in 35 000 dyads. We estimated associations between parental and adolescent smoking behaviors, adjusted for covariates.

RESULTS

Parental current dependence was strongly associated with adolescents' lifetime smoking (adjusted odds ratio [AOR] = 2.96; 95% confidence interval [CI] = 2.47, 3.55), whereas parental current nondependent smoking (AOR = 2.26; 95% CI = 1.92, 2.67) and former smoking (AOR = 1.51; 95% CI = 1.31, 1.75) were less strongly associated. Only parental nicotine dependence was associated with adolescent nicotine dependence (AOR = 1.66; 95% CI = 1.00, 2.74). Associations between parental and adolescent smoking did not differ by race/ethnicity. Parents' education, marital status, and parenting and adolescents' mental health, beliefs about smoking, perception of schoolmates' smoking, and other substance use predicted adolescent smoking and dependence.

CONCLUSIONS

Reducing parental smoking would reduce adolescent smoking. Prevention efforts should encourage parental smoking cessation, improve parenting, address adolescent mental health, and reinforce adolescents' negative beliefs about smoking.

Parent voices guide smoking intervention development

Purpose

– While parents’ influence on their children’s smoking behaviour is widely recognised, little is known about parents of four to eight year olds’ attitudes and beliefs around smoking cessation and how they communicate with their children about smoking. The purpose of this paper is to explore parents’ perceptions of quitting smoking and their beliefs and actions related to the use of parenting practices to discourage smoking by their children.

Design/methodology/approach

– Four focus groups and 17 interviews were conducted with parents (n=46) of four to eight year old children in Perth, Western Australia.

Findings

– Many parents indicated their children strongly influenced their quitting behaviours, however, some resented being made to feel guilty about their smoking because of their children. Parents were divided in their beliefs about the amount of influence they had on their children’s future smoking. Feelings of hypocrisy appear to influence the extent to which parents who smoked talked with their child about smoking. Parents recommended a variety of resource options to support quitting and talking with their child about smoking.

Practical implications

– Interventions aimed at parents who smoke and have young children should: reinforce parents’ importance as role models; highlight the importance of talking to children about smoking when they are young and provide strategies for maintaining ongoing communication; be supportive and avoid making parents feel guilty; and emphasise that quitting smoking is the best option for their child’s health (and their own), while also providing effective harm minimisation options for parents who have not yet quit.

Originality/value

– Parents of children of lower primary school age can be highly influential on their children’s later smoking behaviours, thus, effective interventions that address the current beliefs and practices of these parents may be particularly advantageous.

A Motivational, Gender-Sensitive Smoking Cessation Resource for Family Members of Patients With Lung Cancer

PURPOSE/OBJECTIVES

To gather feedback on an innovative gender-sensitive booklet that draws on emotional connections and relationship factors to motivate smoking cessation.

RESEARCH APPROACH

Qualitative, descriptive.

SETTING

Six provinces in Canada.

PARTICIPANTS

30 family members of patients with lung cancer who were currently smoking or had recently quit.

METHODOLOGIC APPROACH

Parallel booklets for women and men were developed using language and images to emphasize family relationships and gender considerations to motivate smoking cessation. Participants were provided with the women's and men's versions of the resource, and they were asked to review the gender-specific version of the booklet that was relevant to them. Semistructured telephone interviews were conducted, and transcriptions were analyzed for themes.

FINDINGS

Three themes were evident in the data, including "new perspectives.

CONCLUSIONS

A gender-sensitive approach that focuses on relationship factors represents an acceptable way to engage relatives of patients with lung cancer in discussions to support smoking cessation.

INTERPRETATION

Approaches to supporting smoking cessation among relatives of patients diagnosed with lung cancer should draw on positive relationship bonds and caring connections to motivate cessation.

Smoking among Saudi students: a review of risk factors and early intentions of smoking

This review aims to determine the prevalence of smoking among Saudi students and to study and to identify, synthesize and summarize the predictors that initiate smoking among students in different ages in Saudi Arabia. Different databases were searched (Web of Science, Google Scholar, Pub Med and Science Direct) with keywords. This search was carried out in October 2013. Studies that included were evaluated for methodological soundness by giving a quality score based on Russell and Gregory's criteria. A total 12 relevant articles were included in this review. The findings show that the prevalence of smoking is still in higher rates. The age of smoking was started among adolescents ranged from 10 to 15 years old while from university students were from 16 years old. The main reason for smoking among adolescents was influenced by friends. Among college students were peer pressure followed by the stress, media and imitation of others. Curiosity was a reason for having tried smoking and parents was perceived to be the first source for smoking. Religion was considered the main factor against smoking among the adolescent non-smokers and health consideration among college students. Appropriate smoking control programs on adolescent should be initiated they become the future professionals of the society. Smoking control programs should be considered in this group.

A Comparison of Survey Measures and Biomarkers of Secondhand Tobacco Smoke Exposure among Nonsmokers

OBJECTIVES

Secondhand tobacco smoke (SHS) exposure causes several adverse physical health outcomes. Conceptual differences in survey measures of 'psychosocial' (SHS exposure from smokers in an individual's life) and 'physical' (environments where an individual is exposed to SHS) SHS exposure exist. Few studies have examined the association between psychosocial and physical SHS exposures measures in comparison to biomarkers of SHS exposure.

DESIGN AND SAMPLE

A secondary analysis of cross-sectional data was examined among a convenience sample of 20 adults.

MEASURES

Data included survey items on SHS exposure and hair nicotine and saliva cotinine levels. Spearman analysis was used to assess correlations among variables.

RESULTS

Medium and strong correlations were found among SHS exposure measures with the exception of saliva cotinine levels. Strong correlations were found among and between psychosocial and physical SHS exposure measures. Hair nicotine levels had medium strength associations with only perceived frequency of SHS exposure.

DISCUSSION

As psychosocial measures of exposure were associated with biomarkers, such measures (particularly perceived frequency of SHS exposure) should be added to surveys in addition to physical SHS exposure measures to enhance accuracy of SHS measurement. Future explorations with robust sample sizes should further examine the strength of relationship between psychosocial and physical SHS exposure measures.

The Effects of Antismoking Messages From Family, School, and Mass Media on Smoking Behavior and Smoking Intention Among Chinese Adolescents

The prevalence of adolescent smoking has been increasing rapidly in China. Expanding adolescent exposure to antismoking messages may be an effective approach to prevent tobacco use among this population. Using a cross-sectional sample of 8,444 high school students in four Chinese cities, this study assessed the relation between self-reported exposure to antismoking messages from families, schools, and mass media and the rate of past 30-day smoking and smoking intention among junior and senior high school students. Results from logistic regression suggested that antismoking messages delivered via school and media inhibited both tobacco use and the intention to smoke. The effects of familial warnings about harmful effects of smoking, in contrast, were at best insignificant.

Promoting smoking cessation among parents: effects on smoking-related cognitions and smoking initiation in children

BACKGROUND

Parental smoking is associated with an increased risk of smoking among youth. Epidemiological research has shown that parental smoking cessation can attenuate this risk. This study examined whether telephone counselling for parents and subsequent parental smoking cessation affect smoking-related cognitions and smoking initiation among children of smoking parents.

METHODS

Data of a two-arm randomized controlled trial were used in which 512 smoking parents were recruited into cessation support through their children's primary schools. After the baseline assessment, smoking parents were randomly assigned to tailored telephone counselling or a standard self-help brochure. Parental cessation was measured as 6-month prolonged abstinence at the 12-month follow-up. Children's smoking-related cognitions and smoking initiation were examined at 3-month, 12-month, and 30-month follow-up.

RESULTS

No statistical evidence was found that children of parents who received telephone counselling tailored to smoking parents or children of parents who achieved prolonged abstinence differ in smoking-related cognitions (i.e., smoking outcome expectancies, perceived safety of smoking, self-efficacy to refrain from smoking, susceptibility to smoking) or smoking initiation rate on any follow-up assessment.

CONCLUSIONS

This study is the first to examine the effects of an evidence-based smoking cessation treatment for parents and treatment-induced parental smoking cessation on cognitive and behavioural outcomes among children. Although descriptive statistics showed lower smoking initiation rates among children of parents who achieved prolonged abstinence, there was no statistical evidence that telephone counselling tailored to parents or treatment-induced parental smoking cessation affects precursors of smoking or smoking initiation among youth.

Parental smoking exposure and adolescent smoking trajectories

OBJECTIVE

In a multigenerational study of smoking risk, the objective was to investigate the intergenerational transmission of smoking by examining if exposure to parental smoking and nicotine dependence predicts prospective smoking trajectories among adolescent offspring.

METHODS

Adolescents (n = 406) ages 12 to 17 and a parent completed baseline interviews (2001-2004), and adolescents completed up to 2 follow-up interviews 1 and 5 years later. Baseline interviews gathered detailed information on parental smoking history, including timing and duration, current smoking, and nicotine dependence. Adolescent smoking and nicotine dependence were assessed at each time point. Latent Class Growth Analysis identified prospective smoking trajectory classes from adolescence into young adulthood. Logistic regression was used to examine relationships between parental smoking and adolescent smoking trajectories.

RESULTS

Four adolescent smoking trajectory classes were identified: early regular smokers (6%), early experimenters (23%), late experimenters (41%), and nonsmokers (30%). Adolescents with parents who were nicotine-dependent smokers at baseline were more likely to be early regular smokers (odds ratio 1.18, 95% confidence interval 1.05-1.33) and early experimenters (odds ratio 1.04, 95% confidence interval 1.04-1.25) with each additional year of previous exposure to parental smoking. Parents' current non-nicotine-dependent and former smoking were not associated with adolescent smoking trajectories.

CONCLUSIONS

Exposure to parental nicotine dependence is a critical factor influencing intergenerational transmission of smoking. Adolescents with nicotine-dependent parents are susceptible to more intense smoking patterns and this risk increases with longer duration of exposure. Research is needed to optimize interventions to help nicotine-dependent parents quit smoking early in their children's lifetime to reduce these risks.

Cigarette smoking in obsessive-compulsive disorder and unaffected parents of OCD patients

BACKGROUND

Cigarette smoking is more prevalent among individuals with psychiatric disorders than the general population. Obsessive-compulsive disorder (OCD) may be an intriguing exception, although no recent study has investigated this hypothesis in OCD patients. Moreover, it is unknown whether reduced smoking rates are present in unaffected first-degree relatives of OCD patients.

METHODS

We assessed smoking prevalence in adults with OCD and unaffected parents of youth with OCD (PYOCD). To this end, 113 adults with OCD completed online questionnaires assessing symptom severity and smoking status. Smoking status was obtained from an independent sample of 210 PYOCD assessed for psychiatric diagnoses.

RESULTS

Smoking prevalence rates in adults with OCD (13.3%; n=15) and PYOCD (9.5%; n=20) samples were significantly lower than those found in representative samples of the general population (19-24%, all P<.001) and Axis I disorders (36-64%; all P<.001). There were no smokers in the adult OCD subset without clinically significant depressive symptoms (n=54).

CONCLUSION

Low prevalence of smoking in OCD may be familial and unique among psychiatric disorders, and might represent a possible state-independent OCD marker. Hypotheses concerning the uncharacteristically low prevalence rates are discussed with relation to OCD phenomenology and pathophysiology.

Intergenerational transfer of smoking across three generations and forty-five years

OBJECTIVES

Although many have examined the linkages between smoking behaviors across 2 generations, few have examined these linkages among 3 generations.

METHODS

U.S. population representative data for 3 generations are drawn from the Panel Study of Income Dynamics (PSID) in order to examine whether smoking behaviors are passed down from generation to generation and the magnitude of the influence of smoking behaviors across generations (N = 830).

RESULTS

Results indicate direct linkages between both grandparent (G1) and parent (G2) smoking (OR = 4.53; 95% CI = 2.57-7.97) and parent (G2) and young adult offspring (G3) smoking (OR = 2.91; 95% CI = 1.60-5.31). Although the direct link between grandparent (G1) and grandchildren (G3) was not significant (OR = 2.25; 95% CI = 0.96-5.23, p < .10), mediation analyses reveal that the link between G3 and G1 smoking is significantly mediated by G2 smoking.

CONCLUSIONS

Regardless of generation, parent smoking behavior has a direct influence on offspring smoking behavior. The link between grandparent (G1) and grandchild (G3) smoking is mediated by parent (G2) smoking, suggesting that smoking behavior is passed from one generation to the next generation and in turn to the next generation.

Short-term effects of a home-based smoking prevention program on antismoking socialization and smoking-related cognitions: a cluster randomized controlled trial

OBJECTIVE

This study aims to evaluate the short-term effects of a home-based smoking prevention program called 'Smoke-free Kids' on antismoking socialization and smoking-related cognitions and the moderating role of parental smoking.

PARTICIPANTS AND METHODS

A cluster randomized controlled trial was carried out using one intervention condition compared with a control condition. A total of 1,398 never-smoking children (mean age 10.11 years, SD 0.78) participated. Intention-to-treat and completers-only analyses were performed. Participants in the intervention condition (n=728) received 5 activity modules by mail at 4-week intervals. Modules included communication sheets for their mothers. Participants in the control condition (n=750) received a fact-based intervention only. The main outcomes were the frequency and quality of communication, nonsmoking agreement, house rules, availability of cigarettes, perceived maternal influence, anticipated maternal reactions, attitude, self-efficacy and social norms.

RESULTS

Significant effects of the program were found for frequency of communication (B=0.11, p<0.001), nonsmoking agreement (B=0.07, p<0.01), perceived maternal influences (B=0.09, p<0.05), self-efficacy (B=-0.09, p<0.05) and social norms of friends (B=-0.08, p=0.05) and best friends (B=-0.11, p<0.05). Parental smoking had no moderating effect.

CONCLUSIONS

The Smoke-free Kids program shows promising short-term effects on antismoking socialization and cognitions. Long-term follow-up on the effects of smoking behavior are needed.

Enhanced motivational interviewing versus brief advice for adolescent smoking cessation: results from a randomized clinical trial

BACKGROUND

Motivational interviewing (MI) is widely used for adolescent smoking cessation but empirical support for this approach is mixed.

METHODS

Adolescent cigarette smokers 14-18 years old (N=162) were recruited from medical, school, and community settings and randomly assigned to enhanced MI or brief advice (BA) for smoking cessation. MI comprised an in-person individual session, a telephone booster session one week later, and a brief telephone-based parent intervention. BA consisted of standardized brief advice to quit smoking. Assessments occurred at baseline, post-treatment and at 1-, 3-, and 6-month follow ups.

RESULTS

Biochemically-confirmed 7-day point prevalence abstinence rates were low (e.g., 4.5% for MI; 1.4% for BA at 1 month) and did not differ significantly by group at any follow up. Only those in MI reported significant decreases in cigarettes smoked per day (CPD) from baseline to 1 month. At 3 and 6 months, smokers in both groups reported significantly reduced CPD with no differences between groups. MI reduced perceived norms regarding peer and adult smoking rates, while BA had no effect on normative perceptions. No group differences emerged for self-reported motivation or self-efficacy to quit smoking.

CONCLUSIONS

Findings support the efficacy of MI for addressing normative misperceptions regarding peer and adult smoking and for modestly reducing CPD in the short-term; however, these effects did not translate to greater smoking abstinence. MI may have more promise as a prelude to more intensive smoking intervention with adolescents than as a stand-alone intervention.

Smoking cessation-specific parenting and parental smoking as precursors of adolescent smoking cognitions and quitting

Relatively little is known about if and through which mechanisms parents influence adolescents' smoking cessation. The present study used Social Cognitive Theory as a theoretical framework to test whether parental smoking and smoking cessation-specific parenting (SCSP) predicted readiness to quit smoking and actual smoking cessation one year later. Both direct paths between parent factors and outcomes, and indirect paths via adolescents' smoking-specific cognitions (pros of smoking and quitting, and self-efficacy) were examined in a sample of 530 adolescents in the ages of 13 to 18 who smoked daily and weekly at baseline. The main findings show that although parental smoking and SCSP were significantly associated with cognitions (cross-sectionally), neither the parent factors nor cognitions predicted readiness to quit smoking or actual cessation one year later. Baseline SCSP did predict readiness to quit one year later. Parents may be more influential in shaping adolescents' beliefs and readiness to quit than in facilitating actual cessation.

A review of culturally targeted/tailored tobacco prevention and cessation interventions for minority adolescents

AIM

Emerging racial/ethnic disparities in tobacco use behaviors and resulting long-term health outcomes highlight the importance of developing culturally tailored/targeted tobacco prevention and cessation interventions. This manuscript describes the efficacy and the components of prevention and cessation interventions developed for minority adolescents.

METHODS

Thirteen studies focused on culturally tailoring and targeting tobacco prevention/cessation interventions were selected and information on intervention design (type, number of sessions), setting (school or community), theoretical constructs, culture-specific components (surface/deep structures), and treatment outcomes were extracted.

RESULTS

Of the 13 studies, 5 focused on prevention, 4 on cessation, and 4 combined prevention and cessation, and most of the studies were primarily school-based, while a few used community locations. Although diverse minority groups were targeted, a majority of the studies (n = 6) worked with Hispanic adolescents. The most common theoretical construct examined was the Social Influence Model (n = 5). The overall findings indicated that culturally tailoring cessation interventions did not appear to improve tobacco quit rates among minority adolescents, but culturally tailored prevention interventions appeared to produce lower tobacco initiation rates among minority adolescents than control conditions.

CONCLUSIONS

The results of review suggest that there is a critical need to develop better interventions to reduce tobacco use among minority adolescents and that developing a better understanding of cultural issues related to both cessation and initiation of tobacco use among minority populations is a key component of this endeavor.

Peering through the smoke: the effect of parental smoking behavior and addiction on daily smokers' attentional bias to smoking cues

Although previous research has demonstrated that individuals with parents who smoke are more likely to become smokers and are less successful in smoking cessation efforts compared with those without a smoking parent, the reasons for this link have not been established. In the current study, implicit attentional bias to smoking-related cues was investigated in college-age smokers, based on models of addiction that suggest that attention to drug-related cues plays an important role in drug addiction. Sixty-one participants completed a dot-probe task to measure attentional bias to smoking-related and matched non-smoking-related control pictures. Results indicated that while those who reported smoking occasionally did not demonstrate an attentional bias, daily smokers who had a smoking parent showed more of an attentional bias to the smoking cues than those without a smoking parent, but only to cues that did not contain human content. In addition to parental influence, nicotine dependence explained a significant portion of the variance in the attentional bias for daily smokers. Implications for models of nicotine addiction and the development of smoking cessation programs are discussed.
