Protecting Children From Tobacco, Nicotine, and Tobacco Smoke

Association between biomarkers of tobacco smoke exposure and clinical efficacy of ivacaftor in the G551D observational trial (GOAL)

BACKGROUND

Acrolein, an aldehyde in smoke from tobacco products, inhibits CFTR function in vitro. Ivacaftor is an FDA-approved potentiator that improves mutant CFTR function. This human clinical study investigated the relationship between two urinary markers of tobacco smoke exposure - the acrolein metabolite 3-HPMA and the nicotine metabolite NNAL - and sweat chloride response to ivacaftor in the G551D Observational Trial (GOAL).

METHODS

3-HPMA (low: <50th centile; moderate: 50-75th centile; high: >75th centile) and NNAL (detectable/undetectable) in GOAL samples was quantified with LC-MS/MS. Self-report of tobacco smoke exposure (Y/N) served as a subjective measure. Change in sweat chloride from pre- to 6 months post-ivacaftor treatment (ΔSC) was the primary CFTR-dependent readout.

RESULTS

The sample included 151 individuals, mean age 20.7 (SD 11.4) years, range 6-59 years. Smoke exposure prevalence was 15 % per self-reports but 27 % based on detectable NNAL. 3-HPMA was increased in those reporting tobacco smoke exposure (607 vs 354 ng/ml, p = 0.008), with a higher proportion of smoke-exposed in the high- vs low-acrolein group (31 % vs 9 %, p=0.040). Compared to low-acrolein counterparts, high-acrolein participants experienced less decrease in sweat chloride (-35.2 vs -48.2 mmol/L; p = 0.020) and had higher sweat chloride values (50.6 vs 37.6 mmol/L; p = 0.020) 6 months post-ivacaftor. The odds of ivacaftor-mediated potentiation to near normative CFTR function (defined as SC6mo <40 mmol/L) was more than twice as high in the low-acrolein cohort (OR: 2.51, p = 0.026).

CONCLUSIONS

Increased urinary 3-HPMA, an acrolein metabolite of tobacco smoke, is associated with a diminished sweat chloride response to ivacaftor potentiation of CFTR function.

Trends of electronic cigarette use among adolescents: A bibliometric analysis

INTRODUCTION

The use rate of electronic cigarettes (e-cigarettes) among adolescents is continuously rising globally, posing new challenges to public health and negatively impacting adolescent health. This study employs bibliometric methods to systematically present the current state and evolving trends in global research on adolescent e-cigarette use.

METHODS

This study uses CiteSpace to conduct a bibliometric analysis of articles related to adolescent e-cigarette use from the Web of Science (WoS) Core Collection database. Firstly, performance analysis and collaboration network analysis were utilized to clarify the basic publication status, main knowledge producers, and knowledge collaboration networks in adolescent e-cigarette use research. Secondly, a co-citation network analysis was performed to visually analyze the disciplinary characteristics and 'hot topics' in this field. Finally, keyword burst detection and clustering techniques were employed to further explain the development trends and frontiers of research on adolescent e-cigarette use.

RESULTS

A total of 2063 research articles and review articles were included in this study. Research on adolescent e-cigarette use has significantly increased from 2002 to 2024. The United States, the United Kingdom and Canada are the main contributors, with their institutions and researchers playing key roles in the international collaborative network. Current research increasingly adopts interdisciplinary approaches. Keyword co-occurrence and burst identified current research 'hotspots' including vaping, substance use, public policy, prevention, advertising, and cessation. Co-citation cluster analysis revealed promising research areas such as attractiveness, environment and health, accessibility and smoking behavior, and mental health.

CONCLUSIONS

Through data mining and visualization techniques, this study provides a comprehensive bibliometric analysis of published work on e-cigarettes and adolescence. The results of this work offer references for researchers in future investigations.

Comparison of Cardiovascular Health Between Parents and Non-Parents in NHANES 2011-2018

BACKGROUND AND OBJECTIVES

We compared cardiovascular health for parents and non-parents using the American Heart Association's Life's Essential 8 (LE8).

METHODS

This cross-sectional cohort analyzed 2011-2018 NHANES participants aged 20 to 54. The exposure was parenting, defined as living with a child. Logistic regression assessed whether parenting was associated with odds of ideal LE8 total or sub-scores. Regression adjusted for age, sex, race and ethnicity, educational attainment, marital status, and income. Subgroups included female sex, male sex, income <150% federal poverty levels, and parents of younger children.

RESULTS

6847 participants represented a weighted population of 79 120 285 (57% parents). Parenting was not associated with adjusted odds of ideal total LE8 (OR 0.91, 95% CI 0.76-1.09). Parenting was associated with decreased odds of ideal body mass index (BMI) (OR 0.81, 95% CI 0.72-0.91) and increased odds of smoking avoidance (OR 1.22, 95% CI 1.09-1.38). Associations varied by subgroup. Only the subgroup with lower incomes demonstrated reduced odds of ideal total LE8 for parents (OR 0.58, 95% CI 0.41-0.82).

CONCLUSIONS

Parents and non-parents differed in smoking and BMI, though not in LE8 total. Families with low incomes may particularly benefit from dual generation cardiovascular risk reduction.

Role of parental smoking and environmental tobacco smoke exposure in childhood cancer: A study using hair cotinine analysis and questionnaires

OBJECTIVES

In the etiology of childhood cancers, many genetic and environmental factors play a role. One of these factors could be cigarette smoking, and the main source of tobacco smoke exposure of children is parental smoking. However, establishing a causal relationship between parental smoking and childhood cancers has proven challenging due to difficulties in accurately detecting tobacco smoke exposure METHODS: To address this issue, we used hair cotinine analysis and a questionnaire to get information about tobacco smoke exposures of pediatric cancer patients and healthy children. A total of 104 pediatric cancer patients and 99 healthy children participated in our study. Parental smoking behaviors (pre-conceptional, during pregnancy, and current smoking) and environmental tobacco smoke (ETS) exposures of children are compared.

RESULTS

We have found no differences between two groups by means of maternal smoking behaviors. However, the rates of paternal pre-conceptional smoking and smoking during pregnancy were significantly low in cancer patients (p < .05). These data suggest that social desirability bias among fathers of cancer patients may have contributed to this discrepancy. According to questionnaire, cancer patients had significantly lower ETS exposures than healthy children (p < .05). However, ETS exposure assessment through cotinine analysis demonstrated that cancer patients had higher exposure to ETS compared to healthy children (p < .001).

CONCLUSION

Our findings provide evidence supporting the potential role of smoking as a risk factor for childhood cancers. This study also revealed that questionnaires could cause biases. We suggest that cotinine analysis along with validated questionnaires can be used to prevent biases in studies of tobacco smoke in the etiology of childhood cancers.

The Diverging Trend in Exposure to Environmental Tobacco Smoke Among US Children

OBJECTIVE

Environmental tobacco smoke exposure (ETSE) was race/ethnicity-specific, but how the race/ethnicity-specific ETSE has changed over time, diverging or converging, remains unclear. We examined ETSE trends by race/ethnicity in US children aged 3-11 years.

METHODS

We analyzed the data of 9678 children who participated in the biennial National Health and Nutrition Examination Surveys, 1999-2018. ETSE was defined as serum cotinine ≥ 0.05 ng/ml, with ≥ 1 ng/ml as heavy exposure. For trend description, adjusted biennial prevalence ratios (abiPR: the ratio associated with a 2-year increase in time) were estimated by race/ethnicity. The prevalence ratios between races/ethnicities were used to quantify ethnoracial differences in different survey periods. Analyses were performed in 2021.

RESULTS

The overall ETSE prevalence was cut by almost half, from 61.59% (95% confidence interval = 56.55%, 66.62%) in the 1999-2004 survey to 37.61% (33.90%, 41.31%) in 2013-2018, exceeding the national 2020 health target (47.0%). However, the decrease occurred unequally between races/ethnicities. Heavy ETSE declined significantly in white [abiPR = 0.80 (0.74, 0.86)] and Hispanic children [0.83 (0.74, 0.93)], but insignificantly in black children [0.97 (0.92, 1.03)]. Consequently, the adjusted prevalence ratio between black children and white children increased from 0.82 (0.47, 1.44) in 1999-2004 to 2.73 (1.51, 4.92) in 2013-2018 for heavy ETSE. Hispanic children remained at the lowest risk throughout the study period.

CONCLUSION

Overall ETSE prevalence was cut by half between 1999 and 2018. However, due to uneven declines, the gaps between black children and others have expanded in heavy ETSE. Special vigilance is needed in preventive medicine practice with black children.

What can be done to protect toddlers from air pollution: Current evidence

PROBLEM

Toddlers are more prone to exposure to widely distributed air pollution and to health damage from it. However, systematic summaries of evidence on protective behaviors against air pollution for toddlers are lacking.

OBJECTIVE

To identify currently available evidence on protective behaviors against air pollution for toddlers.

METHODS

The literature retrieval was performed in selected databases, limited from 2002 to 2022. Studies meeting the following criteria were included and praised: 1) clinical practice guideline, systematic review, expert consensus, recommended practice, randomized control test (RCT) or cohort study published in Chinese or English; 2) studies reporting effects of protective behaviors against air pollution on toddlers' health outcomes or providing recommendation on these behaviors. The evidence in the included studies was extracted, synthesized and graded for evidence summary.

RESULTS

Studies (N = 19) were used for evidence summary development and 35 pieces of best evidence were synthesized, which were divided into three categories, including "avoiding or reducing air pollution generation", "removing existing air pollution", and "avoiding or reducing exposure to existing air pollution".

CONCLUSIONS

More evidence is needed to identify protective measures against outdoor air pollution and tobacco smoke. Research in the future should focus on the safety, effectiveness and feasibility of universal measures implemented in toddlers, and try to develop protective measures specific to toddlers which highlight their special nature.

IMPLICATIONS

The results of this study can help pediatric nurses provide individualized advice and assistance for toddlers and their families, and conduct research on the effectiveness of toddler-targeting protective behaviors more efficiently.

A multilevel intervention in pediatric primary care for youth tobacco control: Outcomes of implementing an Ask, Advise, and Connect model

Multilevel interventions in healthcare settings (e.g. Ask, Advise, and Connect; AAC) can reduce tobacco product use among adult patients: their effectiveness in pediatric practice is largely unknown. We implemented an AAC model in pediatric primary care to deter children's tobacco use, and evaluated its effectiveness in a single-arm trial. At wellness visits, young patients (ages 12-17) completed a tablet-based assessment (Ask) of lifetime and current tobacco use. These data were made available within the electronic health record to pediatric primary care providers for preventive counseling (Advise). Providers then referred patients to an e-health evidence-based tobacco control intervention (Connect). Tobacco control outcomes were examined in the clinic population (N = 2219) and in a sample of patients (N = 388, 62% female, 39% non-White, M age = 15) over time, along with intervention engagement. Population use of tobacco products decreased following introduction of AAC (more than 2-fold). At the patient level, most children (80.9%) engaged with the intervention: those who were Black or African American, who never used tobacco products/were not susceptible to use, and who used fewer non-cigarette tobacco products were more likely to engage, but only after multiple prompts versus a single prompt. Engagement was positively associated with lowering children's susceptibility to using tobacco at follow-up. A pediatric AAC model holds promise in deterring youth tobacco use, including among historically marginalized populations who may require additional support.

Assessment of the Smoke Free Families Tobacco Screening, Counseling, and Referral Program in Pediatric Primary Care Practices

OBJECTIVE

The Smoke Free Families (SFF) program trained pediatric providers to use an SFF tool during well-child visits (WCVs) of infants ≤12 months to "Ask" caregivers about tobacco use, "Advise" smokers to quit, and "Refer" smokers to cessation services (AAR). The primary objectives were to assess the prevalence and changes in caregiver tobacco use after being screened and counseled by providers using the SFF tool. A secondary objective was to examine providers' AAR behavior facilitated by using the SFF tool.

METHODS

Pediatric practices participated in 1 of 3 6-9-month SFF program waves. Over the 3 waves, all initial SFF tools completed on caregivers during their infant's WCV were evaluated for the caregiver and household tobacco use and providers' AAR rates. An infant's first and next WCV was matched to determine changes in caregiver tobacco product use.

RESULTS

In total, the SFF tool was completed at 19,976 WCVs; 2081 (18.8%) infants were exposed to tobacco smoke. A total of 834 (74.1%) caregivers who smoked received counseling: 786 (69.9%) were advised to quit, 700 (62.2%) were given cessation resources, and 198 (17.6%) were referred to the Quitline. In total, 230 (27.6%) of caregivers who smoked had a second visit; 58 (25.2%) self-reported that they quit using tobacco. Among cigarette users (n = 183), 89 (48.6%) reported that they used fewer cigarettes or quit at their infants' second WCV.

CONCLUSIONS

Systematic use of the SFF AAR tool during infants' WCVs could improve the health of caregivers and children, resulting in decreases in tobacco-related morbidity.

Screening and Counseling Practices for Parental Combustible Versus Electronic Cigarette Use in Pediatric Primary Care: A Pilot Study

OBJECTIVE

Tobacco exposure plays an important role in children's health. Little is known about pediatrician's experience with parental e-cigarette use. This pilot study aimed to assess pediatrician's knowledge, attitude, and behaviors regarding parental e-cigarette use.

METHODS

This cross-sectional survey at an academic clinic assessed residents' and attendings' knowledge, attitudes, and behaviors regarding parental combustible and e-cigarette use and counseling and cessation barriers.

RESULTS

Sixty of 69 care providers completed the survey. Participants reported asking about parental use (5% vs 58%, Δ = 53% [95% CI Δ = 40%-67%]), advising about harms (5% vs 52%, Δ = 47% [95% CI Δ = 33%-61%]), and assisting with quitting (2% vs 28%, Δ = 27% [95% CI Δ = 15%-39%]) significantly less for e-cigarettes than for combustible cigarettes. The most common barrier to discussing use was lack of time. Lack of knowledge, unsure of harm, and lack of training were reported significantly more for e-cigarettes than for combustible cigarettes.

CONCLUSION

Parental screening and counseling rates are significantly lower for e-cigarettes than for combustible cigarettes in this pilot study. Increased training could help pediatricians better protect children from tobacco exposure.

Impact of a Multidisciplinary Curriculum Training Students and Residents in Tobacco Cessation Strategies for Adult Caregivers of Children

Introduction

Children's exposure to secondhand smoke is an underaddressed public health threat. The Clinical Effort Against Secondhand Smoke Exposure (CEASE) is a validated framework that trains pediatric providers to screen, counsel, refer to quitlines, and prescribe tobacco cessation medications to adult caregivers of children.

Methods

A physician champion at a major urban academic center delivered a longitudinal didactic curriculum of CEASE principles to medical and nurse practitioner students and pediatrics and family medicine residents. At the end of each session, participants completed an anonymous survey measuring changes in self-perceived knowledge, comfort, and familiarity with smoking cessation skills and concepts. Using a separate end-of-year questionnaire, we also surveyed a group of pediatric residents to compare the impact of CEASE training on clinical practice. Finally, we tracked the number of referrals to the state's quitline for the duration of the training.

Results

Fifty-two trainees (55% students, 45% residents) responded to the evaluation survey administered immediately following training. There were statistically significant improvements in median scores after CEASE training for comfort in screening, counseling, motivational interviewing, referring to smokers' helplines, and providing caregivers with nicotine replacement therapy (NRT) prescriptions. Fifty-one percent of pediatric residents (41 of 80) responded to the end-of-year survey, which showed statistically significant differences in the number of patients/caregivers offered a referral to California's quitline and prescription of NRT according to completion of CEASE training.

Discussion

CEASE training successfully improved the self-efficacy of health professions students and residents in smoking cessation techniques for adult caregivers of children.

Associations of household tobacco smoking status with childhood temperament among U.S. preschool-aged children

BACKGROUND

This study investigated the association between household tobacco smoking status and temperament among U.S. 3-5-year-olds.

METHODS

A secondary analysis of 2019-2020 National Survey of Children's Health data (N = 11,100) was conducted. Temperament dimensions of effortful control (characterized by attention focusing), negative affectivity (characterized by anger and soothability), and surgency (characterized by activity level and shyness) were assessed. Weighted ordinal regression models were conducted while adjusting for child and family covariates.

RESULTS

Approximately 13 % of children lived with smokers. Compared to children who did not live with smokers, children living with smokers displayed behaviors of poorer effortful control and were more likely to be easily distracted (AOR = 1.59, 95%CI = 1.24-2.04) and less likely to keep working on tasks until finished (AOR = 0.56, 95%CI = 0.44-0.71). Children living with smokers displayed behaviors of greater negative affectivity and were at increased odds of being angry or anxious when transitioning between activities (AOR = 1.50, 95%CI = 1.13-1.98) and losing their temper when things did not go their way (AOR = 1.53, 95%CI = 1.20-1.96), and were at decreased odds of calming down quickly when excited (AOR = 0.54, 95%CI = 0.42-0.70). Children living with smokers displayed behaviors of poorer surgency and were less likely to play well with others (AOR = 0.58, 95%CI = 0.45-0.76) and sit still compared to same-aged children (AOR = 0.56, 95%CI = 0.44-0.71).

LIMITATIONS

The NSCH uses a cross-sectional survey design; longitudinal associations and objective measures could not be assessed. However, the NSCH is nationally representative and results are generalizable to U.S. 3-5-year-olds.

CONCLUSIONS

Findings suggest household tobacco smoking influences temperament in early childhood. Results signify the need to promote household tobacco cessation.

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.

E-cigarettes and asthma in adolescents

PURPOSE OF REVIEW

E-cigarettes have been long purported to be a mechanism of harm reduction in current smokers. However, market expansion to adolescents has been aggressive, despite government interventions. Research examining the adverse effects of e-cigarettes in teens with asthma has been limited. We discuss the most recent data on the pulmonary manifestations of e-cigarettes use and exposure in adolescents with asthma.

RECENT FINDINGS

Adolescents with asthma are more likely to be e-cigarette users than those without asthma and more likely to have asthma exacerbations. Increased pulmonary inflammatory cytokines have been seen in e-cigarette users and mouse models. Yet, providers are not confident in e-cigarette screening and counselling despite acknowledging adolescents are using e-cigarettes regularly.

SUMMARY

Since the introduction of e-cigarettes into the United States market in 2007, adolescents use of these products has risen, even after a brief decline during the height of the COVID-19 pandemic. This review will describe the most recent studies on e-cigarette use trends, cytotoxicity of e-cigarette aerosol and associations with the diagnosis and symptoms of asthma. Knowledge gaps, advocacy efforts, evidence on e-cigarette cessation will be highlighted.

Advocacy for Global Tobacco Control and Child Health

Tobacco and secondhand smoke remain leading threats to public health. Evidence since the 1950s has shown that the tobacco industry has acted in bad faith to deceive the public about the health effects of smoking. They have specifically targeted vulnerable populations including children and adolescents with various-and often misleading-marketing efforts and promotions. The increased popularity and weak regulation of electronic cigarettes have created a new generation of smokers who mistakenly believe they are "safer" from harm. Continued research, advocacy, and government action are needed to protect public health. Public health advocates must know the evidence, build coalitions, and prepare for industry countermeasures. Persistence is key, but public health efforts have successfully decreased tobacco-related deaths.

Impacts of a Multicenter Medical Education Curriculum for Training Pediatric Residents on Tobacco Cessation for Adult Caregivers of Pediatric Patients

The Clinical Effort Against Secondhand Smoke Exposure (CEASE) is an evidence-based framework that increases pediatric providers' ability to address secondhand smoke exposure of minors. Physician champions at 4 University of California sites conducted regular 1-hour didactic trainings on CEASE principles to pediatric residents as part of a longitudinal curriculum. At the conclusion of the academic year, 111 of 284 residents (39%) completed an anonymous survey. CEASE-trained residents reported significantly higher rates than untrained residents of counseling on smoking cessation (adjusted odds ratio [OR] = 4.50, P = .009), and referring to the smokers' quitline (adjusted OR 3.6, P = .007) to 50% or more of their patients' caregivers who smoked. In addition, among CEASE-trained residents, there were significant increases in multiple post-training knowledge and self-efficacy items. Our results show that a brief educational curriculum can be helpful in changing pediatric residents' attitudes and behavior toward assisting adult caregivers to pediatric patients in smoking cessation.

Electronic Cigarette Use, Misuse, and Harm

Electronic cigarettes (e-cigarettes) are battery-powered devices that use heat to aerosolize a liquid containing a variety of substances (usually nicotine and/or cannabinoids, flavorings, and glycerol or propylene glycol base) that is then inhaled. E-cigarettes are rapidly evolving over time, so the true health effects of e-cigarettes are difficult to study and remain largely unknown. We review the effects of e-cigarettes on nicotine addiction and on pulmonary disease including the effects of dual use and switching from combustible cigarettes to e-cigarettes. Studies show that e-cigarette use can increase the risk to nicotine dependence and combustible tobacco use. Studies show an association between e-cigarette use and pulmonary disease. Some studies suggest reduced harm from e-cigarette use compared with smoking, but this requires further study. Most adults who use e-cigarettes also smoke cigarettes; epidemiologic studies suggest that the combination of e-cigarettes and cigarettes is more harmful than using either product alone.

A Close Look at Vaping in Adolescents and Young Adults in the United States

Vaping by adolescents and young adults is a legitimate concern as there is a risk that some may start smoking and that electronic cigarette (EC) use may have adverse effects in the developing lungs of adolescents. This commentary provides updated information on vaping patterns among adolescents and young adults in the United States, as well as the impact of EC usage on respiratory health. EC use has surged greatly among high school students and young adults over the last decade but fortunately has declined significantly since its peak in 2019. During the same time period, smoking rates have constantly fallen to new low record levels. These trends argue against EC use as a gateway to smoking. Most EC usage is infrequent and unlikely to increase a person's risk of negative health consequences. Furthermore, the majority of EC usage has happened among those who have previously smoked. There is a dearth of data on the long-term health implications of EC usage in adolescents and young adults. We do not know whether short-term or intermittent use of EC in youth can lead to negative health outcomes in adulthood, and long-term high-quality studies in well-defined groups are needed. Although vaping has been linked to respiratory symptoms, they tend to be transient and of uncertain significance. This commentary provides up-to-date information so health care providers can give objective and responsible medical advice on EC usage.

Counseling Tobacco Smoke Exposure Reduction Measures in Pediatrics: A Quality Improvement Project

With over 40% of children in the USA exposed to tobacco smoke, the AAP recommends tobacco smoke exposure (TSE) assessment during clinic visits. We aimed to increase the rates of TSE screening and provider counseling regarding TSE reduction using an evidence-based approach.

Financial Insecurity and Food Insecurity among U.S. Children with Secondhand and Thirdhand Smoke Exposure

Objectives: Smokers with financial and food insecurity may find it difficult to quit smoking and reduce their children’s tobacco smoke exposure (TSE). The objective was to examine the associations between child TSE and financial and food insecurity among U.S. school-aged children. Methods: We examined the 2018−2019 National Survey of Children’s Health data on 17,484 children 6−11 years old. Children were categorized into TSE groups: (1) No TSE: did not live with a smoker; (2) thirdhand smoke (THS) exposure alone: lived with a smoker who did not smoke inside the home; or (3) secondhand smoke (SHS) and THS exposure: lived with a smoker who smoked inside the home. We conducted weighted logistic, ordinal, and linear regression analyses to assess the relationships between child TSE status and financial and food insecurity, adjusting for covariates. Results: Overall, 13.1% and 1.8% of children had THS exposure alone and SHS and THS exposure, respectively. Compared to children with no TSE, children with THS exposure alone were at 2.17 increased odds (95% CI = 1.83, 2.58, p < 0.001) and children with SHS and THS exposure were at 2.24 increased odds (95% CI = 1.57, 3.19, p < 0.001) of having financial insecurity. Children with THS exposure alone were at 1.92 increased odds (95% CI = 1.58, 2.33, p < 0.001) and children with SHS and THS exposure were at 2.14 increased odds (95% CI = 1.45, 3.16, p < 0.001) of having food insecurity. Conclusions: Children with TSE are at increased risk of experiencing financial and food insecurity. When developing tobacco interventions, a holistic approach to tobacco control that addresses ways to decrease financial and food hardships may improve outcomes.

Intervening With Smoking Parents of Inpatients to Reduce Exposure: The INSPIRE Randomized Controlled Trial

BACKGROUND

Hospitalized children have high rates of tobacco smoke exposure; parents who smoke may be receptive to interventions during their child's hospitalization.

OBJECTIVE

We tested the efficacy of a smoking cessation intervention for parents of hospitalized children.

METHODS

We conducted a randomized, single-blind clinical trial from 12/14-5/18 at the Children's Hospital Colorado. Hospitalized children who had a parent who smoked tobacco were eligible.

INTERVENTION

Intervention participants received motivational interviewing sessions, 2 weeks of nicotine replacement therapy; both groups received referral to the Quitline Consenting parents completed a questionnaire; urine was collected from the child for measurement of cotinine. Our primary outcome was: 1) increase in reporting "no one is allowed to smoke anywhere" in the home (smoke-free home rule). Additional outcomes included: 2) change in child's cotinine from baseline to 1 year, and 3) parental quitting at 1 year. Data were analyzed using Chi-square and t tests for bivariable data, and multivariable logistic and linear regression.

RESULTS

Of 1641 eligible families approached, 252 were randomized (15%); 149 families had follow-up data at 12 months (59%). In the adjusted analysis, there was no difference between the groups in smoke free home rules, or child cotinine level; in an intention-to-treat analysis, 15% in the intervention group versus 8% of controls reported quit (p=0.07).

CONCLUSIONS

A smoking cessation intervention can be delivered to parents of hospitalized children. While hospitalization provides an opportunity to help parents quit smoking, more efficient and effective engagement strategies are needed to optimize tobacco control success.

Angina Outcomes in Nonsmokers Exposed to Secondhand Smoke: Results from the National Health and Nutrition Examination Survey 2007–2018

Objective  The aim of the study is to examine the relationship between secondhand smoke (SHS) and angina using the National Health and Nutrition Examination Survey database over a 12-year period.

Methods  Self-reported smoking status and cotinine levels were used to identify exposure groups (smokers, nonsmokers, and secondhand smokers), and medical history of angina was also collected via a self-report survey. The association between exposure to SHS and angina was analyzed using odd ratios with 95% confidence intervals calculated using two logistic regression models.

Results  The study found that when aggregating data from all 12 years, secondhand smokers are 42.9% significantly more likely to report having experienced angina, while smokers were 97.7% significantly more likely to report having angina compared with nonsmokers.

Conclusions  This study is the first of its kind to examine data from a national database over a 12-year period to determine an association between SHS and angina outcomes, thus highlighting the importance of reducing SHS exposure to improve cardiovascular health.

Evidence Base for 2022 Updated Recommendations for a Safe Infant Sleeping Environment to Reduce the Risk of Sleep-Related Infant Deaths

Every year in the United States, approximately 3500 infants die of sleep-related infant deaths, including sudden infant death syndrome (SIDS) (International Statistical Classification of Diseases and Related Health Problems 10th Revision [ICD-10] R95), ill-defined deaths (ICD-10 R99), and accidental suffocation and strangulation in bed (ICD-10 W75). After a substantial decline in sleep-related deaths in the 1990s, the overall death rate attributable to sleep-related infant deaths have remained stagnant since 2000, and disparities persist. The triple risk model proposes that SIDS occurs when an infant with intrinsic vulnerability (often manifested by impaired arousal, cardiorespiratory, and/or autonomic responses) undergoes an exogenous trigger event (eg, exposure to an unsafe sleeping environment) during a critical developmental period. The American Academy of Pediatrics recommends a safe sleep environment to reduce the risk of all sleep-related deaths. This includes supine positioning; use of a firm, noninclined sleep surface; room sharing without bed sharing; and avoidance of soft bedding and overheating. Additional recommendations for SIDS risk reduction include human milk feeding; avoidance of exposure to nicotine, alcohol, marijuana, opioids, and illicit drugs; routine immunization; and use of a pacifier. New recommendations are presented regarding noninclined sleep surfaces, short-term emergency sleep locations, use of cardboard boxes as a sleep location, bed sharing, substance use, home cardiorespiratory monitors, and tummy time. In addition, additional information to assist parents, physicians, and nonphysician clinicians in assessing the risk of specific bed-sharing situations is included.

Improving Substance Use Prevention, Assessment, and Treatment Financing to Enhance Equity and Improve Outcomes Among Children, Adolescents, and Young Adults

Access to timely prevention and treatment services remains challenging for many children, adolescents, young adults, and families affected by substance use. The American Academy of Pediatrics recognizes the scope and urgency of this problem and has developed this policy statement for consideration by Congress, federal and state policy makers, and public and private payers. This policy statement updates the 2001 policy statement "Improving Substance Abuse Prevention, Assessment, and Treatment Financing for Children and Adolescents" and provides recommendations for financing substance use prevention, assessment, and treatment of children, adolescents, and young adults.

Sleep-Related Infant Deaths: Updated 2022 Recommendations for Reducing Infant Deaths in the Sleep Environment

Each year in the United States, ∼3500 infants die of sleep-related infant deaths, including sudden infant death syndrome (SIDS) (International Classification of Diseases, 10th Revision [ICD-10] R95), ill-defined deaths (ICD-10 R99), and accidental suffocation and strangulation in bed (ICD-10 W75). After a substantial decline in sleep-related deaths in the 1990s, the overall death rate attributable to sleep-related infant deaths has remained stagnant since 2000, and disparities persist. The triple risk model proposes that SIDS occurs when an infant with intrinsic vulnerability (often manifested by impaired arousal, cardiorespiratory, and/or autonomic responses) undergoes an exogenous trigger event (eg, exposure to an unsafe sleeping environment) during a critical developmental period. The American Academy of Pediatrics recommends a safe sleep environment to reduce the risk of all sleep-related deaths. This includes supine positioning; use of a firm, noninclined sleep surface; room sharing without bed sharing; and avoidance of soft bedding and overheating. Additional recommendations for SIDS risk reduction include human milk feeding; avoidance of exposure to nicotine, alcohol, marijuana, opioids, and illicit drugs; routine immunization; and use of a pacifier. New recommendations are presented regarding noninclined sleep surfaces, short-term emergency sleep locations, use of cardboard boxes as a sleep location, bed sharing, substance use, home cardiorespiratory monitors, and tummy time. Additional information to assist parents, physicians, and nonphysician clinicians in assessing the risk of specific bed-sharing situations is also included. The recommendations and strength of evidence for each recommendation are included in this policy statement. The rationale for these recommendations is discussed in detail in the accompanying technical report.

Technical Report: Breastfeeding and the Use of Human Milk

Breastfeeding and human milk are the normative standards for infant feeding and nutrition. The short- and long-term medical and neurodevelopmental advantages of breastfeeding make breastfeeding or the provision of human milk a public health imperative. The American Academy of Pediatrics (AAP) recommends exclusive breastfeeding for approximately 6 months after birth. Furthermore, the AAP supports continued breastfeeding, along with appropriate complementary foods introduced at about 6 months, as long as mutually desired by mother and child for 2 years or beyond. These recommendations are consistent with those of the World Health Organization (WHO). Medical contraindications to breastfeeding are rare. The AAP recommends that birth hospitals or centers implement maternity care practices shown to improve breastfeeding initiation, duration, and exclusivity. The Centers for Disease Control and Prevention and The Joint Commission monitor breastfeeding practices in United States hospitals. Pediatricians play a critical role in hospitals, their practices, and communities as advocates of breastfeeding and, thus, need to be trained about the benefits of breastfeeding for mothers and children and in managing breastfeeding. Efforts to improve breastfeeding rates must acknowledge existing disparities and the impact of racism in promoting equity in breastfeeding education, support, and services.

Medicaid and moms: the potential impact of extending medicaid coverage to mothers for 1 year after delivery

The American Rescue Plan provides a pathway for states to expand postpartum Medicaid coverage for low-income mothers through 12 months after delivery. Data suggests that extension of post-partum Medicaid coverage should improve access to outpatient health care services, increase healthcare utilization, improve chronic disease management for at-risk mothers, and reduce disparities in care for racial/ethnic groups over-represented in Medicaid. Opportunities to provide increased preventive care for perinatal mood disorders and smoking cessation also exist. Further, this policy may reduce the burden of late maternal mortality. While improved access to contraceptive service postpartum provides a potential mechanism by which birth outcomes may improve, the effect of this policy on NICU admission, low birth weight (LBW) infants, and preterm birth is unknown. We discuss possible birth, infant and maternal health outcomes which may result from this expansion, drawing on data from the 2010 Medicaid Expansion via the Affordable Care Act.

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.

Monthly Motivational Interview Counseling and Nicotine Replacement Therapy for Smoking Parents of Pediatric Patients: A Randomized Controlled Trial

Background

Parental smoking is the dominant source of passive smoke exposure in the pediatric population. The current randomized controlled trial (RCT) study aimed to evaluate the effectiveness of a multi-component smoking reduction intervention in parental smoking reduction and children's environmental tobacco smoke exposure reduction in clinical settings.

Methods

A single-blinded, 6-month randomized controlled trial recruited smoking parents (N = 210) of children who attended the pediatric wards or clinics at the Prince of Wales Hospital. Participants allocated to the intervention group (n = 105) received monthly motivational interviews on smoking reduction with emphasis on health hazards related to children's passive smoke exposure, 8-week nicotine replacement therapy, and referral to smoking cessation service if the parents preferred. The control group (n = 105) received simple verbal advice on smoking cessation. Primary outcomes were parental urine cotinine validated and self-reported ≥50% smoking reduction rates at 6 months.

Results

Smoking parents in the intervention group had significantly more biochemically validated ≥50% smoking reduction than the control: 27.1 vs. 10.0% (OR = 3.34, 95% CI: 1.16-9.62, P = 0.02). The rate of self-reported ≥50% smoking reduction was also significantly higher in the intervention group than the control: 51.9 vs. 20.2% (OR = 4.40, 95% CI: 2.38-8.12, P < 0.001). For secondary outcomes, the rate of parental self-reported smoking cessation was higher in the intervention arm: 10.5 vs. 1.0% (OR = 12.17, 95% CI: 1.54-96.07, P < 0.001), however, no differences were detected in biochemically validated cessation and changes in children's passive smoke exposure between the groups.

Conclusion

Monthly smoking reduction counseling together with nicotine replacement therapy is more effective than simple verbal cessation advice in the smoking reduction for parents of pediatric patients. However, this study did not demonstrate differences in smoking cessation or reduction in children's passive smoke exposure with a 6-month follow-up. Achievement of a smoke-free environment remains challenging.

Disparities in Neighborhood Characteristics among U.S. Children with Secondhand and Thirdhand Tobacco Smoke Exposure

(1) Background: Home tobacco smoke exposure (TSE) and negative neighborhood characteristics adversely affect children’s overall health. The objective was to examine the associations of child TSE status and neighborhood characteristics among U.S. school-aged children. (2) Methods: We conducted a secondary analysis of the 2018–2019 National Survey of Children’s Health (NSCH) data including 17,300 U.S. children ages 6–11 years old. We categorized children’s home TSE status into: (a) no TSE: child did not live with a smoker; (b) thirdhand smoke (THS) exposure alone: child lived with a smoker who did not smoke inside the home; and (c) secondhand smoke (SHS) and THS exposure: child lived with a smoker who smoked inside the home. We conducted a series of weighted linear and logistic regression analyses to assess the associations between child TSE status and neighborhood characteristics, adjusting for covariates. (3) Results: Overall, 13.2% and 1.7% of children were exposed to home THS alone and home SHS and THS, respectively. Compared to children with no TSE, children with home THS exposure alone and children with home SHS and THS exposure had a significantly lower total number of neighborhood amenities and children with SHS and THS exposure had a significantly higher total number of detracting neighborhood elements. (4) Conclusions: Children with TSE demonstrate disparities in the characteristics of the neighborhood in which they live compared to children with no TSE. TSE reduction interventions targeted to children with TSE who live in these neighborhoods are warranted.

How E-cigarettes and vaping can affect asthma in children and adolescents

PURPOSE OF REVIEW

Electronic nicotine delivery systems such as e-cigarettes are commonly felt to be harmless devices when compared to traditional cigarettes. However, an increasing number of studies support the biological plausibility for the potential detrimental effects of vaping on the respiratory mucosa. To date, few human studies have been carried out on adult vapers showing a reduction in lung function testing, especially in those with asthma, whereas the effects of vaping on children and adolescents have not been elucidated so far.

RECENT FINDINGS

Several cross-sectional, national, population-based studies on large groups of adolescents have been carried out showing an association between vape exposure and self-reported asthma diagnosis and/or respiratory symptoms in this age group. The effects of second and third-hand exposure together with those of active and passive exposure in pregnancy, are almost completely unknown.

SUMMARY

This review outlines recent data on the potential effects of vaping on asthma, focusing on vape composition, reported effects on the respiratory mucosa, available data in adolescents, and reasons behind the current vaping epidemic. The evidence so far available both in animals and humans suggests that vaping is not harmless, and its exposure should be limited in children and adolescents, especially when affected by asthma.

Clinical decision support for tobacco screening and counseling parents of pediatric patients: A qualitative analysis of pediatric emergency department and urgent care professionals

Background

Clinical Decision Support Systems (CDSS) embedded into electronic medical records is a best practices approach. However, information is needed on how to incorporate a CDSS to facilitate parental tobacco cessation counseling and reduce child tobacco smoke exposure (TSE) in Pediatric Emergency Department (PED) and Urgent Care (UC) settings. The objective was to explore the barriers and enablers of CDSS use to facilitate child TSE screening and parental tobacco cessation counseling by PED/UC nurses and physicians.

Methods

We conducted 29 semi-structured, focused interviews with nurses (n = 17) and physicians (n = 12) at a children's hospital PED/UC. The interview guide included a brief presentation about the design and components of a prior CDSS tobacco intervention. Participants were asked their opinions about CDSS components and recommendations for adapting and implementing the CDSS tobacco intervention in the PED/UC setting. A thematic framework analysis method was used to code and analyze qualitative data.

Results

Participant mean (± SD) age was 42 (± 10.1) years; the majority were female (82.8%), non-Hispanic white (93.1%), and never tobacco users (86.2%); all were never electronic cigarette users. Four themes emerged: (1) explore optimal timing to complete CDSS screening and counseling during visits; (2) CDSS additional information and feedback needs; (3) perceived enablers to CDSS use, such as the systematic approach; and (4) perceived barriers to CDSS use, such as lack of time and staff.

Conclusions

The CDSS intervention for child TSE screening and parental tobacco cessation during PED/UC visits received endorsements and suggestions for optimal implementation from nurses and physicians.

Screening and counseling for nicotine use in youth with diabetes

OBJECTIVE

To assess current practice patterns and identify knowledge gaps among pediatric endocrinologists in the United States regarding screening and counseling for combustible tobacco and e-cigarette use in youth with diabetes.

INTRODUCTION

Electronic cigarettes (e-cigarettes) are the most used tobacco product among adolescents and may be associated with an increased risk of progression to combustible cigarette smoking, cardiovascular disease, and stroke. Diabetes mellitus is a known risk factor for cardiovascular disease, and nicotine products can increase this risk. We sought to assess current practice patterns and identify knowledge gaps among pediatric endocrinologists in the United States regarding screening and counseling for combustible tobacco and e-cigarette use in youth with diabetes.

RESEARCH DESIGN AND METHODS

We conducted an anonymous, online-based survey of Pediatric Endocrine Society members who provide care to youth with Type 1 or Type 2 diabetes. The survey collected information about provider demographics and smoking habits, knowledge and attitudes regarding screening and counseling for combustible tobacco and e-cigarette use, and current practice patterns.

RESULTS

The survey was completed by 106 individuals of whom 64 reported providing care to youth with diabetes mellitus and ever asking about combustible tobacco or e-cigarette use. The majority of respondents were female, attending providers, and working in academic medical centers. None reported a history of formal training in e-cigarette counseling but recognized the harms of e-cigarette use. Nearly all (98%) who ever screen for nicotine use reported routinely screening for combustible tobacco use, while 18% never screen for e-cigarette use (p < 0.01). Over 80% of respondents reported feeling confident or very confident about discussing the harms of combustible tobacco, compared to 58% reporting the same confidence in discussing harms of e-cigarette use (p < 0.0001). Over 90% of respondents agreed that pediatric endocrinology providers should ask about nicotine use with over half agreeing that counseling reduces the risk of initiating nicotine product use, and 30% reported lack of change with counseling as a barrier to discussing nicotine use. Lack of visit time was the most reported barrier to discussing nicotine use. More providers cited lack of knowledge regarding e-cigarettes compared to combustible tobacco as a barrier to discussing its use.

CONCLUSIONS

Pediatric endocrinology providers recognize the harms of e-cigarette use, but more frequently ask about combustible tobacco use compared to e-cigarette use. This may be related to lower reported confidence and provider knowledge in counseling about e-cigarette use. Increased utilization of existing resources and expanding opportunities for providers to learn more about e-cigarettes may increase provider confidence and comfort in screening and counseling.

Environmental tobacco smoke and carotid intima-media thickness in healthy children and adolescents: a systematic review

Thicker carotid intima-media thickness (CIMT) has been a valid predictor for atherosclerosis development. A significant association between environmental tobacco smoke (ETS) and thickening of CIMT has been demonstrated in adults, whereas such association has scarcely been reviewed in paediatric population. The dominate electronic databases, including MEDLINE (Ovid), PubMed, Embase, CINAHL, Web of Science, Scopus, were searched from inception. Reference lists of retrieved articles were further scanned as to avoid any missing literatures. Newcastle-Ottawa scale was used to assess the quality of the included studies. Qualitative synthesis analyses were performed on the selected studies. 331 articles were retrieved, and 4 were finally selected. All four studies investigated the association between postnatal ETS and CIMT in children, and three of them reported a statistically significant positive association. Three studies investigated the association between prenatal maternal ETS and CIMT, and one of the three found a positive association. Two studies explored the association between postnatal maternal ETS and CIMT, one reported a positive association. Two studies used serum cotinine measurement to quantify ETS and demonstrated potential dose-response relationship with CIMT. ETS exposure may play an independent role in the development of cardiovascular risks in healthy children and adolescents. In the consideration of the great burden of respiratory and cardiovascular diseases, there is an urgent need of effective surveillance for paediatric population's ETS exposure to reduce smoke exposure.

Disparities in dental health issues and oral health care visits in US children with tobacco smoke exposure

BACKGROUND

The objective of the authors was to assess the relationships between tobacco smoke exposure (TSE) and dental health and dental care visits among US children.

METHODS

The authors examined 2018-2019 National Survey of Children's Health data on TSE, dental health, and oral health care visits. Children aged 1 through 11 years (N = 32,214) were categorized into TSE groups: no home TSE (did not live with a smoker), thirdhand smoke (THS) exposure (lived with a smoker who did not smoke inside the home), or secondhand smoke (SHS) and THS exposure (lived with a smoker who smoked inside the home). The authors conducted multivariable logistic regression analyses, adjusting for child age, sex, race or ethnicity, prematurity, caregiver education level, family structure, and federal poverty threshold.

RESULTS

Children with home SHS and THS exposure were at increased odds of having frequent or chronic difficulty with 1 or more oral health problem (adjusted odds ratio [AOR], 1.59; 95% CI, 1.07 to 2.35; P = .022) and carious teeth or caries (AOR, 1.74; 95% CI 1.14 to 2.65; P = .010) than those with no TSE. Compared with children aged 1 through 11 years with no TSE, children with SHS and THS exposure were 2.22 times (95% CI, 1.01 to 4.87; P = .048) more likely to have not received needed oral health care but at decreased odds of having had any kind of oral health care visit (AOR, 0.55; 95% CI, 0.32 to 0.95; P = .032), including a preventive oral health care visit (AOR, 0.60; 95% CI, 0.36 to 0.99; P = .047).

CONCLUSIONS

TSE in children is associated with caries and inadequate oral health care visits.

PRACTICAL IMPLICATIONS

The pediatric dental visit is an opportune time to educate caregivers who smoke about dental health to improve their children's teeth condition and increase oral health care visits.

Quality Improvement Approach to Increase Inpatient Pediatric Secondhand Smoke Exposure Screening

BACKGROUND

Secondhand smoke exposure (SHSe) is highly prevalent among children and has numerous adverse health effects. Consistent screening for SHSe is an essential first step to helping families break the toxic cycle of smoking.

METHODS

With this quality improvement project, we evaluated a SHSe screening and cessation resource distribution protocol in a general pediatrics inpatient unit of a safety-net hospital. Our primary outcome measure was the percent of admissions screened for SHSe, with a goal of increasing our documented rate of SHSe screening from 0% to 70% within 6 months of implementation. Our secondary outcome measure was the percent of those who screened positive for SHSe who were offered smoking cessation resources. Process measures included tracking nurse confidence in screening and compliance with new workflow training. Balancing measures were nurse satisfaction and brevity of screening.

RESULTS

From May 1, 2019, to April 30, 2020, nurses screened 97.2% of the 394 patients admitted to the pediatric unit for SHSe. Of the patients screened, 15.7% were exposed to cigarettes or other tobacco products, 5.6% to e-cigarettes, and 6.5% to marijuana. Nurses documented offering "Quit Kits" with cessation materials to 45 caregivers (72.6% of positive screen results) and offering 33 referrals to the California Smokers' Helpline (53.2% of positive screen results).

CONCLUSION

In this project, we successfully implemented a screening protocol for SHSe to tobacco, e-cigarettes, and marijuana and a workflow for cessation resource distribution in an inpatient pediatric setting that far exceeded goals. Requiring minimal maintenance and using just a simple paper-based format, the workflow could be adopted at other institutions.

Tobacco Cessation Behaviors Among U.S. Middle and High School Students, 2020

PURPOSE

The landscape of youth tobacco product use has changed dramatically in recent years; however, little is known about current youth cessation behaviors. This study aims to assess prevalence and correlates of quit intentions and past-year quit attempts among U.S. middle and high school students who report current use of any tobacco product, cigarettes, and e-cigarettes.

METHODS

Data came from the 2020 National Youth Tobacco Survey, a nationally representative cross-sectional school-based survey of students in grades 6-12. Weighed prevalence estimates of quit intentions and past-year quit attempts among users of any tobacco product, cigarettes, and e-cigarettes are presented. Multivariable-adjusted logistic regression with predictive marginals was used to assess sociodemographic correlates of quit intentions and quit attempts for each tobacco product user group.

RESULTS

Quit intentions were reported by 62.5% of current users of any tobacco product, 68.1% of cigarette smokers, and 63.9% of e-cigarette users. Similarly, past-year quit attempts were reported by 65.4% of current users of any tobacco product, 65.8% of cigarettes smokers, and 67.4% for e-cigarette users. Harm perceptions toward tobacco, nicotine dependency, and the use of ≥2 tobacco products were significantly correlated with quit intentions, quit attempts, or both among different tobacco product user groups.

CONCLUSIONS

Most students who use tobacco products want to quit and have attempted to do so. Development of youth-focused cessation interventions, particularly those addressing the most commonly used products, could potentially accelerate progress in a comprehensive approach to youth tobacco prevention and control.

Parental Knowledge, Attitude, and Practice on Tobacco Use, Smoking Cessation, and Children's Environmental Tobacco Smoke Exposure

Background: Environmental tobacco smoke (ETS) exposure in children ranks one of the major public health problems in our time. Poor parental knowledge, attitude, and practice (KAP) on ETS often contribute to worse exposure of the kids. Thus, we aimed to document parental KAP regarding tobacco use, smoking cessation and children's ETS exposure, and to analyse how knowledge and attitude relate to practice.

Methods: Self-administered KAP questionnaires were distributed to smoking parents recruited from the pediatric unit at the Prince of Wales Hospital, which provides pediatric service to a population of 1.2 million in Hong Kong. The 60-item questionnaire had a range of 0–38 for knowledge, 0–44 for attitude, and 0–40 for practice. Descriptive analyses were performed for KAP response, regression analyses were performed for the exploration of associations and identification of predictive indicators.

Results: 145 smoking parents (mean age: 38.0 ± 6.7 yrs.; male: 85.5%) were included. Less than half (39.3%) of them reported a smoke-free policy at home. Among those parents who had private cars, less than half (45.2%) of them had smoke-free policy in their car that they never smoked in the car. Only 25.5% of the participants correctly answered ≥70% of the knowledge questions, and 11.8 % of the participants gave favorable responses to ≥70% of the attitude questions. The total knowledge and the total attitudes score were positively associated (r = 0.49, 95% CI: 0.35–0.79, p < 0.001), yet they were only modestly correlated with parental practice on children's ETS exposure. By multivariate regressions, potential predictive factors for more favorable parental KAP included higher household income, lower parental nicotine dependence level and breastfeeding practice.

Conclusions: Parental KAP related to tobacco use and children's ETS exposure needs improvement to address the significant gap between recommended and actual practice. The weak association between knowledge and practice suggested that parental education alone is not adequate to combat ETS exposure in children.

Are marijuana-using caregivers being asked about their marijuana use by their child’s pediatrician?

Our objective was to identify the percentage of marijuana-using caregivers who have been asked about their marijuana use by their child’s pediatrician. Data was collected from a cross-sectional, convenience sample survey study of 1500 caregivers presenting with their children to the Children’s Hospital Colorado Pediatric Emergency Department between December 2015 and July 2017. Of the 1500 caregivers surveyed, 167 (11%) reported using marijuana. When asked if their child’s pediatrician had ever inquired/counseled about caregiver marijuana use, 165 marijuana-using caregivers responded; 149 caregivers (90.3%) reported “no,” 9 caregivers (5.4%) reported “yes,” and 7 caregivers (4.2%) reported “unsure.” We concluded that of marijuana-using caregivers, only a small percentage indicated their child’s pediatrician had inquired about caregiver marijuana use. This suggests pediatricians are not engaging caregivers about marijuana use and the subsequent secondhand marijuana smoke exposure for children. The continued rise of marijuana use among parents makes this research of public health importance.

Smoking habit in parents and exposure to environmental tobacco smoke in elementary school children of Milan

INTRODUCTION

Children with smoking parents are potentially exposed to Environmental Tobacco Smoke (ETS). The aims of this study were: 1) to assess ETS exposure in Milan schoolchildren, by measuring urinary cotinine (COT-U), 2) to compare the parents' perception of children ETS exposure, with the actual ETS exposure measured by COT-U, 3) to explore the factors influencing COT-U, including smoking bans at home, the season, and children characteristics.

METHODS

One-hundred school children (7-11 years) and their parents were recruited for the study in Spring 2018 (n = 81) and in Winter 2019 (n = 94), 75 children participated to both campaigns, for a sum of 175 observations. A questionnaire was submitted to parents to collect information about smoking habits in the house. COT-U was measured by LC-MS/MS in spot urine sample collected in the morning from children.

RESULTS

Detectable COT-U levels were found in 42% and 57% of children, in spring and winter, in contrast with 17% and 13% of parents acknowledging ETS exposure. Children living with smokers or e-cigarette users (vapers) (30% of the participants) had higher COT-U levels than children not living with smokers or vapers (median 0.67, 0.46, and <0.1 μg/L in spring, and 0.98, 0.85, and 0.11 μg/L in winter, respectively). Increasingly higher COT-U levels were observed in children living in homes where smoking was completely banned, allowed in the external parts of the home, or allowed in some rooms. The multiple regression analysis confirmed the positive significant effect of living with smokers, a partial smoking ban and absence of smoking ban at home, the winter season, and BMI as determinants of COT-U.

CONCLUSION

ETS exposure resulted in measurable urinary cotinine in children. Smoking parents underestimate exposure to ETS of their children. Living with smokers is a determinant of COT-U, only slightly mitigated by adopting partial smoking ban.

Interconception Care and Safe Sleep: Adapting the IMPLICIT Toolkit for Pediatrics

BACKGROUND

A woman's health in the interconception period has an impact on birth outcomes. Pediatric visits offer a unique opportunity to provide interconception care (ICC). Our aim was to screen and provide interconception and safe sleep screening, counseling, and interventions for 50% of caregivers of children <2 years of age in a pediatric medical setting.

METHODS

Two pediatric clinics implemented the March of Dimes' Interventions to Minimize Preterm and Low Birth Weight Infants Through Continuous Improvement Techniques (IMPLICIT) toolkit, in addition to standardized safe sleep assessments. A quality improvement learning collaborative was formed with a local "infant mortality champion" leading quality improvement efforts. Monthly webinars with the clinic teams reviewed project successes and challenges. Framework for Reporting Adaptations and Modifications was used to document adaptations.

RESULTS

For each individual IMPLICIT domain, clinics screened and provided needed interventions for ICC and safe sleep in >50% of eligible encounters. Over the course of the quality improvement learning collaborative, the number of caregivers screened for at least 4 of the 5 IMPLICIT domains increased from 0% to 95%.

CONCLUSIONS

To successfully implement the IMPLICIT toolkit in pediatrics, adaptations were made to the existing model, which had previously been used in family medicine clinics. Pediatricians should consider providing ICC as an innovative way to impact infant mortality rates in their community. Framework for Reporting Adaptations and Modifications can be used to systematically describe the adaptations needed to improve the fit of IMPLICIT in the pediatric clinic, understand the process of change and potential application to local context.

Regional comparison of self-reported late pregnancy cigarette smoking to mass spectrometry analysis

OBJECTIVE

To report a more accurate prevalence estimate of late pregnancy nicotine exposures.

STUDY DESIGN

A cross-sectional study during a 2-month period in 2019. Participants were women delivering in any of the six county maternity hospitals who consented to universal drug testing at the time of delivery as part of routine hospital admission.

RESULTS

Of 2531 tested samples, 18.7% tested positive for high levels of cotinine indicating primary smoking or other primary use of tobacco products. Together, 33.0% of the study population tested positive for nicotine exposure during late pregnancy compared to vital records which reported 8.2% cigarette smoking during the third trimester of pregnancy and 10.5% cigarette smoking at any time during pregnancy through maternal self-report.

CONCLUSION

Captured vital birth smoking measures vastly underreport actual primary exposures to nicotine products. Vital birth data also fail to capture secondhand exposures which constitute a significant proportion of the population.

Environmental Factors

The acute respiratory distress syndrome (ARDS) remains a major cause of morbidity and mortality in the intensive care unit. Improving outcomes depends on not only evidence-based care once ARDS has already developed but also preventing ARDS incidence. Several environmental exposures have now been shown to increase the risk of ARDS and related adverse outcomes. How environmental factors impact the risk of developing ARDS is a growing and important field of research that should inform the care of individual patients as well as public health policy.
