Home smoking policies in urban households with children and smokers

Protecting Young Lives: A Systematic Review of the Impact of Secondhand Smoke Exposure and Legislative Measures on Children's Health

Each year, a substantial number of global deaths are attributed to secondhand smoke (SHS) exposure, with children representing a significant proportion of these fatalities. This systematic review evaluates the effects of passive smoking, or SHS, on children's health outcomes, focusing on respiratory conditions, behavioral issues, cognitive impairment, growth retardation, and immune system effects. A comprehensive literature search was conducted from July 5 to July 18, 2024, across multiple databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. Following the set inclusion and exclusion guidelines, 12 studies were chosen for the review, and their quality was measured using the Newcastle-Ottawa Scale. The findings indicate a strong association between SHS exposure and adverse health outcomes in children, including increased rates of asthma, low birth weight, and behavioral problems. Additionally, smoke-free legislation appears to mitigate some of these harmful effects, though results vary across different regions and populations. The review underscores the urgent need for effective smoking cessation strategies and improved healthcare communication to protect children from the dangers of passive smoking.

Responsibility, normalisation and negotiations of harm: E-cigarette users' opinions and experiences of vaping around children

BACKGROUND

Concern about youth uptake of vaping is widespread. Regulation and education campaigns aim to protect children from initiating use, yet it is likely that children will be primarily influenced by the behaviour of people in their immediate environment. This is the first known study exploring e-cigarette users' views and reported experiences of vaping around children.

METHODS

Following informed consent, semi-structured qualitative interviews were conducted with 40 adults who had attempted to give up smoking by vaping. Participants were recruited from England as part of a wider study into e-cigarette use trajectories and smoking relapse (ECtra study). Data were extracted from 28 interviews where participants had spontaneously discussed vaping around children. Extracted data were analysed thematically and situated in previous analysis of vaping identity which distinguished between recreational and medicinal vapers.

RESULTS

Vaping behaviour around children was in part a habituated replication of smoking norms but also guided by broad vaping identity; recreational users were more permissive and medicinal users more secretive. Vaping in the home appeared to be determined by caregivers' need to reconcile vaping behaviour so that it was congruent with parental identity as a responsible caregiver. Participant perspectives reflected existing moral discourses applied to e-cigarettes around the use of "harm reduction for smokers" and "potential for youth harm".

CONCLUSION

Vaping is likely to be role modelled within the community and home despite attempts by e-cigarette users to conceal the behaviour. The ambivalent contextualisation of e-cigarettes means that e-cigarette users may lack a clear narrative to draw on when discussing vaping with children. Public health guidance for vaping around children could be helpful, but to be most effective, should take into consideration users' vaping identity.

Barriers and Facilitators of Asthma Management as Experienced by African American Caregivers of Children with Asthma: An Integrative Review

INTRODUCTION

African American children with asthma demonstrate significant health disparities and poor health outcomes. Understanding the burdens faced by parents and caregivers of children with asthma may be helpful to develop future interventions to address this disparity.

PURPOSE

The purpose of this integrative review was to reveal the barriers and facilitators of child asthma management experienced by African American caregivers.

METHOD

Whittemore and Knafl's (2005) method of integrative review was used to review 40 articles. The integrative review involved appraising the quality of the literature, conducting a thematic analysis, and evaluating the barriers and facilitators of pediatric asthma management experienced by African American caregivers.

RESULTS

Barriers and facilitators were identified as themes. Barriers included caregiver burdens, and lack of home and neighborhood safety. Facilitators were family and community support, education and empowerment, and culturally competent healthcare providers.

DISCUSSION

To improve the care of African American children with asthma, nurses should work to engage, communicate, and foster trust with families. Nurses should assess and address the family caregivers' burdens while emphasizing support systems.

[Exposure to second-hand smoke in school adolescents from Tunja (Colombia), 2017]

INTRODUCTION

Adolescents exposed to second-hand smoke have a higher risk of morbidity. This is one of the main preventable public health problems in Latin America.

OBJECTIVE

To determine the prevalence and sociodemographic factors associated with exposure to second-hand tobacco smoke at home and out-of-home, in school adolescents from Tunja-Colombia.

METHODOLOGY

This cross-sectional study included 1100 school students, aged between 11 and 19 years. The information was obtained using a self-administered and totally anonymous questionnaire. For the analysis, the proportions of everyday exposure and the mean number of days of exposure to second-hand smoke during a regular week were estimated. For the associations, ordinal logistic regression and negative binomial regression models were performed.

RESULTS

The average age of the participants was 14.5 years, with the majority (59%) being female. As regards second-hand tobacco smoke exposure at home, an everyday prevalence of 4.9% was found, from 1 to 6 days of 14.7%, with a mean exposure of 0.7 days (SD 1.7). Additionally, there was a higher prevalence of exposure to second-hand smoke out-of-home: every day 8%, from 1 to 6 days of 34.1%, with a mean exposure of 1.5 days (SD 2.2).

CONCLUSION

The prevalence of exposure to second-hand smoke in adolescents of Tunja was high. Interventions at school and family level are recommended to counteract this problem.

Provider Counseling About Secondhand Smoke Exposure for Urban Children With Persistent or Poorly Controlled Asthma

Urban children continue to be exposed to secondhand smoke (SHS), and this is particularly concerning for children with asthma. The objective of this study is to describe SHS exposure among urban children with asthma and assess SHS counseling delivered at primary care visits. We interviewed caregivers of 318 children (2-12 years) with persistent asthma at the time of a health care visit and reviewed medical records. We found that one third (32%) of children lived with a caregiver who smoked and that 15% lived with other smokers. Children whose caregivers smoked had the lowest prevalence of home smoking bans compared with homes with other smokers and no smokers (65% vs. 72% vs. 95%, respectively). Overall, 67% of caregivers received some SHS counseling. Providers most often counseled caregiver smokers; counseling occurred less frequently for caregivers in homes with other or no smokers. Further efforts to improve provider SHS counseling for all children with asthma are needed.

Prevalence and Indicators of Household Smoking Bans Among American Indians

More than 58 million nonsmokers in the U.S. encounter secondhand smoke that leads to tobacco-related diseases and deaths every year, making voluntary household smoking bans an important public health goal. American Indians/Alaska Natives are rarely included in research related to household smoking bans. Further, most studies dichotomize household smoking bans into complete bans versus partial/no bans, rendering it impossible to determine if partial and no bans are associated with different or similar risk factors. Using the 2014 Cherokee Nation American Indian Adult Tobacco Survey, our study sought to identify prevalence of household smoking bans, their extent, and their correlates in an American Indian population. This cross-sectional analysis used multinomial logistic regression to determine correlates of complete, partial, and no household smoking bans. Results indicated that approximately 84% of Cherokee households have a complete ban. Younger age, female gender, higher education, higher household income, respondent's nonsmoking status, good health, better awareness of harms related to secondhand smoke, visits with a healthcare provider within the past year, and children in the home were positively and significantly associated with complete household smoking bans. Additionally, there were notable differences between correlates related to partial bans and no bans. These results provide insight for the development of more appropriate interventions for American Indian households that do not have a complete household smoking ban.

Medication use, sleep, and caregiver smoking status among urban children with asthma

OBJECTIVE

Children living in urban settings from low-income, minority families are at a high risk for experiencing asthma morbidity. Environmental tobacco smoke (ETS, i.e., secondhand) exposure, typically from caregiver smoking, has been associated with increased quick-relief medication use and child nocturnal awakenings due to increased asthma symptoms as well as worse sleep quality in children with asthma. This study investigated the moderating role of caregiver smoking status on the association between quick-relief medication use and child's sleep quality in urban children with persistent asthma.

METHODS

Fifty-four urban children with persistent asthma and their primary caregivers completed a baseline research session. Caregivers then completed ecological momentary assessment surveys via smartphones twice daily for two weeks in which smoking behaviors, child quick-relief medication use, and child's sleep quality were assessed.

RESULTS

Twenty caregivers (37%) reported smoking at least one day across the two-week period. The caregiver smoking status significantly moderated the association between quick-relief medication use and child's sleep quality after controlling for child age and monthly household income. The caregiver smoking status exacerbated the association between quick-relief medication use and child's sleep quality, such that more medication usage was associated with worse sleep quality.

CONCLUSIONS

Findings suggest that in urban families with a caregiver who smokes, more daily quick-relief medication use may put children at an increased risk for worse sleep quality. The effects of ETS exposure on child's sleep quality in addition to child asthma symptoms should be an integral part of discussions between pediatric healthcare providers and families of children with asthma.

Urinary cotinine concentrations in preschool children showed positive associations with smoking fathers

AIM

This study aimed to test the association between fathers' smoking behaviour and urinary cotinine levels among preschool children exposed to environmental tobacco smoke (ETS). Possible factors influencing this association were also explored.

METHODS

We recruited 368 smoking fathers with children aged five to six from five preschools in the city of Changsha, China. Urine samples were collected from the children, and the fathers were interviewed face-to-face. We adjusted for potential confounding factors with linear regression models.

RESULTS

The geometric mean of the cotinine concentration in the children's urine was 3.94 ng/mL (95% confidence interval 3.71-4.22). In multivariate analyses, the important predictors of urinary cotinine levels among children, after adjusted confounding factors, were the number of cigarettes smoked in front of the children at home per day (B = 0.414, p < 0.001), the number of cigarettes smoked by the father in front of the children at home (B = 0.105, p < 0.001) and the mean duration of the children's exposure to ETS at home (B = 0.111; p = 0.046).

CONCLUSION

Urinary cotinine concentrations of children exposed to ETS at home were positively associated with smoking fathers and smoking behaviours and the mean duration of ETS exposure at home. Targeted interventions are urgently needed to reduce children's exposure.

Associations Between Caregiver Health Literacy and Preschool Children's Secondhand Smoke Exposure

OBJECTIVE

Examine the associations between caregiver health literacy (HL) and smoking-related outcome expectancies, implementation of home/car smoking bans (H/CSBs), and child secondhand smoke exposure (SHSe).

METHODS

Caregivers of Head Start children residing with a smoker(s) completed measures assessing HL, outcome expectancies, and H/CSB implementation. Biomarkers of child SHSe included home air nicotine monitors and child salivary cotinine.

RESULTS

Caregivers with lower HL had higher levels of home air nicotine and child salivary cotinine in the full sample and among smokers. After controlling for child age and number of smokers in the home, lower HL was associated with higher endorsement of negative smoking expectancies in the full sample and in smokers. HL was not associated with H/CSB implementation across groups.

CONCLUSIONS

Caregiver HL is associated with child SHSe and is important in shaping smoking-related beliefs. HL is not directly related to adoption of SHSe-reduction behaviors such as H/CSBs.

Urinary cotinine levels and environmental tobacco smoke in mothers and children of Romania, Portugal and Poland within the European human biomonitoring pilot study

The aim of this study was to explore data from the DEMOCOPHES study population for Romania, Portugal and Poland, in order to assess smoking patterns and the extent of ETS exposure and compare the national study samples with reference to the respective anti-smoking laws. The subset of the DEMOCOPHES study sample consisted of 360 children and their mothers (120 in each of the three countries - Romania (RO), Portugal (PT) and Poland (PL). Smoking was assessed using a detailed questionnaire for the participants, which addresses both active and passive smoking. This assessment uses exposure-relevant questionnaire data, in particular on the home environment and residence, socio-demographic characteristics, lifestyle such as nutrition, smoking behavior, other exposure-relevant behavior and occupational history, as well as urinary cotinine and creatinine measurements. We performed general statistical analysis and innovative receiver operating characteristic (ROC) curve analyses. Smoking prevalence as evaluated by the questionnaire was generally high, and higher than official statistics, which suggests some under-reporting in the countries, particularly in Romania. Urinary cotinine levels provided biochemical confirmation of the high and similar smoking prevalence for the three countries. Concerning ETS exposure, Romania presented significantly higher levels, for children as well as for non-smoking mothers, with Portugal showing significantly lower levels. Compared to non-smoking mothers, the children showed relatively higher ETS exposure levels in all three countries. The established country-specific optimal cut-off values in urinary cotinine to distinguish smokers from non-smokers vary more than those to discriminate ETS exposure extent in non-smoking mothers and children. Although different between countries, these values are a valuable output to monitor effectiveness of both national antismoking laws and educational programs in the three countries. The findings of this study point to the urgent need for stronger, more effective and well enforced smoke-free legislation in the three countries.

Relationship between caregivers' smoking at home and urinary levels of cotinine in children

Objective: To assess the impact of different smoking behaviors of caregivers on environmental tobacco smoke (ETS) exposure in children aged 5–6 years in Changsha, China. Methods: We conducted a cross-sectional, random digit-dial telephone survey of caregivers (n = 543) between August and October 2013. Caregivers’ smoking behaviors were collected by a questionnaire. Exposure assessment was based upon determination of urinary cotinine levels in children employing gas chromatography–triple quadrupole mass spectrometry (GC-MS/MS). Results: In children not living with a smoker, children living with one smoker, and children living with more than one smoker at home, median urinary cotinine concentrations (ng/mL) were 0.72, 2.97, and 4.46, respectively. For children living with one smoker, median urinary cotinine levels of children exposed to ETS were associated with caregiver smoking behaviors, i.e., if a caregiver consumed more cigarettes (>20 compared with ≤10; 7.73 versus 2.29 ng/mL, respectively). Conclusions: The magnitude of ETS exposure in children is correlated with the smoking behaviors of the caregiver. Counseling for smoking cessation and educational interventions are needed urgently for smoking caregivers to increase their awareness about ETS exposure and to encourage smoking cessation at home or to take precautions to protect children’s health.

Predictors of children's secondhand smoke exposure at home: a systematic review and narrative synthesis of the evidence

BACKGROUND

Children's exposure to secondhand smoke (SHS) has been causally linked to a number of childhood morbidities and mortalities. Over 50% of UK children whose parents are smokers are regularly exposed to SHS at home. No previous review has identified the factors associated with children's SHS exposure in the home.

AIM

To identify by systematic review, the factors which are associated with children's SHS exposure in the home, determined by parent or child reports and/or biochemically validated measures including cotinine, carbon monoxide or home air particulate matter.

METHODS

Electronic searches of MEDLINE, EMBASE, PsychINFO, CINAHL and Web of Knowledge to July 2014, and hand searches of reference lists from publications included in the review were conducted.

FINDINGS

Forty one studies were included in the review. Parental smoking, low socioeconomic status and being less educated were all frequently and consistently found to be independently associated with children's SHS exposure in the home. Children whose parents held more negative attitudes towards SHS were less likely to be exposed. Associations were strongest for parental cigarette smoking status; compared to children of non-smokers, those whose mothers or both parents smoked were between two and 13 times more likely to be exposed to SHS.

CONCLUSION

Multiple factors are associated with child SHS exposure in the home; the best way to reduce child SHS exposure in the home is for smoking parents to quit. If parents are unable or unwilling to stop smoking, they should instigate smoke-free homes. Interventions targeted towards the socially disadvantaged parents aiming to change attitudes to smoking in the presence of children and providing practical support to help parents smoke outside the home may be beneficial.
