Impact of public smoking bans on children's exposure to tobacco smoke at home: a systematic review and meta-analysis.

ABSTRACT: BACKROUND:Meta-analysis of the impact of public smoking bans on children's exposure to secondhand smoke (SHS) exposure at home. METHODS:The electronic databases of PubMed, Web of Science, PsycINFo, ASSIA, CINAHL were searched. German public health journals not captured by these databases and grey literature were considered in addition. Studies were included when they reported children's SHS exposure at home in relation to smoke-free legislation by measuring exposure before and after the introduction of a public smoking ban. Studies had to provide results on exposure prevalences of children aged below 18 years. Language of publications was restricted to German and English. Details of the included studies (n?=?15) were extracted by one author and checked for accuracy by a second author. Given the exposure prevalences before and after the introduction of a smoke-free legislation, a random-effects meta-analysis of relative risks (RR) was conducted. Results were presented in a forest plot. RESULTS:Meta-analysis showed that the overall effect was a decreased exposure to SHS in the children's homes after introduction of a public smoking ban (RR?=?0.72; 95% CI?=?0.62-0.83). Only two of the 15 studies indicated an increased exposure. Sensitivity analyses considering the type of smoke-free legislation, children's age group and study quality did not substantially alter the result. CONCLUSION:The assumption of a displacement of smoking into homes with children due to smoke-free legislation in public places could not be confirmed. Additional research is needed to analyse long-term trends.

Project description: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.

Project description:IntroductionTobacco smoke exposure (TSE) has considerable adverse respiratory health impact among children. Smoke-free policies covering enclosed public places are known to reduce child TSE and benefit child health. An increasing number of jurisdictions are now expanding smoke-free policies to also cover outdoor areas and/or (semi)private spaces (indoor and/or outdoor). We aim to systematically review the evidence on the impact of these 'novel smoke-free policies' on children's TSE and respiratory health.Methods and analysis13 electronic databases will be searched by two independent reviewers for eligible studies. We will consult experts from the field and hand-search references and citations to identify additional published and unpublished studies. Study designs recommended by the Cochrane Effective Practice and Organisation of Care (EPOC) group are eligible, without restrictions on the observational period, publication date or language. Our primary outcomes are: self-reported or parental-reported TSE in places covered by the policy; unplanned hospital attendance for wheezing/asthma and unplanned hospital attendance for respiratory infections. We will assess risk of bias of individual studies following the EPOC or Risk Of Bias In Non-randomised Studies of Interventions tool, as appropriate. We will conduct separate random effects meta-analyses for smoke-free policies covering (1) indoor private places, (2) indoor semiprivate places, (3) outdoor (semi)private places and (4) outdoor public places. We will assess whether the policies were associated with changes in TSE in other locations (eg, displacement). Subgroup analyses will be conducted based on country income classification (ie, high, middle or low income) and by socioeconomic status. Sensitivity analyses will be undertaken via broadening our study design eligibility criteria (ie, including non-EPOC designs) or via excluding studies with a high risk of bias. This review will inform policymakers regarding the implementation of extended smoke-free policies to safeguard children's health.Ethics and disseminationEthical approval is not required. Findings will be disseminated to academics and the general public.Prospero registration numberCRD42020190563.
