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

ABSTRACT:

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.

Project description:BackgroundExposure to secondhand tobacco smoke (SHS) and child maltreatment are preventable threats to child health. Few evidence-based interventions target both SHS and child maltreatment risk. The purpose of this paper is to describe the systematic braiding process of two evidence-based programs to address child SHS in the home and maltreatment perpetration risk, and present results from the formative work and pilot study.MethodsThe first 4 steps of the systematic braiding process were completed, including the following: (1) the identification of core elements of both programs, (2) the development of an initial draft of the braided curriculum (Smoke-Free Home SafeCare - SFH-SC), (3) an acceptability and feasibility pilot of SFH-SC with caregivers of young children who reported a smoker living in the home (N = 8), and (4) feedback collection on the braided curriculum from SafeCare Providers (N = 9).ResultsExperts identified common pedagogical and theoretical underpinnings for the two programs and braided Smoke-Free Homes: Some Things Are Better Outside into two SafeCare modules. Caregiver feedback from the pilot demonstrated that participants were engaged with SFH-SC and felt supported and comfortable discussing SHS intervention content with the SFH-SC Provider. Caregiver self-reports indicated a slight increase in smoke-free home rules from baseline to follow-up and a notable reduction in parent stress on the Parent Stress Index of 5.9 points (SD = 10.2). SafeCare Provider feedback following intensive review of the curriculum indicated high feasibility for SFH-SC delivery.ConclusionsParent and Provider findings suggest SFH-SC is a viable intervention that has potential to reduce the public health impact of SHS and child maltreatment for at-risk families.ProtocolThe protocol for the pilot is not published elsewhere; however, the full protocol for the hybrid trial can be found here: https://clinicaltrials.gov/ct2/show/NCT05000632 .Trial registrationNCT, NCT05000632. Registered 14 July 2021, there is not a separate registration number for the pilot.

Project description:BackgroundThe association between exposure to secondhand smoke (SHS) during pregnancy and a child's neurodevelopment has not been established yet. We explored the association between prenatal exposure to SHS and neurodevelopment at 24 months of age considering genetic polymorphism and breastfeeding in 720 mothers and their offspring enrolled in the Korean multicenter birth cohort study (Mothers and Children Environmental Health, MOCEH).MethodsWe quantified urine cotinine concentrations in mothers once from 12th to 20th gestational weeks and excluded those whose urine cotinine levels exceeded 42.7 ng/ml to represent SHS exposure in early pregnancy. Mental developmental index (MDI) and psychomotor developmental index (PDI) values were measured using the Korean version of the Bayley Scales of Infant Development II (K-BSID-II) at 24 months of age. A general linear model was used to assess the relationship between maternal urinary cotinine level and neurodevelopment.ResultsMDI scores were inversely associated with cotinine [β = - 2.73; 95% confidence interval (CI): - 5.32 to - 0.15] in children whose mothers had early pregnancy urinary cotinine levels >1.90 ng/ml. No association was evident in children whose mothers had cotinine levels ≤1.90 ng/ml. This negative association was more pronounced in children whose mothers had both Glutathione S-transferases mu 1 (GSTM1) and theta 1 (GSTT1) null type [β = - 5.78; 95% CI: -10.69 to - 0.87], but not in children whose mothers had any present type of GSTM1/GSTT1 [β = - 1.64; 95% CI: -4.79 to 1.52]. The association was no longer significant when children received breast milk exclusively for up to 6 months [β = - 0.24; 95% CI: -4.69 to 4.20] compared to others [β = - 3.75; 95% CI: -7.51 to 0.00]. No significant association was found for PDI.ConclusionsMaternal exposure to SHS during pregnancy may result in delayed MDI in early childhood. This effect might be modified by genetic polymorphism and breastfeeding behavior.

Project description:INTRODUCTION:Although many workers are protected from exposure to secondhand tobacco smoke (SHS), home health and community care workers enter domestic settings where SHS is commonly present. Little is known about the extent of SHS exposure among this occupational group. METHODS:A rapid review to examine the literature on home health and community care workers' exposure to SHS at work and identify research gaps. Systematic searches combining terms for SHS exposure (eg, "tobacco smoke pollution") with terms for home health and care workers, patients and settings (eg, "home health nursing") were run in CINAHL and Medline (with no date or language limitations). Web site and backward-forward citation searches identified further papers for narrative review. RESULTS:Twenty relevant publications covering seventeen studies considered home health or community care workers' exposure to SHS either solely or as part of an assessment of other workplace hazards. Eight studies provided data on either the proportion of home care workers exposed to SHS or the frequency of exposure to SHS. No studies provided quantification of SHS concentrations experienced by this group of workers. CONCLUSIONS:Exposure to SHS is likely to be common for workers who enter private homes to provide care. There is a need for research to understand the number of workers exposed to SHS, and the frequency, duration, and intensity of the exposure. Guidance should be developed to balance the rights and responsibilities of those requiring care alongside the need to prevent the harmful effects of SHS to workers providing care in domestic settings. IMPLICATIONS:Very little is known about home health and community care workers' exposure to SHS. There is a need for research to quantify how many workers are exposed, how often and for how long exposure occurs, and the concentrations of SHS experienced. In many countries, home health care workers may be one of the largest working groups that experience exposure to SHS as part of their employment. The public health community needs to engage in a debate about how home health care workers can be best protected from SHS.
