Parental psychosocial predictors of secondhand smoke exposure (SHSe) for children with cancer

Primary Care Healthcare Professionals' Knowledge, Attitudes, and Practices Towards Promoting the Reduction of Children's Secondhand Smoke Exposure: A Mixed-Methods Review and Synthesis

INTRODUCTION

Secondhand smoke exposure (SHSe) leads to increased mortality and morbidity. Primary care healthcare professionals (HCPs) are well placed to support patients to reduce SHSe. This paper explores HCPs': (1) knowledge around SHSe; (2) current practices to promote SHSe reduction; (3) beliefs and experiences regarding delivering interventions to reduce SHSe; and (4) identified factors that influence the delivery of SHSe-related interventions.

METHODS

Six electronic databases were searched for relevant literature published January 1980-February 2016. 17 quantitative and 3 qualitative studies were included in this mixed-methods review. Data synthesis followed the method outlined by the Joanna Briggs Institute. This segregated approach involved independent syntheses of the quantitative and qualitative data followed by an overall mixed-methods synthesis.

RESULTS

Primary care HCPs had a basic understanding of the risks associated with SHSe but required training to help them intervene. It was more common for HCPs to ask about SHSe or provide advice than to act to facilitate SHSe reduction. SHSe was viewed as an issue of high importance and considered relevant to the role of the primary care HCPs. However, barriers such as the priority given to the issue and the desire to protect the professional relationship with patients prevented HCPs from intervening around SHSe.

CONCLUSIONS

Primary care HCPs require training, guidance, and support to enable them to intervene and support patients to effectively reduce SHSe.

IMPLICATIONS

This review used rigorous methods to explore the current, global literature on how children's exposure to secondhand smoke is being addressed in primary care settings. The review findings highlight healthcare professionals' need for further training and support, which would enable them to better translate their knowledge of the risks associated with secondhand smoke exposure into actual clinical practices. The review identified a lack of practical action taken to address secondhand smoke exposure, even once it has been identified as an issue.

Family Beliefs and Behaviors About Smoking and Young Children's Secondhand Smoke Exposure

INTRODUCTION

Home smoking bans (HSBs) reduce children's secondhand smoke exposure (SHSe), a contributor to health disparities. General psychosocial characteristics and SHSe beliefs and behaviors within the family may relate to HSB existence. This study's aim was to identify general psychosocial characteristics and SHSe beliefs associated with HSB presence and lower SHSe among children living with a smoker.

METHODS

Caregivers (n = 269) of Head Start preschool students (age 1-6 years) living with a smoker reported on HSBs, caregiver depressive symptoms and stress, family routines, SHSe beliefs, and household smoking characteristics. SHSe biomarkers included air nicotine in 2 areas of the home and child salivary cotinine.

RESULTS

One-quarter of families reported complete HSBs, and HSBs were more common among nonsmoking (37%) versus smoking caregivers (21%; p < .01). Perceived importance of HSBs differed between nonsmoking (9.7±1.0) versus smoking caregivers (9.1±2.0; p < .01). Smoking caregivers, more smokers in the home, and lower self-efficacy and intent to implement an HSB were consistently associated with lower likelihood of HSB existence and children's higher SHSe. Caregiver SHSe beliefs were more consistently associated with HSBs and SHSe than were general psychosocial factors.

CONCLUSIONS

Despite greater HSB likelihood and higher perceived importance of HSBs among nonsmoking versus smoking primary caregivers, SHSe reduction self-efficacy and intent are protective for Head Start students at high-risk for exposure. Pediatric healthcare providers and early education professionals may be able to support SHSe reduction efforts (e.g., smoking cessation, HSB implementation) and reduce children's SHSe with counseling strategies to address caregivers' HSB self-efficacy, intent, and related behaviors.

Full and home smoking ban adoption after a randomized controlled trial targeting secondhand smoke exposure reduction

INTRODUCTION

The current study examined home and full (i.e., home plus car) smoking ban adoption as secondary outcomes to a randomized controlled trial targeting reduced secondhand smoke exposure (SHSe) for children under treatment for cancer.

METHODS

Families with at least 1 adult smoker who reported SHSe for their children (n = 119) were randomized to control or intervention conditions and followed for 1 year with 5 assessments. Both groups were advised of the negative health outcomes associated with SHSe; the intervention group provided more in-depth counseling from baseline to 3 months. Parents reported on household and car smoking behavior, demographic, psychosocial, and medical/treatment-related information.

RESULTS

Regardless of group assignment, there was an increase in home (odds ration [OR] = 1.16, p = .074) and full (OR = 1.37, p = .001) smoking ban adoption across time. Families in the intervention group were more likely to adopt a full ban by 3 months, but this difference was nonsignificant by 12 months. Married parents (OR = 2.33, p = .006) and those with higher self-efficacy for controlling children's SHSe (OR = 1.11, p = .023) were more likely to have a home smoking ban; parents who reported smoking fewer cigarettes were more likely to adopt a home (OR = 1.62, p < .0001) or full (OR = 7.32, p = .038) ban.

CONCLUSIONS

Smoking bans are in-line with Healthy People 2020's tobacco objectives and may be more feasible for parents with medically compromised children for immediate SHSe reduction. Furthermore, interventions targeting full smoking bans may be a more effective for comprehensive elimination of SHSe.
