The aim of this review of reviews was to collate the latest evidence from systematic reviews about the maternal and child health outcomes of being exposed to tobacco and nicotine during pregnancy; the effectiveness of interventions designed to reduce these exposures, and barriers to and facilitators of smoking cessation during pregnancy. Two databases were searched to obtain systematic reviews published from 2010 to 2019. Pertinent data from 76 articles were summarized using a narrative synthesis (PROSPERO reference: CRD42018085896). Exposure to smoke or tobacco in other forms during pregnancy is associated with an increased risk of obstetric complications and adverse health outcomes for children exposed in-utero. Counselling interventions are modestly effective, while incentive-based interventions appear to substantially increase smoking cessation. Nicotine replacement therapy is effective during pregnancy but the evidence is not conclusive. Predictors and barriers to smoking cessation in pregnancy are also discussed. Smoking during pregnancy poses substantial risk to mother’s and child’s health. Psychosocial interventions and nicotine replacement therapy (NRT) appear to be effective in helping pregnant women quit smoking. Barriers to smoking cessation must be identified and steps taken to eradicate them in order to reduce smoking among pregnant women. More research is needed on smoking cessation medications and e-cigarettes.

Background: Smoking cessation in pregnancy has unique challenges. Health providers (HP) may need support to successfully implement smoking cessation care (SCC) for pregnant women (PW). We aimed to synthesize qualitative data about views of HPs and PW on SCC during pregnancy using COM-B (Capability, Opportunity, Motivation, Behaviour) framework. Methods: A systematic search of online databases (MEDLINE, EMBASE, PsycINFO and CINAHL) using PRISMA guidelines. PW’s and HPs’ quotes, as well as the authors’ analysis, were extracted and double-coded (30%) using the COM-B framework. Results: Thirty-two studies included research from 5 continents: 13 on HPs’ perspectives, 15 on PW’s perspectives, four papers included both. HPs’ capability and motivation were affected by role confusion and a lack of training, time, and resources to provide interventions. HPs acknowledged that advice should be delivered while taking women’s psychological state (capability) and stressors into consideration. Pregnant women’s physical capabilities to quit (e.g., increased metabolism of nicotine and dependence) was seldom addressed due to uncertainty about nicotine replacement therapy (NRT) use in pregnancy. Improving women’s motivation to quit depended on explaining the risks of smoking versus the safety of quit methods. Women considered advice from HPs during antenatal visits as effective, if accompanied by resources, peer support, feedback, and encouragement. Conclusions: HPs found it challenging to provide effective SCC due to lack of training, time, and role confusion. The inability to address psychological stress in women and inadequate use of pharmacotherapy were additional barriers. These findings could aid in designing training programs that address HPs’ and PW’s attitudes and supportive campaigns for pregnant smokers.

Bushfires substantially increase the environmental health risks for people living in affected areas, especially the disadvantaged (e.g., those experiencing health inequities due to their socio-economic status, racial/ethnic backgrounds, geographic location and/or sexual orientation) and those with pre-existing health conditions. Pregnant women exposed to bushfire smoke are at a greater risk of adverse pregnancy and foetal outcomes, especially if they smoke tobacco, which may compound the toxic impacts. Bushfires may also exacerbate mental stress, leading to an increase in smoking. There are gaps in the evidence and more research is required on the combined effect of bushfire smoke and tobacco smoke on pregnant populations.

Objectives: The aim of this study was to identify current physical health guidelines for severe mental illness (SMI) and appraise them using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Instrument. Methods: Relevant research databases and grey literature were systematically searched to identify physical health guidelines for people with SMI. The grey literature was explored by web searches and targeted searches of the English websites of relevant peak bodies and government health agencies from Organisation for Economic Co-operation and Development countries. Included guidelines were independently appraised by two authors (NF and JH) using the AGREE II Instrument. Results: Of the 5352 records screened, 33 were assessed for eligibility. Fifteen practice guidelines met the inclusion criteria. The median domain scores as rated by the AGREE II Instrument ranged from 17% to 69%. The World Health Organization guideline, which demonstrated a broad range of clinical recommendations and sound methodological rigour, was rated the best. Conclusions: Most guidelines scored poorly when rated by the AGREE II Instrument. However, these guidelines may still be useful in assisting evidence-based clinical practice. The methodological rigour of future guidelines can be improved by ensuring the AGREE II domains are addressed during the development phase. What is known about the topic?: Compared with the general population, people with SMI experience greater chronic disease morbidity and mortality. There is limited evidence from randomised controlled trials to guide physical health care monitoring for people with SMI. Current guidelines and practice are largely based on expert consensus, clinical experience and good intentions. What does this paper add?: Using the AGREE II Instrument, this paper appraises the current physical health guidelines for people with SMI. The attributes of the guidelines examined included the evidence base, clarity of presentation, applicability in the real world, the involvement of stakeholders and conflicts of interest of various parties involved in guideline development. What are the implications for practitioners?: This review highlights the scarcity of high-quality and evidence-based guidelines for clinicians and researchers to address the physical health of people with SMI.
