Koori Quit Pack: A feasibility study of a multi-component mailout smoking cessation support for Aboriginal and Torres Strait Islander people: "I would recommend it to anybody. It's just so much easier".

INTRODUCTION: Smoking is the leading cause of preventable death among Aboriginal and Torres Strait Islander people. The Koori1 Quit Pack study aimed to assess the feasibility of a multi-component mailout smoking cessation intervention to reduce smoking among Aboriginal and Torres Strait Islander people. METHODS: A non-randomised, single-group feasibility study conducted among Aboriginal and Torres Strait Islander people who reported current smoking. The intervention package included information pamphlets and resources on quitting, referral offer to Aboriginal Quitline and optional free Nicotine Replacement Therapies (NRT). Follow-up was conducted at 2-weeks, 6-weeks, 10-weeks and 6-months post recruitment. Feasibility outcomes were recruitment and retention rates, uptake of intervention components and smoking abstinence at 6-week follow-up (primary end point). Cessation outcomes were analysed using both a complete case analysis and intention-to-treat approach. RESULTS: 165 participants were recruited, 111 (67.3%), 79 (47.9%), 59 (35.8%), and 94 (57%) participants completed the 2-week, 6-week, 10-week, and 6-month follow-up. At 10-week follow-up, 40.7% of participants used pamphlets and booklets, 13.6% used Quitline and > 90% used NRT. At 6-week follow-up, 87.3% reported a quit attempt and 46.8% sustained quitting. 46.8% were continuously smoke-free at the 6-week timepoint. The complete case analysis and the intention-to-treat analysis at 6-month shows a 7-day self-reported point prevalence abstinence of 34% and 19.4% respectively. CONCLUSION: The Koori Quit Pack mailout smoking cessation program was feasible to support Aboriginal and Torres Strait Islander people. The intervention resulted in a high smoking cessation rate and should be upscaled, implemented and evaluated nationally. IMPLICATIONS: Aboriginal and Torres Strait Islander people are disproportionately impacted by tobacco related harms, however the majority want to quit or wish they never took up smoking. Mailout cessation support is feasible, overcomes access barriers to evidence-based support and increases quitting success. We recommend a national mailout smoking cessation program is implemented for, and by Aboriginal and Torres Strait Islander people to accelerate declines in smoking prevalence to eliminate tobacco related death and disease.

"It's changed my life. I'm not smoking anymore. I don't want to smoke anymore": exploring the acceptability of mailout smoking cessation support for and by Aboriginal and Torres Strait Islander people.

INTRODUCTION: Aboriginal and Torres Strait Islander people want to quit smoking. There is global evidence of combination Nicotine Replacement Therapy (c-NRT) alongside behavioural support as best practice approach to smoking cessation care. However, there is limited adherence and acceptability research regarding NRT and behavioural supports for Aboriginal and Torres Strait Islander people. Similarly, there is limited research on what is considered culturally appropriate and safe support for Aboriginal and Torres Strait Islander people to quit smoking. METHODS: This Aboriginal-led qualitative study explored the acceptability of the Koori Quit Pack. Aboriginal and Torres Strait Islander participants shared experiences of quitting with the mailout c-NRT program and behavioural cessation support through Yarning. Reflexive thematic analysis was used to develop themes. RESULTS: Aboriginal and Torres Strait Islander people are motivated to quit smoking and have accessed cessation supports from health professionals. However, the support(s) received are not always appropriate or culturally safe. The Koori Quit Pack was deemed acceptable and useful for smoking cessation. Having access to smoking cessation care and knowledge of c-NRT helped people quit smoking, and support others to quit too. CONCLUSION: A combination of NRT products alongside culturally responsive behavioural support(s), delivered through a mailout package was a beneficial strategy to help Aboriginal and Torres Strait Islander people quit smoking. National implementation of such a package could assist to accelerate reductions in tobacco use, helping meet national smoking reduction targets and improve health outcomes. IMPLICATIONS: Cessation supports offered to Aboriginal and Torres Strait Islander people are not always culturally-safe or effectively delivered. The Koori Quit Pack provided Aboriginal and Torres Strait Islander people with culturally-safe smoking cessation support delivered for and by Aboriginal and Torres Strait Islander people, demonstrating mailout smoking cessation supports as acceptable and highly valued. Mailout support eliminates accessibility barriers to cessation care while providing tools and knowledge to quit can lead to smoke-free behaviours among individuals and communities. Country-wide availability of this program can accelerate reductions in tobacco use, helping meet national targets and improve health outcomes consistent with the National Tobacco Strategy and the WHO Framework Convention on Tobacco Control.

National Health and Medical Research Council statement on electronic cigarettes: 2022 update.

INTRODUCTION: Electronic cigarette (e-cigarette) use in Australia has rapidly increased since the 2017 National Health and Medical Research Council (NHMRC) Chief Executive Officer (CEO) statement on e-cigarettes. The type of products available and the demographic characteristics of people using these products have changed. New evidence has been published and there is growing concern among public health professionals about the increased use, particularly among young people who do not currently smoke combustible cigarettes. The combination of these issues led NHMRC to review the current evidence and provide an updated statement on e-cigarettes. In this article, we describe the comprehensive process used to review the evidence and develop the 2022 NHMRC CEO statement on electronic cigarettes. MAIN RECOMMENDATIONS: E-cigarettes can be harmful; all e-cigarette users are exposed to chemicals and toxins that have the potential to cause adverse health effects. There are no health benefits of using e-cigarettes if you do not currently smoke tobacco cigarettes. Adolescents are more likely to try e-cigarettes if they are exposed to e-cigarettes on social media. Short term e-cigarette use may help some smokers to quit who have been previously unsuccessful with other smoking cessation aids. There are other proven safe and effective options available to help smokers to quit. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: The evidence base for the harms of e-cigarette use has strengthened since the previous NHMRC statement. Significant gaps in the evidence base remain, especially about the longer term health harms of using e-cigarettes and the toxicity of many chemicals in e-cigarettes inhaled as an aerosol.

Interventions from pregnancy to two years after birth for parents experiencing complex post-traumatic stress disorder and/or with childhood experience of maltreatment.

BACKGROUND: Acceptable, effective and feasible support strategies (interventions) for parents experiencing complex post-traumatic stress disorder (CPTSD) symptoms or with a history of childhood maltreatment may offer an opportunity to support parental recovery, reduce the risk of intergenerational transmission of trauma and improve life-course trajectories for children and future generations. However, evidence relating to the effect of interventions has not been synthesised to provide a comprehensive review of available support strategies. This evidence synthesis is critical to inform further research, practice and policy approaches in this emerging area. OBJECTIVES: To assess the effects of interventions provided to support parents who were experiencing CPTSD symptoms or who had experienced childhood maltreatment (or both), on parenting capacity and parental psychological or socio-emotional wellbeing. SEARCH METHODS: In October 2021 we searched CENTRAL, MEDLINE, Embase, six other databases and two trials registers, together with checking references and contacting experts to identify additional studies. SELECTION CRITERIA: All variants of randomised controlled trials (RCTs) comparing any intervention delivered in the perinatal period designed to support parents experiencing CPTSD symptoms or with a history of childhood maltreatment (or both), to any active or inactive control. Primary outcomes were parental psychological or socio-emotional wellbeing and parenting capacity between pregnancy and up to two years postpartum. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the eligibility of trials for inclusion, extracted data using a pre-designed data extraction form, and assessed risk of bias and certainty of evidence. We contacted study authors for additional information as required. We analysed continuous data using mean difference (MD) for outcomes using a single measure, and standardised mean difference (SMD) for outcomes using multiple measures, and risk ratios (RR) for dichotomous data. All data are presented with 95% confidence intervals (CIs). We undertook meta-analyses using random-effects models. MAIN RESULTS: We included evidence from 1925 participants in 15 RCTs that investigated the effect of 17 interventions. All included studies were published after 2005. Interventions included seven parenting interventions, eight psychological interventions and two service system approaches. The studies were funded by major research councils, government departments and philanthropic/charitable organisations. All evidence was of low or very low certainty. Parenting interventions Evidence was very uncertain from a study (33 participants) assessing the effects of a parenting intervention compared to attention control on trauma-related symptoms, and psychological wellbeing symptoms (postpartum depression), in mothers who had experienced childhood maltreatment and were experiencing current parenting risk factors. Evidence suggested that parenting interventions may improve parent-child relationships slightly compared to usual service provision (SMD 0.45, 95% CI -0.06 to 0.96; I2 = 60%; 2 studies, 153 participants; low-certainty evidence). There may be little or no difference between parenting interventions and usual perinatal service in parenting skills including nurturance, supportive presence and reciprocity (SMD 0.25, 95% CI -0.07 to 0.58; I2 = 0%; 4 studies, 149 participants; low-certainty evidence). No studies assessed the effects of parenting interventions on parents' substance use, relationship quality or self-harm. Psychological interventions Psychological interventions may result in little or no difference in trauma-related symptoms compared to usual care (SMD -0.05, 95% CI -0.40 to 0.31; I2 = 39%; 4 studies, 247 participants; low-certainty evidence). Psychological interventions may make little or no difference compared to usual care to depression symptom severity (8 studies, 507 participants, low-certainty evidence, SMD -0.34, 95% CI -0.66 to -0.03; I2 = 63%). An interpersonally focused cognitive behavioural analysis system of psychotherapy may slightly increase the number of pregnant women who quit smoking compared to usual smoking cessation therapy and prenatal care (189 participants, low-certainty evidence). A psychological intervention may slightly improve parents' relationship quality compared to usual care (1 study, 67 participants, low-certainty evidence). Benefits for parent-child relationships were very uncertain (26 participants, very low-certainty evidence), while there may be a slight improvement in parenting skills compared to usual care (66 participants, low-certainty evidence). No studies assessed the effects of psychological interventions on parents' self-harm. Service system approaches One service system approach assessed the effect of a financial empowerment education programme, with and without trauma-informed peer support, compared to usual care for parents with low incomes. The interventions increased depression slightly (52 participants, low-certainty evidence). No studies assessed the effects of service system interventions on parents' trauma-related symptoms, substance use, relationship quality, self-harm, parent-child relationships or parenting skills. AUTHORS' CONCLUSIONS: There is currently a lack of high-quality evidence regarding the effectiveness of interventions to improve parenting capacity or parental psychological or socio-emotional wellbeing in parents experiencing CPTSD symptoms or who have experienced childhood maltreatment (or both). This lack of methodological rigour and high risk of bias made it difficult to interpret the findings of this review. Overall, results suggest that parenting interventions may slightly improve parent-child relationships but have a small, unimportant effect on parenting skills. Psychological interventions may help some women stop smoking in pregnancy, and may have small benefits on parents' relationships and parenting skills. A financial empowerment programme may slightly worsen depression symptoms. While potential beneficial effects were small, the importance of a positive effect in a small number of parents must be considered when making treatment and care decisions. There is a need for further high-quality research into effective strategies for this population.

Don't Follow the Smoke-Listening to the Tobacco Experiences and Attitudes of Urban Aboriginal Adolescents in the Study of Environment on Aboriginal Resilience and Child Health (SEARCH).

Preventing smoking among young Aboriginal people is important for reducing health inequities. Multiple factors were associated with adolescent smoking in the SEARCH baseline survey (2009-12) and discussed in a follow-up qualitative study that aimed to inform prevention programs. Twelve yarning circles were facilitated by Aboriginal research staff at two NSW sites in 2019 with 32 existing SEARCH participants aged 12-28 (17 female, 15 male). Open discussion around tobacco was followed by a card sorting activity, prioritising risk and protective factors and program ideas. The age of initiation varied by generation. Older participants had established smoking in their early adolescence, whereas the current younger teens had little exposure. Some smoking commenced around high school (from Year 7), and social smoking increased at age 18. Mental and physical health, smoke-free spaces and strong connections to family, community and culture promoted non-smoking. The key themes were (1) drawing strength from culture and community; (2) how the smoking environment shapes attitudes and intentions; (3) non-smoking as a sign of good physical, social and emotional wellbeing; and (4) the importance of individual empowerment and engagement for being smoke-free. Programs promoting good mental health and strengthening cultural and community connections were identified as a priority for prevention.

Factors associated with breastfeeding initiation and maintenance for Aboriginal and Torres Strait Islander women in Australia: A systematic review and narrative analysis.

BACKGROUND: Australian Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) women breastfeed at lower rates than non-Aboriginal women. Little is known about factors associated with breastfeeding specific to Aboriginal women and infants. AIM: Determine the protective and risk factors associated with breastfeeding for Aboriginal women in Australia. METHODS: CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English reporting protective and risk factors associated with breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Ten percent of papers were co-screened, and two reviewers completed data extraction. Narrative data synthesis was used. FINDINGS: The initial search identified 12,091 records, with 31 full text studies retrieved, and 17 reports from 14 studies met inclusion criteria. Protective factors included living in a remote area, attending an Aboriginal-specific service, attending a regional service, higher levels of education attainment, increased maternal age, living in larger households, being partnered, and having a higher reported number of stressful events and social health issues. The identified risk factors were smoking in pregnancy, admission to SCN or NICU, and being multiparous. CONCLUSION: This review identified factors associated with breastfeeding for Aboriginal women. Government focus, support, and consistent funding are required to plan and implement evidence-based interventions and services for Aboriginal women and infants in urban, rural, remote, and very remote locations. Rigorous research is required to understand the Aboriginal-specific factors associated with breastfeeding to improve rates and health outcomes for Aboriginal women and infants.

Koori Quit Pack mailout smoking cessation support for Aboriginal and Torres Strait Islander people who smoke: a feasibility study protocol.

INTRODUCTION: Smoking remains the leading preventable cause of death for Aboriginal and Torres Strait Islander people in Australia. Aboriginal and Torres Strait Islander people who smoke are more likely to make a quit attempt than their non-Aboriginal counterparts but less likely to sustain the quit attempt. There is little available evidence specifically for and by Indigenous peoples to inform best practice smoking cessation care.The provision of a free Koori Quit Pack with optional nicotine replacement therapy sent by mail may be a feasible, acceptable and effective way to access stop smoking support for Aboriginal and Torres Strait Islander peoples. METHODS AND ANALYSIS: An Aboriginal-led, multisite non-randomised single-group, pre-post feasibility study across three states in Australia will be conducted. Participants will be recruited via service-targeted social media advertising and during usual care at their Aboriginal Community Controlled Health Services. Through a process of self-referral, Aboriginal and Torres Strait Islander people who smoke daily will complete a survey and receive mailout smoking cessation support. Data will be collected over the phone by an Aboriginal Research Assistant. This pilot study will inform the development of a larger, powered trial. ETHICS AND DISSEMINATION: Ethics approval has been obtained from the Aboriginal Health & Medical Research Council Ethics Committee of New South Wales (NSW) (#1894/21) and the University of Newcastle (#H-2022-0174). Findings will be reported through peer-reviewed journals and presentations at relevant local, national and international conferences. The findings will be shared with the NSW and Victoria Quitline, Aboriginal Health and Medical Research Council and Victorian Aboriginal Community Controlled Organisation and the National Heart Foundation. TRIAL REGISTRATION NUMBER: ACTRN12622000654752.

E-cigarette use and the relationship to smoking among Aboriginal and Torres Strait Islander and non-Indigenous Australian Secondary Students, 2017.

OBJECTIVE: Estimate the prevalence of e-cigarette use (vaping) among Aboriginal and Torres Strait Islander adolescents and explore the relationship between vaping and tobacco use. METHODS: N=18,199 students aged 12-17 years (n=1,097 Aboriginal and Torres Strait Islander) participating in the 2017 Australian Secondary Students' Alcohol and Drug (ASSAD) Survey self-reported their e-cigarette and lifetime, past month and past week smoking behaviours. RESULTS: Twenty-two per cent of Aboriginal and Torres Strait Islander students (14% all) reported having ever used e-cigarettes. Significantly greater odds of e-cigarette use among Aboriginal and Torres Strait Islander students was observed overall, but not among regular (past month/week) smokers. There were significant associations between e-cigarette use and any level of smoking for all students (p<0.001), with no variation by Indigenous status. While e-cigarette use was more common among smokers, 28% of Aboriginal and Torres Strait Islander ever-vapers (35% all ever-vapers) were never smokers. CONCLUSIONS: There is substantial prevalence of e-cigarette ever-use among Australian secondary students, including Aboriginal and Torres Strait Islander students, and a strong relationship with tobacco use. IMPLICATIONS FOR PUBLIC HEALTH: Policies facilitating e-cigarette access must not undercut tobacco control efforts for adolescents, particularly Aboriginal and Torres Strait Islander people who continue to experience higher smoking rates.

Smoking cessation support strategies for Aboriginal and Torres Strait Islander women of reproductive age: findings from the Which Way? study.

OBJECTIVE: To identify smoking cessation support strategies that resonate with Aboriginal and Torres Strait Islander women. DESIGN, SETTING AND PARTICIPANTS: A national cross-sectional survey of Aboriginal and Torres Strait Islander women aged 16-49 years who were smokers or ex-smokers was conducted online during the period July to October 2020. MAIN OUTCOME MEASURES: Preferred strategies, providers and locations for smoking cessation support. RESULTS: Among a total of 428 women who participated in the survey, group-based support and holistic support were the most preferred strategies (preferred by 31.8% and 22.2% of women, respectively). Use of an Aboriginal health service was positively associated with choosing holistic support programs (prevalence ratio, 1.14 [95% CI, ≥ 1.00-1.28]). Women with high or moderate nicotine dependency were more likely to consider group-based support to be helpful (prevalence ratio, 1.13 [95% CI, ≥ 1.00-1.27]) than those with low nicotine dependency. The most preferred providers for smoking cessation support were Aboriginal health workers (64.3%). Most women (73.4%) preferred face-to-face support at an Aboriginal health service, 38.8% preferred online support and 34.8% preferred phone support. A higher percentage of older women (≥ 35 years) preferred online or phone support (prevalence ratio, 1.70 [95% CI, 1.03-2.80]) compared with younger women (16-20 years). Use of an Aboriginal health service was positively associated with preference for an Aboriginal health worker (prevalence ratio, 1.35 [95% CI, 1.12-1.62]), and receiving face-to-face support at an Aboriginal health service (prevalence ratio, 1.28 [95% CI, 1.10-1.49]). CONCLUSION: Aboriginal and Torres Strait Islander women prefer a range of cessation supports, with most women preferring group support and holistic approaches. Cessation supports that resonated with women varied by age, remoteness, nicotine dependence, and whether participants used an Aboriginal health service. Women want support to quit smoking from the Aboriginal health workers at their Aboriginal health service, at their health care providers and in their community. Comprehensive, multifaceted supports are required. Online support and phone-based support are also preferred by some women, which helps to increase accessibility. Appropriate models of care - including sufficient funding for Aboriginal health services and Aboriginal health workers - are required and should be developed in partnership with communities to implement meaningful and culturally safe cessation care. This research demonstrates the need for and importance of multifaceted, comprehensive cessation support strategies.

Smoking and quitting characteristics of Aboriginal and Torres Strait Islander women of reproductive age: findings from the Which Way? study.

OBJECTIVE: To describe smoking characteristics, quitting behaviour and other factors associated with longest quit attempt and the use of nicotine replacement therapy (NRT) and stop-smoking medication (SSM) in a population of Indigenous Australian women of reproductive age. DESIGN, SETTING AND PARTICIPANTS: A national cross-sectional survey of Aboriginal and Torres Strait Islander women aged 16-49 years who were smokers or ex-smokers was conducted online during the period July to October 2020. MAIN OUTCOME MEASURES: Quitting experience: attempt to cut down, time since last quit attempt, longest period without smoking, attempt to cut down during last quit attempt, any use of NRT and/or SSM. RESULTS: Most of the 428 participating women (302 [70.6%]) reported using an Aboriginal health service. Younger women (16-20-year-olds) smoked fewer cigarettes daily (24/42 [57.1%], 0-5 cigarettes per day), waited longer to smoke after waking (20/42 [47.6%], > 60 minutes after waking), and were categorised as low smoking dependency compared with those aged 35 years and over. One-third of women (153 [35.7%]) had ever used NRT and/or SSM. A greater proportion of older women (35-49-year-olds) had sustained a quit attempt for years (62/149 [45.6%]) and reported trying NRT and/or SSM (78/149 [52.4%]) than women in younger age groups. Quitting suddenly rather than gradually was significantly associated with sustained abstinence (prevalence ratio, 1.27 [95% CI, 1.10-1.48]). Among women who had never used NRT or SSM, most (219/275 [79.6%]) reported reasons for this in the category of attitudes and beliefs. NRT and SSM use was also more likely among women who were confident talking to their doctor about quitting (odds ratio, 2.50 [95% CI, 1.23-5.10]) and those who received most of their information from a health professional (odds ratio, 1.71 [95% CI, 1.11-2.63]). CONCLUSION: Aboriginal and Torres Strait Islander women want to quit smoking and are making attempts to quit. Quitting suddenly, rather than reducing cigarette consumption, is associated with increased sustained abstinence. Health providers can enable access and uptake of NRT and/or SSM and should recognise that NRT and/or SSM use may change over time. Consistent messaging, frequent offers of smoking cessation support, and access to a range of smoking cessation supports should be provided to Aboriginal and Torres Strait Islander women to enable them to be smoke-free.

Interrogating the intentions for Aboriginal and Torres Strait Islander health: a narrative review of research outputs since the introduction of Closing the Gap.

Despite the "best of intentions", Australia has fallen short of federal targets to close the gap in disproportionate health outcomes between Aboriginal and non-Aboriginal Australians. We examined 2150 original research articles published over the 12-year period (from 2008 to 2020), of which 58% used descriptive designs and only 2.6% were randomised controlled trials. There were few national studies. Studies were most commonly conducted in remote settings (28.8%) and focused on specific burdens of disease prevalent in remote areas, such as infectious disease, hearing and vision. Analytic observational designs were used more frequently when addressing burdens of disease, such as cancer and kidney and urinary, respiratory and endocrine diseases. The largest number of publications focused on mental and substance use disorders (n = 322, 20.5%); infectious diseases (n = 222, 14.1%); health services planning, delivery and improvement (n = 193, 33.5%); and health and wellbeing (n = 170, 29.5%). This review is timely given new investments in Aboriginal health, which highlights the importance of Aboriginal researchers, community leadership and research priority. We anticipate future outputs for Aboriginal health research to change significantly from this review, and join calls for a broadening of our intellectual investment in Aboriginal health.

Building an Indigenous-Led Evidence Base for Smoking Cessation Care among Aboriginal and Torres Strait Islander Women during Pregnancy and Beyond: Research Protocol for the Which Way? Project.

Strong and healthy futures for Aboriginal and Torres Strait Islander people requires engagement in meaningful decision making which is supported by evidence-based approaches. While a significant number of research publications state the research is co-designed, few describe the research process in relation to Indigenous ethical values. Improving the health and wellbeing of Aboriginal and Torres Strait Islander mothers and babies is crucial to the continuation of the oldest living culture in the world. Developing meaningful supports to empower Aboriginal and Torres Strait Islander mothers to quit smoking during pregnancy is paramount to addressing a range of health and wellbeing outcomes. Aboriginal and Torres Strait Islander women have called for non-pharmacological approaches to smoking cessation during pregnancy. We describe a culturally responsive research protocol that has been co-designed and is co-owned with urban and regional Aboriginal communities in New South Wales. The project has been developed in line with the AH&MRC's (Aboriginal Health & Medical Research Council) updated guidelines for ethical research with Aboriginal and Torres Strait Islander communities. Ethics approvals have been granted by AH&MRC #14541662 University of Newcastle HREC H-2020-0092 and the Local Health District ethics committee 2020/ETH02095. Results will be disseminated through peer reviewed articles, community reports, infographics, and online social media content.

Smoking behaviours and other substance use among Indigenous and non-Indigenous Australian secondary students, 2017.

INTRODUCTION AND AIMS: Smoking is a major cause of preventable illness for Indigenous peoples. As most regular smoking is established during adolescence when other substances are often first used, effective tobacco prevention requires an understanding of the patterns of related substance use for Indigenous youth. DESIGN AND METHODS: We reviewed smoking among Indigenous students through cross-sectional analyses of the 2017 Australian Secondary Students' Alcohol and Drug survey and compared findings to non-Indigenous participants. We used logistic regression to evaluate differences in prevalence of tobacco, alcohol and cannabis use, and how smoking and other substance use were related. RESULTS: Past month smoking was strongly associated with alcohol and cannabis use for both Indigenous and non-Indigenous students. The association between tobacco and cannabis use did not differ by Indigenous status, but the tobacco and alcohol use association was weaker for Indigenous students (P = 0.004). However, the prevalence of tobacco [odds ratio (OR) 1.91 (95% confidence interval; CI 1.55, 2.36)], alcohol [OR 1.44 (1.25, 1.66)] and cannabis [OR 1.97 (1.56, 2.48)] use in the past month was significantly higher in Indigenous than non-Indigenous students. Even within the most socially advantaged sub-group, Indigenous students were more likely to smoke than non-Indigenous students [OR 3.37 (2.23, 5.09)]. DISCUSSION AND CONCLUSIONS: Cannabis and alcohol use are important predictors of smoking for all students. Tobacco policies and community programs must address common determinants of tobacco and other substance use, including resilience and social influence skills as well as broader family and community factors that may be different for Indigenous students.

Fetal safety of nicotine replacement therapy in pregnancy: systematic review and meta-analysis.

BACKGROUND AND AIMS: Smoking in pregnancy causes substantial avoidable harm to mothers and offspring; nicotine replacement therapy (NRT) may prevent this, and is used to help women to quit. A recently updated Cochrane Review of randomized controlled trials (RCTs) investigating impacts of NRT in pregnancy focuses primarily on efficacy data, but also reports adverse impacts from NRT. Here we identify and summarize NRT impacts on adverse pregnancy outcomes reported in non-randomized controlled trials (non-RCTs). METHODS: Systematic reviews and meta-analyses of RCTs and non-RCT studies of NRT in pregnancy, with design-specific risk of bias assessment and grading of recommendations, assessment, development and evaluations (GRADE) criteria applied to selected outcomes. FINDINGS: Relevant Cochrane Review findings are reported alongside those from this new review. Seven RCTs were included; n = 2340. Nine meta-analyses were performed; non-statistically significant estimates indicated potentially reduced risk from NRT compared with smoking for mean birth weight, low birth weight, preterm birth, intensive care admissions, neonatal death, congenital anomalies and caesarean section and potentially increased risks for miscarriage and stillbirth. GRADE assessment for mean birth weight and miscarriage outcomes indicated 'low' confidence in findings. Twenty-three non-RCTs were included; n = 931 163. Eleven large studies from five routine health-care cohorts reported clinical outcomes; 12 small studies investigated mainly physiological outcomes within in-patient women given NRT. Findings from meta-analyses for congenital anomalies, stillbirth and preterm birth were underpowered and not in a consistent direction; GRADE assessment of confidence in findings was 'very low'. Routine health-care studies were of higher quality, but implications of reported findings were unclear as there was inadequate measurement and reporting of women's smoking. CONCLUSIONS: Available evidence from randomized controlled trials and non-randomized comparative studies does not currently provide clear evidence as to whether maternal use of nicotine replacement therapy during pregnancy is harmful to the fetus.

Staying smoke-free: Factors associated with nonsmoking among urban Aboriginal adolescents in the Study of Environment on Aboriginal Resilience and Child Health (SEARCH).

ISSUE ADDRESSED: To examine the factors associated with preventing regular smoking among Aboriginal adolescents. METHODS: Cross-sectional analysis of data from 106 Aboriginal adolescents aged 12-17 years, and their caregivers, from four Aboriginal Community Controlled Health Services in urban New South Wales, 2008-2012. The relation of individual, social, environmental and cultural factors to having 'never' smoked tobacco regularly was examined using Poisson regression. RESULTS: Overall, 83% of adolescents had never smoked regularly; 13 reported current and five past smoking. Most lived in smoke-free homes (60%) despite 75% reporting at least one current smoker caregiver. Participants were significantly more likely to have never smoked regularly if they had good mental health (PR = 1.4, 95% CI: 1.1-1.9), their mother as their primary caregiver (1.3, 1.0-1.6), good family relationships (1.2, 1.0-1.5), stable housing (1.3, 1.1-1.7), had never used alcohol (1.8, 1.3-2.4), were not sexually active (3.1, 1.3- 7.2) and had no criminal justice interactions (1.8, 1.2-2.8). CONCLUSIONS: Most participants lived in smoke-free homes and the vast majority had never smoked regularly. Promoting good mental health and strengthening social connections may be protective against smoking as those experiencing less social disruption were more likely to have never smoked regularly. Smoking may be an indicator of psychosocial conditions and a prompt for screening and simultaneous treatment. SO WHAT?: Organisations should be resourced to deliver holistic adolescent health promotion programs. Programs and policies should support positive family relationships and stable housing as this may protect against the uptake of regular smoking.

The decline of smoking initiation among Aboriginal and Torres Strait Islander secondary students: implications for future policy.

OBJECTIVE: Smoking is a major cause of preventable illness for Aboriginal and Torres Strait Islander people, with most commencing in adolescence. Understanding trends in youth tobacco use can inform prevention policies and programs. METHODS: Logistic regression models examined smoking trends among Aboriginal and Torres Strait Islander and all students aged 12-17 years, in five nationally representative triennial surveys, 2005-2017. Outcomes measured lifetime, past month, past week tobacco use and number of cigarettes smoked daily (smoking intensity). RESULTS: Aboriginal and Torres Strait Islander students' never smoking increased (2005: 49%, 2017: 70%) with corresponding declines in past month and week smoking. Smoking intensity reduced among current smokers (low intensity increased 2005: 67%, 2017: 77%). Trends over time were similar for Aboriginal and Torres Strait Islander students as for all students (8-10% annual increase in never smoking). CONCLUSIONS: Most Aboriginal and Torres Strait Islander students are now never smokers. Comparable declines indicate similar policy impact for Aboriginal and Torres Strait Islander and all students. Implications for Public Health: Comprehensive population-based tobacco control policies can impact all students. Continued investment, including in communities, is needed to maintain and accelerate reductions among Aboriginal and Torres Strait Islander students to achieve equivalent prevalence rates and reduce health inequities.

Changes in the age young Aboriginal and Torres Strait Islander people start smoking, 2002-2015.

OBJECTIVES: To analyse trends in smoking initiation and prevalence among young Aboriginal and Torres Strait Islander people (Indigenous people) to identify which stages of adolescence and young adulthood prevention activities should target. METHODS: Secondary analysis of 'daily smoking' and 'never smoked' responses from Indigenous people aged 15 years and older in five national Indigenous surveys from 2002 to 2014-15, and of initiation age among those aged 18 years and older in 2004-05 and 2012-13. RESULTS: Smoking prevalence among 15-24-year-olds declined significantly between 2002 and 2014-15, falling 14 percentage points (95%percnt; confidence interval [CI] 8, 21) from 45%percnt; to 31%percnt;. The greatest decline was among 18-19-year-olds, with a decrease of 17 percentage points (95% CI 4, 29) from 48%percnt; to 31%percnt;. The proportion of 15-24-year-olds who had never smoked increased significantly, by 12 percentage points (95%percnt; CI 6, 18) from 44%percnt; in 2002 to 56%percnt; in 2014-15. Between 2004-05 and 2012-13, the proportion of 18-24-year-old smokers who had started daily smoking before the age of 18 years declined significantly, down 8 percentage points (95%percnt; CI 2, 15) from 84%percnt; to 76%percnt;. In 2012-13, 24%percnt; of smokers aged 18-24 years started daily smoking after age 18, half (49%percnt;) started between 15 and 18 years, and around a quarter started before age 15. CONCLUSIONS: There have been significant declines in smoking prevalence among young Indigenous people between 2002 and 2014-15 as fewer take up smoking. Smoking initiation occurs over a wide age range. The majority of daily smokers started before the age of 18; however, initiation may be delayed until early adulthood for an increasing number. The challenge for tobacco prevention is to reach young people in early adolescence and continue to reinforce smoke-free intentions into young adulthood.

Pharmacological interventions for promoting smoking cessation during pregnancy.

BACKGROUND: Tobacco smoking in pregnancy causes serious health problems for the developing fetus and mother. When used by non-pregnant smokers, pharmacotherapies (nicotine replacement therapy (NRT), bupropion, and varenicline) are effective for increasing smoking cessation, however their efficacy and safety in pregnancy remains unknown. Electronic cigarettes (ECs) are becoming widely used, but their efficacy and safety when used for smoking cessation in pregnancy are also unknown. OBJECTIVES: To determine the efficacy and safety of smoking cessation pharmacotherapies and ECs used during pregnancy for smoking cessation in later pregnancy and after childbirth, and to determine adherence to smoking cessation pharmacotherapies and ECs for smoking cessation during pregnancy. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (20 May 2019), trial registers, and grey literature, and checked references of retrieved studies. SELECTION CRITERIA: Randomised controlled trials (RCTs) conducted in pregnant women, comparing smoking cessation pharmacotherapy or EC use with either placebo or no pharmacotherapy/EC control. We excluded quasi-randomised, cross-over, and within-participant designs, and RCTs with additional intervention components not matched between trial arms. DATA COLLECTION AND ANALYSIS: We followed standard Cochrane methods. The primary efficacy outcome was smoking cessation in later pregnancy; safety was assessed by 11 outcomes (principally birth outcomes) that indicated neonatal and infant well-being. We also collated data on adherence to trial treatments. We calculated the risk ratio (RR) or mean difference (MD) and the 95% confidence intervals (CI) for each outcome for each study, where possible. We grouped eligible studies according to the type of comparison. We carried out meta-analyses where appropriate. MAIN RESULTS: We included 11 trials that enrolled a total of 2412 pregnant women who smoked at enrolment, nine trials of NRT and two trials of bupropion as adjuncts to behavioural support, with comparable behavioural support provided in the control arms. No trials investigated varenicline or ECs. We assessed four trials as at low risk of bias overall. The overall certainty of the evidence was low across outcomes and comparisons as assessed using GRADE, with reductions in confidence due to risk of bias, imprecision, and inconsistency. Compared to placebo and non-placebo (behavioural support only) controls, there was low-certainty evidence that NRT increased the likelihood of smoking abstinence in later pregnancy (RR 1.37, 95% CI 1.08 to 1.74; I² = 34%, 9 studies, 2336 women). However, in subgroup analysis by comparator type, there was a subgroup difference between placebo-controlled and non-placebo controlled RCTs (test for subgroup differences P = 0.008). There was unclear evidence of an effect in placebo-controlled RCTs (RR 1.21, 95% CI 0.95 to 1.55; I² = 0%, 6 studies, 2063 women), whereas non-placebo-controlled trials showed clearer evidence of a benefit (RR 8.55, 95% CI 2.05 to 35.71; I² = 0%, 3 studies, 273 women). An additional subgroup analysis in which studies were grouped by the type of NRT used found no difference in the effectiveness of NRT in those using patches or fast-acting NRT (test for subgroup differences P = 0.08). There was no evidence of a difference between NRT and control groups in rates of miscarriage, stillbirth, premature birth, birthweight, low birthweight, admissions to neonatal intensive care, caesarean section, congenital abnormalities, or neonatal death. In one study infants born to women who had been randomised to NRT had higher rates of 'survival without developmental impairment' at two years of age compared to the placebo group. Non-serious adverse effects observed with NRT included headache, nausea, and local reactions (e.g. skin irritation from patches or foul taste from gum), but data could not be pooled. Adherence to NRT treatment regimens was generally low. We identified low-certainty evidence that there was no difference in smoking abstinence rates observed in later pregnancy in women using bupropion when compared to placebo control (RR 0.74, 95% CI 0.21 to 2.64; I² = 0%, 2 studies, 76 women). Evidence investigating the safety outcomes of bupropion use was sparse, but the existing evidence showed no difference between the bupropion and control group. AUTHORS' CONCLUSIONS: NRT used for smoking cessation in pregnancy may increase smoking cessation rates in late pregnancy. However, this evidence is of low certainty, as the effect was not evident when potentially biased, non-placebo-controlled RCTs were excluded from the analysis. Future studies may therefore change this conclusion. We found no evidence that NRT has either positive or negative impacts on birth outcomes; however, the evidence for some of these outcomes was also judged to be of low certainty due to imprecision and inconsistency. We found no evidence that bupropion may be an effective aid for smoking cessation during pregnancy, and there was little evidence evaluating its safety in this population. Further research evidence on the efficacy and safety of pharmacotherapy and EC use for smoking cessation in pregnancy is needed, ideally from placebo-controlled RCTs that achieve higher adherence rates and that monitor infants' outcomes into childhood. Future RCTs of NRT should investigate higher doses than those tested in the studies included in this review.

Factors Influencing Smoking Among Indigenous Adolescents Aged 10-24 Years Living in Australia, New Zealand, Canada, and the United States: A Systematic Review.

INTRODUCTION: Smoking rates are higher among Indigenous populations in most high-income countries with initiation primarily occurring in adolescence for all population groups. This review aims to identify protective and risk factors for smoking behavior among Indigenous adolescents and young adults. AIMS AND METHODS: We searched Medline, Embase, and Psychinfo for all original research published between January 2006 and December 2016 that reported influences on smoking for Indigenous adolescents or young adults aged 10-24 living in Australia, New Zealand, Canada, and the United States (US). Extracted data were coded to individual, social, and environmental level categories using a modified Theory of Triadic Influence framework. RESULTS: A total of 55 studies were included, 41 were descriptive quantitative and 14 qualitative, and 26 included Indigenous participants only. The majority were from the US (32). Frequently reported influences were at the individual and social levels such as increasing age; attitudes and knowledge; substance use; peer and family relationships; smoking norms; mental health; physical activity. At the environmental level, smoke-free spaces; second-hand smoke exposure; high community level prevalence; and social marketing campaigns were also frequently reported. Some studies referenced price, access, and traditional tobacco use. Few reported historical and cultural factors. CONCLUSIONS: Young Indigenous people experience similar influences to other populations such as smoking among family and friends. Greater youth smoking is related to broader community level prevalence, but few studies explore the distal or historical contributing factors such as traditional tobacco use, colonization, experiences of intergenerational trauma and discrimination, or the role of cultural connection. IMPLICATIONS: This review identified a range of factors that influence Indigenous youth smoking and contributes to an understanding of what prevention measures may be effective. Youth tobacco use occurs alongside other substance use and may also serve as an indicator of mental health. Comprehensive community-based programs that work more broadly to address the risk factors related to tobacco, including improving youth mental health, will be important for other behaviors as well. This research highlights the importance of social influence and need for ongoing denormalization of smoking. Future Indigenous led and community owned research is needed to identify likely protective cultural factors.

Ngu-ng-gi-la-nha (to exchange) knowledge. How is Aboriginal and Torres Strait Islander people's empowerment being upheld and reported in smoking cessation interventions during pregnancy: a systematic review.

Smoking during pregnancy is a national priority to improve Aboriginal health. Empowerment approaches underpin the priorities set by the government to improve Aboriginal health and wellbeing; however, empowerment is seldom evaluated within interventions for Aboriginal people. Literature was searched to April 2018 and data was extracted using an assessment tool with domains of individual and community empowerment in smoking cessation during pregnancy studies with Aboriginal women. Three interventions were found in published and grey literature. Elements of individual empowerment were embedded in all interventions. Interventions considered barriers for Aboriginal women to quit smoking and areas for capacity building. Interventions used health education resources. There was limited reporting of community empowerment domains. Aboriginal ethics and capacity building was the only criterium addressed by all studies. Interventions are incorporating individual empowerment, but seldom report community empowerment. The development of reporting guidelines or extensions of current guidelines would be beneficial to set a consistently high standard reporting across Aboriginal health interventions, similar to the work conducted to develop the extension of Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Equity (PRISMA-E) for health equity in systematic review reporting. Reporting empowerment domains would reflect the government priority of empowerment to improve Aboriginal health, as well as enhancing knowledge translation into practice.
