Screening and early intervention for substance use during pregnancy: A retrospective case note review of antenatal care records.

INTRODUCTION: Screening for substance use during pregnancy is critical for enhancing maternal health and perinatal outcomes. However, disparities persist in screening and intervention rates within maternity services. This retrospective case note review explored contemporaneous practices around screening and interventions for substance use among pregnant women during routine antenatal care. METHODS: A random sample of 100 sets of maternity records were reviewed. Eligible cases included any woman attending initial pregnancy assessments at one of two South Australian metropolitan Hospital-based antenatal clinics, from July 2019-September 2020. Screening rates for past and current alcohol, tobacco and other substance use were identified and compared with data from a subset of a nationally representative survey. Intervention details and referral pathways were also assessed. RESULTS: The final sample of eligible cases (n = 93) demonstrated prioritisation of screening for current use, over past use, across all substances (p < 0.001). Screening was most likely for tobacco and least likely for e-cigarettes (p < 0.001). Significant underreporting of past use compared with the benchmark was identified for all substances (except tobacco, p = 0.224). Interventions typically involved written resources, which were usually declined by clients. DISCUSSION AND CONCLUSIONS: Despite longstanding recommendations, screening and intervention practices for substance use appear inconsistent. With the recent emergence of vaping, no evidence of updated approaches to identifying e-cigarette consumption in pregnant women was found. Several opportunities for enhancing routine screening and intervention practices within antenatal clinics were identified, and will inform the development of policy directives, targeted training modules, and other resources for health professionals working in these services.

Improving the quality of antenatal screening and early intervention for alcohol and other drug use: protocol for a multi-stage approach to systems reform.

BACKGROUND: Alcohol, tobacco and illicit drug use during pregnancy can cause significant harm to women and their developing fetuses. Despite recommendations for abstinence during pregnancy, some women continue to use, making screening for substance use during antenatal clinic attendances an important strategy for reducing risk. This study aims to improve the rates of screening and intervention for substance use among pregnant women, including appropriate referral for those who may be substance-dependent. The protocol outlined here focuses on a multi-stage implementation study. METHODS: This study will occur in four phases. Phase 1 will identify a baseline rate of screening and subsequent care at the antenatal clinics of two, South Australian hospital-based maternity services, through a retrospective case note audit. Rates of self-reported substance use identified in the case notes will also be compared against representative data from Adelaide Primary Health Network to establish rates of over or underreporting. Phase 2 will involve an online Training Needs Analysis of midwifery staff working at those services, to assess their knowledge, attitudes, beliefs, and commitment to the care of women who use substances during pregnancy. Phase 3 will involve a training package for all midwifery staff at those services, focused on routine screening for substance use, and how to provide appropriate care. Outcome measures from phase 2 will be reassessed during phase 3 and any changes since training will be evaluated. Phase 4 will then repeat phase 1 to compare the changes in rates of both screening and any associated intervention before and after training. DISCUSSION: From a public health perspective, this project has the potential to make a significant impact on reducing risk of harm from substance use disorders among pregnant women, and contribute to better health outcomes for their children. TRIAL REGISTRATION: This trial has been pre-registered under the Open Science Framework. REGISTRATION: https://doi.org/10.17605/OSF.IO/73FDZ .

Building workforce capacity to address substance use in primary health care: preliminary results from a mixed-methods pilot program.

BACKGROUND: Primary health care is critical to the prevention of alcohol, tobacco and other drug-related harms. Scaling-up screening, brief intervention and referral to treatment (SBIRT) within primary health care can reduce the burden of substance-related diseases, and improve downstream healthcare services. Building knowledge, skills and confidence among general practitioners (GPs), particularly in rural, regional and remote areas, to deliver SBIRT is an essential step. Therefore, this study aimed to pilot test a skills-based training program for GPs designed to build capacity for SBIRT delivery. METHODS: This pilot study investigated the acceptability of a structured, educational skills-based training program among GPs, as well as its preliminary effectiveness in inducing changes in confidence to deliver SBIRT, and in increasing knowledge about low-risk alcohol guidance. The training package was designed by experts in addiction medicine and public health, and involved a series of online webinars and in-person workshops at four locations across the South Eastern NSW Primary Healthcare Network catchment. RESULTS: A total of 18 GPs registered for the training, with six completing the final webinar. The GPs who completed all sessions demonstrated increases in confidence to deliver SBIRT and alcohol guidance knowledge from baseline. Qualitative feedback found the program acceptable, and GPs were able to successfully implement learnings into practice, and promote to colleagues. CONCLUSIONS: The results indicated the potential of this program at a national level, but highlighted the need for a range of additional incentives to encourage uptake and ongoing implementation.

Pre-Vaccination Human Papillomavirus Genotypes and HPV16 Variants among Women Aged 25 Years or Less with Cervical Cancer.

BACKGROUND: In 2007, Australia introduced a national human papillomavirus (HPV) vaccination program. In 2017, the onset of cervical screening changed from 18 to 25 years of age, utilising human papillomavirus (HPV) nucleic acid testing. The objective of the study is to describe the HPV genotypes and HPV16 variants in biopsies from women ≤ 25 years of age with cervical carcinoma (CC) (cases), compared with those aged >25 years (controls), in a pre-vaccination cohort. METHODS: HPV genotyping of archival paraffin blocks (n = 96) was performed using the INNO-LiPA HPV Genotyping assay. HPV16-positive samples were analysed for variants by type-specific PCR spanning L1, E2 and E6 regions. RESULTS: HPV16 was the commonest genotype in cases (54.5%, 12/22) and controls (66.7%, 46/69) (p = 0.30), followed by HPV18 (36.3%, 8/22 vs. 17.3% 12/69, respectively) (p = 0.08). Furthermore, 90% (20/22) of cases and 84.1% (58/69) of controls were positive for HPV16 or 18 (p = 0.42); 100% (22/22) of cases and 95.7% (66/69) of controls had at least one genotype targeted by the nonavalent vaccine (p = 0.3). The majority of HPV16 variants (87.3%, 48/55) were of European lineage. The proportion of unique nucleotide substitutions was significantly higher in cases (83.3%, 10/12) compared with controls (34.1%, 15/44), (p < 0.003, χ2, OR 9.7, 95%CI 1.7-97.7). CONCLUSIONS: Virological factors may account for the differences in CCs observed in younger compared with older women. All CCs in young women in this study had preventable 9vHPV types, which is important messaging for health provider adherence to new cervical screening guidelines.

Substance use in the emergency department: Screening for risky drug use, using the ASSIST-Lite.

INTRODUCTION: Substance use is a common contributing factor to emergency department (ED) presentations. While screening, brief intervention, and referral to treatment for alcohol and tobacco is common in ED settings, it is not routinely conducted for illicit substances. This study aimed to deploy the ASSIST-Lite to screen for risky use of alcohol and other drugs in the ED, to identify differences in risk based on between demographic characteristics. METHOD: All ED attenders, aged 18 years or older, deemed well enough to participate were approached. Recruitment occurred at the Royal Adelaide Hospital ED between May and June 2017. Participants were asked to self-complete the ASSIST-Lite in the ED waiting room. Overall, 632 people were approached, of which 479 (75.8%) agreed to participate. RESULTS: Alcohol (72.2%), tobacco (27.1%) and cannabis (15.2%) were most commonly reported. Eighty-nine participants reported moderate- or high-risk use of two substances, and a further 49 individuals reported moderate- or high-risk use of three or more substances. Across most substances, age, gender and employment status was associated with risky substance use, with higher likelihood of risk reported by males, unemployed and younger participants. Unemployment was also significantly associated with increased risk severity for both moderate and high-risk illicit use. DISCUSSIONS AND CONCLUSIONS: The rate of risky illicit and polysubstance use found here highlight the need more focused research in ED settings. The findings also provide support for more routine screening, and early intervention approaches; and suggest the need for active referral pathways through an alcohol and other drug consultation liaison service.

The utilization of allied and community health services by cancer patients living in regional and remote geographical areas in Australia.

INTRODUCTION: Cancer patients in Australia's Northern Territory (NT) face unique challenges to accessing cancer-related community and allied health services (referred here as 'health services'). This is in part due to the NT's unique geographic, socioeconomic and demographic profile. This paper describes the use of health services by cancer patients in the NT. METHODS: Adult cancer patients attending appointments at a cancer centre in Darwin, NT and who were diagnosed within the past five years were invited to participate in face-to-face interviews about their use of allied and community health services. A descriptive analysis of health services utilization was conducted. RESULTS: Of the 76 participants interviewed, 63% identified as non-Indigenous, 53% female and 45% lived in very remote areas. Mean age at interview was 58.7 years (SD 13.2). Overall, 82% of participants utilized at least one health service since their cancer diagnosis. All Indigenous participants used at least one service, while 28% of non-Indigenous participants did not use any health service. The services most frequently used by participants were community services (42%) and information sources (40%). CONCLUSION: The findings from this study suggest there is variation in the type of community and allied health services used by NT cancer patients across clinical and demographic groups (including Indigenous status). Further qualitative enquiry is needed to better understand this variation, which may reflect differences in service preference, accessibility, health literacy of patients or patient engagement. Such knowledge may inform service delivery improvements to better support cancer patients through their cancer care pathway.

Comparison of physical behavior estimates from three different thigh-worn accelerometers brands: a proof-of-concept for the Prospective Physical Activity, Sitting, and Sleep consortium (ProPASS).

BACKGROUND: Pooling data from thigh-worn accelerometers across multiple studies has great potential to advance evidence on the health benefits of physical activity. This requires harmonization of information on body postures, physical activity types, volumes and time patterns across different brands of devices. The aim of this study is to compare the physical behavior estimates provided by three different brands of thigh-worn accelerometers. METHODS: Twenty participants volunteered for a 7-day free-living measurement. Three accelerometers - ActiGraph GT3X+, Axivity AX3 and ActivPAL Micro4 - were randomly placed in a vertical line on the midsection of the right thigh. Raw data from each accelerometer was processed and classified into 8 physical activities and postures using the Acti4 software. Absolute differences between estimates and the respective coefficient of variation (CV) were calculated. RESULTS: We observed very minor differences between physical behavior estimates from three different accelerometer brands. When averaged over 24 h (1,440 min), the absolute difference (CV) between accelerometers were: 1.2 mins (0.001) for lying/sitting, 3.4 mins (0.02) for standing, 3.5 mins (0.06) for moving, 1.9 mins (0.03) for walking, 0.1 mins (0.19) for running, 1.2 mins (0.19) for stair climbing, 1.9 mins (0.07) for cycling. Moreover, there was an average absolute difference of 282 steps (0.03) per 24 h. CONCLUSIONS: Physical behaviors were classified with negligible difference between the accelerometer brands. These results support harmonization of data from different thigh-worn accelerometers across multiple cohorts when analyzed in an identical manner.

Evaluating changes in electronic gambling machine policy on user losses in an Australian jurisdiction.

BACKGROUND: Electronic gambling machines (EGMs) are in casinos and community venues (hotels and clubs) in all jurisdictions in Australia, except Western Australia (only in casino). EGMs have a range of features that can affect how people gamble, which can influence losses incurred by users. The Northern Territory Government recently changed two EGM policies - the introduction of note acceptors on EGMs in community venues, and an increase in the cap from 10 to 20 EGMs in hotels and 45 to 55 in clubs. This study evaluates two changes in EGM policy on user losses in community venues, and tracks changes in user losses per adult, EGM gambler, and EGM problem/moderate risk gambler between 2005 and 2015. METHODS: Trends in venue numbers, EGM numbers, user losses and user losses per EGM by venue type and size are presented to determine if EGM policy changes affected user losses. Data from the 2005 and 2015 NT gambling surveys are used to determine EGM user losses per adult, per EGM gambler, and per EGM problem and/or moderate risk gambler, with several assumptions applied. RESULTS: From 2010 (post smoking ban) to 2013 real user losses were stagnant, but from 2013 to 2017, real user losses in community venues increased 19, 9, 8 and 5% per annum, with increases higher in clubs and hotels with the maximum allowable number of EGMs. Over the same period user losses in the two casinos declined by 13%. Between 2005 and 2015, estimated user losses per EGM problem/moderate risk and problem gambler increased by 5 and 34% respectively. CONCLUSIONS: The analysis demonstrates that reductions in how much money gamblers can insert into an EGM (load-up limit), and/or the abolition of note acceptors, and reductions in the number of EGMs in venues is likely to reduce harm from EGM use. Given the demonstrated inability for Australian jurisdictions to identify and implement effective harm prevention and minimisation interventions, a national approach to gambling regulation in Australia may be desirable. Similarly, national co-ordination of research, particularly on EGMs and online betting is required to better understand changes in gambling policy on related harms.

Aldehyde dehydrogenase 3A1 activation prevents radiation-induced xerostomia by protecting salivary stem cells from toxic aldehydes.

Xerostomia (dry mouth) is the most common side effect of radiation therapy in patients with head and neck cancer and causes difficulty speaking and swallowing. Since aldehyde dehydrogenase 3A1 (ALDH3A1) is highly expressed in mouse salivary stem/progenitor cells (SSPCs), we sought to determine the role of ALDH3A1 in SSPCs using genetic loss-of-function and pharmacologic gain-of-function studies. Using DarkZone dye to measure intracellular aldehydes, we observed higher aldehyde accumulation in irradiated Aldh3a1-/- adult murine salisphere cells and in situ in whole murine embryonic salivary glands enriched in SSPCs compared with wild-type glands. To identify a safe ALDH3A1 activator for potential clinical testing, we screened a traditional Chinese medicine library and isolated d-limonene, commonly used as a food-flavoring agent, as a single constituent activator. ALDH3A1 activation by d-limonene significantly reduced aldehyde accumulation in SSPCs and whole embryonic glands, increased sphere-forming ability, decreased apoptosis, and improved submandibular gland structure and function in vivo after radiation. A phase 0 study in patients with salivary gland tumors showed effective delivery of d-limonene into human salivary glands following daily oral dosing. Given its safety and bioavailability, d-limonene may be a good clinical candidate for mitigating xerostomia in patients with head and neck cancer receiving radiation therapy.

Scalable synthesis of bryostatin 1 and analogs, adjuvant leads against latent HIV.

Bryostatin 1 is an exceedingly scarce marine-derived natural product that is in clinical development directed at HIV/AIDS eradication, cancer immunotherapy, and the treatment of Alzheimer's disease. Despite this unique portfolio of indications, its availability has been limited and variable, thus impeding research and clinical studies. Here, we report a total synthesis of bryostatin 1 that proceeds in 29 total steps (19 in the longest linear sequence, >80% average yield per step), collectively produces grams of material, and can be scaled to meet clinical needs (~20 grams per year). This practical solution to the bryostatin supply problem also opens broad, facile, and efficient access to derivatives and potentially superior analogs.

Characterisation of the canine faecal virome in healthy dogs and dogs with acute diarrhoea using shotgun metagenomics.

The virome has been increasingly investigated in numerous animal species and in different sites of the body, facilitating the identification and discovery of a variety of viruses. In spite of this, the faecal virome of healthy dogs has not been investigated. In this study we describe the faecal virome of healthy dogs and dogs with acute diarrhoea in Australia, using a shotgun metagenomic approach. Viral sequences from a range of different virus families, including both RNA and DNA families, and known pathogens implicated in enteric disease were documented. Twelve viral families were identified, of which four were bacteriophages. Eight eukaryotic viral families were detected: Astroviridae, Coronaviridae, Reoviridae, Picornaviridae, Caliciviridae, Parvoviridae, Adenoviridae and Papillomaviridae. Families Astroviridae, Picornaviridae and Caliciviridae were found only in dogs with acute diarrhoea, with Astroviridae being the most common family identified in this group. Due to its prevalence, characterisation the complete genome of a canine astrovirus was performed. These studies indicate that metagenomic analyses are useful for the investigation of viral populations in the faeces of dogs. Further studies to elucidate the epidemiological and biological relevance of these findings are warranted.

The Effect of Pack Warning Labels on Quitting and Related Thoughts and Behaviors in a National Cohort of Aboriginal and Torres Strait Islander Smokers.

INTRODUCTION: The high prevalence of smoking among Aboriginal and Torres Strait Islander people in Australia (39%) contributes substantially to health inequalities. This study assesses the impact of warning labels on quitting and related thoughts and behaviors for Aboriginal and Torres Strait Islander smokers. METHODS: Participants were recruited from communities served by 34 Aboriginal Community Controlled Health Services and communities in the Torres Strait, Australia, using quota sampling. A cohort of 642 daily/weekly smokers completed relevant questions at baseline (April 2012-October 2013) and follow-up (August 2013-August 2014). RESULTS: We considered three baseline predictor variables: noticing warning labels, forgoing cigarettes due to warning labels ("forgoing") and perceiving labels to be effective. Forgoing increased significantly between surveys only for those first surveyed prior to the introduction of plain packs (19% vs. 34%); however, there were no significant interactions between forgoing cigarettes and the introduction of new and enlarged graphic warning labels on plain packaging in any model. Forgoing cigarettes predicted attempting to quit (adjusted odds ratio [AOR]: 1.45, 95% confidence interval [CI]: 1.02-2.06) and, among those who did not want to quit at baseline, wanting to quit at follow-up (AOR: 3.19, 95% CI: 1.06-9.63). Among those less worried about future health effects, all three variables predicted being very worried at follow-up. Often noticing warning labels predicted correct responses to questions about health effects that had featured on warning labels (AOR: 1.84, 95% CI: 1.20-2.82) but not for those not featured. CONCLUSIONS: Graphic warning labels appear to have a positive impact on the understanding, concerns and motivations of Aboriginal and Torres Strait Islander smokers and, through these, their quit attempts. IMPLICATIONS: Graphic warning labels are likely to be effective for Aboriginal and Torres Strait Islander smokers as they are for the broader Australian population.

Predictors of wanting to quit in a national sample of Aboriginal and Torres Strait Islander smokers.

OBJECTIVE: To describe factors that predict wanting to quit smoking in a national sample of Aboriginal and Torres Strait Islander people. DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes (TATS) project used a quota sampling design to recruit participants from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait. Baseline survey data were collected from 1643 current smokers between April 2012 and October 2013. MAIN OUTCOME MEASURE: Wanting to quit smoking. RESULTS: More than two-thirds of smokers (70%) said they want to quit. Many factors were associated with wanting to quit, including past quitting activity. Interest in quitting was lower among men and smokers from economically disadvantaged areas, but there was no difference by age, remoteness or other measures of economic disadvantage. Attitudes and beliefs negatively associated with wanting to quit included enjoying smoking and believing quitting to be very difficult, and those positively associated included regretting ever starting to smoke, perceiving that local Aboriginal and Torres Strait Islander community leaders disapprove of smoking, believing non-smokers set a good example to children, worrying about future smoking-related health effects and believing quitting to be beneficial. Reporting support from family and friends was predictive of wanting to quit, but factors related to smoking in the social network were not. Associations with health and wellbeing were mixed. While most tobacco control policy exposure variables were positively associated with wanting to quit, two - receiving advice to quit from a health professional, and recall of targeted anti-tobacco advertising - appeared to have an effect that extended beyond influencing relevant attitudes and beliefs. CONCLUSION: Interest in quitting among Aboriginal and Torres Strait Islander smokers appears to be influenced by a broad range of factors, highlighting the importance of taking a comprehensive approach to tobacco control. Advice from health professionals and targeted advertising appear to be important intervention strategies.

Past quit attempts in a national sample of Aboriginal and Torres Strait Islander smokers.

OBJECTIVES: To describe past attempts to quit smoking in a national sample of Aboriginal and Torres Strait Islander people, and to compare their quitting activity with that in the general Australian population. DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes (TATS) project used a quota sampling design to recruit participants from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait. We surveyed 1643 smokers and 78 recent quitters between April 2012 and October 2013. Baseline results for daily smokers (n = 1392) are compared with results for daily smokers (n = 1655) from Waves 5 to 8.5 (2006-2012) of the Australian International Tobacco Control Policy Evaluation Project (ITC Project). MAIN OUTCOME MEASURES: Ever having tried to quit, tried to quit in the past year, sustained a quit attempt for 1 month or more. RESULTS: Compared with the general population, a smaller proportion of Aboriginal and Torres Strait Islander daily smokers had ever tried to quit (TATS, 69% v ITC, 81.4%), but attempts to quit within the past year were similar (TATS, 48% v ITC, 45.7%). More Aboriginal and Torres Strait Islander daily smokers than those in the general population reported sustaining past quit attempts for short periods only. Aboriginal and Torres Strait Islander smokers whose local health services had tobacco control resources were more likely to have tried to quit, whereas men and people who perceived they had experienced racism in the past year were less likely. Younger smokers, those who had gone without essentials due to money spent on smoking, and those who were often unable to afford cigarettes were more likely to have tried to quit in the past year, but less likely to have ever sustained an attempt for 1 month or more. Smokers who were unemployed, those who had not completed Year 12 and those from remote areas were also less likely to sustain a quit attempt. CONCLUSIONS: Existing comprehensive tobacco control programs appear to be motivating Aboriginal and Torres Strait Islander smokers to quit but do not appear to overcome challenges in sustaining quit attempts, especially for more disadvantaged smokers and those from remote areas.

Smoke-free homes and workplaces of a national sample of Aboriginal and Torres Strait Islander people.

OBJECTIVE: To examine Aboriginal and Torres Strait Islander people's protection from second-hand smoke at home and work. DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes project surveyed 2522 Aboriginal and Torres Strait Islander people from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait, using quota sampling, from April 2012 to October 2013. We made comparisons with data from Australian smokers in the International Tobacco Control Policy Evaluation Project (ITC Project), collected from either July 2010 to May 2011 or September 2011 to February 2012. MAIN OUTCOME MEASURES: Whether smoking was not allowed anywhere in the home, or not allowed in any indoor area at work. RESULTS: More than half (56%) of Aboriginal and Torres Strait Islander smokers and 80% of non-smokers reported that smoking was never allowed anywhere in their home. Similar percentages of daily smokers in our sample and the Australian ITC Project data reported bans. Most employed Aboriginal and Torres Strait Islander daily smokers (88%) reported that smoking was not allowed in any indoor area at work, similar to the Australian ITC Project estimate. Smokers working in smoke-free workplaces were more likely to have smoke-free homes than those in workplaces where smoking was allowed indoors (odds ratio, 2.85; 95% CI, 1.67-4.87). Smokers who lived in smoke-free homes were more likely to have made a quit attempt in the past year, to want to quit, and to have made quit attempts of 1 month or longer. CONCLUSION: Most Aboriginal and Torres Strait Islander people are protected from second-hand smoke at work, and similar proportions of Aboriginal and Torres Strait Islander smokers and other Australian smokers do not allow smoking inside their homes.

Dependence in a national sample of Aboriginal and Torres Strait Islander daily smokers.

OBJECTIVES: To examine indicators of nicotine dependence in a national sample of Aboriginal and Torres Strait Islander daily smokers and their association with sustaining a quit attempt for at least 1 month, and to make comparisons with a national sample of Australian daily smokers. DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes project used a quota sampling design to recruit 1392 daily smokers from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait from April 2012 to October 2013. These were compared with 1010 daily smokers from the general Australian population surveyed by the International Tobacco Control Policy Evaluation Project from September 2011 to February 2012. MAIN OUTCOME MEASURES: Cigarettes per day (CPD), time to first cigarette, Heaviness of Smoking Index (HSI), other indicators of dependence, and whether smokers had ever sustained a quit attempt for at least 1 month. RESULTS: There was little difference in the mean HSI scores for Aboriginal and Torres Strait Islander and other Australian daily smokers. A higher proportion of Aboriginal and Torres Strait Islander daily smokers smoked ≤ 10 CPD (40% v 33.4%), but more also smoked their first cigarette within 30 minutes of waking (75% v 64.6%). Lower proportions of Aboriginal and Torres Strait Islander smokers reported having strong urges to smoke at least several times a day (51% v 60.7%) or that it would be very hard to quit (39% v 47.9%). Most Aboriginal and Torres Strait Islander smokers reported experiencing difficulties during their most recent quit attempt. All indicators of dependence, except CPD and strong urges, were positively associated with not having made a sustained quit attempt. Reported difficulties during the most recent quit attempt were more strongly associated with being unable to sustain quit attempts than were traditional measures of dependence. CONCLUSION: Aboriginal and Torres Strait Islander smokers' experiences of past attempts to quit may be more useful than conventional indicators of nicotine dependence in understanding their dependence.

Smoking-related knowledge and health risk beliefs in a national sample of Aboriginal and Torres Strait Islander people.

OBJECTIVES: To describe general knowledge and perceived risk of the health consequences of smoking among Aboriginal and Torres Strait Islander people; and to assess whether knowledge varies among smokers and whether higher knowledge and perceived risk are associated with quitting. DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes project used quota sampling to recruit participants from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait. Baseline survey data were collected from 2522 Aboriginal and Torres Strait Islander adults from April 2012 to October 2013. MAIN OUTCOME MEASURES: Knowledge of direct effects of smoking and harms of second-hand smoke (SHS), risk minimisation, health worry, and wanting and attempting to quit. RESULTS: Most Aboriginal and Torres Strait Islander participants who were daily smokers demonstrated knowledge that smoking causes lung cancer (94%), heart disease (89%) and low birthweight (82%), but fewer were aware that it makes diabetes worse (68%). Similarly, almost all daily smokers knew of the harms of SHS: that it is dangerous to non-smokers (90%) and children (95%) and that it causes asthma in children (91%). Levels of knowledge among daily smokers were lower than among non-daily smokers, ex-smokers and never-smokers. Among smokers, greater knowledge of SHS harms was associated with health worry, wanting to quit and having attempted to quit in the past year, but knowledge of direct harms of smoking was not. CONCLUSION: Lack of basic knowledge about the health consequences of smoking is not an important barrier to trying to quit for Aboriginal and Torres Strait Islander smokers. Framing new messages about the negative health effects of smoking in ways that encompass the health of others is likely to contribute to goal setting and prioritising quitting among Aboriginal and Torres Strait Islander people.

Research methods of Talking About The Smokes: an International Tobacco Control Policy Evaluation Project study with Aboriginal and Torres Strait Islander Australians.

OBJECTIVE: To describe the research methods and baseline sample of the Talking About The Smokes (TATS) project. DESIGN: The TATS project is a collaboration between research institutions and Aboriginal community-controlled health services (ACCHSs) and their state and national representative bodies. It is one of the studies within the International Tobacco Control Policy Evaluation Project, enabling national and international comparisons. It includes a prospective longitudinal study of Aboriginal and Torres Strait Islander smokers and recent ex-smokers; a survey of non-smokers; repeated cross-sectional surveys of ACCHS staff; and descriptions of the tobacco policies and practices at the ACCHSs. Community members completed face-to-face surveys; staff completed surveys on paper or online. We compared potential biases and the distribution of variables common to the main community baseline sample and unweighted and weighted results of the 2008 National Aboriginal and Torres Strait Islander Social Survey (NATSISS). The baseline survey (Wave 1) was conducted between April 2012 and October 2013. SETTING AND PARTICIPANTS: 2522 Aboriginal and Torres Strait Islander people in 35 locations (the communities served by 34 ACCHSs and one community in the Torres Strait), and 645 staff in the ACCHSs. MAIN OUTCOME MEASURES: Sociodemographic and general health indicators, smoking status, number of cigarettes smoked per day and quit attempts. RESULTS: The main community baseline sample closely matched the distribution of the Aboriginal and Torres Strait Islander population in the weighted NATSISS by age, sex, jurisdiction and remoteness. There were inconsistent differences in some sociodemographic factors between our sample and the NATSISS: our sample had higher proportions of unemployed people, but also higher proportions who had completed Year 12 and who lived in more advantaged areas. In both surveys, similar percentages of smokers reported having attempted to quit in the past year, and daily smokers reported similar numbers of cigarettes smoked per day. CONCLUSION: The TATS project provides a detailed and nationally representative description of Aboriginal and Torres Strait Islander smoking behaviour, attitudes, knowledge and exposure to tobacco control activities and policies, and their association with quitting.

Personal attitudes towards smoking in a national sample of Aboriginal and Torres Strait Islander smokers and recent quitters.

OBJECTIVES: To describe attitudes towards smoking in a national sample of Aboriginal and Torres Strait Islander smokers and recent quitters and assess how they are associated with quitting, and to compare these attitudes with those of smokers in the general Australian population. DESIGN, SETTING AND PARTICIPANTS: The Talking About The Smokes project used a quota sampling design to recruit participants from communities served by 34 Aboriginal community-controlled health services and one community in the Torres Strait. We surveyed 1392 daily smokers, 251 non-daily smokers and 78 recent quitters from April 2012 to October 2013. MAIN OUTCOME MEASURES: Personal attitudes towards smoking and quitting, wanting to quit, and attempting to quit in the past year. RESULTS: Aboriginal and Torres Strait Islander daily smokers were less likely than daily smokers in the general Australian population to report enjoying smoking (65% v 81%) and more likely to disagree that smoking is an important part of their life (49% v 38%); other attitudes were similar between the two groups. In the Aboriginal and Torres Strait Islander sample, non-daily smokers generally held less positive attitudes towards smoking compared with daily smokers, and ex-smokers who had quit within the past year reported positive views about quitting. Among the daily smokers, 78% reported regretting starting to smoke and 81% reported spending too much money on cigarettes, both of which were positively associated with wanting and attempting to quit; 32% perceived smoking to be an important part of their life, which was negatively associated with both quit outcomes; and 83% agreed that smoking calms them down when stressed, which was not associated with the quitting outcomes. CONCLUSIONS: Aboriginal and Torres Strait Islander smokers were less likely than those in the general population to report positive reasons to smoke and held similar views about the negative aspects, suggesting that factors other than personal attitudes may be responsible for the high continuing smoking rate in this population.
