Closing the gaps in tobacco endgame evidence: a scoping review.

OBJECTIVE: Tobacco endgame policies aim to rapidly and permanently reduce smoking to minimal levels. We reviewed evidence syntheses for: (1) endgame policies, (2) evidence gaps, and (3) future research priorities. DATA SOURCES: Guided by JBI scoping review methodology, we searched five databases (PubMed, CINAHL, Scopus, Embase and Web of Science) for evidence syntheses published in English since 1990 on 12 policies, and Google for publications from key national and international organisations. Reference lists of included publications were hand searched. STUDY SELECTION: Two reviewers independently screened titles and abstracts. Inclusion criteria were broad to capture policy impacts (including unintended), feasibility, public and stakeholder acceptability and other aspects of policy implementation. DATA EXTRACTION: We report the results according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. DATA SYNTHESIS: Eight policies have progressed to evidence synthesis stage (49 publications): mandatory very low nicotine content (VLNC) standard (n=26); product standards to substantially reduce consumer appeal or remove the most toxic products from the market (n=1); moving consumers to reduced risk products (n=8); tobacco-free generation (n=4); ending sales (n=2); sinking lid (n=2); tax increases (n=7); and restrictions on tobacco retailers (n=10). Based on published evidence syntheses, the evidence base was most developed for a VLNC standard, with a wide range of evidence synthesised. CONCLUSIONS: VLNC cigarettes have attracted the most attention, in terms of synthesised evidence. Additional focus on policies that reduce the availability of tobacco is warranted given these measures are being implemented in some jurisdictions.

Cigarette smoking and e-cigarette use among university students in Queensland, Australia and New Zealand: results of two cross-sectional surveys.

OBJECTIVES: Examine the patterns of cigarette smoking and e-cigarette use (vaping), the perceived harm of e-cigarettes compared with tobacco cigarettes, and associations between smoking and vaping with student characteristics. DESIGN: Cross-sectional studies. SETTING: The University of Queensland (UQ), Australia and eight New Zealand (NZ) universities. PARTICIPANTS: Students at UQ: 4957 (70.8% aged <25 years, 63.0% women) and NZ: 1854 (82.5% aged <25 years, 60.1% women). METHODS: Χ2 tests compared smoking by age and gender, and vaping by age, gender and smoking status. Two-sided p<0.05 was considered significant and 95% CIs reported where appropriate. Multinomial logistic regression examined associations between smoking and vaping (exclusive smoking, exclusive vaping, dual use and non-use) with age, gender and student type (domestic vs international). RESULTS: Smoking (UQ vs NZ, 95% CI): ever 45.2% (43.8% to 46.6%) vs 50.0% (47.7% to 52.3%), current 8.9% (8.1% to 9.7%) vs 10.4% (9.1% to 11.9%) and daily 5.2% (4.6% to 5.8%) vs 5.6% (4.6% to 6.7%), and not smoking in indoor 98.3% vs 87.7% or outdoor smoke-free spaces 83.8% vs 65.3%.Vaping (UQ vs NZ, 95% CI): ever 20.9% (19.8% to 22.1%) vs 37.6% (35.4% to 39.9%), current 1.8% (1.5% to 2.2%) vs 6.5% (5.4% to 7.7%) and daily 0.7% (0.5% to 1.0%) vs 2.5% (1.9% to 3.4%), and not vaping in indoor 91.4% vs 79.6% or outdoor smoke-free spaces 84.4% vs 71.3%. Of respondents, 71.7% (70.3% to 73.2%) vs 75.3% (72.9% to 77.6%) perceived e-cigarettes as less harmful than tobacco cigarettes.Men were more likely than women to smoke and vape, and to believe that e-cigarettes are less harmful. Regression models containing all predictors for smoking and vaping were significant and the effect of gender was significant for dual use, exclusive smoking and exclusive vaping (all p<0.01). Men had higher odds for smoking, vaping or dual use. CONCLUSIONS: Results suggest significant differences in patterns of smoking and vaping of university students in Australia and NZ, and a strong influence of gender on smoking and vaping.

Is open defaecation in outdoor recreation and camping areas a public health issue in Australia? A literature review.

ISSUE ADDRESSED: In Australia, natural areas used for outdoor recreation activities or camping often have limited or no sanitation infrastructure. Recreationist and campers may use open defaecation practices where toilets are not provided. Contaminated soils and watercourses are associated with gastrointestinal illnesses. This review aims to determine if open defaecation is a public health issue in outdoor recreation and camping areas in Australia. METHOD: A literature review was conducted using the following search engines: CINAHL, Informit Database, Scopus, ProQuest Science & Technology, Medline (Ovid) and EBSCOhost. Inclusion criteria for this review were both experimental and observational research designs for studies describing the public health issues associated with open defaecation practice. RESULTS: Out of 12 147 papers identified, only three studies met the inclusion criteria, showing a lack of research into this area. Included were two studies that addressed human waste management practices in outdoor environments and the breakdown of human waste in alpine regions of Tasmania. The third study measured water contamination at a freshwater beach on K'gari-Fraser Island, Queensland. Visitors to natural areas are potentially at high risk of illness due to exposure to faecal contamination from other visitors using unsafe open defaecation practices in high-use camping areas. CONCLUSION: The limited number of studies addressing open defaecation in the outdoor recreation and camp areas in Australia indicates this review is a starting point to identify critical areas that may be of concern when managing visitors in an outdoor recreation setting. This review recommends investigating barriers and enablers motivating human disposal waste in these settings to help formulate health promotion content; environmental management policies related to sanitation and hygiene should be also underpinned by public health policy; and providing appropriate sanitation options depending on the ecological and visitor numbers to natural areas. SO WHAT-RELEVANCE OF FINDINGS: Outdoor recreation activities offer physical and mental health benefits for communities. The popularity of outdoor recreation activities is on the increase in Australia. With the rise in visitation to natural areas, management of human waste needs to be addressed to reduce the public health risk of illness.
