Getting there together: highlights, challenges and opportunities for tobacco control in the Oceania region.

BACKGROUND: The paper focuses on the geographical region of Oceania. We highlight the tobacco control leadership demonstrated in this region and describe the challenges and opportunities to achieving country-specific smoke-free goals. RESULTS: Significant achievements include smoke-free nation goals, world-leading initiatives such as plain packaging, and a bold plan by New Zealand to reduce the retail availability of smoked tobacco products and remove virtually all the nicotine from cigarettes and rolling tobacco. There are significant challenges and opportunities before reaching smoke-free status including implementation pathways requiring strong governance and leadership and compliance monitoring and enforcement. CONCLUSIONS: We conclude that achieving a smoke-free Oceania is possible through already existing bold country and regional smoke-free goals, excellent tobacco control leadership, experience and resources, and an understanding of how to work collectively. However, a commitment to focus tobacco control efforts regionally is required to achieve a smoke-free Oceania together.

Human leptospirosis in The Federated States of Micronesia: a hospital-based febrile illness survey.

BACKGROUND: Human leptospirosis is an emerging infectious disease of global significance, and is endemic to several countries in the Pacific. Zoonotic transmission dynamics combined with diagnostic challenges lead to difficulties in prevention and identification of cases. The Federated States of Micronesia (FSM) lacks surveillance data for human leptospirosis. This hospital-based serologic survey sought to estimate the burden of leptospirosis, collect information relating to associated factors, and assess the leptospirosis point-of-care rapid diagnostic test (RDT) commonly used in FSM. METHODS: A four-month hospital-based survey was conducted in Pohnpei State, FSM in 2011. Patients with undifferentiated fevers presenting to hospital were referred for enrolment by physicians. Consenting participants provided paired blood specimens 10-30 days apart, and responded to interview questions regarding demographics, clinical symptoms, exposure to animals, and environmental exposure. Blood samples were subjected to immunochromatographic RDT and confirmed by microscopic agglutination test (MAT). RESULTS: Of 54 participants tested by MAT, 20.4% (95% confidence interval [CI] 10.1-30.6%) showed serologic evidence of acute infection. Occupation student (odds ratio [OR], 17.5; 95% CI: 1.9-161.1) and recreational gardening (OR, 8.6; 95% CI: 1.0-73.8), identified by univariate logistic regression, were associated with infection. The local rapid diagnostic test (RDT) performed with a sensitivity of 69.2 (42.3-89.3 CI) and specificity of 90.0 (81.6-95.6 CI) compared to MAT. CONCLUSIONS: This study demonstrated a high burden of leptospirosis in Pohnpei. Further work is warranted to identify additional risk factors and opportunities to control leptospirosis in Pohnpei and other Pacific settings.

Occupational sun protection: workplace culture, equipment provision and outdoor workers' characteristics.

OBJECTIVES: The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. METHODS: The present study used a clustered survey design with randomly identified employers in nine occupations. Employees provided questionnaire measures of demographics, personal characteristics (skin type, skin cancer risk perceptions, tanning attitudes, sun-exposure knowledge), personal occupational sun protection practices (exposure reduction, use of sun-protective clothing, sunscreen and shade), workplace sun-protective equipment provision and perceived workplace sun-safety culture. Summative scores were calculated for attitudes, knowledge, workplace provision and culture. A multivariable model was built with worker and workplace variables as plausible predictors of personal sun protection. RESULTS: In this study, 1,061 workers (69% participation) from 112 workplaces provided sufficient information for analysis. Sex, age, prioritized ethnicity, education and risk perception differed significantly between occupational groups (p<0.001), as did workers' sun-protective practices and workplace sun-protection equipment provision and supportive culture. After adjustment, each one-point increase in Workplace Sun-safety Culture 2013Score (range 12 points) was associated with a 0.16 higher Personal Sun-Protection Score (p<0.001), and each one-point increase in Workplace Provision Score (range 4 points) was associated with a 0.14 higher score (p<0.001). Sun Protection Score was significantly associated with skin response to sun exposure (p<0.001), female sex (p=0.021), tanning attitudes (p=0.022) and occupation (p=0.049), but not ethnicity, age education, knowledge or skin cancer risk perception. CONCLUSIONS: Protective equipment provision and sun-protective workplace culture are promising components for the development of comprehensive programmes to improve outdoor workers' sun-protective practices.

Outdoor workers' perceptions of the risks of excess sun-exposure.

OBJECTIVES: To describe the pattern of associations with sunscreen use of sun protection attitudes and knowledge in a large sample of New Zealand outdoor workers. We also examined the relationship between perceived skin type and perceived risk of developing skin cancer. METHODS: Outdoor workers from nine occupational groups (n=1,131) completed a questionnaire, which included measures of skin cancer related risk perceptions, knowledge and sunscreen use. RESULTS: Sunscreen use was associated with perceived prioritization of sun-protection, concern about sun-exposure, knowledge about the effects of sun-exposure and perceived supportive workplace culture. These variables accounted for 37% of the variation in sunscreen use. Maori, younger workers and forestry workers least likely to report sunscreen use and sun-exposure risk perception. CONCLUSIONS: Interventions that strengthen knowledge about risks and values of sun protection are likely to increase sun protection efforts. However, interventions for outdoor workers need to take into account potential socio-demographic, personal and workplace influences are required to prevent the risk of developing non-melanoma skin cancers within this population group.

The influence of smoking imagery on the smoking intentions of young people: testing a media interpretation model.

PURPOSE: To assess a theoretical model of adolescents' exposure to films, perceptions of smoking imagery in film, and smoking intentions. METHODS: A structured questionnaire was completed by 3041 Year 8 (aged 12 years) and Year 12 (aged 16 years) students from 25 schools in Auckland, New Zealand. The survey assessed the relationships among exposure to films, attitudes about smoking imagery, perceptions of smoking prevalence and its acceptability, and expectations of smoking in the future. Measures included exposure to films, perceived pervasiveness of, and nonchalant attitudes about smoking imagery, identification of positive smoker stereotypes in films, perceived smoking prevalence, judgment of smoking acceptability, and smoking expectations. Path analytic techniques, using multiple regression analyses, were used to test the pattern of associations identified by the media interpretation model. RESULTS: Hierarchical regression analyses revealed that film exposure predicted higher levels of perceived smoking prevalence, perceived imagery pervasiveness, and nonchalant attitudes about smoking imagery. Nonchalant attitudes, identification of positive smoker stereotypes, and perceived smoking prevalence predicted judgments of smoking acceptability. Acceptability judgments, identification of positive stereotypes, and perceived smoking prevalence were all positively associated with smoking expectations. The media interpretation model accounted for 24% of the variance in smoking expectations within the total sample. CONCLUSIONS: Smoking imagery in film may play a role in the development of smoking intentions through inflating the perception of smoking prevalence and presenting socially attractive images.

Interpretations of smoking in film by older teenagers.

Research testifies that images of tobacco use in popular films are highly pervasive and typically glamorised. There are concerns that these images may promote motivations to smoke in adolescents, but little is known about how these images are interpreted by members of this age group. A qualitative study was conducted to explore how older teenagers interpret and decode smoking imagery in film. This study builds on earlier work with a younger age group (12 and 13 years) to explore how various interpretations of smoking imagery shape and support common understandings about smoking among older teenagers. Data were collected through focus groups. Eighty-eight 16 and 17 year old students were interviewed at school. Participants discussed their recollections of and responses to recently viewed films. Older teens were receptive to smoking imagery when it was used in a credible manner to portray an emotional state, sub-culture affiliation, and lifestyle. Experience as a smoker appeared to inflate the credibility of realistic smoking images, particularly those presented in gritty realism/drama film. Older teens perceived realistic images, as opposed to stereotypical images, as a salient reference to their own lives. Stereotypical images were also readily recalled and appeared to perform an important role in supporting misconceptions about smoking and contributing to popular ideologies about tobacco use. Stereotypical images presented in comedy and action genre also serve to present paradoxical and contradictory messages about tobacco use. In particular, participants recalled tobacco use in film as associated with stress and anxiety, drug use, and seduction. Film images of tobacco use in specific contexts appear to hold specific and significant meanings for older teens. Realistic images offered salient representations of the perceived reality of smoking for this group. Pervasive and credible smoking scenes in film may offer support and reassurance to older teens who currently smoke or hold ambivalent views about smoking. Consistent with younger adolescents, older teens presented a predominantly nonchalant response to smoking imagery in film, which is a powerful indicator of the pervasiveness and acceptability of smoking in general. In contrast with younger adolescent, older teens tend to draw upon their own experience with tobacco use when interpreting smoking images in film.
