Drinking and swimming around waterways: The role of alcohol, sensation-seeking, peer influence and risk in young people.

The role of individual and sociocultural factors contributing to drowning risk for young adults is complex and poorly understood. This study examined the relationship between behaviour in and around waterways and: 1) alcohol consumption; 2) resistance to peer influence; 3) sensation-seeking; 4) perception of risk among people aged 15-24 in Western Australia. A cross-sectional online survey was conducted at three time-points with a convenience sample. Predictor variables included: Alcohol Use Disorder Identification Test Consumption (AUDIT_C); Resistance to Peer Influence; Brief Sensation Seeking scale; Benthin's Perception of risk. Pearson chi-squared tests determined the association between demographic and predictor variables. Logistic regression explored influence of potential predictor variables on behaviour in and around water. The final sample (n = 730) participants, consisted of females (n = 537, 74.5%), metropolitan dwelling (n = 616, 84.4%), and attended university (n = 410, 56.9%). Significant associations were found for those who swum after drinking alcohol compared with those that had not by age, gender, education. For every 1-unit increase in AUDIT-C participants were 60% more likely to swim after drinking (OR 95% CI 1.60 1.44-1.78). Participants who considered an adverse event serious were 15% less likely to have swum after drinking alcohol (OR 0.85 95% CI 0.73-0.99). The complex relationship between social participation in activities in and around waterways, higher drowning rates, propensity for risk, and the meaning young adults attach to risk locations and practices present unique challenges for drowning prevention research. Findings should be used to improve the awareness and education components of future youth water safety strategies in high-income settings.

Would you Find Thirty online? Website use in a Western Australian physical activity campaign.

ISSUE ADDRESSED: Mass media campaigns have used a range of traditional media (television, radio and print) to communicate health messages. In the past decade the Internet has added to these traditional methods with Web 2.0, smart phone technology and interactive media. 'Find Thirty every day(®)', a Western Australia population-wide mass media campaign delivered over 2 years, used a combination of traditional mass media, a website, online resources and banner advertising. The aim of the present study is to describe the use of the Find Thirty every day(®) website during the campaign media activities of May 2008-June 2010. METHODS: Cross-sectional self-reported survey data were collected from a random sample of adults using a computer-assisted telephone interview over the period February-March 2010. Objective online analytical measures of unique visits to the Find Thirty every day(®) website were collected between June 2008 and June 2010. RESULTS: Monthly visitors to the Find Thirty every day(®) website increased from 3193 in 2009 to 4374 in 2010. During the last two media waves (October 2009 and February 2010), site visits were 5388 and 5272 per month, respectively. CONCLUSION: The impact of the Find Thirty every day(®) website was a positive outcome, considering the minimal online presence. SO WHAT? Health communication campaign planners should maximise the potential synergy of traditional mass media and new social media in future campaigns. Accordingly, a multidisciplinary approach that includes communication researchers, experts in information systems and a creative team experienced in online environments will need to be the way forward.

Does neighbourhood walkability moderate the effects of mass media communication strategies to promote regular physical activity?

BACKGROUND: Mass media campaigns are widely used in Australia and elsewhere to promote physical activity among adults. Neighbourhood walkability is consistently shown to be associated with walking and total activity. Campaigns may have different effects on individuals living in high and low walkable neighbourhoods. PURPOSE: The purpose of this study is to compare pre- and post-campaign cognitive and behavioural impacts of the Heart Foundation's Find Thirty every day® campaign, in respondents living in high and lower walkable neighbourhoods. METHODS: Pre- and post-campaign cross-sectional survey data were linked with objectively measured neighbourhood walkability. Cognitive and behavioural impacts were assessed using logistic regression stratified by walkability. RESULTS: Cognitive impacts were significantly higher post-campaign and consistently higher in respondents in high compared with lower walkable neighbourhoods. Post campaign sufficient activity was significantly higher and transport walking significantly lower, but only in residents of lower walkable areas. CONCLUSIONS: Cognitive impacts of mass media physical activity campaigns may be enhanced by living in a more walkable neighbourhood.

Occupational risk factors for prostate cancer and benign prostatic hyperplasia: a case-control study in Western Australia.

OBJECTIVE: To assess the association of selected occupational exposures with risk of prostate cancer and with risk of benign prostatic hyperplasia (BPH). METHODS: This population-based case-control study recruited 606 men with a diagnosis of confirmed prostate cancer, 400 men who had undergone their first prostatectomy for BPH and 471 male controls randomly selected from the electoral roll between 1 August 2001 and 1 October 2002 in Western Australia. chi(2) tests and logistic regressions were used for univariate and multivariate analyses to investigate the association of the two outcomes with occupational exposure to pesticides, fertilisers, metals, wood dust, oils, diesel exhaust and polyaromatic hydrocarbons (PAHs). RESULTS: Exposure to toxic metals at a non-substantial level increased the risk of BPH (odds ratio (OR) 1.39, 95% confidence interval (CI) 1.1 to 1.84) and led to a non-significant excess risk of prostate cancer (OR 1.25, 95% CI 0.96 to 1.61). Non-significant excess risks were observed for prostate cancer after exposure to oils other than mineral oil (OR 1.54, 95% CI 0.95 to 2.51) and for BPH after exposure to PAHs (OR 1.20, 95% CI 0.91 to 1.58). A non-statistically significant protective effect for prostate cancer was seen after exposure to organophosphate pesticides (OR 0. 69, 95% CI 0.43 to 1.12). No other associations were found for either prostate cancer or BPH and no dose-response relationships were seen for the exposures investigated. CONCLUSIONS: These results do not provide evidence that any of the occupational factors examined are risk factors for either prostate cancer or BPH.
