Abstract
INTRODUCTION School holidays are a known period of increased risk of paediatric drowning. However, the risk of coastal death for all age groups is unknown. METHODS This case-control study aimed to identify high-risk demographics and behaviours relating to coastal deaths during the school holidays. We address this knowledge gap by comparing unintentional coastal deaths (drowning deaths and other coastal fatalities) in Australia between 1 July 2004-30 June 2021 to a survey sample representative of the Australian population. RESULTS School holidays increased the risk of coastal death increased overall by 1.39 times (95% CI 1.32 to 146, p=0.00019). This increased risk differed across activities, behaviours and demographics. Few between-group differences were detected, indicating that school holidays pose an increased risk to the wider Australian population on the coast, regardless of demographics and practices. Increased school holiday mortality risk was identified broadly across groups, but notably for young adults (risk ratio, RR 1.41, 95% CI 1.31 to 1.53, p<0.001), when attempting a rescue (RR 1.85, 95% CI 1.42 to 2.39, p=0.0002), scuba diving (RR 1.82, 95% CI 1.48 to 2.23, p<0.0001) and swimming/wading (RR 1.72, 95% CI 1.56 to 1.89, p<0.0001). Children did not have a significantly increased risk of death (RR 1.38, 95% CI 1.03 to 1.87, p=0.054). CONCLUSION These results highlight that while school holiday risk research regarding drowning has focused on the safety of children, these time periods also pose significant safety concerns to the rest of the population for both drowning deaths and other fatalities. Overall, the research highlights ongoing need for public education for all carers of children, as well as continuing to extend risk education to the broader community. Mitigation strategies, that is, advocacy for extending life-saving service and engaging with accommodation providers during school holidays are proposed.

Abstract
BACKGROUND Surfers play a critical role in coastal drowning prevention, conservatively estimated to make as many rescues as beach lifeguards. The Surfer Rescue 24/7 (SR24/7) program is a coastal safety intervention in Australia and New Zealand that teaches surfers safe rescue skills and promotes prevention activities. This multi-part, mixed-methods study aimed to evaluate the impact of the SR24/7 program. METHODS The study consisted of three parts employing quantitative and qualitative methods: a retrospective survey of course participants, in-depth interviews with course participants who had conducted rescues, and an analysis of self-reported skills confidence ratings before and after the program. RESULTS Triangulated results from the three study components indicated that after the course, participants exhibited high levels of satisfaction with their experience in the program and would encourage others to attend, were more observant and aware of safety concerns while surfing, had a better understanding of ocean conditions and hazards, learned new rescue techniques and skills, grasped important course concepts related to their own personal safety, and improved their confidence in responding to an emergency situation. Several participants had conducted rescues in real life and indicated that the course was effective in providing them with the baseline knowledge and skills to keep safe while helping others in the ocean. This study also provides new insight on the role of surfers in coastal safety, specifically that surfers are engaged in a range of prevention activities before rescue is required. CONCLUSIONS Despite persistent challenges in combating coastal drowning rates, the SR24/7 program is an effective intervention that helps save lives. Importantly, this study provides evidence that the course successfully equips surfers with techniques to act responsibly and safely. Expanding coastal safety focus and resources towards surfers, an often-overlooked demographic in beach safety strategies, could substantially enhance community-level capacity to prevent and respond to ocean emergencies.

Abstract
BACKGROUND Australia's overseas-born population continues to grow. This population is disproportionately affected by chronic, non-communicable diseases. Physical activity is the cornerstone of all chronic disease management. Engaging people from culturally and linguistically diverse (CALD) backgrounds in physical activity is an important public health objective. The purpose of this scoping review was to examine the factors that shape physical activity participation among people from CALD backgrounds in Australia. METHODS This scoping review followed Arksey and O'Malley's framework. Medline, Embase and CINAHL were searched with key words relating to 'physical activity', 'CALD' and 'Australia' in July 2021 and again in February 2022 for qualitative studies published in English since 2000. Exclusion criteria were: participants < 18 years old, studies specifically focusing on populations with health issues, pregnant or postpartum states. Methodological quality of included studies was evaluated using the Critical Appraisal Skills Programme with the purpose of informing future research. Data extracted from each study were analysed thematically and results were interpreted using Acculturation theory. RESULTS Of the 1130 studies, 17 met the inclusion criteria. Findings from each study were captured in three themes: Perceptions of physical activity; Acceptability and Appropriateness; and Access. Following migration, a decrease in physical activity, especially leisure-time activity, was reported. Common factors influencing physical activity engagement included perceptions of physical activity and wellbeing; language, financial and environmental barriers; as well as social, cultural, and religious considerations. CONCLUSION This review identified several factors which may interact and contribute to the decline in self-reported physical activity upon migration. Findings from this review may be used to inform future health promotion initiatives targeting people from CALD backgrounds. Future research may benefit from devising a shared definition of physical activity and studying different CALD communities over time.

A Scoping Review of the Relationship Between Physical Activity and Mental Health Among Immigrants in Western Countries: An Integrated Bio-Psycho-Socio-Cultural Lens. J Immigr Minor Health 2023; 25:1137-1151. [PMID: 37402074 DOI: 10.1007/s10903-023-01518-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/14/2023] [Indexed: 07/05/2023]
Abstract
Epidemiological evidence suggests that regular physical activity (PA) positively impacts individuals' mental health (MH). The PA-MH relationship may be critical among immigrants owing to psycho-social-cultural influences. This scoping review of 61 studies employed a holistic bio-psycho-socio-cultural framework to thoroughly investigate the complex relationship between PA (across life domains) and immigrants' MH in Western countries. A systematic search of five electronic databases (Medline, PubMed, Embase, PsycINFO and Anthropology Plus) was conducted to locate relevant articles. No limitations were applied to study design, age, gender, home country, MH condition or PA type. A bio-psycho-socio-cultural-informed conceptual model guided the analysis of the multi-domain PA-MH relationship. Immigrant PA-MH studies were conducted and reported most commonly in the USA (38%), Australia (18%), and Canada (11%). Overall, PA was positively related to MH. Each domain-specific PA appeared to be associated with unique MH-promoting pathways/mechanisms. Leisure-related PA may support MH by enhancing self-agency and minimizing risky behaviors, whilst travel- and domestic-related PA may promote self-accomplishment and physical engagement. Ethnic sports appeared to enhance resilience. Occupational-related PA was associated with either positive or negative MH, depending on the type of occupation. A bio-psycho-socio-cultural-informed model is required to gain an encompassing and integrated understanding of immigrants' health. The first iteration of such a model is presented here, along with an illustration of how the model may be used to deepen analysis and understanding of the multi-domain PA-MH relationship among immigrants and inform public health planners and practitioners.

Abstract
INTRODUCTION Swimming skills are an evidence-based component of drowning prevention. However, in Australia, many children miss out on learn to swim education. Voucher programmes may reduce swimming lesson cost and increase participation, especially among priority populations. The First Lap voucher programme provides two New South Wales state government-funded $100 vouchers for parents/carers of preschool children to contribute to swimming lesson costs. This evaluation aims to determine the effectiveness of the programme in meeting objectives of increasing preschool-aged children participating in learn to swim programmes and building parent/carer knowledge and awareness of the importance of preschool-aged children learning to swim. METHODS AND ANALYSIS A programme logic model was developed to explain the inputs, activities and intended outputs, and outcomes, which guided this mixed-methods evaluation design of quantitative and qualitative analysis within an impact/outcome evaluation. Baseline sociodemographic registration data will be provided by the parent/carer of each child participant and linked to swim school provider data on voucher redemption. Data will be collected on voucher use, knowledge, and attitudes to swimming lessons at registration and across two surveys. An economic evaluation will assess programme cost-effectiveness. CONCLUSION This evaluation will determine impacts on participation rates in learn to swim programmes, particularly within priority populations. It will examine whether the programme has influenced attitudes and motivations of parents and carers toward learn to swim programmes and water safety, whether the programme has impacted or enhanced the ability of the aquatics sector to deliver learn to swim programmes and assess its cost-effectiveness.

Abstract
ISSUE ADDRESSED School-based beach safety education programs are common, but best practice guidance and information on their design and development is limited. METHODS Researchers, professional ocean lifeguards and students participated in a co-design process to inform a lifeguard-delivered, school-based beach safety education program for a coastal community in New South Wales, Australia. Lifeguards and researchers (experts) provided structured feedback about the program in a survey and facilitated workshop; students (n = 26) aged 11 to 13 years participated in focus group sessions intended to garner in-depth understanding of their experiences at the beach and knowledge of, and attitudes towards, beach safety. RESULTS AND DISCUSSION The co-design process provided a novel and inclusive model for beach safety education program development, and valuable lessons for future efforts. Specifically, student focus groups identified several facets of pre-teens and younger teenagers' beach experience that prompted revision of the education program, primarily framing of program content and safety messages. Peers are a primary motivator for this age group and students' burgeoning independence emerged as an important theme. While knowledgeable about beach hazards and risks, students conveyed mixed safety attitudes and self-reported safety practices, highlighting the importance of designing programs to motivate behaviour and promote safe decision-making vs raising awareness alone. Findings illustrate the value of adopting co-design processes for all beach safety programs, school or otherwise. SO WHAT?: Beach safety programs may not be delivering information that is needed, wanted or useful. Structured consultation with the priority population must become standard practice in beach safety and drowning prevention education program development.

Abstract
Adult drowning is a complex and multifactorial public health challenge requiring community, national and global efforts to mitigate impacts. This study updates the evidence base for public health interventions that address adult fatal and non-fatal drowning. A systematic review was undertaken of the peer-reviewed literature for English-language primary studies published between 2011 and 2021describing a drowning intervention with adults. Twenty-two studies were included. Most studies (n = 16) were conducted in high-income countries. Yearly trends in drowning prevention intervention publications were analysed with 2015 (n = 6) the peak publishing year. Over half of the study designs were pre-post (n = 15). Intervention duration ranged from 4 hours to 11 years. Ten studies described either behaviour change theory or formative evaluation to inform design. Thirteen studies targeted interventions at a population level, seven at a group level and two at individual level. Studies identified a range of prevention strategies, categorised as behavioural (n = 9) (e.g., swimming lessons), socio-ecological (n = 8) (e.g., mandatory personal flotation devices) and mixed (n = 5) (e.g., awareness campaign and barriers to prevent access to water). A range of outcomes were described including changes in awareness, water safety knowledge, attitudes, water safety behaviours and skills, environmental, policy and regulation changes and drowning rates. Findings indicate a small but important increase in the evaluation and publication of effective interventions to prevent adult drowning. The complexity of the issues surrounding drowning requires multi-strategy and context -specific adult focused prevention interventions. Contemporary evidence that identifies effective interventions that contribute to prevention efforts is an essential first step in addressing the challenge.

Abstract
Multicultural communities in Australia are recognised as a priority area for drowning prevention, but no evidence-based study has addressed their knowledge of beach safety. This study used an online survey tool to identify and examine risk factors relating to swimming ability, beach visitation characteristics and behaviour, and beach safety knowledge of the Australian Southern Asian community to assist in the development of future beach safety interventions. Data was obtained through 249 online and in-person surveys of people aged > 18 years. Most respondents reported poor swimming ability (80%), often swam in in the absence of lifeguards (77%), did not understand the rip current hazard (58%), but reported that they entered the water (76%) when visiting beaches. Close to one-quarter (28%) had not heard, or didn't know the purpose, of the red and yellow beach flags, which identify lifeguard supervised areas on Australian beaches. Length of time living in Australia is an important beach safety consideration for this community, with minimal differences in terms of gender and age. Those who have lived < 10 years in Australia visit beaches more frequently and are less likely to have participated in swimming lessons, be able to swim, heard of the flags or swim between them, understand rip currents, or have participated in a beach safety program. Very few (3%) respondents received beach safety information from within their own community. The importance of beach safety education and swimming lessons within the Southern Asian community should be prioritised for new and recent migrants to Australia.

Abstract
OBJECTIVE This study aimed to describe the epidemiology and risk factors contributing to drowning among migrants in Australia. METHODS A total population retrospective epidemiological study of unintentional drowning deaths in Australia between 1 July 2009 and 30 June 2019 of people born outside Australia (migrants). Cases were extracted from the National Coronial Information System. Descriptive statistics, chi-square and relative risk were calculated. Crude drowning rates were based on country of birth and population in Australia. RESULTS There were 572 migrant deaths over the study period, 28.9% of total drowning deaths, 82.9% were male. Twenty-one per cent were aged 25-34 years and 40.8% had lived in Australia for 20+ years. Migrants at highest risk of drowning were from: South Korea (2.63/100,000 95%CI: 0.85-8.25), Taiwan (2.29/100,000 95%CI: 0.27-13.44), and Nepal (2.15/100,000 95%CI: 0.23-11.55). Migrants were more likely to drown when around rocks (p<0.001) compared with Australian-born people, who most frequently drowned in rivers (p<0.001). CONCLUSIONS Migrants are not over-represented in drowning statistics. However, unique trends were found for drowning among migrants based on country of birth and length of time in Australia. Implications for public health: Holistic drowning prevention strategies and policies are required to effectively lower drowning risk among migrant communities.
