Orofacial injuries in child family homicide: a population study.

Child family violence homicide (FVH) is a significant public health problem in Australia and globally. Population-wide studies of orofacial injuries in child FVH are uncommon despite their recognized importance. This whole population descriptive study of orofacial injuries in child FVH in Victoria, Australia aims to implement a novel methodological approach to provide an overview of child FVH and describe frequency and patterns of abusive orofacial injuries. Closed cases of child FVH aged 0-17 years, January 2000-December 2018, were identified from screening all Victorian assault deaths for eligible offender relationships. Significant associations of clinical/demographic characteristics were explored using two-step clustering and the Spearman correlation coefficient. Of 895 closed homicide cases, 358 were FV-related. Of the 53 child FVH, 40 were eligible for injury analysis with 36 of these cases (90%) having orofacial injuries. Among these 36 cases, 72% were aged 0-4 years, males predominated (64%) and the injury mechanism was blunt force for 56%. The discrete orofacial injury frequency was associated with the non-orofacial injury frequency (rho: 0.362, 2-tailed p < 0.03). A three-cluster statistical solution was identified, each represented by an injury mechanism. The largest cluster identified a pattern of blunt force trauma in 0-4 years with drug presence, high average non-orofacial injury numbers and parent-offenders. A novel methodological approach was implemented to comprehensively describe the frequency, nature, patterns and risk indicators of orofacial injuries in child FVH. It explored associations between a wide range of clinical and demographic characteristics, which might have otherwise been missed in summary description. These methods will potentially underpin future comparative studies of intentional-unintentional child injuries and fatal-nonfatal child abuse. The study narrows a significant research gap regarding patterns of inflicted injuries, and demographic and clinical indicators in child FVH potentially informing future systematic classification processes, risk assessment tools and pathways to FV intervention.

Drowning mortality in children aged 0-14 years in Victoria, Australia: detailed epidemiological study 2001-2016.

BACKGROUND: Major reductions in child drowning mortality rates have been observed historically in Victoria, Australia, for the period 1863-2000. Despite this trend, drowning remains the leading cause of unintentional child death in Victoria. This study investigates the residual fatal drowning problem in the Victorian child population (0-14 years) for the period 2001-2016. AIMS: Describe the epidemiology of child drowning deaths in the Victorian population in 2001-2016; investigate risk factors and direct antecedents to these deaths. METHODS: Population-based retrospective case data were extracted from the National Coronial Information System for 16 years (January 2001-December 2016), and case-by-case analysis was conducted. Associated factors were determined using univariate and Poisson analyses. RESULTS: 88 of 97 cases had information available for analysis, pools were the most frequent location (30%); 70% of all cases occurred between 08:00 and 17:00; most victims were not deliberately in the body of the water (73%), for example, the pool. Supervision lapses included carers leaving the room when the child was in the bath (16/18), siblings left to supervise the child in private pools (7/23), inadequate pool fences (8/23) or faulty/open gates (4/23), or neighbours' pool spa (4/23). Delays in finding the child occurred when searches occurred elsewhere, before the body of water (21/88) and when carers were asleep (5/88). Fourteen of the 88 children had an intellectual disability or predisposing medical condition. The grouped Poisson analysis demonstrated that age 0-4 years, male gender and rural place of residence were significant. A downward trend in drowning rate continued in this period. DISCUSSION AND CONCLUSIONS: A case-by-case analysis of a drowned population of children identified details of risk factors and antecedents not previously described. Missing data on antecedents were common, likely resulting in undercounting. Further enhancements to systematic data collection are needed. The results support a systems approach to drowning prevention.

Methods in population study of orofacial injuries in Victorian family violence homicides.

This study standardized the methods used in the determination of orofacial injuries in Victorian family violence homicides and informed potential control selection for an analytic study. Dental service contacts with family violence victims may be intervention avenues due to the presence of abusive injuries in the orofacial region. All Victorian family homicides from January 2000-September 2018 were identified by determining the kinship/relationship and grouped by age. A 20% random sample of adult cases, aged 18-64 years was selected. The median number of orofacial injuries in categories of injury mechanisms/age/gender and the nature of abusive orofacial injuries was reported for the sample. Of 357 closed cases of family homicide, 261 were adults aged 18-64 years. Offender information and injury mechanism data was available for all closed cases, enabling case selection. Of a random sample of 50 adults, 8 cases were excluded. After 2006, CT scans and photos were present in 20 (91%) and 19 (86.4%) of 22 cases, respectively. The nature and median number of orofacial injuries showed correlation to the reported injury mechanism. Strengths and limitations of the used methods were assessed. Not all cases were compatible for assessment of orofacial injuries, thus serving as an additional criterion for exclusion in our methodology. Further detailed study of the whole population of adults should be limited to the period 2006-2018 where the data is more complete. The mechanism of injury may influence control selection for analytic studies. We present preliminary evidence of the frequent occurrence of orofacial injuries in family violence homicides.

Mandatory reporting of child physical abuse and dental neglect by Australian dentists.

Child protection measures are organized into three major themes: laws; service programs; and status of outcomes of these interventions. Contextually, mandatory reporting of child abuse and neglect is governed by a complex system of State legislation across Australia. The purpose of this review was to investigate the evidence base for the legislative obligations of Australian dentists as mandatory reporters; the functionality of dental practice in the determination of orofacial signs of abuse and neglect; and, relevant knowledge and practice demonstrated by the Australian dental work force. Our research question explores the role of Australian dentists in intervention of child physical abuse and dental neglect. Information was sourced from literature and web-based reviews. Peer reviewed articles included reviews and empirical studies. Official websites/databases were accessed for relevant legislation. The study found that child protection laws lack an evidence base for including/excluding dentists as reporters. Child abuse and neglect is associated with strong orofacial signs, thus imparting a key advantage to utilizing dentists as potential notifiers. An action response to child abuse is not seen in the Australian dental service. This review identifies gaps in the dental literature concerning mandatory reporting, calls for optimization of the related evidence base, and uniform Australian child abuse reporting requirements.

A social change perspective on injury prevention in China.

INTRODUCTION: China has undergone massive social change over the past four decades. Since national estimates became available in 1987, the overall fatal injury rate has decreased. This paper investigates targeted interventions and sociodemographic factors that may have contributed to fatal injury rate changes particularly for road traffic fatality (RTF), suicide and drowning. AIMS: (1) To review the recent epidemiology of injury in China.(2)To investigate factors influencing trends in overall and specific cause injury mortality rates. METHODS: Published injury mortality statistics and related literature were reviewed. Factors potentially influencing trends were investigated in the context of rapid development based on literature reviews of targeted interventions, macrolevel and microlevel contextual factors and changes specific to RTF, suicide and drowning. RESULTS: Overall estimated national injury mortality rates in China decreased between 1987 and 2015, despite a rapid rise in RTF. Suicide and drowning rates decreased significantly and falls displaced drowning among the leading causes. The higher female to male suicide ratio reversed. Differences were observed in frequencies and proportions of deaths by major cause by age group and over time. DISCUSSION: Economic and structural development and related social change in this period include: urbanisation, changes in demographics, life choices (eg, internal migration), education, poverty alleviation, health insurance and relevant regulations/legislation. These factors potentially explain much of the change in fatal injury rates in China. Data limitations persist. Increased investment in data and research would provide realistic opportunities for accelerated progress in implementing effective targeted interventions to further reduce China's injury burden.

Drowning deaths between 1861 and 2000 in Victoria, Australia.

OBJECTIVE: To identify the long-term patterns of drowning mortality in the state of Victoria, Australia, and to describe the historical context in which the decrease occurred. METHODS: We obtained data on drowning deaths and population statistics from the Australian Bureau of Statistics and its predecessors for the period 1861 to 2000. From these data, we calculated drowning death rates per 100 000 population per year, by gender and age. We reviewed primary and secondary historical resources, such as government and newspaper archives, books and the Internet, to identify changes or events in the state that may have affected drowning mortality. FINDINGS: From 1861 to 2000, at least 18 070 people drowned in Victoria. Male drowning rates were higher than those for females in all years and for all ages. Both sexes experienced the highest drowning rate in 1863 (79.5 male deaths per 100 000 population and 18.8 female death per 100 000 population). The lowest drowning rate was documented in 2000 (1.4 male deaths per 100 000 population and 0.3 female deaths per 100 000 population). The reduction patterns of drowning mortality occurred within a historical context of factors that directly affected drowning mortality, such as the improvement in people's water safety skills, or those that incidentally affected drowning mortality, like infrastructure development. CONCLUSION: We identified patterns of reduction in drowning mortality, both in males and females and across age groups. These patterns could be linked to events and factors that happened in Victoria during this period. These findings may have relevance to current developing communities.

Epidemiological profile of hospitalised injuries among electric bicycle riders admitted to a rural hospital in Suzhou: a cross-sectional study.

Police reports indicate an increasing burden of electric bike (E-bike) casualties in China; however, hospitalised injury data have not been reported. The aim of the present work was to describe hospitalised injury patterns for E-bikers involved in road crashes and explore injury risk disparities among them. For the period October 2010 to April 2011, this cross-sectional study retrospectively collected information for hospitalised E-bikers involved in road crashes from hospital records, in Suzhou China, using the International Classification of Diseases, 10th revision (ICD-10) injury diagnosis codes. Injury nature and body region were further categorised using ICD-10 codes. Multivariate logistic regression was used to assess the risk of specific injury types. We found that hospitalised E-biker injuries (n=323) accounted for 57.2% of road traffic hospitalisations over the 6-month study period. The average age, length of stay and hospitalisation cost were 43.8 years, 10.0 days and ¥8229 (US$1286), respectively. Fractures and head injuries were common. The odds of traumatic brain injuries were significantly elevated for night-time E-bike crashes and incidents other than colliding with motor vehicles. These findings confirm E-bike injuries as an important population health problem and identify elevated injury odds in different E-biker groups. Future injury prevention initiatives should include encouraging helmet use among E-bikers.

Fatal road traffic injuries in Ibadan, using the mortuary as a data source.

BACKGROUND: Road Traffic Injury (RTI) in Africa represents 14% of global RTI deaths. Lack of timely, reliable data undermines road safety interventions. Available fatality data are aggregated, limited in detail or scarce in surveys. This is the first fatal RTI surveillance study in Nigeria. OBJECTIVE: To pilot a systematic mortuary-based data collection in Ibadan, determine the nature and circumstances of fatal RTI and assess data quality against existing data sources. METHODS: Using a draft data collection system developed jointly by WHO and Monash University, the detailed information was prospectively collected on RTI University College Hospital mortuary admissions in Ibadan September 2010 to February 2011. Demographics, road user type, counterpart vehicle, intent, manner and medical cause of death were recorded. RESULTS: Mortuary admissions included 80 fatal RTI cases: 81.3% males. By road user category, 28 (35.0%) were pedestrians; 28 (35.0%) motorised 2-wheeler users; 18.8% car occupants; and 11.3% bus occupants. In 70% of cases, medical cause of death was head injury, including 25 of 28 motorised 2-wheeler users (89.3%). Estimates from this study indicate apparent increased mortuary capture of fatal RTI compared with police data. CONCLUSIONS: This study demonstrates the feasibility of collecting detailed, timely RTI fatality data through mortuary-based surveillance in Ibadan. While not all RTI deaths are reported to any authority in Ibadan, this large case series complements existing data sources and suggests that pedestrians and motorised 2-wheeler users die most often in road traffic crashes. Frequent head injuries among motorised 2-wheeler users strongly support the need for helmet wearing interventions.

Interpretation of postmortem forensic toxicology results for injury prevention research.

Forensic toxicological data provides valuable insight into the potential contribution of alcohol and drugs to external-cause deaths. There is a paucity of material that guides injury researchers on the principles that need to be considered when examining the presence and contribution of alcohol and drugs to these deaths. This paper aims to describe and discuss strengths and limitations of postmortem forensic toxicology sample selection, variations in analytical capabilities and data interpretation for injury prevention research. Issues to be considered by injury researchers include: the circumstances surrounding death (including the medical and drug use history of the deceased person); time and relevant historical factors; postmortem changes (including redistribution and instability); laboratory practices; specimens used; drug concentration; and attribution of contribution to death. This paper describes the range of considerations for testing and interpreting postmortem forensic toxicology, particularly when determining impairment or toxicity as possible causal factors in injury deaths. By describing these considerations, this paper has application to decisions about study design and case inclusion in injury prevention research, and to the interpretation of research findings.

Surf lifeguard rescues.

OBJECTIVE: This study assessed the utility of lifeguard rescue data for providing information on person and situation factors to inform surf bather drowning prevention research. METHODS: The dataset comprised 872 beach-days (daily lifeguard reports) obtained from 26 beaches over a 95-day period in Victoria, Australia. RESULTS: The rescue rate was 128 per 100,000 in-water bathers. One or more rescues were required on 125 beach-days (14%). Rescue on a beach-day was more likely for offshore wind conditions, relatively high daily air temperatures, and high bather numbers (P < .05). Compared to female bathers, males were more frequently rescued (65%) and more likely (P < .05) to be from a younger age group (30 years or less), although being older was associated with a relatively poorer condition on rescue. CONCLUSIONS: Although rescues are proportional to water exposure, frequencies are also influenced by situation and person factors. Bathers at relatively high risk of rescue are hypothesized to be overrepresented in amenable sea and weather conditions, and poor patient condition on rescue may be associated with exposure to a preexisting health condition.

Work-related musculoskeletal injury and suicide: opportunities for intervention and therapeutic jurisprudence.

This article presents evidence for the existence of a common trajectory from work-related musculoskeletal injury to suicide. Specifically, it is argued that the pathway from injury to suicide is typically mediated by three critical events: unsuccessful return to work; the development of chronic pain or disability; and suicidal ideation in the context of chronic pain. The moderating influence of systemic factors is also examined, along with opportunities for intervention at the individual and systemic levels, the latter arising from a therapeutic jurisprudence perspective.

Application of a public health framework to examine the characteristics of coroners' recommendations for injury prevention.

OBJECTIVES: Exploring the characteristics of recommendations generated from medicolegal death investigations is an important step towards improving their contribution to injury prevention. This study aimed to: (1) quantify coroners' recommendations; and (2) examine the nature of these recommendations according to public health principles of injury causation and prevention. METHODS: Deaths where coroners' recommendations were and were not made in the State of Victoria, Australia during the period 1 July 2000 to 30 June 2005 were compared by sex, age group and underlying cause of death. The nature of recommendations made was examined retrospectively using a derived model based on principles of injury causation and prevention, comprising seven elements: (1) priority population; (2) risk/contributing factors; (3) countermeasure; (4) level of intervention; (5) strategy for implementation; (6) organisation; (7) time frame for implementation. RESULTS: Coroners' recommendations were relatively rare, made in only ∼6% of external-cause deaths. When coroners did make recommendations, they were statistically significantly more likely for persons aged 0-14 years and deaths resulting from transport crashes, complications of medical and surgical care, drowning and inanimate mechanical forces. Of the coroners' recommendations, ∼70% included at least four of the model's seven elements. The elements 'countermeasure' and 'level of intervention' were most commonly specified by coroners (∼95%) in their recommendations. CONCLUSIONS: This study shows that highly evolved medicolegal death investigation systems may not draw systematically from the scientific research evidence base to inform the formulation of coroners' public health and safety recommendations. To maximise its contribution to fatal injury prevention, the medicolegal death investigation may benefit from incorporation of a public health perspective.

Work-related non-crash heavy vehicle driver fatalities in Australia, 2000-9.

The objective of this study was to describe the nature and mechanisms of a case series of Australian work-related non-crash heavy vehicle driver fatalities. The study used existing population-based mortality data on non-crash work-related heavy vehicle (gross vehicle mass >4.5 t) driver fatalities reported to Australian coroners between 2000 and 2009. There were 47 fatalities with a mean age of 46.5 years. Available toxicology detected that six of 16 drivers consumed illegal drugs or alcohol. The most frequent task was attending to cargo (n=22, 47%); 31 (66%) fatalities occurred when the driver was working alone. Brake issues (n=21, 45%) were the most frequent contributing factor, and crushing the most common mechanism (n=33, 70%), particularly between the vehicle and another object (n=22, 47%). Fatalities occurred in most jurisdictions averaging 4.7 per year overall. A large number of truck drivers die performing non-driving tasks. Crushing following vehicle rolling accounts for almost 50% of fatalities. Considering this pathway may provide prevention opportunities.

Increasing deaths involving oxycodone, Victoria, Australia, 2000-09.

OBJECTIVE: In light of an emerging epidemic identified in the United States and Canada, to identify trends in fatal drug toxicity involving oxycodone and the demographic characteristics and indicators of socioeconomic disadvantage of the deceased. STUDY DESIGN: Population-based observational study in Victoria, Australia. POPULATION: Decedents whose death was reported to the Victorian Coroner between 2000 and 2009 and where oxycodone was detected. MAIN OUTCOME MEASURES: Association between supply of oxycodone and deaths. Demographic characteristics of decedents. Rate ratios of the rural or metropolitan location and socioeconomic indicators of disadvantage of the deceased. RESULTS: Supply to Victoria has increased nine-fold from 7.5 mg per capita in 2000 to 67.5 mg per capita in 2009. Detection of oxycodone in deaths reported to the Victorian Coroner has increased from 4 (0.08/100,000 population) in 2000 to 97 (1.78/100,000 population) in 2009-a 21-fold increase in deaths. Of the 320 cases described, 53.8% (172) were the result of drug toxicity. Of these, 52.3% were unintentional and 19.8% intentional self-harm; the remaining 27.9% are either still under investigation by the coroner or intent is unknown. Drug toxicity deaths were overrepresented in both rural areas and areas indexed with high levels of disadvantage. CONCLUSIONS: The substantial increase in the number of deaths involving oxycodone is strongly and significantly associated with the increase in supply. Most drug toxicity deaths involving oxycodone were unintentional. This newly identified trend in fatalities in Victoria supports concerns that a pattern of increasing deaths involving oxycodone is emerging globally.

Systematic Review of the Patterns of Orofacial Injuries in Physically Abused Children and Adolescents.

OBJECTIVE: To examine the evidence base for patterns of oro-facial injuries in physical abuse cases of children and adolescents aged 0-17 years. DATA SOURCES: Systematic searches of Ovid Medline, Ovid Embase, Cochrane Central and grey literature, dating from the oldest entry to August 2017. REVIEW METHODS: Search criteria included English language peer reviewed articles and theses on physical abuse cases affecting the age group of 0-17 years. Exclusion criteria were: Case reports and <10 case series; studies involving bite mark injuries elsewhere on the body, sexual, ritualistic or emotional abuse and neglect, exposure to domestic violence; reviews; book chapters and conference proceedings. The following data was extracted: quality and design of study, oro-facial manifestations, new/old injuries, fatalities, coexistent injuries, co-morbidities and radiologic investigations. Each study was subjected to two independent reviews and a third, if reviewers disagreed. RESULTS: The authors identified 51 articles, 26 of which satisfied the inclusion criteria. The oro-facial signs were superficial injuries of face, ears, neck, lips and oral mucosa, burns, torn fraenii and fractured teeth and jaws. A minority of studies stood out due to their well-developed design; expert opinion inclusion; new/old/occult injury investigations and facial bruising/ intraoral injuries as sentinel markers. Overall, the review demonstrated weak study quality and representativeness as well as lacunae in uniform reporting. CONCLUSIONS: The available literature does not endorse any pathognomonic signature patterns of child physical abuse to the exposed oro-facial region.

The prevalence of work-related deaths associated with alcohol and drugs in Victoria, Australia, 2001-6.

To describe the presence of alcohol, cannabis and amphetamines in work-related injury deaths in Victoria, 2001-6, an observational study of work-related deaths reported to the State Coroner's Office, Victoria, Australia was conducted. Case and postmortem forensic toxicology data were obtained from the National Coroner's Information System for work-related injury deaths with positive toxicology screens. Over 6 years there were 43 worker deaths in a total of 355 unintentional work-related injury deaths. The coroner mentioned the presence of alcohol/drugs in 22 of the 43 worker deaths with positive toxicology screens. Toxicology screens were positive for alcohol and/or drugs in 79 work-related deaths overall. Overall, alcohol was present in 26 (7%) work-related deaths and cannabis or amphetamines in 20 (6%). Incidents were mainly transport related. Alcohol and/or drugs were present in a significant portion of work-related deaths. Research is needed to determine the relative contribution of alcohol and drugs compared with other contributing factors to work-related deaths.

Cultural translation: acceptability and efficacy of a US-based injury prevention intervention in China.

BACKGROUND: Increased belt-positioning booster seat (BPB) awareness and access have led to increased use in the USA. Although transportation in Beijing is rapidly becoming 'motorised', Beijing's population has limited awareness of or access to BPBs. OBJECTIVE: To explore the efficacy and acceptability of using a US-developed BPB use promotion intervention in Beijing. DESIGN: Methods were adapted from a previously executed US-based study involving parents of 3-8-year old children. Focus groups (five groups, 71 participants) elicited behavioural antecedents to BPB use and reactions to video interventions promoting BPB use: a Chinese-produced instructional video and an English-language (dubbed into Mandarin) video that delivered concrete, theoretically driven messages through a personal story. Immediately after the focus groups, participants were provided with education and a free BPB. Participants were contacted 6 weeks later via telephone about use, knowledge and attitudes. RESULTS: Chinese parents saw safety as the most important benefit of BPB use; lack of accurate knowledge about and access to BPBs were parents' most prevalent barriers. Chinese participants described the videos as persuasive and instructional. At 6 weeks, participants remembered the messages of the English-language video, and reported BPB use increased from a baseline of 15.5% to 85.5%. CONCLUSIONS: This study shows the possibility of exporting US-designed prevention interventions dubbed into Mandarin without the need to alter their original context (in this case, an African American family in a US setting) into a Chinese context. Successful cultural translation involved ensuring that the behavioural antecedents targeted in the intervention (eg, barriers and benefits) were of relevance to the Chinese population.

Bio-psychosocial determinants of time lost from work following non life threatening acute orthopaedic trauma.

BACKGROUND: To determine factors predicting the duration of time away from work following acute orthopaedic non life threatening trauma METHODS: Prospective cohort study conducted at four hospitals in Victoria, Australia. The cohort comprised 168 patients aged 18-64 years who were working prior to the injury and sustained a range of acute unintentional orthopaedic injuries resulting in hospitalization. Baseline data was obtained by survey and medical record review. Multivariate Cox proportional hazards regression analysis was used to examine the association between potential predictors and the duration of time away from work during the six month study. The study achieved 89% follow-up. RESULTS: Of the 168 participants recruited to the study, 68% returned to work during the six month study. Multivariate Cox proportional hazards regression analysis identified that blue collar work, negative pain attitudes with respect to work, high initial pain intensity, injury severity, older age, initial need for surgery, the presence of co-morbid health conditions at study entry and an orthopaedic injury to more than one region were associated with extended duration away from work following the injury. Participants in receipt of compensation who reported high social functioning at two weeks were 2.58 times more likely to have returned to work than similar participants reporting low social functioning. When only those who had returned to work were considered, the participant reported reason for return to work " to fill the day" was a significant predictor of earlier RTW [RR 2.41 (95% C.I 1.35-4.30)] whereas "financial security" and "because they felt able to" did not achieve significance. CONCLUSIONS: Many injury-related and psycho social factors affect the duration of time away from work following orthopaedic injury. Some of these are potentially modifiable and may be amenable to intervention. Further consideration of the reasons provided by participants for returning to work may provide important opportunities for social marketing approaches designed to alleviate the financial and social burden associated with work disability.

Population study of orofacial injuries in adult family violence homicides in Victoria, Australia.

BACKGROUND: This study describes the prevalence and orofacial injury patterns associated with adult family violence (FV) homicides in Victoria, Australia. It follows a methods study for case selection of all FV homicides and injury measurement. Comprehensive analysis of orofacial injuries in FV homicides and their clinico-demographic context will inform future research on clinical FV indicators and sentinel injuries, and potentially lead to premorbid intervention in health services. METHODS: All closed cases of FV homicides aged ≥18 years, January 2006 to December 2018, were identified by screening Victorian fatal assaults, based on victim-offender relationship. Primary data such as post-mortem computed tomography scans and photographs were assessed. Socio-demographic, clinical, interpersonal and incident parameters were descriptively analysed and statistically compared across FV homicides with and without facial injuries using cluster analysis and nonparametric tests. RESULTS: Of 170 adult homicides screened for eligibility, 151 were included for final analysis. Over the 12-year period, 78.1% of all Victorian adult FV homicides had orofacial injuries. Significant cluster patterns of injury mechanism, victim-offender relationship and drug/alcohol impairment were identified in all homicides. Non-facial injuries were significantly higher in facial vs. non-facial injury homicides. Facial abrasion and incised wounds were the most common injury types. CONCLUSIONS: This is the first forensic-epidemiologic study evaluating the empirical evidence concerning orofacial injuries associated with population-wide adult Victorian FV homicides. The high level of orofacial injuries in this population during the study period may inform clinical practice and policy in FV intervention in Victoria and globally.

Self-reported water and drowning risk exposure at surf beaches.

OBJECTIVE: To document patterns of water exposure at surf beaches by gender and identify factors that predict bather confidence to return to shore if caught in a rip current. METHOD: Recreational surf beach bathers (N=406) provided self-completed data on water exposure patterns, surf activity behaviours and potential drowning risk and protective factors. RESULTS: Relative to females, males visited surf beaches more frequently, expected to spend longer in the water and in deeper water, and more often bathed after using alcohol (p<0.05). Confidence to return to shore if caught in a rip current was predicted by confidence to identify a rip current, self-rated swimming ability, gender, times visited any beach, and age in a standard linear regression model (adjusted R(2)=0.68). CONCLUSION: The study supports explanations that high male drowning rates result from more frequent exposure to water than females at high situational risk levels. IMPLICATIONS: Controlled studies are required to determine the role in drowning of overconfidence, swimming ability, surf experience, floatation devices and response to sea conditions.
