- Description: Several important methodological issues need to be considered when designing sports injury case-control studies. Major design goals for case-control studies include the accounting for prior injury risk exposure, and optimal definitions of both cases and suitable controls are needed to ensure this. This article reviews methodological aspects of published sports injury case-control studies, particularly with regard to the selection of controls. It argues for a new approach towards selecting controls for case-control studies that draws on an interface between epidemiological and biomechanical concepts. A review was conducted to identify sport injury case-control studies published in the peer-review literature during 1985-2008. Overall, 32 articles were identified, of which the majority related to upper or lower extremity injuries. Matching considerations were used for control selection in 16 studies. Specific mention of application of biomechanical principles in the selection of appropriate controls was absent from all studies, including those purporting to evaluate the benefits of personal protective equipment to protect against impact injury. This is a problem because it could lead to biased conclusions, as cases and controls are not fully comparable in terms of similar biomechanical impact profiles relating to the injury incident, such as site of the impact on the body. The strength of the conclusions drawn from case-control studies, and the extent to which results can be generalized, is directly influenced by the definition and recruitment of cases and appropriate controls. Future studies should consider the interface between epidemiological and biomechanical concepts when choosing appropriate controls to ensure that proper adjustment of prior exposure to injury risk is made. To provide necessary guidance for the optimal selection of controls in case-control studies of interventions to prevent sports-related impact injury, this review outlines a new case-control selection strategy that reflects the importance of biomechanical considerations, which ensures that controls are selected based on the presence of the same global injury mechanism as the cases. To summarize, the general biomechanical principles that should apply to the selection of controls in future case-control studies are as follows: (i) each control must have been exposed to the same global injury mechanism as the case, (e.g. head impact, fall onto outstretched arm); and (ii) intrinsic (individual) factors (e.g. age, sex, skill level) that might modify the person's response to the relevant biomechanical loads are adjusted when either selecting the controls or are in the analysis phase. The same considerations for control selection apply to other study designs such as matched cohort studies or case-crossover studies. © 2011 Adis Data Information BV. All rights reserved.

- Description: Objective For effective sports injury prevention, information is needed about the implementation context for interventions. This study describes coaches' feedback on the implementation of an evidence-informed injury prevention programme in community junior netball using coaches' perceptions and the RE–AIM framework. Methods A lower-limb injury prevention programme (Down to Earth; D2E), for teaching safe-landing techniques, was delivered to 31 coaches from 31 junior community netball teams in a 1-h workshop. Coaches then delivered a 6-week programme at team training sessions starting in the week before the competition season commenced. 65% of coaches completed a feedback survey 17 weeks after they had delivered the programme. Results Most (88%) coaches believed that D2E improved their players' ability to perform correct landing techniques in games and that players had retained these improvements over the season. The majority (83%) indicated that an improvement in player athletic attributes was the greatest advantage of D2E, followed by a reduction in injury risk. Identified barriers to implementing D2E were running out of time and very young players finding the drills too difficult. Coaches reported that they needed more ideas for training drills that could be incorporated into their programmes and believed that their own coaching training did not adequately prepare them to implement an injury prevention programme. Conclusions Although coaches believed that D2E was effective in developing correct landing techniques, some modifications are needed to make it more suitable for younger players and coach education by accreditation courses could be improved to support the implementation of injury prevention programmes.

- Description: Objective:High-quality sport-specific information about the nature, type, cause, and frequency of injuries is needed to set injury prevention priorities. This article describes the type, nature, and mechanism of injuries in community Australian Football (community AF) players, as collected through field-based monitoring of injury in teams of players.Data Sources:Compilation of published prospectively collected injury data from 3 studies in junior community AF (1202 injuries in 1950+ players) and 3 studies in adult community AF (1765 injuries in 2265 players). This was supplemented with previously unpublished data from the most recent adult community AF injury cohort study conducted in 2007 to 2008. Injuries were ranked according to most common body regions, nature of injury, and mechanism.Main Results:In all players, lower limb injuries were the most frequent injury in community AF and were generally muscle strains, joint sprains, and superficial injuries. These injuries most commonly resulted from incidental contact with other players, or from overexertion. Upper limb injuries were less common but included fractures, strains, and sprains that were generally caused by incidental contact between players and the result of players falling to the ground.Conclusions:Lower limb injuries are common in community AF and could have an adverse impact on sustained participation in the game. Based on what is known about their mechanisms, it is likely that a high proportion of lower limb injuries could be prevented and they should therefore be a priority for injury prevention in community AF.

- Description: Objective: Scientific knowledge about symptoms of common mental disorders in elite sports is scarce. Consequently, the objectives of the study were to (i) establish the 12-month incidence of symptoms of common mental disorders (CMD; distress, anxiety/depression, sleep disturbance, adverse alcohol use, eating disorders) among Dutch elite athletes and (ii) explore their potential association with several stressors (being injured, recent life events, career dissatisfaction).Methods: A prospective cohort study with a 12-month follow-up period was conducted. The study used validated questionnaires to assess symptoms of common mental disorders (thus not clinically diagnosed) as well as several stressors; an electronic questionnaire was set up and repeatedly distributed.Results: A total of 203 elite athletes gave their written informed consent to participate in the study, from which 143 completed the 12-month follow-up period (follow-up rate of 70%). Incidence of symptoms of CMD ranged from 6% for adverse alcohol use to 57% for symptoms of anxiety/depression. Over the follow-up period, around 17% of the participants reported two simultaneous symptoms of CMD, and around 19% reported three simultaneous symptoms of CMD. Inferences between some stressors and symptoms of CMD were found but none of the associations were statistically significant.Conclusions: Substantial 12-month incidence rates of symptoms of CMD (self-reported and not clinically diagnosed) were found among Dutch elite athletes (especially for anxiety/depression), appearing similar to the ones found among athletes from other sports disciplines and the Dutch general population. Also, inferences between some stressors and symptoms of CMD were found but none of the associations were statistically significant. Supportive and preventive measures directed towards symptoms of CMD should be developed to improve awareness and psychological resilience of athletes, which would likely improve their performance and quality-of-life.

Theoretical perspectives on using epidemiology and systems thinking to better understand the aetiology and prevention of distance running-related injury

- Description: On a global scale, the sporting activity of distance running has increased in popularity. This is likely attributable to a growing societal concern for the documented rise in several lifestyle-related chronic diseases. As a form of exercise, running provides significant beneficial effects on a range of biomedical health indices, and is the preferred physical activity of choice for many people given its high accessibility and relatively low financial cost. Notwithstanding the many health-related benefits associated with running, the risk of sustaining a distance running-related injury (RRI) can be high. Therefore, from an injury prevention perspective, understanding why runners sustain RRI is of primary scientific importance. Over the last fifty years, the science behind RRI causation and prevention has attracted considerable interest amongst sports injury prevention researchers. During that time, there has been a concerted scholarly effort to understand the aetiology of RRI from an epidemiological and clinical research-based standpoint. Traditional scientific approaches have attempted to identify the effect of discrete trainingrelated, behavioural, and/or biomechanical exposures on the risk of developing either general or specific RRI. Despite what is now a considerable body of work, several descriptive and systematic reviews have found a history of previous injury to be the only definitive risk factor for subsequent RRI development. Alongside the continuing application of traditional scientific approaches, this PhD thesis promotes the use of a complementary ‘systems thinking’ theoretical perspective for better understanding the development and prevention of RRI. There are several contained chapters, the first of which is a systematic review of the RRI aetiological literature. After examining in closer detail the causal mechanism underpinning RRI development, a series of papers urge injury prevention scientists to consider drawing on alternative philosophical perspectives when planning and designing research. In building on the preceding arguments, the final chapters involve the construction of a systems ergonomics control structure model of the Australian distance running system, including the way RRI is managed and controlled.

- Description: Objectives: Previous sports injury is a known risk factor for subsequent osteoarthritis (OA), but population-based rates of sports injury are unknown. The aims of this study were to: (1) describe the trends in the population incidence and burden of all hospital-treated sports injury in Victoria, Australia in adults aged 15+ years; (2) determine the incidence of lower limb and knee injuries; and (3) quantify their population health burden as average direct hospital costs per injury and lengths of stay. Methods: Health sector data relating to adults aged 15+ years, for 2004-2010 inclusive, was extracted from the Victorian Admitted Episodes Dataset (VAED) and Victorian Emergency Minimum Dataset (VEMD). Data relating to sports injuries were identified using activity codes in each dataset Trends in injury frequency and rates were determined, and economic burden was calculated. Results: The overall annual rate of hospital treated sports injuries increased by 24% (P = 0.001), and lower limb injuries by 26% (P = 0.001) over the 7 years. The associated accumulated economic burden was $265 million for all sports injuries and $110 million for lower limb injuries over the 7-years. Conclusions: The findings of this study show a significant increase in sports injuries in the state of Victoria, Australia over a 7-year period. As previous sports injury is a risk factor for the development of OA, the future incidence of OA will escalate, placing an even greater burden on health care systems. Population-wide preventative strategies that reduce the risk of sports injury are urgently required in order to reduce the future burden of OA. © 2015 Osteoarthritis Research Society International.

- Description: Arsenic in dust and aerosol generated by mining, mineral processing and metallurgical extraction industries, is a serious threat to human populations throughout the world. Major sources of contamination include smelting operations, coal combustion, hard rock mining, as well as their associated waste products, including fly ash, mine wastes and tailings. The number of uncontained arsenic-rich mine waste sites throughout the world is of growing concern, as is the number of people at risk of exposure. Inhalation exposures to arsenic-bearing dusts and aerosol, in both occupational and environmental settings, have been definitively linked to increased systemic uptake, as well as carcinogenic and non-carcinogenic health outcomes. It is therefore becoming increasingly important to identify human populations and sensitive sub-populations at risk of exposure, and to better understand the modes of action for pulmonary arsenic toxicity and carcinogenesis. In this paper we explore the contribution of smelting, coal combustion, hard rock mining and their associated waste products to atmospheric arsenic. We also report on the current understanding of the health effects of inhaled arsenic, citing results from various toxicological, biomedical and epidemiological studies. This review is particularly aimed at those researchers engaged in the distinct, but complementary areas of arsenic research within the multidisciplinary field of medical geology. © 2014 by the authors; licensee MDPI, Basel, Switzerland.

- Description: A lack of available injury data on community sports participants has hampered the development of informed preventive strategies for the broad-base of sports participation. In community sports settings, sports trainers or first-aiders are well-placed to carry out injury surveillance, but few studies have evaluated their ability to do so. The aim of this study was to investigate the reporting rate and completeness of sports trainers' injury records and agreement between sports trainers' and players' reports of injury in community Australian football. Throughout the football season, one sports trainer from each of four clubs recorded players' injuries. To validate these data, we collected self-reported injury data from players via short message service (SMS). In total, 210 discrete injuries were recorded for 139 players, 21% by sports trainers only, 59% by players via SMS only, and 21% by both. Completeness of injury records ranged from 95% to 100%. Agreement between sports trainers and players ranged from K=0.32 (95% confidence interval: 0.27, 0.37) for date of return to football to K=1.00 for activity when injured. Injury data collected by sports trainers may be of adequate quality for providing an understanding of the profile of injuries. However, data are likely to underestimate injury rates and should be interpreted with caution. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

- Description: A lack of available injury data on community sports participants has hampered the development of informed preventive strategies for the broad-base of sports participation. In community sports settings, sports trainers or first-aiders are well-placed to carry out injury surveillance, but few studies have evaluated their ability to do so. The aim of this study was to investigate the reporting rate and completeness of sports trainers' injury records and agreement between sports trainers' and players' reports of injury in community Australian football. Throughout the football season, one sports trainer from each of four clubs recorded players' injuries. To validate these data, we collected self-reported injury data from players via short message service (SMS). In total, 210 discrete injuries were recorded for 139 players, 21% by sports trainers only, 59% by players via SMS only, and 21% by both. Completeness of injury records ranged from 95% to 100%. Agreement between sports trainers and players ranged from K=0.32 (95% confidence interval: 0.27, 0.37) for date of return to football to K=1.00 for activity when injured. Injury data collected by sports trainers may be of adequate quality for providing an understanding of the profile of injuries.

- Description: Background Fifteen percent of the world's population live with disability, and many of these individuals choose to play sport. There are barriers to sport participation for athletes with disability and sports injury can greatly impact on daily life, which makes sports injury prevention additionally important. Objective The purpose of this review is to systematically review the definitions, methodologies and injury rates in disability sport, which should assist future identification of risk factors and development of injury prevention strategies. A secondary aim is to highlight the most pressing issues for improvement of the quality of injury epidemiology research for disability sport. Methods A search of NICE, AMED, British Nursing Index, CINAHL, EMBASE and Medline was conducted to identify all publications up to 16 June 2015. Of 489 potentially relevant articles and reference searching, a total of 15 studies were included. Wide study sample heterogeneity prevented data pooling and meta-analysis. Results Results demonstrated an evolving field of epidemiology, but with wide differences in sports injury definition and with studies focused on short competitions. Background data were generally sparse; there was minimal exposure analysis, and no analysis of injury severity, all of which made comparison of injury risk and injury severity difficult. Conclusion There is an urgent need for consensus on sports injury definition and methodology in disability sports. The quality of studies is variable, with inconsistent sports injury definitions, methodologies and injury rates, which prevents comparison, conclusions and development of injury prevention strategies. The authors highlight the most pressing issues for improvement of the quality in injury epidemiology research for disability sport.

Epidemiology, injury and illness prevention in Olympic combat sports
- Authors: Bromley, Sally

- Description: Background: Olympic combat sports are commonly considered dangerous, however injury rates for these sports are not well understood. Isolated studies in combat sports have investigated injury, however these are mainly during competition, and therefore are unlikely to include significant or persistent injury which prevents athletes competing and participating in data collection. This thesis was undertaken as a series of linked studies, to provide further detail into the types, mechanisms and aetiology of injuries in combat sports. Methods: Study 1 was a systematic review that utilised the PRISMA guidelines to investigate the current evidence. Study 2 was a repeated measures study to examine the reliability of training load measures. Study 3 employed a longitudinal study design to assess the feasibility of injury, illness and training load monitoring. Finally, Study 4 was a cross-sectional cohort study that gathered perspectives of combat sport coaches and managers before and after an injury and illness prevention workshop. Results: Study 1 found one high-quality epidemiological study with low risk of bias in Judo. Variation in injury and illness definitions prevented cross-sport comparisons, however the injury incidence was comparable to other sports. In Study 2, rating of perceived exertion (RPE) was shown to have good stability across sessions (ICC=0.84), and no significant differences were found between coach (observed) and athlete (experienced) RPE (ordered logistic regression coefficient = 0.47 [1.51–0.57 95%CI]). Study 3 found that athlete engagement with the monitoring system was low, with only 13% of athletes entering data across a 12-week period. Irrespective of low engagement, 62 injuries and illnesses were recorded. In Study 4, combat sport coaches and managers were found to be generally well informed of the risk and seriousness of injury and illness, however, illness risk perceptions changed after the workshop (p=0.048). Discussion and Conclusion: Currently, cross-sport comparisons are not possible due to varying data methodology and study quality. Based upon the results presented in this thesis, RPE can be used as a tool to quantify training load in the sport of judo. Longitudinal surveillance of training load, injury and illness in combat sport is not currently feasible within the Australian system, due to low uptake and engagement. However, the collection of data on a large number of injuries and illnesses indicates that athletes are experiencing multiple, repeated health problems. Coaches and managers are well informed about injury and illness risk and seriousness, indicating that injury and illness prevention education alone may not translate to a decrease in injury and illness incidence in combat sport.

- Description: Background: There is no universally accepted age cut-off for defining young strokes. Aims: We aimed to determine, based on the profile of young stroke patients in our regional centre, an appropriate age cut-off for young strokes. Methods: A retrospective analysis of all ischaemic stroke patients admitted to our centre from 2015 to 2017. We identified 391 ischaemic stroke patients; 30 patients between the ages of ≤50, 40 between 51–60 inclusive and 321 ≥ 61 years of age. We collected data on demographic profiles, risk factors and stroke classification using the Trial of Org 10 172 in Acute Stroke Treatment criteria. Results: We found significant differences between the ≤50 and ≥61 age groups for most of the risk factors and similarities between the 51–60 inclusive and ≥ 61 age groups. At least one of the six risk factors assessed in the study was present in 86.7% of the youngest group, 97.5% of the intermediate age group and 97.2% in the oldest group. In terms of the mechanisms of stroke, the youngest and oldest age groups in our study differed in the prevalence of cryptogenic, cardioembolic and other causes of stroke. The middle and older age groups had similar mechanisms of stroke. Conclusions: The prevalence of vascular risk factors and mechanisms of stroke likewise differed significantly across age groups. This study suggests that 50 years is an appropriate age cut-off for defining young strokes and reinforces the importance of primary prevention in all age groups. © 2019 Royal Australasian College of Physicians

- Description: Background: This study aims to (i) estimate the prevalence of blood-injection-injury phobia (BIIP) diagnosed as present at any time during the life prior to the interview, with or without another Specific Phobia diagnosed as present during the 12 months prior to the interview, (ii) characterize types and frequencies of co-occurring fears, (iii) evaluate the association with chronic medical conditions and lifetime psychiatric comorbidity, and (iv) explore medical service use associations in a nationally representative sample of older adults. Methods: A sample of 8,205 older adults, aged 65 years or older, was derived from Wave 1 of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC). Results: The weighted lifetime prevalence of BIIP with and without 12-month Specific Phobia was 0.6% (95% CI: 0.4-0.8) and 4.2% (95% CI: 3.7-4.8), respectively, and these two groups ranked similarly in terms of sociodemographic, health, and psychiatric characteristics. BIIP most frequently co-occurred with other lifetime fears, and was positively associated with hypertension and lifetime history of anxiety and personality disorders after controlling for sociodemographic and psychiatric confounders. Conclusions: Our findings suggest that lifetime BIIP may bear mental and physical health significance in older adults. © 2016 International Psychogeriatric Association.

Data from Waves 1 (N = 43,093; 2001–2002) and 2 (N = 34,653; 2004–2005) of the National Epidemiological Survey on Alcohol and Related Conditions (NESARC) were used to assess whether adverse events at baseline are associated with increased risk of anxiety disorder onset over three years of follow up. Sixty-six percent (SE: 1.0) of respondents with an anxiety disorder in the intervening period between Waves 1 and 2 had experienced an adverse life event in the year prior to the Wave 1 interview. In logistic regression models adjusted for sociodemographic and psychiatric characteristics, adverse life events at baseline were associated with anxiety disorder onset within the three-year follow up period. The pattern of association between adverse events and anxiety disorder onset was similar across sub-types, and injury, illness or death of family or close friends consistently had the strongest association with anxiety disorder onset. These findings suggest that adverse life events play a role in the onset of anxiety disorders.

- Description: Robust epidemiological studies identifying determinants of negative health outcomes require significant research effort. Expert judgement is proposed as an efficient alternative or preliminary research design for risk factor identification associated with unintentional injury. This proposition was tested in a multi-factorial balanced experimental design using specialist judges (N = 18), lifeguards and surfers, to assess the risk contribution to drowning for swimming ability, surf bathing experience, and wave height. All factors provided unique contributions to drowning risk (p < .001). An interaction (p = .02) indicated that occasional surf bathers face a proportionally increased risk of drowning at increased wave heights relative to experienced surf bathers. Although findings were limited by strict criteria, and no gold standard comparison data were available, the study provides new evidence on causal risk factors for a drowning scenario. Countermeasures based on these factors are proposed. Further application of the method may assist in developing new interventions to reduce unintentional injury. © 2019 Morgan, Ozanne-Smith.

- Description: Objective This study assessed the changes in prevalence and associated factors of tobacco smoking among Bangladeshi adults over time. Design Nationally representative cross-sectional surveys. Setting Two most recent Global Adults Tobacco Survey (GATS) data from Bangladesh, carried out in 2009 and 2017. Participants Adult population aged 15 and above (n=9629 in 2009; n=12 783 in 2017). Outcome measures Current use of tobacco smoke, including cigarettes, bidi, hukkah, cigars or pipes, which was dichotomised ( yes'/ no'). Methods We analysed data from two recent rounds of GATS (2009 and 2017). Multivariate logistic regression analysis was used. Results The overall prevalence of tobacco smoking among Bangladeshi adults was noted (23.00%, 95% CI 22.98 to 23.00 in 2009; 16.44%, 95% CI 16.43 to 16.45 in 2017). Being male (adjusted OR (AOR)=59.72, CI 40.56 to 87.93 for 2009; AOR=71.17, CI 41.08 to 123.32 for 2017), age between 25 and 64 years (all AORs >2 and p<0.05), smoking permissible at home (AOR=7.08, CI 5.88 to 8.52 for 2009; AOR=5.90, CI 5.34 to 6.95 for 2017), and watching tobacco smoking product use in movie/drama scenes (AOR=1.26, CI 1.11 to 1.44 for 2009; AOR=1.34, CI 1.17 to 1.54 for 2017) were found to be significantly associated with increased tobacco smoking among adults both in 2009 and in 2017. However, being offered free tobacco sample products (AOR=0.66, CI 0.57 to 0.77 for 2009; AOR=0.87, CI 0.76 to 0.99 for 2017) and having primary, secondary or higher education (all AORs <1 and p<0.05) as well as being a student (AOR=0.16, CI 0.09 to 0.29 for 2009; AOR=0.32, CI 0.19 to 0.53) were associated with lower odds of tobacco smoking in both surveys. Conclusions Although the prevalence of tobacco smoking has declined over the period, it is still high among those who were relatively older, men, less educated and exposed to a movie/drama where tobacco smoking is promoted. Therefore, appropriate interventions are required to stop tobacco smoking among the Bangladeshi population. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Muhammad Aziz Rahman” is provided in this record**.

Conclusions Although the prevalence of tobacco smoking has declined over the period, it is still high among those who were relatively older, men, less educated and exposed to a movie/drama where tobacco smoking is promoted. Therefore, appropriate interventions are required to stop tobacco smoking among the Bangladeshi population. **Please note that there are multiple authors for this article therefore only the name of the first 5 including Federation University Australia affiliate “Muhammad Aziz Rahman” is provided in this record**.

- Description: This review aimed to examine the extent of Bangladesh's COVID-19 preparedness and control measures up to 20 January 2021, and to draw some lessons for informing the current and future pandemic responses in Bangladesh in light of Vietnam's responses, which had successfully controlled the pandemic. We performed a content analysis of data to identify similarities and critical discrepancies in epidemiological features and COVID-19 responses between the two countries. Findings indicated that Vietnam reported lower COVID-19 incidence (15 cases per million) and death rate (0.4 cases per million) than Bangladesh, with 3,129 cases per million and a death rate of 46 cases per million. Vietnam reported only 35 deaths, with 22 older individuals (>60 years) compared with 7,950 deaths in Bangladesh, with the highest death rate in older people (45%). An integrated approach combined with widespread contact tracing, better health investment, vaccine development, and strong political commitment enabled Vietnam to control the disease and mitigate its impacts. In contrast, Bangladesh seemed to adopt inadequate and untimely measures in the same domains, potentially contributing to relatively high COVID-19 infections and death rates. To control COVID-19 or inform responses to future pandemics, Bangladesh and similar countries can learn eight lessons from Vietnam. Such transferable responses could prepare health systems and populations for an appropriate global response to the next potential pandemic.
