Do as I say: contradicting beliefs and attitudes towards sports concussion in Australia.

The objective of this study was to explore beliefs and attitudes of students studying exercise science in Australia towards sports concussion. A secondary objective explored differences between gender and previous experience of concussion. A total of 312 participants (m = 217; f = 95) responded to a series of statements ranging across a number of areas including personal attitudes and beliefs towards concussion: if they would risk playing with a concussion; their views on elite/professional athletes who continue to play after a concussion; and attitudes towards rehabilitation. Overall, attitudes revealed that it was not safe to play with a concussion, and it was believed that those who have had repeated concussions would be likely to suffer problems later in life. However, responses also indicated that they would risk playing with a concussion, and admired elite athletes who continued to play. When controlling for gender and previous concussions, males and those who sustained a previous concussion/s were more likely to continue playing. Conversely, females were more likely to complete rehabilitation prior to returning to sport. This study demonstrates in an Australian student cohort studying for a career in exercise and sports science, disparity between beliefs and attitudes regarding sports concussion.

Participation in modified sports programs: a longitudinal study of children's transition to club sport competition.

BACKGROUND: Many children are not physically active enough for a health benefit. One avenue of physical activity is modified sport programs, designed as an introduction to sport for young children. This longitudinal study identified trends in participation among children aged 4-12 years. Outcomes included continuation in the modified sports program, withdrawal from the program or transition to club sport competition. METHODS: De-identified data on participant membership registrations in three popular sports in the Australian state of Victoria were obtained from each sport's state governing body over a 4-year period (2009-2012 for Sport A and 2010-2013 for Sports B and C). From the membership registrations, those who were enrolled in a modified sports program in the first year were tracked over the subsequent three years and classified as one of: transition (member transitioned from a modified sport program to a club competition); continue (member continued participation in a modified sport program; or withdraw (member discontinued a modified program and did not transition to club competition). RESULTS: Many modified sports participants were very young, especially males aged 4-6 years. More children withdrew from their modified sport program rather than transitioning. There were age differences between when boys and girls started, withdrew and transitioned from the modified sports programs. CONCLUSIONS: If we can retain children in sport it is likely to be beneficial for their health. This study highlights considerations for the development and implementation of sport policies and programming to ensure lifelong participation is encouraged for both males and females.

A systematic review of the psychological and social benefits of participation in sport for adults: informing development of a conceptual model of health through sport.

BACKGROUND: The definition of health incorporates the physical, social and mental domains, however the Physical Activity (PA) guidelines do not address social health. Furthermore, there is insufficient evidence about the levels or types of PA associated specifically with psychological health. This paper first presents the results of a systematic review of the psychological and social health benefits of participation in sport by adults. Secondly, the information arising from the systematic review has been used to develop a conceptual model of Health through Sport. METHODS: A systematic review of 14 electronic databases was conducted in June 2012, and studies published since 1990 were considered for inclusion. Studies that addressed mental and/or social health benefits from participation in sport were included. RESULTS: A total of 3668 publications were initially identified, of which 11 met the selection criteria. There were many different psychological and social health benefits reported, with the most commonly being wellbeing and reduced distress and stress. Sport may be associated with improved psychosocial health in addition to improvements attributable to participation in PA. Specifically, club-based or team-based sport seems to be associated with improved health outcomes compared to individual activities, due to the social nature of the participation. Notwithstanding this, individuals who prefer to participate in sport by themselves can still derive mental health benefits which can enhance the development of true-self-awareness and personal growth which is essential for social health. A conceptual model, Health through Sport, is proposed. The model depicts the relationship between psychological, psychosocial and social health domains, and their positive associations with sport participation, as reported in the literature. However, it is acknowledged that the capacity to determine the existence and direction of causal links between participation and health is limited by the cross-sectional nature of studies to date. CONCLUSION: It is recommended that participation in sport is advocated as a form of leisure-time PA for adults which can produce a range of health benefits. It is also recommended that the causal link between participation in sport and psycho-social health be further investigated and the conceptual model of Health through Sport tested.

A systematic review of the psychological and social benefits of participation in sport for children and adolescents: informing development of a conceptual model of health through sport.

BACKGROUND: There are specific guidelines regarding the level of physical activity (PA) required to provide health benefits. However, the research underpinning these PA guidelines does not address the element of social health. Furthermore, there is insufficient evidence about the levels or types of PA associated specifically with psychological health. This paper first presents the results of a systematic review of the psychological and social health benefits of participation in sport by children and adolescents. Secondly, the information arising from the systematic review has been used to develop a conceptual model. METHODS: A systematic review of 14 electronic databases was conducted in June 2012, and studies published since 1990 were considered for inclusion. Studies that addressed mental and/or social health benefits from participation in sport were included. RESULTS: A total of 3668 publications were initially identified, of which 30 met the selection criteria. There were many different psychological and social health benefits reported, with the most commonly being improved self-esteem, social interaction followed by fewer depressive symptoms. Sport may be associated with improved psychosocial health above and beyond improvements attributable to participation in PA. Specifically, team sport seems to be associated with improved health outcomes compared to individual activities, due to the social nature of the participation. A conceptual model, Health through Sport, is proposed. The model depicts the relationship between psychological, psychosocial and social health domains, and their positive associations with sport participation, as reported in the literature. However, it is acknowledged that the capacity to determine the existence and direction of causal links between participation and health is limited by the fact that the majority of studies identified (n=21) were cross-sectional. CONCLUSION: It is recommended that community sport participation is advocated as a form of leisure time PA for children and adolescents, in an effort to not only improve physical health in relation to such matters as the obesity crisis, but also to enhance psychological and social health outcomes. It is also recommended that the causal link between participation in sport and psychosocial health be further investigated and the conceptual model of Health through Sport tested.

Risk factors for albicans and non-albicans candidemia in the intensive care unit.

OBJECTIVE: To determine risk factors for bloodstream infections (BSI) with Candida non-albicans (C-NA) species and Candida albicans (CA) among critically ill patients. DESIGN: Case-control study. SETTING: Adult medical and surgical intensive care units (ICUs) at two university hospitals. PATIENTS: Consecutive patients with C-NA and CA BSIs from 1995-2005 formed the two case groups. Controls were patients without candidemia who were randomly selected in a ratio of 5:1 and matched by study hospital, ICU type (medical vs. surgical) and by ICU admission date within a 3-month period. INTERVENTIONS: Data collected included demographics, comorbidities, exposure to antibiotics and antifungals, and ICU factors such as total parenteral nutrition (TPN), blood product transfusions, invasive procedures, central venous catheters, hemodialysis, and mechanical ventilation. We built multivariable logistic regression models, which identified risk factors for C-NA or CA BSIs compared with controls. Variables were adjusted for time-at-risk. MEASUREMENTS AND MAIN RESULTS: There were 67 patients with C-NA BSIs, 79 patients with CA BSIs, and 780 controls. In multivariable models, factors associated with an increased risk of C-NA compared with controls included major pre-ICU operations [odds ratio; (95% confidence interval)] [2.12; (1.14-3.97)], gastrointestinal procedures [2.24; (1.49-3.38)], enteric bacteremia [3.43; (1.39-8.48)], number of hemodialysis days [6.20; (2.67-14.4)], TPN duration [2.87; (1.40-5.90)], and mean number of red blood cell transfusions [2.72; (1.33-5.58)]. Factors associated with an increased risk of CA BSIs compared to controls were very similar and included major ICU operations [1.26; (1.14-3.97)], enteric bacteremia [3.45; (1.38-8.63)], number of hemodialysis days [3.84; (1.75-8.40)], TPN duration [11.0; (5.52-21.7)] and mean number of red blood cell transfusions [1.97; (0.98-3.99)]. CONCLUSIONS: We found multiple common risk factors for both non-C. albicans and C. albicans BSIs, however we could not differentiate between these two groups based on clinical characteristics alone.

Experiences of Australian professional female tennis players returning to competition from injury.

BACKGROUND: This study examined the experiences of professional female tennis players returning to competition from injury. METHODS: In a study commissioned by Tennis Australia, 55 Australian professional female tennis players responded anonymously to a questionnaire developed for the purposes of this study. The questionnaire consisted of open and closed questions that assessed a player's attribution style, the occurrence and effect of minor and major injuries, frequency and type of treatment sought, attitudinal chances following injury and preventative injury factors. RESULTS: The quantitative and qualitative analyses of participants' responses revealed players generally displayed an internal attribution style with the majority of minor injuries involving lower limb injuries (attributed to playing on hard surfaces). Players reported these injuries were addressed in a variety of ways including self-treatment. The majority of severe injuries were upper limb/shoulder and these were generally treated at tournament sites with some requiring surgery. CONCLUSIONS: Players adopted a range of measures to assist recovery from severe injury including the services of health professionals. In further findings, a player's attribution style was not a predictive variable, except in terms of the number of tournaments missed for minor injuries. Implications of the study's results and future research directions for cross-cultural studies are highlighted.
