- Description: Objective: To describe and rate the quality of methodological approaches used to measure parental supervision in relation to injury risk in children aged 0-14 years. Design: A systematic review of the literature related to supervision and injury risk. Methods: A comprehensive search of electronic databases from the earliest records available to the end of 2007, and supplemental hand-searching of relevant journals, reference lists of studies identified through database searches, and bibliographies of systematic and non-systematic reviews. A classification scale was used to rate the methodological quality of studies. Results: 30 papers met the inclusion criteria. They varied substantially in quality, and no meta-analyses or randomised controlled trials were identified. Fifteen studies used self-report approaches, asking parents or care givers to report through recording diaries, interviews and questionnaires and were considered of low quality; 11 studies reconstructed injury outcomes retrospectively. Observational studies were conducted in both laboratory and natural settings (n=6), and these studies were generally of higher quality than self-report methods. Conclusions: The quality of many supervision and child injury risk studies is low to moderate. Further development of methodological approaches is needed to improve studies of the relationship between supervision and child injury risk.

- Description: Objectives: To establish how frequently supervision was explicitly identified as a factor in coroner-certified unintentional drowning deaths of children in Australia, and to determine the percentage of cases where failure of supervision may have been a contributing factor; also, to identify the proportion of cases with coroners' recommendations relating to supervision and unintentional child drownings. Design and setting: Retrospective case-series analysis of unintentional drowning deaths of children (aged 0-14 years) in Australia from 1 July 2000 to 30 June 2009, based on data from the National Coroners Information System (NCIS). Main outcome measures: Number of unintentional child drownings and the extent to which supervisory factors were formally reported by coroners as a contributing factor; proportion of cases with coroners' findings that also had coroners' recommendations. Results: 339 relevant child drownings were identified within the 9-year period. Supervision (or lack thereof) was identified as a contributing factor in 71.7%. However, specific detail about the nature and extent of supervision varied across these cases. The availability of text documents describing the findings (police reports, coroners' findings, autopsy reports, toxicology reports), and the level of detail within these documents, also varied considerably across jurisdictions. Despite almost half (47.2%) of the closed cases having coroners' findings attached, only 15% of these also included specific coroners' recommendations. Conclusion: Lack of adequate supervision, or lack thereof, is a significant problem associated with fatal drownings of children in Australia. There is a need to improve the standard and consistency of information contained in text documents within the NCIS to provide more useful information for preventing child drowning deaths.

- Description: This study aimed to determine and compare the nature of supervision children received in two settings that have different levels of environmental risk, an aquatic setting (public pools) and a nonaquatic setting (playgrounds). An observational design was implemented to examine caregiver and child behaviors at six indoor public pools and four playgrounds. Chi-square tests of homogeneity were conducted to determine associations between caregiver and child variables. Preschool children received significantly higher levels of supervision than school-aged children in both settings. For school-aged children the level of supervision varied between settings, with children significantly more likely to be unsupervised in public pools and poorly supervised on playgrounds. Reasons for the lack of supervision in aquatic settings remain unclear, particularly as this setting was considered to present higher environmental risk, because drowning rates are high for young children. Because evidence indicates inadequate supervision is common in aquatic settings, further investigations are required to identify ways to promote closer supervision practices and determine caregiver perceptions regarding their responsibilities when supervising young children in aquatic settings.

BACKGROUND:It is well known that the condition and type of sporting ground influences the risk of sports injury. However, the lack of evidence on the relationship between subjective and objective sporting ground condition assessments in sports injury aetiology studies has implications for the development of effective injury prevention strategies. This paper aims to examine concordance between subjectively rated and objective ground hardness and moisture measurements to inform data collection methods for future sports injury aetiology studies. METHODS:Subjective, observational assessments of ground hardness and soil moisture were recorded on 36 occasions during an Australian football season using two four-point scales of 'very soft' to 'very hard' and 'very wet' to 'very dry', respectively. Independent, objectively measured hardness and soil moisture were also undertaken at nine locations on the same grounds. The maximum and minimum ground values and the computed average of ground hardness and soil moisture were analysed. Somer's d statistic was calculated to measure the level of concordance between the subjective and objective measures. RESULTS:A significant, moderate to substantial level of agreement was found between the subjective ratings and the average objective hardness values (d = 0.467, p <0.001), but there was perfect agreement on just less than half of the occasions. The level of concordance between the subjective and objective moisture ratings was low to moderate or trivial for all moisture measures (0.002
0.05). CONCLUSIONS:Compared to objective measures, the subjective assessments were more accurate for ground hardness than for soil moisture levels and raters were just as likely to underestimate or overestimate the condition under review. This has implications for future sports injury aetiology studies that include ground condition assessments and particularly the use of subjective measures to underpin the development of future injury prevention strategies.

- Description: Objective: To identify independent factors associated with caregiver supervision levels at beaches. Methods: Children (aged 1-14 years) engaged in beach play and their caregivers were observed at Australian beaches during September-April, 2008/09. Caregiver, child, and environmental factor data were collected and recorded on a validated observation instrument. The main outcome of interest was a continuous measure of supervision. After adjusting for potential clustering by beach/state, multivariable linear regression was used to identify independent factors associated with caregiver supervision. Results: Four independent predictors of supervision and one interaction effect (child age by the caregiver and child position on beach) were identified. Caregivers who were supervising from a different position to where the child was playing were less likely to provide high supervision, as were older caregivers (>35 years) compared to younger caregivers (≤34 years). Compared to children playing alone, children playing with one, or two or more others were less likely to receive high supervision, and children aged 1-4 years were likely to receive higher supervision than older children. Conclusion: This study provides new knowledge about underlying factors associated with the level of caregiver supervision in beach settings. Future studies should continue to explore independent predictors of supervision so that effective programmes, which focus on caregiver supervision, can be targeted to address poor supervision practices.

- Description: Rotational resistance is an important sports surface property in optimising both performance and safety for participants. Despite various attempts to create valid devices to measure the rotational traction, the Studded Boot Apparatus (SBA) originally developed in 1975 is still used in the synthetic turf standards of many governing bodies of sport. In addition to validity limitations, poor operator reliability of the SBA has been reported and it was postulated that the manual nature of the device contributed significantly to this result. Therefore, the aim of this paper is to present data on the automation of the SBA and to discuss the reliability and validity issues of the device. An automated version of the SBA was developed called the UB Turf Tester (UBTT) and data was collected by ten inexperienced operators using the original SBA and the UBTT. Testing was undertaken on a synthetic turf and each operator completed ten trials with each device. Despite a slightly greater peak traction value for the UBTT, there was no significant difference between the peak traction for the two devices, F 1,2 = 0.341, p = 0.57. Greater reliability was found between operators for the UB Turf Tester. Given that the SBA is still commonly used to comply with standards, achieving the highest level of intra- and inter-operator reliability is both desirable and invaluable. However, the research on the validity of the device also needs to continue. Interestingly, limitations of the device were identified when it was first developed but very few adaptations have been implemented since then. Undoubtedly, the interaction between the human and the surface is a complex phenomenon but the weight force, the level of penetration, the pattern, shape and position of the cleats and the possibility of measuring rotational stiffness rather than peak traction all require further discussion and investigation.

- Description: The Clegg hammer is currently used to measure hardness of natural turf surfaces to inform performance and safety decisions. However, the number of Clegg hammer drops reported in natural grass testing varies from one to four drops, and the impact of the choice of the number of drops is unknown. The aim of this article is to determine whether significant differences exist between the four Clegg hammer drops on natural grass across a variety of conditions. Hardness readings (using a 2.25 kg Clegg hammer), soil moisture and botanical composition were recorded at nine different sites on seven football fields during an 18-week playing season. A total of 1255 hardness readings were collected for each of four consecutive Clegg hammer drops. Overall, there were significant differences between drop 1 and the other three consecutive drops, on all fields and on all sites. Deep soil moisture was the only factor that significantly influenced the hardness readings. The results of this study demonstrate that the decision regarding the number of drops recorded needs careful consideration as conclusions drawn on playability of a ground or the association with injury risk may vary considerably depending on the number of drops. © 2013 IMechE.

- Description: This study examined self-reported supervisory behaviors of caregivers at beaches and ascertained whether self-reported supervision reflects observed behavior. Observations were conducted of caregiver/child pairs at 18 Australian beaches, with questionnaires subsequently completed by caregivers. Caregivers identified visual contact as essential for close supervision and proximity a key determinant in distinguishing supervision and close supervision. Supervisory behavior was associated with child age, while lifeguard patrol had no effect on supervision. All supervision statements from the PSAPQ-BEACH were associated with supervision. Only three statements were significant independent predictors of supervision. Comparisons suggest caregivers' self-reported supervisory behavior reflects actual supervision. As this is the first study of its kind, it is essential that further prospective research using mixed-method approaches build on this information.

- Description: Due to its associated injury risk, rotational traction is a frequently measured natural turf surface property. The most commonly used equipment, the studded boot apparatus (SBA), consists of a circular stud configuration that does not replicate the stud pattern on a regular football boot and may under or over estimate the surface traction. The aim of this study was to establish potential differences in the rotational traction measured between the current stud configuration on the SBA and the stud configuration on the most commonly used Australian football boots. The original studded boot had significantly higher rotational traction than the moulded stud sole or bladed sole. Location, quality and time tested all interacted significantly with the rotational traction measured. The current SBA may not accurately represent the rotational traction experienced by football players, and consequently may not be the most appropriate configuration to assess the relationship between rotational traction and injuries. © 2012 International Sports Engineering Association.

They varied in methodological quality, with analytical observational studies the most common design, although four descriptive observational studies, considered to be of lower quality were also identified. Only five studies objectively measured ground conditions, and of studies that used subjective assessment, only one provided descriptors to explain their classifications. It appears that harder/drier grounds are associated with an increased injury risk but the presence of major limitations necessitates cautious interpretation of many key findings. Conclusions: There is limited high quality evidence of the relationship between injury risk and ground conditions. Further research with high quality designs, and measurement of ground conditions are required to draw more definitive conclusions regarding this relationship. © 2012.

- Description: Few studies have considered surface temperatures on the most recent synthetic turf products, and no empirical evidence is available on the more technologically advanced cool climate synthetic products which claim to reduce surface temperature. This article compared surface temperatures of typical third-generation synthetic turf with a cool climate product and also compared the synthetic turf products to natural grass to determine whether synthetic turf reacts differently to environmental factors and hence may increase heat-related health risks for participants. Surface temperatures were significantly associated with ambient temperature (F3,376 = 116.02, p < 0.001), relative humidity (F1,376 = 10.15, p = 0.028), and wind (F1,376 = 1.45, p = 0.004) having smaller effects. After adjustment for covariates, mean surface temperatures were significantly lower (40.79 °C) on a cool climate field compared to a typical third-generation field (44.91 °C), although both synthetic fields were considerably warmer than natural grass at the same venue (by 12.46 °C at the metropolitan venue and 22.15 °C at the regional venue). These findings provide initial insight into the potential value of cool climate products and will aid both design and development of synthetic turf products for the future. © IMechE 2014.

Child behavior, corresponding caregiver supervision, and the willingness of parents to intervene when children exhibited unsafe behaviors all were considered. Environmental factors and pool conditions were also recorded. Chi-square tests illustrated that increased supervision was associated with decreased incidents and lower risk behaviors. Supervision was significantly affected by child and caregiver age, number of children for whom caregivers were responsible, and child swimming ability.

- Description: Worldwide, epidemiological data indicate that children are a high-risk group for drowning and while progress has been made in understanding toddler drownings, there is a lack of empirical evidence regarding the drowning risk and protective factors inherent for adolescents and young adults. This study used a self-report questionnaire to establish swimming and water safety knowledge and attitudes of young adults and objectively measured their actual swimming ability using formal practical testing procedures. Participants then completed a short, 12-week intervention that encompassed swimming, survival and rescue skills, along with water safety knowledge applicable to a range of aquatic environments. Knowledge, attitudes and swimming ability were then re-measured following the intervention to evaluate its effectiveness. The Wilcoxon matched pairs signed ranks test was performed to detect whether there were significant differences between knowledge, attitude and swim ability scores pre-intervention and post-intervention. A total of 135 participants completed the baseline and follow up questionnaire and all practical testing. Results indicated that these young adults had a very low level of water safety knowledge pre-intervention, although the majority had sound swimming and water safety skills and attitudes. Overall, significant improvements were evident in knowledge (p < 0.001) and swim ability (p < 0.001) post-intervention, although no changes were observed in attitudes (p = 0.079). Previous participation in formal swimming lessons and/or swimming within the school curriculum had no significant impact on water safety knowledge, skills or attitudes of these young adults, and there were few significant gender differences. While it is important to conduct further studies to confirm that these findings are consistent with a more representative sample of young adults, our findings are the first to provide empirical evidence of the value of a comprehensive aquatic education program as a drowning prevention strategy for young adults.

- Description: Surface temperatures of synthetic turf have become a factor of growing interest and concern, particularly in warmer regions like Australia. However, it is unclear which components of the synthetic turf system contribute to surface temperature. The aim of this paper was to compare the surface temperature of 34 different synthetic turf products that were exposed to the same environmental conditions to ascertain which components of the synthetic turf system and which environmental factors contributed to increased surface temperature. A total of 6,120 observations were taken on the 34 products over the summer months, giving 30 observations for each of the variables on each product. An analysis of covariance (ANCOVA) indicated that the type of infill and shockpad had small-medium, but significant, effects on surface temperature (p<0.001 and p=0.003, respectively), and the interaction between shockpad and tuft gauge was also significant (p=0.047). Level of solar radiation, ambient temperature and relative humidity (p<0.001 in all instances) were the only environmental variables that significantly influenced surface temperature. These findings confirm that both the composition of the synthetic turf system and environmental factors contribute to synthetic turf surface temperature, thus providing important information for synthetic turf manufacturers developing new cool climate products, or for local government authorities selecting products and/or informing safe play for end-users.

- Description: In 1989, it was noted that lapses in parental supervision was the most frequently cited contributory factor in child drownings [1]. Whilst findings from drowning studies completed in the 1980s are now somewhat dated, more recently it has been recognised that further research investigating variations in parental supervision and differences in exposure to water and swimming pools is required [2]. Whilst supervision is ubiquitously mentioned as a contributing factor in child drowning literature, few researchers have attempted to formally define the term [3, 4]. For studies that have provided a definition, all are based on the hierarchical model of supervision that incorporates three dimensions:Attention: visual and auditoryProximity: touching, within reach, beyond reachContinuity: constant, intermittent, absent [5]Based on this model, a combination of all dimensions is required to define supervisory behaviours, with supervision increasing as one or more of the three supervision dimensions increase. Although there is no standardised operational definition of supervision in aquatic settings or other contexts, the hierarchical model appears to provide a sound framework for measuring supervision.
