Epidemiology of Female Youth Ice Hockey Injuries Presenting to United States Emergency Department’s from 2007 to 2016

Objectives: Female youth ice hockey players are an overlooked population. No national study has established incidence rates for injuries in female youth ice hockey. The objective of this study was to establish incidence rates by injury location, diagnosis, and mechanism of injury using USA Hockey sanctioned age divisions. Methods: The National Electronic Injury Surveillance System (NEISS) was queried for all ice hockey injuries (product code 1279) from January 1, 2007 to December 31, 2016. Cases involving players over the age of 19 and males were excluded. Each injury’s narrative text field was reviewed to determine mechanism of injury. Data was analyzed using (IBM®, v24). Comparisons of incidence by age were made using student’s two sample t-test with 95% confidence interval. Trend analyses were performed using a linear regression. USA Hockey membership statistics were used to establish population at risk and calculate incidence rates. All incidence rates were reported per 10,000 person-years. Results: A total of 384 patients, representing an estimated 10,398 ice hockey-related injuries, presented to NEISS-participating United States emergency departments. During the study period, female youth ice hockey players increased significantly from 44,678 in 2007 to 57,792 in 2016 (p=3.9x10-5, R-squared=0.89, ß =0.94). The overall number of injuries, however, only slightly increased from 992 in 2007 to 1,042 in 2016 (p=ns). Thus, the incidence rate (IR) of injuries fell from 222.1 to 180.2 during the study period. The most commonly injured body parts were the head (n=3048, IR=554.5), trunk (n=1399, IR=256.4), knee (n=1127, IR=169), shoulder (n=704, IR=153.3) and ankle (n=591, IR=120.2). The most common diagnoses were strain/sprain (n=2002, IR=417.7), contusion (n=1877, IR= 348), internal organ injury (n=1863, IR=320), concussion (n=1112, IR=218) and fracture (n=1255, IR=202). The top mechanisms of injury were player-to-player contact (n= 3016, IR=535), falls (n=2249, IR=380.9), and contact with boards (n=942, IR=165.8). The incidence rate of injuries increased with age; The 0-8, 9-10, 11-12, 13-14, 15-16 and 17-19 age divisions had IR’s of 24, 84, 226, 381, 360, and 750, respectively. The player-to-player mechanism of injury also increased with age. The largest IR gap between ages fell between the 11-12 and 13-14 age groups, similar to what has been observed in male ice hockey studies. Player-to-player contact is the leading mechanism of injury in all age groups except the 0-8 age group. Head injuries increased with age division: 0-8 (n=15, IR=1), 9-10 (n=153, IR=17.4), 11-12 (n=598, IR=67.2), 13-14 (n=885, IR=115.1), 15-16 (n=650, IR=121.6) and 17-19 (n=746, IR=232.2). The two most common diagnoses of head injuries were concussion (36%) and internal organ injury (61%), both of these diagnoses increasing with age. In fact, concussion diagnosis increased significantly between each age group (p<0.01). Conclusion: We established the first collection of injury incidence rates for female ice hockey gleaned from a national database. Though body checking is illegal at all levels of women’s ice hockey, player-to-player contact prevailed as the leading mechanism of injury in all but the 0-8 age division. It was also the leading mechanism for the most common injury sites, including the head. This study laid bare an unspoken but long understood fact of the girl’s game that body checking is common and major contributor to the game’s injury burden.

The Impact

Background: Body checking is a common cause of youth ice hockey injuries. Consequently, USA Hockey raised the minimum age at which body checking is permitted from the Pee Wee level (11-12 years old) to the Bantam level (13-14 years old) in 2011. Purpose/Hypothesis: The purpose of this investigation was to determine the impact of body checking on the distribution of injuries reported in youth ice hockey players. We hypothesized that the elimination of body checking at the Pee Wee level would lower the frequency of serious injuries, particularly concussions. Study Design: Descriptive epidemiology study. Methods: Injury data from the National Electronic Injury Surveillance System (NEISS), a United States Consumer Product Safety Commission database, were analyzed for Pee Wee and Bantam players between January 1, 2008 and December 31, 2010 and again between January 1, 2013 and December 31, 2015. Data on the location of injury, diagnosis, and mechanism of injury were collected. The location of injury was categorized into 4 groups: head and neck, upper extremity, lower extremity, and core. Diagnoses investigated included concussions, fractures, lacerations, strains or sprains, internal organ injuries, and other. The mechanism of injury was broken down into 2 categories: checking and other. Results: Between the 2008-2010 and 2013-2015 seasons, overall injuries decreased by 16.6% among Pee Wee players, with injuries caused by body checking decreasing by 38.2% ( P = .012). There was a significant change in the distribution of diagnoses in the Pee Wee age group during this time frame ( P = .007): strains or sprains, internal organ injuries, and fractures decreased in frequency, while the number of concussions increased by 50.0%. In the Bantam age group, recorded injuries decreased by 6.8%, and there was no change in the distribution of the location of injury, diagnosis, or mechanism of injury ( P > .05). Conclusion: There was an observed reduction in the total number, mechanism, and type of injuries when body checking was eliminated from the Pee Wee level. There was, however, an unexpected increase in the number of concussions.

The Impact

Abstract Background In response to the recent serogroup W invasive meningococcal disease (IMD-W) epidemic in the Netherlands, meningococcal serogroup C (MenC) conjugate vaccination for 14-month-olds was replaced with a MenACWY conjugate vaccination, and a mass campaign targeting 14-18 year-olds was executed. We investigated the impact of MenACWY vaccination implementation in 2018-2020 on incidence rates and estimated vaccine effectiveness (VE). Methods We extracted all IMD cases diagnosed between July 2014 and December 2020 from the national surveillance system. We calculated age group-specific incidence rate ratios by comparing incidence rates before (July 2017-March 2018) and after (July 2019-March 2020) MenACWY vaccination implementation. We estimated VE in vaccine-eligible cases using the screening method. Results Overall, IMD-W incidence rate lowered by 61% (95%CI 40-74). It declined by 82% (95%CI 18-96) in vaccine-eligible age group (15-36 month-olds and 14-18 year-olds) and by 57% (95%CI 34-72) in vaccine non-eligible age groups. VE was 92% (95%CI -20-99.5) against IMD-W vaccine-eligible toddlers. No IMD-W cases were reported in vaccine-eligible teenagers after the campaign. Conclusions The MenACWY vaccination programme was effective in preventing IMD-W in the target population. The IMD-W incidence reduction in vaccine non-eligible age groups may be caused by indirect effects of the vaccination programme. However, disentangling natural fluctuation from vaccine-effect was not possible. Our findings encourage the use of toddler- and teenager MenACWY vaccination in national immunization programmes especially when implemented together with a teenager mass campaign during an epidemic.

In the current study described in this chapter, we examined the relationship between body image and well-being among religiously observant male and female youth from four age groups: 16, 17, 19, and 22. MANOVA analysis of age x gender produced a significant interaction regarding body image. Various trends were found among the two genders according to age group. Among the girls, there is a moderate rise in body image (BI) with age, whereas among the boys there is an obvious decline between 17 and 19, followed by an increase. The boys' BI scores were significantly higher than those of the girls aged 16, 17, and 19, but not for age 22. There were significant and positive correlations between BI and well-being for all age groups and both genders. There were high correlations among the girls relative to those among the boys.

Socioeconomic Inequity

Abstract Background Hepatitis A (HepA) vaccination and economic transitions can change the epidemiology of HepA. China’s Gross Domestic Product (GDP) per capita was known to be inversely associated with the incidence of HepA, but a deeper understanding of the epidemiology of HepA in different socio-economic regions is lacking. We compare the changing epidemiology of HepA in three socioeconomic-geographic regions of China. Methods We obtained data on all HepA cases reported through the National Notifiable Disease Reporting System and assessed trends and changes in age-specific incidence rates by age quartile and season. We categorized the country into three regions, the sequential years into five era, compared the incidence, quartile age, seasonal intensity and coverage of HepA of the three regions. Linear regression was performed to analyse trends in incidence of HepA and to analyse the association between coverage and incidence. Results The annual mean incidences of HepA in the eastern, central, and western regions decreased from 63.52/100 000, 50.57/100 000 and 46.39/100 000 in 1990–1992 to 1.18/100 000, 1.05/100 000 and 3.14/100 000 in 2012–2017, respectively. Decreases in incidence were seen in all age groups in the three regions; the incidence was highest (9.3/100 000) in the youngest age group (0–4 years) of the western region, while in the central region, the age group with the highest incidence changed from 0 to 9 years to adults ≥60 years old. In 2017, the median age of HepA cases was 43 years (Q1–Q3: 33–55), 47 years (Q1–Q3: 32–60) and 33 years (Q1–Q3: 9–52) in the eastern, central, and western provinces, respectively. Seasonal peaks became smaller or were nearly elimination nationwide, but seasonality persisted in some provinces. After the Expanded Program on Immunization (EPI) included HepA vaccine into the routine schedule in 2007, HepA coverage increased to > 80% in the three regions and was negatively association with the HepA incidence. Conclusion The incidence of HepA decreased markedly between 1990 and 2017. A socioeconomic inequity in coverage of HepA vaccine was almost eliminated after HepA vaccine was introduced into China’s EPI system, but inequity in incidence still existed in lower socio-economic developed region.

Abstract Abstract 3773 Background: Age at diagnosis of CML varies by race in the United States with median occurring around ages 54 and 63 among Black and White patients, respectively. The treatment paradigm shifted when Imatinib was approved in 2001 for treatment of CML. More recently, second generation tyrosine kinase inhibitors (TKI) have also been used for treatment of CML. Differences in outcomes by race have been previously reported prior to the TKI treatment period. We aimed to assess whether the earlier age at diagnosis resulted in differential trends in age-adjusted incidence rates and survival outcomes by race in the post-Imatinib treatment period. Methods: Data from the Surveillance, Epidemiology, and End Results (SEER) 18 Registries were extracted for diagnoses between 2002 and 2009 based on the assumption that cases diagnosed after 2002 would be treated with TKI's. CML was defined according to the International Classification of Diseases for Oncology 3rd edition code 9863 (CML-NOS) and 9875 (CML-Philadelphia Chromosome Positive). Cases diagnosed by autopsy or death certificate only were excluded. Incidence rates are expressed per 100,000 person-years and age-adjusted to the 2000 US Standard Population. Black/White incidence rate ratios (IRRBW) are shown with corresponding 95% confidence intervals (CI). Kaplan-Meier estimates of CML-specific survival (CPS) and overall survival (OS) were estimated at 5-years post-diagnosis with the event being time to CML-specific death or any death, respectively. Stratified Cox proportional hazards models were constructed to assess the impact of age and race on the risk of death expressed as a hazard ratio (HR). Results: Since 2002, 6,632 patients diagnosed with CML were reported to the SEER 18 registries including 5,829 White patients (87.9%) and 803 Black patients (12.1%) with 57% being male. The age-adjusted incidence rate for Blacks was 1.18 (95% CI, 1.10–1.27) per 100,000 and 1.12 (95% CI, 1.09–1.27) per 100,000 for Whites. The corresponding IRRBW was 1.06 (95% CI, 0.98– 1.14). When considering 20-year age-groups, Blacks had higher incidence rates in the 20–39 and 40–59 age groups; IRRBW of 1.26 (95% CI, 1.06–1.49; p=0.0073) and 1.23 (95% CI, 1.09–1.39; p=0.0007), respectively. No statistically significant differences in IRRBW were seen within the 0–19, 60–79 and 80+ age-groupings although Whites have higher non-significant incidence rates in the latter 2 age-groups. Differences in IRRBW prompted an assessment of survival to determine if the excess incidence observed in the younger age groups corresponded with a worse survival. CPS at 5-years was 85.5% (95% CI, 84.3–86.6). In univariate analysis, age was an important predictor of outcome (p<0.0001) with patients diagnosed after age 80 having the worse outcomes (OS: 58.3%), followed by patients diagnosed between 60 and 79 years (OS 84.7%), 0–19 years (OS: 87.1%), 40–59 years (OS: 90.2%), and 20–39 years (OS: 92.6%). When considering all age-groups, race was not a significant predictor of death (HR 0.91; 95% CI, 0.72–1.15). However, in a stratified analysis with 20-year age groups, Blacks had an increased risk of death as compared to Whites (Figure 1) in the 20–39 age group (HR: 2.94; 95% CI, 1.72–5.26; p<0.0001) and the 40–59 age group (HR: 1.67; 95% CI, 1.22–2.27; p=0.0069) while no differences were seen within the 0–19, 60–79 and 80+ age groups. Conclusions from OS models were similar to that of the CPS models. Conclusions: Through this analysis of population-based cancer registry data collected in the US between 2002 and 2009, we show that Blacks have a younger age at diagnosis with higher incidence rates observed in the 20–39 and 40–59 age-groups as compared to Whites. Both CPS and OS outcomes differed by race and age. Similar to the differences observed with the incidence rates, survival was worse in Blacks diagnosed within the 20–39 and 40–59 age-groups as compared to Whites. Although outcomes have globally improved in patients with CML since the advent of tyrosine kinase inhibitors, the persistence of incidence heterogeneity and poorer survival among Blacks warrants further attention. Access to care may be a possible reason for the differences observed but further studies are warranted to rule out biological differences which may be causing an earlier age at onset and poorer survival. Disclosures: No relevant conflicts of interest to declare.

e12570 Background: Breast cancer (BC) is the second most common malignancy and the leading cause of death by cancer in Peruvian women (age-standarized rate [ASR] of 34 new cases/100,000 women estimated by GLOBOCAN 2008). The purpose of this study was to assess the incidence of BCin acohort ofwomenat Oncosalud, an oncologic pre-paid system that currently has 600,000 affiliates. Methods: We evaluated a dynamic cohort (period 1989 to 2011) of women affiliatedat Oncosalud – AUNA, an oncologic prepaid system.The crude incidence rate per year (number of new cases/women at risk), the specific rate according to age (number of new cases / persons-year) and cumulative risk were calculated. Results: Overall, during the assessment period, the BC incidence rate per year was 175.6 and the ASR incidence was 111.9 per 100,000 affiliates respectively. In our cohort of affiliates there were no BC cases before 1993 (with 907 women at risk for that year). The highest incidence rate was 177.6 registered in 1997 (11,822 women at risk). Incidence rates started decreasing in 2003 (169.2 with a population at risk of 39,593 women). The lowest incidence was 71.5, registered in 2011 (279,680 women at risk).According to age-groups, there were no BC cases under20 years old. Specificincidence ratesper age-group increases from the 30 year old-group (55.8). The peak of BC incidence was between 70 to 74 years old (407.4). In the same way, the cumulative risk increases after 30 years old. Conclusions: In our cohort of affiliates, the incidence of BC is greater than the general population, it could be due to the process of negative selection; however, specific incidence rates per age-group and cumulative risk are increased after 30 years, as seen in the general population.

Predictive Approaches

Strategies adopted globally to mitigate the threat of COVID–19 have primarily involved lockdown measures with substantial economic and social costs with varying degrees of success. Morbidity patterns of COVID–19 variants have a strong association with age, while restrictive lockdown measures have association with negative mental health outcomes in some age groups. Reduced economic prospects may also afflict some age cohorts more than others. Motivated by this, we propose a model to describe COVID–19 community spread incorporating the role of age-specific social interactions. Through a flexible parameterisation of an age-structured deterministic Susceptible Exposed Infectious Removed (SEIR) model, we provide a means for characterising different forms of lockdown which may impact specific age groups differently. Social interactions are represented through age group to age group contact matrices, which can be trained using available data and are thus locally adapted. This framework is easy to interpret and suitable for describing counterfactual scenarios, which could assist policy makers with regard to minimising morbidity balanced with the costs of prospective suppression strategies. Our work originates from an Irish context and we use disease monitoring data from February 29th 2020 to January 31st 2021 gathered by Irish governmental agencies. We demonstrate how Irish lockdown scenarios can be constructed using the proposed model formulation and show results of retrospective fitting to incidence rates and forward planning with relevant “what if / instead of” lockdown counterfactuals. Uncertainty quantification for the predictive approaches is described. Our formulation is agnostic to a specific locale, in that lockdown strategies in other regions can be straightforwardly encoded using this model.

Athletic Development

Physical conditioning is crucial in building motion skills if the coach wants to ensure long-term athletic development. The essence is that physical conditioning needs to be developed before the development of technical skills of sports movements at a much higher intensity at each stage of the multi-annual training process. The adult competition system and training programs are being imposed on young athletes, so the essential motion skills are not being learned (Grāvītis @ Luika, 2015). The lack of physical conditioning in teenage years is very often reflected in the most inappropriate moments of an athlete's career, at the elite level. Insufficient physical conditioning is a reason for the instability of motion skills and injuries in extreme physical and psychological loads. The amount of physical activity can be measured as a step count. The aim of the research is to assess physical fitness rate for children practicing basketball, football or ice hockey with EUROFIT test battery. The study included boys, 100 basketball players, 100 soccer players and 100 ice hockey players from Latvia who were born in 2002 and started training in their sport during at the ages from 7 to 9, collected data of their conditioning for five years, divided into three age groups. According to EUROFIT tests, it was concluded that the ice hockey players have the highest physical conditioning rates according to EUROFIT standard from the athletes analyzed, and the basketball players have the lowest physical conditioning rates in EUROFIT tests from the athletes analyzed. We can conclude that the results of hockey players are higher than the scores of basketball and soccer players because ice hockey players practice more frequently, and dryland training is strictly organized, they develop all motor abilities that is needed for successive training in basic drills on ice.

Abstract Background . There is evidence that males have higher incidence rates (IR) of campylobacteriosis than femlaes. The objectives of this study were to determine whether the sex differences differ between age groups and are consistent over different countries and over different time periods. Methods. We obtained data on incidence rates of campylobacteriosis by sex and age group over a period of 11-26 years from seven countries. Male to female incidence rate ratios (IRR) were computed by age group, country and time period. For each age group, we used meta-analytic methods to combine the IRRs. Sensitivity analysis was used to test whether the results are robust to differences between countries and time periods. Meta-regression was conducted to estimate the different effects of age, country, and time period on the IRR. Results . In the age groups <1, 1-4, 5-9, 10-14, 15-44, 45-64 and 65+ years old, the pooled IRRs (with 95% CI) were 1.31 (1.26-1.37), 1.34 (1.31-1.37), 1.35 (1.32-1.38), 1.73 (1.68-1.79), 1.10 (1.08-1.12), 1.19(1.17-1.21) and 1.27 (1.24-1.30), respectively. For each age group, the excess campylobacteriosis incidence rates in males differed at different age groups. However, despite some quantitative differences between countries, the excess was consistently present over long time-periods. In meta-regression analysis, age group was responsible for almost all the variation in the IRRs. Conclusions . The male predominance in campylobacteriosis incidence rates starts in infancy. This suggests that this is due, at least in part, to physiological or genetic differences and not just behavioural factors. These findings can provide clues to the mechanisms of the infection and could lead to more targeted treatments and vaccine development.
