Gambling Habits and Attitudes among Athlete and Non-Athlete High School Students in Skåne Region, Sweden.

Previous literature has reported increased rates of gambling problems in athletes compared to non-athletes. More liberal gambling-related attitudes have been suggested as a reason, although this rarely has been researched. The present study aimed to examine gambling experience, gambling problems, and gambling-related attitudes and parental gambling experience in high school students, comparing student-athletes to students at conventional schools. This is a cross-sectional web survey study in high school students (N = 473, 53% at sports high schools, 57% male) at eleven schools in the Skåne region, Sweden, who answered a web survey addressed gambling experiences, parental gambling and gambling-related attitudes, and included validated screening instruments for gambling problems and psychological distress. A history of any gambling was common and increased with age. Problem gambling was detected in 10% (13% of males and 5% of females, p < .001), and was associated with paternal and maternal gambling but not with psychological distress. Sports high school students were not more likely (9%) than other students (10%) to endorse gambling problems and history of each gambling type. However, paternal (but not maternal) gambling was more commonly reported in athletes, who also had more positive attitudes to gambling's effects on society and gambling availability. In contrast to other studies, this study did not demonstrate higher prevalence of gambling or gambling problems among young athletes than among other students, but liberal attitudes towards gambling, and experience of parental gambling on the father's side, were more common among athletes than among non-athletes. Gambling attitudes in adolescents may need to be targeted in future preventive efforts in young athletes and others.

Secondary School Athletic Trainers' Strategies and Barriers to Overuse Injury Treatment in Adolescent Athletes.

CONTEXT: Studies have illustrated that overuse injuries occur in adolescent athletes more often than previously reported. The general purpose of this study was to provide a thorough report of secondary school athletic trainers encounters, practices, and perceptions of overuse injury in adolescent athletes. DESIGN: Cross-sectional. METHODS: An anonymous online questionnaire was distributed via email to athletic trainers in the secondary school setting. The questionnaire was sent to participants during the summer of 2021 and 430 participants (highest educational degree earned: master's degree = 66%) completed the survey. Various survey methods were used to evaluate athletic trainers (1) demographics, (2) estimations about what percentage of injuries evaluated and treated were classified as overuse, (3) methods for treating overuse injuries, (4) confidence in treating overuse injuries and the complete implementation of their treatment plan, (5) perceptions of various barriers to treating overuse injuries, and (6) perception as to why patients did not want to reduce activity to treat their overuse injuries. RESULTS: Participants reported that about half of all evaluations and treatments in a year were overuse injuries and they were "fairly" or "completely" confident (90%) in their ability to treat these injuries. The most common treatments cited were stretching (91%) and reducing activity (90%). Only 61% of participants were "fairly" or "completely" confident in the complete implementation of their treatment plan. Participants believed that patients' reluctance to reduce sport activities (82% "moderate" or "extreme" barrier) was the most significant barrier to treatment. Participants cited athletes' avoidance of missing games as the most common reason athletes were reluctant to reduce sporting activity. CONCLUSIONS: Participants felt confident in treating overuse injuries yet faced significant barriers in treating these injuries. Clinicians should be prepared to have conversations about the importance of reducing sporting activity to allow proper healing for overuse injuries in adolescent athletes.

The Initiation and Developmental Course of Prescription Drug Misuse Among High School Athletes During the Transition Through Young Adulthood.

The objective of this study was to examine the extent to which involvement in high-contact, semicontact, or noncontact sports during the 12th grade is associated with the initiation and developmental course of prescription drug misuse (PDM) between ages 17/18 years and 27/28 years. Data were collected from a national multicohort panel sample of US 12th-graders (cohorts 2006-2017; n = 4,772) from the Monitoring the Future Study who were followed for a decade, through age 27/28 years. Approximately 31% of high school seniors indicated PDM at baseline (age 17/18 years). While past-year PDM remained relatively stable between ages 17/18 years and 27/28 years, participation in both noncontact (adjusted odds ratio = 1.40, 95% confidence interval: 1.02, 1.91) and contact (adjusted odds ratio = 1.57, 95% confidence interval: 1.08, 2.28) sports in the 12th grade increased the odds of initiating prescription stimulant misuse during the 10 years following high school as compared with respondents who did not participate in these types of sports in the 12th grade. To our knowledge, this is the first national study to have assessed how sports participation during high school is associated with the initiation and developmental course of PDM from adolescence to young adulthood. These findings reinforce the need for PDM screening during adolescence, as nearly 1 in 3 high school seniors engage in PDM. Increased prescription stimulant misuse following high school warrants ongoing monitoring during young adulthood, especially among athletes.

Healthcare professional involvement and RTP compliance in high school athletes with concussion.

OBJECTIVES: To describe concussion rates in high school athletes and involvement of healthcare professionals in concussion diagnosis, management and compliance with return to play (RTP) guidelines. METHODS: Data were analysed from injury reports in the National High School Sports-Related Injury Surveillance System between 2009/2010 and 2012/2013 to identify student athletes with concussion and determine compliance with RTP guidelines. Compliance with RTP guidelines was examined using logistic regression, adjusting for sport and injury-related variables. RESULTS: There were 5611 concussions recorded during 15 712 475 athlete exposures (AEs), a rate of 3.6 concussions per 10 000 AEs. Rates were higher during competition and among girls compared to boys in gender equitable sports. Healthcare professionals were less likely to be present at the time of concussion for girls' sports, lower competition levels and practices. Compliance with RTP guidelines was higher for athletes with recurrent concussions, those sustained in collision sports, for athletes reporting more symptoms and when a physician made the RTP decision. CONCLUSIONS: Presence of healthcare professionals and compliance with RTP guidelines varied by sport, gender, level of play and exposure type. High school athletes with concussion are best served by assessment teams with athletic trainers and physicians working together to manage concussions and contribute to RTP decisions.

Epidemiology of meniscal injuries in US high school athletes between 2007 and 2013.

PURPOSE: Knowledge of epidemiologic trends of meniscal injuries in young active populations is limited. Better awareness of injury patterns is a first step to lowering injury rates. Our hypothesis was that meniscal injuries in high school athletes would vary by gender, sport, and type of exposure. METHODS: During the 2007/2008 and 2012/2013 academic years, a large nationally disperse sample of US high schools reported athlete exposure and injury data for 22 sports by having certified athletic trainers complete an internet-based data collection tool. RESULTS: One thousand and eighty-two meniscal injuries were reported during 21,088,365 athlete exposures for an overall injury rate of 5.1 per 100,000 athlete exposures. The overall rate of injury was higher in competition (11.9) than practice (2.7) (RR = 4.4; 95% CI 3.9-5.0), and 12/19 sports showed significantly higher injury rates in competition compared to practice. Of all injuries, 68.0% occurred in boys, yet among the gender-comparable sports of soccer, basketball, track and field, lacrosse, and baseball/softball injury rates were higher for girls than boys (5.5 and 2.5, respectively, RR = 2.2; 95% CI 1.8-2.7). Contact injury represented the most common mechanism (55.9%). Surgery was performed for the majority of injuries (63.8%), and 54.0% of athletes had associated intra-articular knee pathology. CONCLUSIONS: Meniscal injury patterns among high school athletes vary by gender, sport, and type of exposure. Our study is clinically relevant because recognition of distinct differences in these injury patterns will help drive evidence-based, targeted injury prevention strategies and efforts. LEVEL OF EVIDENCE: III.

Epidemiology of Sports Injuries Among High School Athletes in the United States: Data From 2015 to 2019.

Background: Nearly 8 million high school students in the United States participate in sports each year. With the lack of recent population data, an update to previous studies on US high school athletes is needed. Purpose: To update the epidemiology of sports injuries in high school athletes in the United States. Study Design: Descriptive epidemiology study. Methods: The data from the National Health School Sports-Related Injury Surveillance Study, including 100 nationally representative high schools, were obtained for 9 high school sports (boys' football, soccer, basketball, wrestling, and baseball and girls' soccer, basketball, volleyball, and softball) between the 2015 and 2019 academic years. Injury rates were calculated as the ratio of injuries per 1000 athlete exposures (AEs), defined as 1 athlete participating in 1 practice or competition. Data on injured body area, injury type (sprains/strains, concussions, contusions, and fractures), time loss, and need for surgery were also obtained. Rate ratios (RRs) with 95% CIs and P values were calculated. Results: Athletic trainers reported 15,531 injuries during 6,778,209 AEs, with an overall rate of 2.29 injuries per 1000 AEs. Injury rates were highest in football (3.96), girls' soccer (2.65), and boys' wrestling (2.36). The overall injury rate was lower in girls' sports (1.86) compared with boys' sports (2.52) (RR, 0.74 [95% CI, 0.71-0.76]; P < .001) and was higher in competition compared with practice (RR, 3.39 [95% CI, 3.28-3.49]; P < .001). The most commonly injured body areas were the head/face (24.2%), ankle (17.6%), and knee (14.1%). Sprains/strains (36.8%) and concussions (21.6%) were the most common diagnoses. Overall, 39.2% and 34% of injuries resulted in a time loss of <1 week and 1 to 3 weeks, respectively. Surgery was required in 6.3% of injuries, with wrestling (9.6%), girls' basketball (7.6%), and boys' baseball (7.4%) being the sports with the highest proportion of injuries needing surgery. Conclusion: Study findings demonstrated that boys' football, girls' soccer, and boys' wrestling had the highest injury rates, with boys' sports overall having higher injury rates than girls' sports. Sprains/strains and concussions were the most common diagnoses. Few injuries required surgery.

Prevalence of stress amongst high school athletes (v2).

Objective: This study sought to 1) ascertain the severity of the stress experienced by high school athletes due to playing a sport, 2) understand how these athletes deal with their stress, and if these athletes desire help from someone and 3) determine whether athletes consider their stress a debilitating factor. Methods: 200 high school athletes between the ages of 16 and 17 were surveyed using an anonymous online survey platform to discover the relationship between stress and sports. The survey examined both male and female athletes from a variety of sports, different locations, and different ethnicities. Results: Approximately 91% of all the cohort experienced some level of stress due to sports. Interestingly, about a third claimed stress positively affected performance. Fear of failure and self-pressure were the most common causes of stress. About 27% who were experiencing moderate to extreme stress wanted, but did not receive, help from a medical professional. However, of all the participants who experienced some level of stress, only 18% believed that receiving help from a medical professional would not be beneficial for them. Conclusion: While it is easy to overlook and minimize the stress of a high school athlete, doing so may cause future problems such as anxiety and depression, both of which have been steadily increasing among that same population. It is important that, if needed, these athletes have access to medical professionals to adequately manage their stress.

Concussion Symptomology By Symptom Resolution Time in US High School Athletes: Findings From The National Athletic Treatment, Injury and Outcomes Network (NATION) High School Surveillance Program.

CONTEXT: Concussions incurred during high school athletics are a significant health concern, and studies examining concussions with symptom resolution time (SRT) of 15-28 days have been limited. OBJECTIVE: To compare concussions that had a SRT of 15-28 days with concussions that had a SRT of >28 days among US High School athletes. DESIGN: Descriptive epidemiology study. SETTING: Secondary school athletic training clinics. PATIENTS OR OTHER PARTICIPANTS: Secondary school athletes. MAIN OUTCOME MEASURE(S): Concussion frequency, symptom number, and symptom prevalence. RESULTS: Among all 917 reported concussions (of which 50.8% had missing SRT), 88 had SRT recorded as 15-28 days and 29 had SRT recorded as >28 days. Greater frequencies of concussions with SRT >15 days were reported among boys' sports (n= 78) than girls' sports (n= 39). Boys' football (51.7%) and girls' basketball (11.5%) accounted for the largest proportions of all reported concussions with SRT of 15-28 days; boys' football (58.6%) accounted for the greatest proportion of concussions reported with SRT >28 days. The average number of symptoms in concussions with SRT of 15-28 days was 6.3±3.4 and 7.2±3.8 in those with SRT >28 days. The most frequently reported symptoms in concussions with both SRT of 15-28 days and >28 days were headache, dizziness, sensitivity to light, and difficulty concentrating. The prevalence of irritability was higher in concussions with SRT of 15-28 days as compared to concussions with SRT >28 days (26.1% vs. 13.8%); visual problems (48.3% vs. 35.2%) and hyperexcitability (24.1% vs. 15.9%) were more prevalent in concussion with SRT >28 days, although differences were not statistically significant. CONCLUSIONS: Symptom prevalence and total count were comparable between concussions with SRT of 15-28 days and >28 days with no statistically significant difference, suggesting symptom burden within these groups are more similar than they are different.

Visuo-vestibular and cognitive connections of the vestibular neuromatrix are conserved across age and injury populations.

BACKGROUND AND PURPOSE: Given the prevalence of vestibular dysfunction in pediatric concussion, there is a need to better understand pathophysiological disruptions within vestibular and associated cognitive, affective, and sensory-integrative networks. Although current research leverages established intrinsic connectivity networks, these are nonspecific for vestibular function, suggesting that a pathologically guided approach is warranted. The purpose of this study was to evaluate the generalizability of the previously identified "vestibular neuromatrix" in adults with and without postconcussive vestibular dysfunction to young athletes aged 14-17. METHODS: This retrospective study leveraged resting-state functional MRI data from two sites. Site A included adults with diagnosed postconcussive vestibular impairment and healthy adult controls and Site B consisted of young athletes with preseason, postconcussion, and postseason time points (prospective longitudinal data). Adjacency matrices were generated from preprocessed resting-state data from each sample and assessed for overlap and network structure in MATLAB. RESULTS: Analyses indicated the presence of a conserved "core" network of vestibular regions as well as areas subserving visual, spatial, and attentional processing. Other vestibular connections were also conserved across samples but were not linked to the "core" subnetwork by regions of interest included in this study. CONCLUSIONS: Our results suggest that connections between central vestibular, visuospatial, and known intrinsic connectivity networks are conserved across adult and pediatric participants with and without concussion, evincing the significance of this expanded, vestibular-associated network. Our findings thus support this network as a workable model for investigation in future studies of dysfunction in young athlete populations.

The Effect of COVID-19 Lockdown on PHQ Depression Screening Scores for High School Athletes.

Adolescent behavioral health was in crisis before COVID-19. The shutdown and reopening of in-person learning and extracurricular activities may have worsened this crisis. We examined high school athletes' depression before and during the pandemic. Data were collected as part of a pilot program incorporating Patient Health Questionnaire (PHQ) screenings during high school sports physicals before the COVID-19 lockdown and three timepoints after. Statistical comparisons were made using logistic regression. A total of 927 individual scores were analyzed: 385 from spring 2020; 145 from fall 2020; 163 from fall 2021; and 234 from spring 2022. Fall 2020 students were 3.7 times more likely to have elevated PHQ-2 scores than spring 2020 students (95% CI = 1.8, 7.6). Fall 2021 and spring 2022 scores did not differ significantly from pre-pandemic, although trends of elevated scores persisted (OR = 1.6; 95% CI = 0.7, 3.5, and OR = 1.2; 95% CI = 0.6, 2.4, respectively). A significant difference in PHQ-9 depression severity classification was detected over time (p < 0.01). Elevated PHQ scores were found after the onset of the COVID-19 pandemic. After the initial peak in fall 2020, scores decreased but did not reach pre-pandemic levels.

Epidemiology of Lower Leg Soft Tissue Injuries in High School Athletes.

BACKGROUND: Annually there are an estimated 4.5 million sports- and recreation-related injuries among children and young adults in the United States. The most common sports-related injuries are to the lower extremities, with two-thirds occurring among children and young adults (age range 5-24 years). The objective is to describe the epidemiology of lower leg injuries across 27 high school (HS) sports over a 3-year period. METHODS: The Datalys Center for Sports Injury Research and Prevention provided lower leg injury data for 27 sports in 147 high schools for 2011-2012 through 2013-2014 academic years from National Athletic Treatment, Injury and Outcomes Network (NATION) HS Surveillance Program. RESULTS: The overall rate of lower leg injuries over this 3-year period was 1.70 per 10 000 acute events (AEs) (95% CI, 1.59-1.82). In men, the highest number of lower leg injuries was in football (n=181), but indoor track had the highest rate of injury at 2.80 per 10 000 AEs (95% CI, 2.14-3.58). In women, the highest number of lower leg injuries and the highest rate of injury were in cross-country (n=76) at 3.85 per 10 000 AEs (95% CI, 3.03-4.81). The practice injury rate was 0.91 times the competition injury rate (95% CI, 0.78-1.07). CONCLUSION: An improved understanding of the most common sports in which lower leg injuries are seen may help direct appropriate resource utilization. Our data would suggest efforts toward prevention of these overuse injuries, especially in football, track, and cross-country may have the greatest impact on the health of student athletes. LEVEL OF EVIDENCE: Level IV, case series.

Epidemiology of Overuse Injuries in US Secondary School Athletics From 2014-2015 to 2018-2019 Using the National Athletic Treatment, Injury and Outcomes Network Surveillance Program.

CONTEXT: With 8 million annual US high school student-athletes, the epidemiology of sport-related injuries has garnered significant interest. The most recent studies examining overuse injury rates in high school sports were based on data from 2012 to 2013 and, therefore, may not reflect current overuse injury rates in high school sports. OBJECTIVE: To (1) determine overuse time-loss (TL) and non-time-loss (NTL) injury rates among high school student-athletes using National Athletic Treatment, Injury and Outcomes Network Surveillance Program (NATION-SP) data collected from 2014-2015 to 2018-2019 and (2) compare overuse injury rates based on student-athlete sex defined by whether it was a boys' sport or a girls' sport, the sport itself, and the injury location. DESIGN: Descriptive epidemiology study. SETTING: Online injury surveillance from 211 high schools (345 individual years of high school data). PATIENTS OR OTHER PARTICIPANTS: Athletes who participated in secondary school-sponsored boys' or girls' sports. MAIN OUTCOME MEASURE(S): Boys' and girls' overuse injury data from the NATION-SP during the 2014-2015 to 2018-2019 school years were analyzed. Overuse injuries were identified using a combination of the reported injury mechanism and diagnosis. Time-loss injuries resulted in restriction from participation beyond the day of injury; NTL injuries did not result in restriction from participation beyond the day of injury or involved no lost time due to the injury. Injury counts, rates, and rate ratios (IRRs) were reported with 95% CIs. RESULTS: The total overuse injury rate was 5.3/10 000 athlete-exposures (AEs; 95% CI = 5.1, 5.7), the NTL overuse injury rate was 3.4/10 000 AEs (95% CI = 3.1, 3.6), and the TL overuse injury rate was 2.0/10 000 AEs (95% CI = 1.8, 2.2). The overuse injury rate was greater in girls' sports compared with boys' sports (IRR = 1.9; 95% CI = 1.7, 2.1). The highest rates of overuse injury were observed in girls' cross-country (19.2/10 000 AEs; 95% CI = 15.0, 24.2), girls' track and field (16.0/10 000 AEs; 95% CI = 13.5, 18.8), and girls' field hockey (15.1/10 000 AEs; 95% CI = 10.2, 21.6). Overuse injury rates were higher for the lower extremity than the upper extremity (IRR = 5.7; 95% CI = 4.9, 6.7) and for the lower extremity than the trunk and spine (IRR = 8.9; 95% CI = 7.3, 10.8). CONCLUSIONS: Awareness of the overuse injury risk, as well as prevention and intervention recommendations, is necessary and should be specifically targeted at cross-country, field hockey, and track and field athletes.

An epidemiologic comparison of acute and overuse injuries in high school sports.

BACKGROUND: Acute and overuse injuries affect millions of high school athletes annually and a better understanding of differences between these injuries is needed to help guide prevention, treatment, and rehabilitation strategies. This study compares acute and overuse injuries using a nationally representative sample of high school athletes. METHODS: Injuries among United States high school athletes participating in 5 boys' sports (football, soccer, basketball, wrestling, baseball) and 4 girls' sports (soccer, volleyball, basketball, softball) reported in the High School RIO™ surveillance system during the 2006-07 through 2018-19 school years were classified as acute or overuse. National estimates and injury rates were calculated. RESULTS: Of 17 434 646 estimated injuries, 92.0 % were acute and 8.0 % were overuse. The acute injury rate was higher than the overuse injury rate among both male (Rate Ratio [RR] 16.38, 95 % CI: 15.70-17.10) and female (RR 8.14, 95 % CI: 7.71-8.60) athletes. The overuse injury rate per 10,000 athlete exposures among female athletes (1.8) was slightly higher than among males (1.4). The rate of acute injury compared with the rate of overuse injury was higher during competition (RR 32.00, 95 % CI: 29.93-34.22) than practice (RR 7.19, 95 % CI: 6.91-7.47). Boys' football contributed the most acute (42.1 %) and overuse (23.7 %) injuries among the 9 sports. Among female sports, girls' soccer contributed the most acute (15.6 % of all acute injuries) and overuse (19.4 % of all overuse injuries) injuries. The lower extremity was most commonly injured in acute (48.9 %) and overuse (65.9 %) injuries. Ligament sprain (31.7 %) and concussion (21.0 %) were the most common acute injury diagnoses, while muscle strain (23.3 %) and tendonitis (23.2 %) were the most common overuse injury diagnoses. Compared with acute injuries, overuse injuries were more likely to result in time loss from sports participation of < 1 week among both boys and girls and across most sports. Acute injuries were more likely than overuse injuries to cause a time loss of 1-3 weeks or medical disqualification from sports participation. CONCLUSIONS: Acute and overuse injuries display many differences that provide opportunities for data-informed athlete preparation, treatment, and rehabilitation, which may reduce injuries and improve injury outcomes in high school athletics.

Association Between Design Elements of Concussion Laws and Reporting of Sports-Related Concussions Among US High School Athletes, 2009-2017.

OBJECTIVES: Studies that evaluate the effectiveness of concussion laws often use only a single variable (ie, presence of the law), failing to account for law complexity. We examined the association between multiple design elements of state concussion laws and rates of sports-related concussion reporting among US high school athletes. METHODS: We derived 3 design elements of concussion laws from the 2009-2017 LawAtlas database: (1) strength of law, (2) number of law revisions, and (3) speed of law adoption. We examined the association between these design elements and rates of new and recurrent sports-related concussion reporting from the 2009-2010 through 2016-2017 academic years in a nationally representative sample of high school athletes participating in High School Report Information Online, an online data collection tool. RESULTS: A total of 7064 sports-related concussions (6332 [89.6%] new and 732 [10.4%] recurrent concussions) were reported during the study period, with an overall rate of 39.7 sports-related concussions per 100 000 athletic exposures (eg, game or practice). Rates of new concussion reporting were higher among high schools in states with medium- or high-strength concussion laws than in states with low-strength concussion laws and in states with at least 1 concussion law revision than in states with no concussion law revisions. Rates of recurrent concussion reporting were lower among high schools in states with ≥2 concussion law revisions than in states with <2 concussion law revisions. Early law adoption was associated with higher rates of new and recurrent concussion reporting, and late law adoption was associated with lower rates of new and recurrent concussion reporting. CONCLUSION: Our findings may help inform legislators of the public health effect of concussion laws.

Changes in the Health of Adolescent Athletes: A Comparison of Health Measures Collected Before and During the COVID-19 Pandemic.

CONTEXT: In spring 2020, schools closed to in-person teaching and sports were cancelled to control the transmission of COVID-19. The changes that affected the physical and mental health among young athletes during this time remain unknown. OBJECTIVE: To identify changes in the health (mental health, physical activity, and quality of life) of athletes that occurred during the COVID-19 pandemic. DESIGN: Cross-sectional study. SETTING: Sample recruited via social media. PATIENTS OR OTHER PARTICIPANTS: A total of 3243 Wisconsin adolescent athletes (age = 16.2 ± 1.2 years, 58% female) were surveyed in May 2020 (During COVID-19). Measures for this cohort were compared with previously reported data for Wisconsin adolescent athletes (n = 5231; age = 15.7 ± 1.2 years, 47% female) collected in 2016 to 2018 (PreCOVID-19). MAIN OUTCOME MEASURE(S): Demographic information included sex, grade, and sport(s) played. Health assessments included the Patient Health Questionnaire-9 Item to identify depression symptoms, the Pediatric Functional Activity Brief Scale to gauge physical activity, and the Pediatric Quality of Life Inventory 4.0 to evaluate health-related quality of life. Univariable comparisons of these variables between groups were conducted via t or χ2 tests. Means and 95% CIs for each group were estimated using survey-weighted analysis-of-variance models. RESULTS: Compared with preCOVID-19 participants, a larger proportion of During COVID-19 participants reported moderate to severe levels of depression (9.7% versus 32.9%, P < .001). Scores of the During COVID-19 participants were 50% lower (worse) on the Pediatric Functional Activity Brief Scale (mean [95% CI] = 12.2 [11.9, 12.5] versus 24.7 [24.5, 24.9], P < .001) and the Pediatric Quality of Life Inventory 4.0 compared with the PreCOVID-19 participants (78.4 [78.0, 78.8] versus 90.9 [90.5, 91.3], P < .001). CONCLUSIONS: During the COVID-19 pandemic, adolescent athletes described increased symptoms of depression, decreased physical activity, and decreased quality of life compared with adolescent athletes in previous years.

Reducing Alcohol Use among High School Athletes: A Randomized Controlled Trial of a Brief, Web-Based Personalized Normative Feedback Intervention.

High school athletes are at risk for heavy alcohol use, which is associated with consequences that may negatively impact performance and eligibility to participate in sports. This study evaluated the efficacy of a web-based personalized normative feedback (PNF) intervention on reducing alcohol use among high school athletes in their senior year. Class periods were randomized to the intervention or an assessment-only control group. Athletes completed surveys at baseline and a 6-week follow-up. Athletes were classified as high-risk or low-risk drinkers based on baseline reports of binge drinking. Results indicated for athletes classified as high-risk drinkers, those in the intervention group reported significantly greater reductions in quantity of weekly drinking and peak drinking quantity compared to those in the assessment-only control group. There were no significant intervention effects for frequency of alcohol use. Findings provide support the efficacy of web-based PNF intervention for reducing alcohol use among high school senior athletes.

Shoulder dislocations among high school-aged and college-aged athletes in the United States: an epidemiologic analysis.

HYPOTHESIS/BACKGROUND: Shoulder dislocations are common orthopedic injuries due to the mobile nature of the glenohumeral joint. High school and collegiate athletes are at particularly high risk for sustaining a dislocation event. Despite the prevalence of these injuries, there is a paucity in the literature regarding incidence of sports-related shoulder dislocations and mechanism of injury within these populations. Therefore, the aim of the present study was to (1) determine the incidence rate of shoulder dislocations in high school-aged and collegiate-aged athletes presenting to emergency departments (EDs) in the United States; (2) to determine the most common sports associated with shoulder dislocations; and (3) to compare the current rates and risk factors for shoulder dislocation with previous trends. METHODS: The National Electronic Injury Surveillance System is a statistically validated injury surveillance system that collects data from ED visits as a representative probability sample of hospitals in the United States. We queried the National Electronic Injury Surveillance System for the years 2015-2019 to examine the following variables for sports-related shoulder dislocations: patient age (high school = 13-17 years of age; collegiate = 18-23 years of age), sex, year of admission, and sport type. Using a weighted multiplier, annual incidence rates were estimated based on the US Census estimates and injury rates were compared by sex and age group across the study period. RESULTS: From 2015 to 2019, there were a total of 1329 athletic-related shoulder dislocations that presented to participating EDs. Of these, 698 (52.5%) shoulder dislocations occurred in collegiate athletes, while 631 (47.5%) occurred in high school athletes. Using weighted and adjusted estimates automatically generated by the National Electronic Injury Surveillance System database, this translates to 89,511 total athletic-related shoulder dislocations across the United States (95% confidence interval lower bound 68,224; 95% confidence interval upper bound 110,798). Male athletes demonstrated a higher proportion of shoulder dislocations (87%) than female athletes (13%). The most common sport-specific mechanisms of traumatic shoulder dislocation were basketball (24.1%), football (21%), soccer (7.1%), baseball (7.1%), and weightlifting (3.3%). CONCLUSION: Sports-related shoulder dislocations are frequent in high school-aged and college-aged athletes presenting to the ED. Interventions to reduce incidence of injury should be sport-specific and focus on those participating in contact and noncontact sports. Male athletes have disproportionately higher rates of dislocation. These findings are consistent with the previous epidemiologic trends in the literature that have examined the incidence of shoulder dislocations in this population.

Prevalence of exercise-induced bronchoconstriction and laryngeal obstruction in adolescent athletes.

OBJECTIVES: To study the prevalence of exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (EILO) in adolescent athletes. METHODS: All adolescents (n = 549) attending first year at a sports high school in 2016 and 2017, were invited to answer a questionnaire on respiratory symptoms. The 367 responding participants were divided into two groups based on whether they reported exercise-induced dyspnea (dyspnea group) or not (nondyspnea group). Randomly selected participants in each group were invited to undergo two standardized exercise tests, an EIB test and a continuous laryngoscopy exercise (CLE) test, to investigate EILO. RESULTS: In total, 98 participants completed an EIB test, 75 of whom also completed a CLE test. Positive EIB tests: eight of 41 in the dyspnea group and 16 of 57 in the nondyspnea group. Positive CLE tests: 5 of 34 in the dyspnea group and three of 41 in the nondyspnea group. The estimated prevalence of EIB was 23.1% (95% confidence interval [CI]: 14.5-33.8) and of EILO 8.1% (95% CI: 2.5-18.5) in the whole study population. No differences in prevalence of EIB or EILO were found between the dyspnea and the nondyspnea groups. CONCLUSION: EIB was highly prevalent in this cohort of adolescent athletes. EILO was less prevalent, but represents an important differential diagnosis to EIB. Self-reported exercise-induced dyspnea is a weak indicator for both EIB and EILO and standardized testing should be provided.

Concussion Knowledge, Attitudes, and Self-Reporting Intentions in Youth Athletes.

CONTEXT: Although it has been suggested that developmental and sociological factors play a role in concussion reporting, the empirical evidence related to this is limited. OBJECTIVE: To examine the influences of sex, school level, school location, concussion-reporting history, and socioeconomic status on concussion-related knowledge, attitudes, and reporting intentions among middle school and high school athletes. DESIGN: Cross-sectional study. SETTING: Master students and High School athletes attending pre-participation examinations (PPEs) were asked to complete paper-based surveys. PATIENTS OR OTHER PARTICIPANTS: Overall, 541 athletes representing 18 sports returned fully completed surveys. MAIN OUTCOME MEASURE(S): Outcomes were concussion-related knowledge, perceived seriousness, positive feelings about reporting, and self-reporting intentions. We examined group differences in these outcomes across levels of the explanatory variables of sex, school level (middle school versus high school), school location (urban versus rural), concussion self-reporting history (yes or no), and socioeconomic status (free or reduced-price lunch versus no free or reduced-price lunch) using Wilcoxon rank sum tests. Then we used multivariable ordinal logistic regression models to identify predictors of higher score levels for each outcome. Odds ratio (OR) estimates with 95% confidence intervals (CIs) excluding 1.00 were deemed significant. RESULTS: Odds of higher levels of knowledge were higher in urban versus rural school student-athletes (ORAdjusted = 1.81; 95% CI = 1.03, 3.17), and lower in student-athletes on free or reduced-price lunch versus those not on free or reduced-price lunch (ORAdjusted = 0.52; 95% CI = 0.36, 0.77). Similarly, odds of higher levels of seriousness were lower in male versus female student-athletes (ORAdjusted = 0.48; 95% CI = 0.32, 0.72). Further, odds of higher levels of self-reporting intentions were lower among male versus female student-athletes (ORAdjusted = 0.53; 95% CI = 0.37, 0.75). CONCLUSIONS: Developmental and sociological factors were differentially associated with concussion-related knowledge, attitudes, and self-reporting intentions. These results can inform medical providers, parents, and coaches with regard to context-specific clinical assessments of concussion symptoms.

Compliance With the National Athletic Trainers' Association Inter-Association Task Force Preseason Heat-Acclimatization Guidelines in High School Football.

CONTEXT: In 2009, the National Athletic Trainers' Association Inter-Association Task Force (NATA-IATF) released preseason heat-acclimatization guidelines for gradually acclimatizing high school (HS) athletes to the environment during the first 2 weeks of the preseason and reducing the risk of exertional heat illness. However, researchers who studied the 2011 preseason found a low level of overall compliance. OBJECTIVE: To assess compliance with the NATA-IATF guidelines during the 2017 preseason and compare the findings with 2011 preseason data and between states mandating and not mandating the guidelines. DESIGN: Cross-sectional study. SETTING: Preseason HS football, 2017. PATIENTS OR OTHER PARTICIPANTS: A total of 1023 athletic trainers working with HS football (14.2% response rate). MAIN OUTCOME MEASURE(S): Using a survey, we acquired information from athletic trainers on their HS football programs, including location and compliance with 17 NATA-IATF guidelines during the 2017 football preseason. The outcome measures were full compliance with all 17 NATA-IATF guidelines and compliance with ≥10 NATA-IATF guidelines. Prevalence ratios (PRs) with 95% confidence intervals (CIs) compared findings between (1) the 2017 and 2011 preseasons and (2) states whose HS athletic associations imposed a full or partial or no mandate to follow the NATA-IATF guidelines. RESULTS: Overall, 3.9% reported full compliance with NATA-IATF guidelines; 73.9% complied with ≥10 guidelines. The proportion reporting full compliance was higher in 2017 than in 2011 but not statistically different (3.9% versus 2.5%; PR = 1.54; 95% CI = 0.96, 2.46). However, the proportion reporting compliance with ≥10 guidelines was higher in 2017 (73.9% versus 57.9%; PR = 1.28; 95% CI = 1.20, 1.36). The proportion of respondents reporting their HSs were fully compliant was highest among the with-mandate group (9.4%), followed by the partial-mandate group (4.6%) and the without-mandate group (0.6%). Group differences retained significance when we examined compliance with ≥10 guidelines. CONCLUSIONS: Although full compliance with NATA-IATF guidelines remained low, many HS football programs complied with ≥10 guidelines.
