Synthetic cannabinoids have gained popularity over the past decade, especially among young adults, due to sharing similar psychoactive properties with Tetrahydrocannabinol (THC). A limited number of studies have examined synthetic cannabinoid use among college students but none have examined use exclusively by collegiate student-athletes. The objective of this study was to examine synthetic cannabinoid use among collegiate student-athletes. In the spring of 2013, 3,276 freshmen and transfer coll ...[more]

Project description:ContextMandated concussion education has aimed to improve student-athlete knowledge; however, some collegiate student-athletes continue to not disclose concussion. Concussion knowledge may not be the only factor influencing reporting, as student-athlete sex, sport, and pressure from external stakeholders (eg, coaches, teammates, fans, parents or family) have all been documented as influencing collegiate concussion-reporting behavior.ObjectiveTo examine factors associated with concussion nondisclosure in collegiate student-athletes.DesignCross-sectional study.SettingFour National Collegiate Athletic Association Division I and two Division II universities.Patients or other participantsA total of 1125 collegiate student-athletes completed the survey, and 741 provided viable responses and were included for data analysis.Main outcome measure(s)We used a 10- to 15-minute electronic or paper-and-pencil survey that asked about personal and sport demographics, diagnosed concussions and nondisclosed concussion history, concussion knowledge, and level of agreement regarding pressure to play after a head impact experienced during collegiate sport participation. Significant univariable factors were entered into a multivariable logistic regression analysis.ResultsSex (P = .005), sport-risk type (P < .001), diagnosed concussion history (P < .001), concussion knowledge (P = .017), and pressure from coaches (P < .001), teammates (P < .001), fans (P = .024), and parents or family (P = .003) were factors associated with concussion nondisclosure in individual univariable logistic regressions. After we conducted multivariable analyses, male sex (P = .001), high concussion-risk sport participation (P = .048), diagnosed concussion history (P < .001), increased concussion knowledge (P = .013), and experiencing pressure from coaches to continue playing after sustaining a hit to the head (P = .002) were factors associated with concussion nondisclosure in collegiate student-athletes.ConclusionsOur results suggest that concussion-education programs should go beyond the identification of signs and symptoms to include the dangers of continuing to play, long-term consequences, and transparency about concussion protocols. Comprehensive concussion-education programs should involve coaches and athletes to improve the reporting culture.

Project description:ObjectiveTo describe variability in concussion biomarker concentrations collected from serum in a sample of healthy collegiate athletes, as well as report reliability metrics in a subsample of female athletes.MethodsIn this observational cohort study, β-amyloid peptide 42 (Aβ42), total tau, S100 calcium binding protein B (S100B), ubiquitin carboxy-terminal hydrolyzing enzyme L1 (UCH-L1), glial fibrillary acidic protein, microtubule associated protein 2, and 2',3'-cyclic-nucleotide 3'-phosphodiesterase (CNPase) serum concentrations were measured in 415 (61% male, 40% white, aged 19.0 ± 1.2 years) nonconcussed collegiate athletes without recent exposure to head impacts. Standardized normative distributions are reported for each biomarker. We evaluated main effects (analyses of variance) of sex and race, reporting demographic-specific normative metrics when appropriate. In a subset of 31 female participants, test-retest reliability (Pearson r) and reliable change indices (80%, 90%, and 95% confidence intervals) across a 6- to 12-month interval are reported for Aβ42, total tau, S100B, and UCH-L1.ResultsMales exhibited higher UCH-L1 (p < 0.001, Cohen d = 0.75) and S100B (p < 0.001, d = 0.56) than females, while females had higher CNPase (p < 0.001, d = 0.43). Regarding race, black participants had higher baseline levels of UCH-L1 (p < 0.001, d = 0.61) and S100B (p < 0.001, d = 1.1) than white participants. Conversely, white participants had higher baseline levels of Aβ42 (p = 0.005, d = 0.28) and CNPase (p < 0.001, d = 0.46). Test-retest reliability was generally poor, ranging from -0.02 to 0.40, and Aβ42 significantly increased from time 1 to time 2.ConclusionHealthy collegiate athletes express concussion-related serum biomarkers in variable concentrations. Accounting for demographic factors such as sex and race is essential. Evidence suggested poor reliability for serum biomarkers; however, understanding how other factors influence biomarker expression, as well as knowledge of reliable change metrics, may improve clinical interpretation and future study designs.

Project description:Research has shown that exposure to a concussion definition (CD) increases self-reported concussion history (SRCH) immediately, however, no research has been performed that examines the effects of exposure to a CD on SRCH over time. Collegiate recreational student-athletes (RSAs) have limited access to monitoring and supervision by medical staff. As such, recognition of concussion symptoms and need for medical management oftentimes falls upon the RSA. The purpose of this study was to assess the effect of a novel questionnaire on the SRCH of RSAs. A two-part questionnaire was sent to RSAs participating is sports with a greater than average risk of concussion at a university in Arizona. Data from 171 RSAs were analyzed to assess the change in RSAs' suspected concussion estimates pre- and post-exposure to a CD and concussion symptom worksheet, as well as over the short-term (2.5 months). Approximately one-third of RSAs reported an increase in suspected concussion estimates immediately following exposure to the questionnaire, but the change was not maintained over the short-term. The results suggest that a single exposure to a CD is ineffective at increasing short-term SRCH estimates.

Project description:BackgroundAlthough eye injuries constitute a small percentage of high school and college sports injuries, they have the potential to be permanently debilitating.HypothesisEye injury rates will vary by sport, sex, and between the high school and college age groups.Study designDescriptive epidemiology study.Level of evidenceLevel 3.MethodsData from eye injury reports in high school and college athletes were obtained from the National High School Sports-Related Injury Surveillance System, High School Reporting Information Online (HS RIO) database over a 10-year span (2005-2006 through 2014-2015 school years) and the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) over an 11-year span (2004-2005 through 2014-2015 school years). Injury rates per 100,000 athlete-exposures (AEs), injury rate ratios (RRs), and 95% CIs were calculated. Distributions of eye injuries by diagnosis, mechanism, time loss, and surgery needs were also examined.ResultsA total of 237 and 273 eye injuries were reported in the HS RIO and the NCAA ISP databases, respectively. The sports with the highest eye injury rates (per 100,000 AEs) for combined high school and college athletes were women's basketball (2.36), women's field hockey (2.35), men's basketball (2.31), and men's wrestling (2.07). Overall eye injury rates at the high school and college levels were 0.68 and 1.84 per 100,000 AEs, respectively. Eye injury rates were higher in competition than practice in high school (RR, 3.47; 95% CI, 2.69-4.48) and college (RR, 3.13; 95% CI, 2.45-3.99). Most injuries were contusions (high school, 35.9%; college, 33.3%) and due to contact (high school, 89.9%; college, 86.4%). Only a small percentage of injuries resulted in time loss over 21 days (high school, 4.2%; college, 3.0%).ConclusionEye injury rates and patterns vary by sport, sex, and between the high school and college age groups. Although severe injuries do occur, most eye injuries sustained by high school and college athletes are minor, with limited time loss and full recovery.Clinical relevanceAdditional focus needs to be placed on preventing eye injuries at the collegiate level in women's and men's basketball, women's field hockey, and men's wrestling.

Project description:BACKGROUND:Timely removal from activity after concussion symptoms remains problematic despite heightened awareness. Previous studies indicated potential adverse effects of continuing to participate in physical activity immediately after sustaining a concussion. Hypothesis/Purpose: The purpose was to determine the effect of timing of removal from play after concussion on clinical outcomes. It was hypothesized that immediate removal from activity after sport-related concussion (SRC) would be associated with less time missed from sport, a shorter symptomatic period, and better outcomes on acute clinical measures. STUDY DESIGN:Cohort study; Level of evidence, 3. METHODS:Data were reported from the National Collegiate Athletic Association and Department of Defense Grand Alliance: Concussion Awareness, Research, and Education (CARE) Consortium. Participants with 506 diagnosed SRCs from 18 sports and 25 institutions and military service academies were analyzed and classified as either immediate removal from activity (I-RFA) or delayed removal from activity (D-RFA). Outcomes of interest included time missed from sport attributed to their SRC, symptom duration, and clinical assessment scores. RESULTS:There were 322 participants (63.6%) characterized as D-RFA. I-RFA status was associated with significantly less time missed from sport ( R2 change = .022-.024, P < .001 to P = .001) and shorter symptom duration ( R2 change = .044-.046, P < .001 [all imputations]) while controlling for other SRC recovery modifiers. These athletes missed approximately 3 fewer days from sport participation. I-RFA athletes had significantly less severe acute SRC symptoms and were at lower risk of recovery taking ?14 days (relative risk = .614, P < .001, small-medium effect size) and ?21 days (relative risk = .534, P = .010, small effect size). CONCLUSION:I-RFA is a protective factor associated with less severe acute symptoms and shorter recovery after SRC. Conveying this message to athletes, coaches, and others involved in the care of athletes may promote timely injury reporting.

Project description:BackgroundThere is a dearth of research on the current health of former collegiate athletes.PurposeTo examine the current health and related correlates in a cohort of former collegiate athletes who played in a diverse range of men's and women's sports with various levels of contact.Study designCross-sectional study; Level of evidence, 3.MethodsFormer collegiate athletes (N = 3657) were asked to complete an online questionnaire addressing sports history, medical history, and demographics. The questionnaire also included the Veterans RAND 12-Item Health Survey (VR-12), which yielded 2 composite scores for physical (PCS) and mental (MCS) health. The VR-12 PCS and MCS scores were compared with published US normative data using t tests and analyses of variance.ResultsMean PCS and MCS scores of the 797 respondents with complete data (21.9% of target sample; average, 14.5 years since last played collegiate sport) were 53.0 ± 6.1 and 51.7 ± 9.4, respectively. When stratified by age and sex, PCS and MCS scores were similar to normative scores in the United States. Lower PCS scores were associated with sustaining ≥3 concussions, playing in collision sports during college, and sustaining a career-ending injury (all, P < .001). No association was found between concussion and MCS scores (P = .06). Among former collegiate athletes, prevalent medical conditions included anxiety (16.2%), hypercholesterolemia/high cholesterol (10.6%), and depression (10.4%). Additionally, 5.8% screened positive for alcohol dependence, and 5.8% screened positive for disordered eating (eg, binge eating, purging). These findings were more prevalent than those reported by the World Health Organization as representative of the US population. Conversely, there was a lower prevalence of depression, bipolar disorders, and attention deficit disorder, with or without hyperactivity (ADD/ADHD), than in the World Health Organization US population data sample.ConclusionFormer collegiate athletes appear similar to the general US population on many aspects of mental and physical health. However, observed health deficits associated with previous sports injuries warrant ongoing monitoring of the health and well-being of former collegiate athletes.

Project description:BackgroundMenstrual irregularity (MI) is common in female athletes and is a component of the Female Athlete Triad (Triad). Many athletes with the Triad are started on hormonal contraceptives (HC) for MI, but this interferes with the ability to monitor menstrual cycle regularity and can mask other causes of MI. There are limited studies investigating the relationship between MI, HC use, and injury in female collegiate athletes.ObjectiveTo examine the prevalence of and relationship between HC use, MI, and bone stress injuries in female collegiate athletes in the United States.DesignCross-sectional study.SettingOnline survey.Participants1020 U.S. female collegiate athletes (age ≥ 18 years).Methods or interventionsAssessment of risk factors for menstrual irregularity and bone stress injuries was conducted via a one-time survey.Main outcome measuresHC use, MI, history of stress fractures.ResultsCurrent HC use prevalence was 65% (95% confidence interval [CI], 61.9%, 67.8%). Of all athletes, 47% reported past MI. Of the athletes who were not currently using HCs, 32% had current MI. Compared with athletes without past MI, more athletes with past MI reported current HC use (73% vs. 57%) and indicated menstrual cycle consistency as the primary reason for use (24% vs. 4%) (P < .001). Additionally, 25% of athletes reported a history of stress fractures, which was associated with lean/aesthetic sports participation (odds ratio [95% CI]: 1.9 [1.4, 2.5]; P < .001) and less oral contraceptive pill (OCP) use (0.7 [0.5, 1.0]; P = .043). Compared with OCPs, injectable HCs were associated with greater odds of a history of stress fractures (4.5[1.6, 12.3]; P = .004).ConclusionsHC use was prevalent among this cohort of female collegiate athletes, and almost half of the athletes reported past MI. A goal of menstrual cycle regularity was cited by 24% of athletes as a primary reason to use HCs, which shows that more athlete education is needed to avoid masking MI and the Triad with HCs. Further studies elucidating the relationship between HC use, MI, and sports-related injury are warranted.

Project description:Dietary supplements, sports foods, and ergogenic supplements are consumed to increase performance, recovery, and health, but risk contamination with illegal substances. Third-party testing programs may assist in regulating the purity and safety of supplements, yet athletes' attitudes and use of such programs are not widely reported. This study examined nutritional supplement knowledge, attitudes, and use, as well as the purchase of third-party tested supplements among university student-athletes (N = 138). Knowledge of nutritional supplements yielded a median and (IQR) score of 25% (17 to 42%). Sixteen percent of student-athletes said they were knowledgeable about supplements and their effects, p < 0.001. All athletes stated they used a dietary supplement or sports food at least once within the last 12 months, and 77% consumed at least one "claimed to be" ergogenic supplement. Sixty-six percent of student-athletes purchased nutritional supplements not provided by the athletic department. Females athletes were more likely to consume a combination of vitamins and single minerals, a larger variety of sports foods, exotic berries, herbs, maca root powder, ribose, ephedra, colostrum, and hydroxy-methyl-buterate (HMB) than males. Over 90% believed it was essential to know if a supplement was third-party tested. However, only 57% stated the supplements bought were third-party tested. No sex differences were found for nutritional supplement knowledge, attitudes, and use of third-party testing programs. Our results indicate a need to improve student-athletes' attitudes toward and knowledge of nutritional supplements, and the initiation of programs to assist in the choosing and consuming of third-party tested supplements.

Project description:BackgroundConcussions have been associated with elevated musculoskeletal injury risk; however, the influence of unreported and unrecognized concussions has not been investigated.HypothesisThe purpose of this study was to examine the association between concussion and lower extremity musculoskeletal injury rates across a diverse array of sports among collegiate student-athletes at the conclusion of their athletic career. The hypothesis was that there will be a positive association between athletes who reported a history of concussions and higher rates of lower extremity injuries.Study designCross-sectional study.Level of evidenceLevel 3.MethodsStudent-athletes (N = 335; 62.1% women; mean age, 21.2 ± 1.4 years) from 13 sports completed a reliable injury history questionnaire. Respondents indicated the total number of reported, unreported, and potentially unrecognized concussions as well as lower extremity injuries including ankle sprains, knee injuries, and muscle strains. Chi-square analyses were performed to identify the association between concussion and lower extremity injuries.ResultsThere were significant associations between concussion and lateral ankle sprain ( P = 0.012), knee injury ( P = 0.002), and lower extremity muscle strain ( P = 0.031). There were also significant associations between reported concussions and knee injury ( P = 0.003), unreported concussions and knee injury ( P = 0.002), and unrecognized concussions and lateral ankle sprain ( P = 0.001) and lower extremity muscle strains ( P = 0.006), with odds ratios ranging from 1.6 to 2.9.ConclusionThere was a positive association between concussion history and lower extremity injuries (odds ratios, 1.6-2.9 elevated risk) among student-athletes at the conclusion of their intercollegiate athletic careers.Clinical relevanceClinicians should be aware of these elevated risks when making return-to-participation decisions and should incorporate injury prevention protocols.

Project description:Background Ventricular-arterial (VA) coupling is defined as the ratio between arterial elastance (EA) and left ventricular elastance (ELV). VA uncoupling, as occurs in hypertensive heart disease, is associated with adverse outcomes. This study sought to determine the relationship between American football (AF)-associated hypertension and VA uncoupling. Methods and Results This was a multicenter, longitudinal, and repeated measures observational study of collegiate AF athletes across 3 years of AF participation. Of 200 freshman athletes initially enrolled, 142 (67 Black [47%]/75 White [53%], 58 linemen [41%]/84 nonlinemen [59%]) were prospectively studied with echocardiography and applanation tonometry. Primary echocardiographic VA coupling outcome measures were EA/ELV and ΔEA/ELV, with increased EA/ELV indicating VA uncoupling. Adjusting for race and player position, AF athletes demonstrated increased EA/ELV (mean [95% CI]Δ, 0.10 [0.04-0.15]; P=0.001) and systolic blood pressure (SBP) (mean [95% CI]Δ, 11.4 [8.3-14.5] mm Hg, P<0.001) over their collegiate AF careers. In combination with longitudinal VA uncoupling, hypertension prevalence (including both stage 1 and 2) increased from 54% at baseline to 77% (44% stage 2) at the end of the study period (P<0.001). In multivariable mixed-effects linear regression analysis, higher SBP (β=0.021, P=0.02), lower E' (β=-0.010, P=0.03), and worse global longitudinal strain (β=0.036, P<0.001) were associated with higher EA/ELV. Increased SBP (ΔSBP, β=0.029, P=0.02) and worsened global longitudinal strain (Δglobal longitudinal strain, β=0.045, P<0.001) also predicted increased ΔEA/ELV. Conclusions VA uncoupling is associated with pathologically increased SBP and subclinical impairments in left ventricular systolic function in collegiate AF athletes, indicating a key mechanism underlying maladaptive cardiovascular phenotypes observed in this population. Future studies analyzing whether targeted clinical interventions improve VA coupling and health outcomes are warranted.
