Epidemiology of United States high school sports-related fractures, 2008-09 to 2010-11.

ABSTRACT: High school athletes sustain millions of injuries annually, many of which are fractures. Fractures can severely affect athletes physically, emotionally, and financially and should be targeted with focused prevention methods.Patterns and primary mechanisms of fractures differ by sport and gender.Descriptive epidemiology study.High school sports-related injury data were collected from academic years 2008-09 to 2010-11 for 18 sports and from 2009-10 to 2010-11 for 2 additional sports. We used linear regression to describe annual fracture rate trends and calculated fractures rates, rate ratios (RRs), and injury proportion ratios (IPRs).From 2008-09 to 2010-11, certified athletic trainers reported a total of 21,251 injuries during 11,544,455 athlete exposures (AEs), of which 2103 (9.9%) were fractures, with an overall rate of 1.82 fractures per 10,000 AEs. Fracture rates were highest in football (4.37 per 10,000 AE), boys' ice hockey (3.08), and boys' lacrosse (2.59). Boys sustained 79.1% of all fractures, and the overall rates of fractures were greater in boys' sports than in girls' sports for competition (RR, 2.82; 95% CI, 2.45-3.24) and practice (RR, 2.43; 95% CI, 2.07-2.86). The most commonly fractured body sites were the hand/finger (32.1%), lower leg (10.1%), and wrist (9.5%). Overall, 17.2% of fractures required surgery, which was higher than for all other injuries combined (IPR, 3.14; 95% CI, 2.81-3.52). The most common mechanism of fracture involved contact with another player (45.5%). Using linear regression, we found the proportion of all injuries that were fractures was inversely correlated with the athlete's age (P = .02) but was not correlated with the athletes' age- and gender-adjusted body mass index.Fractures are a significant problem for high school athletes. Targeted preventive interventions should be implemented to reduce the burdens these injuries cause the athletes.

Project description:BACKGROUND:There exists little nationwide data regarding fracture and dislocation patterns across a wide variety of sporting activities for all ages and sexes. HYPOTHESIS:Participant demographics (age and sex) will vary with regard to fracture and joint dislocation sustained during sport-related activities. STUDY DESIGN:Descriptive epidemiology study. LEVEL OF EVIDENCE:Level 3. METHODS:The National Electronic Injury Surveillance System All Injury Program data 2005 through 2013 were accessed; 18 common sports and recreational activities in the United States were selected. Statistical software was used to calculate the numbers of fractures and dislocations, and incidence was calculated using US Census Bureau data. Multivariate logistic regression analysis determined the odds ratios (ORs) for the occurrence of a fracture or dislocation. RESULTS:A fracture occurred in 20.6% and a joint dislocation in 3.6% of the emergency department visits for sports-related injuries; annual emergency department visit incidence was 1.51 for fractures and 0.27 for dislocations (per 1000 people). Most of the fractures occurred in football (22.5%). The OR for fracture was highest for inline skating (OR, 6.03), males (OR, 1.21), Asians, whites, and Amerindians compared with blacks (OR, 1.46, 1.25, and 1.18, respectively), and those older than 84 years (OR, 4.77). Most of the dislocations occurred in basketball (25.7%). The OR for dislocation was highest in gymnastics (OR, 4.08), males (OR, 1.50), Asians (OR, 1.75), and in those aged 20 to 24 years (OR, 9.04). The most common fracture involved the finger, and the most common dislocation involved the shoulder. CONCLUSION:Inline skating had the greatest risk for fracture, and gymnastics had the greatest risk for joint dislocation. CLINICAL RELEVANCE:This comprehensive study of the risks of sustaining a fracture or dislocation from common sports activities across all age groups can aid sports health providers in a better understanding of those sports at high risk and be proactive in prevention mechanisms (protective gear, body training).

Project description:ImportanceGroup B Streptococcus (GBS) is an important cause of invasive bacterial disease. Previous studies have shown a substantial and increasing burden of GBS infections among nonpregnant adults, particularly older adults and those with underlying medical conditions.ObjectiveTo update trends of invasive GBS disease among US adults using population-based surveillance data.Design, setting, and participantsIn this population-based surveillance study, a case was defined as isolation of GBS from a sterile site between January 1, 2008, and December 31, 2016. Demographic and clinical data were abstracted from medical records. Rates were calculated using US Census data. Antimicrobial susceptibility testing and serotyping were performed on a subset of isolates. Case patients were residents of 1 of 10 catchment areas of the Active Bacterial Core surveillance (ABCs) network, representing approximately 11.5% of the US adult population. Patients were included in the study if they were nonpregnant, were 18 years or older, were residents of an ABCs catchment site, and had a positive GBS culture from a normally sterile body site.Main outcomes and measuresTrends in GBS cases overall and by demographic characteristics (sex, age, and race), underlying clinical conditions of patients, and isolate characteristics are described.ResultsThe ABCs network detected 21 250 patients with invasive GBS among nonpregnant adults from 2008 through 2016. The GBS incidence in this population increased from 8.1 cases per 100 000 population in 2008 to 10.9 in 2016 (P = .002 for trend). There were 3146 cases reported in 2016 (59% male; median age, 64 years; age range, 18-103 years). The GBS incidence was higher among men than women and among blacks than whites and increased with age. Projected to the US population, an estimated 27 729 cases of invasive disease and 1541 deaths occurred in the United States in 2016. Ninety-five percent of cases in 2016 occurred in someone with at least 1 underlying condition, most commonly obesity (53.9%) and diabetes (53.4%). Resistance to clindamycin increased from 37.0% of isolates in 2011 to 43.2% in 2016 (P = .02). Serotypes Ia, Ib, II, III, and V accounted for 86.4% of isolates in 2016; serotype IV increased from 4.7% in 2008 to 11.3% in 2016 (P < .001 for trend).Conclusions and relevanceThe public health burden of invasive GBS disease among nonpregnant adults is substantial and continues to increase. Chronic diseases, such as obesity and diabetes, may contribute.
