Is Cumulative Load Associated with Injuries in Youth Team Sport? A Systematic Review.

BACKGROUND: High cumulative external and internal load may predispose athletes to increased risk for injury across a variety of sports, competition levels, and age groups. However, evidence of an association between cumulative load and injury in youth sport remains inconclusive. The objective of this study was to determine the current evidence for cumulative load and injury risk relationships in youth team sport through a systematic review of the existing literature. METHODS: A systematic review of the literature was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Literature searches were conducted in PubMed, Web of Science, SCOPUS, and CINAHL for relevant articles published between January 2010 and April 2021. The authors conducted independent review and quality assessment of the eligible studies. Eleven articles evaluating youth (less than 18 years old) team sport were included for qualitative synthesis. RESULTS: Fifty-nine percent (n = 39/66) of the relationships assessed revealed an association between cumulative load and injury across the team sports studied, including the presence of load-injury associations in 84% (n = 16/19) of assessments in youth soccer. Of those relationships where an association was present, 79% (n = 31/39) were positive associations between cumulative load and injury. Risk of bias assessment scores ranged from three to six out of seven possible (median = 5) for cohort studies and from four to seven out of 10 possible (median = 5.5) for cross-sectional studies. CONCLUSIONS: There is some evidence for a positive association between load and injury in youth team sport. Youth soccer was the most studied team sport, and a substantial number of positive load-injury associations were reported. Current evidence lacks consistency in the measures and metrics used in defining load-injury relationships. Trial Registration PRISMA ID - CRD42020203622.

We Asked, They Told Us: The Use of an Electronic Survey to Address Parental Health Concerns for Children.

Population health includes medical conditions and social determinants of health, and it can be measured through community health needs assessments (CHNAs). A pediatric hospital utilized a survey to ask parents to rank different health topics based on the severity they present to children in the St. Louis Metropolitan for 2 installments of a CHNA (2016 and 2019). Between November 2015 and April 2016, 1156 parents and, between May 2018 and September 2018, 1022 parents responded to the Parent Health Concerns Survey. Respondents were most likely to be 25 to 44 years old, white, educated, have an income of at least $60 000, and work-related insurance. The top needs identified in 2016 and 2018 were lack of exercise and bullying, respectively. Depression saw the largest increase. Emerging topics in 2018 include tobacco/smoking, depression, and health insurance access. Our findings suggests that pediatricians should be prepared to address concerns across a wide variety of topics.

Safe summers: Adapting evidence-based injury prevention into a summer curriculum.

BACKGROUND: Unintentional injury is the leading cause of death for those aged 0 years to 19 years. St. Louis Children's Hospital created Safety Land, a comprehensive injury prevention intervention which is provided during summer months. This program uses a life-size board game to teach safety education to children in ages 5 years to 11 years. The purpose of this study was to evaluate the effect of Safety Land on safety knowledge in children that participated in the intervention. METHODS: St. Louis Children's Hospital identified ZIP codes with the highest use of the emergency room for injury. Daycares and summer camps within these ZIP codes were targeted for the Safety Land intervention. A multiple choice pretest and posttest survey was designed to measure knowledge change within program participants. Students were selected for testing based on site availably. Within these sites, a convenience sample of children was selected for pretesting and posttesting. Safety Land staff conducted the pretest a week before the intervention, and the posttest was administered the week after the intervention. A total knowledge score was calculated to determine overall knowledge change. Descriptive statistics and independent-samples t tests were conducted to determine statistical significance of change in knowledge (p < 0.05) for each question. RESULTS: Between May 2014 and August 2016, 3,866 children participated in Safety Land. A total of 310 children completed the pretest and 274 completed the posttest. Mean test scores increased from 66.7% to 85.1% and independent-samples t test of the total knowledge score was significant (p < 0.05) between pretest and posttest values. CONCLUSION: Findings suggest that this intervention is effective in increasing the knowledge of safety behaviors for children receiving the curriculum during the summer months. Further research should focus on long-term behavior changes in these youth.

Racial/Ethnic Differences in Pediatric Brain Tumor Diagnoses in Patients with Neurofibromatosis Type 1.

OBJECTIVE: To evaluate evidence for differences in pediatric brain tumor diagnoses by race and ethnicity using a cross-sectional study design in individuals with neurofibromatosis type 1 (NF1). STUDY DESIGN: Subjects with NF1 were ascertained from the NF1 Patient Registry Initiative and through a clinical record database of patients at a large academic medical center. Logistic regression was employed to calculate ORs and 95% CIs to analyze differences in the odds of brain tumor diagnosis by race (White, Black, Asian, other/unknown) and ethnic (Hispanic vs non-Hispanic) groups. RESULTS: Data from a total of 1546, 629, and 2038 individuals who were ascertained from the NF1 Patient Registry Initiative, clinical records, and pooled datasets were analyzed, respectively. After adjusting for birth year, we observed a significantly reduced odds of brain tumor diagnoses in individuals self-identified or clinically reported as Black (OR = 0.13, 95% CI 0.05-0.31), Asian (OR = 0.15, 95% CI 0.04-0.64), and other/unknown (OR = 0.61, 95% CI 0.41-0.93) race compared with those with reported as White race. There was no significant difference in the odds of pediatric brain tumor diagnosis by Hispanic ethnicity. CONCLUSIONS: Consistent with prior smaller studies, these data suggest that pediatric brain tumor diagnoses vary by race in individuals with NF1. Reasons underlying observed differences by race warrant further investigation.
