Study: Los Angeles county's growing youth firearm crisis

Findings revealed at the 2023 Pediatric Academic Societies Meeting

2023-04-28

(Press-News.org) The majority of pediatric firearm injuries in Los Angeles County occur in neighborhoods with limited social, health and educational opportunity, according to a new study exploring incidents from 2010 to 2021. The research will be presented during the Pediatric Academic Societies (PAS) 2023 Meeting taking place April 27-May 1 in Washington, D.C.

Researchers from Children’s Hospital Los Angeles analyzed firearm injuries in 1,383 children under 18 years old using records from the Trauma and Emergency Medicine Information System, which contains data from 15 trauma centers in LA County. Researchers applied the national Childhood Opportunity Index—a measure of factors that contribute to healthy, productive childhood development—to understand how a lack of resources in a child’s environment relates to firearm injury exposure. The Index is administered by Brandeis University.

The study noted the highest rates of pediatric firearm injuries among children were in neighborhoods with very low (62.7%) and low (22.6%) opportunity, compared to areas with moderate (10.5%), high (3.0%) and very high (1.3%) opportunity.

Findings also revealed that approximately 9.7 pediatric firearm injuries per year occurred for every 100,000 children in neighborhoods with a very low level of opportunity, compared to approximately 0.5 incidences for every 100,000 children living in a very high opportunity environment.

“Firearms are the leading cause of deaths in children across the United States and this data speaks volumes that a child’s individual risk is far from equal,” says Abigail Brenner, M.D., pediatric resident physician at Children’s Hospital Los Angeles and presenting author. “We must advocate for children who are disproportionately exposed to firearm injuries and prevent the issue from growing.”

These findings represent a pressing need for targeted advocacy and policy that advances community-level interventions and support, according to the authors.

Abstract: Where You Live Matters: Examining Firearm Injuries and Childhood Opportunity Index in LA County

Presenting Author: Abigail Brenner, M.D.

Organization

Children’s Hospital Los Angeles

Topic

Injury Prevention

Background

Firearm injuries are the leading cause of pediatric death in the United States, and the neighborhood a child lives in influences their exposure to firearms. Childhood opportunity index (COI) is a metric that combines information across three domains: education, health and environment, and social and environment to create a measurement of neighborhood opportunity. Better understanding the relationship between COI and pediatric firearm injury can lead to more focused interventions on a public health and policy level.

Objective

To examine the association between firearm injuries and COI in Los Angeles (LA) County.

Design/Methods

A retrospective cohort study of children < 18 years old from 2010-2021 was performed using the Trauma and Emergency Medicine Information System database, which contains data on firearm injuries evaluated in 15 LA County trauma centers. Population data for each zip code was collected using the Annual Commuter Survey data. Zip code level COI data was collected from Diversity Data Kids. Firearm injury incidence per 100,000 children was determined for each COI using total population < 18 years in LA County in each COI level (very low, low, moderate, high, and very high). Odds ratios based on absolute frequency of firearm injury per COI level and total population per COI level were calculated to determine the association between COI and firearm injury; very high COI was used as the reference group.

Results

The final analysis included 1383 pediatric firearm injury victims, with a median (IQR) age of 16.0 (15.0, 17.0) years. The highest incidence of firearm injury occurred in children from very low COI representing 62.7% of total occurrences. When compared to children from very high COI, children from very low or low COI neighborhoods were at significantly higher risk of experiencing firearm injury (OR 19.89 (12.47-31.71), OR 9.62 [5.98-15.48], respectively) (Table 1).

Conclusion(s)

Children in neighborhoods with very low opportunity are disproportionately exposed to firearm injury. This represents an important area for advocacy and policy in highlighting the need for community level interventions and support when considering pediatric firearm injury.

An international research team led by investigators at Virginia Commonwealth University has identified for the first time markers that may indicate early in life if a person has susceptibility to schizophrenia. The ability to predict the risk of developing schizophrenia later in life may allow early detection and intervention, which the researchers hope can reduce the impact of the disease on individuals, families and communities. Their results have been published in Molecular Psychiatry. Schizophrenia is a serious psychiatric disorder that is most often detected in young adulthood. It ...

Geneticists link phenotype of Balto, famed sled dog, to modern breeds

2023-04-27

ITHACA, N.Y. – A Cornell University-led project has added a new chapter to the story of Balto – the most famous sled dog in history – by using ancient DNA extraction and analysis to reconstruct his phenotype and identify his genetic connections to modern dog breeds. The research reveals Balto’s lineage was genetically healthier and less inbred than modern breeds, with characteristics adapted to the extreme environment of 1920s Alaska. The team’s paper, “Comparative Genomics of Balto, a Famous Historic Dog, Captures Lost Diversity of 1920s Sled Dogs,” published April 27 in Science.
