Youth firearm deaths rose considerably in U.S. states that passed more lenient gun laws after the 2010 US Supreme Court ruling

The use and abuse of children for ideological and political purposes has a long history! Of course, the non-Hispanic black children were most affected. 

Of course, the usual suspects immediately reported about this most likely flawed study!

It appears, the results of the study were preconceived. It was only a matter of designing the study in such a way that it produces the desired results.

What is missing or dubious:
  1. No breakdown of cause of deaths provided. Not deaths by year and state data provided etc.
  2. What is excess deaths please? This term smells very much of propaganda!
  3. No discussion how population changes (like increases or decreases) may have affected the results.

"Youth firearm deaths rose considerably in U.S. states that passed more lenient gun laws after a 2010 Supreme Court ruling limited local governments’ capacity to limit gun ownership, per a new study in JAMA Pediatrics; in states with stricter laws, gun deaths held steady or even fell—and dipped significantly in four: California, Maryland, New York, and Rhode Island."

"Child gun deaths have surged since a 2010 Supreme Court ruling led some state and local governments to relax their firearm laws, according to a new Mass General Brigham study. ..."

From the key points and abstract:
"Key Points
  • Question
    Did states enacting permissive firearm laws after 2010—when McDonald v Chicago was decided by the US Supreme Court—subsequently experience higher rates of pediatric firearm mortality?
  • Findings
    Excess mortality analysis found that a group of states with the most permissive firearm laws after 2010 experienced more than 6029 firearm deaths in children and adolescents aged 0 to 17 years between 2011 and 2023 and 1424 excess firearm deaths in a group of states with permissive laws. In the most permissive states, the largest increase occurred in the non-Hispanic Black pediatric population; among all states, 4 states had statistical decreases in pediatric firearm mortality during the study period, all of which were in states with strict firearm policies.
  • Meaning
    These results demonstrate that permissive firearm laws contributed to thousands of excess firearm deaths among children living in states with permissive policies; future work should focus on determining which types of laws conferred the most harm and which offered the most protection.

Abstract
Importance  Firearms are the leading cause of death in US children and adolescents, but little is known about whether the overall legal landscape was associated with excess mortality after a landmark US Supreme Court decision in 2010.

Objective  To measure excess mortality due to firearms among US children aged 0 to 17 years after the McDonald v Chicago US Supreme Court decision (2010).

Design, Setting, and Participants
An excess mortality analysis was conducted using the US Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research (WONDER) database before and after McDonald v Chicago, the landmark 2010 US Supreme Court decision on firearms regulation. States were divided into 3 groups based on legal actions taken before and since 2010, most permissive, permissive, and strict. Firearm mortality trends before (1999-2010) and after (2011-2023) were determined and compared across the 3 groups for all intents and by intent (homicide and suicide). Subgroup analysis by observed race and ethnicity was conducted. For each US state, pre–and post–McDonald v Chicago all-intent pediatric firearm mortality incident rates were compared. These data were analyzed January 2011 through December 2023.
Exposure  The pre– and post–McDonald v Chicago legal landscape.
Main Outcomes and Measures  Excess mortality during the post–McDonald v Chicago period.

Results
During the post–McDonald v Chicago period (2011-2023), there were 6029 excess firearm deaths (incidence rate [IR], 158.6 per million population; 95% CI, 154.8-162.5) in the most permissive group.
In the permissive group, there were 1424 excess firearm deaths (IR, 107.5 per million person-years; 95% CI, 103.8-111.3).
In the strict group, there were −55 excess firearm deaths (IR, −2.5 per million person-years; 95% CI, −5.8 to 0.8). 

Non-Hispanic Black populations were had the largest increase in firearm mortality in the most permissive and permissive state groupings.
Four states (California, Maryland, New York, and Rhode Island) had decreased pediatric firearm mortality after McDonald v Chicago, all of which were in the strict firearms law group.

Conclusion
States in the most permissive and permissive firearm law categories experienced greater pediatric firearm mortality during the post–McDonald v Chicago era. Future work should focus on determining which types of laws conferred the most harm and which offered the most protection."
