In the United States, the leading causes of death among children vary significantly by age group. Unlike adults – where chronic disease dominates – child mortality is driven primarily by injuries, with medical conditions playing a larger role in infancy.
- Infants (Under 1 year old) – majority of child deaths occur in the first year of life.
- Congenital anomalies (birth defects) – structural or genetic conditions affecting the heart, brain, lungs, or other organs.
- Preterm birth and low birth weight complications – prematurity is one of the strongest predictors of infant mortality.
- Sudden Infant Death Syndrome (SIDS) – unexplained death during sleep.
- Maternal pregnancy complications.
- “Accidental suffocation and strangulation in bed.
These causes are largely medical and perinatal rather than behavioral.
- Children (Ages 1-4) – after infancy, injury becomes the dominant cause of death.
- Unintentional injuries – drowning; motor vehicle crashes; fire/burns; and poisoning.
- Homicide
- Cancer – leukemia and brain tumors.
- Congenital conditions (ongoing effects).
- Children and Adolescents (Ages 5-14) – injury remains the primary driver.
- Unintentional injuries – motor vehicle crashes; drowning; and accidental firearm injury.
- Cancer – brain and central nervous system tumors; leukemia.
- Homicide
- Suicide (rising concern in older children within this group).
- Adolescents (Ages 15-19) – for older teens, the pattern shifts further toward violence and self-harm.
- Unintentional injuries – motor vehicle crashes; drug overdoses (increasing in recent years).
- Homicide – firearms are a major factor in this category.
- Suicide – often linked to depression, anxiety, bullying, substance use, and social stressors.
Cancer remains present but is no longer among the top causes for this age group.
In Summary: Overall Patterns – across childhood (ages 1-19 combined), reveal the following:
- Injury – not disease – is the main cause of death after infancy.
- Violence and self-harm are major drivers in adolescence.
- Cancer is the leading disease-related cause of death in children.
- Infant mortality remains largely medical and linked to prematurity and congenital conditions.

Jen Christensen, of CNN Health, published on 7-7-25, “American children’s health has declined profoundly over the past few decades, a new study shows, and the issues are so serious that children in the United States are dying at a much higher rate than those is similar high-income countries.”
Dr. Chris Forrest, co-author of a study published in the journal JAMA, “What’s particularly frustrating is that the bulk of the health problems are avoidable. There isn’t a genetic defect unique to American children and it’s not about socioeconomics within the United States.”
Dr. Forrest went on to comment, “Kids in this country are really suffering.”
From 2007 to 2022, children aged 1 to 19 were 1.8 times more likely to die than children in other high-income countries. The biggest disparities were in deaths from gun violence and traffic accidents – kids in the U.S. were 15 times more likely than their counterparts in other countries to die by firearms and more than twice as likely to die in motor vehicle crashes.
But U.S. children are also sicker because of chronic conditions, Forrest said, and that’s a newer phenomenon. In the 1990s, when he started taking care of children, he said he hardly ever saw one with a chronic condition. Today, nearly half of children are getting medical care for a chronic health problem.
Researchers, who analyzed hundreds of millions of health records from five nationally representative surveys and electronic health records from 10 pediatric health systems, found that a child in 2023 was 15% to 20% more likely to have a chronic condition than a child in 2011.
Rates of mental health problems such as depression, anxiety and loneliness increased, as did rates of autism, behavioral conduct problems, developmental delays, speech language disorders and attention-deficit hyperactivity disorders.
Rates of physical issues also increased significantly, including problems with obesity, difficulties with limitations in activity, problems with sleeping and early menstruation. A period before age 12 is associated with immediate health problems including type 2 diabetes, but in the long term, it may also raise the risk of heart and blood pressure problems.
A recent federal government report from the Make America Healthy Again Commission said that chronic disease had made children “the sickest generation in American history.” That report blamed ultra processed food, exposure to chemicals in the environment, persuasive technology use and the overprescription of medicine.
Dr. Forrest believes the nation’s entire approach toward caring for children needs to change.
“Our kids are being raised in a very toxic environment, and it’s not just the chemicals. It’s not just the food and the iPhones. It’s much broader. It’s much deeper. It’s what we call the development ecosystem, and it makes it very challenging to change it,” Forrest said. “That’s a hard answer for people who want a pithy message that tells them how to fix the issues. It’s about where they’re growing up, where they’re going to school, they’re playing, where their families live, their neighborhoods, and it’s not just one population. It’s the whole nation that needs help.”

A personal perspective from the author of this BLOG:
For much of the 20th century, physical education (PE) was considered a core part of American schooling – not an elective, but a requirement alongside math, reading, and science. From the 1950s through the 1980s, most public schools required students to participate in structured physical activity multiple times per week. This emphasis was reinforced nationally after concerns about youth fitness during the Cold War era.
In 1956, President Eisenhower established the President’s Council on Youth Fitness – later the President’s Council on Physical Fitness and Sports, which encouraged schools to adopt standardized fitness testing and regular PE programs.
Typical features of PE programs in past decades included:
- Mandatory participation for nearly all students.
- Daily or near-daily classes in many districts.
- Fitness testing (pull-ups, sit-ups, mile runs).
- Team sports (basketball, baseball, football, volleyball).
- Individual fitness activities (track, calisthenics, gymnastics).
- Outdoor recess as a complement to formal PE.
- After-school sports participation is a common expectation.
In addition to structured classes, children were generally more physically active outside school. Walking or biking to school, unstructured neighborhood play, and limited screen time contributed to higher daily movement levels compared to today.
Beginning in the 1990s and accelerating after the early 2000s, several factors reduced PE time:
- Budget cuts affecting PE staffing.
- Increased screen time.
- Liability – concerns around competitive sports.
- Reduced recess in some districts.
- Academic testing pressures.
Many schools shifted from daily PE to once or twice per week, and some allowed waivers or substitutions.
Re-implementing structured, mandatory physical activity programs could have measurable benefits across several health concerns:
- Regular moderate activity reduces – childhood obesity; type 2 diabetes risk; early hypertension and abnormal cholesterol levels.
Consistent school-based activity is especially important for children from lower-income households who may lack access to private sports programs.
Mental Health benefits – research increasingly shows that exercise:
- Reduces symptoms of anxiety and depression.
- Improves mood regulation.
- Enhance attention and executive function.
- Supports resilience.
With rising youth mental health concerns nationwide, structured physical activity may serve as a preventive support system.
Academic Performance – contrary to earlier fears, increasing PE time does not reduce academic achievement. Many studies indicate that PE improves:
- Concentration
- Memory retention
- Classroom behavior
- On-task time
Short activity breaks during the school day are linked to better learning outcomes.

Rather than focusing solely on athletic performance, modern PE could emphasize lifelong health, inclusion and mental well-being.
Re-implementing structured physical education is not about nostalgia – it’s about measurable benefits. It does not require recreating the past. It means reviving the structure, consistency, and cultural priority that once made youth fitness a shared national value – while updating methods for today’s scientific understanding and diverse student needs.
Generations benefited from disciplined, structured physical education. Reintroducing those systems is not a step backward – it’s a practical, evidence-based investment in children’s long-term health, resilience, and productivity.
