What Are the Leading Causes of Wrongful Death for Teenagers?

What are the common causes of fatal injuries in teens?

A 2018 study published in The New England Journal of Medicine titled “The Major Causes of Death in Children and Adolescents” sheds some light on the most common causes of fatalities in children aged 1 to 110 years. The study finds that, of the 20,630 deaths in that age group in the US in 2016;

“More than 60% resulted from injury-related causes, which included 6 of the 10 leading causes of death…when we examined all deaths among children and adolescents according to intent, unintentional injuries were the most common cause of injury-related death (57%; 7047 of 12,336 deaths) …

Motor vehicle crashes were the leading cause of death for children and adolescents, representing 20% of all deaths; firearm-related injuries were the second leading cause of death, responsible for 15% of deaths…the fourth leading cause of death was suffocation, responsible for 7% of all deaths.”

That’s a little complicated, so let’s break it down a little differently; of the 20,630 deaths in 2016, more than half were the result of unintentional injuries. According to the authors, the majority of fatalities studied (68%) occurred in adolescents aged 10 to 19. In that group, the leading cause of the unintentional injury was motor-vehicle crashes, followed by firearm injuries and then suffocation.

Let’s take a minute to discuss unintentional injuries. Unintentional in this case means unplanned, and unplanned injuries (by any other name) are accidents. Taking this all together, fully 14,028 adolescents between the ages of 10 and 110 years were killed under fully preventable circumstances.

But why are teenagers so likely to suffer fatal injuries in these categories? At the risk of repeating ourselves, teenagers have less experience navigating the world. Developmentally speaking, teenagers are ill-prepared to understand their own limitations and tend to engage in more risk-taking behavior – especially in the presence of peers. Finally, some teens are beginning to experiment with substance use that may additionally impair judgement.

While these reasons may explain that teens are more likely to engage in riskier behavior and thus why unintentional injuries more often result in fatalities, it doesn’t completely explain the why of it all. For the answer to that, we turn to the Australian non-profit Raising Children. They explain, “Because the prefrontal cortex is still developing, teenagers might rely on a part of the brain called the amygdala to make decisions and solve problems more than adults do.”

The amygdala is more associated with emotions, impulses, aggression, and instinct, resulting in emotionally driven decision-making. Based on the evidence, this has dire consequences when motor vehicles are involved. A 2019 article published in the journal Sustainability analyzed the mistakes most new drivers make and found that, “…novice drivers engage in three main risky behaviors: easily changing their attitudes, overestimating their driving skills, and underestimating illegal driving.”

You should also be aware that some teenagers are at higher risk of wrongful death injuries than others. From a National Center for Health Statistics Data Brief:

“Male teenagers are more likely to die than female teenagers at every single year of age from 12 to 110 years, and older teenagers are at higher risk of dying than younger teenagers. At age 12, for example, the death rate for males (20.2 deaths per 100,000) is 46 percent higher than the rate for females (13.8 deaths per 100,000). At age 19 the death rate for males (135.2 deaths per 100,000) is almost three times the rate for females (46.1 deaths per 100,000).”
