Abstract

Background: Unintentional injuries are the leading cause of death in the United States for persons aged 1\u201319 years and the fifth leading cause of death for newborns and infants aged <1 year. This report describes 10-year trends in unintentional injury deaths among persons aged 0\u201319 years.

Methods: CDC analyzed 2000\u20132009 mortality data from the National Vital Statistics System by age group, sex, race/ethnicity, injury mechanism, and state.

Results: From 2000 to 2009, the overall annual unintentional injury death rate decreased 29%, from 15.5 to 11.0 per 100,000 population, accounting for 9,143 deaths in 2009. The rate decreased among all age groups except newborns and infants aged <1 year; in this age group, rates increased from 23.1 to 27.7 per 100,000 primarily as a result of an increase in reported suffocations. The poisoning death rate among teens aged 15\u201319 years nearly doubled, from 1.7 to 3.3 per 100,000, in part because of an increase in prescription drug overdoses (e.g., opioid pain relievers). Childhood motor vehicle traffic\u2013related death rates declined 41%; however, these deaths remain the leading cause of unintentional injury death. Among states, unintentional injury death rates varied widely, from 4.0 to 25.1 per 100,000 in 2009.

Conclusions and Implications for Public Health Practice: Although the annual rate is declining, unintentional injury remains the leading cause of death among children and adolescents in the United States, led by motor vehicle traffic\u2013related deaths. Death rates from infant suffocation and teen poisoning are increasing. The 2012 National Action Plan for Child Injury Prevention provides actions in surveillance, research, communication, education, health care, and public policy to guide efforts in saving lives by reducing injuries.

Introduction

Unintentional injuries are the leading cause of death in the United States among persons aged 1\u201319 years, accounting for 37% of all deaths in this age group in 2009, and the fifth leading cause of death among newborns and infants aged <1 year (1). Unintentional injury deaths are responsible for more years of potential life lost before age 65 years than cancer, heart disease, or any other cause of death, in part because children and adolescents die from unintentional injuries much more commonly than other causes (1). For every childhood injury death, more than 1,000 are treated or receive medical consultation for a nonfatal injury (2). In 2009, child and adolescent unintentional injuries resulted in approximately 9,000 deaths, 225,000 hospitalizations, and 8.4 million patients treated and released from emergency departments (1). Unintentional injuries occurring in 2005 that resulted in death, hospitalization, or an emergency department visit cost nearly $11.5 billion in medical expenses (1). These injuries are preventable (3,4), and effective interventions for reducing childhood injuries are less costly than the medical expenses and productivity losses associated with those injuries (5).

The high incidence and preventability of child and adolescent unintentional injuries highlight the need for public health action. Although unintentional injury death rates have decreased in recent decades (6), rates remain high in some population subgroups and states (7). This report summarizes trends in unintentional injury deaths among persons aged 0\u201319 years, from 2000 to 2009, by age group, sex, race/ethnicity, injury mechanism, and state, using data from the National Vital Statistics System.

Methods

CDC's National Vital Statistics System collects death certificate data from 50 states and the District of Columbia.* Annual mortality files were analyzed for deaths among persons aged 0\u201319 years. Unintentional injury deaths were defined as those with an underlying cause of death classified by International Classification of Diseases, 10th Revision (ICD-10) external cause of injury codes as V01\u2013X59 or Y85\u2013Y86. Deaths were categorized by mechanism as drowning, fall, fire/burn, motor vehicle traffic\u2013related, other transportation-related, poisoning, suffocation, and all other, using the external cause-of-injury mortality matrix.\u2020 Motor vehicle traffic-related deaths were divided further into occupant, pedestrian, pedal cyclist, unspecified, and all other motor vehicle traffic\u2013related deaths. Race/ethnicity was coded into five mutually exclusive categories: Hispanic (of any race), and four non-Hispanic racial groups (white, black, American Indian/Alaska Native, and Asian/Pacific Islander). Annual death rates were calculated using population totals from the U.S. Census.\u00a7 Weighted least squares regression was used to test for linear trends in death rates over time, using all years of data. A p value of <0.05 indicated statistical significance.

Results

From 2000 to 2009, the overall annual unintentional injury death rate declined 29% among persons aged 0\u201319 years, from 15.5 to 11.0 per 100,000 (Table 1). The rate for males was higher than that for females in each age group. Among both males and females, the death rate declined 29%: from 19.9 to 14.1 per 100,000 for males and from 10.8 to 7.7 per 100,000 for females. A significant linear decline across all racial/ethnic groups was observed, with declines ranging from 21% among blacks to 38% among Asian/Pacific Islanders (Table 1). American Indian/Alaska Natives had the highest death rate throughout the study period, at 30.4 per 100,000 in 2000 and 23.8 in 2009, nearly double that of blacks (16.2 and 12.8), the population with the next highest rates in 2009.

By injury mechanism, motor vehicle traffic\u2013related death rates decreased 41%, from 9.3 to 5.5 per 100,000, yet that category recorded the most deaths in 2000 (7,497) and 2009 (4,564) to remain the leading cause of unintentional injury death among persons aged 0\u201319 years. Drowning, other transportation, fire/burn, fall, and all other unintentional injuries also showed significant linear declines, whereas both suffocation and poisoning showed significant linear increases (30% and 80%, respectively) (Table 1).

Death rates varied substantially by age group and mechanism, with the highest rates in the youngest (aged <1 year) and oldest (15\u201319 years) age groups (Figure). The overall rate decreased among all age groups except children aged <1 year, whose death rate increased from 23.1 to 27.7 per 100,000, surpassing rates among persons aged 15\u201319 years (Table 2). This increase can be attributed largely to a rise in suffocation death rates,\u00b6 which increased from 13.8 to 21.3 per 100,000, claiming the lives of 907 newborns and infants in 2009. The death rate for those aged 15\u201319 years declined 33%, from 33.4 to 22.3 per 100,000, most notably as a result of a 41% decline in motor vehicle traffic\u2013related death rates from 25.3 to 15.1 per 100,000. However, poisoning death rates in the 15\u201319 year age group increased by 91%, from 1.7 to 3.3 per 100,000 over the same period (Table 2).

Wide variations in death rates were found among states, with 2009 rates ranging from 4.0 per 100,000 in Massachusetts and 4.5 in New Jersey to 23.6 per 100,000 in South Dakota and 25.1 in Mississippi (Table 3). In 11 states, death rates were significantly lower than the overall national rate of 11.0 per 100,000, and 21 states had rates that were significantly higher than 11.0. No states had significant linear increases in child and adolescent unintentional injury death rates; however, 31 states showed significant linear decreases. The largest decreases occurred in Delaware, Oregon, Iowa, and Virginia, where rates declined by at least 45%.

Conclusions and Comments

This report is the first from CDC to describe trends over time in child and adolescent unintentional injury deaths by mechanism and state. Population subgroup results generally are consistent with previous research. For example, males had higher death rates than females in each age group, racial/ethnic differences were observed with the highest rates among American Indians/Alaska Natives, and motor vehicle traffic\u2013related injuries were the leading cause of unintentional injury death among the three oldest age groups (7,8). The wide variations in death rates among states suggest that environment, exposure to hazards (e.g., vehicle miles traveled, exposure to water settings, urban or rural environment), and differences in public policy might play a role. In 2009, if the overall national rate had been equal to the lowest state unintentional injury death rate, 5,785 lives would have been saved.

The high incidence of infant suffocation underscores the importance of a safe sleeping environment as recommended by the American Academy of Pediatrics, which includes supine positioning, a firm sleep surface, room-sharing without bed-sharing, and avoiding loose bedding (9). CDC has developed the Sudden Unexpected Infant Death (SUID) Case Registry, aimed at better understanding and ultimately preventing SUID deaths, which include suffocation in bed.**

The increasing trend in poisoning deaths among those aged 15\u201319 years is consistent with the reported increases in drug poisoning deaths seen in the U.S. population overall during this period (10). Poisoning deaths from prescription drug misuse is a growing concern (11); during 2002\u20132004 an estimated 13.5% of those aged 12\u201317 years reported ever having misused prescription drugs (12). The percentage of poisoning deaths among those aged 15\u201319 years with prescription drugs as a contributing cause increased from 30% in 2000 to 57% in 2009 (13). Strategies to reduce the misuse of prescription drugs include appropriate prescribing, proper storage and disposal, discouraging medication sharing, and state-based prescription drug monitoring programs (11).

Improvements in seat belt use, child safety seat and booster seat use, licensing requirements, vehicle design, the road environment, and reductions in alcohol-impaired driving likely contributed to the decline in motor vehicle traffic\u2013related deaths (4,14). Despite this success, traffic crashes remain the leading cause of death for persons in age groups 5\u201319 years, accounting for 67% of unintentional injury deaths and 28% of deaths from all causes among those aged 15\u201319 years in 2009 (1). Increasing seat belt use and implementing components of graduated driver licensing practices, such as limiting nighttime driving and limiting teen passengers, likely can lead to further declines. Parents can learn how to reduce their teens' risks of motor vehicle-related injury through the CDC's teen driving initiative, Parents are the Key (http://www.cdc.gov/parentsarethekey/index.html). For communities, the Guide to Community Preventive Services provides evidenced-based strategies to reduce motor vehicle traffic\u2013related injuries (e.g., laws mandating child safety seat use and primary enforcement of seat belt use, and multiple measures to reduce alcohol-impaired driving) (http://www.thecommunityguide.org/mvoi/index.html).

Even with the reported declines, the U.S. unintentional injury death rate among persons aged 0\u201319 years does not compare favorably with other developed countries. Among the 34 Organization for Economic Cooperation and Development countries, the U.S. unintentional injury death rate for persons aged 0\u201314 years ranked 30th in 2008, with a rate four times higher than the top performing nations (15). Among persons aged 0\u201319 years, unintentional injury death rates in 2004 in the United States were almost twice the combined rates of high-income countries in the World Health Organization's European and Western Pacific Regions (4).

The findings in this report are subject to at least two limitations. First, fatalities are based on death certificate data and are subject to misclassification errors if a mechanism is not specified correctly on the death certificate or if classification standards have changed over time. For example, challenges in distinguishing between sudden infant death syndrome and suffocation combined with reporting differences among those completing death certificates might be contributing factors in the increase in reported suffocation deaths among newborns and infants (9). Second, this report is limited to unintentional injury deaths; excluding nonfatal injuries substantially underreports the total burden from injury on society and the medical care system (1).

The frequency and cost of child and adolescent unintentional injury deaths, along with the effectiveness of existing public health interventions, make injury prevention a priority for improving the health of children and adolescents. Efforts to prevent these deaths likely will result in fewer nonfatal injuries as well. Although unintentional injury death rates are declining, findings reported here demonstrate the need to take further action. CDC has developed the Protect the Ones You Love Initiative to help parents reduce unintentional injuries from burns, drowning, falls, poisonings, motor vehicle crashes, suffocation, and sports (http://www.cdc.gov/safechild). Health-care providers, educators, community members and others also can take steps to reduce child injury. CDC and its partners have released the National Action Plan for Child Injury Prevention, providing actions in surveillance, research, communication, education, health care, and public policy (http://www.cdc.gov/safechild/nap). Implementing the National Action Plan could result in significant reductions in needless deaths, injuries, and costs associated with injuries among children and adolescents in the United States.

Key Points

Unintentional injuries are the leading cause of death among persons aged 1\u201319 years and the fifth leading cause of death for newborns and infants aged <1 year. Nearly two in five deaths among persons aged 1\u201319 years are caused by unintentional injuries.
From 2000 to 2009, the overall unintentional injury death rate among persons aged 0\u201319 years decreased 29%, from 15.5 to 11.0 per 100,000. Motor vehicle traffic\u2013related deaths declined, but remain the leading cause of injury deaths.
Wide variations in death rates were found among states with the rate for Mississippi more than six times the rate for Massachusetts.
Unintentional infant suffocation death rates increased 54% during 2000\u20132009, driving the overall increase in newborn and infant unintentional injury death rates.
Poisoning death rates increased 91% among persons aged 15\u201319 years.
Unintentional injury deaths are preventable, and efforts to increase child and adolescent safety through evidence-based prevention initiatives can reduce death rates even further.
The National Action Plan for Child Injury Prevention provides a framework to address child unintentional injury prevention with specific actions in surveillance, research, communication, education, health care, and public policy (http://www.cdc.gov/safechild/nap). Taking steps to implement the National Action Plan could result in substantial reductions in needless deaths, injuries, and costs associated with injuries among children and adolescents in the United States.

Abbreviation: NA = not applicable. * Per 100,000 population. \u2020 Percentage change might not match calculations because of rounding. \u00a7 P value from weighted least squares regression to assess linear trend significance during 2000\u20132009. \u00b6 The District of Columbia was excluded because of low death counts in all years; however District of Columbia deaths are included in the overall U.S. death rate. ** Significance determined using Z-test for states with \u2265100 deaths and 95% confidence intervals from a gamma distribution for states with <100 deaths in 2009. \u2020\u2020 With 17 deaths, rate for Vermont in 2009 was unstable and thus cannot be statistically compared with the overall U.S. death rate. \u00a7\u00a7 Death rates based on fewer than 20 deaths have been suppressed for unreliability.
