QuickStats: Percentage of Children and Teens Aged 6–17 Years Who Missed More Than 10 Days of School in the Past 12 Months Because of Illness or Injury, by Serious Emotional or Behavioral Difficulties Status and Age Group

November 13, 2017

During 2014–2016, children aged 6–17 years whose parent or guardian indicated the child had serious emotional or behavioral difficulties (EBDs) were almost four times as likely to miss more than 10 days of school because of illness or injury compared with children without serious EBDs (13.4% compared with 3.5%).

Among children with serious EBDs, those aged 6–10 years were less likely (8%) to miss more than 10 days of school compared with children aged 11–14 years (15.6%) and children aged 15–17 years (19.5%).

Among children without serious EBDs those aged 15–17 years (4.7%) were more likely to miss >10 school days compared with children aged 6–10 years (3%) and children aged 11–14 years (3.3%).

Questions for Yahtyng Sheu, Senior Service Fellow and Lead Author on “Sports and Recreation Related Injury Episodes in the United States, 2011-2014

Q: How many sports and recreation related injuries are being reported annually?

YS: According to our analysis, approximately 8.6 million of sports- and recreation- related injury episodes were reported annually among persons aged 5 and over using data from the 2011-2014 National Health Interview Survey. These injury episodes were medically-attended, for which a health care professional was contacted, either in person or by telephone, for advice or treatment. Therefore, these injury episodes were not limited to those resulted in emergency department visit or hospitalization.

Q: Did the sports and recreation related injuries differ by sex and age group? If so how?

YS: Yes. The distribution of sports- and recreation-related injuries differed by both sex and age. Approximately 60% of all the sports- and recreation-related injuries were sustained by men. Children and young adults between age 5 and 24 years old also accounted for 65% of the total sport- and recreation-related injuries.

Q: What types of sports and recreation activities are causing these injuries?

YS: Our data shows that general exercise, which includes aerobics, exercising, weight training, running, jogging, and school related activity, was the most frequently mentioned activity associated with sports-and recreation-related injuries. However, it does not mean that general exercise is more likely to “cause” injuries. We are unable to study what activities are more likely to cause injuries because the National Health Interview Survey do not collect data on activity participation. This prevents us from evaluating the risk of injury for individual activity.

Q: What parts of the body were more frequently injured while engaging in sports and recreation?

YS: Lower (42%) and upper (30%) extremities were the most frequently mentioned parts of body injured while engaging in the sports and recreation activity.

Q: Why did you decide to look at sports and recreation related injuries?

YS: Many epidemiological studies of sports- and recreation-related injuries have focused on specific populations, sport activities, or outcomes. Limited number of studies have provided national estimates on overall sports- and recreation-related injuries among all population. The latest national estimates on these type of injuries (that are not limited to emergency department visits data) were derived from 1997-1999 data. As more people engage in sports and recreation activity, we feel there is a need to address the patterns of sports- and recreation- related injuries using more recent data.

Injury Mortality: United States, 1999–2014

October 21, 2016

NCHS has released new data visualization that depicts injury mortality in the United States from 1999 through 2014.

This storyboard allows the user to select subcategories of injury deaths based on intent and mechanism of injury.

Numbers and rates are provided for the subcategory selected by the user.

The storyboard includes six dashboards. Deaths can be grouped or separated by mechanism of injury, intent of injury, and selected demographics (sex, age group, race and Hispanic origin).

Drop-down boxes across the top of the dashboard control the display of the entire visualization. The dashboards feature:

Rates: Line charts displaying trends for injury death rates. Both fixed and dynamic scale line charts are provided. The fixed scale line chart allows the user to see changes in rates relative to a predefined y-axis, while the dynamic scale line chart adjusts to maximize the visualization of the trend for the options selected. A dialog box on the left of the dashboard allows the user to select among several options for the range of y-axis values used in the fixed scale line chart.

Numbers of deaths: A table describes numbers of injury deaths for selections made at the top of the visualization.

National Hospital Care Survey Demonstration Projects: Traumatic Brain Injury

July 27, 2016

A new report from NCHS examines traumatic brain injury (TBI) encounters in various hospital settings. While the National Hospital Care Survey (NHCS) data used were not nationally representative, the results presented are consistent with previous research studies.

Analyses were conducted to highlight the tremendous analytical capabilities of NHCS, capabilities that have not been available before in previous surveys. New data elements such as intensive care use and diagnostic and physical services received, and the ability to link individuals in NHCS across hospital settings are used in the analyses.


  • Males have more TBI encounters than females across the inpatient, Emergency Department (ED), and Outpatient Department (OPD) settings and across all age groups.
  • Children under age 15 comprise most ED visits for TBI.
  • Adults aged 65 and over accounted for most TBI hospitalizations.
  • Falls were the most common cause of TBI encounters.


Increases in Medically Attended Nonfatal Injury Episodes Among Females in the United States

July 14, 2016

Analysis of mortality and emergency department (ED) data have historically shown higher injury rates among males than females. In 2014, the injury-related death rate was 85.5 per 100,000 population for males and 36.3 for females.

In 2013, 10,746 injury-related ED visits were made per 100,000 population for males and 8,957 for females. The National Health Interview Survey (NHIS) collects information on medically attended nonfatal injury episodes, providing national estimates beyond deaths and ED visits.

NCHS has released a report that describes changes in injury episodes in the female population, comparing estimates in 2005–2008 and 2011–2014 by age group, race and ethnicity, cause of injury, and location of injury.


  • From 2005–2008 to 2011–2014, the nonfatal injury rate increased for females but remained unchanged for males.
  • In 2005–2008, males had a higher nonfatal injury rate than females; however, in 2011–2014, the rates for males and females were similar.
  • From 2005–2008 to 2011–2014, the nonfatal injury rate increased significantly for women aged 45–64 and for non-Hispanic white females.
  • The increase in the nonfatal injury rate among females over time could not be attributed to a specific cause or place of injury occurrence.

QuickStats: Percentage of Traumatic Brain Injury (TBI)–Related Deaths by Underlying Cause and Age Group — United States, 2013

May 27, 2015

The causes of injury that result in TBI-related deaths vary by age group. In 2013, 77% of the TBI-related deaths among infants aged <1 year were from causes other than transportation, firearms, or falls, and primarily resulted from assault and maltreatment.

Transportation accounted for 53% of the TBI-related deaths among children aged 1–14 years. Firearm-related injuries accounted for 50% and 52% of the TBI-related deaths for persons aged 15–24 and 25–64 years, respectively. Most of the firearm-related TBI deaths in these two age groups were suicides (62% and 83%, respectively).

The majority (61%) of TBI-related deaths for those aged ≥65 years resulted from falls.

Deaths From Unintentional Injury Among Adults Aged 65 and Over: United States, 2000–2013

May 8, 2015

Injury deaths place a large burden on society, and many of these deaths are preventable.

In 2013, unintentional injuries were the eighth leading cause of death among U.S. adults aged 65 and over, resulting in nearly 46,000 deaths.

NCHS has released a report that describes trends in unintentional injury deaths among this age group from 2000 through 2013, highlighting differences by age, race and ethnicity, and urbanization for the five leading causes of unintentional injury death: falls, motor vehicle traffic crashes, suffocation, poisoning, and fire.

Key Findings from the Report:

  • In 2012–2013, 55% of all unintentional injury deaths among adults aged 65 and over were due to falls.
  • From 2000 through 2013, the age-adjusted fall injury death rate among adults aged 65 and over nearly doubled from 29.6 per 100,000 to 56.7 per 100,000.
  • In 2012–2013, the death rate due to suffocation was more than 8 times higher among adults aged 85 and over (26.5 per 100,000) compared with adults aged 65–74 (3.1 per 100,000).
  • Among adults aged 65 and over, the death rate due to fire was more than twice as high for non-Hispanic black adults as for non-Hispanic white and Hispanic adults.
  • The death rate from motor vehicle traffic crashes among adults aged 65 and over was 1.7 times higher in nonmetropolitan areas compared with metropolitan areas.


Injury-related Emergency Department Visits by Children and Adolescents: United States, 2009–2010

May 6, 2014

Injury is the leading cause of death and a major source of morbidity among children and adolescents in the United States. The emergency department (ED) plays an important role in the care of injuries, and these visits often represent the initial contact with a provider for the injury.

A new report from NCHS examines nationally representative data on injury-related ED visits by children and adolescents aged 18 years and under in the United States during 2009–2010. Injury-related ED visit rates were also compared for the age groups 0–4, 5–12, and 13–18 years, as these correspond to the preschool, school-age, and teen life periods respectively.


Key Findings from the Report:

  • In 2009–2010, an annual average of 11.9 million injury-related emergency department (ED) visits were made by children and adolescents aged 18 years and under in the United States.
  • The injury-related ED visit rate was 151 per 1,000 persons aged 18 years and under, and rates were higher for males than for females for all age groups (0–4 years, 5–12 years, and 13–18 years).
  • The injury-related ED visit rates among persons aged 5–12 years and 13–18 years were higher for non-Hispanic black persons than for other race and ethnicity groups.
  • Leading causes of injury-related ED visits among both males and females included falls and striking against or being struck unintentionally by objects or persons. Visit rates were higher for males than for females for both of these causes.
