podcast-iconHOST:  In March of 2020, field operations for the National Health and Nutrition Examination Survey – or NHANES – were halted due to the COVID-19 pandemic. Field operations are scheduled to restart later this summer.  But the halt in operations presented a problem, since NHANES data traditionally is released in two-year cycles in order to have a large enough sample size to be nationally representative.  Because the data collected in the cycle from 2019 thru March 2020 are ­not nationally representative, NCHS took steps to combine these “partial-cycle” data with previously released 2017–2018 data in order to produce nationally representative estimates.

This effort resulted in a new report this week that explains these “prepandemic NHANES data files,” from the period January 2017 thru March 2020, and outlines recommendations as well as limitations related to using the files.  The new report also presents prevalence estimates for selected health outcomes based on these files.

One of the health topics selected was obesity.  From January 2017 to March 2020, the data show that 1 in 5 children and adolescents in the U.S. were obese, or 19.7% of the age 2-19 population.  The report also shows that nearly half of children and adolescents – or 46% – had untreated or restored cavities in one or more of their primary or permanent teeth.

Among adults age 20 and up, the age-adjusted prevalence of obesity was more than 4 in 10, or 42%, and nearly 1 in 10 were severely obese. In addition to obesity, the new data show that diabetes prevalence among adults was nearly 15% and that nearly half of adults age 18 and over – or 45% — had hypertension.  Also, among older adults age 65 and up, complete tooth loss was present in nearly 14% of that population.

Ultimately, these new estimates are similar to those reported during the 2017-2018 cycle, but the additional year and two plus months-worth of data provide a larger sample size and thus more precise estimates.  And the release of these data mark another important milestone, in that they are the last NHANES data collected before widespread transmission of COVID-19 began in 2020.

HOST:  This week, the monthly provisional numbers for drug overdose deaths in the U.S. were released.  The latest round of data cover the one-year period ending in November of 2020, and show that the number of drug overdose deaths increased nearly 30% from the one-year period ending in November 2019.  Over 92,000 Americans died of drug overdoses in the year ending in November 2020, up from less than 72,000 the year before.

Three out of every four of these overdose deaths involved opioids, as the number of opioid-involved deaths topped 69,000 in this one-year period ending in November 2020, a major increase from 50,504 deaths the year before.  It’s important to note that recent trends may still be at least partially due to incomplete data.

A big factor behind the increase in overdose deaths is the continued increase in deaths involving synthetic opioids, primarily fentanyl.  But increases in deaths from other drugs are playing a major role as well.  Overdose deaths from cocaine as well as psychostimulants such as methamphetamine have shown significant increases compared to the previous year.

The next release of provisional numbers will feature full-year 2020 data for the first time.

HOST:  An average of 3.4 million emergency department visits occur each year due to injuries from motor vehicle crashes.  Most people who are injured or killed in motor vehicle crashes are occupants.  Studies have shown that medical care costs and productivity losses associated with motor vehicle injuries and deaths exceeded $75 billion in 2017.

Today, NCHS released a new report that presents emergency department visit rates per 1,000 for motor vehicle crashes by age, race and ethnicity, health insurance status, and census region. The data come from the National Hospital Ambulatory Medical Care Survey, an annual, nationally representative survey of nonfederal, general, and short-stay hospitals in the United States.

The report shows that in 2017–2018, the overall ER visit rate for motor vehicle crash injuries was 5.3 visits per 1,000, and was highest among patients between ages 15 and 24.  The ER visit rate for non-Hispanic black patients was several times higher than for non-Hispanic white or Hispanic patients.

Emergency department visit rates were higher for patients who had Medicaid, no insurance, or workers’ compensation insurance as their primary expected source of payment compared with patients who had private insurance or Medicare.  The ER visit rate for motor vehicle crashes at hospitals located in the South was higher than the rates at hospitals in all other census regions of the United States.


QuickStats: Age-Adjusted Death Rates for Four Selected Mechanisms of Injury — National Vital Statistics System, United States, 1979–2019

May 21, 2021

In 1979, of the four mechanisms of injury, age-adjusted mortality rates were highest for motor vehicle traffic deaths and lowest for drug poisoning deaths.

From 1979 to 2019, the age-adjusted rate of motor vehicle traffic deaths decreased from 22.1 per 100,000 to 11.1, and the rate of firearm-related deaths decreased from 14.7 to 11.9.

During the same period, the rate of drug poisoning (overdose) deaths increased from 3.0 to 21.6, and the rate of fall-related deaths increased from 6.2 to 10.1. In 2019, the rates were highest for drug poisoning deaths and lowest for fall-related deaths.

Motor Vehicle Traffic Death Rates, by Sex, Age Group, and Road User Type: United States, 1999–2019

March 18, 2021

A new NCHS report provides national trends in motor vehicle traffic deaths by sex, age group, and type of road user (i.e., motor vehicle occupant, motorcyclist, pedestrian, or pedal cyclist) from 1999 through 2019 using the latest mortality data from the National Vital Statistics System.

Findings:

  • Motor vehicle traffic death rates were stable from 1999 to 2006, declined on average by 8% each year from 2006 (14.5 per 100,000) to 2010 (10.7), and then increased from 2010 through 2019 (11.1).
  • Among males, differences in the rates by age group diminished over time; by 2019, the rate for males aged 15–24, the group with the highest rate in 1999, was lower than the rate for males aged 25–64 and 65 and over.
  • Among females, rates for all age groups decreased from 1999 through 2019.
  • Rates for motor vehicle occupants decreased by 37% from 12.0 in 1999 to 7.6 in 2019.

QuickStats: Motor-Vehicle–Traffic Death Rates Among Persons Aged 15–24 Years and ≥25 Years — United States, 2000–2019

February 26, 2021

From 2000 to 2006, rates of death caused by motor-vehicle–traffic injuries among persons aged 15–24 years and ≥25 years did not change significantly.

From 2006 to 2010, motor-vehicle–traffic death rates per 100,000 population declined among those aged 15–24 years, from 25.1 (2006) to 16.1 (2010), and among those aged ≥25 years, from 15.9 (2006) to 12.5 (2010).

Throughout most of the period, motor-vehicle–traffic death rates were higher among persons aged 15–24 years; however, motor-vehicle–traffic death rates began to converge in more recent years, and by 2019, the difference in the rate among those aged 15–24 years (13.7) and those aged ≥25 years (13.6) was not statistically significant.
