Summer is upon us and with it we get a spate of questions concerning seasonal injuries and deaths. Lightning strikes. Lawn mower misadventures. Drownings. Heat stroke. And snake bites.

Injuries are tracked by the National Center for Injury Prevention and Control, one of 14 National Centers that together comprise the Centers for Disease Control and Prevention. At the National Center for Health Statistics we track mortality resulting from various injuries. This data comes to us by way of death certificates filed across the nation and collated at county and state level.

Fortunately, deaths from snake bite are rare.

Multiple Births

May 17, 2007

The twin birth rate rose 2 percent for 2004, to 32.2 twins per 1,000 total births, another record high. The twinning rate has climbed 42 percent since 1990 (from 22.6), and 70 percent since 1980 (18.9). The number of live births in twin deliveries rose to 132,219, nearly double the number reported for 1980 (from 68,339).

In contrast to the continued upswing in twin births, the rate of triplet and higher-order multiple births (triplet/+ birth rate) declined 6 percent for 2004, to 176.9 per 100,000, from 187.4 in 2003. The triplet/+ birth rate (the number of triplets, quadruplets, quintuplets, and other higher-order multiples per 100,000 live births) soared by more than 400 percent between 1980 and 1998 (from 37.0 to 193.5 per 100,000 births) (125). Since 1999, however, this rate has been comparatively stable, trending slightly downward; the current year level is 9 percent lower than the 1998 peak. In 2004, 7,275 triplets/+ were born, a drop of 5 percent from the previous year, and the lowest number reported since 1997. Similar trends in twinning and in triplet/+ birth rates have been observed over the last several decades in England and Wales.

Childhood Surgery

May 17, 2007

The question was raised concerning the number of children who undergo surgery.

 Our best source for this is our National Hospital Discharge Survey. Our most recent publication from this survey indicated some 2,310,000 surgical procedures were performed on patients under 15 years of age.

New Infant Mortality Report

May 4, 2007

The CDC’s National Center for Health Statistics has released a new report on infant mortality that has a lot of good news and some troubling numbers, too.

 The lede:

The infant mortality rate in the United States in 2004 was 6.78 infant (under 1 year of age) deaths per 1,000 live births, not significantly different from the rate of 6.84 in 2003, according to a new report released today by the Centers for Disease Control and Prevention’s National Center for Health Statistics. The report, “Infant Mortality Statistics from the 2004 Period Linked Birth/Infant Death Data Set,” also finds continued racial/ethnic disparities in infant mortality rates.

Non-Hispanic black women had the highest infant mortality rate in the United States in 2004 – 13.60 per 1,000 live births compared to 5.66 per 1,000 births among non-Hispanic white women. Women of Cuban ethnicity in the United States had the lowest infant mortality rate of 4.55 per 1,000 live births.

New Report on Oral Health

May 1, 2007

 Americans of all ages continue to experience improvements in their oral health. However, tooth decay in primary (baby) teeth increased among children aged 2 to 5 years, according to a report released today by the Centers for Disease Control and Prevention (CDC).

Based on data from CDC’s National Center for Health Statistics, the report, “Trends in Oral Health Status—United States, 1988–1994 and 1999–2004,” represents the most comprehensive assessment of oral health data available for the U.S. population to date. (more…)

CDC’s National Center for Health Statistics has released a new report on the oral health of Americans based on data from the National Health and Nutrition Examination Survey. Read or download the report here.
