New data in the latest Journal of the American Medical Association (JAMA) from NCHS statisticians show that the increasing rate of obesity may be slowing, although the prevalence of adults who are obese is still high. The numbers from 2007-2008 show that 33.8% of U.S. adults are obese (32.2% for men, 35.5% for women). The growth of the obesity rate in the U.S. over the past 40 years is depicted below.

Recently, the Centers for Disease Control and Prevention has released information concerning the prevalence and costs of the growing epidemic of obesity in the United States. Some of the most critical information concerning the weight of the nation is collected in the National Health and Nutrition Examination Survey (NHANES), which takes actual measurements of a nationally representative sample of the U.S. population.
For the most recent information on obesity and overweight, please visit the Health E-Stat report at http://www.cdc.gov/nchs/products/pubs/pubd/hestats/overweight/overweight_adult.htm.

Poor nutrition or underlying health conditions can sometimes cause a person to be underweight. Data from the 2003-2006 National Health and Nutrition Examination Survey (NHANES) showed that an estimated 1.8% of U.S. adults are underweight. Between 1988-1994 and 2003-2006, a statistically significant decrease in the percentage of those underweight was found only among those aged 60 and over. In this age group, the percentage underweight was 2.3% in 1988-1994 and 1.2% in 2003-2006.

Results from the 2003-2006 NHANES showed that about 3.3% of children and adolescents aged 2-19 years are underweight. Trends from 1971-1974 to 2003-2006 show that there has been an overall significant decrease in underweight children and adolescents, from 5.1% to 3.3%. Underweight significantly decreased from 5.8% to 2.8% among 2-5 year olds and from 5.3% to 2.7% among 6-11 year olds. Among adolescents aged 12-19, underweight decreased, although not significantly, from 4.7% to 3.8% during the same time period.

Young adults in the United States aged 18-29 face a number of health challenges, including increases in obesity, high injury rates, and a lack of insurance coverage compared to other adults, according to the latest report on the nation’s health from NCHS.
- Obesity rates have tripled among young adults in the past three decades, rising from 8 percent in 1971-74 to 24 percent in 2005-06.
In 2006, 29 percent of young men were current cigarette smokers compared to 21 percent of young adult women.
In 2005, unintentional injuries (‘‘accidents’’), homicide, and suicide accounted for 70 percent of deaths among young adults 18–29 years of age. Three-quarters of the 47,000 deaths in this age group occurred among young men.
In 2006, young adults aged 20–24 were more likely to be uninsured (34 percent) than those aged 18–19 (21 percent) and those aged 25–29 (29 percent).
