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).

This report presents national anthropometric reference data for all ages of the U.S. population in 2003–2006, adding to results published previously from 1960–2002. These latest NHANES data add to the knowledge about trends in child growth and development and trends in the distribution of body measurements, such as weight and height, in the U.S. population.

The National Health and Nutrition Examination Survey has studied the height and weight of Americans for decades. Tables documenting the increase in both height and weight for children and adolescents aged 2-19 since 1963 can be found here.

Last Friday we released the 10th anniversary edition of America’s Children, a product of the Federal Interagency Forum on Child and Family Statistics.
The Federal Interagency Forum on Child and Family Statistics (Forum) is a collection of 22 Federal government agencies involved in research and activities related to children and families. The Forum was founded in 1994 and formally established in April 1997 under Executive Order No. 13045. The mission of the Forum is to foster coordination and collaboration and to enhance and improve consistency in the collection and reporting of Federal data on children and families. The Forum also aims to improve the reporting and dissemination of information on the status of children and families.
Quite a bit of media interest was generated (here | here) on the subject of teen sexual behavior but there was much more to the report. The full report is available here and our overview of the data on health indicators which we contributed to is below the fold.

We’ve written a couple of times on the subject of overweight and obesity. However, some of our research has been published in scholarly journals rather than on our website.
The journal Obesity: Racial and Ethnic Differences in Secular Trends for Childhood BMI, Weight, and Height
The journal Gastroenterology: The Epidemiology of Obesity. More data on overweight and at-risk of overweight in children.
The Journal of the American Medical Association. Prevalence of Overweight and Obesity.
The journal Clinical Nutrition and Obesity. Childhood Overweight and Family Income in the United States, 1999-2004.

Overweight and obesity data collected by the National Health and Nutrition Examination Survey for the National Center for Health Statistics show obesity increasing among Americans of all ages.
Obesity is defined as having a body mass index (BMI) of 30 or greater.
There is a subset of obesity called morbid or extreme obesity which is defined as having a BMI of 40 or greater or weighing in excess of 100 pounds of one’s ideal weight. The National Center for Health Statistics does not track that number.
However several of our scientists, writing in the Journal of the American Medical Association (JAMA) do report on this particular condition. For the period 2003-2004 almost 5 percent of adults were extremely obese.
There JAMA articles can be found here and here.
