NCHS releases a new report, “Mean Body Weight, Height, Waist Circumference, and Body Mass Index Among Children and Adolescents: United States, 1999–2018” that presents trends in mean weight, recumbent length, height, waist circumference, and body mass index (BMI) among children and adolescents in the United States from 1999 through 2018.
- No significant trends over time were observed in any of the body measures for children aged 2–5 years, except for an increase in mean BMI among girls.
- Among girls aged 6–11, mean height and waist circumference significantly increased from 1999–2000 through 2003–2004, and then significantly decreased for height but remained stable for waist circumference through 2017–2018.
- Among those aged 12–15, mean body weight and waist circumference increased over time among boys, and BMI increased among both boys and girls.
- Among adolescent boys aged 16–19, body weight significantly increased from 1999–2000 through 2009–2010 and
then significantly decreased through 2017–2018. In addition, height remained stable through 2009–2010 and then significantly decreased through 2017–2018.

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.
