Prevalence of Overweight and Obesity in the United States, 1999-2004
TL;DR: These estimates suggest that the increases in body weight are continuing in men and in children and adolescents while they may be leveling off in women; among women, no overall increases in the prevalence of obesity were observed.
Abstract: ContextThe prevalence of overweight in children and adolescents and obesity in adults in the United States has increased over several decades.ObjectiveTo provide current estimates of the prevalence and trends of overweight in children and adolescents and obesity in adults.Design, Setting, and ParticipantsAnalysis of height and weight measurements from 3958 children and adolescents aged 2 to 19 years and 4431 adults aged 20 years or older obtained in 2003-2004 as part of the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of the US population. Data from the NHANES obtained in 1999-2000 and in 2001-2002 were compared with data from 2003-2004.Main Outcome MeasuresEstimates of the prevalence of overweight in children and adolescents and obesity in adults. Overweight among children and adolescents was defined as at or above the 95th percentile of the sex-specific body mass index (BMI) for age growth charts. Obesity among adults was defined as a BMI of 30 or higher; extreme obesity was defined as a BMI of 40 or higher.ResultsIn 2003-2004, 17.1% of US children and adolescents were overweight and 32.2% of adults were obese. Tests for trend were significant for male and female children and adolescents, indicating an increase in the prevalence of overweight in female children and adolescents from 13.8% in 1999-2000 to 16.0% in 2003-2004 and an increase in the prevalence of overweight in male children and adolescents from 14.0% to 18.2%. Among men, the prevalence of obesity increased significantly between 1999-2000 (27.5%) and 2003-2004 (31.1%). Among women, no significant increase in obesity was observed between 1999-2000 (33.4%) and 2003-2004 (33.2%). The prevalence of extreme obesity (body mass index ≥40) in 2003-2004 was 2.8% in men and 6.9% in women. In 2003-2004, significant differences in obesity prevalence remained by race/ethnicity and by age. Approximately 30% of non-Hispanic white adults were obese as were 45.0% of non-Hispanic black adults and 36.8% of Mexican Americans. Among adults aged 20 to 39 years, 28.5% were obese while 36.8% of adults aged 40 to 59 years and 31.0% of those aged 60 years or older were obese in 2003-2004.ConclusionsThe prevalence of overweight among children and adolescents and obesity among men increased significantly during the 6-year period from 1999 to 2004; among women, no overall increases in the prevalence of obesity were observed. These estimates were based on a 6-year period and suggest that the increases in body weight are continuing in men and in children and adolescents while they may be leveling off in women.

TL;DR: The increases in the prevalence of obesity previously observed do not appear to be continuing at the same rate over the past 10 years, particularly for women and possibly for men.
Abstract: Results In 2007-2008, the age-adjusted prevalence of obesity was 33.8% (95% confidence interval [CI], 31.6%-36.0%) overall, 32.2% (95% CI, 29.5%-35.0%) among men, and 35.5% (95% CI, 33.2%-37.7%) among women. The corresponding prevalence estimates for overweight and obesity combined (BMI 25) were 68.0% (95% CI, 66.3%-69.8%), 72.3% (95% CI, 70.4%-74.1%), and 64.1% (95% CI, 61.3%66.9%). Obesity prevalence varied by age group and by racial and ethnic group for both men and women. Over the 10-year period, obesity showed no significant trend among women (adjusted odds ratio [AOR] for 2007-2008 vs 1999-2000, 1.12 [95% CI, 0.89-1.32]). For men, there was a significant linear trend (AOR for 2007-2008 vs 1999-2000, 1.32 [95% CI, 1.12-1.58]); however, the 3 most recent data points did not differ significantly from each other.

TL;DR: The increases in the prevalences of obesity and overweight previously observed continued in 1999-2000, and increases occurred for both men and women in all age groups and for non-Hispanic whites, non- Hispanic blacks, and Mexican Americans.
Abstract: ContextThe prevalence of obesity and overweight increased in the United States
between 1978 and 1991. More recent reports have suggested continued increases
but are based on self-reported data.ObjectiveTo examine trends and prevalences of overweight (body mass index [BMI]
≥25) and obesity (BMI ≥30), using measured height and weight data.Design, Setting, and ParticipantsSurvey of 4115 adult men and women conducted in 1999 and 2000 as part
of the National Health and Nutrition Examination Survey (NHANES), a nationally
representative sample of the US population.Main Outcome MeasureAge-adjusted prevalence of overweight, obesity, and extreme obesity
compared with prior surveys, and sex-, age-, and race/ethnicity–specific
estimates.ResultsThe age-adjusted prevalence of obesity was 30.5% in 1999-2000 compared
with 22.9% in NHANES III (1988-1994; P<.001).
The prevalence of overweight also increased during this period from 55.9%
to 64.5% (P<.001). Extreme obesity (BMI ≥40)
also increased significantly in the population, from 2.9% to 4.7% (P = .002). Although not all changes were statistically significant,
increases occurred for both men and women in all age groups and for non-Hispanic
whites, non-Hispanic blacks, and Mexican Americans. Racial/ethnic groups did
not differ significantly in the prevalence of obesity or overweight for men.
Among women, obesity and overweight prevalences were highest among non-Hispanic
black women. More than half of non-Hispanic black women aged 40 years or older
were obese and more than 80% were overweight.ConclusionsThe increases in the prevalences of obesity and overweight previously
observed continued in 1999-2000. The potential health benefits from reduction
in overweight and obesity are of considerable public health importance.

TL;DR: The 2000 CDC growth charts were developed with improved data and statistical procedures and now have an instrument for growth screening that better represents the racial-ethnic diversity and combination of breast- and formula-feeding in the United States.
Abstract: Objectives This report provides detailed information on how the 2000 Centers for Disease Control and Prevention (CDC) growth charts for the United States were developed, expanding upon the report that accompanied the initial release of the charts in 2000. Methods The growth charts were developed with data from five national health examination surveys and limited supplemental data. Smoothed percentile curves were developed in two stages. In the first stage, selected empirical percentiles were smoothed with a variety of parametric and nonparametric procedures. In the second stage, parameters were created to obtain the final curves, additional percentiles and z-scores. The revised charts were evaluated using statistical and graphical measures. Results The 1977 National Center for Health Statistics (NCHS) growth charts were revised for infants (birth to 36 months) and older children (2 to 20 years). New body mass index-for-age (BMI-for-age) charts were created. Use of national data improved the transition from the infant charts to those for older children. The evaluation of the charts found no large or systematic differences between the smoothed percentiles and the empirical data. Conclusion The 2000 CDC growth charts were developed with improved data and statistical procedures. Health care providers now have an instrument for growth screening that better represents the racial-ethnic diversity and combination of breast- and formula-feeding in the United States. It is recommended that these charts replace the 1977 NCHS charts when assessing the size and growth patterns of infants, children, and adolescents.

TL;DR: The NHANES results indicate continuing disparities by sex and between racial/ethnic groups in the prevalence of overweight and obesity among adults and overweight among children, using the most recent national data of height and weight measurements.
Abstract: ContextThe prevalence of overweight and obesity has increased markedly in the
last 2 decades in the United States.ObjectiveTo update the US prevalence estimates of overweight in children and
obesity in adults, using the most recent national data of height and weight
measurements.Design, Setting, and ParticipantsAs part of the National Health and Nutrition Examination Survey (NHANES),
a complex multistage probability sample of the US noninstitutionalized civilian
population, both height and weight measurements were obtained from 4115 adults
and 4018 children in 1999-2000 and from 4390 adults and 4258 children in 2001-2002.Main Outcome MeasurePrevalence of overweight (body mass index [BMI] ≥95th percentile
of the sex-specific BMI-for-age growth chart) among children and prevalence
of overweight (BMI, 25.0-29.9), obesity (BMI ≥30.0), and extreme obesity
(BMI ≥40.0) among adults by sex, age, and racial/ethnic group.ResultsBetween 1999-2000 and 2001-2002, there were no significant changes among
adults in the prevalence of overweight or obesity (64.5% vs 65.7%), obesity
(30.5% vs 30.6%), or extreme obesity (4.7% vs 5.1%), or among children aged
6 through 19 years in the prevalence of at risk for overweight or overweight
(29.9% vs 31.5%) or overweight (15.0% vs 16.5%). Overall, among adults aged
at least 20 years in 1999-2002, 65.1% were overweight or obese, 30.4% were
obese, and 4.9% were extremely obese. Among children aged 6 through 19 years
in 1999-2002, 31.0% were at risk for overweight or overweight and 16.0% were
overweight. The NHANES results indicate continuing disparities by sex and
between racial/ethnic groups in the prevalence of overweight and obesity.ConclusionsThere is no indication that the prevalence of obesity among adults and
overweight among children is decreasing. The high levels of overweight among
children and obesity among adults remain a major public health concern.

TL;DR: The prevalence of overweight among children in the United States is continuing to increase, especially among Mexican-American and non-Hispanic black adolescents.
Abstract: ContextThe prevalence of overweight among children in the United States increased
between 1976-1980 and 1988-1994, but estimates for the current decade are
unknown.ObjectiveTo determine the prevalence of overweight in US children using the most
recent national data with measured weights and heights and to examine trends
in overweight prevalence.Design, Setting, and ParticipantsSurvey of 4722 children from birth through 19 years of age with weight
and height measurements obtained in 1999-2000 as part of the National Health
and Nutrition Examination Survey (NHANES), a cross-sectional, stratified,
multistage probability sample of the US population.Main Outcome MeasurePrevalence of overweight among US children by sex, age group, and race/ethnicity.
Overweight among those aged 2 through 19 years was defined as at or above
the 95th percentile of the sex-specific body mass index (BMI) for age growth
charts.ResultsThe prevalence of overweight was 15.5% among 12- through 19-year-olds,
15.3% among 6- through 11-year-olds, and 10.4% among 2- through 5-year-olds,
compared with 10.5%, 11.3%, and 7.2%, respectively, in 1988-1994 (NHANES III).
The prevalence of overweight among non-Hispanic black and Mexican-American
adolescents increased more than 10 percentage points between 1988-1994 and
1999-2000.ConclusionThe prevalence of overweight among children in the United States is
continuing to increase, especially among Mexican-American and non-Hispanic
black adolescents.
