Data characterization

  • Data for this indicator are obtained from an ongoing continuous survey conducted by the National Center for Health Statistics.
  • Survey data are representative of the U.S. civilian noninstitutionalized population.
  • Height and weight are measured in individual survey participants.
  • Between 1976-1980 and 2015-2016, the percentage of children identified as obese showed an increasing trend. In 1976-1980, 5% of children ages 2 to 17 years were obese. This percentage reached a high of 18% in 2015-2016. Between 2001-2002 and 2015-2016, the percentage of children identified as obese remained between 15% and 18%.
    • From 1976-2016, the increasing trend in prevalence of obese children was statistically significant for children overall, and for children of each race/ethnicity and age group. From 1999-2016, the trends were only statistically significant for children overall, ages 11-15 years, ages 16-17 years, and Mexican-American children. (See Table H10 and Table H10a)

  • Survey data are representative of the U.S. civilian noninstitutionalized population.
  • Height and weight are measured in individual survey participants.
  • In 2013-2016, 18% of children ages 2 to 17 years were classified as obese.
  • In 2013-2016, 14% of White non-Hispanic children were obese, compared with 24% of Mexican-American children, 21% of Black non-Hispanic children, and 19% of children of “All Other Races/Ethnicities.”
    • The lower prevalence of obesity among White non-Hispanic children compared with each of the other three groups was statistically significant, as was the difference in prevalence between Mexican-American children and children of “All Other Races/Ethnicities.”
  • Among children overall, the prevalence of obesity was greater in children with family incomes below poverty level than in those above poverty level. However, when accounting for differences by age and sex, children of “All Other Races/Ethnicities” were the only race/ethnicity group to have a statistically significant association between low family income and higher prevalence of obesity.

Background Text

About the Obesity Indicators

Indicators H10 and H11 present information about obesity in children. The data are from a national survey that measures weight and height in a representative sample of the population every two years.

Obesity is the term used to indicate the high range of weight for an individual of given height that is associated with adverse health effects. Body mass index (BMI) is the most common screening measure used to determine whether an individual may be overweight or obese. Children and adolescents greater than or equal to the 95th percentile of BMI-for-age are considered obese.

Obesity has rapidly become a serious public health concern in the United States, and is associated with several adverse health effects in childhood and later in life, including cardiovascular disease risk factors, cancer, psychological stress, asthma, and diabetes. Increased caloric intake and reduced physical activity are likely the major drivers of obesity in children. Researchers are also investigating whether exposures to certain environmental chemicals may play a contributing role in childhood obesity. In addition, multiple reviews of the literature have concluded that several properties of the built environment may be associated with overweight and obesity and/or levels of physical activity in children.

Indicators H10 and H11 present data on obesity in children from the National Health and Nutrition Examination Survey (NHANES).

More information about obesity and Indicators H10 and H11 is provided in the Obesity section of America's Children and the Environment, Third Edition.

Methods

Summary of Methods - Obesity

The National Center for Health Statistics, a division of the Centers for Disease Control and Prevention, conducts the National Health and Nutrition Examination Surveys (NHANES), a series of U.S. national surveys of the health and nutrition status of the noninstitutionalized civilian population. Interviews and physical examinations are conducted with approximately 10,000 people in each two-year year survey cycle. Height and weight are measured for survey participants of all ages.

Indicator H10 uses the NHANES data to present the percentage of children ages 2 to 17 years who were obese. Indicator H11 uses the NHANES data to present the percentage of children ages 2 to 17 years who were obese, stratified by race/ethnicity and family income. Body mass index (BMI) is calculated as an individual's weight in kilograms divided by the square of his or her height in meters. The BMI number is compared with an age- and sex-specific reference population based on the 2000 CDC growth charts. Children and teenagers with BMIs at or above the 95th percentile on the growth charts are classified as obese.

CDC: prevalence of obesity 42.4 percent in 2017 to 2018

(HealthDay)—The prevalence of obesity was 42.4 percent among U.S. adults in 2017 to 2018, according to a February data brief published by the U.S. Centers for Disease Control and Prevention National Center for Health Statistics.

Craig M. Hales, M.D., from the National Center for Health Statistics in Hyattsville, Maryland, and colleagues used data from the National Health and Nutrition Examination Survey to describe the prevalence of obesity and severe obesity among adults by sex, age, and race and Hispanic origin.

The researchers found that the age-adjusted prevalence of obesity was 42.4 percent in adults in 2017 to 2018, with no significant differences seen between men and women or by age. The age-adjusted prevalence of severe obesity was 9.2 percent in adults and was higher in women than men (11.5 versus 6.9 percent). Compared with other race and Hispanic-origin groups, non-Hispanic blacks had the highest prevalence of both obesity and severe obesity. Adults aged 40 to 59 years had the highest prevalence of severe obesity compared with other age groups (11.5 percent). The prevalence of both obesity and severe obesity increased from 1999-2000 to 2017-2018.

"Monitoring the prevalence of obesity and severe obesity is relevant for public health programs that focus on reducing or preventing obesity and its consequences. In the United States, the prevalence of obesity among adults has moved further away from the Healthy People 2020 goal of 30.5 percent," the authors write.

North America

Read the media coverage of the latest U.S. obesity numbers, and you might think the country had turned the corner on the epidemic: “American Obesity Rates Have Hit Plateau, CDC Data Suggest,”(7) and “Good News: Obesity Rates Leveling Off.”(8) But those optimistic headlines tell only part of the story. While U.S. obesity rates have, overall, stayed steady since 2003, they have more than doubled since 1980. They remain worrisomely high-the highest among all of the high-income countries in the world. (1) And obesity takes a heavier toll on some U.S. ethnic and racial groups than others, with rates continuing to rise. (9) A closer look at the U.S. numbers in adults:

  • Roughly two out of three U.S. adults are overweight or obese (69 percent) and one out of three are obese (36 percent). (9)
  • Obesity rates are higher in non-Hispanic Obesity statistics in america, Hispanic, and Mexican American adults than in non-Hispanic White adults. (9)
  • Non-Hispanic Black women have the highest rates of obesity in the U.S.—nearly 59 percent, compared to 44 percent in Mexican American women, 41 percent in Hispanic women, and 33 percent in Non-Hispanic White women. (9)
  • Though overall obesity rates in the U.S. have stayed steady since 2003, obesity rates have continued to climb in men, Non-Hispanic Black women, and Mexican American women. (9)
  • If U.S. trends continue unabated, by 2030, estimates predict that roughly half of all men and women will be obese. (10)

Obesity rates in Canada are not quite as high as they are in the U.S., but Canada has seen similarly-dramatic increases over the past three decades. In 1979, 14 percent of Canadian adults were obese. By 2008, 25 percent of adults were obese, and 62 percent were overweight or obese. (11) Obesity is also more common among Canada’s Aboriginal population than it is among other groups: Surveys from 2007-2008 find obesity rates of 25 percent among Aboriginal groups who live outside of reservations, compared with 17 percent in non-Aboriginal groups. (11)


Central and South America

Theres a dearth of long-term data on obesity rates in Central and South America. Unlike the U.S., where multiple national surveys regularly assess BMI across all age groups, many Central and South American countries tend to field smaller surveyssay, of BMI patterns in city dwellers, or within specific age groupsthat may not give as accurate a picture of obesity trends overall. But taken together, these surveys show that Central and South America have seen steady BMI increases over the past three decades, as well as current obesity rates that rival those of the U.S. and Canada. (1) A closer look at data from the region:

  • Among women, between 1980 and 2008, Finucane and obesity statistics in america estimate that the average BMI in Central Latin America and Southern Latin America increased by 1.3 and 1.4 units per decade. (1) Men in these regions have seen similar increases in obesity, though not quite as steep as those in women. (1)
  • In 2008, more than 30 percent of women in Central and Southern Latin America were obese, according to Finucane’s estimates, and about 25 percent of men in Southern Latin America and 20 percent of men in Central Latin America were obese. (1)
  • In Mexico, a recent report, based on 2006 data collected across Mexico, finds that roughly 30 percent of Mexican adults are obese and 70 percent are overweight or obese, a 12 percent increase since 2000. (12) Three out of four Mexican adults have abdominal obesity, and women have higher rates of obesity and abdominal obesity than men.

There’s evidence that Mexico and other countries in Central and South America are already seeing the burden of obesity shift from the wealthy to the poor. In Mexico, for example, wealthier groups still have higher rates of obesity than lower socioeconomic groups. (12) But the differences in average BMI between Mexico’s more-developed regions in the north and less-developed areas in the south are small. (12) In Brazil, meanwhile, from 1975 to 2003, obesity rates rose far more quickly among people with lower incomes than they did among the wealthiest Brazilians; by 2003, the difference in obesity rates between wealthy and lower-income men had narrowed, and the differences among women had nearly disappeared. (13)


Europe and Central Asia

The European obesity epidemic is far from uniforma reflection, perhaps, of Europes diverse economic and cultural landscape. But its clear that obesity rates are rising across the continent, though not as rapidly or high as they are in the U.S. (1,14)

One challenge to tracking weight trends across Europe is that some countries, especially those of the former Soviet bloc, have only sparse data. But the best available estimates find that over the past 30 years, average BMI in men has been rising a bit more rapidly in Western and Central Europe than in Eastern Europe and Central Asia (0.6, 0.4, 0.2, and 0.2 units per decade, respectively). (1) Average BMI in women stayed relatively stable in Eastern and Central Europe and Central Asia-some of the very few places on the globe to report such a trend-and increased by 0.4 units per decade in Western Europe. (1)

In 2008, men in Western and Central Europe had higher rates of obesity than men in Eastern Europe (20 to 25 percent, versus 15 to 20 percent). (1) In women, obesity rates were higher in Eastern Europe (25 to 30 percent) than in Western Europe (15 to 20 percent) or Central Europe (20 to 25 percent). (1) Not all researchers have found this pattern among Eastern European women, however; having more data from the region would help tease out these trends. (14)

Within Western Europe, there are marked differences in obesity rates from country to country. In 2008, for example, average BMI in the U.K. was among the highest in Western Europe-27.4 in men and 26.9 in women. France and Switzerland, meanwhile, had mean BMIs that were obesity statistics in america lower-25.9 and 26.2 in men, and 24.8 and 24.1 in women. (1) The U.K.’s obesity rates have risen by about a percentage point per year since the mid-1990s, and in 2009, about 25 percent of U.K. adults were obese and 57 percent were overweight. (14)


North Africa and the Middle East

Data are scarce from many countries in Obesity statistics in america Africa and the Middle East, but even so, there’s compelling evidence that obesity rates are on the rise. (1,15) Researchers have taken a closer look at obesity trends in the six Arabian Gulf states (Oman, Bahrain, United Arab Emirates, Saudi Arabia, Qatar, and Kuwait), since these countries have seen tremendous increases in wealth-and weight-since the discovery of oil reserves in the 1960s. (16)

Today, obesity rates in some of the Arab Gulf countries rival or exceed those of the U.S.: In Saudi Arabia, for example, recent surveys have found that 28 percent of men and 44 percent of women are obese, and 66 percent of men and 71 percent of women are overweight or obese. In Kuwait, 36 percent of men and 48 percent of women are obese, while 74 percent of men and 77 percent of women are overweight or obese. (16) Though obesity rates are higher among women in the region than men, they appear to be rising more quickly in men than in women.


Sub-Saharan Africa

Under-nutrition has historically received more public health attention in sub-Saharan Africa than over-nutrition. Yet today, obesity and the chronic diseases that accompany it have become a growing problem across this huge and diverse continent. Some have called it a “silent epidemic,” (17) striking countries that are still struggling with the health and economic burdens of malnutrition, stunting, infectious disease, and high childhood mortality rates.

As in other developing regions, nationally-representative studies of obesity in sub-Saharan Africa are scarce. The studies that are available, though, suggest that obesity rates vary widely from country to country.

For example, in 2008, the average BMI among men in the Democratic Republic of the Congo was 19.9-the lowest in the world. (1) Yet in South Africa, men had an average BMI of 26.9-on par with the average BMIs in Canada (27.5) and the U.S. (28.5). (1)

Some studies in urban settings have found that obesity rates are rising more quickly in the poor than in the rich. (18) More research is needed to give a fuller picture of obesity trends across the continent.


Asia-Pacific Region

Though Asia is home to some of the leanest populations on the globe, (1) there’s no question that obesity has become a serious and growing problem across the region over the past two decades. Obesity rates in “Australasia” (Australia and New Zealand) are not far behind those in the U.S. and Canada-about 25 percent for men and women. (1) In Oceania, the average BMI has climbed by 1.3 units per decade over the past three decades; 15 to 20 percent of men and 25 to 30 percent of women there are obese. (1)

Some countries in South Asia, Southeast Asia, and East Asia have mean BMIs that are among the lowest in the world. In Bangladesh, for example, the estimated mean BMI in 2008 was less than 21, for both men (20.4) and women (20.5). But even Bangladesh and other countries where under-nutrition remains a significant threat-Cambodia, China, India, Nepal, and Vietnam-have seen the prevalence of overweight and obesity in women obesity statistics in america from the 1990s through the mid-2000a, by anywhere from 3.5 to 38.5 percent a year. (4)

Recent trends in China and India are of special concern. Although obesity rates are still fairly low overall, China and India are the most populous nations on the planet-with more than 2.5 billion people, combined-so even small percentage increases in obesity rates translate into millions more cases of chronic disease.

In China, from 1993 to 2009, obesity (defined as BMI of 27.5 or higher) increased from about 3 percent to 11 percent in men and from about 5 percent to 10 percent in women. Abdominal obesity (defined as a waist circumference of 90 centimeters or higher in men, and 80 centimeters or higher in women) also increased during this time period, from 8 percent to 28 percent in men and 28 percent of 46 percent in women. (19) That’s worrisome, since abdominal obesity may carry more serious metabolic consequences than overall obesity.

In India, meanwhile, recent data finds that in 2005, nearly 14 percent of women ages 18 to 49 were overweight or obese, with higher rates among urban women (25 percent) than rural women (8 percent). The rate of overweight and obesity in women, overall, increased by 3.5 percent a year from 1998 to 2005. (4)


The Bottom Line: Turning Around the “Globesity” Epidemic

The worldwide increases in obesity over the past three decades have already led to increases in obesity-related chronic diseases, a trend that threatens healthcare systems, economies, and individual lives. Given the huge costs, both public and personal, of obesity-and how hugely difficult it is to lose weight once someone becomes obese-prevention is key. Slowing the increases in obesity and turning around the epidemic will take large-scale, multifaceted efforts, within individual countries and across the globe, to improve people’s food choices and increase physical activity. These efforts cannot begin in earnest soon enough.

A Global Look at Rising Obesity Rates

Obesity has truly become a worldwide problem, affecting countries rich and poor. So just how many men, women, and children are overweight or obese? It’s a natural question-and a surprisingly hard one for researchers to answer. The east san jose carnegie branch library vast. The data, from some regions, quite spotty. Obesity statistics in america projections from one group differ a bit from the estimates of another. But all point to tremendous increases in global obesity rates over the past three decades-and find that the epidemic shows no signs of abating without dedicated efforts to combat it. (1–5)

One of the most recent and careful global estimates finds that roughly 500 million adults are obese (defined as a body mass index, or BMI, of 30 or obesity statistics in america. (1) That’s almost 10 percent of men and 14 percent of women-and it’s nearly double the rate of obesity in 1980. Nearly 1.5 billion adults were overweight or obese (defined as a BMI of 25 or higher). Data are scarcer on obesity in children, but one global estimate finds that in 2010, 43 million preschool children were overweight or obese, according to the latest international benchmarks set for children, and obesity rates have been steadily rising in preschoolers since the 1990s. (5) If nothing is done to reverse the epidemic, more than 1 billion adults are projected to be obese by 2030. (2)

Not that long ago, obesity was largely a problem of the rich, primarily in wealthy countries. Globalization, though, has made the world wealthier. And as poor countries move up the income scale, and people shift from subsisting on traditional diets to overeating on Western diets, obesity becomes a disease of the poor. The result: Over the past few decades, obesity has quietly become a “pandemic” in developing countries. (4)

One paradox of this so-called “nutrition transition” is that even as obesity rates rise, underweight persists, sometimes within the same household. (6) Low- and middle-income countries often face a dual burden-the infectious diseases that accompany malnutrition and, increasingly, the debilitating chronic diseases linked to obesity and Western lifestyles.

This article gives a enterprise bank and trust overland park ks overview of global obesity trends in adults. Overweight refers to a BMI of 25 to 29.9, obesity, a BMI of 30 or higher. The combined category of “overweight and obese” refers to a BMI of 25 or higher. Since Asians have a higher risk of weight-related diseases at lower BMI levels, some countries in Asia do use lower thresholds for overweight and obesity. But for the purposes of this article, assume that a study has used the standard international adult BMI cut points of 25 for overweight and 30 for obesity, unless otherwise specified.

Here’s a look at obesity in the United States. A person is considered to be obese when he or she reaches a particular body mass index (BMI).

Adults with a Obesity statistics in america of 25 to 29.9 are considered overweight, while adults with a BMI of 30 or more are considered obese.

Obesity can increase the risk of several types of medical issues including diabetes, heart disease, stroke and cancer.

Statistics

Obesity affects 42.4% of American adults over 20.

The annual medical costs for obesity in the United States is $147 billion annually (in 2008 dollars), according to the Centers for Disease Control and Prevention.

The groups with the highest rate of obesity are non-Hispanic blacks (49.6%), Hispanics (44.8%), and non-Hispanic whites (42.2%).

In 2019, no state had an obesity rate below 20%. In Alabama, Arkansas, Indiana, Kansas, Kentucky, Louisiana, Michigan, Mississippi, Oklahoma, South Carolina, Tennessee, and West Virginia, 35% or more of the adults are obese.

A more simplified version of the 1992 Food Guide Pyramid, it recommends portion control and physical exercise as part of a healthy life style to combat obesity statistics in america 2, 2011 –MyPlate replaces the MyPyramid Food Guidance System as the national effort to combat obesity continues. The dietary guidelines are displayed as portions of food on a plate instead of a three-dimensional pyramid.

December 2011 – The Fifth Circuit Court rules that “severe obesity qualifies as a disability” under the Americans With Disabilities Act.

June 26, 2012 – The US Preventive Services Task Force, an independent panel of private-sector experts, recommends all adults be screened for obesity.

February 4, 2019 – According to an analysis released by the American Cancer Association and published in The Lancet Public Health, cancers fueled by obesity are on the rise among young adults in the US and appearing at increasingly younger ages.

June 18, 2019 –A at your bark and call published in The Journal of the American Medical Association finds that obesity rates among low-income preschoolers have declined. The study finds that the prevalence of obesity among 2- to 4-year-olds enrolled in the nation’s Obesity statistics in america, Infants and Children nutrition program fell from 15.9% in 2010 to 13.9% in 2016.

December 18, 2019 – A study published in The New England Journal of Medicine predicts that over half of the US population will be obese within 10 years if the nation does not collectively adopt healthier eating habits. The study also found that one in four Americans will be “severely obese” with a body mass index over 35, which means they will be more than 100 pounds overweight.
