Epidemiology of Obesity - The Americas - United States

United States

The United States has the highest obesity rates in the developed world. This is a long-standing phenomenon: already by 1962, 45% of adult Americans were overweight, and 13% of adult Americans were obese; these numbers were already higher than obesity rates observed in most developed countries as late as 2001-02. From 1980 to 2002, obesity rates have doubled, reaching the current rate of 33% of the adult population.

As of 2007, 33% of men and 36% of women are obese. Rates of obesity vary between social groups, with minorities and low-income individuals more likely to be overweight. The rates are as high as 50% among African American women.

Geography is a major factor. The American South has been described alternatively as "Stroke belt", "Obesity belt", or "Diabetes belt", to reflect the fact that all residents of the region have high incidences of these three conditions, compared to people of the same race/ethnicity elsewhere in the country. The lowest obesity rates of major racial/ethnic groups across 50 states are thought to be among non-Hispanic white residents of Colorado and Hawaii, at around 16%. However, these numbers are based on self-reported height and weight data and likely to be underestimated (the bias is so large that, for example, estimates of obesity that rely on self-reported data arrive at the rate of 22% among non-Hispanic white females, whereas studies that involve direct measurement show that the rate is closer to 34%.)

The prevalence of class III obesity (BMI ≥40) has increased the most dramatically, from 1.3% in the late 1970s, to 2.9% in 1988-94, to 4.7% in 2000, to 5.7% in 2008. Among African American women, its prevalence is estimated to be as high as 14%.

The overall rate of obesity began to plateau in the '00s, but severe obesity and obesity in children continued to rise. In January 2010, a study published in the Journal of the American Medical Association found that the obesity rate for American women has remained constant over the last decade, with only small rises amongst men and children.

Obesity is one of the leading health issues in US society, resulting in about 300,000 deaths per year in the United States. About 65 percent of Americans are now considered either overweight or obese. According to National Health and Nutrition Examination Study collected between 1970s and 2004, overweight and obesity prevalence have increased steadily among all groups of Americans over the past three decades.

Famous quotes related to united states:

    What the United States does best is to understand itself. What it does worst is understand others.
    Carlos Fuentes (b. 1928)

    So here they are, the dog-faced soldiers, the regulars, the fifty-cents-a-day professionals riding the outposts of the nation, from Fort Reno to Fort Apache, from Sheridan to Stark. They were all the same. Men in dirty-shirt blue and only a cold page in the history books to mark their passing. But wherever they rode and whatever they fought for, that place became the United States.
    Frank S. Nugent (1908–1965)

    United States! the ages plead,—
    Present and Past in under-song,—
    Go put your creed into your deed,—
    Nor speak with double tongue.
    Ralph Waldo Emerson (1803–1882)

    The popular colleges of the United States are turning out more educated people with less originality and fewer geniuses than any other country.
    Caroline Nichols Churchill (1833–?)

    The United States is just now the oldest country in the world, there always is an oldest country and she is it, it is she who is the mother of the twentieth century civilization. She began to feel herself as it just after the Civil War. And so it is a country the right age to have been born in and the wrong age to live in.
    Gertrude Stein (1874–1946)
