Obesity in the U.S.
There has been an alarming increase in the rate of obesity in children and adults since the 1970s.
Even though estimates reveal that the overall obesity rate has declined in some groups, it cannot be denied that obesity is still highly prevalent and among the leading health problems in the US.
Furthermore, it is more worrisome that severe obesity is an increasing issue among children and adults. Significant disparities are found due to gender, race-ethnicity, age, socioeconomic status, and geographic region
Adult Obesity in the U.S.
According to the latest data, nearly 39.6% of adults in the US are obese, while 31.6% are overweight, and 7.7% are severely obese.
It is seen that the obesity rate is high in Hispanic and Black women and Hispanic men.
Furthermore, people in the south and Midwest and Nonmetropolitan countries are more inclined towards obesity. Obesity increases with age.
As per recent national data, about 50.6% of Hispanic women and 54.8% of black women are obese. In comparison, around 38% of white women face the issue.
The obesity rate in white men is 37.9% compared to that of Hispanic men, which is 43.1% and Black men, which is 36.9%.
It is also seen that the rate of obesity in Asian men and women is lower compared to that of other racial-ethnic group wherein 14.8% of Asian women are obese and 10.1% Asian men.
You can take a look at the data on adult obesity derived from the National Health and Nutrition Examination survey.
Further analyses reveal that severe obesity is more prevalent among women than men, as nearly 9.9% of women have the problem compared to 5.5% of men. This is particularly true for Black women, where the rate of severe obesity is nearly double to that of white and Hispanic women.
