Obesity Statistics

Most Popular Obesity Statistic

According to a study in the Journal of the American Medical Association (JAMA), 65% of American adults are overweight [1].   Check the study yourself!

  • 65% of adults were overweight
  • 30% were considered OBESE
  • 5% were considered extremely OBESE
  • 16% of kids were overweight

Obesity Statistics Even Worse

Since the study above was published, obesity statistics got worse, according to the CDC [2]:

  • 34% of American adults are OBESE
  • 40% of men aged 40-59 are OBESE
  • 61% of non-Hispanic black women 60 and older are OBESE

These are just some of the statistics I was amazed to read on the CDC’s site.  I don’t like it anymore than you do.

Obesity Statistics in Children

The following graph shows percentage of children who are overweight over time.  It is amazing to me how the percentage of overweight children has quadrupled in the last 30 years!  The definition of “overweight” was: “children with BMI values at or above the 95th percentile of the sex-specific BMI growth charts.” [3]

Data for this graph came from the CDC’s site [3].
