Obesity Affects More Than 4 out of 10 American Adults, Study Reveals Findings stem from a <br />2017-2018 health survey <br />revealed by the CDC. It had over 5,000 participants whose weight <br />was measured by their body mass index (BMI). According to the survey, <br />42 percent were found to be obese. In a 2015-2016 survey, <br />the rate was 40 percent. Government researchers add that almost <br />1 in 10 U.S. adults are severely obese. Around 50 years ago, the severe condition <br />was noted in just 1 in 100 adults. The survey's numbers are small, but obesity is <br />one of the biggest health issues in the U.S. today. George Washington University's Dr. William Dietz says <br />the government needs to take more action. The obesity expert recommends promoting <br />healthier eating options and passing <br />taxes on drinks with sugar.
