Hawaii was one of eight states whose diabetes rates increased last year, according to a report released today by Trust for America’s Health and the Robert Wood Johnson Foundation.

Colorado was the only state with an obesity rate lower than Hawaii in 2014. Last year, about 22 percent of Aloha State residents were obese, which is more than double the rate in 1990, according to The State of Obesity report.

The report analyzed obesity rates, prevention policies and other obesity-related conditions, such as hypertension and diabetes.

The report found that Hawaii could have 359,114 cases of heart disease in 2030, up from 78,240 cases reported in 2010. Similarly, if the state continues at the present rate, approximately 50,000 more adults could have diabetes within the next 15 years.

Obesity is one of the biggest health-care cost drivers in the U.S. — adding up to billions of dollars in preventable spending each year, according to the report. If the nation’s obesity epidemic isn’t addressed, members of America’s current generation of young people could be the first in history to live shorter lives than their parents, the report said.

Nationally, more than 30 percent of adults and nearly 17 percent of children and teens are obese, which usually means a person’s weight is 20 percent heavier than normal, according to the report. Meanwhile, approximately 68 percent of adults are overweight, which means they’re 10 to 20 percent heavier than normal.

Three states – Arkansas, West Virginia and Mississippi – now have obesity rates over 35 percent. Of the 25 states with the highest obesity rates, 23 were in the Midwest and the South.
