Nearly 42 percent of obese adults report having a heart condition, 42 percent say they have high cholesterol, and nearly 60 percent say they suffer from joint pain, according to a new report from the federal government's top health statistics office.

The agency also found:
• One in four U.S. adults was considered obese, and another 5 percent were considered extremely obese.
• Black Americans were more likely than other racial or ethnic groups to be obese (31 percent) or extremely obese (8 percent) as compared with Hispanics, whites and all other races, primarily Asian.
• Adults with a college degree were less likely to be obese (20 percent) or extremely obese (3 percent) compared with high school graduates and those with less than a high school degree.
