Women who are better educated and live in households that are middle-income or above are less likely to be obese than women who are less educated and live in the lowest income households, new government research shows.
Among men, there is not a statistically significant (26) in obesity based on income and very (27) difference based on education, the data show.
(28) , about one in three U.S. adults-almost 73 million people-are obese, which is (29) 30 or more pounds over a (30) weight. Extra weight raises the (31) of diabetes, heart disease, some types of cancer and other (32) .

·33% of men who live in households with an annual income of $77,000 or more for a family of four are obese, (40) 29% of men who live in households with an annual income below $29,000 for a family of four are obese. This difference is not considered statistically (41) .
The analysis is based on (42) from the National Health and Nutrition Examination Survey, which is considered the gold (43) for evaluating obesity because it is a(an) (44) survey of people whose weight and height are actually (45) rather than being self-reported.
