Less education, income linked to obesity in women, not men

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) .
"There is a relationship between obesity and income, but it’s not a (33) story," says Cynthia Ogden, an epidemiologist with the National Center for Health Statistics, part of the Centers for Disease Control and Prevention.
"When looking at these two (34) of socioeconomic status-income and education-their (35) is greater on women than men," she says.
Jennifer Lovejoy, president of the Obesity Society, says that (36) -income women may be more likely to become obese because of environmental (37) such as lack of access to safe places to do physical activity and easy access to fast food.
Among the findings:
·29% of women who live in households with an annual income of $77,000 or more for a family of four are obese in opposition (38) 42% of women who live in households with an annual income below $29,000 for a family of four.
·23% of women with a college degree are obese, significantly less than the 42% of women with (39) than a high school education.
·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.
