The study, conducted by Martha L. Daviglus, M.D., professor of preventive medicine, and colleagues at Northwestern University Feinberg School of Medicine, examined the impact of body mass index (BMI) earlier in life on Medicare expenditures for treating cardiovascular-related disease, diabetes-related disease and total average annual Medicare charges, as well as cumulative Medicare charges, from age 65 to death or to age 83.
The impact of BMI in young adulthood and middle age on future Medicare expenditures from age 65 to death or to attainment of advanced age has not previously been addressed.
Medicare data from 1984 to 2002 were linked with data from the Chicago Heart Association Detection Project in Industry (which enrolled participants from 1967 to 1973) for approximately 9,980 men and about 7,620 women who were free of coronary heart disease, diabetes and major electrocardiographic abnormalities, were not underweight and were Medicare-eligible for at least two years during 1984 to 2002. Participants were classified by their baseline BMI.
The researchers found that average annual and cumulative Medicare charges were significantly higher by higher BMI for both men and women. Total average annual charges for non-overweight, overweight, obese and severely obese women were, respectively, about $6,225; $7,650, $9,610 and $12,340.
Corresponding total cumulative charges also were significantly higher up to almost $175,000 for severely obese women.
