Obesity in middle age may drastically raise future medicare expenditures

08.12.2004


Overweight and obesity in young adulthood and middle age may have devastating effects on future Medicare expenditures, particularly given the continued and alarming increase in prevalence of obesity in the United States during recent decades, according to a study published in the Dec. 8 issue of The Journal of the American Medical Association.



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. In non-overweight, overweight, obese and severely obese men, total average annual charges were, respectively, about $7,200, $8,390, $10,130 and $13,675.

Corresponding total cumulative charges were also were significantly higher – up to almost $177,000 for severely obese men. Approximately 130 million U.S. adults are overweight or obese. At the same time, the U.S. population is aging rapidly. Data from the National Center for Health Statistics indicate that the proportion of U.S. adults aged 65 and older will increase from about 12 percent currently to 20 percent by 2050.

"With current trends of increasing overweight and obesity afflicting all age groups, urgent preventive measures are required not only to lessen the burden of disease and disability associated with excess weight but also to contain future health care costs incurred by the aging population," Daviglus said.

"Public health efforts need to include comprehensive national strategies and resources for primary prevention of weight gain from early life on, with the goal to contain and end the obesity epidemic and reduce health care costs among older persons," Daviglus said.

Colloborating with Daviglus on this study were Kiang Liu, professor of preventive medicine; Lijing L. Yan; Amber Pirzada, M.D.; Larry Manheim; Daniel B. Garside; Renwei Wang, M.D.; Alan R. Dyer; Philip Greenland M.D., Harry W. Dingman Professor of Cardiology and chair of preventive medicine; and Jeremiah Stamler, M.D., emeritus professor of preventive medicine, Feinberg School; and Willard G. Manning, University of Chicago.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
