Ben-Gurion U of the Negev study demonstrates link between appetite and elderly mortality

13.05.2009
A new study by a Ben-Gurion University of the Negev (BGU) researcher reveals a linkage between elderly people's appetite and mortality rates, with those who report impaired appetite more likely to die sooner.

The study, published in the May issue of the Journal of Nutrition, Health & Aging, demonstrated a link between the Daily Activity Energy Expenditure (DAEE-- an accurate measurement of total physical activity), appetite and mortality among well functioning community-dwelling adults. Information on an elderly patient's eating habits may be important for health providers regarding risk for patient deterioration and mortality.

"These findings are important because they show how subjective appetite measurement can predict death, even when adjusting for health and many other variables," said Dr. Danit Shahar, a researcher with BGU's S. Daniel Abraham International Center for Health and Nutrition and Department of Epidemiology. "Past studies failed to show an association with survival. It was thought that decreased appetite may be an indicator or a result to other health problems, and that malnutrition, rather than low appetite was associated with mortality."

"Dietary Factors in Relation to Daily Activity Energy Expenditure and Mortality among Older Adults" analyzes data from the Health, Aging and Body Composition (Health ABC) study to demonstrate that higher DAEE is strongly associated with increased appetite, resulting in lower risk of mortality in healthy older adults. Using 298 older participants (ages 70-82 years) in the Health ABC study, researchers analyzed DAEE and dietary factors, including self-reported appetite, enjoyment of eating and intake assessed by the Block Food Frequency Questionnaire (FFQ) and Healthy Eating Index (HEI).

Participants who reported improved appetite were at lower risk for mortality. Similarly, participants who reported good appetite at baseline had a low risk for mortality. The results remained significant taking into account health status, physical activity, demographic and nutritional indices. Follow up was nine years.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
