Paradox of aging: The older we get, the better we feel?

07.12.2012
Presently, there are about 40 million Americans over the age of 65, with the fastest-growing segment of the population over 80 years old. Traditionally, aging has been viewed as a period of progressive decline in physical, cognitive and psychosocial functioning, and aging is viewed by many as the "number one public health problem" facing Americans today.

But this negative view of aging contrasts with results of a comprehensive study of 1,006 older adults in San Diego by researchers from the University of California, San Diego School of Medicine and Stanford University. Results of the Successful Aging Evaluation (SAGE) study – comprising a 25-minute phone interview, followed by a comprehensive mail-in survey – will be published in the December 7 online issue of the American Journal of Psychiatry.

"While there is a growing public health interest in understanding and promoting successful aging, until now little published research has combined measures of physical health with cognitive and psychological assessments, in a large and randomly selected sample," said principal investigator Dilip V. Jeste, MD, Estelle and Edgar Levi Chair in Aging, Distinguished Professor of Psychiatry and Neurosciences, and director of UC San Diego's Stein Institute for Research on Aging, and the current President of the American Psychiatric Association (which was not involved in this study).

The SAGE study included adults between the ages of 50 and 99 years, with a mean age of just over 77 years. In addition to measures which assessed rates of chronic disease and disability, the survey looked at more subjective criteria such as social engagement and participants' self-assessment of their overall health.

"Sometimes the most relevant outcomes are from the perspective of the subjects themselves," said Jeste.

The study concludes that resilience and depression have significant bearing on how individuals self-rate successful aging, with effects that are comparable to that of physical health. "Even though older age was closely associated with worse physical and cognitive functioning, it was also related to better mental functioning," said co-author Colin Depp, PhD, associate professor of psychiatry at UC San Diego School of Medicine.

After adjusting for age, a higher self-rating of successful aging was associated with higher education, better cognitive function, better perceived physical and mental health, less depression, and greater optimism and resilience.

Participants were asked to rate the extent to which they thought they had "successfully aged," using a 10-point scale and using their own concept of the term. The study found that people with low physical functioning but high resilience, had self-ratings of successful aging similar to those of physical healthy people with low resilience. Likewise, the self-ratings of individuals with low physical functioning but no or minimal depression had scores comparable to those of physically healthy people with moderate to severe depression.

"It was clear to us that, even in the midst of physical or cognitive decline, individuals in our study reported feeling that their well-being had improved with age," Jeste said. This counterintuitive increase in well-being with aging persisted even after accounting for variables like income, education and marriage.

Jeste suggests there's a take-away message for clinicians, which is that an optimistic approach to the care of seniors may help reduce societal ageism. "There is considerable discussion In public forums about the financial drain on the society due to rising costs of healthcare for older adults – what some people disparagingly label the 'silver tsunami.' But, successfully aging older adults can be a great resource for younger generations," he said.

The findings point to an important role for psychiatry in enhancing successful aging in older adults. "Perfect physical health is neither necessary nor sufficient," Jeste said. "There is potential for enhancing successful aging by fostering resilience and treating or preventing depression."

Palmer, PhD, David Rock, BA, and Shahrokh Golshan, PhD, UC San Diego; and Helena C. Kraemer, PhD, professor of biostatistics in psychiatry at Stanford University.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
