Lifestyle affects life expectancy more than genetics

08.02.2011
How long your parents lived does not affect how long you will live. Instead it is how you live your life that determines how old you will get, reveals research from the University of Gothenburg recently published in the Journal of Internal Medicine.

It is often assumed that people with parents who lived to be very old are more likely to live to a grand old age themselves.

“But that’s just not true – our study shows that hereditary factors don’t play a major role and that lifestyle has the biggest impact,” says professor emeritus Lars Wilhelmsen, referring to the 1913 Men study that formed the basis of the current research.

Those who did not smoke, consumed moderate amounts of coffee and had a good socio-economic status at the age of 50 (measured in terms of housing costs), as well as good physical working capacity at the age of 54 and low cholesterol at 50 had the greatest chance of celebrating their 90th birthday.

“We’re breaking new ground here,” says Wilhelmsen. “Many of these factors have previously been identified as playing a role in cardiovascular disease, but here we are showing for the first time that they are important for survival in general.”

He believes that it is significant that the research illustrates so clearly that we do not “inherit” mortality to any great extent, but instead that it is the sum of our own habits that has the biggest impact.

“The study clearly shows that we can influence several of the factors that decide how old we get,” says Wilhelmsen. “This is positive not only for the individual, but also for society as it doesn’t entail any major drug costs.”

The study has been published in the Journal of Internal Medicine.

The study of men born in 1913
The 1913 Men epidemiological study started up in 1963. A third of all male 50-year-olds in Gothenburg were called for a check-up that focused on cardiovascular health. Every ten years since, a new group of 50-year-olds has been called in and those who were already taking part in the study have been given another check-up. This has enabled researchers to follow the development of illnesses in a specific age group, and to compare the health of 50-year-olds in 2003 with that of 50-year-olds in 1963, for example. Women have also been included in the study since 2003. Several variables have been studied over the years, including BMI, smoking habits, cholesterol, exercise habits and blood pressure.

The men born in 1913 were examined when they were 50, 54, 60, 67, 75 and 80. Of the 855 men who took part in the study from the start, 111 (13%) were still alive at the age of 90.

Over the years the material has generated many research articles and doctoral theses. An interesting result came in 2008 when researchers were able to show that the drop in the number of smokers, combined with lower cholesterol levels and lower blood pressure, between 1963 and 2003 could offer an explanation for the marked downturn in the number of heart attacks during this 40-year period.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
