Four health behaviours can add fourteen extra years of life

08.01.2008
People who adopt four healthy behaviours – not smoking; taking exercise; moderate alcohol intake; and eating five servings of fruit and vegetables a day – live on average an additional fourteen years of life compared with people who adopt none of these behaviours, according to a study published in the open access journal PLoS Medicine.

Rather than focusing on how an individual factor is related to health, the study calculates the combined impact of these four simply-defined forms of behaviour. The results suggest that several small changes in lifestyle could have a marked impact on the health of populations.

There is overwhelming evidence showing that lifestyles such as smoking, diet and physical activity influence health and longevity but there is little information about their combined impact. Furthermore the huge amount of information provided by these studies and the varying definitions of a health behaviour that these studies use can often make them confusing for public health professionals and for the general public. For example: small amounts of alcohol appear to be related to lower risk of cardiovascular disease health but what is the overall impact on longevity ?

In order to examine the combined impact of changes in lifestyle, Kay-Tee Khaw and colleagues from the University of Cambridge and the Medical Research Council used a health behaviour score that is easy to understand in order to assess the participants in the study (who were from Norfolk, United Kingdom). Between 1993 and 1997, 20,000 men and women between the ages of 45 and 79, none of whom had known cancer or heart or circulatory disease, completed a questionnaire that resulted in a score between 0 and 4. A point was awarded for each of the following: not currently smoking; not being physically inactive (physical inactivity was defined as having a sedentary job and not doing any recreational exercise); a moderate alcohol intake of 1-14 units a week (a unit is half a pint of beer or a glass of wine); and a blood vitamin C level consistent with eating five servings of fruit or vegetables a day. Deaths among the participants were recorded until 2006.

After factoring in age, the results showed that over an average period of eleven years people with a score of 0 – i.e. those who did not undertake any of these healthy forms of behaviour – were four times more likely to have died than those who had scored 4 in the questionnaire. Furthermore, the researchers calculate that a person who has a health score of 0 has the same risk of dying as someone 14 years older who had scored 4 in the questionnaire (i.e. someone engaging in all four healthy forms of behaviour). This was independent of social class and body mass index. The study forms part of the European Prospective Investigation into Cancer and Nutrition (EPIC), conducted across ten European countries, the largest study of diet and health ever undertaken.

As a related editorial discusses, individuals in isolation often cannot make the lifestyle changes they want and a set of complex processes affect how research is translated into effective public health policy.

The results of this study need to be confirmed in other populations and an analysis of how the combined health behaviours affect quality of life is also needed. Nevertheless the results of the study strongly suggest that these four achievable lifestyle changes could have a marked improvement on the health of middle-aged and older people, which is particularly important given the ageing population in the UK and other European countries.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
