A group of researchers at the Sahlgrenska Academy has studied the link between overweight and the risk of developing cirrhosis of the liver in middle-aged men. Published in the Scandinavian Journal of Gastroenterology, the study took 855 men aged 50 and followed them for up to 40 years.
None of the men had liver problems at the beginning of the study but during the long follow-up period almost 2% were diagnosed with cirrhosis of the liver. All of the men with this diagnosis were overweight at the beginning of the study, with an average BMI of 28 (a BMI of above 25 is classified as overweight). The average BMI for the men who were not diagnosed with cirrhosis of the liver during the study was below 25. Statistical analysis has demonstrated that both BMI and raised levels of triglycerides – a type of blood fat – constituted risk factors for the development of cirrhosis of the liver. However, the same link could not be statistically proven for alcohol. One explanation for this could be that some men with alcohol problems may have declined to take part in the study.
The results of the study show that both overweight and raised levels of blood fats, which are common in overweight people, significantly increase the risk of men developing cirrhosis of the liver. Given the increasingly discussed and growing problem of overweight in Sweden, there are good grounds for concern that more people will be diagnosed with cirrhosis of the liver.
“A liver that has been ill and weakened as a result of overweight can take less of a load,” says Kaczynski. “We can therefore speculate that cirrhosis of the liver will develop more quickly in people who drink too much alcohol if they are overweight. Our study does not offer any evidence for this, but this kind of speculation is well founded.”For more information, please contact:

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
