Results from a new pilot study funded by the Austrian Science Fund FWF found that consuming alcohol could influence bone formation in young people, resulting in long-term consequences.
If you drink alcohol regularly and over a long period of time, you will not only damage your organs but also do harm to your bones. Alcoholism has been proven to constitute a risk factor for osteoporosis, as it leads to a decline in bone mass and a general deterioration of bone metabolism.
The study, conducted at the Medical University of Vienna, suggests that excessive consumption of alcohol, or binge drinking, has a negative impact on bone tissue in young people. Anyone who consumes alcohol regularly and in excess during their youth could be doing lasting damage to their bones even before the peak of bone mass is reached at around the age of 20.
At the University of Veterinary Medicine, Vienna – the study’s cooperation partner – young pigs were given a mixture of alcohol and apple juice commensurate with their body weight twice a week. A second control group received only apple juice. The research team led by Peter Pietschmann took blood serum samples at different points in time and determined various markers for bone and muscle metabolism. In a second step, the researchers examined the pigs’ bones two months after the experiment had begun and identified changes caused by alcohol. €œOur results may suggest that bone formation processes are reduced,€ said Peter Pietschmann. For their tests, the scientists took bone samples from body parts susceptible to fractures. They checked the samples under a microscope and by means of microcomputed tomography in order to analyse bone structure, renewal processes and the bone cell count. The investigations also included blood sampling and histological examinations at the Institute for Pathophysiology and Allergy Research (IPA) at the Medical University of Vienna. In addition to changes in the bones, the blood samples also showed diminished levels of phosphorus and calcium, which is a typical change that also occurs in humans as a result of alcohol consumption. The findings give Pietschmann reason to believe that binge drinking also has long-term effects on bone function in humans: €œIf we find further evidence for our hypothesis that bone formation is diminished by drinking, this means that the bone mass of young people who have a drinking problem will not be able to develop normally.€ This might lead to an elevated risk of osteoporosis occurring in later life. Further research is now planned to build on the existing findings. Pietschmann is also interested in establishing connections between bone metabolism and the immune system.
