The results are being published in the latest issue of the European Heart Journal.
"Atrial fibrillation proved to be significantly more common both among those men who were big during their youth, as well as among those who gained a considerable amount of weight later on in life," says Annika Rosengren, Professor of Medicine at the Sahlgrenska Academy.
The study reveals that the risk of atrial fibrillation increases linearly with both body size and weight gain. The larger the men were in their 20s and the more weight they gained during their life, the greater the risk.The fact that the men were big in their youth does not mean that they were obese. Obesity in young men was extremely unusual during the 1930s and 40s, and these big men were quite simply tall and well-built.
"Since both weight and height are increasing among young people, it's quite likely that atrial fibrillation will become more common when today's young men reach their 60s and 70s, particularly if the tendency to put on several kilos later on in life continues," says Annika Rosengren.
