Exposure to noise from traffic, trains and planes may be linked to a burgeoning belly, Swedish researchers report.

The increased risk of a larger waist rose with the number of sources of noise someone was exposed to at the same time — from 25 percent for those exposed to only one source to nearly double for those exposed to all three sources, the scientists added.

“Long-term exposure to traffic noise may affect our metabolism and lead to abdominal obesity,” said lead researcher Charlotta Eriksson, from the Institute of Environmental Medicine at the Karolinska Institute in Stockholm.
