So let's put this in perspective. Most online sizing charts said going up one pant size means gaining an inch around the waist. So for one increase in pant size, the noise pollution has to reach more than 100 decibels.
Considering a power saw operates at 110 decibels, that'd have to be some intense traffic. But any gain can be significant.
This is an even bigger issue for women, as the National Institutes of Health has cited excess weight around the hips as a risk indicator for cancer and heart disease.
As some researchers are noting, though, this is the first study of its kind, and reviews will be needed before the finding is considered definitive.
