Weight gain leads to reduced respiratory function

Gaining one pound a year as a person ages may significantly reduce respiratory function. A weight gain of nine pounds may reduce respiratory capacity one-half of that which would be produced by
cigarette smoking.

Smoking, aging, overweight, and dust exposure are all known to cause a reduction in lung function, but until this study, the significance of weight gain was not apparent. (American Journal of Respiratory and Critical Care Medicine 153:1907-13, 1996) Copyright 1996 Phylis Austin
