Interrelationship of smoking, paraoxonase activity, and leisure time physical activity: a population-based study.
We determined the effect of smoking on PON1 activity levels in a population-based sample of 1380 subjects and examined the possibility of regular physical activity modulating the effect of cigarette smoking on PON1 activity levels at a population level. ⋯ Smoking appears to have a deleterious effect on PON1 activity levels. Being physically active clearly attenuates this effect.
