What's the Best Age to Stop Smoking? Study Offers Clue
-
Smokers who quit before age 35 showed a complete "reversal of risk" when compared to people who never smoked, according to a new national study. Researchers also quantified the benefit of quitting for those older than 35. The added risk of death associated with smoking was reduced by:
90% for those who quit before age 45
66% for those who quit at ages 45 to 64 -
@sagnika Published Monday in JAMA Network Open, the study involved 551,388 U.S. participants using information collected by the CDC from 1997 to 2018. Researchers collected data for specific causes of death of participants through the end of 2019. The results echo past findings but also established whether demographic factors such as a smoker's race and gender impact the benefits of quitting. (In many areas of health research, a person's race or gender is associated with varying risks.)
