It’s not too late to quit.
A recent study has found that it’s never too late for individuals to quit smoking, even for those in their senior years. According to research published in the American Journal of Preventive Medicine, ceasing smoking at the age of 75 can significantly improve a person’s life expectancy. The study indicates that seniors who continue to smoke will lose an average of over four years of life compared to those who have never smoked.
The research highlights that a 75-year-old smoker has a 14% chance of gaining at least one additional year of life if they quit, while a 65-year-old smoker has a 23% chance. Furthermore, approximately 8% of individuals who stop smoking at 75 could potentially gain four or more years of life compared to those who continue to smoke. The researchers concluded that quitting smoking is the most effective action anyone can take to extend their lifespan, regardless of age.
Lead researcher Thuy Le, an assistant research scientist at the University of Michigan School of Public Health, emphasized that while smoking rates among young adults have decreased significantly in the past decade, the rates among older adults have not changed. The study aimed to demonstrate the benefits of quitting smoking for older adults and to encourage them to take action.
The researchers utilized data from health surveys, census information, and U.S. death registries to create life expectancy tables for three categories: those who have never smoked, those who currently smoke, and those who have quit. The findings revealed that quitting smoking earlier in life can prevent additional losses in life expectancy. For instance, individuals who smoke from the age of 35 could lose an average of nine years, while those who smoke past 45 may lose about seven years.
Even among seniors, quitting smoking can still be advantageous. The study indicated that continuing to smoke after age 65 may cost individuals around six years of life. In contrast, quitting at that age can add at least eight years of life for nearly 10% of those who stop. Researcher Kenneth Warner, dean of the University of Michigan School of Public Health, pointed out that the benefits of quitting smoking extend beyond just younger and middle-aged adults, highlighting its relevance for older adults as well. While the absolute gains may appear modest, they represent a significant portion of an individual’s remaining life expectancy.
