Smoking Makes You Old Before Your Time

Oct. 16 -- WEDNESDAY, Oct. 15 (HealthDay News) -- Everyone knows smoking isn't good for you, but now Finnish researchers report that men who smoke not only die younger but they have a poorer quality of life than those who never smoked.

This deterioration in quality of life continues even after quitting. In fact, heavy smokers typically have the health-related quality of life of someone 10 years older than themselves, the researchers said.

"An especially large negative effect was seen for heavy smokers [more than 20 cigarettes daily], who lost about 10 years of their life expectancy, and those who survived experienced a significant decline in their quality of life," said lead researcher Dr. Arto Y. Strandberg, from the University of Helsinki.

The report was published in the Oct. 13 issue of the Archives of Internal Medicine.

For the study, Strandberg's team collected data on 1,658 men born between 1919 and 1934 and interviewed in 1974. Over 26 years of follow-up, 372 men had died. Men who had never smoked lived an average of 10 years longer than men who smoked more than 20 cigarettes a day, the researchers found.

Non-smokers also scored better on quality-of-life measures, compared with smokers. "Especially significant differences were seen in physical functioning, general health, vitality and bodily pain," Strandberg said. "The impairment of the physical functioning score of smokers was equal to a 10-year age difference in the general population."

Quality of life was worse even among men who stopped smoking. "On the individual level, the bad news is that while beneficial compared to continued smoking, cessation of smoking after midlife could not fully recover the higher risk in mortality and poorer health-related quality of life seen in smokers," Strandberg said.

"Smoking is not only a risk factor for future illness or death, it is present in the smokers' everyday life," Strandberg said. "The earlier one quits, the better; the best option being not to start at all."
