Death – Obituary – Accident and Crime News : New Study Shows Significant Reduction in Mortality Rates for Former Smokers

A recent study conducted by researchers at Stanford University‚Äôs School of Medicine has revealed that the risk of death related to cancer and respiratory causes is less than 50% for individuals who have quit smoking compared to those who continue to smoke. The findings also indicate that after 20-29 years of smoking cessation, former smokers’ cardiovascular mortality rates are similar to those of individuals who have never smoked.

The study, which utilized medical data from the National Health Interview Survey, a representative sample of the US population, shed light on the fact that despite growing awareness about the dangers of smoking, there are still approximately 28 million active smokers in the country today.

Led by Blake Thomson, DPhil, the researchers aimed to determine the specific timeframe in which the mortality benefits of smoking cessation become apparent. They analyzed data from the National Health Interview Survey from 1997-2018, connected it to the National Death Index, and compared current smokers, former smokers who had quit at different intervals, and “never smokers” in terms of cause-specific deaths related to cancer, cardiovascular, and respiratory issues.

The study included 438,015 adult individuals, with a mean age of 47, and found a total of 10,935 cancer, 11,860 cardiovascular, and 2,060 respiratory deaths during the 5 million person-years of follow-up.

The researchers discovered that current smokers had significantly higher death rate ratios (RRs) for cancer (3.38), cardiovascular (2.30), and respiratory death (13.31) compared to never smokers. However, former smokers experienced a substantial reduction in risk during the first decade after quitting, with reductions of 53%, 64%, and 57% for cancer, cardiovascular, and respiratory deaths, respectively. Moreover, after 20-29 years of smoking cessation, former smokers showed minimal excess cardiovascular mortality, and after 30 years, they had avoided 93%, 100%, and 97% of excess cancer, cardiovascular, and respiratory deaths associated with continued smoking.

The study’s findings highlight the long-term benefits of smoking cessation and emphasize the importance of sustained quitting to achieve mortality rates similar to those of individuals who have never smoked. The researchers noted that their analysis accounted for various factors such as sex, age, education levels, race, ethnicity, and alcohol consumption to ensure the accuracy of the results.

“Quantifying excess cause-specific mortality among former smokers by years since quitting may inform clinical decision-making and screening programs,” wrote Thomson and colleagues.

These findings provide further evidence of the hazards of smoking and the potential benefits of quitting. The researchers hope that their study will encourage smokers to consider quitting and provide healthcare professionals with valuable information to support smoking cessation efforts.
