Four-Cohort Meta-Analysis-age

Scientists looked at information from different studies to learn about smoking and its effects on people’s lives. They used data from four big studies in the US, Canada, Norway, and the UK. They collected information about people’s health and followed them for 15 years.

The first two studies included adults aged 20-79 in the US and Canada, between 1997 and 2018. In Norway, they combined three studies from 1974 to 2003 with people aged 25-79. The fourth study in the UK invited adults aged 40-73 to participate. In total, they studied 1.48 million adults from rich countries.

They used a special math model to analyze the data and considered factors like age, education, alcohol use, and obesity. They found that smoking increased the chances of dying early.

At the end of the study, they looked at 122,697 deaths. They discovered that smokers had a higher risk of dying early compared to non-smokers. The study found that smoking could shorten the lives of women by 12 years and men by 13 years. Specifically, smoking increased the risk of respiratory diseases, cardiovascular diseases, and cancers.

But, there’s good news. If people quit smoking, their risk of dying early goes down. The study showed that quitting smoking before the age of 40 could bring the risk back to the level of non-smokers after just three years. The longer people stayed smoke-free, the better their chances of living longer.

Even if people quit after the age of 40, the study showed it still made a big difference. Quitting for more than 10 years reduced the risk of early death by almost 100% for women and 96% for men.

The study also found that the earlier people quit smoking, the more years of life they could gain. Quitting before 40 could add 12 years to life, while quitting between 40 and 49 added 6 years. Even if people quit between 50 and 59, they could gain 2.5 years.

In conclusion, quitting smoking is good for your health no matter when you do it. The earlier, the better, but it’s never too late to make a positive change. Even a few years without smoking can make a big difference in how long you live. So, if you smoke, consider quitting for a healthier and longer life.
