Smoking has a massive negative impact on the biological age

How does Smoking on our age?

Smoking accelerates the aging process. Experts found out now that smokers two decades are in their twenties actually biologically older than they should be.

The scientists from the University of Copenhagen, the University of Oxford and of Insilico Medicine found in their current study that Smoking accelerates the aging process. The doctors published the results of their study in the English-language scientific journal “Scientific Reports”.

What are the results were able to determine, the scientists?

The human body has logical two different ages, a chronological and a biological. The latter refers to how old a Person appears. In their study, the experts analyzed the blood samples from tens of thousands of volunteers, to determine how Smoking can affect biological aging. It was found that smokers often had two times their biological age. The majority of smokers in the age under 30 years was biologically in fact, between 31 and 40 years of age or, in some cases, between 41 and 50 years old. The same Trend was also found for the 31 – to 40-Year-old, in which the age of almost half of the smokers with 41 to 50 years was predicted. Older smokers showed no such effect, possibly because the most Affected had already died, say the researchers. The results were established based on the blood profiles of 149.000 adults, of which 33 percent (49.000) were smokers.

What was studied?

The scientists combined their investigation of an old predictive model with the use of a technique known as Deep Learning, and various biochemical markers of the Participants. To do this, blood sugar levels, iron stores, and urea, excreted in the urine a waste product.

Biological age influences life expectancy

In comparison to non-smokers, smokers showed, regardless of gender, accelerated aging rate up to the age of 55 years, explains the study author, Dr. Polina Mamoshina of the University of Oxford. Previous studies have already shown that the biological age is more useful than the use of a birth date to predict when a Person will die.

How many people are Smoking?

In the UK alone there are an estimated 9.4 million smokers. Smoking is the largest cause of death and disease in the UK die each year more than 120,000 people die as a result. Smoking is around one-fifth of the deaths in the United Kingdom is responsible. In Germany, according to the Epidemiological survey on Addiction in 2015, about 29 percent of adult smokers, which corresponds to about 20 million people. (as)
