Smoking significantly increases your biological age, warns study

Smokers in their twenties are biologically two decades older than they should be, according to the first study of its kind. Researchers now warn the 'fascinating evidence' proves the notoriously bad habit accelerates the ageing process.  The human body has two different ages - chronological and biological. The latter refers to how old a person seems

Smokers are often portrayed as older looking and haggard with facial features that are associated with worn leather; such depictions most often carry over into reality. Regardless of how smokers are portrayed what cannot be denied is the association between smoking, cancer, and cardiovascular disease being very strong.

Unfortunately, however, the connection between smoking and biological ageing has been less clear. Yet, a new study from an international team of investigators led by scientists at Insilico Medicine may change how smoking is evaluated at the biochemical level.

Insilico Medicine, one of the leaders in artificial intelligence for drug discovery, biomarker development, digital medicine, and ageing research, announced the publication of a new collaborative research paper titled ‘Blood Biochemistry Analysis to Detect Smoking Status and Quantify Accelerated Aging in Smokers’ in Scientific Reports.

Smoking has long been proven to negatively affect people’s overall health in multiple ways. The study by Insilico scientists set out to determine biological age differences between smokers and non-smokers, and to evaluate the impact of smoking using blood biochemistry and recent advances in artificial intelligence.

By employing age-prediction models developed by supervised deep learning techniques, the study analysed a number of biochemical markers, including measures based on glycated haemoglobin, urea, fasting glucose and ferritin.

According to study’s results, smokers demonstrated a higher aging ratio, and both male and female smokers were predicted to be twice as old as their chronological age as compared to non-smokers.

The results were carried out based on the blood profiles of 149,000 adults

Other findings suggested that deep learning analysis of routine blood tests could replace the current unreliable method of self-reporting of smoking status and evaluate the influence that other lifestyle and environmental factors have on ageing.

“I am pleased to be part of the research study, which provides fascinating scientific evidence that smoking is likely to accelerate ageing. Smoking is a real problem that destroys people’s health, causes premature deaths, and is often the cause of many serious diseases. We applied artificial intelligence to prove that smoking significantly increases your biological age,” said Polina Mamoshina, a senior research scientist at Insilico Medicine.
