Adverse Effect of Heavier Smoking on Facial Aging

Smoker’s Face– a condition where smokers look older than they are, is just one of many negative effects caused by heavy tobacco usage, researchers have warned.

“We searched across thousands of traits to identify those that may be affected by how heavily someone smokes. As well as identifying several known adverse effects such as on lung health, we also identified an adverse effect of heavier smoking on facial aging,” said study author Louise Millard from the University of Bristol in UK.

According to the study, published in the journal PLOS Genetics, some people carry one or two copies of a genetic variant that is associated with heavier tobacco use.

To simultaneously identify these two types of effects, the researchers used a novel combination of two data analysis approaches and applied them using data from people in the UK Biobank.

We searched across thousands of traits to identify those that may be affected by how heavily someone smokes.

They separated people into two groups. The first contained people who had never smoked, and the second included current and former smokers.

The analysis searched across 18,000 traits and apart from the new finding of more rapid facial aging, also identified several previously reported effects of smoking, confirming the method’s effectiveness.

The known effects of smoking that the analysis identified included worse lung function, and higher risk of chronic obstructive pulmonary disease (COPD) and skin cancer.

Besides emphasising smoking’s many dangers, the study also serves as proof of principle that these data analysis tools can be used to identify effects of other exposures of interest, such as alcohol intake. (IANS)

Study says that smoking cigarettes can increase the risk of developing depression

If you are a regular smoker, quit now as researchers have found that tobacco smoking may increase your risk of developing depression and schizophrenia.

“Individuals with mental illness are often overlooked in our efforts to reduce smoking prevalence, leading to health inequalities,” said study lead author Robyn Wootton from the University of Bristol.

“Our work shows that we should be making every effort to prevent smoking initiation and encourage smoking cessation because of the consequences to mental health as well as physical health,” Wootton added.

For the study, published in the journal Psychological Medicine, the research team used UK Biobank data from 462,690 individuals of European ancestry, comprising 8 per cent current smokers and 22 per cent former smokers.

The team applied an analytic approach called Mendelian randomisation, which uses genetic variants associated with an exposure (e.g. smoking) to support stronger conclusions about cause-and-effect relationships.

“The increasing availability of genetic data in large studies, together with the identification of genetic variants associated with a range of behaviours and health outcomes, is transforming our ability to use techniques such as Mendelian randomisation to understand causal pathways,” said study senior author Marcus Munafò.

“What this shows is that genetic studies can tell us as much about environmental influences – in this case the effects of smoking on mental health – as about underlying biology,” Munafo added.

The research also suggests that smoking can have adverse effects on mental health.This new evidence adds further weight to support the implementation of smoke-free policies.

Not only is there evidence that smoking can be detrimental to mental health, but much of the excess mortality associated with depression is due to smoking, the study added. (IANS)
