All of us know that smoking is injurious for health. But a new study has unveiled something one step ahead. According to a new trial, people who smoke tobacco may be at a higher risk of developing depression and schizophrenia. A team of scientists led by scientists from the University of Bristol in the UK has added weight to growing evidence that smoking can have a negative effect on mental health. Rather than simply analyzing whether the smokers had a genetic predisposition to depression or schizophrenia, the researchers have used genetic data to scrutinize cause-and-effect relationships with smoking. Study’s leading author, Robyn Wootton, said, individuals with mental disorders are often overlooked in our efforts to reduce smoking prevalence, leading to health imbalance.
He added their work reveals there must be every effort to avoid smoking initiation and encourage smoking cessation because of the consequences to mental health as well as physical health. They have analyzed data from more than 400,000 candidates of European ancestry. Notably, the team has used the Mendelian randomization approach to reach a conclusion. The effort includes recognizing genetic variations linked with a trait, such as depression or schizophrenia. After that, they have probed for those variations against an exposure, like smoking, in a group of subjects. It has enabled them to analyze whether this relationship is causal or not.
In the end, the researchers have concluded that while smoking increased the risk of depression and schizophrenia, people with depression and schizophrenia are also more probable to smoke. Even more, the authors have noted that the relationship was quite weaker in those with schizophrenia. Before few months in September, the same team had discovered that smoking raises the risk of bipolar disorder. In the end, smoking is a well-known source of various diseases, including lung cancer, heart diseases, and type 2 diabetes. Reportedly, the habit has resulted in the death of around 78,000 people in England in 2018.
