Scientists find link between smoking, depression and schizophrenia

British researchers found causal relationship between smoking and smoking and mental health impairment from genetic variations The globe 06 / 11 / 2019 – 10: 46 / Updated 06/11/2019 – 11: 19 Smoking may lead to the development of depression and schizophrenia, British scientists say Photo: Ana Branco / Agência O Globo RIO – Scientists at the University of Bristol in UK, found evidence of the link between smoking and the development of diseases such as depression and schizophrenia. The news was published on Wednesday in the British journal Psychological Medicine. Although the smoking habit recurrent among people with mental disorders, the researchers point out, a cause-and-effect relationship was first identified.

The evaluation was made using a method called Mendelian randomization, which takes into account genetic variations to trace causal effects. It also allows you to reduce the range of factors that may influence the smoking. In addition, the researchers also found evidence that depression and schizofrein also increase the likelihood that an individual will start smoking. The Bristol scientists point out that another study, conducted by the University of Amsterdam in partnership with the British Journal of Psychiatry, had already pointed to the increased incidence of bipolarity among smokers.

The authors state that this detail is crucial, especially in the context of the increased use of electronic cigarettes. According to Robyn Wootton, senior researcher at the Bristol School of Psychological Sciences who led the work, people suffering from mental health problems are usually left behind in the fight against smoking, which opens the door to inequality in health care. In 2016, the British government issued a recommendation to the psychiatric institutions that smoking should be abolished on its premises by 2018. For Wootton, the finding reinforces the need for even wider deployment of this policy. Marcus Munafò, a professor of psychiatric biology who also signs the study, says the data highlight something important to science: the fact that genetic research can be as revealing as the influences of the social environment. Important factor for research on smoking, but also alcohol consumption.
