Do psychiatric diseases increase risk of heart disease and diabetes? Study suggests so!

Oxford [England], January 29 (ANI): The impact of mental health on one's physical health is something that is now being realized by people more and more, as a result of more open discussions on mental health. A new study has revealed that mental health has an impact on chronic diseases too.
According to the study, published in 'PLOS' Medicine, led by Seena Fazel of the University of Oxford, UK, and colleagues, among patients with chronic, non-communicable diseases, the risk of death is more than doubled if they also have a psychiatric comorbidity.
Non-communicable diseases such as diabetes and heart disease are a global public health challenge accounting for an estimated 40 million excess deaths annually. In the new study, researchers used national registers in Sweden to investigate more than 1 million patients born between 1932 and 1995 who had diagnoses of chronic lung disease, cardiovascular disease, and diabetes. More than a quarter (25-32 per cent) of people in the analysis had a co-occurring lifetime diagnosis of any psychiatric disorder.
Within 5 years of diagnosis, 7 per cent (range 7.4 per cent-10.8 per cent; P<0.001) of the people included in the study had died from any cause and 0.3 per cent (0.3 per cent-0.3 per cent; P<0.001) had died from suicide. Comorbid psychiatric disorders were associated with higher all-cause mortality (15.4 per cent-21.1 per cent) when compared to those without such conditions (5.5 per cent-9.1 per cent).
When the researchers compared each patient with an unaffected sibling, to account for familial risk factors, psychiatric comorbidity remained consistently associated with elevated rates of premature mortality and suicide (adjusted HR range: aHRCL=7.2 [95 per cent CI: 6.8-7.7; P<0.001] to aHRCV =8.9 [95 per cent CI: 8.5-9.4; P<0.001]).
Risks ranged by psychiatric diagnosis; for instance, mortality risks were elevated by 8.3-9.9 times in those with comorbid substance use disorder compared to unaffected siblings, and by 5.3-7.4 times in those with comorbid depression.
One limitation of the study, was that the use of population-based registries to identify patients meant that psychiatric comorbidities were diagnosed in specialty care settings and that undiagnosed individuals and those with less severe psychiatric illness could be missed.
"Improving assessment, treatment, and follow-up of people with comorbid psychiatric disorders may reduce the risk of mortality in people with chronic non-communicable diseases," the authors said.
"We used electronic health records to investigate over 1 million patients diagnosed with chronic lung diseases, cardiovascular diseases, and diabetes," Fazel added.
"More than 7 per cent of the patients died of any cause within five years and 0.3 per cent died from suicide -- risks that were more than doubled in patients with psychiatric comorbidities compared to those without such comorbidities," Fazel concluded. (ANI)
