The researchers found that more than a third (35.3%) of children and adolescents reported at least one mental disorder and one chronic physical disease. The strongest correlation was found between affective disorders (e.g. depression) and diseases of the digestive system.
Adolescents with anxiety disorders were also suffering above-average from arthritis, heart disease and diseases of the digestive system. Similar correlations occurred between eating disorders and seizures (epilepsy). Factors such as age, gender or socioeconomic status of the adolescents did not account for these associations.
Due to the cross-sectional design of the study, the results do not show if and how mental disorders and physical disease are also connected causally. "Future studies should identify risk factors as well as the biological and psychological mechanisms responsible for these associations, in order to develop interdisciplinary approaches", explains Maion Tegethoff, first-author of the study.
Such treatment should take into account both the physical disease as well as the mental disorder. This would lead to better health care for children and adolescents and would prevent unfavorable long-term effects for individuals as well as for the health care system in general.
As studies get closer to improving patients lives, we need to be very aware of the connection of physical health, diet and depression, easy to talk about, yet harder to grasp in the real, everyday world. Talk to your prescriber if you need more information about your specific needs, it is all about communication that leads to improved outcomes and a better life.
