I strongly agree with this
Depression, Obesity Linked
By Psych Central News Editor
Reviewed by John M. Grohol, Psy.D. on October 9, 2009 A new editorial in the British Medical Journal (BMJ) suggests that primary care doctors should pay more attention to patients who present with obesity, as it has been linked to many common mental disorders, including depression. The researchers add support to claims of a two-way risk between obesity and common mental disorders. The editorial comments on a new research paper on this connection published in the same issue. “A better understanding of the mechanisms for the apparent bi-directional risk between obesity and common mental disorders is needed for effective treatment and prevention," says the lead author of the editorial, Dr. Evan Atlantis from the University of Adelaide’s School of Medicine. “Although the topic is largely unexplored, several psychosocial, lifestyle and physiological factors may be involved in the complex inter-relationship between obesity and mental illness," he says. “Obese people — especially those who perceive themselves as being overweight — often experience weight-related stigma and discrimination, and consequently present with symptoms of low self esteem, low self worth, and guilt. Obesity is associated with socioeconomic disadvantage and low levels of physical activity, both of which are strong predictors of depression. “Obesity may constitute a chronic stressful state, which in turn can cause significant physiological dysfunction. Such dysfunction would then predispose individuals to depressed mood and associated symptoms," he says. Dr. Atlantis says reduced physical activity and overeating — “particularly comfort foods rich in fats and sugars to improve mood" — are common among depressed and anxious patients. “Activation of the endocannabinoid system, whi*****reases appetite and may simultaneously alleviate depression, is likely to reinforce this eating behavior. Socioeconomic disadvantage may further exacerbate the over-consumption of comfort foods because of their low cost," he says. Dr. Atlantis says patients presenting to their doctor with symptoms of common mental disorders should be assessed for obesity and related chronic diseases, and vice versa. “A multidisciplinary approach that focuses on promoting a healthy lifestyle is important. Further research on how best to deliver lifestyle interventions is needed, along with government action on taxes, tariffs, and trade laws to encourage the supply and consumption of healthy food and physical activity choices," he says.
