Obesity and depression 'strongly linked'

Though mental illness and obesity may not appear to be strongly linked, new research has suggested that healthcare professionals should keep a close eye on the two.

A new study conducted at the University of Adelaide in Australia and published in the most recent edition of the British Medical Journal suggests that that depression and obesity may be closely linked.

The specialists were inspired to conduct the research after a recent study by professor Mika Kivimäki from University College London suggested that two conditions may be associated and are now claiming a two-way risk between obesity and common mental disorders.

Lead author of the study Dr Evan Atlantis from the University of Adelaide's School of Medicine told people with affordable health insurance better understanding of the mechanisms for "the apparent bi-directional risk between obesity and common mental disorders" is needed for effective treatment and prevention.

"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 stated.

Dr Atlantis added that the strongest link appears to be between the unhappiness that being overweight can cause.

"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," he said.

The expert told those with health insurance coverage that obesity is also associated with socioeconomic disadvantage and low levels of physical activity, both of which are strong predictors of depression.

He added that comfort eating of foods which are high in fat and sugar are most likely the biggest reasons for the onset of mental problems in the obese.

"A multidisciplinary approach that focuses on promoting a healthy lifestyle is important. Further research on how best to deliver lifestyle interventions is needed," Dr Atlantis suggested.
