(CNN) - It appears the extra pounds that come with obesity may actually protect against depression, according to a new study published by the journal of Molecular Psychiatry Monday.

Researchers in Canada found a gene that predisposes a person to obesity can also ward off depression.

The common perception is that obese people are prone to depression, but researchers say this gene is associated with a lower risk.

They say this "protective affect" showed up in four studies of people of various ethnicities around the world.

They also say the takeaway from their findings is that the gene may have a bigger role in its effect on depression and psychiatry than scientists initially thought.
