A recent psychiatric study from the University of Southampton observed a higher incidence of depression among women whose birth weight was less than 6.6 pounds than in women whose birth weight was over 6.6 pounds. Based of a p-value of 0.0248 the researchers concluded there was evidence that low birth weights may be a risk factor of susceptibility to depression.
