Leptin levels are associated with decreased depressive symptoms in women across the weight spectrum, independent of body fat
Clinical Endocrinology, 04/02/2012Lawson EA et al.
The negative relationships between leptin and severity of symptoms of both depression and anxiety remained significant after controlling for body fat or weight. There was no relationship between ghrelin and symptoms of depression or anxiety. Although ghrelin levels were positively associated with the degree of perceived stress, this relationship was not significant after controlling for body fat or weight. Leptin may mediate depressive symptoms across the weight spectrum. Further investigation of the role of leptin in modulating mood will be important.
