Studies have revealed that major depressive disorder can be associated with low bone mineral density. Etiology and association are still controversial and matter of huge debate but results have been positive among few studies. According to one study, Bone mineral density in subjects with Major Depressive disorder was 4.7 % lower at the AP spine, 3.5 % lower at the total femur, and 7.3 % lower at the femoral neck as compared to healthy people.
