Brief Summary: The purpose of this study is to examine calcium absorption and bone mineral density in women with depression

Research indicates that pre-menopausal women with depression have significantly lower bone mineral density BMD than pre-menopausal women without depression Although the mechanisms of BMD loss are unclear researchers believe that individuals with depression have impaired calcium absorption However it is unknown whether the abnormal absorption is a result of depression or a side effect of the drugs used to treat it This study will compare calcium absorption in women with depression and in healthy women without depression

Participants in this study will be given two non-radioactive calcium isotopes One can be taken by mouth and the other must be injected Participants will have the level of isotopes in their urine measured to estimate true fractional calcium absorption TFCA Participants may also have a dual X-ray absorptiometry DEXA scan to measure total body adiposity and lean body mass
Detailed Description: Osteoporosis is a condition that is underdiagnosed and undertreated and often goes unnoticed until a fragility fracture occurs after many years of progressive loss of bone quality Risk factors for osteoporosis include glucocorticoid excess and a pro-inflammatory state both of which we and others have observed in a substantial proportion of patients with Major Depressive Disorder

We have found statistically and clinically significant reductions in bone mineral density BMD in a group of 24 depressed but otherwise healthy pre-menopausal women as compared to 24 healthy closely matched controls The difference was significant at several trabecular bone sites eg 136 at the femoral neck 136 at the Wards triangle and 108 at the trochanter Epidemiological studies indicate that losses in trabecular bone mineral density of these magnitudes are associated with an increased lifetime risk for fracture up to 50

Although the mechanisms of the lower bone mineral density in our patients with past or current depression has not yet been elucidated these subjects showed significantly higher 24-hour urinary free cortisol excretion than their matched controls However the extent of the lower bone mineral density in women with past or current depression cannot be accounted for strictly on the basis of hypercortisolism alone but is likely to require other hormonal or biochemical factors as well

Preliminary data in subjects recruited from a large study of mothers with or without mood disorders and their offspring indicate that a disproportionate number of young adult offspring of mothers with Major Depressive Disorder show reduced BMD 23 of whom had not yet manifested clinical signs or symptoms of mood disorder

In the light of the fact that major depression affects between 5 and 9 of the female population the depression-associated lower bone mineral density potentially predisposes millions of women to enhanced susceptibility to osteoporosis We therefore wish to continue our assessment of bone mineral density in subjects with past or current depression to further document the incidence of lower bone mineral density in a larger series We also wish to identify subjects with past or present depression who have reduced bone mineral density to offer them the possibility of participating in other studies designed to clarify pathophysiologic mechanisms involved in low bone mineral density identify any clinical characteristics of depressive illness that may predict increased risk of osteopenia or osteoporosis examine the association of low BMD with other endocrine and metabolic disturbances seen in depressive illness and to identify those who may require therapeutic intervention
