You may have heard that depression is linked to insomnia, weight gain, even heart disease. But new research suggests the condition is also bad for your bones. In their review of 23 studies, researchers from the Hebrew University of Jerusalem compared the bone density of 2,327 people suffering from depression to that of 21,141 healthy people and found that those who were depressed had much lower bone density than nondepressed people. Low bone density puts you at risk for osteoporosis. The association between depression and weak bones was stronger in women than men, and premenopausal women were at especially high risk, say the researchers, whose work was published in the journal Biological Psychiatry. Both conditions are treatable, so if you’re suffering from depression, ask your healthcare provider about your risk factors for osteoporosis and do what you can to ward off the disease.
