Study Shows Older Veterans Less Likely to Receive Treatment for Depression
The 12-month prevalence rate of major depressive disorder (MDD) among individuals living in the U.S. is about 7%, but rates of diagnosed depression are nearly twice as high (12%) among Veterans treated in the VA healthcare system. Given that less education and lower income have been found to be associated with increased rates of depression, older Veterans may be at higher risk for depression than those in the general population. This study examined the likelihood that older Veterans who were newly diagnosed with depression received antidepressants, psychotherapy, or both over a 12-month period. Using VA data, investigators identified 147,631 Veterans, 50 years and older, who received a new diagnosis of depression in FY08 and were treated in the VA healthcare system. They also examined associations between socio-demographics, psychiatric and medical comorbidities, and the receipt of depression treatment.
Findings show that 64% of Veterans with a new diagnosis of depression received some form of treatment within 12 months; however, one third (36%) of the Veterans in this study did not receive any treatment for their depression. Of those Veterans who did receive treatment, most received both antidepressants and psychotherapy (27%), followed by 21% who received antidepressants only, and 16% who received psychotherapy only. The odds of receiving any kind of treatment decreased notably with increasing age. Veterans ages 50 to 64 were more likely to receive antidepressants, psychotherapy, or both compared to those in the older age groups. Results also showed that depressed older adults with no medical comorbidities were more likely to receive both antidepressants and psychotherapy compared to no treatment. This study highlights the importance of continued outreach and intervention efforts for depressed older Veterans who are vulnerable to being under-treated.
