• To prevent death and disability from chronic diseases
• To promote maternal, infant, and adolescent health • To promote healthy personal behaviors • To accomplish these goals in partnership with health and education agencies, major voluntary associations, the private sector, and other federal agencies
Chronic diseases are becoming increasingly prevalent causes of morbidity and mortality in the world

And, remember, in the absence of diagnosis and treatment, depressive disorders often assume a persistent course — becoming chronic diseases in their own right…

HOW DO THEY INTERACT?
Yet, a MEDLINE search for literature reviews of *chronic disease/ x *depression/ yielded only two articles…
METHODS
Conducted MEDLINE search of *mental disorders/ or *depression/ x the following diseases or conditions: *asthma/ *arthritis/ *cardiovascular disease/ *cancer/ *diabetes/ *obesity/
Selection Criterion for Chronic Diseases and Conditions • highly prevalent • major sources of morbidity and/or mortality • costly • of programmatic relevance to the work of the Centers for Disease Control and Prevention
Selection Criteria for Studies Reviewed • empirical investigations • provided definitional or diagnostic criteria for depression, depressive symptoms, and relevant chronic disease or condition • specified interval of observation or time course

• “Anxious depressive” symptoms reported among youth with moderate or severe asthma

Treatments for Depression Investigated Among Persons with Asthma
• Cognitive-behavioral therapy • Physical activity
Sources: Grover et al., J Assoc Physicians India, 2002; Hurwitz, Ann Epidemiol, 2003
Cognitive Behavioral Therapy (CBT) Among Persons with Asthma
• Patient monitors automatic thoughts, identifies cognitive traps, and furnishes rational rebuttal • Example: “I forgot my inhaler! I’m so stupid – now I’m bound to have an attack!” CBT Among Persons with Asthma • Cognitive traps: all-or-none thinking, labeling, fortune telling.
• Rational rebuttal: “I forgot my inhaler, so next time I’ll post a note to remind myself inside the front door. And I’ve gone several days without any problems…” • CBT has yielded significant reductions in both depressive and asthma symptoms
ARTHRITIS

Effects of Arthritis SelfManagement Program
• positive effect on perceived self-efficacy • improved communication with physicians • lessened self-reported fatigue and pain • decreased depressive and anxiety symptoms

Rheumatoid Arthritis and Depression
• CBT reduces depressive symptoms, especially when initiated early in the course of RA
• CBT most effective when tailored to particular concerns of patient with RA (pain, disability)
• Antidepressant medication associated with significant improvements in both psychological and health status in persons with RA

Osteoarthritis (OA) and Depression
• Tailored program of aerobic and/or resistance exercise is important in the treatment of OA
• In particular, aerobic exercise can ameliorate depressive symptoms and reduce disability and pain • “What’s the worst thing you can do for arthritis? Nothing.”

Outcomes Associated with Post-CVA Depression
• impaired response to rehabilitation • increased mortality

Clinical Pearl: CVA and Depression
• Antidepressant treatment of post-CVA depression is clearly warranted and has also been associated with recovery of cognitive function and significantly increased survival. The merits of “prophylactic” antidepressant use post-CVA may merit consideration.

Depression in Persons with Cancer
• Approximately 20% of patients with ovarian cancer reported to be depressed • Depression in cancer patients crucial
– Associated with desire for hastened death in terminally ill – Increased depressive symptoms inversely related to length of survival

Cancer Treatment May Foster Symptoms Resembling Depression
• Improved hemoglobin levels among patients with cancer undergoing chemotherapy associated with “lifting” of depressive symptoms • As nausea and fatigue are not uncommon among patients being treated for cancer, reliance on “somatic” symptoms may not accurately gauge depression

Use of Antidepressants in Patients with Cancer is Growing

SUMMARY
• The presence of depressive symptoms may be an important risk factor in the etiology of chronic diseases, as well as adversely affecting their course and treatment • The assessment, management, and appropriate referral of patients with depression and other psychiatric disorders is an important aspect of the provision of primary medical care
A FINAL THOUGHT
…and please always remember (and don’t ever forget!), in the absence of effective diagnosis and treatment, depression can become a chronic disease in its own right!
