Coaching in healthy dietary practices is evaluated as an indicated depression prevention strategy for older adults at risk. Drawing on evidence from a randomized depression prevention trial, the program is described via a case example and assessed for feasibility and potential efficacy within evidence-based interventions. Older adults receiving dietary coaching showed a low incidence of major depressive episodes and meaningful reductions in depressive symptoms during a 6-week intervention with gains sustained over two years, alongside improved well-being.

Treatment in Psychiatry Coaching in Healthy Dietary Practices in At-Risk Older Adults: A Case of Indicated Depression Prevention Sarah T. Stahl, Ph.D. Steven M. Albert, Ph.D. Mary Amanda Dew, Ph.D. Michael H. Lockovich, L.C.S.W. Charles F. Reynolds, III, M.D. Prevention of major depressive disorder is important because current treatments are only partially adequate in reducing symptom burden and promoting health-related quality of life. Lifestyle interventions maybe a desirable prevention strategy for reasons of patient preference, particularly among older patients from minority groups. Using evidence from a randomized depression prevention trial for older adults, the authors found that coaching in healthy dietary practices was potentially effective in protecting at-risk older adults from developing incident episodes of major depression. The authors describe the dietary coaching program (highlighted in a case example) as well as the feasibility and potential efﬁcacy of the program within the context of evidence-based interventions for preventing episodes of major depression and mitigating symptoms of depression. Older adults receiving dietary coaching experienced a low incidence of major depressive episodes and exhibited a40%250% decrease in depressive symptoms, as well as enhanced well-being, during the initial 6-week intervention; these gains were sustained over2years. The authors also describe why lifestyle interventions like coaching in healthy dietary practices may hold promise as effective, practical, nonstigmatizing interventions for preventing episodes of major depressive disorder in older adults with subsyndromal depressive symptoms. (Am J Psychiatry 2014; 171:499–505) Preventing major depressive disorder in older adults could help improve their daily functioning, quality of life, and disease outcomes (1, 2) . As proposed by the Institute of Medicine, an efﬁcient approach is to target mildly symptomatic older adults because they are at highest risk of developing major depression (3–5) . Preventive interventions that focus on at-risk adults with subsyndromal depressive symptoms (“indicated prevention”) would probably have the greatest impact in protecting older adults from the full clinical disorder and preventing the physical and emotional burdens associated with major depression (1, 6, 7). Depression prevention research has shown substantial progress in recent years, building evidence for strategies that effectively reduce or delay the occurrence of incident cases of major depression (8–10). However, there is no gold standard for the prevention of major depression. Clinical researchers continue to ask which intervention to use and how best to implement prevention strategies in communitydwelling elderly populations. The optimal intervention isone that both alleviates depressive symptoms and prevents the downstream burdens of major depression (1) . Given the accelerated pace of the aging of the U.S. population and the projected doubling of older adults living with depression by 2030, identifying and disseminating successful approaches to depression prevention is essential. While conducting a randomized trial testing problem-solving therapy as indicated prevention, we observed a promising strategy for the prevention of major depression. In this trial, our attention control arm—coaching in healthy dietary practices—also appeared to protect older adults from incident episodes of major depression over 2 years of follow-up, reduce symptom burden, and improve health-related quality of life (11) . This evidence is preliminary, given the absence of a concurrent usual-care control condition, but it may help inform the development of lifestyle interventions aimed at preventing major depression in at-risk older adults. Data from a recent meta-analysis indicate an incidence rate reduction of 20%225% for psychological interventions relative to usual care (12). We observed greater reductions in both arms of

FAQs

Why is preventing major depressive disorder important for older adults?

Current treatments are only partially adequate in reducing symptom burden and supporting health-related quality of life. Targeting older adults with mild symptoms can help reduce risk and prevent downstream burdens.

How did coaching in healthy dietary practices affect depressive outcomes?

In the trial, older adults receiving dietary coaching had a low incidence of major depressive episodes and showed decreased depressive symptoms during the initial intervention. Improvements were reported as sustained over two years.

What makes lifestyle interventions promising compared with antidepressant medication?

Older patients may prefer counseling over antidepressant medication for treating depression, and antidepressants show minimal benefit relative to placebo in subsyndromal depression. Dietary coaching is presented as nonpharmacological, practical, and nonstigmatizing.
