A Pilot Study of the Views of General Practitioners Regarding Exercise for the Treatment of Depression

Lessons and Untapped Potential of Smartphone-Based Physical Activity Interventions for Mental Health: Narrative Review

BACKGROUND

Physical activity has well-known and broad health benefits, including antidepressive and anxiolytic effects. However, only approximately half of Americans meet even the minimum exercise recommendations. Individuals with anxiety, depression, or related conditions are even less likely to do so. With the advent of mobile sensors and phones, experts have quickly noted the utility of technology for the enhanced measurement of and intervention for physical activity. In addition to being more accessible than in-person approaches, technology-driven interventions may uniquely engage key mechanisms of behavior change such as self-awareness.

OBJECTIVE

This study aims to provide a narrative overview and specific recommendations for future research on smartphone-based physical activity interventions for psychological disorders or concerns.

METHODS

In this paper, we summarized early efforts to adapt and test smartphone-based or smartphone-supported physical activity interventions for mental health. The included articles described or reported smartphone-delivered or smartphone-supported interventions intended to increase physical activity or reduce sedentary behavior and included an emotional disorder, concern, or symptom as an outcome measure. We attempted to extract details regarding the intervention designs, trial designs, study populations, outcome measures, and inclusion of adaptations specifically for mental health. In taking a narrative lens, we drew attention to the type of work that has been done and used these exemplars to discuss key directions to build on.

RESULTS

To date, most studies have examined mental health outcomes as secondary or exploratory variables largely in the context of managing medical concerns (eg, cancer and diabetes). Few trials have recruited psychiatric populations or explicitly aimed to target psychiatric concerns. Consequently, although there are encouraging signals that smartphone-based physical activity interventions could be feasible, acceptable, and efficacious for individuals with mental illnesses, this remains an underexplored area.

CONCLUSIONS

Promising avenues for tailoring validated smartphone-based interventions include adding psychoeducation (eg, the relationship between depression, physical activity, and inactivity), offering psychosocial treatment in parallel (eg, cognitive restructuring), and adding personalized coaching. To conclude, we offer specific recommendations for future research, treatment development, and implementation in this area, which remains open and promising for flexible, highly scalable support.

Knowledge, attitude, and practice of patients with major depressive disorder on exercise therapy

BACKGROUND

This study aimed to explore the knowledge, attitude, and practice (KAP) toward exercise therapy of patients with major depressive disorder (MDD).

METHODS

This cross-sectional study was conducted at the First Hospital of Shanxi Medical University between April and October 2023 in patients with MDD. A self-designed questionnaire was used to evaluate the KAP (Cronbach's α = 0.787). The minimum-maximum scores were 2-23 for knowledge, 11-55 for attitude, and 7-35 for practice.

RESULTS

A total of 494 valid questionnaires were analyzed. The mean KAP dimension scores were 15.39 ± 3.34/23 (66.91%), 36.54 ± 19.33/55 (66.44%), and 19.33 ± 5.22/35 (55.23%), indicating poor knowledge, negative attitude, and weak practice. Multivariable logistic regression analysis showed that female (OR = 0.613, 95%CI: 0.376-1.000, P = 0.050), urban residence (OR = 0.443, 95%CI: 0.259-0.758, P = 0.003), suburban residence (OR = 0.047, 95%CI: 0.016-0.138, P < 0.001), higher income (OR = 3.889-7.928, all P < 0.001), and unclear self-reported depression level (OR = 0.078, 95%CI: 0.027-0.221, P < 0.001) were independently associated with the knowledge scores. Knowledge scores (OR = 1.102, 95%CI: 1.022-1.188, P = 0.011), female gender (OR = 0.437, 95%CI: 0.246-0.776, P = 0.005), city (OR = 0.410, 95%CI: 0.226-0.744, P = 0.003), married (OR = 3.577, 95%CI: 1.751-7.650, P < 0.001), higher income (OR = 0.065-0.392, both P < 0.050), depressive trend (OR = 2.640, 95%CI: 1.110-6.278, P = 0.028), high depression score level (OR = 0.176, 95%CI: 0.104-0.300, P < 0.001), and unclear self-reported depression score (OR = 0.023, 95%CI: 0.007-0.076, P < 0.001) were independently associated with the attitude scores. Finally, knowledge scores (OR = 1.130, 95%CI: 1.051-1.215, P = 0.001), attitude scores (OR = 1.199, 95%CI: 1.124-1.280, P < 0.001), and city (OR = 0.583, 95%CI: 0.352-0.965, P = 0.036) were independently associated with the practice scores. The structural equation modeling analysis showed that knowledge, but not attitude (β = 0.103, P = 0.092) or practice (β = 0.034, P = 0.603), influenced the depression level (β=-0.074, P < 0.001); attitude influenced practice (β = 0.369, P < 0.001).

CONCLUSION

The KAP toward exercise among MDD patients is poor in Shanxi. Females, people living in urban or suburban areas, with lower income, and self-reported unclear depression levels should be targeted by education interventions.

Exercise Prescription Practices to Improve Mental Health

OBJECTIVE

There is growing evidence that higher levels of physical activity are associated with better mental health. Furthermore, interventional studies have shown that exercise may improve symptoms in a number of psychiatric conditions. Despite this evidence, relatively little information is available about how these findings have been translated into clinical practice. The goal of this study was to characterize the exercise prescribing practices of health care providers from different subspecialties and evaluate factors that may influence their prescribing practices.

METHODS

We conducted a cross-sectional survey among faculty and staff from a large academic tertiary care medical center in the southeastern United States. Participants were invited to complete the survey via email or departmental newsletters. Descriptive statistics were used to characterize the sample and ordered logistic regression was used to analyze practices about exercise as a therapy for psychiatric illness.

RESULTS

A total of 185 respondents completed the survey. More than half of the providers (58%) reported that they regularly recommend exercise as part of the treatment for patients with psychiatric conditions; however, few providers offered specific exercise instructions (24%) or followed national guidelines (30%). Depression (84.9%) and anxiety (69.2%) were the most common indications for exercise prescription, while insufficient knowledge or training was the most common barrier to prescribing exercise. We also found significant differences in prescription practices depending on the providers' formal clinical degree and their reported personal exercise habits.

CONCLUSIONS

Exercise is recognized by most clinicians as a therapeutic option for psychiatric conditions. Despite this recognition, only a small proportion provide recommendations consistent with national guidelines or empirical research.

The Role of the Clinical Exercise Physiologist in Reducing the Burden of Chronic Disease in New Zealand

Clinical exercise physiologists (CEPs) specialize in managing long-term, non-communicable health conditions using scientific rehabilitative exercise prescription, which alleviates the burden of these conditions on health care systems. This is evident, particularly in Australia (AUS), where they are registered as health care workers. CEPs have been shown to reduce the physical burden of long-term conditions on populations and the economic load that these place on national health departments. This article aims to evidence the effectiveness of CEPs in Noncommunicable Disease (NCD) rehabilitation, the cost-effectiveness of supervised exercise prescription for various NCDs by CEPs in AUS, and related cost-effectiveness New Zealand (NZ) burden of disease. This article highlights the important role NZ. CEPs can play in reducing chronic disease cost if given the same opportunities as Australian CEPs within NZ's health care system.

Physical Activity Promotes Health and Reduces Cardiovascular Mortality in Depressed Populations: A Literature Overview

Major depression is associated with premature mortality, largely explained by heightened cardiovascular burden. This narrative review summarizes secondary literature (i.e., reviews and meta-analyses) on this topic, considering physical exercise as a potential tool to counteract this alarming phenomenon. Compared to healthy controls, individuals with depression consistently present heightened cardiovascular risk, including "classical" risk factors and dysregulation of pertinent homeostatic systems (immune system, hypothalamic-pituitary-adrenal axis and autonomic nervous system). Ultimately, both genetic background and behavioral abnormalities contribute to explain the link between depression and cardiovascular mortality. Physical inactivity is particularly common in depressed populations and may represent an elective therapeutic target to address premature mortality. Exercise-based interventions, in fact, have proven effective reducing cardiovascular risk and mortality through different mechanisms, although evidence still needs to be replicated in depressed populations. Notably, exercise also directly improves depressive symptoms. Despite its potential, however, exercise remains under-prescribed to depressed individuals. Public health may be the ideal setting to develop and disseminate initiatives that promote the prescription and delivery of exercise-based interventions, with a particular focus on their cost-effectiveness.

Exercise prescription for people with mental illness: an evaluation of mental health professionals' knowledge, beliefs, barriers, and behaviors

OBJECTIVE

The aim of this study was to understand the knowledge, beliefs, barriers, and behaviors of mental health professionals about physical activity and exercise for people with mental illness.

METHODS

The Portuguese version of The Exercise in Mental Illness Questionnaire was used to assess knowledge, beliefs, barriers, and behaviors about exercise prescription for people with mental illness in a sample of 73 mental health professionals (68.5% women, mean age = 37.0 years) from 10 Psychosocial Care Units (Centros de Atenção Psicossocial) in Porto Alegre and Canoas, state of Rio Grande do Sul, Brazil.

RESULTS

Most of respondents had received no formal training in exercise prescription. Exercise ranked fifth as the most important treatment, and most of the sample never or occasionally prescribed exercise. The most frequently reported barriers were lack of training in physical activity and exercise prescription and social stigma related to mental illness. Professionals who themselves met recommended physical activity levels found fewer barriers to prescribing physical activity and did so with greater frequency.

CONCLUSION

Exercise is underrated and underused as a treatment. It is necessary to include physical activity and exercise training in mental health curricula. Physically active professionals are more likely to prescribe exercise and are less likely to encounter barriers to doing so. Interventions to increase physical activity levels among mental health professionals are necessary to decrease barriers to and increase the prescription of physical activity and exercise for mental health patients.

Temporal trends in exercise physiology services in Australia-Implications for rural and remote service provision

OBJECTIVE

To assess temporal trends in service provision by Accredited Exercise Physiologists based on remoteness classification using Australian Bureau of Statistics remoteness classifications of Major Cities, Inner Regional, Outer Regional, Remote and Very Remote.

DESIGN AND PARTICIPANTS

Cross-sectional analysis of publicly available Medicare Benefits Schedule datasets, for Medicare item number 10953 from 2012-2013 to 2016-2017.

MAIN OUTCOME MEASURE(S)

Number of claims, benefits paid, fees charges and number of providers for Medicare item number 10953.

RESULTS

Accredited Exercise Physiologist service delivery demonstrates growth across all areas of remoteness classification. Rebates and fees mirror service delivery trends. The rate of service growth was significantly greater in Major Cities compared with all other remoteness classifications. Provider numbers show a steady increase from 2012-2013 to 2016-2017 but number remains higher in Major Cities compared with all other remoteness locations.

CONCLUSION

Given the high proportion of chronic and complex illness in rural and remote areas, and the limited access to allied health care services, we propose more needs to be done to position Accredited Exercise Physiologists in these regions of increasing need. These findings have implications for future development of the Accredited Exercise Physiologist profession.

Exercise and mental health literacy in an Australian adult population

BACKGROUND

Exercise is a well-established treatment for depression, and its use in clinical care is supported by consumers and clinicians. However, whether public health messages regarding the benefits of exercise for depression have translated to public knowledge remains unknown. This study aims to examine the community's mental health literacy, and views regarding exercise delivery for people with depression.

METHODS

A vignette was presented as part of the telephone-based 2017 National Social Survey (n = 1,265). Interviewees identified what (if anything) was wrong with the person described, who they should seek help from, whether exercise might be beneficial, and how exercise should be delivered for the person described in the vignette. Results are reported using descriptive statistics.

RESULTS

From 1,265 respondents (response rate = 24%, n = 598 males, mean age 54.7 years [range 18-101]), almost two-thirds correctly identified the condition described in the vignette as depression. There was widespread support for seeking help from a general practitioner. Exercise was well supported in the treatment of the person described in the vignette, with general practitioners and accredited exercise physiologists highlighted as persons to consult regarding exercise. Views regarding the type of program were consistent with current best practice recommendations.

CONCLUSIONS

Australian adults demonstrate a high level of exercise and mental health literacy. The high level of support for accredited exercise physiologists is evidence of the effectiveness of health promotion campaigns from peak exercise professional agencies.

Incorporating Exercise Professionals in Mental Health Settings: An Australian Perspective

Low rates of physical activity, in addition to other poor physical health behaviors, contribute to lower quality of life and increased rates of premature mortality for people living with mental illness. Physical activity reduces this mortality gap while simultaneously improving mood, cognitive function, and symptomology for a variety of psychiatric disorders. While physical activity programs are feasible and acceptable in this population, significant barriers exist that limit long-term adherence. Accredited exercise physiologists (AEPs) are best-placed in Australia to lead physical activity interventions for people living with mental illness. Additionally, AEPs provide an important role in improving culture change within mental health settings by influencing clinicians' attitudes to physical activity interventions. Leading international mental health organizations should collaborate and promote the role of physical activity to increase the provision of such services to people living with mental illness.

Self-reported physical activity levels of the 2017 Royal Australian and New Zealand College of Psychiatrists (RANZCP) conference delegates and their exercise referral practices

Background: Physical activity (PA) significantly improves physical health and clinical symptoms across mental disorders. Accredited Exercise Physiologists (AEPs) are trained to lead PA interventions for people with mental illness, but referrals to AEPs are low.Aims: To determine the knowledge and attitudes of delegates attending the 2017 Royal Australian and New Zealand College of Psychiatrists (RANZCP) conference toward physical health monitoring and exercise interventions for people with mental illness.Methods: A cross-sectional survey of RANZCP delegates investigated knowledge and attitudes toward PA for people with mental illness, self-reported PA, and their understanding of AEP's role within mental health settings. A subgroup of delegates underwent fitness assessments.Results: Seventy-three delegates completed surveys and 24 underwent fitness assessments. Delegates demonstrated good knowledge regarding associations between PA and cardiovascular disease risk. Delegates were less knowledgeable of AEP's role within mental health settings. Forty-six participants (63%) did not meet the Australian recommended guidelines for PA. No association between referrals to AEPs and self-reported PA or fitness measures were evident.Conclusions: Promoting PA participation for mental health professionals, coupled with education on the important role AEPs play in the multidisciplinary treatment of mental health consumers is vital to improve health outcomes for this vulnerable group.

Mass media representations of the evidence as a possible deterrent to recommending exercise for the treatment of depression: Lessons five years after the extraordinary case of TREAD-UK

Exercise or physical activity are recommended options within stepped-care treatment models for depression. However, few physicians present these options to patients, in part because of the impression that the supporting evidence is weak or inconsistent. We speculate that the coocurrence of "counter-messaging" and deficient critical appraisal may lead to such impressions. We focus on TREAD-UK (ISRCTN16900744), the largest trial to investigate "whether physical activity can be an effective treatment for depression within primary care". In media statements, researchers declared that exercise was ineffective in lowering depression. We examined (a) the results of the trial, critiques, and rejoinders, (b) the impact on internet searches, and (c) whether TREAD-UK was critically appraised, as reflected in citing articles. We show that the results of TREAD-UK were misrepresented. The media campaign resulted in a fourfold increase in relevant internet searches. Of articles characterising the results, 57% adopted the interpretation that exercise failed to lower depression, whereas only 17% were critiques. We identify similarities to media portrayals of the OPERA (ISRCTN43769277), DEMO (NCT00103415), and DEMO-II trials (NCT00695552). We note a disconcerting trend of media campaigns that misrepresent the effects of exercise on depression and call for increased scrutiny in peer reviewing both pre- and post-publication.

Physical Exercise in Major Depression: Reducing the Mortality Gap While Improving Clinical Outcomes

Major depression shortens life while the effectiveness of frontline treatments remains modest. Exercise has been shown to be effective both in reducing mortality and in treating symptoms of major depression, but it is still underutilized in clinical practice, possibly due to prevalent misperceptions. For instance, a common misperception is that exercise is beneficial for depression mostly because of its positive effects on the body ("from the neck down"), whereas its effectiveness in treating core features of depression ("from the neck up") is underappreciated. Other long-held misperceptions are that patients suffering from depression will not engage in exercise even if physicians prescribe it, and that only vigorous exercise is effective. Lastly, a false assumption is that exercise may be more harmful than beneficial in old age, and therefore should only be recommended to younger patients. This narrative review summarizes relevant literature to address the aforementioned misperceptions and to provide practical recommendations for prescribing exercise to individuals with major depression.

Clinician perspectives and practices regarding the use of exercise in the treatment of adolescent depression

Initial evidence suggests that exercise is an effective method in reducing symptoms of depression amongst adolescents. It is important to examine clinician attitudes and practices regarding the incorporation of exercise in mental health treatment, and to examine potential facilitators and barriers to exercise prescription. An online survey was conducted amongst mental health clinicians (N = 125) working in the treatment of adolescent depression. Clinicians held favourable attitudes towards exercise, most frequently ranking exercise as the second most important treatment for adolescent depression following cognitive behaviour therapy. The majority of clinicians were found to prescribe exercise "always" (24.3%) or "most of the time" (43.4%). Significant positive relationships were found between confidence to prescribe exercise and knowledge surrounding exercise prescription and clinician exercise prescription rates, however no significant relationship was identified between clinician levels of exercise and exercise prescription. The most frequently endorsed barriers to exercise prescription included the belief that exercise prescription should be implemented by an exercise professional, a lack of knowledge surrounding exercise prescription for adolescent depression, and the belief that depressed adolescents will not adhere to an exercise program. Overall, clinicians held positive attitudes towards exercise in the treatment of adolescent depression, and often recommended exercise as part of treatment.

Italian patients with more recent onset of Major Depressive Disorder have a shorter duration of untreated illness

BACKGROUND

Previous investigation on the duration of untreated illness (DUI) in patients with Major Depressive Disorder (MDD) revealed a different latency to first antidepressant treatment, with adverse consequences in terms of outcome for individuals with a longer DUI. Recent reports, moreover, documented a reduced DUI, as observed with the passage of time, in patients with different psychiatric disorders. Hence, the present study was aimed to assess DUI and related variables in a sample of Italian patients with MDD as well as to investigate potential differences in subjects with onset before and after 2000.

METHODS

An overall sample of 188 patients with MDD was assessed through a specific questionnaire investigating DUI and other variables related to the psychopathological onset and latency to first antidepressant treatment, after dividing them in two different subgroups on the basis of their epoch of onset.

RESULTS

The whole sample showed a mean DUI of approximately 4.5 years, with patients with more recent onset showing a significantly shorter latency to treatment compared with the other group (27.1±42.6 vs 75.8±105.2 months, P<.05). Other significant differences emerged between the two subgroups, in terms of rates of onset-related stressful events and benzodiazepine prescription, respectively, higher and lower in patients with more recent onset.

CONCLUSIONS

Our findings indicate a significant DUI reduction in MDD patients whose onset occurred after vs before 2000, along with other relevant differences in terms of onset-related correlates and first pharmacotherapy. Further studies with larger samples are warranted to confirm the present findings in Italy and other countries.

Physical Exercise for Late-Life Depression: Customizing an Intervention for Primary Care

OBJECTIVES

To identify which individual- and context-related factors influence the translation into clinical practice of interventions based on physical exercise (PE) as an adjunct to antidepressants (AD) for the treatment of late-life major depression (LLMD).

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

Primary care with psychiatric consultation-liaison programs (PCLPs)-organizational protocols that regulate the clinical management of individuals with psychiatric disorders.

PARTICIPANTS

Individuals aged 65 and older with major depression according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (N = 121).

INTERVENTION

Participants with LLMD were randomized to AD (sertraline) or AD plus PE (AD + PE).

MEASUREMENTS

Participant characteristics that were associated with greater effectiveness of AD + PE (moderators) were identified, and effect sizes were calculated from success rate differences. Whether the characteristics of the study setting influenced participant flow and attendance at exercise sessions was then explored, and primary care physicians (PCPs) were surveyed regarding their opinions on PE as a treatment for LLMD.

RESULTS

The following participant characteristics were associated with greater likelihood of achieving remission from depression with AD + PE than with AD alone: aged 75 and older (effect size 0.32), polypharmacy (0.35), greater aerobic capacity (0.48), displaying psychomotor slowing (0.49), and less-severe anxiety (0.30). The longer the PCLP had been established at a particular center, the more individuals were recruited at that center. After participating in the study, PCPs expressed positive views on AD + PE as a treatment for LLMD and were more likely to use this as a therapeutic strategy.

CONCLUSIONS

The combination of PE and sertraline could improve the management of LLMD, especially when customized for individuals with specific clinical features. Liaison programs might influence the implementation of similar interventions in primary care, and PCPs viewed them positively.
