Physical Exercise as an Intervention for Depression: Evidence for Efficacy and Mu-Opioid Receptors as a Mechanism of Action

Physical exercise is often cited as an important part of an intervention for depression, and there is empirical evidence to support this. However, the mechanism of action through which any potential antidepressant effects are produced is not widely understood. Recent evidence points toward the involvement of endogenous opioids, and especially the mu-opioid system, as a partial mediator of these effects. In this chapter, we discuss the current level of empirical support for physical exercise as either an adjunctive or standalone intervention for depression. We then review the extant evidence for involvement of endogenous opioids in the proposed antidepressant effects of exercise, with a focus specifically on evidence for mu-opioid system involvement.

The Moderating Effects of Physical Activity on the Relationships between Child Maltreatment and Health Outcomes among Korean Adolescents: A Secondary Analysis of the 2020 Korean Children and Youth Rights Survey

Adverse childhood events (ACEs) are associated with poor health outcomes and behaviors. Research has shown that physical activity (PA) can have a protective effect on the relationship between ACEs and health outcomes. This study aimed to explore the moderating effects of PA on the relationships between ACEs (physical and emotional abuse) and physical and psychological health (depression and self-esteem) among South Korean middle school students. The data used in this study were from the 2020 Korean Children and Youth Rights Survey (KCYRS), which had 2640 participants. The results indicated that PA could lessen the negative effects of emotional abuse on physical health and self-esteem. However, there was no significant moderating effect of PA in the relationship between physical abuse and health outcomes. The findings suggest that, while PA might be a protective factor for individuals exposed to emotional abuse, the effects of abuse on engaging in PA and the benefits of PA can be complex. Further research is needed to understand how different types of ACEs affect individuals and how PA can mitigate negative impacts. Health professionals, educators, and stakeholders should provide more opportunities for PA to support healthy behaviors and prevent negative health outcomes in adulthood for youth exposed to ACEs.

Problematic internet use and attachment styles among adolescents in Japan

BACKGROUND

Problematic Internet use (PIU) remains a significant social concern in Japan and across the globe. Numerous studies have been conducted to examine the prevalence of PIU, and its association with lifestyle habits and mental health status. To the best of our knowledge, few studies have examined the association between parental attachment and PIU in Japan. Furthermore, preventive measures in Japan have primarily targeted adolescents via education. Therefore, in this study we explored the association between PIU and attachment styles among adolescents to seek a new approach for the development of appropriate, effective measures.

METHODS

A self-administered survey was conducted at one private (in 2018) and two public junior high schools (in 2020) in Kagawa Prefecture, western Japan. We used the Internet Addiction Test (IAT), the Experiences in Close Relationships-Relationship Structures (ECR-RS) questionnaire, and the Birleson Depression Self-Rating Scale for Children (DSRS-C). Multiple regression analysis was performed to examine the association between IAT scores and attachment styles.

RESULTS

Of 1,413 participants (grades 7-9; 700 boys and 713 girls), 39% of the students showed possible PIU and 3% showed PIU. Students with PIU tended to sleep for shorter durations, access the Internet for long hours, and have a poor mental health status (p < 0.01). PIU was significantly associated with insecure attachment (p < 0.0001).

CONCLUSIONS

The findings of our study imply that improving attachment styles and developing secure attachment between the child and parent might help mitigate and/or prevent PIU.

Recommendations for Physical Activity in Asthma: A Work Group Report of the AAAAI Sports, Exercise, and Fitness Committee

Regular physical activity not only improves general health but also can positively impact asthma outcomes, such as control and quality of life. Despite this, many asthma patients do not engage in regular physical activity because they mistakenly believe that they should restrict exercise participation. Health care providers have an opportunity to influence the physical activity levels of their patients during regular office visits. Nonetheless, health care providers often overlook physical activity counseling as an adjunct to pharmacological therapy in asthma patients, and in particular, overlook physical activity counseling. Some providers who acknowledge the benefits of physical activity report being unaware how to approach a conversation with patients about this topic. To address these issues, members of the Sports, Exercise, and Fitness Committee of the American Academy of Allergy, Asthma, and Immunology (AAAAI) performed a focused literature search to identify and evaluate the effects of physical activity in patients with asthma. The purpose of this report is to summarize the evidence for physical activity's impact on asthma patients' disease control, pulmonary function, and overall well-being. Several subpopulations of patients with asthma, including children, adolescents, and older adults, are considered individually. In addition, this report offers practical recommendations for clinicians, including how to identify and overcome barriers to counseling, and methods to incorporate physical activity counseling into asthma treatment practice.

Adolescents' Physical Activity and Depressive Symptoms: A Psychosocial Mechanism

Guided by the Theory of Planned Behavior (TPB; Ajzen, 1991), this study aimed to test a hypothesized path model of TPB variables (i.e., attitude toward behavior, subjective norm, perceived behavioral control, and intention) with physical activity (PA) and depressive symptoms. A total of 792 Chinese adolescents (M_age = 16.9; SD = 0.82; 54.5% females) completed previously validated questionnaires assessing their TPB variables, PA, and depressive symptoms. Correlation analysis revealed TPB variables were positively associated with PA (p < 0.01), and negatively correlated to depressive symptoms (p < 0.01). The path analyses indicated that the hypothesized model produces a goodness of fit (χ²/df = 16.14/5, CFI = 0.99, RMSEA = 0.06). The findings support the theoretical tenets of TPB and provide empirical evidence of the psychosocial mechanism of PA and depressive symptoms in Chinese adolescents. It suggests that building PA intervention strategies while considering the TPB framework may promote adolescents' physical and mental health.

Clinical Utility and Validity of Exercise Vital Sign in Children

ABSTRACT

We reviewed charts of 14,446 sports medicine patients, children aged 5 to 18 years, over a 3-year period to determine the discriminant validity of Exercise Vital Sign (EVS) questions. A logistic regression analyzed factors related to any moderate to vigorous physical activity (MVPA). A linear regression analyzed factors related to amount of MVPA for those who participated in any weekly MVPA. Overall, 48% of children reported meeting physical activity guidelines for 420 min·wk-1. Overall, children reported 400.36 ± 280.04 min·wk-1 of MVPA. Those with depression had significantly less MVPA than those without (95% confidence interval [CI], -96.65 to -26.31). Girls had significantly less MVPA than boys (95% CI, -59.15 to -40.31). Overweight and obese children reported less MVPA compared with normal weight children (95% CIs, -42.65 to -17.29 and -91.61 to -65.50, respectively). EVS demonstrates strong discriminant validity to detect differences between groups as a function of sex, body mass index, and depression.

Review: Exercise for depression in children and adolescents - a systematic review and meta-analysis

BACKGROUND

The objective of this systematic review was to examine the treatment effects of exercise on children and adolescents with depression compared to either other nonexercise treatments or no treatment. A study protocol was registered in PROSPERO (CRD42018101982).

METHOD

Cochrane Central Register of Controlled Trials (CENTRAL), Medline (Ovid), Embase (Ovid), PsycINFO (Ovid), AMED (Ovid), SPORTDiscus, PEDro, CINAHL (EBSCO), ERIC (EBSCO), Web of Science, and databases for grey literature and dissertations were searched from their inception through 30 August 2020 for randomized controlled trials. Varieties of search terms for depression, children and adolescents, exercise, and study design were applied. No limits were placed on publication year, language or publication type. Registers for ongoing trials were also searched. Two authors independently screened references, extracted data and assessed risk of bias in the included trials. The effect sizes for depression postintervention were pooled in a meta-analysis, and the certainty of the evidence was assessed using GRADE (Grading of Recommendations Assessments, Development, and Evaluation).

RESULTS

13,307 references were screened. Four trials were included (n = 159). Participants were between 12 and 18 years old, and predominantly female. A meta-analysis with a random-effects model was performed, and a moderate effect in favour of exercise on postintervention depression severity was identified (SMD = -0.59, 95% CI = -1.08 to -0.10, p = .02). However, the overall certainty of the evidence for this outcome was low. One trial found a nonsignificant decrease in depression severity at six-month follow-up (n = 42, SMD = -0.59, 95% CI = -1.22 to 0.04, p = 0.07), and the overall certainty of the evidence for this outcome was very low. One trial found no statistically significant differences between the exercise and control groups on quality of life. Other outcomes, including adverse events, psychological well-being and social functioning, were not evaluated.

CONCLUSION

Low certainty evidence suggests that exercise interventions may be associated with a decrease in adolescent depression severity. However, our confidence in the effect estimate is limited, and the true effect may be substantially different. Thus, large, high-quality trials including follow-up periods are needed.

Depressive Symptoms and the Link with Academic Performance among Rural Taiwanese Children

Previous studies reflect a high prevalence of depressive symptoms among Taiwanese adolescents (ages 13–18), but there is an absence of literature related to the risk of depression of children in Taiwan (ages 6–12), particularly among potentially vulnerable subgroups. To provide insight into the distribution of depressive symptoms among children in rural Taiwan and measure the correlation between academic performance, we conducted a survey of 1655 randomly selected fourth and fifth-grade students at 92 sample schools in four relatively low-income counties or municipalities. Using the Center for Epidemiological Studies-Depression Scale (CES-D) we assessed the prevalence of depressive symptoms in this sample, in addition to collecting other data, such as performance on a standardized math test as well as information on a number of individual and household characteristics. We demonstrate that the share of children with clinically significant symptoms is high: 38% of the students were at risk of general depression (depression score ≥ 16) and 8% of the students were at risk of major depression (depression score > 28). The results of the multivariate regression and heterogeneous analysis suggest that poor academic performance is closely associated with a high prevalence of depressive symptoms. Among low-performing students, certain groups were disproportionately affected, including girls and students whose parents have migrated away for work. Results also suggest that, overall, students who had a parent who was an immigrant from another country were at greater risk of depression. These findings highlight the need for greater resource allocation toward mental health services for elementary school students in rural Taiwan, particularly for at-risk groups.

Relation of Physical Activity with the Depression: A Short Review

According to the studies, physical exercise can prove to be a viable tool for the treatment of depressed patients. In the present review, various research studies from the year 2017-2019 were analyzed. Various reviews also confirmed that exercise played important role in the treatment of depression. After study, it was confirmed that structured and adherence to the exercise played an important role in the success of exercise protocol towards the treatment of patients. Conventional methods such as pharmacotherapy and psychotherapy were also discussed. It was also studied that sedentary behavior of patients with mental disorder can affect the patient badly. Therefore, all the studies concluded that exercise can be considered as better tool for the treatment of depressed patients if exercise are structured and protocol are regularly performed.
