Physical activity in the prevention and treatment of anxiety and depression

How to improve reward sensitivity - Predictors of long-term effects of a randomized controlled online intervention trial

BACKGROUND

Reward sensitivity is a central maintaining factor of depression. Current treatments fail at sufficiently and reliably modifying reward processing. Therefore, we employed interventions targeting reward sensitivity and evaluated the long-term efficacy of different online interventions, additionally exploring predictors of changes in reward sensitivity.

METHODS

This four-arm randomized controlled trial (RCT) tested the long-term stability of treatment effects during a four-month follow-up in 127 participants of a two-week online intervention (behavioral activation vs. mindfulness and gratitude vs. combination of both). In addition, we investigated predictors of treatment success defined as improvement in reward sensitivity. Predictors we investigated were depressive expectations, stress and the type of reward implemented in the exercises of the intervention (physical activities and social encounters).

RESULTS

The improvement concerning reward sensitivity, as well as the reduction of anhedonia and depressive symptoms was stable over a four-month follow-up. We did not find evidence for differences between the active intervention groups. Positive changes in depressive expectations were a significant predictor of long-term improvements in reward sensitivity.

LIMITATIONS

Only self-report measures were used and the interpretation of the long-term efficacy of the online interventions is limited since the waitlist control condition was not extended to the follow-up.

CONCLUSIONS

Clinicians should focus on violating depressive expectations to facilitate updating the prediction and anticipation of future rewarding experiences. This could be a vital mechanism of change in reward sensitivity. However, future research still needs to unravel what kind of interventions are most effective in targeting reward insensitivity.

Translation, Cross-Cultural Adaptation, and Validation of the Croatian Version of the Athlete Psychological Strain Questionnaire (APSQ)

The aim of this study is to translate, cross-culturally adapt, and validate the Croatian Athlete Psychological Strain Questionnaire (APSQ-Cro) as part of the Sport Mental Health Assessment Tool 1 (SMHAT-1) validation. We assessed the reliability and applicability of the APSQ-Cro among Croatian athletes. The international sports community is increasingly focused on mental health issues in athletes, highlighting the need for early detection tools like the Athlete Psychological Strain Questionnaire (APSQ) and SMHAT-1. We included 869 Croatian competing athletes across 54 sports who received a link to access the WEB-based questionnaire. The Croatian Olympic Board helped in distributing the questionnaires, aiming to reach as many and as diverse a group of registered competing athletes in Croatia as possible. Results showed a Cronbach's alpha of 0.75 for the entire questionnaire, indicating acceptable reliability. An exploratory strategy of factor analysis was used to determine the underlying structure of the APSQ-Cro. For this purpose, the Kaiser-Meyer-Olkin (KMO) test and Bartlett's test for sphericity were performed to ensure the suitability of the data. The KMO test ensured sampling adequacy, with a measure of 0.77 indicating suitability for factor analysis, while Bartlett's test confirmed significant correlations among variables (χ2 = 2779.155, df = 45, p < 0.001), validating the dataset's appropriateness for data reduction techniques. The factor analysis, together with the Cattell scree test and varimax rotation, resulted in a two-factor structure for the APSQ-Cro. Factor 1 included items related to internal psychological struggles, while Factor 2 included items related to external pressures from the athletic environment. These two factors explained 53% of the variability, with Cronbach's alphas of 0.75 and 0.88 for the respective factors. The APSQ-Cro is a valid and reliable tool for assessing distress in Croatian athletes. Croatian athletes' sporting experience will be improved with the broad adoption of the APSQ-Cro, which can help detect early signs of psychological distress and subsequently improve mental health outcomes.

Perceived benefits and barriers to exercise and associated factors among Zimbabwean undergraduate students: a cross-sectional study

Background

Despite the well-documented benefits of regular physical activity (PA), many university students are physically inactive. Personal, socio-economic, and environmental factors predict PA engagement behaviours in university students. There is a need to understand context-specific perceived barriers and benefits to exercise engagement and physical activity levels amongst university students from low-income settings. This study primarily evaluated the barriers and facilitators to PA engagement in Zimbabwean undergraduate students. We also assessed the correlates of perceived barriers and benefits to PA engagement, risk of common mental disorders (CMDs) and health-related quality of life (HRQoL).

Methods

We used a cross-sectional study to recruit 465 university undergraduate students. The Exercise Benefits and Barriers Scale, International Physical Activity Questionnaire (IPAQ), Shona Symptoms Questionnaire (SSQ-8) and EuroQol 5 Dimension (EQ5D-5l) were used to measure barriers and facilitators, physical activity level, risk of depression and anxiety and HRQoL, respectively. Data were analysed through descriptive statistics and logistic regression.

Results and conclusion

Most participants were male (58.5%) with a mean age of 21.7 (SD 1.6) years. Majority of the participants were first year students (37.2%), consumed alcohol (66.5%), did not smoke (88.2%) and had a normal BMI (64.7%). The prevalence of low PA levels was 17.4%, with 33.5% of students at risk of CMDs. The most perceived benefits were in the physical performance (e.g., exercise improves my level of physical fitness) and life enhancement (e.g., exercise improves my self-concept) domains, while the most perceived barriers were lack of exercise infrastructure (e.g., exercise facilities do not have convenient schedules) and physical exertion (e.g., exercise tires me). Food insecurity (AOR 2.51: 95% CI 1.62-3.88) and the risk of CMDs (AOR 0.49: 95% CI 0.32-0.76) were associated with increased odds of experiencing barriers to exercise. Not using substances (AOR = 2.14: 95% CI 1.11-4.14) and a higher self-rated HRQoL (AOR 24.34: 95% CI 1.77-335.13) were associated with increased odds of a high perception of exercise benefits. Improving access to community and on-campus exercise facilities and campus-wide health promotional interventions is necessary to enhance PA amongst university students.

School pressure and psychosomatic complaints among Swedish adolescents: does physical activity play a buffering role?

Background

School pressure is a significant stressor in the lives of adolescents, recognised to be associated with psychosomatic complaints. Therefore, the exploration of potential buffering factors is a relevant task. This study aimed to examine the association between school pressure and psychosomatic complaints and the potentially moderating role of physical activity in a Swedish national sample of adolescents.

Methods

Data were derived from the 2017/2018 Swedish Health Behaviour in School-aged Children (HBSC) survey, involving 3,745 participants aged 11-15 years. School pressure and physical activity were measured using single items. Psychosomatic complaints were assessed through an additive index based on the frequency of eight complaints. Covariates included gender, grade, and family affluence.

Results

Linear regression analyses demonstrated a positive graded association between school pressure and psychosomatic complaints, while an inversely graded association was observed between physical activity and psychosomatic complaints. Physical activity did, however, not moderate the link between school pressure and psychosomatic complaints.

Conclusion

Even though physical activity did not serve as a buffer, the direct effects of school pressure and physical activity on psychosomatic complaints suggest that supporting young people in managing school demands and promoting their engagement in physical activities could be effective measures in alleviating psychosomatic complaints.

Pathologist workload, burnout, and wellness: connecting the dots

No standard tool to measure pathologist workload currently exists. An accurate measure of workload is needed for determining the number of pathologists to be hired, distributing the workload fairly among pathologists, and assessing the overall cost of pathology consults. Initially, simple tools such as counting cases or slides were used to give an estimate of the workload. More recently, multiple workload models, including relative value units (RVUs), the Royal College of Pathologists (RCP) point system, Level 4 Equivalent (L4E), Work2Quality (W2Q), and the University of Washington, Seattle (UW) slide count method, have been developed. There is no "ideal" model that is universally accepted. The main differences among the models come from the weights assigned to different specimen types, differential calculations for organs, and the capture of additional tasks needed for safe and timely patient care. Academic centers tend to see more complex cases that require extensive sampling and additional testing, while community-based and private laboratories deal more with biopsies. Additionally, some systems do not account for teaching, participation in multidisciplinary rounds, quality assurance activities, and medical oversight. A successful workload model needs to be continually updated to reflect the current state of practice.Awareness about physician burnout has gained attention in recent years and has been added to the World Health Organization's International Classification of Diseases (World Health Organization, WHO) as an occupational phenomenon. However, the extent to which this affects pathologists is not well understood. According to the WHO, burnout syndrome is diagnosed by the presence of three components: emotional exhaustion, depersonalization from one's work (cynicism related to one's job), and a low sense of personal achievement or accomplishment. Three drivers of burnout are the demand for productivity, lack of recognition, and electronic health records. Prominent consequences of physician burnout are economic and personal costs to the public and to the providers.Wellness is physical and mental well-being that allows individuals to manage stress effectively and to thrive in both their professional and personal lives. To achieve wellness, it is necessary to understand the root causes of burnout, including over-work and working under stressful conditions. Wellness is more than the absence of stress or burnout, and the responsibility of wellness should be shared by pathologists themselves, their healthcare organization, and governing bodies. Each pathologist needs to take their own path to achieve wellness.

Social isolation, social media use, and poor mental health among older adults, California Health Interview Survey 2019-2020

BACKGROUND

Older adults' engagement on social media may be a resource to reduce loneliness and improve mental health.

PURPOSE

This study aimed to examine loneliness and social media use and its association with severe psychological distress among older adults and whether social media use moderated the association of loneliness on severe psychological distress among older adults.

METHODS

This study is a secondary analysis of the 2019-2020 California Health Interview Survey. The Kessler 6-item Psychological Distress Scale (K6) assessed symptoms of psychological distress, with a K6 score ≥ 13 associated with severe mental illness. Loneliness was measured using a revised Three Item Loneliness Scale (TILS) score. Multiple regression analyses were conducted to examine associations between loneliness and severe psychological distress.

RESULTS

Loneliness, health status, and identification as Asian, remained strong predictors of severe psychological distress among older adults when adjusting for other factors. In bivariate analysis, high-frequent social media users, but did not remain significant when accounting for covariates. Social media use did not moderate the association between loneliness and severe psychological distress.

CONCLUSION

This study underscores the significant impact of loneliness on poor mental health among older adults, emphasizing that while frequent social media use correlates with severe psychological distress, it may not alleviate the association of loneliness on poor mental health, thus highlighting the urgent need to address social isolation and promote genuine social connectedness, particularly among Asian older adults.

Comparative Analysis of High-Frequency and Low-Frequency Transcutaneous Electrical Stimulation of the Right Median Nerve in the Regression of Clinical and Neurophysiological Manifestations of Generalized Anxiety Disorder

Background/Objectives: The anxiolytic effect of transcutaneous electrical nerve stimulation (TENS) is associated with the activation of endogenous inhibitory mechanisms in the central nervous system. Both low-frequency, high-amplitude TENS (LF-TENS) and high-frequency, low-amplitude TENS (HF-TENS) are capable of activating opioid, GABA, serotonin, muscarinic, and cannabinoid receptors. However, there has been no comparative analysis of the effectiveness of HF-TENS and LF-TENS in the treatment of GAD. The purpose of our research was to study the effectiveness of direct HF-TENS and LF-TENS of the right median nerve in the treatment of patients with GAD compared with sham TENS. Methods: The effectiveness of direct HF-TENS and LF-TENS of the right median nerve in the treatment of GAD was studied using Generalized Anxiety Disorder 7-item scale (GAD-7) and the Hamilton Anxiety Rating Scale (HAM-A). 40 patients underwent sham TENS, 40 patients passed HF-TENS (50 Hz-50 μs-sensory response) and 41 patients completed LF -TENS (1 Hz-200 μs-motor response) for 30 days daily. After completion of treatment, half of the patients received weekly maintenance therapy for 6 months. Electroencephalography was performed before and after treatment. Results: Our study showed that a significant reduction in the clinical symptoms of GAD as assessed by GAD-7 and HAM-A was observed after HF-TENS and LF-TENS by an average of 42.4%, and after sham stimulation only by 13.5% for at least 2 months after the end of treatment. However, LF-TENS turned out to be superior in effectiveness to HF-TENS by 51% and only on electroencephalography leads to an increase in PSD for the alpha rhythm in the occipital regions by 24% and a decrease in PSD for the beta I rhythm in the temporal and frontal regions by 28%. The prolonged effect of HF-TENS and LF-TENS was maintained without negative dynamics when TENS treatment was continued weekly throughout the entire six-month observation period. Conclusions: A prolonged anxiolytic effect of direct TENS of the right median nerve has been proven with greater regression of clinical and neurophysiological manifestations of GAD after LF-TENS compared to HF-TENS. Minimal side effects, low cost, safety, and simplicity of TENS procedures are appropriate as a home treatment modality.

Virtual Exercise in Medicine: A Proof of Concept in a Healthy Population

BACKGROUND

Science is beginning to establish the benefits of the use of virtual reality (VR) in health care. This therapeutic approach may be an appropriate complementary treatment for some mental illnesses. It could prevent high levels of morbidity and improve the physical health of patients. For many years, the literature has shown the health benefits of physical exercise. Physical exercise in a VR environment may improve the management of mild to moderate mental health conditions. In this context, we developed a virtual environment combined with an ergocycle (the augmented physical training for isolated and confined environments [APTICE] system).

OBJECTIVE

This study aims to investigate the impact of physical exercise in a VR environment.

METHODS

A total of 14 healthy participants (11 men and 3 women; mean age 43.28, SD 10.60 years) undertook 15 minutes of immersive physical exercise using the system. Measures included mindfulness and immersion disposition, subjective perceptions of sensory information, user experience, and VR experience (ie, psychological state, flow, and presence).

RESULTS

First, the APTICE system appears to be a useful tool because the user experience is positive (subscales in the AttrakDiff questionnaire: pragmatic quality=0.99; hedonic quality-stimulation=1.90; hedonic quality-identification=0.67; attractiveness=1.58). Second, the system can induce a positive psychological state (negative emotion, P=.06) and an experience of flow and presence (P values ranging from <.001 to .04). Third, individual immersive and mindful disposition plays a role in the VR experience (P values ranging from <.02 to .04). Finally, our findings suggest that there is a link between the subjective perception of sensory information and the VR experience (P values ranging from <.02 to .04).

CONCLUSIONS

These results indicate that the device is well accepted with positive psychological and exteroceptive outcomes. Overall, the APTICE system could be a proof of concept to explore the benefits of virtual physical exercise in clinical medicine.

Differences in risk of generalized anxiety disorder according to physical activity type in Korea adolescents: The Korea youth risk behavior web-based survey, 2020-2021

Objective

This study aimed to analyze the association between the types of physical activity (PA) and the level of generalized anxiety disorder (GAD) in Korean adolescents.

Methods

This study analyzed data from the Korea Youth Risk Behavior Web-based Survey (KYRBS) for, 2020-2021. The dependent variable was the level of generalized anxiety disorder-7 (GAD-7). The GAD-7 scores were divided into four levels: normal, mild, moderate, and severe. The independent variables were moderate PA, vigorous PA, and strength exercises. Sex, school grade, body mass index, stress, depression, suicidal thoughts, violent victimization, drinking, smoking, substance abuse, sleep satisfaction, and sedentary time were selected as confounding variables.

Results

The independent variable and all confounding variables showed significant differences with the level of GAD-7 (all p < .001). After adjusting for all confounding variables, we observed a 1.062 elevation in mild anxiety disorders, a 1.147 increase in moderate anxiety disorders, and a 1.218 increased incidence of severe anxiety disorders in the absence of vigorous PA. In the absence of strength exercises, there was a 1.057 elevation in mild anxiety disorders, a 1.110 increase in moderate anxiety disorders, and a 1.351 increased incidence of severe anxiety disorders. However, in the case of moderate PA, after adjusting for confounding variables, there was no significant association with GAD-7 levels.

Conclusion

To prevent anxiety disorders among Korean adolescents, the type of PA should be considered. Vigorous PA or strength exercises may help prevent GAD in Korean adolescents.

Voluntary wheel running from early adolescence reduces disease progression, and anxiety- and depression-related symptoms in an adult male mouse model of rheumatoid arthritis

Rheumatoid arthritis (RA) is a multifactorial autoimmune disease that progressively destroys synovial joints and leads to chronic systemic inflammation. This autoimmune disorder is associated with increased anxiety- and depression-related symptoms, which reduces quality of life. Clinical and experimental evidence suggests that higher physical activity from early adolescence may prevent chronic diseases and reduce the risk of mental health problems in adulthood. This study aimed to assess whether voluntary wheel running from early adolescence can decrease clinical symptoms, anxiety- and depression-related behaviors in adult mice with rheumatoid arthritis. Adolescent male mice were exposed to voluntary wheel running until adulthood and got collagen-induced arthritis. We measured body weight, the thickness of the hind paw and knee joint (clinical signs), anxiety- and depression-related behaviors, serum testosterone, and cytokines (IFN-γ IL-1β, IL-6, TNF-α, IL-10). The findings showed that collagen-induced arthritis resulted in anxious-like behavior, increased anhedonia, elevated IL-6, IL-1β, TNF-α, and IFN-γ, and decreased testosterone levels in the serum of mice. However, no change was observed in behavioral despair. We found that higher physical activity from early adolescence significantly reduced the severity of clinical signs, anxiety- and anhedonia-like behaviors, and decreased behavioral despair in RA-induced mice. In addition, the running wheel exposure normalized RA-induced abnormalities in testosterone and inflammatory cytokines in mice. Altogether, this study suggests that higher physical activity from early adolescence may make mice less vulnerable or resistant to RA-induced clinical symptoms and anxiety- and depression-related behaviors by changing testosterone and inflammatory cytokines productions in adulthood.

The Role of Daily Steps in the Treatment of Major Depressive Disorder: Secondary Analysis of a Randomized Controlled Trial of a 6-Month Internet-Based, Mindfulness-Based Cognitive Behavioral Therapy Intervention for Youth

BACKGROUND

Current evidence supports physical activity (PA) as an adjunctive treatment for major depressive disorder (MDD). Few studies, however, have examined the relationship between objectively measured PA and MDD treatment outcomes using prospective data.

OBJECTIVE

This study is a secondary analysis of data from a 24-week internet-based, mindfulness-based cognitive behavioral therapy program for MDD. The purpose of this analysis was twofold: (1) to examine average daily step counts in relation to MDD symptom improvement, and whether pain moderated this relationship; and (2) to examine whether changes in step activity (ie, step trajectories) during treatment were associated with baseline symptoms and symptom improvement.

METHODS

Patients from the Centre for Addiction and Mental Health were part of a randomized controlled trial evaluating the effects of internet-based, mindfulness-based cognitive behavioral therapy for young adults (aged 18-30 years old) with MDD. Data from 20 participants who had completed the intervention were analyzed. PA, in the form of objectively measured steps, was measured using the Fitbit-HR Charge 2 (Fitbit Inc), and self-reported depression severity was measured with the Beck Depression Inventory-II (BDI-II). Linear regression analysis was used to test PA's relationship with depression improvement and the moderating effect of pain severity and pain interference. Growth curve and multivariable regression models were used to test longitudinal associations.

RESULTS

Participants walked an average of 8269 steps per day, and each additional +1000-step difference between participants was significantly associated with a 2.66-point greater improvement (reduction) in BDI-II, controlling for anxiety, pain interference, and adherence to Fitbit monitoring (P=.02). Pain severity appeared to moderate (reduce) the positive effect of average daily steps on BDI-II improvement (P=.03). Higher baseline depression and anxiety symptoms predicted less positive step trajectories throughout treatment (Ps≤.001), and more positive step trajectories early in the trial predicted greater MDD improvement at the end of the trial (Ps<.04). However, step trajectories across the full duration of the trial did not significantly predict MDD improvement (Ps=.40).

CONCLUSIONS

This study used objective measurements to demonstrate positive associations between PA and depression improvement in the context of cognitive behavioral treatment. Pain appeared to moderate this relationship, and baseline symptoms of anxiety and depression predicted PA trajectories. The findings inform future interventions for major depression. Future research with larger samples should consider additional moderators of PA-related treatment success and the extent to which outcomes are related to PA change in multimodal interventions.

This review aims to provide an updated examination of the relationship between anxiety, depression, and heart disease. The review begins by exploring the prevalence of anxiety and depression in heart patients, highlighting the substantial rates at which these mental health disorders co-occur in this population. It further elucidates the risk factors that contribute to the development and exacerbation of anxiety and depression in individuals with heart conditions, including biological, psychological, and social factors. The impact of anxiety and depression on cardiac outcomes is a central focus of this review. It explores the intricate bi-directional relationship between mental health and cardiovascular health, discussing the mechanisms through which anxiety and depression can lead to adverse cardiac events and worsen existing heart conditions. Additionally, it examines the potential impact of anxiety and depression on treatment adherence, lifestyle modifications, and overall quality of life in heart patients. The review also investigates the diagnostic and assessment methods for anxiety and depression in heart patients, emphasizing the importance of implementing comprehensive screening protocols in clinical settings. In conclusion, this updated review provides valuable insights into the prevalence, impact, assessment, and management of anxiety and depression in heart patients. It underscores the importance of recognizing and addressing these mental health disorders within the context of cardiac care, ultimately aiming to enhance the overall well-being and prognosis of individuals living with heart conditions.

The Role of Physical Activity on the Relationships Between Pain, Anxiety, and Sleep Quality in Older Age

BACKGROUND

Sleep quality is associated with a range of negative outcomes in older adults, including a higher risk for cognitive decline, greater disability, and poorer quality of life. Pain and anxiety are both important factors associated with poor sleep quality. Physical activity (PA) is frequently recommended to enhance sleep quality and may have additional benefits for pain and anxiety symptoms. However, current models have not examined the interplay among these factors in relation to sleep quality in older adults.

METHODS

We examined survey data from a community sample of 281 older adults (aged 55-98 years). Bootstrapped mediation and moderated mediation models using the PROCESS macro in SPSS were used to analyze indirect pathways from pain and anxiety to sleep quality and the conditional effects of exercise.

RESULTS

Higher levels of pain and anxiety were significantly and independently associated with poorer sleep quality in older adults. The effect of pain on sleep quality was partially mediated by anxiety symptoms. PA significantly moderated the effects of anxiety on sleep quality, while it did not significantly impact the relationship between pain and sleep quality. The overall indirect effect was not moderated by PA.

CONCLUSION

Pain and anxiety are both significant predictors of sleep quality in older adults, and pain influences sleep quality in older adults partially through its influence on anxiety symptoms. PA may be beneficial for sleep quality for individuals with high anxiety, but patients may see fewer benefits from PA if sleep problems are primarily related to pain.

Transcriptional Profile of Exercise-Induced Protection Against Relapse to Cocaine Seeking in a Rat Model

Background

Exercise has shown promise as a treatment for cocaine use disorder; however, the mechanism underlying its efficacy has remained elusive.

Methods

We used a rat model of relapse (cue-induced reinstatement) and exercise (wheel running, 2 hours/day) coupled with RNA sequencing to establish transcriptional profiles associated with the protective effects of exercise (during early withdrawal [days 1-7] or throughout withdrawal [days 1-14]) versus noneffective exercise (during late withdrawal [days 8-14]) against cocaine-seeking and sedentary conditions.

Results

As expected, cue-induced cocaine seeking was highest in the sedentary and late-withdrawal exercise groups; both groups also showed upregulation of a Grin1-associated transcript and enrichment of Drd1-Nmdar1 complex and glutamate receptor complex terms. Surprisingly, these glutamate markers were also enriched in the early- and throughout-withdrawal exercise groups, despite lower levels of cocaine seeking. However, a closer examination of the Grin1-associated transcript revealed a robust loss of transcripts spanning exons 9 and 10 in the sedentary condition relative to saline controls that was normalized by early- and throughout-withdrawal exercise, but not late-withdrawal exercise, indicating that these exercise conditions may normalize RNA mis-splicing induced by cocaine seeking. Our findings also revealed novel mechanisms by which exercise initiated during early withdrawal may modulate glutamatergic signaling in dorsomedial prefrontal cortex (e.g., via transcripts associated with non-NMDA glutamate receptors or those affecting signaling downstream of NMDA receptors), along with mechanisms outside of glutamatergic signaling such as circadian rhythm regulation and neuronal survival.

Conclusions

These findings provide a rich resource for future studies aimed at manipulating these molecular networks to better understand how exercise decreases cocaine seeking.

Insight and Recommendations for Fragile X-Premutation-Associated Conditions from the Fifth International Conference on FMR1 Premutation

The premutation of the fragile X messenger ribonucleoprotein 1 (FMR1) gene is characterized by an expansion of the CGG trinucleotide repeats (55 to 200 CGGs) in the 5' untranslated region and increased levels of FMR1 mRNA. Molecular mechanisms leading to fragile X-premutation-associated conditions (FXPAC) include cotranscriptional R-loop formations, FMR1 mRNA toxicity through both RNA gelation into nuclear foci and sequestration of various CGG-repeat-binding proteins, and the repeat-associated non-AUG (RAN)-initiated translation of potentially toxic proteins. Such molecular mechanisms contribute to subsequent consequences, including mitochondrial dysfunction and neuronal death. Clinically, premutation carriers may exhibit a wide range of symptoms and phenotypes. Any of the problems associated with the premutation can appropriately be called FXPAC. Fragile X-associated tremor/ataxia syndrome (FXTAS), fragile X-associated primary ovarian insufficiency (FXPOI), and fragile X-associated neuropsychiatric disorders (FXAND) can fall under FXPAC. Understanding the molecular and clinical aspects of the premutation of the FMR1 gene is crucial for the accurate diagnosis, genetic counseling, and appropriate management of affected individuals and families. This paper summarizes all the known problems associated with the premutation and documents the presentations and discussions that occurred at the International Premutation Conference, which took place in New Zealand in 2023.

Age-varying association between depression symptoms and executive function among older adults: Moderation by physical activity

OBJECTIVES

This study assessed trends in depression symptoms, executive function, and their association across age among older adults. Subgroup comparisons were made between older adults meeting and not meeting physical activity guidelines on variables and associations of interest.

METHODS

Participants (n = 2473) were older adults ages 60 to 79 from the 2011-2014 National Health and Nutrition Examination Survey. Depression symptoms, executive function, and physical activity were assessed, and weighted time-varying effect modeling was used for analyses.

RESULTS

Depression symptoms were most severe at age 62 followed by a modest decline before a second peak around age 67. Executive function was highest at age 60 and declined steadily through age 77. Depression symptoms and executive function were negatively associated, but the strength and significance of this association varied with age. Older adults meeting physical activity guidelines had increased executive function and less severe depression symptoms, and meeting physical activity guidelines buffered the association between depression symptoms and executive function at key ages during older adulthood.

CONCLUSIONS

Differences by age should be considered when designing and implementing health programs and treatments focusing on mental health and cognition in older adulthood. Encouraging moderate-intensity physical activity may help protect older adults from depression-related cognitive decline.

The Impact of Social Media on the Mental Health of Adolescents and Young Adults: A Systematic Review

Adolescents increasingly find it difficult to picture their lives without social media. Practitioners need to be able to assess risk, and social media may be a new component to consider. Although there is limited empirical evidence to support the claim, the perception of the link between social media and mental health is heavily influenced by teenage and professional perspectives. Privacy concerns, cyberbullying, and bad effects on schooling and mental health are all risks associated with this population's usage of social media. However, ethical social media use can expand opportunities for connection and conversation, as well as boost self-esteem, promote health, and gain access to critical medical information. Despite mounting evidence of social media's negative effects on adolescent mental health, there is still a scarcity of empirical research on how teens comprehend social media, particularly as a body of wisdom, or how they might employ wider modern media discourses to express themselves. Youth use cell phones and other forms of media in large numbers, resulting in chronic sleep loss, which has a negative influence on cognitive ability, school performance, and socio-emotional functioning. According to data from several cross-sectional, longitudinal, and empirical research, smartphone and social media use among teenagers relates to an increase in mental distress, self-harming behaviors, and suicidality. Clinicians can work with young people and their families to reduce the hazards of social media and smartphone usage by using open, nonjudgmental, and developmentally appropriate tactics, including education and practical problem-solving.

(Trans)forming fitness: Intersectionality as a framework for resistance and collective action

Fitness is a lifelong pursuit, yet many LGBTQ2S+ individuals are averse to group fitness or experiences in big box gyms. Due to the COVID-19 pandemic, virtual fitness programs offered the potential to facilitate opportunities for the greater inclusion of such individuals and the chance to connect, collaborate and advocate for a change in who and what defines fitness. Justice Roe, owner of Fit4AllBodies, utilizes the term fitness industrial complex to provide a framework to discuss the problems of exclusion. His explanation supports research documenting that bodies that are not "the norm", defined by ableism, classism, (hetero)patriarchy and racism, fueled by white supremacy, are oftentimes viewed as "less than" in the fitness and recreation world ( 1- 3). Applying an intersectional framework, this article explores the possibilities for transformative collective action in fitness communities that removes barriers and challenges the injustices that contribute to racialized LGBTQ2S+ individuals feeling unwelcome. With the need to shift to virtual training spaces as a result of a global pandemic, and the rise in the public discourse surrounding racial injustices both on and offline, a sense of belonging and community is important, especially among groups that often face exclusionary practices, such as racialized LGBTQ2S+ community members. These individuals are at greater risk of losing opportunities to access fitness programs that can provide immense health and psychological benefits. What could an intersectional perspective on resistance in sport look like? Using the example of LGBTQ2S+ access to online fitness spaces during the prolonged global COVID-19 pandemic starting in 2020, we suggest that explicit coaching education and intentional communities, centered around social justice, are needed to address the historical roots of systemic oppression, accessibility, and social constructs tied to fitness.

Comparing the efficacy of different types of exercise for the treatment and prevention of depression in youths: a systematic review and network meta-analysis

Purpose

Depression disorder is the most commonly diagnosed type of mental illness among youths. Although a plethora of evidence suggests a positive relationship between exercise and lower levels of depression in youths, the findings regarding the variation in magnitude of this relationship are inconclusive with respect to the preventive and therapeutic effects of different types of exercise. This network meta-analysis aimed to determine the best type of exercise for the treatment and prevention of depression in youths.

Methods

A comprehensive search of databases, including PubMed, EMBASE, The Cochrane Library, Web of Science, PsychINFO, ProQuest, Wanfang, and CNKI, was conducted to identify relevant research on exercise interventions for depression in youth populations. The risk of bias in the included studies was evaluated using Cochrane Review Manager 5.4 according to the Cochrane Handbook 5.1.0 Methodological Quality Evaluation Criteria. The network meta-analysis was performed using STATA 15.1 to calculate the standardized mean difference (SMD) of all concerned outcomes. The node-splitting method was used to test the local inconsistency of the network meta-analysis. Funnel plots were used to evaluate the potential impact of bias in this study.

Result

Utilizing data extracted from 58 studies (10 countries, 4,887 participants), we found that for depressed youths, exercise is significantly better than usual care in reducing anxiety (SMD = -0.98, 95% CI [-1.50, -0.45]). For non-depressed youths, exercise is significantly better than usual care in reducing anxiety (SMD = -0.47, 95% CI [ -0.66, -0.29]). In the treatment of depression, resistance exercise (SMD = -1.30, 95% CI [ -1.96, -0.64]), aerobic exercise (SMD = -0.83, 95% CI [-1.10 -0.72]), mixed exercise (SMD = -0.67, 95% CI [-0.99, -0.35]), and mind-body exercise (SMD = -0.61, 95% CI [-0.84, -0.38]) all showed significant efficacy over usual care. For the prevention of depression, resistance exercise (SMD = -1.18, 95% CI [-1.65, -0.71]), aerobic exercise (SMD = -0.72, 95% CI [-0.98, -0.47]), mind-body exercise (SMD = -0.59, 95% CI [-0.93, -0.26]), and mixed exercise (SMD = -1.06, 95% CI [-1.37 to -0.75]) were all significantly effective compared to usual care. According to the test of the surface under the cumulative ranking score (SUCRA), the ranking of exercises for the treatment of depression in depressed youths is as follows: resistance exercise (94.9%) > aerobic exercise (75.1%) > mixed exercise (43.8%) > mind-body exercise (36.2%) > usual care (0%). For the prevention of depression in non-depressed youths, resistance exercise (90.3%) > mixed exercise (81.6%) > aerobic exercise (45.5%) > mind-body exercise (32.6%) > usual care (0%). Resistance exercise thus had the best comprehensive effect on both the treatment and prevention of depression in youths (clusterank value = 1914.04). Subgroup analyses show that a frequency of 3-4 times per week, a duration of 30-60 min, and a length of more than 6 weeks were found to be the most effective interventions for depression (P > 0.001).

Conclusion

This study provides compelling evidence that exercise is a viable intervention for improving depression and anxiety in young individuals. In addition, the study emphasizes the importance of selecting the appropriate type of exercise to optimize treatment and prevention. Specifically, the results suggest that resistance exercise, performed 3-4 times per week, with sessions lasting 30-60 min and a length of more than 6 weeks, yields optimal results for the treatment and prevention of depression in young individuals. These findings have significant implications for clinical practice, particularly given the challenges associated with implementing effective interventions and the economic burden of treating and preventing depression in young people. However, it is worth noting that additional head-to-head studies are necessary to confirm these findings and strengthen the evidence base. Nevertheless, this study provides valuable insights into the role of exercise as a potential treatment and preventative measure for depression in young people.

The 50 most-cited review papers on physical activity and depression: A bibliometric analysis

A growing body of literature has demonstrated the preventive role of physical activity in depression, and relevant research is rapidly on the rise. The aim of this study was to conduct a bibliometric analysis of the 50 most-cited review papers on physical activity and depression, thus identifying important research topics and future research directions.

METHODS

The 50 most-cited review articles were identified and extracted from the Web of Science Core Collection database (on 31^st October 2022), and a bibliometric citation analysis was performed using the Microsoft Excel and VOSviewer software (Version 1.6.18). Information on the country, authors of publications, publishing journals, citations (i.e., total or annual), keywords, and other meaningful data was analysed comprehensively.

RESULTS

The 50 most-cited review articles received, on average, 247.5 citations per article. Most review articles were from England, with contributions from some highly cited researchers and research teams. Western countries/regions, such as England, Australia, and the USA were the most influential in publishing review articles on physical activity and depression. The Journal of Affective Disorders and Cochrane Database of Systematic Reviews were the journals that published the most highly cited review articles on physical activity and depression. Important research topics on the literature on physical activity and depression focused on (1) different types of physical activity and depression; (2) intervention studies related to physical activity and depression; (3) fitness and physical activity levels in people with depression; (4) methodological analyses in physical activity and depression studies; and (5) the impact of physical activity on depression in different populations.

CONCLUSION

This study reveals that review studies on physical activity and depression have great potential to develop further knowledge. This study also highlights some future research directions, which can serve to effectively advance the knowledge base.

Association Between 24-Hour Movement Guideline and Physical, Verbal, and Relational Forms of Bullying Among Chinese Adolescents

The Canadian 24-Hour Movement Guidelines for Children and Youth recommends specific guidance in physical activity, screen time, and sleep duration. The current research will further explore potential exposures between healthy movement and being involved in a bullying incident as a bully or a victim in a representative sample of adolescents in China. A total of 67 821 Chinese students (response rate = 98.4%) were included in this study (mean age = 13.04 years). The results showed that meeting sleep recommendation only, meeting screen time recommendation only, and meeting both these two recommendations might be protective factors against being bullied or bullying others. Meeting moderate-to-vigorous physical activity (MVPA) recommendation only reported higher odds of being victims in all forms of bullying while meeting both MVPA and another combination of the guideline would relate to lower odds of being a bully and a bully-victim in all forms of bullying involvement.

Motivation, Physical Activity, and Affect in Community-Dwelling Stroke Survivors: An Ambulatory Assessment Approach

BACKGROUND

Motivation is a frequently reported but far less studied driver for post-stroke physical activity participation. Motivation and physical activity may be important contributors to the prevention management and alleviation of affective symptoms among stroke survivors.

PURPOSE

To investigate the real-time associations between motivation, physical activity, and affect in the daily lives of community-dwelling stroke survivors using ecological momentary assessment (EMA) and accelerometry.

METHODS

Forty community-dwelling stroke survivors wore an accelerometer on the thigh and completed EMA surveys assessing motivation (autonomous motivation, controlled motivation) and affect (negative affect, positive affect) eight times daily for 7 days. Multivariate regression analysis and multilevel modeling investigated the associations between motivation, physical activity, and affect.

RESULTS

Greater autonomous motivation for physical activity was associated with less sedentary behavior (β = -0.40, p = .049) and more moderate-to-vigorous physical activity (β = 0.45, p = .020) participation in daily life. Greater autonomous motivation was momentarily associated with less depressed affect (β = -0.05, p < .001) and greater positive affect (β = 0.13, p < .001). Moreover, greater controlled motivation was momentarily associated with greater depressed affect (β = 0.06, p < .001). More intense physical activity was momentarily associated with greater positive affect (β = 0.13, p = .016). No moderating effect of motivation on the association between physical activity and affect was found.

CONCLUSIONS

Motivation and physical activity are momentarily associated with affect among stroke survivors. Assessing and fostering autonomous motivation may be beneficial for promoting physical activity and managing positive and depressed affect as stroke survivors return to the community.

The strategies of exercise intervention for adolescent depression: A meta-analysis of randomized controlled trials

Purpose

This study aimed to investigate the effect of exercise intervention, and analyze exercise intervention strategies for adolescent depression through a meta-analysis of RCTs.

Methods

Accordance to PRISMA guidelines, PubMed, Medline, EBSCO, Web of Science, SPORTDiscus, PsycINFO, ProQuest, and CNKI were searched for eligible records. Peer-reviewed studies were included if they met the following criteria: population (mean age of 10-18 years), intervention (physical activity, sport, or exercise), and outcomes (depression, adherence, ITT, dropout, adverse events, follow-up report). The protocol of this systematic review was registered in PROSPERO (CRD42022321683). Effect sizes calculations and methodological quality of exercise intervention (TESTEX scale) were carried out. The certainty of evidence was assessed by GRADE framework.

Results

Thirteen randomized controlled trials were eligible for this review, which comprised a total of 433 adolescents. Compared with the control treatment, the effect of exercise on adolescent depression was moderate (SMD = -0.65, 95%CI: -1.03 to -0.27, p < 0.01). Heterogeneity was substantial (T 2 = 0.30, I 2 = 67%, p < 0.01). The moderating effect analysis showed that exercise intervention characteristics (organization form, exercise frequency, exercise intensity, exercise type, and single exercise session duration) of included studies varied greatly revealing multiple factors that may impact the antidepressant effect of exercise on adolescent depression (I 2 > 50%, p < 0.05). Three studies show that the positive effect of exercise on reducing depression in adolescents remained 40 weeks after the intervention. Moreover, owing to the included studies contained methodological limitations, the certainty of evidence was reduced to moderate level.

Conclusion

This study shows that exercise intervention has a moderate and sustained positive effect on adolescent depression. Our results recommended that adolescents with depression undertake moderate to high intensity group mixed exercise for more than 12 weeks, 20 to 60 min/time, more than 3 times/week. Additionally, our study also shows that the antidepressant effects remained for a long time after the end of exercise interventions. However, following the GRADE framework, we rated the certainty of evidence the primary meta-analysis as moderate evidence due to some limitations of included studies. Therefore, rigorous studies are still needed to verify the results.

Addition of high-intensity interval training to a moderate intensity continuous training cardiovascular rehabilitation program after ischemic cerebrovascular disease: A randomized controlled trial

Introduction

Moderate intensity continuous training (MICT) is usually recommended for stroke or transient ischemic attack (TIA) patients. High intensity interval training (HIIT) has emerged as a potentially effective method for increasing cardiorespiratory fitness (CRF) among clinical populations. Its effectiveness remains to be demonstrated after stroke. A combined program of HIIT and MICT was designed to create a realistic exercise program implemented for a clinical setting to help patients become more active.

Purpose

This study aimed to compare the effects of a 6-month exercise program with either MICT only or a combination of HIIT and MICT and a control group in terms of CRF, cardiovascular risk factors, functionality, cognitive function (Montreal Cognitive Assessment) and depression markers (Hospital Anxiety and Depression Scale).

Methods

This randomized controlled trial started with 52 participants (33 men and 19 women, mean age: 69.2 ± 10.7) divided into three groups: HIIT + MICT combined, MICT, and control. Both exercise groups consisted of 4 weekly sessions including supervised and at-home exercise. Outcomes were assessed at T0 (baseline measure), T6 (end of exercise protocols), and T12 (follow-up), 40 participants having completed the 12-month follow-up.

Results

At T6, both HIIT+MICT and MICT programs provided a similar increase of CRF (3 ml·min-1·kg-1) from baseline (p < 0.01), while the control group showed a global slight decrease. Despite some decrease of CRF at T12 compared to T6, improvement persisted 6 months post-intervention (HIIT + MICT: p < 0.01 and MICT: p < 0.05). The control group decreased compared with baseline (p < 0.05). The two exercise programs induced a comparable increase in self-reported physical activity and a decrease in anxiety and depression markers. Participants in HIIT + MICT and MICT programs declared a good degree of acceptability assessed by the Acceptability and Preferences Questionnaire.

Conclusion

A 6-month HIIT + MICT combined program and a standard MICT program induced similar improvements in CRF, self-reported physical activity and anxiety and depression markers among patients with prior ischemic stroke or TIA compared with a control group. These effects appear to persist over time. Addition of HIIT was safe and considered acceptable by participants. Our results do not support any superiority of the combination HIIT + MICT nor disadvantage vs. MICT in this population.

Acute Wheel-Running Increases Markers of Stress and Aversion-Related Signaling in the Basolateral Amygdala of Male Rats

Physical activity (PA) is a non-invasive, cost-effective means of reducing chronic disease. Most US citizens fail to meet PA guidelines, and individuals experiencing chronic stress are less likely to be physically active. To better understand the barriers to maintaining active lifestyles, we sought to determine the extent to which short- versus long-term PA increases stress- and aversion-related markers in wild-type (WT) and low voluntary running (LVR) rats, a unique genetic model of low physical activity motivation. Here, we tested the effects of 1 and 4 weeks of voluntary wheel-running on physiological, behavioral, and molecular measures of stress and Hypothalamic Pituitary Adrenal (HPA)-axis responsiveness (corticosterone levels, adrenal wet weights, and fecal boli counts). We further determined measures of aversion-related signaling (kappa opioid receptor, dynorphin, and corticotropin releasing hormone mRNA expression) in the basolateral amygdala (BLA), a brain region well characterized for its role in anxiety and aversion. Compared to sedentary values, 1, but not 4 weeks of voluntary wheel-running increased adrenal wet weights and plasma corticosterone levels, suggesting that HPA responsiveness normalizes following long-term PA. BLA mRNA expression of prodynorphin (Pdyn) was significantly elevated in WT and LVR rats following 1 week of wheel-running compared to sedentary levels, suggesting that aversion-related signaling is elevated following short- but not long-term wheel-running. In all, it appears that the stress effects of acute PA may increase molecular markers associated with aversion in the BLA, and that LVR rats may be more sensitive to these effects, providing a potential neural mechanism for their low PA motivation.

Effectiveness of Educational Intervention Based on Transtheoretical Model on Physical Activity and Menopausal Symptoms

Introduction

Menopause is an inevitable part of women's lives. Physical activity as nonhormonal therapy can decrease the symptoms of menopause. This study is aimed at investigating the effect of educational intervention based on the transtheoretical model (TTM) on physical activity and menopausal symptoms of female clients of the health center in Pasargad City, Iran.

Methods

This quasi-experimental study was performed on 140 females admitted to health center of Pasargad City, Fars Province, Iran (intervention = 70 and control = 70). The data collection tool consisted of demographic data, menopause rating scale, international physical activities questionnaire, and TTM questionnaire (stages of change, processes of change, decision-making balance, and self-efficacy) that were completed before and two months after intervention. For intervention group, the educational program was implemented during 5 sessions of 50-55 min. Data were analyzed by SPSS 25 and by using Chi-square test, independent t-test, and paired t-test.

Results

After intervention, the mean scores of physical symptoms are sleep problems, muscle problems and discomfort, psychological symptoms, depression, irritability, and anxiety of intervention group decreased significantly post intervention (p < 0.001). Analysis showed that psychological symptoms, mental fatigue, somatic, and urogenital symptoms, and vaginal dryness increased 2 months after the intervention. Also, the mean score of cons, pros, decision balance, self-efficacy, consciousness raising, dramatic relief, environmental reevaluation, and self-reevaluation have significant changed in intervention group (p < 0.05). In addition, the top percent of progress can be seen in contemplation (31. 5%).

Conclusion

This study showed the effectiveness of educational intervention based on TTM to reduce menopausal symptoms and promote physical activity in postmenopausal women.

Key characteristics including sex, sexual orientation and internet use associated with worse mental health among university students in Brazil and implications

BACKGROUND

The symptoms of anxiety and depression disorders are multifactorial and can trigger a series of problems especially among university students. The aim of this study was to assess the prevalence and associated factors with anxiety and depression symptoms among first-semester university students at a Federal University in Brazil given the paucity of such data and the first semester is the most stressfultime.

METHODS

Cross-sectional study with first-semester university students. The questionnaire included socio-demographic variables, lifestyles, health conditions and the Depression Anxiety Stress Scales. Descriptive analysis was performed, followed by bivariate analysis and Poisson regression analysis.

RESULTS

Three hundred and fifty-six students (65.2%) across a range of courses in their first semester participated. The prevalence of anxiety was 42.5% and depression 33.2%. Regarding symptoms of anxiety and depression disorders, a positive association was observed among females, non-heterosexual, non-white skin color, excessive internet use, lack of physical activity, not attending university parties, having psychological counseling, history of anxiety in first- or second-degree relatives, poor self-rated health and use of psychotropic medicines.

CONCLUSIONS

Due to the high prevalence of anxiety and depression symptoms, the importance of developing programs to promote mental and physical health of university students is highlighted.

The prevalence and factors associated with anxiety symptoms among resident physicians in Oman: a cross-sectional study

Background

Anxiety disorders are a significant factor associated with physician burnout and poor patient care, reported to have a significant frequency among the youth in the Middle East. However, to date, no study has explored the prevalence of anxiety among resident physicians in the Arabian Gulf country of Oman. This cross-sectional study, conducted among a random sample of residents affiliated with the Oman Medical Specialty Board, aimed to examine the frequency and factors associated with anxiety symptoms among them. Participants were asked to complete the General Anxiety Disorder Assessment (GAD-7) to assess anxiety, as well as a socio-demographic questionnaire.

Results

In a total of 251 residents, the prevalence of anxiety was 14.7% (GAD-7 cut-off score ≥ 10). More than 60% of the respondents were female (68.9%). The age breakdown ranged from 25 to 30 years old (66.5%) and the majority were married (64.9%). More than 70% of respondents attended at least 5 shifts in their weekly schedule and received at least 5 on-call shifts from the hospital per week. Logistic regression showed that residents with chronic disease were 2.5 times (95% CI 1.36–4.72, p = 0.003) more likely to have anxiety than those without them. Those residents who did not exercise were 2.1 times (95% CI 1.04–4.46, p = 0.038) more likely to have anxiety than those who exercise often or regularly. Residents who received 6 or more on-calls from the hospital were 2.6 times (95% CI 1.35–5.25, p = 0.005) more likely to have anxiety than those who received 5 or fewer on-calls in a month.

Conclusions

The factors seemingly responsible for anxiety symptoms in this sample of resident physicians are those that are typically associated with poor work-life balance and unhealthy lifestyles. Pending further scrutiny, these results could be used to lay the groundwork for the identification of those who will require more protracted help during their training in Oman and in other culturally similar Middle Eastern countries.

Exploring public attitudes toward live-streaming fitness in China: A sentiment and content analysis of China's social media Weibo

Objectives

Live-streaming fitness is perceived by the Chinese government as an invaluable means to reduce the prevalence of physical inactivity amid the COVID-19 pandemic. This study aims to investigate the public altitudes of the Chinese people toward live-streaming fitness and provide future health communication strategies on the public promotion of live-streaming fitness accordingly.

Methods

This study collected live-streaming fitness-related microblog posts from July 2021 to June 2022 in Weibo, the Chinese equivalent to Twitter. We used the BiLSTM-CNN model to carry out the sentiment analysis, and the structured topic modeling (STM) method to conduct content analysis.

Results

This study extracted 114,397 live-streaming fitness-related Weibo posts. Over 80% of the Weibo posts were positive during the period of the study, and over 85% were positive in half of the period. This study finds 8 topics through content analysis, which are fitness during quarantine; cost reduction; online community; celebrity effect; Industry; fitness injuries; live commerce and Zero Covid strategy.

Conclusions

It is discovered that the public attitudes toward live-streaming fitness were largely positive. Topics related to celebrity effect (5-11%), fitness injuries (8-16%), live commerce (5-9%) and Zero Covid strategy (16-26%) showed upward trends in negative views of the Chinese people. Specific health communication strategy suggestions are given to target each of the negative topics.

Physical activity and mental health in sports university students during the COVID-19 school confinement in Shanghai

Background

In 2022, Shanghai was seriously affected by the coronavirus disease 2019 (COVID-19) pandemic. The government implemented citywide static management for 2 months, as well as all universities in Shanghai, which changed the normal learning and living style of sports students and led to a decline in physical activity level. As the physical activity has a strong correlation with mental health, this study aimed to investigate the current state of physical activity (PA) and mental health of the students in Shanghai University of Sport. It will try to reveal the correlation between PA and depressive symptoms, anxiety symptoms, fear of COVID-19 and smartphone addiction.

Methods

A cross-sectional survey was conducted on a random sample of 400 students who came from six different majors in May 2022 at the Shanghai University of Sport. Respondents completed the International Physical Activity Questionnaire Short Form (IPAQ-SF), the Chinese version of the 9-item Patient Health Questionnaire (PHQ-9), the Chinese version of the Generalized Anxiety Disorder Scale (GAD-7), the Chinese version of the COVID-19 Fear Scale (FCV- 19S), and the Smartphone Addiction Scale (SAS-SV). Demographics, PA, depressive symptoms, anxiety symptoms, fear of COVID-19, and smartphone addiction were compared. A binary logistic regression model was used for the further analysis.

Results

A total of 376 college students were included in the final analysis. Binary logistics analysis showed that moderate physical activity (MPA) was negatively correlated with depression (OR = 0.95, 95%CI = 0.93-0.98), anxiety (OR = 0.97, 95%CI = 0.95-0.99), fear of COVID 19(OR = 0.99, 95%CI = 0.98-0.99)and smartphone addiction (OR = 0.94, 95%CI = 0.9-0.98) (all P < 0.05). Sedentary behavior was positively correlated with smartphone addiction (OR = 1.01, P < 0.01, 95%CI = 1.001-1.004).

Conclusion

There was an association between the presence of MPA and depressive symptoms, anxiety symptoms, fear of COVID-19, smartphone addiction, and sedentary behavior associated with smartphone addiction levels. Clarifying the causal relationship between PA and mental health will require further research.

Investigation of gender differences in multivariate associations between physical activity and psychological distress

ObjectiveThe study examined gender differences in the relationship between physical activity (PA) and psychological distress in college students. Participants: The participants were recruited at a university in the U.S. (91 subjects) and another university in South Korea (164 subjects) in November 2016. Methods: The subjects participated in an online survey. Results: PA had a significant association with a decrease of Psychological Distress only in women (β = -.27). Moreover, Social Support for PA (β = -.11) and PA Self-Efficacy (β = -.08) had an indirect effect on Psychological Distress only in Women. Conclusions: Only women showed a significant association between PA and psychological distress. PA Self-Efficacy and Social Support for PA were indirectly associated with Psychological Distress only in women. Moreover, women could be motivated to be physically active by both Social Support for PA and PA Self-Efficacy, whereas men could be motivated to exercise by PA Self-Efficacy.

A Minireview Exploring the Interplay of the Muscle-Gut-Brain (MGB) Axis to Improve Knowledge on Mental Disorders: Implications for Clinical Neuroscience Research and Therapeutics

What benefit might emerge from connecting clinical neuroscience with microbiology and exercise science? What about the influence of the muscle-gut-brain (MGB) axis on mental health? The gut microbiota colonizes the intestinal tract and plays a pivotal role in digestion, production of vitamins and immune system development, but it is also able to exert a particular effect on psychological well-being and appears to play a critical role in regulating several muscle metabolic pathways. Endogenous and exogenous factors may cause dysbiosis, with relevant consequences on the composition and function of the gut microbiota that may also modulate muscle responses to exercise. The capacity of specific psychobiotics in ameliorating mental health as complementary strategies has been recently suggested as a novel treatment for some neuropsychiatric diseases. Moreover, physical exercise can modify qualitative and quantitative composition of the gut microbiota and alleviate certain psychopathological symptoms. In this minireview, we documented evidence about the impact of the MGB axis on mental health, which currently appears to be a possible target in the context of a multidimensional intervention mainly including pharmacological and psychotherapeutic treatments, especially for depressive mood.

Do healthy habits regulate the relationship between psychosocial dysfunction by COVID-19 and bidimensional mental health?

COVID-19 has affected mental health and well-being. Lifestyles are relevant to understand the impact of psychosocial dysfunctions. The objective was to examine the role of healthy habits in the relations between psychosocial dysfunction and psychological well-being/distress during COVID-19. Participants completed measures of psychosocial dysfunction, healthy habits, life satisfaction, well-being, depression, and anxiety symptoms. Psychosocial dysfunction was associated with distress symptoms, while health habits were associated with well-being. Healthy habits were mediators: greater psychosocial dysfunction was associated with less healthy habits, which in turn were associated with lower overall well-being, and greater depression. Programs addressing healthy habits can be of great utility.

Adolescent Soccer Athletes’ Irrational Beliefs About Basic Psychological Needs are Related to Their Emotional Intelligence and Mental Health

There has been a scarcity of research regarding the unique mental health risk factors that adolescent athletes face. The recently proposed Rational Emotive Self Determination Scale for Adolescents (RESD-A) has been suggested to understand some of the antecedent and associative factors of adolescent athlete mental health. The principal aim of this study is to examine the structural and criterion validity of the RESD-A in an athlete sample for the first time. To achieve this aim, two hundred and forty-two club level soccer athletes participated in the study. Confirmatory factor analysis (CFA) was conducted to test the validity of the RESD-A’s factor structure. Partial correlation analyses with the subscales of RESD-A, emotional intelligence, and mental health scores were used to examine criterion validity. Initial results for the structural and criterion validity of the RESD-A with an athlete population are promising. The potential importance, limitations and directions for future research are discussed.

Physical activity and healthcare utilization in France: evidence from the European Health Interview Survey (EHIS) 2014

Background

A growing need and focus on preventing and controlling the diseases and promoting a healthier lifestyle is more evident at global, regional, and national levels. In this respect, it is well-known the positive association between physical activity and population’s health, but also its negative association with the demand of healthcare, which could lead to lower spending on healthcare systems. In France, a lack of physical activity, a high prevalence of sedentary behaviours, and a continuous deterioration of these behaviours are observed since 2006. Therefore, promoting and increasing physical activities could contribute to major societal issues. Within this context, the study aims to analyse how the use of different healthcare services are related to physical activity in a nationally representative sample of French population.

Methods

The data used was retrieved from the second wave of the EHIS-ESPS 2014. The relationship between physical activity and healthcare utilization, controlled by a set of socioeconomic, demographic, and health behaviour factors, was explored both at the level of the entire population and separately for two age groups (less than 65 years, 65 years and older), employing probit and recursive multivariate probit models.

Results

Our findings underline that the relation between healthcare utilization and physical activity depends on the type of healthcare services and age group. In this respect, only among adult respondents, we observe a significant negative association between physical activity and prescribed medicines consumption and day hospitalization, while preventive services use is positively related to physical activity. Common to both age groups, the positive association of physical activity with general physician services and non-prescribed medicines reveal that moderately and highly active adults and elders may be more health conscious and therefore may seek referrals to generalist and other prevention measures more frequently than their inactive counterparts. This explanation is also sustained by the negative association between physical activity and overnight hospitalization or home healthcare services.

Conclusions

This study highlights the double role of physical activity on health as preventive measure and treatment and thus support the implementation of public health policies aimed at increasing the level of physical activity in French population.

Antidepressant Effect of Intermittent Long-Term Systemic Administration of Irisin in Mice

Depression is a psychiatric disorder increasingly diffused worldwide. Evidence suggests that irisin, a myokine secreted by contracting muscle, mediates beneficial effects on several targets, including the brain. Here, the potential antidepressant properties of long-term intermittent systemic irisin administration (100 µg/kg/weekly for 1 month) were evaluated in mice by the Tail Suspension Test (TST), Forced Swim Test (FST), and Open Field Test (OFT). Furthermore, to deepen the molecular pathways underlying irisin treatment, the expression of irisin precursor, neurotrophic/growth factors, and cytokines was analyzed. Irisin treatment significantly decreased the immobility time in the TST and FST, suggesting an antidepressant effect. Additionally, irisin seemed to display an anxiolytic-like effect increasing the time spent in the OFT arena center. These findings were probably due to the modulation of endogenous brain factors as the gene expression of some neurotrophins, such as brain-derived neurotrophic factor (BDNF) and insulin-like growth factor (IGF-1), was upregulated only in irisin-treated mouse brain. Moreover, irisin modulated the expression of some cytokines (IL-1β, IL-4, IL-6, and IL-10). To the best of our knowledge, this is the first study demonstrating that the irisin antidepressant effect may be observed even with a systemic administration in mice. This could pave the way toward intriguing preclinical research in humans.

Rapid treatments for depression: Endocannabinoid system as a therapeutic target

Current first-line treatments for major depressive disorder (MDD), i.e., antidepressant drugs and psychotherapy, show delayed onset of therapeutic effect as late as 2-3 weeks or more. In the clinic, the speed of beginning of the actions of antidepressant drugs or other interventions is vital for many reasons. Late-onset means that depression, its related disability, and the potential danger of suicide remain a threat for some patients. There are some rapid-acting antidepressant interventions, such as sleep deprivation, ketamine, acute exercise, which induce a significant response, ranging from a few hours to maximally one week, and most of them share a common characteristic that is the activation of the endocannabinoid (eCB) system. Activation of this system, i.e., augmentation of eCB signaling, appears to have anti-depressant-like actions. This article puts the idea forward that the activation of eCB signaling represents a critical mechanism of rapid-acting therapeutic interventions in MDD, and this system might contribute to the development of novel rapid-acting treatments for MDD.

Modeling the effects of physical activity, education, health, and subjective wealth on happiness based on Indonesian national survey data

BACKGROUND

Studies on physical activity's psychological benefits are generally fewer than those on its physiological benefits, and these limited studies have mostly investigated its impact on cognitive functions. Studies exclusively investigating physical activity's effects on happiness are rare. This study aims to investigate the effect of physical activity on psychological functions, especially on happiness.

METHODS

Analysis was based on a large field of nationally representative Indonesian adult data. Data were compiled based on face-to-face interviews with 12,051 adults. Participants provided measures of physical activity, subjective health, and happiness, and responses were recorded with computer-assisted personal interviewing (CAPI) software. Demographic data, including gender, subjective wealth, education, and age, were also included in the analysis. Structural equation modeling (SEM) was conducted to determine the relationship between physical activity, health, subjective wealth, and happiness.

RESULTS

The tested model of the association between physical activity, health, subjective wealth, and happiness indicated a good fit, based on χ² (1, n = 12,051) = 48.733, p = .001, RMSEA = .063, and CFI = .97. Path analysis results showed that health conditions mediated the effects of physical activity on happiness. The result also showed positive effects of education level and subjective wealth on happiness.

CONCLUSION

This study provides evidence that engagement in physical activity has a positive impact on happiness. Indonesian adults should engage in more active lifestyles since more than one-third of Indonesians did not get enough physical activity.

Higher Consumption of Fruit and Vegetables Is Associated With Lower Worries, Tension and Lack of Joy Across the Lifespan

Background and Aims

Higher total fruit and vegetable (FV) intakes have been associated with lower perceived stress. However, the relationship of FV intake with domains of perceived stress is unclear. The aim of this cross-sectional study was to explore the relationship between consumption of FV and four perceived stress domains (worries, tension, lack of joy and demands) in a population-based cohort of Australian adults.

Methods

Participants (n = 8,640) were men and women aged ≥25 years from the Australian Diabetes, Obesity and Lifestyle (AusDiab) Study. Dietary intake was assessed using a 74-item validated Food Frequency Questionnaire. Perceived stress domains were determined using a validated 20-item version of the Perceived Stress Questionnaire, with higher scores representing higher perceived stress. Cut-offs for high perceived stress domains were obtained from the highest quartiles of each domain for each sex. Multivariable-adjusted logistic regression was performed to investigate cross-sectional associations.

Results

The mean age of participants (50.1% females) was 47.8 (SD 15) years. Those with higher intakes of FV, combined and separately, had a significantly lower odds (16–36%) for higher worries, tension and lack of joy, independent of other lifestyle factors.

Conclusion

In Australian adults, higher consumption of FV was associated with lower odds of worries, tension and lack of joy. Following the dietary guidelines for the recommended intake of FV may help improve feelings of worries, tension and lack of joy, which are linked to mental health problems.

Web-based exercise interventions for patients with depressive and anxiety disorders: a systematic review of randomized controlled trials

OBJECTIVE

The number of people suffering from depression and/or anxiety has increased steadily due to the coronavirus disease 2019 (COVID-19) pandemic. In this context, web-based exercise interventions have emerged as a potential treatment strategy. The objective of this study was to synthetize evidence from randomized controlled trials regarding the effects of web-based exercise interventions on patients with depressive and/or anxiety disorders.

METHODS

Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Six databases were searched (Cochrane Library, EBSCO, PubMed, SciELO, Scopus, and Web of Science), and eligible articles were identified according to a PICOS inclusion-exclusion approach (participants with depressive or anxiety disorders; web-based exercise interventions; active or passive control group; assessment of changes in depressive or anxiety disorders; randomized design). Primary outcomes were depressive and/or anxiety symptoms. The quality of evidence was assessed with Grading of Recommendations Assessment, Development, and Evaluation.

RESULTS

Of 7,846 search results, three studies met the inclusion criteria (172 participants between 18 and 65 years of age, 95.9% women). The web-based exercise interventions lasted 8-12 weeks and involved endurance training, yoga, or combined endurance and strength training. The comparators involved non-exercise controls or active controls. Compliance rates were low. Web-based exercise interventions were not superior to controls regarding anxiety symptoms, and only one study found benefits for depressive symptoms (p ≤ 0.05). The quality of the cumulative evidence was low.

CONCLUSION

The available data regarding the effects of web-based exercise interventions on depression and/or anxiety symptoms is scarce, the risk of bias is high, and the quality of the cumulative results is low. Currently, no clear recommendations can be provided.

Developing Scotland's First Green Health Prescription Pathway: A One-Stop Shop for Nature-Based Intervention Referrals

Introduction

Lifestyle modifications are part of comprehensive treatment plans to help manage the symptoms of pre-existing chronic conditions. However, behavior change is notoriously difficult as patients often lack the necessary support. The present manuscript outlines the development of a Green Health Prescription pathway that was designed to link patients with appropriate lifestyle interventions (i.e., nature-based interventions) and to support attendance. Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis was undertaken in three focus groups (i.e., National Health Service healthcare professionals, service-users, and nature-based intervention delivery partners) to highlight areas of strength and weakness within the proposed pathway prior to delivery. The SWOT analyses revealed that the pathway was supported by all three focus groups. Weaknesses and threats were identified including sustainability of nature-based interventions in terms of funding, the need to connect patients with appropriate interventions based on their physical and mental health needs, and the requirement to have a “one-stop shop” for information to ensure that the pathway was accessible for all service-users and healthcare professionals. Results were addressed and considered throughout the development of the pathway.

Discussion

The Green Health Prescription pathway was launched in 2019 and gave patients the ability to receive a prescription from a healthcare professional, community service, or to self-refer. The pathway allows patients to contact a consultant, via a telephone service, who is trained to match them with a programme that the patient believes will be enjoyable and that fits their treatment needs. Data collection to assess the efficacy of the pathway is ongoing.

Can we reduce psychosomatic symptoms and work presenteeism with physical activity?

BACKGROUND: Past studies have tended to consider the relationships between presenteeism, physical activity and psychosomatic symptoms in a partial manner and not as a whole. OBJECTIVE: This cross-sectional study investigated the relationship between physical activity, psychosomatic symptoms and presenteeism, in order to increase the visibility of presenteeism and promote workplace health. METHODS: Two questionnaires (Patient Health Questionnaire and Work Limitations Questionnaire) with a set of physical activity questions were administered on the sample of 514 employees. RESULTS: The results showed a statistically significant relationship between presenteeism and some variables of physical activity, as well as between presenteeism and psychosomatic symptoms. Further results showed a statistically significant association between psychosomatic symptoms and some variables of physical activity. General evaluation (adequacy) of physical activity, and lack of general, aerobic physical activity proved to be important predictors of presenteeism, while general, aerobic physical activity also predicted psychosomatic symptoms. Analysis of the results revealed that psychosomatic symptoms moderate the relationship between physical activity and presenteeism. CONCLUSIONS: The article points out that employees with health problems have a lower percentage of productive time than healthy employees. However, developing an active lifestyle can be a cost-effective measure to cope with presenteeism and promote psychophysical health among employees.

Preschool Temperament as a Factor of Risk and Protection for Later Childhood Psychopathology

BACKGROUND

Temperament might be considered as a risk factor as well as a resilience factor for later externalizing and internalizing disorders. Therefore, this study examines different dimensions of temperament in preschool age with regard to their predictive value for psychopathology later in childhood.

METHODS

A total of 76 patients (63.2% male) were assessed in a special psychiatric consultation for preschool age at measuring point time t1 (x = 4.2) and measuring point time t2 (x = 9.2). At t1, the Integrative Child Temperament Inventory (ICTI) was used for assessment. At t2, parents completed the Strengths and Difficulties Questionnaire SDQ. Multiple regression analyses were used to test if the temperament factors of the ICTI predicted clinical abnormalities in the SDQ subscales or total difficulties score.

RESULTS

SDQ total difficulties score as an indicator of total psychiatric disturbance in childhood appears to be good predicted by the temperament factor frustration/anger. Sensory sensitivity in preschoolers serves as a risk factor for later emotional symptoms, whereas high activity levels appear to prevent later emotional symptoms. Behavioral inhibition appears to protect against hyperactivity/inattention.

CONCLUSION

Our data suggests that preschool temperament contributes differently to the development of externalizing and internalizing problems in childhood. The temperament factor frustration/anger in preschool children might be a strong predictor of the general mental condition in childhood at nine years of age and can therefore be used as a target for prevention of psychopathology in children. On one hand, high sensory sensitivity can be a predictor to identify preschool children at risk for later emotional symptoms, on the other hand, activity level acts as a protective factor against later emotional symptoms. An increased level of behavioral inhibition might be protective against the development of hyperactivity/inattention symptoms. Overall, this study illustrates the complexity and ambiguity of temperament in child development.

Self in medicine: Determinants of physician well-being and future directions in improving wellness

CONTEXT

Medicine, a profession dedicated to the wellness of patients, is struggling with a crisis of physician and trainee wellness. Physicians and trainees are burning out at alarming rates. Historically, medicine has been characterised by challenging working conditions and inattention to physician wellness and self-care. Healthy physicians are better at promoting wellness to their patients, and physicians who are suffering from burnout can deliver compromised patient care.

DISCUSSION

In recent years, research has increasingly focused on the causes of unwellness among doctors, and a broad range of health determinants have been identified. Studies of interventions for improving trainee and physician wellness have identified individual-focused and organisational approaches that can address the root causes of burnout. Insights from the corporate workplace may help guide interventions. Strategies for addressing physician burnout and improving wellness will involve innovative and multifaceted approaches. Despite a growing emphasis of physician wellness in the literature, implementation of wellness interventions is lagging, and quality improvement methods can address these challenges.

CONCLUSION

Physician wellness is a shared responsibility among doctors, health care organisations and governing bodies. Addressing burnout and improving physician wellness will require transformational change and the embracement of a culture of wellness in medicine. Quality improvement methods are the next step in identifying effective wellness interventions and the targeted groups of physicians and trainees who will most benefit.

Greater baseline connectivity of the salience and negative affect circuits are associated with natural improvements in anxiety over time in untreated participants

BACKGROUND

There is limited research examining the natural trajectories of depression and anxiety, how these trajectories relate to baseline neural circuit function, and how symptom trajectory-circuit relationships are impacted by engagement in lifestyle activities including exercise, hobbies, and social interactions. To address these gaps, we assessed these relations over three months in untreated participants.

METHODS

262 adults (59.5% female, mean age 35) with symptoms of anxiety and depression, untreated with pharmacotherapy or behavioral therapy, completed the DASS-42, WHOQOL, and custom surveys at baseline and follow-up to assess symptoms, psychosocial function, and lifestyle activity engagement. At baseline, participants underwent fMRI under task-free and task-evoked conditions. We quantified six circuits implicated in these symptoms: default mode, salience, negative and positive affect, attention, and cognitive control.

RESULTS

From baseline to 3 months, some participants demonstrated a natural improvement in anxiety (24%) and depression (26%) symptoms. Greater baseline salience circuit connectivity (pFDR=0.045), specifically between the left and right insula (pFDR=0.045), and greater negative affect circuit connectivity elicited by sad faces (pFDR=0.030) were associated with anxiety symptom improvement. While engagement in lifestyle activities were not associated with anxiety improvements, engagement in hobbies moderated the association between negative affect circuit connectivity and anxiety symptom improvement (p = 0.048).

LIMITATIONS

The observational design limits causal inference.

CONCLUSIONS

Our findings highlight the role of the salience and negative affect circuits as potential circuit markers of natural anxiety symptom improvements over time. Future studies that identify biomarkers associated with symptom improvements are critical for the development of personalized treatment targets.
