Mental Health and Physical Activity最新文献

Background

24-h movement behavior (24-HMB) guidelines suggest that children and adolescents should limit screen time (ST), get an adequate amount of sleep (SL), and engage in a sufficient amount of physical activity (PA) to ensure optimal health. However, it is not fully understood how adherence to these 24-HMB guidelines apply specifically to visually impaired children and adolescents. To address this gap in the literature, a cross-sectional study was conducted to investigate potential associations between adherence to the 24-HMB guidelines and academic, social, and emotional outcomes among a national sample of visually impaired children and adolescents.

Methods

Data on movement behaviors (physical activity, screen time, and sleep duration) and specific outcome variables (academic performance, social function, and emotional function) were collected through caregiver-proxy reports (questionnaires completed by the caregivers of the visually impaired children and adolescents aged between 6 and 17 years). Logistic regressions were performed to examine the associations between the adherence to 24-HMB guidelines and academic, social, and emotional outcomes adjusting for covariates (e.g., age, sex, race, weight, birth status, household poverty level, and the caregiver's education level) and calculate the odds ratio with 95% confidence interval (CI).

Results

Among 907 visually impaired children and adolescents, only a small proportion adhered to all three 24-HMB guidelines (6.12%). The prevalence of adhering to the SL (33.16%) was higher than those participants meeting PA (3.68%) and ST guidelines (10.28%). As compared to participants who did not meet any of the three 24-HMB guidelines, adhering to: (1) PA + ST guidelines were linked to better academic performance; (2) PA + ST guidelines were linked to less social difficulties, and (3) SL + ST guidelines were linked to better emotional functioning.

Conclusion

Less than one-third of the visually impaired children and adolescents did meet one or more guidelines of the 24-HMB recommendations. Adhering to the 24-HMB guidelines, both alone and in an integrated manner, was linked to better academic performance, social relationships, and emotional functioning while visually impaired children and adolescents who adhered to PA + ST guidelines benefited the most. Our results suggest that the promotion of the 24-HMB guidelines among visually impaired children and adolescents might be an effective intervention strategy to promote academic, social, and emotional development among this unique group, although further research is necessary to empirically buttress this assumption.

Physical activity has a demonstrated positive effect on youth depressive symptoms. However, very few studies have explored the bi-directionality of the links between physical activity and depression. The present study aims at filling this gap and tests whether any associations are moderated by sex. Moreover, the role of subtype of depressive symptoms, vegetative (i.e., lack of energy, poor sleep) or non-vegetative (i.e., mood-related), is explored. Participants were 910 12–13 year-old Swedish adolescents (56% girls) who answered a three-wave survey at ages 12–13 (T1), 15–16 (T2), and 18–19 (T3). Using a cross-lagged structural model, depression predicted decreased frequency of vigorous physical activity (VPA) from T1 to T2 (β = −0.09, p < .05) and from T2 to T3 (β = −0.10, p < .01), while frequency of VPA at T2 decreased depression at T3 (β = −0.12, p < .05). Associations did not differ between boys and girls. Non-vegetative symptoms predicted decreased frequency of VPA from T1 to T2 (β = −0.10, p < .05), while frequency of VPA at T2 predicted decreased non-vegetative symptoms at T3 (β = −0.15, p < .05). Vegetative symptoms predicted decreased frequency of VPA from T1 to T2 (β = −0.09, p < .05), while have a reciprocal influence with VPA from T2 to T3. Overall, our results highlight an association across adolescence between VPA and depression. The association becomes stronger and reciprocal in middle adolescence, which suggests this period as an effective developmental time to plan physical-activity-based interventions to decrease youth depressive symptoms.

Children with neurodevelopmental, emotional, or behavioural challenges participate in lower levels of physical activity (PA) and subsequently have poorer physical and mental health outcomes. We sought to determine the feasibility and preliminary efficacy of a multi-component physical literacy program for children with neurodevelopmental, emotional, or behavioural challenges. Thirty children and 28 parents were recruited to participate in the 10-week single-group non-randomised feasibility trial. Thriving Families was designed to promote children's physical literacy through (a) providing programmed opportunities for PA, (b) incorporating parents, (c) supporting motivation and engagement, and (d) utilising behaviour change techniques. Program feasibility was determined using qualitative and quantitative feedback. Preliminary efficacy was determined through pre-and post-intervention assessments of children's physical literacy. Results indicate that the program is acceptable and was well received. Effect size estimates for parent knowledge (d = 0.78) and confidence (d = 0.57) were moderate to large; however, little change was observed for parents' motivation to support PA and children's perceptions of PA support. Moderate or large effects were observed for pre-to-post-program change on children's domains of physical competence. The Thriving Families program appears to be feasible and acceptable for community-based implementation and may provide benefits for physical and psychological outcomes.

The relation between anxiety sensitivity and physical activity is important because of the significant physical and mental health improvements physical activity yields for individuals with elevated anxiety sensitivity. Most studies suggest anxiety sensitivity has a negative relation with physical activity; however, there are mixed results regarding the presence and magnitude of this association. This study aimed to synthesize and analyze the existing literature to clarify the presence/magnitude of this association and assess various potential moderators. A comprehensive search identified 43 eligible studies, including 10,303 participants. Results revealed a significant, albeit small magnitude, inverse relation between anxiety sensitivity and physical activity without intervention (r = -.09). The relation was stronger with increasing physical activity intensity. Mental health status moderated the relation with general samples (versus clinical mental health samples). The relation was significant for physical and cognitive concerns, but not social concerns. These results suggest elevated anxiety sensitivity is associated with lower levels of physical activity, which is a risk factor for many health concerns and, therefore, anxiety sensitivity should be targeted for interventions to increase physical activity involvement.

Background

The health benefits of physical activity in adults with depression and type 2 diabetes mellitus (T2DM) are well established, however people with depression and T2DM do not generally reach recommended levels of physical activity. Evidence on how to support physical activity in this group is limited; this is particularly the case in low- and middle-income countries. To develop interventions to promote physical activity, it is important first to understand the barriers and facilitators in this population.

Methods

A qualitative study was conducted in Pakistan using semi-structured individual interviews. Adults diagnosed with depression and T2DM, their carers, and healthcare staff were included. Interviews were audio-recorded and transcribed verbatim. Inductive thematic analysis was used to identify themes.

Results

Twenty-three participants (12 male; 11 female) were recruited. Five themes were generated from the data: 1) Cultural and religious norms and practices influence physical activity behaviours 2) Availability of resources and the potential for incorporating physical activity into routine life determine physical activity behaviours 3) Available healthcare resources can be used to promote physical activity 4) Patients’ individual-level characteristics affect their physical activity behaviours 5) Technology-based interventions may be used to promote physical activity.

Conclusion

Individual, cultural, and healthcare system level barriers and facilitators can affect the participation of people with depression and T2DM in physical activity. Religious, social, cultural, domestic, and occupational activities provide opportunities to perform physical activities. Furthermore, harnessing routinely available healthcare resources and the use of technology-based interventions can facilitate the promotion of physical activity.

Background

Patients with chronic heart failure often experience symptoms during physical activity, such as shortness of breath and tachycardia, which may result in fear of physical activity (FoPA). This study tested whether interoception (i.e., the perception of body sensations) and symptom distress (i.e., negative appraisal of symptoms) are associated with FoPA in outpatients with chronic heart failure.

Method

FoPA was assessed with the Fear of Activities in Situations (FActS) in patients with diagnosed heart failure and healthy controls. A heartbeat tracking task and self-reports were used to assess interoceptive accuracy and interoceptive attention in patients and controls. Heart failure-related distress was assessed using ratings of symptom and treatment burden in patients. Multiple regression models were calculated to determine associations with continuous FoPA scores.

Results

Patients with low FoPA perceived their heartbeats more accurately than patients with high FoPA and healthy controls. Interoceptive accuracy and symptom distress explained almost half of the variance in FoPA, after adjustments for sex and disease severity, in patients with heart failure.

Conclusions

In patients inaccurate interoception and symptom distress were associated with high FoPA, independent of heart failure severity. The perception and appraisal of cardiac arousal and symptoms during physical activity deserve further attention to develop interventions to reduce FoPA in patients with heart failure.

Background

It is unclear whether changes in physical activity (PA) or sugar consumption during the COVID-19 pandemic relate to mental health among adolescents. This study identified profiles of change in PA and sugar consumption during the COVID-19 pandemic, and estimated associations between these profiles and anxiety, depression and wellbeing among French adolescents.

Methods

Data were from the cross-sectional school-based EXIST pilot study conducted one year after the end of the first lockdown. Adolescents provided data on lifestyle behavior changes and mental health during the pandemic using self-report questionnaires. We used latent class analysis to identify profiles of change in PA and sugar consumption, and conducted multinomial logistic regression to estimate associations between these profiles, and mental health.

Results

Among 380 adolescents (52.5% male; 13.5 ± 0.6 years), we identified four change profiles: 1) “increased PA and decreased sugar consumption” (21.8%), 2) “PA and sugar consumption stable over time” (36.1%), 3) “decreased PA and increased sugar consumption” (28.4%), and 4) “consistently low PA and stable sugar consumption over time” (13.7%). Compared to adolescents in profile 1, odds of depression were higher among adolescents in profile 3 (OR [95%CI] = 2.42[1.17; 4.99]) and profile 4 (OR = 3.16; [1.39; 7.19]). Associations were similar for wellbeing, but profiles were unrelated to anxiety.

Conclusions

Unfavorable changes in PA and sugar consumption during the COVID-19 pandemic may have contributed to deteriorating adolescents’ mental health. Future studies should assess long-term effects of the pandemic on PA and sugar consumption, and whether any long-term changes are associated with adolescent mental health.

Background

The reduced ability to adaptively respond to stressors (coping) has been proposed as an underlying mechanism across psychopathology. It is associated with a reduced vagally-mediated heart rate variability (vmHRV) at rest and increased perceived stress. The present study investigated the increase in vmHRV and the reduction in perceived stress as potential mediators of the previously demonstrated intervention effect of exercise on global symptom severity across diagnostically heterogeneous mental disorders.

Methods

Sedentary outpatients with depressive disorders, anxiety disorders, insomnia and attention deficit hyperactivity disorder were randomly assigned to a 12-week standardized exercise intervention (n = 38) or passive control condition (n = 36). Baseline and post-treatment assessments included measures of global symptom severity (Symptom Checklist-90), resting vmHRV (root mean square of successive differences between normal heartbeats), and perceived stress (Perceived Stress Scale). Intention-to-treat analyses were conducted using linear mixed models and structural equations modeling.

Results

Among the intervention group, resting vmHRV increased significantly (d = 0.87, p = .003) but perceived stress did not show a significant reduction (d = −0.32, p = .267) compared to the control group. The increase in vmHRV partially mediated the intervention effect on global symptom severity (ß = −0.05, p = .013).

Conclusion

The study results provide evidence that an increase in vmHRV potentially acts as a partial mediator for the beneficial effects of exercise interventions on symptoms across individuals with mental disorders who may have a diminished ability to cope with stressors.

Research has found significant benefits in using exercise as an adjunct treatment for PTSD, depression, and anxiety. Weight lifting as an adjunct treatment for trauma is an emerging research area with very few empirically based studies. This study used a qualitative grounded theory approach to explore how weight lifting contributes to healing for persons with a trauma history. Forty-six persons (26 = women, 8 = men, 6 = nonbinary, 5 = transgender man, 1 = agender), recruited from a national sample of individuals, who identified as having experienced trauma and who engage in weight lifting, were individually interviewed. Data were analyzed using Charmaz's (2006) constructivist grounded theory strategies. Central themes revealed that past and current trauma experiences created relational and bodily disconnection fueled by hyper- or hypo-vigilance, impulsivity, and dysregulation. Weight lifting healed trauma through the felt sense of the mind-body connection, which created a healthier, more empowered, and connected trauma survivor. Study findings offer important insights to inform the development of trauma-informed gym spaces as well as the integration of weight lifting into trauma recovery programs.

Background

There is limited evidence on the associations between type and timing of different sedentary behaviour with affect in adolescents. This study aimed to investigate within-person associations between different types of sedentary behaviour with core affect among a sample of Australian adolescents and explore if the association differs across different times of the day.

Methods

Using ecological momentary assessment, 119 participants (Mage = 14.7 years, 54% male) self-reported engagement in different types of sedentary behaviour, as well as providing information on their affective states multiple times each day, over a four-day period. Data were analysed using multi-level and time-varying effects models.

Results

Playing video games and having a meal on the weekend was favourably associated with valence and tense arousal. Watching TV or a movie on the weekend was associated with lower tense arousal but also lower energetic arousal. Using social media and reading or doing homework on the weekend were also negatively associated with energetic arousal. Reading or doing homework and using social media on a weekday afternoon were inversely associated with valence. Playing video games using social media and reading or doing homework were inversely associated with energetic arousal on weekdays. Results from the time-varying effects models demonstrated that the magnitude of these effects may differ depending upon the time of the day that the sedentary behaviour occurs.

Conclusions

The type, and to a lesser extent, the timing of sedentary behaviours are differently associated with affect in adolescents. These results may provide unique insights into why some types of sedentary behaviours are related to worse mental health and wellbeing and others are not.
