A scoping review of methodologies for applying artificial intelligence to physical activity interventions

Purpose This scoping review aimed to offer researchers and practitioners an understanding of artificial intelligence(AI)applications in physical activity(PA)interventions;introduce them to prevalent machine learning(ML),deep learning(DL),and reinforcement learning(RL)algorithms;and encourage the adoption of AI methodologies.Methods A scoping review was performed in PubMed,Web of Science,Cochrane Library,and EBSCO focusing on AI applications for promoting PA or predicting related behavioral or health outcomes.AI methodologies were summarized and categorized to identify synergies,patterns,and trends informing future research.Additionally,a concise primer on predominant AI methodologies within the realm of PA was provided to bolster understanding and broader application.Results The review included 24 studies that met the predetermined eligibility criteria.AI models were found effective in detecting significant patterns of PA behavior and associations between specific factors and intervention outcomes.Most studies comparing AI models to traditional statistical approaches reported higher prediction accuracy for AI models on test data.Comparisons of different AI models yielded mixed results,likely due to model performance being highly dependent on the dataset and task.An increasing trend of adopting state-of-the-art DL and RL models over standard ML was observed,addressing complex human–machine communication,behavior modification,and decision-making tasks.Six key areas for future AI adoption in PA interventions emerged:personalized PA interventions,real-time monitoring and adaptation,integration of multimodal data sources,evaluation of intervention effectiveness,expanding access to PA interventions,and predicting and preventing injuries.Conclusion The scoping review highlights the potential of AI methodologies for advancing PA interventions.As the field progresses,staying informed and exploring emerging AI-driven strategies is essential for achieving significant improvements in PA interventions and fostering overall well-being.

Dietary, physical activity, and weight management interventions among active-duty military personnel: a systematic review

Background: Research has been conducted to assess the effectiveness of weight management, dietary and physical activity interventions in military settings. However, a recent and comprehensive overview is lacking. The aim of this systematic review is to examine the evidence and describe key components of effective interventions in terms of improving body composition, dietary behaviors, and physical activity among active-duty military personnel.Methods: Pub Med, Psyc Info, and CINAHL were searched on the 17 th of November 2017 to identify interventions that promoted diet and/or physical activity among active-duty military personnel. Studies were included if they assessed outcomes related to anthropometric measurements, dietary behaviors, or fitness/physical activity levels. There were no restrictions regarding publication date, follow-up duration, and sex. After screening, a total of 136 studies were eligible. Of these studies, 38 included an educational and/or behavioral change component, and 98 had only physical or fitness training as part of basic military training. Only studies that included an educational and/or behavioral change component were assessed for quality using the Effective Public Health Practice Project tool and included in the qualitative synthesis of the results.Results: Based on consistent evidence from studies that were rated as moderate or strong, there is good evidence that military weight management interventions are effective in improving body composition for durations of up to 12 months. Effective interventions are more likely to be high intensity(have a greater number of sessions), are more often delivered by specialists, and use theoretical base/behavioral change techniques and a standardized guideline. Dietary interventions can potentially reduce total fat and saturated fat intake. Dietary interventions that target the kitchen staff and/or increase the availability of healthy food are more likely to be effective in the short term. The results regarding military physical fitness interventions were inconclusive.Conclusions: Despite limitations such as the diversity and heterogeneity of the included interventions, outcome measurements, and follow-up duration, this systematic review found good evidence that weight management interventions are effective, especially in terms of weight loss. More studies are needed to acquire solid evidence for effectiveness for durations longer than 12 months and to identify key components of the effective dietary and physical activity educational and/or behavioral change interventions, especially in countries outside Europe and the US.

Effect of Individualized Nursing Intervention on Patients with Tuberculosis Latent Infection and Active Tuberculosis

Objective:This paper aims to explore the effect of individualized nursing intervention on patients with active tuberculosis(ATB)and latent tuberculosis infection(LTBI).Methods:The nursing study started in January 2020 and ended in January 2023.A total of 60 patients with ATB and LTBI were included,and they were divided into two groups according to the intervention schemes selected for control testing,each with 30 cases.The intervention program selected for group A was routine care,and for group B was individualized nursing.The proportion of adverse reactions,changes in the level of lung items,self-management outcomes and satisfaction were evaluated and compared.Results:After evaluating the proportion of adverse reactions,the total proportion of ATB and LTBI in group B was lower than that in group A(P<0.05).Based on the evaluation and testing of the expiratory flow(EF),expiratory volume(EV),and vital capacity(VC)after the intervention,these levels in group B showed higher outcomes than those in group A(P<0.05).The scores in terms of living habits,sleep,diet,and compliance in group B were higher than those in group A(P<0.05).The total proportion of the satisfaction of ATB and LTBI patients in group B was higher than that in group A(P<0.05).Conclusion:After the intervention of individualized nursing measures in patients with ATB and LTBI,it was found that it can not only play a positive role in the prevention and control of adverse reactions,but also improve their lung function,and promote their self-management,with good satisfaction level,thus it has high research and clinical application values.

The effect of the CHAMP intervention on fundamental motor skills and outdoor physical activity in preschoolers

Purpose: Physical activity(PA) and fundamental motor skills are important components of current and future trajectories of health in young children. This study examined the effects of a 5-week motor skill intervention on preschoolers' motor skill competence and their PA behaviors while participating in the motor skill intervention or outdoor free play(recess).Methods: A total of 102 preschoolers served as participants and were part of a motor skill intervention group(n = 64) or a control/outdoor free play group(n = 38). Children's motor skills were assessed before and after the intervention using the Test of Gross Motor Development-3 rd edition. PA during the motor skill intervention and outdoor free play was assessed using accelerometers both immediately before the start(baseline, Week 0 or Week 1) and end(late, Week 5 or Week 6) of the intervention.Results: All children significantly improved their motor skills from baseline to late assessment(p < 0.05). Children in the motor skill intervention demonstrated greater rates of change(p < 0.001) and scored higher on all motor skills at the late assessment compared with the control group(p < 0.001). There was no effect of group(control vs. intervention), but there was a significant effect of sex on children's PA during outdoor free play at baseline(p < 0.05). Similarly, there was no effect of group on PA during days with the movement program(intervention vs. outdoor free play) at either time point, but boys were more active than girls at the late assessment(p < 0.05). Last, children in the intervention engaged in more PA while participating in the intervention toward the end of the intervention than at the beginning.Conclusion: The 5-week motor skill intervention was effective at improving preschoolers' motor skills and rates of change in motor skills were higher for children who completed the intervention compared with children in the control group. Preschoolers in the intervention did demonstrate PA changes while participating in the intervention, but these changes did not translate outside of the intervention setting.

A mixed-studies systematic review and meta-analysis of school-based interventions to promote physical activity and/or reduce sedentary time in children

Purpose:The aim of this mixed-studies systematic review was to ascertain the effectiveness of school-based interventions in increasing physical activity(PA) and/or reducing sedentary time(ST) in children aged 5-11 years,as well as to explore their effectiveness in relation to categories of the theory of expanded,extended,and enhanced opportunity(TEO).Methods:Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA) guidelines,5 databases were searched using predefined search terms.Following title and abstract screening of 1115 records,the removal of duplicates(n=584) and articles that did not meet the inclusion criteria agreed to a priori(n=419) resulted in 112 records that were full-text screened.Two independent reviewers subsequently used the mixed-methods appraisal tool to assess the methodological quality of 57 full-text studies that met the inclusion criteria after full-text screening.The interventions were summarised using the TIDierR checklist and TEO.The strength of evidence was determined using a 5-level rating system utilising a published decision tree.Results:Overall evidence ratings for interventions implemented within school settings were:no evidence of effects on moderate-to-vigorous physical activity(MVPA) and inconclusive evidence of effects on sedentary time.In relation to the TEO,expansion of PA appeared to be the most promising intervention type for MVPA,with moderate evidence of effect,whereas extension and enhancement of PA opportunity demonstrated no evidence of effect.A critical issue of possible compensatory behavior was identified by analysis of intervention effect in relation to PA measurement duration;when studies measured changes in PA during the actual intervention,there was moderate evidence of effect,whereas those that measured changes in PA during the school day presented inconclusive evidence of effect,and those that measured changes in PA over a whole day yielded no evidence of effect.Two meta-analyses of those studies using a whole-day accelerometer measure for MVPA or ST showed a significant but moderate effect for MVPA(effect size=0.51;95% confidence interval(CI):0.02-0.99) and a large but nonsignificant effect for ST(effect size=1.15;95%CI:-1.03 to 3.33);both meta-analyses demonstrated low precision,considerable inconsistency,and high heterogeneity.Conclusion:The findings have important implications for future intervention research in terms of intervention design,implementation,and evaluation.

Daily Activities and Sleep Durations of Patients with Ischemic Heart Disease Who Were Discharged to Their Homes after Elective Percutaneous Coronary Intervention

The purpose of this study was to examine the relationship between daily activities and sleep durations for patients following elective percutaneous coronary intervention (ePCI) and diagnosed with ischemic heart disease (IHD) after discharge to their homes. The actigraph data were used to collect data from twenty five patients. The duration of night-time sleep (minutes from the start to end of night-time) and actual night-time sleep duration (total sleep duration excluding wake-up durations of night-time) on the seventh day after discharge were divided into three groups;less than 360, 360 to 480, and more than 480 minutes (short, optimal and long respectively). Subsequently, among the three groups of patients, the data were analyzed by Kruskal Wallis H-test with multiple comparison procedures using the Scheffé-test in order to compare differences in daytime activity items at seven days after discharge from the hospital. Total daytime nap duration (p p p p < 0.05). However, the duration of night-time sleep and daytime activity did not significantly differ. If actual night-time sleep duration is improved from 360 to 480 minutes, daytime nap could potentially be decreased. Determining objective sleep conditions for patients and treating sleep disorders may improve overall patient health, facilitating appropriate sleep and wake rhythms.

Effects of positive psychological control intervention on sleep and psychology of officers and soldiers working at sea

BACKGROUND The working environment of submarine crews is also very special.They are in a closed,high-temperature,high-noise,high-vibration and narrow working and living space for a long time,and they suffer from physical discomfort caused by seasickness,which will affect the mental health of officers and soldiers.American psychologists have achieved positive results in psychological resilience training for officers and soldiers from the perspective of positive psychology.At present,there are few reports on the correlation between psychological resilience in the field of domestic research on submarine crew psychology,and it is necessary to conduct further research.METHODS A total of 121 soldiers working in a confined space of a large ship were randomly divided into an experimental group and a control group.The 50 soldiers in the experimental group were given a training course intervention,while the 71 soldiers in the control group did not receive any intervention measures.The Pittsburgh Sleep Quality Index,Psychological Resilience Scale,military Psycho-logical Stress Self-Assessment Questionnaire,and General Self-Efficacy Scale scores were compared before and 6 months after the intervention.RESULTS Under the positive psychological control intervention,except for sleep efficiency(P=0.05),the difference between the remaining dimensions of the Pittsburgh Sleep Quality Index scores and the total scores of the experimental group compared with the control group was statistically significant(P<0.05);the assessment of the psychological condition showed that,in addition to the Psychological Stress Self-assessment Questionnaire for Military Personnel scores(P=0.05),the scores of the Mental Toughness Scale(Dispositional Resilience Scale Resilience II)in the experimental group,General Self-Efficacy Scale scores were statistically significant(P<0.05)compared to pre-intervention.CONCLUSION Positive psychological intervention and control can improve the sleep state and psychological state of officers and soldiers working in confined space at sea.

Interventional effect of phycocyanin on mitochondrial membrane potential and activity of PC12 cells after hypoxia/reoxygenation

BACKGROUND： Phycocyanin can relieve decrease of mitochondrial membrane potential through reducing production of active oxygen so as to protect neurons after hypoxia/reoxygenation. OBJECTIVE： To observe the effect of phycocyanin on activity of PC12 cells and mitochondrial membrane potential after hypoxia/reoxygenation. DESIGN： Randomized controlled study SETTING ： Cerebrovascular Disease Institute of Affiliated Hospital, Medical College of Qingdao University MATERIALS： The experiment was carried out at the Key Laboratory of Prevention and Cure for cerebropathia in Shandong Province from October to December 2005. PC12 cells, rat chromaffin tumor cells, were provided by Storage Center of Wuhan University; phycocyanin was provided by Ocean Institute of Academia Sinica; Thiazoyl blue tetrazolium bromide （MTT） and rhodamine 123 were purchased from Sigma Company, USA; RPMI-1640 medium, fetal bovine serum and equine serum were purchased from Gibco Company, USA. METHODS： ① Culture of PC12 cells： PC12 cells were put into RPMI-1640 medium which contained 100 g/L heat inactivation equine serum and 0.05 volume fraction of fetal bovine serum and incubated in CO2 incubator at 37℃. Number of cells was regulated to 4 × 10^5 L 1, and cells were inoculated at 96-well culture plate. The final volume was 100μL. ② Model establishing and grouping： Cultured PC12 cells were randomly divided into three groups： phycocyanin group, model control group and non-hypoxia group. At 24 hours before hypoxia, culture solution in phycocyanin group was added with phycocyanin so as to make sure the final concentration of 3 g/L , but cells in model control group did not add with phycocyanin. Cells in non-hypoxia group were also randomly divided into adding phycocyanin group （the final concentration of 3 g/L） and non-adding phycocyanin group. Cells in model control group and phycocyanin group were cultured with hypoxia for 1 hour and reoxygenation for 1, 2 and 3 hours; meanwhile, cells in non-hypoxia group were cultured with oxygen and were measured at 1 hour after hypoxia/reoxygenation. ③ Detecting items： At 1, 2 and 3 hours after reoxygenation, absorbance （A value） of PC12 cells was measured with MTT technique so as to observe activity and quantity of cells. Fluorescence intensity of PC12 cells marked by rhodamine 123 was measured with confocal microscope in order to observe changes of mitochondrial membrane potential. MAEN OUTCOME MEASURES： Comparisons between quantity and activity of PC12 cells and mitochondria membrane potential at 1, 2 and 3 hours after reoxygenation. RESULTS： ① Effect of phycocyanin on quantity and activity of PC12 cells： A value was 0.924±0.027 in adding phycocyanin group and 0.924±0.033 in non-adding phycocyanin group. A value was lower in model control group and phycocyanin group than that in non-hypoxia group at 1, 2 and 3 hours after reoxygenation （0.817±0.053, 0.838±0.037, 0.875±0.029; 0.842±0.029, 0.872±0.025, 0.906±0.023, P 〈 0.05）. A value was higher in phycocyanin group than that in model control group at 1, 2 and 3 after culture （P 〈 0.05）. With culture time being longer, A value was increased gradually in phycocyanin group and model control group after reoxygenation （P 〈 0.05）. ~ Effect of phycocyanin on mitochondrial membrane potential of PC12 cells： Fluorescence intensity was 2.967±0.253 in adding phycocyanin group and 2.962±0.294 in non-adding phycocyanin group. Fluorescence intensity was lower in model control group and phycocyanin group than that in non-hypoxia group at 1, 2 and 3 hours after hypoxia/reoxygenation （1.899±0.397, 2.119±0.414, 2.287±0.402; 2.191±0.377, 2.264±0.359, 2.436±0.471, P 〈 0.05）; but it was higher in phycocyanin group than that in model control group at 1, 2 and 3 after reoxygenation （P 〈 0.05）. With culture time being longer, fluorescence intensity was increased gradually in phycocyanin group and model control group after reoxygenation （P 〈 0.05）. CONCLUSION： Phycocyanin and reoxygenation can protect PC12 cells after hypoxia injury through increasing mitochondrial membrane potential and cellular activity, and the effect is improved gradually with prolonging time of reoxygenation.

Adolescents’ perspectives on a school-based physical activity intervention:A mixed method study

Purpose'. To examine adolescent experiences and perspectives of the GoActive intervention (ISRCTN31583496) using mixed methods processevaluation to determine satisfaction with intervention components and interpret a*dolescents experiences of the intervention process in order toprovide insights for future intervention design.Methods'. Participants (n = 1542;13.2 土 0.4 years, mean 土 SD) provided questionnaire data at baseline (shyness, activity level) and post-intervention(intervention acceptability, satisfaction with components). Between-group differences (boys vs. girls and shy/inactive vs. others) weretested with linear regression models, accounting for school clustering. Data from 16 individual interviews (shy/inactive) and 11 focus groupswith 48 participants (mean = 4;range 2—7) were thematically coded. Qualitative and quantitative data were merged in an integrative mixedmethods convergence matrix, which denoted convergence and dissonance across datasets.Results'. Effect sizes for quantitative results were small and may not represent substantial between-group differences. Boys (vs. girls) preferredclass-based sessions (0 = 0.2, 95% confidence interval (CI): 0.1—0.3);qualitative data suggested that this was because boys preferred competition,which was supported quantitatively (0 = 0.2, 95%CI: 0.1-0.3). Shy/inactive students did not enjoy the competition (0 = -0.3, 95%CI:—0.5 to —0.1). Boys enjoyed trying new activities more (0 = 0.1, 95%CI: 0.1 -0.2);qualitative data indicated a desire to try new activities acrossall subgroups but identified barriers to choosing unfamiliar activities with self-imposed choice restriction leading to boredom. Qualitative datahighlighted critique of mentorship;adolescents liked the idea, but older mentors did not meet expectations.Conclusion. We interpreted adolescent perspectives of intervention components and implementation to provide insights into future complexinterventions aimed at increasing young people's physical activity in school-based settings. The intervention component mentorship was liked inprinciple, but implementation issues undesirably impacted satisfaction;competition was disliked by girls and shy/inactive students. The resultshighlight the importance of considering gender differences in preference of competition and extensive mentorship training.

"CF chatters": the development of a theoretically informed physical activity intervention for youth with cystic fibrosis

Despite the benefits of physical activity for youth living with cystic fibrosis (CF), the majority of patients are insufficiently active to meet physical activity recommendations. Existing physical activity interventions are atheoretical and tend to prescribe standardized exercise regimes which are often not appealing for children and compromise long term adherence. Following recent calls for counselling based physical activity approaches in the CF population, this study describes the development of a theoretically informed, parent-mediated, behavioural counselling intervention for CF youth―“CF Chatters”. We first a) describe the development of a grounded theory of physical activity in youth with CF;b) explain how this theory informed the development and implementation of the CF Chatters program and c) reflect on the findings of our pilot intervention using a case study research design. CF Chatters participants demonstrated self reported increases in physical activity and quality of life. While further development and more robust objective measures are needed to extend this investigative pilot work, our findings suggest that behavioural counselling is an effective modality for enhancing physical activity participation and quality of life in this life limited group of children and youth.

School-based physical activity interventions for children and youth:Keys for success

Given the rising trend in obesity in children and youth and age-related decline in moderate-to-vigorous-intensity physical activity(MVPA)in several Western,African,and Asian-Pacific countries^1 and strong evidence that past physical activity(PA)interventions have had only a small effect on children’s and youth’s overall activity levels,~2it is important to clarify whether school-based PA interventions warrant resource allocation.Schools represent an accessible and cost-effective

Physical activity levels and predictors in patients following percutaneous coronary intervention: a cross-sectional study

Objective: To examine physical activity(PA) of post-percutaneous coronary intervention(PCI) patients and explore the demographic, clinical, and social psychological characteristics associated with PA levels. Methods: A total of 246 post-PCI patients from the Peking University Third Hospital in Beijing, China, were included in this crosssectional study through convenience sampling. Data were collected from a self-repor ted questionnaire. PA was categorized into low, moderate, or high levels. The ordinal multinomial logistic regression model was used to estimate the relationship among demographic, medical, and psychosocial characteristics. Results: The overall prevalence of low, moderate, and high PA was 20%, 70%, and 10%, respectively. For the domain-specific PA patterns, most par ticipants took par t in leisure-time PA(84.5%);walking was the most common PA. Increased motivation and selfefficacy, lower monthly income, and unemployment were predictors of high PA. Conclusions: PA levels in post-PCI patients was not optimal, and leisure-time PA had the highest par ticipation rate. Analyses of influencing factors can provide medical staff and health workers information to focus on high-risk groups and introduce more tailored interventions. Future studies can explore more regions, and ecological models can be introduced to study more influencing factors.

Active treatments are a rational approach for hepatocellular carcinoma in elderly patients

AIM: To determine whether an active intervention is beneficial for the survival of elderly patients with hepa-tocellular carcinoma (HCC). METHODS: The survival of 740 patients who received various treatments for HCC between 1983 and 2011 was compared among different age groups using Cox regression analysis. Therapeutic options were principal-ly selected according to the clinical practice guidelines for HCC from the Japanese Society of Hepatology. The treatment most likely to achieve regional control capa-bility was chosen, as far as possible, in the following order: resection, radiofrequency ablation, percutaneous ethanol injection, transcatheter arterial chemoembo-lization, transarterial oily chemoembolization, hepatic arterial infusion chemotherapy, systemic chemotherapy including molecular targeting, or best supportive care.Each treatment was used alone, or in combination, with a clinical goal of striking the best balance be-tween functional hepatic reserve and the volume of the targeted area, irrespective of their age. The percent survival to life expectancy was calculated based on a Japanese national population survey. RESULTS: The median ages of the subjects during each 5-year period from 1986 were 61, 64, 67, 68 and 71 years and increased significantly with time (P<0.0001). The Child-Pugh score was comparable among younger (59 years of age or younger), middle-aged (60-79 years of age), and older (80 years of age or older) groups (P=0.34), whereas the tumor-node-metastasis stage tended to be more advanced in the younger group (P=0.060). Advanced disease was significantly more frequent in the younger group compared with the middle-aged group (P=0.010), whereas there was no difference between the middle-aged and elderly groups (P=0.75). The median sur-vival times were 2593, 2011, 1643, 1278 and 1195 d for 49 years of age or younger, 50-59 years of age, 60-69 years of age, 70-79 years of age, or 80 years of age or older age groups, respectively, whereas the me-dian percent survival to life expectancy were 13.9%, 21.9%, 24.7%, 25.7% and 37.6% for each group, respectively. The impact of age on actual survival time was significant (P=0.020) with a hazard ratio of 1.021, suggesting that a 10-year-older patient has a 1.23-fold higher risk for death, and the overall survival was the worst in the oldest group. On the other hand, when the survival benefit was evaluated on the basis of per-cent survival to life expectancy, age was again found to be a significant explanatory factor (P=0.022); how-ever, the oldest group showed the best survival among the five different age groups. The youngest group revealed the worst outcomes in this analysis, and the hazard ratio of the oldest against the youngest was 0.35 for death. The survival trends did not differ substan-tially between the survival time and percent survival tolife expectancy, when survival was compared overall or among various therapeutic interventions. CONCLUSION: These results suggest that a thera-peutic approach for HCC should not be restricted due to patient age.

Scoping review on health-related physical fitness in patients with inflammatory bowel disease:Assessment,interventions,and future directions

BACKGROUND Reaching the Selecting Therapeutic Targets in Inflammatory Bowel Disease-II(STRIDE-II)therapeutic targets for inflammatory bowel disease(IBD)requires an interdisciplinary approach.Lifestyle interventions focusing on enhancing and preserving health-related physical fitness(HRPF)may aid in improving subjective health,decreasing disability,or even controlling inflammation.However,ambiguity remains about the status and impact of HRPF(i.e.body composition,cardiorespiratory fitness,muscular strength,muscular endurance,and flexibility)in IBD patients,hindering the development of physical activity and physical exercise training guidelines.AIM To review HRPF components in IBD patients and the impact of physical activity and physical exercise training interventions on HRPF.METHODS A systematic search in multiple databases was conducted for original studies that included patients with IBD,assessed one or more HRPF components,and/or evaluated physical activity or physical exercise training interventions.RESULTS Sixty-eight articles were included.No study examined the complete concept of HRPF,and considerable heterogeneity existed in assessment methods,with frequent use of non-validated tests.According to studies that used gold standard tests,cardiorespiratory fitness seemed to be reduced,but findings on muscular strength and endurance were inconsistent.A limited number of studies that evaluated physical activity or physical exercise training interventions reported effects on HRPF,overall showing a positive impact.CONCLUSION We performed a scoping review using a systematic and iterative approach to identify and synthesize an emerging body of literature on health-related physical fitness in patients with IBD,highlighting several research gaps and opportunities for future research.Findings of this review revealed a gap in the literature regarding the accurate assessment of HRPF in patients with IBD and highlighted important methodological limitations of studies that evaluated physical activity or physical exercise training interventions.This scoping review is a step towards performing studies and systematic reviews in the future,which was not possible at present given the heterogeneity in endpoints and designs of the available studies on this topic.Future well-designed studies are required to determine the optimal training paradigm for improving HRPF in patients with IBD before guidelines can be developed and integrated into the therapeutic strategy.

Intervention Effects of the School-Based Health Promotion Program“Join the Healthy Boat”on Motor Abilities of Children with Migration Background

Purpose: Motor abilities of migrant children show worse performance compared with children without migration background. This study investigated whether a one-year intervention, which aimed to increase physical activity (PA), could influence the motor performance of these children positively. Methods: A sub-sample of 525 migrant children (7.1 ± 0.7 years;48.6% male), participated in the study and included an intervention (IG) and control group (CG). The Dordel-Koch-Test was used to assess motor performance. An exploratory factor analysis was performed. Differences between IG and CG were examined using ANCOVA. Results: Boys in the IG showed a significant improvement in the conditional skills (F(1, 201) = 8.02, p ≤ 0.005) and girls showed a tendency towards better results. Additionally, girls showed a significant improvement in flexibility (F(1, 226) = 10.72, p ≤ 0.01) compared with the CG. Conclusion: The intervention affects parts of motor skills of migrant children significantly. Future interventions should aim at a target-group-specific promotion to get a holistic improvement in their motor abilities.

Healing Dysfunctional Identity: Bridging Mind-Body Intervention to Brain Systems

In this paper, we aim to use an innovative model to integrate applied work on a fast-acting mind-body intervention, Mind-Body Bridging (MBB), with theoretical work based on psychology and neuroscience. In an affect-object generative inference and regulation (AGIR) model, we propose that functional dynamics between two systems, the affect-object thought generation system and the cognitive control system, can guide an individual to achieve homeostasis within self and harmonious relationships with others. We used Neurosynth (www.neurosynth.org), an automated meta-analysis database, to identify potential brain substrates underlying the key components in the AGIR model. Based on the findings, some brain regions are implicated as the key cortical substrates in this model, corroborating our central hypothesis that a hallmark of mind-body wellbeing can be characterized as a low-frequency anti-correlantion between 1) the cognitive control system including the dorsal anterior/middle cingulate cortex, and 2) the affect-object thought generation system including the ventromedial prefrontal cortex and posterior cingulate cortex. MBB provides an efficient strategy for responding to and dissolving a fundamental problem that impairs mind-body wellbeing, i.e., unrealistic identity-grasping consisting of self-centered embodied expectations of self and others. We demonstrated how theoretical and applied work could be integrated by drawing evidence from the neuroscience literature to support the AGIR model, and then we applied the AGIR model to elucidate how MBB might work.

Does a School-Based Lifestyle Intervention Program Impact Food Intake, Physical Activity, and Nutrition Knowledge of Adolescents: A Pilot Study

Non-communicable diseases (NCDs) are on the rise worldwide and in developing countries like Botswana. Unhealthy eating habits and lack of proper nutrition knowledge cause non-communicable diseases and affect adolescents. It is in adolescence that eating habits are formed that persist till adulthood. Lifestyle interventions are needed to curb NCDs in adolescents. This paper reports the findings of a study that aimed to validate a lifestyle intervention program and its effect on food intake, physical activity, and nutrition knowledge. It was a clustered randomized control trial study conducted in four (4) junior secondary schools. There were 46 participants, 21 in the control and 25 in the intervention arm, who were blindly assigned to each arm by a statistician. Information and skills on nutrition were imparted using the Information, Motivation, and Behavioral Skills model. The program was implemented for eight (8) weeks hourly after school. A questionnaire was used to collect data pre- and post-intervention. Number, proportion, percentage, and independent t-test (mean and SD or median and IQR, p-value) were calculated using numerical and categorical data. The findings showed that the lifestyle intervention was valid, and there was a slight decrease in the intake of sweets among participants in both trial arms (p = 0.066). There was no significant difference in terms of food intake. Only a small number of participants still ate a few fruits, and there was no change in vegetable intake in both trial arms (p = 0.641). There was no change in the intake of fried foods in both trail arms (p = 0.402). Regarding nutrition knowledge, there was a slight significant difference of p = 0.079 between the trial arms. Though the effect of the lifestyle intervention program was not statistically significant, the results are promising, especially if the duration could be increased to a longer period and a larger sample size included.
