Participatory developed school-based interventions targeting physical activity and sedentary behaviour among children and adolescents: A scoping review.

A significant number of children and adolescents are insufficiently physically active and have a sedentary lifestyle, which is associated with adverse health outcomes, necessitating effective interventions. Using a participatory approach, which engages youth in intervention development, may enhance intervention effectiveness, as such interventions are believed to be more tailored to the needs of the target group. This scoping review aimed to provide an overview of the results of process and effect evaluations of studies that developed school-based physical activity and/or sedentary behaviour interventions using a participatory approach among children and adolescents. Six databases (MEDLINE, Embase, Web of Science, CENTRAL (Cochrane Central Register of Controlled Trials), Scopus and SPORTDiscus) were searched. Studies were included when they evaluated the participatory process, intervention implementation or health-related intervention effects. A quality assessment was completed using two QualSyst checklists. Extracted data included characteristics of studies, interventions, and participatory processes; characteristics of participants from whom data were collected; outcomes measured and measurement methods used; and key findings. Twenty-five papers, covering 18 original studies, were included. Studies suggested that participatory processes were generally perceived positively, resulting in pupils feeling empowered, experiencing ownership and gaining certain skills. Participatory developed interventions also seemed to be generally well received, although the intervention dose delivered and intervention reach seemed to vary between studies. Finally, studies generally tended to report no effects on health. Although a participatory approach could be promising in empowering pupils and promoting intervention acceptance, apparent differences in intervention implementation and limited effectiveness highlight the need to enhance participatory processes and intervention effectiveness.

School Poverty Level Moderates the Effectiveness of a Physical Activity Intervention.

To explore whether school poverty level and funding modified the effectiveness of an evidence-based Comprehensive School Physical Activity Program called Health Empowers You! implemented in elementary schools in Georgia. Secondary data analysis of a multi-level, cluster-randomized controlled trial. 40 elementary schools in Georgia in 2018-2019. 4th grade students in Georgia. Intervention schools implemented the Health Empowers You! program to increase school-day physical activity. The outcome was average daily moderate-to-vigorous physical activity, school free-reduced price lunch (FRPL) percentage and per pupil expenditures were effect modifiers. Separate linear mixed regression models estimated the effect of the intervention on average daily moderate-to-vigorous physical activity, with interaction terms between intervention status and (1) school FRPL percentage or (2) per pupil expenditures. The effect of the intervention was significantly higher in schools with higher FRPL percentage (intervention*school % FRPL β (95% CI): .06 (.01, .12)), and was modestly, but not statistically significantly, higher in schools with lower per pupil expenditures. Findings support the use of the Health Empowers You! intervention, which was effective in lower income schools, and may potentially reduce disparities in students' physical activity levels.

Potential Mechanism of Perillaldehyde in the Treatment of Nonalcoholic Fatty Liver Disease Based on Network Pharmacology and Molecular Docking

Non-alcoholic fatty liver disease (NAFLD) is one of the most common chronic metabolic liver diseases worldwide. Perillaldehyde (4-propyl-1-en-2-ylcyclohexene-1-aldehyde, PA) is a terpenoid compound extracted from Perilla, which has effective pharmacological activities such as anti-inflammatory, antidepressant, and anticancer. This study aimed to explore the pharmacological effects of PA in intervening with NAFLD and reveal its potential mechanisms. Firstly, we identified the core targets of PA intervention therapy for NAFLD through network pharmacology and molecular docking techniques. After that, in vitro animal experiments such as H&E and Masson staining, immunofluorescence, immunohistochemistry, and western blot were conducted to validate the results network effectively pharmacology predicted. Network pharmacology analysis suggested that PPAR-α may be the core target of PA intervention in NAFLD. H&E and Masson staining showed that after low-dose (50mg/kg) PA administration, there was a noticeable improvement in fat deposition in the livers of NAFLD mice, and liver tissue fibrosis was alleviated. Immunohistochemical and immunofluorescence analysis showed that low dose (50mg/kg) PA could reduce hepatocyte apoptosis, decrease the content of pro-apoptosis protein Bax, and increase the expression of anti-apoptosis protein Bcl-2 in NAFLD mice. Western blot results confirmed that low-dose (50mg/kg) PA could increase the expression of PPAR-α and inhibit the expression of NF-κB in NAFLD mice. Our study indicated that PA could enhance the activity of PPAR-α and reduce the level of NF-κB in NAFLD mice, which may positively affect the prevention of NAFLD.

A look into the cancer continuum for the development of a physical activity intervention: qualitative investigation of the physical activity experiences and preferences of female cancer survivors.

Clinical guidelines recommend cancer survivors (i.e., people with a cancer diagnosis) engage in regular physical activity (PA) during and post treatment, yet most do not. Additionally, PA promotion for cancer survivors has primarily focused on post treatment, calling for an understanding of PA promotion during treatment. This study explores the PA experiences and preferences of both in-treatment and post-treatment breast and gynecologic cancer survivors (BGCS) to inform the design of a PA intervention. Semi-structured interviews were conducted with postmenopausal women aged ≥ 50years, diagnosed with breast or gynecological cancer (stages 1-3), who were undergoing, or recently completed (12 to 24months) chemotherapy and/or primary treatment. Interviews were audio-recorded and transcribed verbatim. Thematic analysis was used to explore themes. Participants (N = 26; Mage: 63.9years) had a breast (92.3%) and gynecologic (7.7%) cancer diagnosis and 46.2% (n = 12) were in treatment whereas 53.8% (n = 14) were post treatment. BGCS experienced several side effects of cancer treatment and both groups felt PA was an important goal. In-treatment BGCS focused on managing side effects (e.g., fatigue) and recognized energy fluctuated around treatments, making those periods less ideal for PA. In-treatment BGCS strongly endorsed a flexible, at-home intervention. Post-treatment BGCS emphasized recovery and relapse prevention, also favoring at-home, flexible interventions but showing greater interest towards support groups to aid with their recovery journey. Preferred activities included walking, dancing, and muscle-strengthening. Findings highlight the unique challenges postmenopausal BGCS face in participating in PA, especially in-treatment, emphasizing the importance of a tailored PA intervention.

Willingness of Women at Increased Risk of Breast Cancer to Participate in Prevention Trials.

The factors affecting women's willingness to participate (WTP) in breast cancer (BC) prevention trials are poorly understood. This study aimed to identify the characteristics of interventions associated with a higher WTP among high BC risk women. Women who self-identified as being at an increased risk of BC were recruited to a cross-sectional study of WTP in BC prevention trials. Responses were dichotomized into more willing (a lot and moderately) and less willing (some, a little, and not at all), and responses were compared by patient characteristics and intervention type. Of 143 participants, 81.2% (116) completed ≥30% of a Likert-type scale questionnaire on WTP in various intervention types for BC prevention. Overall, WTP in BC prevention studies was high, with 82.7% more willing, including 69.0% and 70.7%, respectively, for unspecified physical activity and dietary interventions. WTP differed significantly by the duration of diet-based and physical activity behavior change interventions: decreasing with 12- versus 3-month diet-based interventions (P < .0001) and decreasing for 1 hour versus 30 minutes of low-intensity exercise/day (P < .0001). For interventions involving medication, only 18.1% expressed being more willing to participate, and WTP decreased significantly when side effects were presented. WTP was influenced by BC risk gene mutation status, with WTP among gene carriers higher compared with nongene carriers (52.6% v 30.2%, P = .018). WTP in BC prevention trials was the highest for women with known genetic risk and for interventions involving a behavior change. Medications with side effects had the lowest WTP. For behavior change, WTP was negatively influenced by intervention duration beyond a few months, indicating that individual perception of BC risk and inconvenience strongly influence WTP.

GERONTOMOTRICIDADE:A PRÁTICA DA ATIVIDADE FÍSICA PARA UM ENVELHECIMENTO SAUDÁVEL

Aging is a phenomenon already identified in the last century, being called countless times as a misfortune, which resulted in some discussions, because if the years of life were prolonged, we should also foresee that there were no limitations in the quality of life, given that Aging is one of the greatest feats of modern humanity. Given this, the general objective of this study is to relate the practice of Gerontomotricity in the process of encouraging physical activity with a focus on the healthy aging process. To that end. we list the following specific objectives: identify the main changes resulting from the aging process that directly affect the functional autonomy of the elderly; evaluate the intervention of physical activity on the psychomotricity of the elderly and relate the benefits of the activities developed by the Gerontomotricity program in implementing a healthy aging process. The research is a literature review with a descriptive aspect and a qualitative approach. In the review, the following inclusion/exclusion factors were considered: articles published between 2020 and 2024 and that worked on the topic: Gerontomotricity and/or physical activities for the elderly. The research data revealed that active elderly people have less impaired motor skills, which results in healthy aging, with a great improvement in the ability to carry out their daily activities alone, which significantly reflects on the daily activities of the elderly. It is concluded, therefore, that the practice of continuous physical activities generates a noticeable improvement in the quality of life of the elderly, as it is combined with a set of methods with the objective of evaluating and determining the most recommended exercises for each individual, considering them. If all its particularities and aiming to meet the needs arising from the changes caused by the aging process, it results in significant changes in life, in the elderly gaining autonomy and coexistence with others.

Fit club: Outcomes from 35-minute daily exercise program for autistic adolescents

BackgroundAutistic children and adolescents have academic performance challenges and are often reluctant to participate in physical activities. Executive function (EF) abilities generally remain stable or worsen as autistic children get older and obesity and lack of physical fitness are frequent concerns experienced by these individuals. Finding ways to address these concerns has the potential to improve outcomes in autistic youth. MethodWe conducted a 12-month, repeated-measures study to examine the effectiveness of a mandatory 35-minute daily school physical activity intervention involving low to moderate exertion for autistic adolescents (n = 29). Changes in fitness, EF, social responsiveness, and restrictive and repetitive behaviors were examined. ResultsSignificant improvements were seen in fitness, EF areas (specifically cognitive flexibility and planning/organizing), restrictive and repetitive behaviors and social responsiveness. ConclusionFindings suggest that participation in a mandatory daily 35-minute physical activity program with low to moderate exertion is feasible and may contribute to improved EF, fitness, restricted and repetitive behavior, and social responsiveness in autistic adolescents.

Toward a whole-of-virtual school framework for promoting student physical activity: a scoping review protocol

BackgroundThe advent of full-time virtual schooling presents unique challenges and opportunities for the promotion of physical activity (PA) among children and adolescents. Despite the recognized benefits of PA as an essential component for combating non-communicable diseases and ensuring holistic development, there is a notable gap in understanding how to effectively integrate PA within the digital learning environments of full-time virtual schools. Current efforts to promote student PA are targeted for implementation exclusively in contexts characterized by physical school campuses that are bound to their surrounding local communities. This is problematic given the digital, widely distributed, and contextually unmoored nature of virtual schooling. Our aim in this scoping review is to advance research on whole-of-school physical activity promotion within full-time virtual schools by examining the published literature on whole-of-school PA promotion within full-time virtual schools. Specifically, this review will map the literature, consolidate knowledge claims and practical implications, and identify evidence gaps that merit further investigation.Methods/designThis review will be conducted using evidence-informed scoping review methodology and reporting guidelines. Articles will be included if they are peer-reviewed English-language research, commentary, practical, or grey literature and relate to the participation, support, design, development, and/or provision of remote online PA interventions delivered through primary/elementary and/or secondary/middle school/high schools. Searches will be conducted in PsycInfo, ERIC, SportDiscus, and Web of Science. Additional hand-searching, reference scans, and grey literature searches will also be performed. Two trained research assistants will independently complete study screening and selection and data charting with guidance from a senior author. Charted data will be displayed in table form, and depending on the results, data will also be synthesized through qualitative content analysis using the Active Schools guiding framework as an analytical and interpretive lens.DiscussionThis scoping review will serve as a guidepost for the application and advancement of research on whole-of-school PA promotion through full-time virtual schools. The results will address the increased importance of equitable online learning and PA promotion due to the expanding virtual education landscape, with implications for public health and education policy.Systematic review registrationOpen Science Framework: https://osf.io/f6wau/.

A Tailored Postpartum eHealth Physical Activity Intervention for Individuals at High Risk of Postpartum Depression-the POstpartum Wellness Study (POW): Protocol and Data Overview for a Randomized Controlled Trial.

Postpartum depression (PPD) is associated with significant health consequences for the parent and child. Current recommendations for PPD prevention require intense health care system resources. Evidence-based interventions for PPD prevention that do not further burden the health care system are needed. Evidence suggests that physical activity (PA) can generally reduce depressive symptoms. Technology-based interventions may help decrease common barriers to PA. This study aims to report the protocol and provide a data overview of the POstpartum Wellness study (POW)-an effectiveness trial evaluating whether an eHealth PA intervention tailored for postpartum individuals increased PA and decreased depressive symptoms among individuals at high PPD risk. This remote parallel-group randomized controlled trial included postpartum individuals with a history of depression or at least moderate current depressive symptoms not meeting the PPD diagnostic threshold and with low PA levels from an integrated health care delivery system. Participants were randomized to an eHealth PA intervention or usual care. The intervention group received access to a library of web-based workout videos designed for postpartum individuals, which included interaction with their infants. At baseline and follow-up (3 and 6 months), PA was measured using questionnaires and a wrist-worn accelerometer. Depressive symptoms were measured using the Patient Health Questionnaire-8 (PHQ-8). Data were collected to assess exploratory outcomes of sleep, perceived stress, anxiety, parent-infant bonding, and infant development. The study was funded in January 2020. Participants were enrolled via REDCap (Research Electronic Data Capture) or telephonically between November 2020 and September 2022; data collection ended in April 2023. Randomized participants (N=99) were 4 months post partum at baseline with moderately severe depressive symptoms (mean PHQ-8 score 12.6, SD 2.2). Intervention (n=50) and usual care (n=49) groups had similar sociodemographic characteristics, months post partum, baseline depressive symptoms, number of children at home, and prepregnancy PA levels. Retention in assessments was ≥66% for questionnaires and ≥48% for accelerometry, with modest differences by group. At 3-month follow-up, 73 of 99 (74%) participants (intervention: 35/50, 70%; usual care: 38/49, 78%) completed questionnaires; 53 of 99 (54%) wore the accelerometer for 7 days (27 of 50 (54%) intervention, 26 of 49 (53%) usual care). At 6-month follow-up, 66 of 99 (67%) participants (30 of 50 (60%) intervention, 36 of 49 (73%) usual care) completed questionnaires and 43 of 99 (43%) wore the accelerometer for 7 days (21 of 50 (42%) intervention, 22 of 49 (45%) usual care). Data analysis is completed, and a manuscript with these findings is currently under review for publication. The POW trial evaluates the effectiveness of an eHealth PA intervention for improving depressive symptoms and increasing PA among postpartum individuals at high PPD risk. Results have implications for the design and delivery of behavioral interventions among vulnerable patients. ClinicalTrials.gov NCT04414696; https://clinicaltrials.gov/ct2/show/NCT04414696.

Effects of a Six-Month Physical Activity Program on Health Risk Factors and Body Composition Among Overweight and Obese Middle-Aged Adults

Introduction. Physical activity is vital for preventing and managing lifestyle-related diseases, which pose significant health and socio-economic challenges. This study aimed to evaluate the effects of a six-month supervised physical activity program on health risk factors and body composition in middle-aged individuals with overweight or obesity. Methods. The study involved 166 men and women aged 30 to 65 years, with a body mass index (BMI) ranging from 26 to 35 and moderate to severe health risks. Participants of the study were engaged in a six-month physical activity training program designed in accordance with World Health Organization guidelines. Comprehensive assessments were performed at baseline and after the intervention, including measurements of various anthropometric and body composition parameters, as well as evaluations of functional performance. Fitness tests were also conducted to assess participants’ physical capacity and to monitor improvements throughout the training period. Results. Baseline measures of body mass composition and age demonstrated a strong positive correlation with visceral fat rating (VFR) in both men (r = 0.364, p &lt; 0.001) and women (r = 0.420, p = 0.002). Following the six-month training program, participants exhibited an average improvement of 30% (p &lt; 0.001) in their Cooper endurance test results. The physical activity intervention positively impacted body mass index (BMI) and various body composition metrics, including fat mass, VFR, and muscle mass, across all participants and most subgroups (gender, BMI, and age). In males, training at higher maximum heart rate (HRmax) zones significantly contributed to a reduction in the percentage of fat mass (80–89% HRmax) and an increase in the percentage of muscle mass (70–79% and 80–89% HRmax). Conclusions. The study indicates that a six-month supervised physical activity program significantly improves health risk factors and body composition (visceral fat reduction and improvement in percent of fat and muscle mass) among middle-aged individuals with overweight or obesity. Therefore, we advocate for the integration of structured physical activity interventions into healthcare practices to effectively enhance health outcomes in this population.

Systematic review and meta-analysis on the effects of physical activity-based interventions on frailty status and clinical outcomes in adults with long-term cardiac conditions

Abstract Introduction Frailty is common in patients with long-term cardiac conditions and is associated with poor clinical outcomes, but limited treatment options are available. Previous studies investigating interventions for frailty have shown positive results with physical activity interventions, however, these studies were largely based on general elderly populations. Aim To assess the impact of physical activity-based interventions on frailty and clinical outcomes in frail patients with long-term cardiac conditions. Methods A systematic review and meta-analysis was conducted based on the PRISMA guideline, using Medline, Embase, CENTRAL, PEDro, CINAHL electronic databases for articles published between 2000 and 2023. Studies which recruited adults &amp;gt;18 years with long-term cardiac conditions (including angina, acute coronary syndrome (ACS), valve disease, heart failure (HF), atrial fibrillation, cardiac surgery and congenital heart disease) who underwent physical activity-based interventions were included. The primary outcome was change in frailty (measured using a validated tool) post intervention. We also assessed the effect of interventions on mortality and hospitalisation. Results We screened 2697 records and reviewed 91 full-text articles; 12 studies (14 articles) were included, involving 1394 patients. Median age of participants ranged from 64 to 82 years. Five studies recruited participants with HF, 3 evaluated participants post transaortic valve implantation, 3 recruited cardiac surgical patients and 1 study evaluated participants post ACS. Physical activity-based interventions were multi-domain, including a mixture of aerobic, strength, balance, endurance and respiratory muscle training; the majority (N=10) had individualised exercise prescription. Meta-analysis of 8 randomised controlled trials (RCTs) showed statistically significant improvement in frailty associated with physical activity-based interventions compared to controls [pooled standardised mean difference (95% CI) = -0.34 (-0.59 to -0.08), p = 0.01, I2 = 48%]. Seven RCTs evaluated change in frailty by short physical performance battery (SPPB). Meta-analysis of these studies showed a statistically significant improvement in SPPB associated with physical activity-based interventions compared to controls [pooled mean difference (95% CI) = 0.83 (0.31-1.34), p = 0.002, I2 = 49%]. (Figure) The magnitude of improvement in SPPB exceeded the minimally clinically significant improvement of 0.5. Three studies evaluated the effect of physical activity-based intervention on clinical outcomes, all of which showed neutral effect on mortality and hospitalisation. Conclusion Physical activity-based interventions in patients with frailty and long-term cardiac conditions were associated with significant improvement in frailty status, with neutral effect on mortality and hospitalisation. Figure: Meta-analysis of 7 RCTs assessing effect of physical activity-based interventions on SPPB

Physical Activity-Related Health Services in Germany: Relevance and Necessary Framework Conditions - a Position Paper of the DNVF Working Group Physical Activity-Related Health Services Research

Based on the relevance of an established and broad foundation of physical activity in healthcare, this position paper of the DNVF working group Physical Activity-Related Health Services research presents current conceptual approaches to physical activity-related health services in Germany and highlights the need for interprofessional and interdisciplinary approaches. Three central positions are outlined and elaborated in order to integrate the evidence on health benefits of physical activity and exercise more strongly into healthcare and to show that, against the background of the challenges in the German healthcare system, physical activity-related health services can make a cost-effective and high-quality contribution to improve healthcare. These three positions include 1) the integration of all professional groups involved in healthcare into physical activity-related health services, 2) the greater integration of physical activity professions and physical activity interventions into all healthcare contexts and 3) the systematic consideration of physical activity- and exercise-related expertise in clinical guidelines.

Impact of ‘10,000 Steps Duesseldorf’ after one year: Results of a controlled intervention study

Abstract Background Despite marked decreases in physical activity (PA) in Germany due to the pandemic, population-based intervention strategies to tackle this public health problem remain sparse. The 12-month PA intervention ‘10,000 Steps Duesseldorf’ was composed of multiple components: at individual level, website to self-monitor steps; organizational level, step count competitions; environmental level, city-wide media campaign to increase awareness regarding benefits of PA and street signage indicating walking routes. This study aimed to replicate a research trial from Belgium addressing two questions: (1) Do individuals located in the city that the intervention is implemented in (Duesseldorf) engage in more PA compared to individuals located in the control city (Wuppertal) after one year? (2) Is the proportion of those reaching 10,000 steps/day higher in the intervention than in the control city after the intervention? Methods To investigate intervention effects, PA was assessed via pedometers in two representative samples of adults aged 25-75 years in the cities of Duesseldorf (intervention) and Wuppertal (control) at baseline (April 2021 - March 2022) and one-year follow-up (May-November 2023). Baseline differences in socio-demographic and health-related variables between intervention and control were adjusted for in a propensity score model with matching weights. Results 627 adults participated in the study at baseline and 553 at follow-up (60% female, 60% intervention). The results of the propensity score analyses revealed that intervention participants walked 462 steps more (95% confidence interval: -146 to 1070) than controls at follow-up. However, the proportion of residents reaching 10,000 steps/day was comparable between intervention and control city after the intervention (26%, both cities). Conclusions Our results suggest an intervention effect on daily steps taken in Duesseldorf experiencing intervention activities compared to the control city after one year. Key messages • The complex PA intervention from Belgium was successfully adapted and implemented in Germany resulting in a higher level of daily steps taken in the intervention city (compared to control). • A limitation of the study is that the recruitment process was hampered by the ongoing pandemic, resulting in selection bias, i.e. already active individuals were more likely to enrol in the study.

Non-health-targeted promotions and step counts of smartphone-based mall walking program users

Abstract Background The COVID-19 pandemic changed lifestyles and raised concerns regarding physical inactivity among adults. Mobile health interventions for physical activity may be a potential solution. However, the effects may diminish over time. This study investigated whether incorporating non-health-targeted promotions into an existing mobile health-walking program could stimulate users to walk. Methods We used nationwide cohort data of smartphone users participating in a shopping mall walking program in Japan. We focused on existing users registered in the program until October 31, 2022. A Japanese anime tie-in promotion was conducted by the shopping mall company from December 3 to 25, 2022, offering additional rewards alongside the regular program. We collected step count records of existing users 1 month before and after (November 1 to December 2, 2022, and December 26, 2022 to January 31, 2023, respectively), and during the promotion period. Propensity score matching was applied to ensure balance in the baseline characteristics of existing users in terms of gender, age, and pre-promotion program participation frequency. Next, we analyzed the association between participation in the promotion program and the average daily step counts during and after the promotional period using mixed effects models for repeated measures, while adjusting for the same covariates. Results Among the 18,156 users included in the study, 13,386 (73.7%) were women, with a mean (SD) age of 45.2 (12.7) years, and a mean (SD) pre-promotion program participation frequency of 9.7 (9.6) per month. During the promotion period, the participants walked 87 (95% CI: 50-125) more steps per day than non-participants, after adjusting for covariates. No clear association was observed 1 month post-promotion. Conclusions These findings indicate that non-health-targeted promotions may be short-term motivators for existing app users to walk. Ongoing monitoring is necessary to assess the long-term impact. Key messages • Mobile health intervention effects may diminish over time. • A non-health-related promotion could stimulate existing mall walking program app users to increase their daily step count temporarily.

Is being a physically active parent related to having a physically active son/daughter?

Abstract Background Engaging in physical activity (PA) during childhood and adolescence can promote lifelong healthy habits and improve overall health. Physically active parents could play a key role in influencing the sons’ and daughters’ PA. The study aimed to evaluate the levels of PA among children and adolescents and to investigate the possible relationship with PA levels of parents. Methods This cross-sectional study involved a random sample of parents of a son/daughter aged 5 to 17 years in the Southern part of Italy. Data were collected through an anonymous self-administered questionnaire designed to retrieve i) sociodemographic characteristics and anthropometric data, ii) parent’s knowledge about the World Health Organization’s (WHO) guidelines (GL) about PA, iii) levels of PA of son/daughter and parent. Results Preliminary findings refer to a sample of 230 parents, of whom, 52.2% were women with a mean age of 38.6 (SD ± 6.8) years. The vast majority of the sample was employed (79.6%) and married (89.1%). Less than half (48.7%) were knowledgeable about WHO’s GLs for PA both in adults (52.6%) and children/adolescents (74.8%). Almost two-thirds (63%) of parents practised PA according to WHO’s GLs. Among sons/daughters, 44.4% practised PA according to WHO’s GLs. The results of the multivariate analysis showed that sons/daughters of physically active parents had higher odds of practising PA according to WHO’s GLs (OR:6.48, 95%CI:3.29-12.79). Similarly, those with parents knowledgeable about WHO’s GLs for PA (OR:3.19, 95%CI:1.75-5.83) were more likely to practise PA according to WHO’s GLs. Conclusions Preliminary results reveal a lack of compliance with WHO’s GL on PA, especially among children and adolescents. This is of concern since it is linked to negative health outcomes in the future. The figure that sons/daughters of active parents had a higher likelihood of being active highlights that public health organizations should prioritise family-based interventions for PA. Key messages • Almost one-third of adults and more than half of the children and adolescents in the sample did not comply with WHO’s recommendations for physical activity. • Sons and daughters of physically active parents are more likely to be active, prompting the need for family-based public health intervention to promote physical activity.

Evaluating the feasibility of an Adapted Physical Activity intervention among breast cancer patients

Abstract Adapted physical activity (PA) programs have shown promising results to reduce physical, psychological and social side effects associated with breast cancer (BC), but the extent to which they can be effectively adopted, implemented and maintained is unclear. The aim of this study is to use the RE-AIM (Reach, Effectiveness, Adoption, Implementation and Maintenance) framework to evaluate RIPOSTE (Reconstruction, Image de soi, Posture, Oncologie, Santé, Thérapie, Escrime), an innovative intervention focused on improving the quality of life (QoL) of BC surgery patients through fencing. A convergent mixed-methods pilot study was conducted to evaluate the RE-AIM dimensions of RIPOSTE. 24 participants who have just undergone surgery for invasive BC were randomly allocated either in the “RIPOSTE” group (starting immediately after their inclusion), or the “Delayed RIPOSTE” group (starting at 3 months following their inclusion). They answered to questionnaires at inclusion and at the end of the program on QoL, shoulder functional capacity, fatigue, anxiety-depression and PA. Interviews were conducted with 10 participants, 3 sports physicians and 1 fencing master. RIPOSTE program was able to reach mainly young and dynamic participants, attracted by the originality of fencing and keen to improve their physical condition. Regarding effectiveness, our results suggest a trend to the improvement of health indicators, even without any significant differences between the two groups. The cooperation, exchanges and cohesion within the group greatly facilitated the adoption of the program, whereas interruptions during vacations were the main barriers. Maintenance analyses showed that most participants continued to practice PA after the program. RIPOSTE is an acceptable and effective program for involving BC survivors in PA, that needs to be tested at larger scale to investigate its effectiveness, but has the potential to be transferred and scaled up worldwide. Key messages • These results would help to enrich the literature on how to best intervene to enhance treatment and recovery among patients and facilitate transfer from a research program to a field daily practice. • By highlighting complexities of RIPOSTE effectiveness and implementation, this study could lead to a more complete program that addresses issues related to improving external and internal validity.

Trajectories of physical activity among participants of six-month mobile app-based disease management program for cardiovascular risk: a group-based trajectory modelling approach

Abstract Background Mobile app-based health promotion is an emerging preventive intervention for cardiovascular disease that allows for the frequent and longitudinal monitoring of physical activity (PA). Previous studies exploring PA trajectories categorized participants in a limited number of follow-up assessments and did not consider dynamic nature with changes that occur over the intervention period. Purpose This study explored the trajectories of PA during mobile app-based disease management programs in adults with cardiovascular risk using group-based trajectory modelling (GBTM). Methods Participants who completed a six-month disease management program using a mobile app were enrolled. The program promoted behavioural changes for the management of cardiovascular risk factors in individuals with one or more of hypertension, diabetes, or dyslipidaemia. Daily step count was measured using a wrist-worn activity tracker (Fitbit devices). Each participant was encouraged to wear a tracker for the monitoring of exercise and physical activity. To analyse relatively physically inactive participants, we included those with baseline step count &amp;lt;8,000 steps/day. GBTM was conducted to identify distinct patterns of longitudinal step count changes of baseline, 3-22 weeks, and 24 weeks. Participants with PA measurements &amp;lt;4 time points were excluded. The baseline characteristics and indicators related to mobile app usage during the first two weeks were compared among the trajectory groups. Results A total of 1,760 participants were included in the analysis (age: median 55 years; 83.8% men; body mass index (BMI): median 27.0 kg/m²; baseline step count: median 6,118 steps/day). GBTM identified four step count trajectory groups: rapid increase (T1, rapid increase in the first three months; 5%), gradual increase (T2, gradual increase in the first three months; 24%), moderate activity (T3, maintained at around 7,000 steps/day; 45%), and physically inactive (T4, around 4,500 steps/day throughout the program; 26%) (Figure 1). The trajectory groups that showed increasing PA patterns were older (T1: median 57 years; T2: 55 years; T3: 55 years; T4: 54 years; p=0.040) with a lower baseline BMI (T1: median 26.6 kg/m²; T2: 26.4 kg/m²; T3: 27.0 kg/m²; T4: 27.7 kg/m²; p&amp;lt;0.001) and were predominantly men (T1: 89.5%; T2: 87.4%; T3: 82.8%; T4: 81.1%; p=0.028). PA increasing patterns were associated with a longer time of mobile app use (T1: median 8.5 min/day; T2: 5.5 min/day; T3: 5.5 min/day; T4: 4.9 min/day; p=0.012) and more login times (T1: median of daily average 3.9/day; T2: 3.0/day; T3: 3.1/day; T4: 2.9/day; p=0.003) during the first two weeks of the program. Conclusions GBTM showed that 30% of participants in the mobile app-based intervention showed significant PA improvement during the first 12 weeks. Results of this study suggest that the response to PA intervention may be associated with lifestyle prior to the program and willingness to use the mobile app.Figure 1.Step count trajectories

Population-based physical activity promotion with a focus on health equity: evidence challenges

Abstract Issue Physical activity (PA) approaches that target the entire population hold great promise for public health particularly in terms of health equity due to their broad reach. During the process of developing national recommendations for PA and PA promotion in Germany, followed by a partial update, it became evident that there is limited evidence regarding population-based PA interventions with a focus on health equity. Our objective was to present an overview of the underlying reasons for this scarcity of evidence. Methods The methodology used in the development of the German recommendations to identify evidence for population-based health equity interventions was applied. Five scientific databases were searched for reviews published between 2015-2021. References of the included reviews were checked for additional reviews. Publications without any focus on health equity were not considered. The identified evidence was summarized narratively, followed by a description of existing challenges in evaluating. Results Our search yielded 4,411 reviews, of which 79 met the inclusion criteria but 75 were excluded because approaches did not focus on the whole population, or did not address health equity. Two reviews were found in the search for gray literature. Thus, the result is a total of 6 articles. None of these reviews reported the application of a theory. The consideration of quality criteria used before, during and after the practical implementation of interventions is not common. The complexity of population-based approaches proved to be a challenge. Conclusions Overall, there is a need for more emphasis on health equity in the implementation and evaluation of population-based PA approaches. The consideration of a theoretical underpinning of such complex approaches in complex systems and the application of standardised quality criteria are an important prerequisite for the generation of evidence. Key messages • There is little evidence of population-based PA approaches aimed at health equity. • A standardized and comprehensive evaluation assessment that is accepted by all public health stakeholders is needed.

Digital, Social Micro-Interventions to Promote Physical Activity Among Midlife Adults With Elevated Cardiovascular Risk: An Ambulatory Feasibility Study With Momentary Randomization.

Although regular physical activity (PA) mitigates the risk for cardiovascular disease (CVD) during midlife, existing PA interventions are minimally effective. Harnessing social influences in daily life shows promise: digital micro-interventions could effectively engage these influences on PA and require testing. This feasibility study employed ecological momentary assessment with embedded micro-randomization to activate two types of social influences (i.e., comparison, support; NCT04711512). Midlife adults (N = 30, MAge = 51, MBMI = 31.5kg/m2, 43% racial/ethnic minority) with ≥1 CVD risk conditions completed four mobile surveys per day for 7 days while wearing PA monitors. After 3 days of observation, participants were randomized at each survey to receive 1 of 3 comparison micro-interventions (days 4-5) or 1 of 3 support micro-interventions (days 6-7). Outcomes were indicators of feasibility (e.g., completion rate), acceptability (e.g., narrative feedback), and potential micro-intervention effects (on motivation and steps within-person). Feasibility and acceptability targets were met (e.g., 93% completion); ratings of micro-intervention helpfulness varied by intervention type and predicted PA motivation and behavior within-person (srs=0.16, 0.27). Participants liked the approach and were open to ongoing micro-intervention exposure. Within-person, PA motivation and behavior increased from baseline in response to specific micro-interventions (srs=0.23, 0.13), though responses were variable. Experimental manipulation of social influences in daily life is feasible and acceptable to midlife adults and shows potential effects on PA motivation and behavior. Findings support larger-scale testing of this approach to inform a digital, socially focused PA intervention for midlife adults.

Investigating the Feasibility and Acceptability of a Facebook Delivered, Parent Mediated, Physical Activity Intervention for Children with Developmental Coordination Disorder

ABSTRACT Objective Children with Developmental Coordination Disorder (DCD) experience difficulties performing fundamental movement skills, resulting in reduced physical activity (PA). Given low PA can impact mental and physical health, improving PA in DCD appears imperative. This study investigates the feasibility of a Facebook delivered, parent mediated, PA intervention for children with DCD. Methods Parents of children with DCD (n=31; 5-11 years), were invited to private Facebook groups where physical activity resources and questionnaires were provided over 12 weeks. Parents and their children wore activity trackers during the intervention period. Feasibility and acceptability of the intervention was considered with reference to (1) Facebook engagement, (2) adherence intervention components, and (3) parent perspectives. Results Facebook engagement was high, with 78.03% (SD=23.06) of all intervention posts being viewed by parents on average. Activity trackers were worn correctly for 92.45% of intervention days and 95.61% of intervention weeks. Weekly questionnaires were completed, on average, 84.37% of the time. Parent perspectives were positive, with 80.77% somewhat or strongly agreeing that the intervention was useful for themselves and their child. Conclusions Given the results described, Facebook appears to be a feasible platform through which parent mediated physical activity interventions can be provided to children with DCD.
