Design and methods of the StepByStep randomized trial of a mobile health and social media physical activity intervention among adolescent and young adult survivors of childhood cancer: A report from the Children's Oncology Group

BackgroundInterventions to increase physical activity are needed in adolescent and young adult survivors of childhood cancer who are largely inactive but at lifelong elevated risk of multiple chronic conditions improved by physical activity. The goals of the StepByStep study are to evaluate the effects of a 48-week distance-based, multi-component mobile health and social media behavioral intervention on physical activity, biomarkers of cardiometabolic health, and health-related quality of life. MethodsThis ongoing study is a two-arm, prospective, multi-site randomized controlled trial. 384 childhood cancer survivors age ≥ 15 years and < 21 years who were 3–36 months off therapy and not meeting physical activity guidelines were enrolled. The trial will test the efficacy of a 24-week intensive multi-component physical activity intervention combining a wearable physical activity tracker, social media peer support group, and individualized goal setting followed by a 24-week maintenance phase of the intervention to improve outcomes. The control group receives the wearable physical activity tracker only. ConclusionThere is a growing need for novel, developmentally appropriate interventions to increase physical activity and improve the health trajectory of adolescent and young adult survivors of childhood cancer. If efficacious, this portable and scalable intervention would be a much-needed tool to reduce the morbidity from cancer treatment and improve quality of life among survivors after treatment ends.

Assessing the Acceptability of a Preschool-Based Multi-Component Physical Activity Intervention Entitled "I'm an Active Hero" (IAAH): Process Evaluation of a Feasibility Trial.

Interventions within preschool settings have gained prominence due to the need to increase physical activity (PA) in early childhood. We first developed a 10-week preschool-based behaviour change intervention, guided by the UK Medical Research Council's framework for complex interventions. We then conducted a cluster feasibility randomised controlled trial (RCT) among young children. This process evaluation was embedded within the cluster feasibility RCT and aimed to assess the acceptability of the 10-week IAAH intervention among both preschool staff and parents. The study utilised a mixed method, involving post-intervention questionnaires completed by preschool staff (n = 4) and children's parents/caregivers (n = 9) and focus groups with preschool staff (n = 3) and parents/caregivers (n = 7). Quantitative data were analysed using SPSS to calculate acceptability scores, while qualitative data underwent thematic analysis using NVivo 12. The intervention was well-received, with preschool staff reporting a 94.5% acceptability rate (mean score of 10.4 out of 11) and parents/caregivers indicating an 86% acceptance rate (mean score of 5.2 out of 6). Thematic analysis of focus group discussions revealed facilitators to intervention delivery, such as user-friendly materials and alignment with preschool curricula, and identified barriers, including time constraints, spatial limitations, and policy conflicts. Parental engagement was hindered by time restrictions, although the intervention materials were praised for their clarity and visual appeal. The findings suggest that the IAAH programme was acceptable to both preschool staff and parents. However, the identified barriers to intervention delivery and engagement should be addressed in the planning of a future cluster RCT to evaluate the efficacy of the intervention.

Effects of a staff-led multicomponent physical activity intervention on preschooler's fundamental motor skills and physical fitness: The ACTNOW cluster-randomized controlled trial

BackgroundFundamental motor skills (FMS) and physical fitness (FIT) play important roles in child development and provide a foundation for lifelong participation in physical activity (PA). Unfortunately, many children have suboptimal levels of PA, FMS, and FIT. The Active Learning Norwegian Preschool(er)s (ACTNOW) study investigated the effects of a staff-led PA intervention on FMS, FIT, and PA in 3–5-year-old children.MethodsPreschools in Western Norway having ≥ six 3–4-year-old children were invited (n = 56). Of these, 46 agreed to participate and were cluster-randomized into an intervention (n = 23 preschools [381 children, 3.8 yrs., 55% boys]) or a control group (n = 23 [438, 3.7 yrs., 52% boys]). Intervention preschools participated in an 18-month PA intervention involving a 7-month staff professional development between 2019 and 2022, amounting to 50 h, including face-to-face seminars, webinars, and digital lectures. Primary outcomes in ACTNOW were cognition variables, whereas this study investigated effects on secondary outcomes. FMS was measured through 9 items covering locomotor, object control, and balance skills. FIT was assessed as motor fitness (4 × 10 shuttle-run test) and upper and lower muscular strength (handgrip and standing long jump). PA was measured with accelerometers (ActiGraph GT3X +). All measures took place at baseline, 7-, and 18-month follow-up. Effects were analysed using a repeated measures linear mixed model with child and preschool as random effects and with adjustment for baseline scores.ResultsParticipants in the intervention preschools showed positive, significant effects for object control skills at 7 months (standardized effect size (ES) = 0.17) and locomotor skills at 18 months (ES = 0.21) relative to controls. A negative effect was found for handgrip strength (ES = -0.16) at 7 months. No effects were found for balance skills, standing long jump, or motor fitness. During preschool hours, sedentary time decreased (ES = -0.18), and light (ES = 0.14) and moderate-to-vigorous PA (ES = 0.16) increased at 7 months, whereas light PA decreased at 18 months (ES = -0.15), for intervention vs control. No effects were found for other intensities or full day PA.ConclusionsThe ACTNOW intervention improved some FMS outcomes and increased PA short-term. Further research is needed to investigate how to improve effectiveness of staff-led PA interventions and achieve sustainable improvements in children’s PA, FMS, and FIT.Trial registrationClinicaltrials.gov, identifier NCT04048967, registered August 7, 2019.FundingACTNOW was supported by the Research Council of Norway (grant number 287903), the County Governor of Sogn og Fjordane, the Sparebanken Sogn og Fjordane Foundation, and the Western Norway University of Applied Sciences.

Impact of a Multi-Component Physical Activity Intervention on Psychological Well-Being in Older Adults: A Pilot Study

While the positive effects of physical activity (PA) on mental health are well documented, limited research has explored its influence on the positive psychological well-being in elderly individuals. This study examined the effects of a multi-component PA intervention on various facets of psychological well-being among older adults residing in retirement homes. Fifty-eight elderly individuals (mean age = 83.8 years, 76.3% female) residing in retirement homes participated either in either a 12 week multi-component PA intervention program or in an attention control group. Those in the intervention group engaged in supervised group exercise lessons for 45 min, three times per week, and used wearable activity monitors during weekdays over 12 weeks. Assessments were conducted before and after the intervention to measure happiness, life satisfaction, eudaimonic well-being, and depressive symptoms, which are four components of psychological well-being. On average, those in the intervention group attended about 86.9% of group exercise sessions and used the activity trackers for 97.5% of the designated days. Results from linear mixed models indicated that the intervention had a positive effect on happiness in the intervention group, but not in the control group. Nonetheless, no significant differences were found in terms of changes in eudaimonic well-being, life satisfaction, and depressive symptoms between the two groups. This selective impact on different dimensions of psychological well-being implies that subsequent research could explore the integration of more comprehensive components in PA interventions targeting all dimensions of psychological well-being, as each of them is a key aspect of healthy aging and independently related to a range of health outcomes amongst older adults.

A SCOPING REVIEW OF SYSTEMS-LEVEL INTERVENTIONS FOR FALL PREVENTION IN LONG-TERM CARE

Abstract Older adults residing in long-term care facilities (LTCFs) are at high risk for falls. In addition to individual resident-level interventions to prevent falls and fall-related injury (FRI), system-focused interventions are also necessary to adequately address fall prevention. Relatively little attention has been given to research involving systems-focused interventions. We aimed to synthesize studies on the effects of system-focused interventions for fall and FRI prevention in LTCFs with the goal of identifying promising strategies and gaps. We searched Medline, CINAHL, and EMBASE databases from 2017 to 2022 following the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guideline. We conducted a narrative synthesis to summarize included studies. In the initial review, 301 studies were identified and underwent title and abstract screening resulting in 98 articles were retrieved for full-text review. Fifteen studies were included in data extraction. Fall prevention interventions evaluated in LTCF settings include: (1) multicomponent fall prevention programs, (2) staff education programs, (3) training in safe handling/transfers, (4) environmental adaptations, (5) electronic health record algorithms and prompts, (6) local culture change, (7) video analysis of falls to change local interventions, and (8) facility-level physical activity programs. About half of reported studies reported significant effects of system-focused interventions to reduce fall and FRI in LTCFs. Multicomponent fall prevention programs and physical activity interventions are the most effective systems-level interventions, while electronic health record interventions were the least effective. Overall, little attention has been given in the literature to evaluation of environmental adaptations at the systems level.

A multicomponent physical activity home-based intervention for fibromyalgia patients: effects on clinical and skin biopsy features.

Adapted physical activity (APA) has been recommended for fibromyalgia (FM) treatment as an essential component of a biopsychosocial therapeutic approach for patients. Previous studies report that aerobic and resistance training are the most effective programs in improving the quality of life and psycho-physical well-being. Patients with FM are frequently affected by an impairment of small fibers innervation, which is evident in the proximal somatic districts. Therefore, this pilot randomised controlled not pharmacological trial aimed to investigate if a 12-week home-based multicomponent (aerobic and resistance training and mobility) physical activity (PA) intervention was effective in improving pain perception, FM-related disability, and IntraEpidermal Nerve Fibers Density (IENFD) in adult FM patients. Thirty-four female subjects with a fibromyalgia diagnosis (51.5±11.88 years) were randomly assigned to an experimental group (n=17) that received a supervised home-based multicomponent PA intervention twice a week and a control group (n=17) that received a generic program of aerobic exercise. Skin biopsy was performed before the physical program and after 18 months with constant execution of the supervised PA intervention or generic aerobic exercise. Both groups assumed pharmacological treatment with duloxetine and/or pregabalin. We found that the group performing physical activity in a supervised and regular way showed a significant improvement in the Fibromyalgia-linked invalidity questionnaire (FIQ) as well as epidermal fibers density at proximal and distal sites. Physical activity could improve FM outcomes, with a possible beneficial impact on peripheral factors contributing to pain-related disability.

A Contactless App-Based Intervention to Improve Health Behaviors in Airline Pilots: A Randomized Trial

There is a need for enhanced preventive health care among airline pilots to mitigate the prevalence of cardiometabolic health risk factors. A randomized, waitlist-controlled trial was utilized to evaluate the effectiveness of a smartphone-based app intervention for improving health behaviors and cardiometabolic health parameters. A total of 186 airline pilots (aged 43.2±9.1 years; male, 64%) were recruited and participated in the trial during 2022. This intervention was a personalized, 16-week smartphone-based app multicomponent physical activity, healthy eating, and sleep hygiene intervention. Outcome measures of objective health (Cooper's 12-minute exercise test, resting heart rate, push ups, plank isometric hold, body mass), subjective health (self-rated health, perceived psychological stress and fatigue), and health behaviors (weekly physical activity, sleep quality and duration, fruit and vegetable intake) were collected at baseline and after intervention. The waitlist control completed the same measures. Significant interactions for time Χ group from baseline to 16 weeks were found for all outcome measures (p<0.001). Significant between-group differences for positive health changes in favor of the intervention group were found after intervention for all outcome measures (p<0.05, d=0.4-1.0) except for self-rated health, body mass, and Pittsburgh Sleep Quality Index score. Study findings show that an app-based health behavior intervention can elicit positive cardiometabolic health changes among airline pilots over 16 weeks, associated with trivial to large effect sizes. The trial protocol was prospectively registered at The Australian New Zealand Clinical Trials Registry (ACTRN12622000288729).

A multi-component, community-based outdoor gym intervention: the ecofit effectiveness trial

Introduction: In Australia, it is estimated that 45% of adults meet the aerobic training recommendations (i.e., 150-300 minutes of MVPA) and only 9-30% meet the resistance training (RT) guidelines (i.e., minimum 2 sessions/week). Given the lack of ‘scalable’ physical activity community-based interventions promoting RT, the aim of this effectiveness trial (based on the published ecofit efficacy trial) was to determine the effects of an innovative community-based multicomponent physical activity intervention promoting resistance and aerobic-based physical activity using outdoor gym equipment, smartphone technology, and social support.

Feasibility and Acceptability of an Active Video Game-Based Physical Activity Support Group (Pink Warrior) for Survivors of Breast Cancer: Randomized Controlled Pilot Trial.

BackgroundSurvivors of breast cancer with functional limitations have a 40% higher mortality rate than those without. Despite the known benefits of physical activity (PA), <40% of survivors of breast cancer meet the recommendations for PA. The combination of active video games (AVGs) and group-based PA counseling may hold potential for motivating PA adoption and improving physical function. However, this method has not been widely studied in survivors of breast cancer.ObjectiveWe aimed to determine the feasibility and acceptability of a group AVG-based multicomponent PA intervention and estimate its effect size and variability on PA and physical function in female survivors of breast cancer in a clinic setting.MethodsFemale survivors of breast cancer (N=60) were recruited through the clinic and randomly assigned to the intervention group (12 weekly sessions) or the control group (existing support group). The intervention group received game-based pedometers and participated in weekly group AVG sessions, PA behavioral coaching, and survivorship navigation discussions. A participant manual with weekly reflection worksheets was provided to reinforce the coaching lessons and promote self-led PA. The control group received conventional pedometers and participated in an existing breast cancer support group. Feasibility was assessed by enrollment rate (≥50%), retention rate (≥80%), group attendance rate (75% attending ≥9 sessions [intervention group]), and the number of technological issues and adverse events. Acceptability was measured by participants’ attitudes (from strongly disagree=1 to strongly agree=5) toward the use of AVGs and the overall program. The outcomes included PA (accelerometers) and physical function (Short Physical Performance Battery and gait speed). Analysis of covariance was used to determine differences in PA and physical function between the groups. The Cohen d and its 95% CI determined the effect size and variability, respectively. All the analyses followed the intention-to-treat principle.ResultsParticipants were an average of 57.4 (SD 10.5) years old, 70% (42/60) White, and 58% (35/60) off treatment. The enrollment rate was 55.9% (66/118). Despite substantial long-term hurricane-related disruptions, we achieved an 80% (48/60) retention. The intervention group’s attendance rate was 78% (14/18), whereas the control group’s attendance rate was 53% (9/17). Of the 26 game-based pedometers, 3 (12%) were damaged or lost. No study-related adverse events occurred. Acceptability items were highly rated. Steps (β=1621.64; P=.01; d=0.72), Short Physical Performance Battery (β=.47; P=.01; d=0.25), and gait speed (β=.12; P=.004; d=0.48) had a significant intervention effect.ConclusionsThe intervention was feasible and acceptable in this population despite the occurrence of a natural disaster. Pilot results indicate that group AVG sessions, PA coaching, and survivorship navigation produced moderate effects on PA and physical functioning. AVGs with PA counseling can potentially be used in existing breast cancer support groups to encourage PA and improve physical function.Trial RegistrationClinicalTrials.gov NCT02750241; https://clinicaltrials.gov/ct2/show/NCT02750241

Women's Health Initiative Strong and Healthy (WHISH): A pragmatic physical activity intervention trial for cardiovascular disease prevention

BackgroundNational guidelines promote physical activity to reduce cardiovascular disease (CVD); yet, no RCT has tested the effectiveness of physical activity as the sole intervention for primary CVD prevention in older adults. The Women's Health Initiative (WHI) Strong and Healthy (WHISH) trial, a pragmatic trial embedded in the WHI-Extension Study (ES), is testing whether increasing physical activity and decreasing sedentary behavior will reduce major CV events in older women. MethodsThe randomized consent design was used to assign 49,331 women (aged 68–99 years in 2015) who had consented to ongoing WHI-ES follow-up and for whom CV outcomes were available through WHI-ES procedures (N = 18,985) and/or linkage to the Centers for Medicare and Medicaid Services (N = 30,346) to a physical activity (PA) intervention designed to promote national recommendations (N = 24,657) or “usual activity” comparison (N = 24,674). Women assigned to the intervention provided passive consent to receive the intervention and provide data. A multi-component PA intervention is delivered by seasonal (quarterly) newsletters with targeted inserts (lower, middle, higher) based on self-reported levels of physical functioning (PF) and physical activity; monthly motivational telephone messages; monthly emails; a website; and contact with staff, as requested. Major CV events, myocardial infarction (MI), stroke, or CVD death, collected annually through WHI-ES, comprise the primary outcome. Hip fracture and non-CVD death are primary safety outcomes. Intention-to-treat analyses in all randomized participants will include 8 years of follow-up. ConclusionDetermining whether increased physical activity and decreased sedentary behavior reduce major CV events in older women is of major public health significance.Clinical trials registration:ClinicalTrials.govidentifier:NCT02425345

Examining the sustainability and effectiveness of co-created physical activity interventions in vocational education and training: a multimethod evaluation

BackgroundCo-creation approaches are increasingly used in physical activity promotion to develop interventions tailored to the target group and setting. The resulting complexity of such interventions raises challenges in evaluation. Accordingly, little is known about the effectiveness of co-created interventions and the underlying processes that impact their sustainable implementation. In this study, we attempt to fill this gap by evaluating co-created multi-component physical activity interventions in vocational education and training in nursing care and automotive mechatronics regarding (1) their sustainable implementation at the institutional level and (2) the effectiveness of single intervention components at the individual level.MethodsFollowing a multimethod design, we conducted a questionnaire survey (n = 7) and semi-structured interviews (n = 4) to evaluate the sustainability of the interventions. Quantitative data were analyzed descriptively, and qualitative data were analyzed using qualitative content analysis. To examine the interventions’ effectiveness, we conducted two non-randomized controlled trials (n = 111). Analysis of variance was used to examine differences between groups.ResultsAt the institutional level, long-term implementation of single intervention components in nursing care was observed; in contrast, long-term implementation in automotive mechatronics was not observed. In this context, various factors at the outer contextual (e.g., COVID-19 pandemic), inner contextual (e.g., health-promoting leadership), intervention (e.g., acceptance), and personal levels (e.g., champion) influenced sustainability. At the individual level, no significant intervention effects were found for changes in physical activity behavior and physical activity-related health competence.ConclusionThe role of co-creation on the effectiveness and sustainability of physical activity promotion in vocational education and training cannot be answered conclusively. Only in the nursing care sector, a co-creation approach appeared promising for long-term intervention implementation. Sustainable implementation depends on various influencing factors that should be considered from the outset. Demonstrating effectiveness at the individual level was challenging. To conclusively clarify both the role and impact of co-creation, methodologically complex and elaborate evaluation designs will be required in future research projects.Trial registrationThis study was retrospectively registered at clinicaltrials.gov on 24/08/2021 (NCT05018559).

Working memory interventions via physical activity and ICTs: A strategic issue for the improvement of school students' learning performance

Nowadays, there is a great need for schools to be transformed into more innovative learning environments with more innovative approaches to learning and teaching so as students to be allowed to develop their various skills and abilities to their fullest extent. Therefore, we present the role of physical activity and ICT-based interventions for working memory enhancement as a strategic issue for the improvement of students’ learning outcomes. According to research findings, multi-component exercise and ICT-based intervention programs can significantly contribute to the improvement of children’s and adolescents’ working memory and thus can have a positive effect on children’s and adolescents’ learning performance. Finally, this paper could trigger educators and policy-makers towards the ideal planning of innovative multi-component physical activity and ICT-based intervention programs and their incorporation into the school curriculum aiming at the working memory enhancement in children and adolescents and the improvement of their learning outcomes

Community-based physical activity and/or nutrition interventions to promote mobility in older adults: An umbrella review.

Background: Physical activity and a healthy diet are important in helping to maintain mobility and quality of life with aging. Delivery of physical activity and nutrition interventions in a group setting adds the benefits of social participation. Several published systematic reviews have explored a broad range of PA and/or nutrition interventions for older adults, making it challenging to bring together the best scientific evidence to inform program design and to inform multicomponent intervention development. This umbrella review aims to identify group-based physical activity and nutrition interventions for community-dwelling older adults that improve mobility. Methods: Five electronic databases (MEDLINE, Embase, CINAHL, Cochrane CENTRAL, Sociological Abstracts) were searched from inception to April 28, 2020. Eligibility criteria included systematic reviews exploring the effectiveness of physical activity and/or nutrition interventions, delivered in a group setting for community-dwelling older adults. Two reviewers independently performed eligibility screening, critical appraisal (using AMSTAR 2) and data extraction. The GRADE approach was used to assess the overall certainty of the evidence. Older adult/provider research partners informed data synthesis and results presentation. Results: In total, 54 systematic reviews (1 high, 21 moderate, 32 low/critically low quality) were identified; 46 included physical activity only, and eight included both physical activity and nutritional supplements. No reviews included nutrition interventions alone. Combined aerobic/resistance, general physical activity, and mind-body exercise all improved physical function and balance (moderate-high certainty). Aerobic/resistance training improved aerobic capacity (high certainty). Resistance training and general physical activity improved muscle strength (moderate certainty). Aerobic/resistance training and general physical activity are likely to reduce falls among older adults (moderate certainty). There was no evidence of benefit for nutritional supplementation with physical activity. Conclusions: Multicomponent group-based physical activity interventions can improve measures of mobility in community-dwelling older adults. We found no reviews focused on nutrition only, highlighting a gap in the literature.

ACCEPTANCE: protocol for a feasibility study of a multicomponent physical activity intervention following treatment for cervical cancer

Three-Year Intervention Effects on Food and Beverage Intake-Results from the Quasi-Experimental Copenhagen School Child Intervention Study (CoSCIS).

The diet of Danish children is often not in accordance with dietary guidelines. We aimed to evaluate changes in the intake of selected foods and beverages during a multi-component school-based physical activity intervention, and to investigate if changes were modified by socioeconomic status (SES). The study included 307 children (intervention group: 184; comparison group: 123) with information on dietary intake pre- and post-intervention as well as on SES. Linear regression models were conducted to assess the effect of the intervention on changes in dietary factors. Children from the intervention group increased their intake of whole-grain bread during the intervention (group means: 6.1 g/d (95% CI: 2.2 to 10.0) vs. 0.3 g/d (95% CI: −3.1 to 3.7) in the comparison group, p = 0.04). A significant interaction between SES and group allocation was observed to change in fruit intake (p = 0.01). Among children from low SES families, only those from the comparison group decreased their fruit intake (group means: −40.0 g/d (95% CI: −56.0 to −23.9) vs. 9.3 g/d (95% CI: −16.1 to 94) in the intervention group, p = 0.006). The present study found no convincing effect of introducing a multi-component intervention on dietary intake except a small beneficial effect on whole-grain bread consumption. However, beneficial intervention effects in fruit intake were found particularly among children from low SES families.

Cost-Effectiveness of a School-and Family-Based Childhood Obesity Prevention Programme in China: The "CHIRPY DRAGON" Cluster-Randomised Controlled Trial.

Objectives: Rapid socioeconomic and nutrition transitions in Chinese populations have contributed to the growth in childhood obesity. This study presents a cost-effectiveness analysis of a school- and family-based childhood obesity prevention programme in China.Methods: A trial-based economic evaluation assessed cost-effectiveness at 12 months. Forty schools with 1,641 children were randomised to either receive the multi-component (diet and physical activity) intervention or to continue with usual activities. Both public sector and societal perspectives were adopted. Costs and benefits in the form of quality-adjusted life years (QALYs) were compared and uncertainty was assessed using established UK and US thresholds.Results: The intervention cost was 35.53 Yuan (£7.04/US$10.01) per child from a public sector perspective and 536.95 Yuan (£106/US$151) from a societal perspective. The incremental cost-effectiveness ratio (ICER) was 272.7 Yuan (£54/US$77)/BMI z-score change. The ICER was 8,888 Yuan (£1,760/US$2,502) and 73,831 Yuan (£14,620/US$20,796) per QALY from a public sector and societal perspective, respectively and was cost-effective using UK (£20,000) and US (US$50,000) per QALY thresholds.Conclusion: A multi-component school-based prevention programme is a cost-effective means of preventing childhood obesity in China.

Efficacy of a Multi-Component m-Health Diet, Physical Activity, and Sleep Intervention on Dietary Intake in Adults with Overweight and Obesity: A Randomised Controlled Trial.

This three-arm randomised controlled trial evaluated whether (1) a multi-component weight loss intervention targeting diet, physical activity (PA), and sleep was effective at improving dietary intake over six months and 12 months, compared with a control, and (2) the enhanced diet, PA, and sleep intervention was more effective at improving dietary intake than the traditional diet and PA intervention. A total of 116 adults (70% female, 44.5 years, BMI 31.7 kg/m2) were randomised to either traditional diet and PA intervention; enhanced diet, PA, and sleep intervention; or wait-list control. To examine between-group differences, intervention groups were pooled and compared with the control. Then, the two intervention groups were compared. At six months, the pooled intervention group consumed 1011 fewer kilojoules/day (95% CI −1922, −101), less sodium (−313.2 mg/day; 95% CI −591.3, −35.0), and higher %EI from fruit (+2.1%EI; 95% CI 0.1, 4.1) than the controls. There were no differences in intake between the enhanced and traditional groups at six months. At 12 months, the pooled intervention and control groups reported no significant differences. However, compared to the traditional group, the enhanced reported higher %EI from nutrient-dense foods (+7.4%EI; 95% CI 1.3, 13.5) and protein (+2.4%EI; 95% CI 0.1, 4.6), and reduced %EI from fried/takeaway foods (−3.6%EI; 95% CI −6.5, −0.7), baked sweet products (−2.0%EI; 95% CI −3.6, −0.4), and packaged snacks (−1.1%EI; 95% CI −2.2, −0.3). This weight loss intervention reduced total energy and sodium intakes as well as increased fruit intake in adults at six months. The enhanced intervention group reported improved dietary intake relative to the traditional group at 12 months.

Multi-Component Physical Activity Interventions in the UK Must Consider Determinants of Activity to Increase Effectiveness.

Interventions to increase physical activity in children have adopted broad approaches and achieved varying success. There is a need to adopt approaches underpinned with a theoretical basis. Accordingly, the aim here was to implement and evaluate a 12-week intervention designed using the concepts of the COM-B model to determine the effect this has on physical activity levels. One hundred and forty-seven school-age children (mean age 8.9 ± 1.3 years) took part in a 12-week program delivered in a school setting. Topics included physical activity, healthy eating, sleep quality and reducing screen time/sedentary activities when not in school. A sample of participants wore a wrist-worn accelerometer for seven days pre-and post-intervention (N = 11). The physical activity frequency was unchanged (2.9 ± 1.0 AU) when compared with post-intervention values (3.1 ± 0.8 AU, mean increase 6.8 ± 3.7%, p > 0.05). Changes were observed in the daily consumption of fruit and vegetables (pre-intervention 44.6% vs. post-intervention 60.2%, p < 0.05). Sedentary time, light activity, moderate activity and vigorous activity were unchanged post-intervention (p > 0.05). There is a need to adopt a broader approach that incorporates a theoretical basis and considers the complex ways by which physical activity behaviours are influenced.

Physiotherapy and related management for childhood obesity: A systematic scoping review.

IntroductionDespite targeted efforts globally to address childhood overweight/obesity, it remains poorly understood and challenging to manage. Physiotherapists have the potential to manage children with obesity as they are experts in movement and physical activity. However, their role remains unclear due to a lack of physiotherapy-specific guidelines. This scoping review aims to explore existing literature, critically appraising and synthesising findings to guide physiotherapists in the evidence-based management of childhood overweight/obesity.MethodA scoping review was conducted, including literature up to May 2020. A review protocol exists on Open Science Framework at https://osf.io/fap8g/. Four databases were accessed including PubMed, Embase, CINAHL, Medline via OVID, with grey literature searched through google via “file:pdf”. A descriptive synthesis was undertaken to explore the impact of existing interventions and their efficacy.ResultsFrom the initial capture of 1871 articles, 263 intervention-based articles were included. Interventions included qualitative focused physical activity, quantitative focused physical activity and multicomponent interventions. Various outcome measures were utilised including health-, performance- and behaviour-related outcomes. The general trend for physiotherapy involvement with children who are obese appears to favour: 1) multicomponent interventions, implementing more than one component with environmental modification and parental involvement and 2) quantitative physical activity interventions, focusing on the quantity of bodily movement. These approaches most consistently demonstrated desirable changes across behavioural and health-related outcome measures for multicomponent and quantitative physical activity interventions respectively.ConclusionWhen managing children with obesity, physiotherapists should consider multicomponent approaches and increasing the quantity of physical activity, given consistent improvements in various obesity-related outcomes. Such approaches are well suited to the scope of physiotherapists and their expertise in physical activity prescription for the management of childhood obesity. Future research should examine the effect of motor skill interventions and consider the role of environmental modification/parental involvement as factors contributing to intervention success.

A Systematic Review of Multi-Component Comprehensive School Physical Activity Program (CSPAP) Interventions.

To identify, review, and describe multicomponent physical activity (PA) interventions in terms of: (a) number and combination of Comprehensive School Physical Activity Program (CSPAP) components, (b) study characteristics, and (c) primary outcomes. Five electronic databases (i.e., PubMed, PsychInfo, Physical Education Index, Sport Discus, and ERIC). Included articles were peer-reviewed, written in English language, published since 1987, and included multicomponent school-based interventions. Data items extracted were: school level, setting, CSPAP component description, health outcomes, academic outcomes, main conclusion, and reference. Included articles were synthesized by: (1) CSPAP components utilized, and (2) research outcome measured (i.e., health or academic). Across 32 studies, 11 included physical education plus 1 additional CSPAP component (PE + 1); 10 included PE + 2 additional CSPAP components; 8 included PE + 3 additional CSPAP components; and 1 included all 5 CSPAP components. Two other studies included 2 or 3 CSPAP components without PE. Most interventions targeted health outcomes (94%) rather than academic outcomes (6%). Multicomponent approaches aligned with CSPAPs are effective in promoting PA and other positive outcomes for youth in schools. Future research should seek to understand effects of CSPAP components on a variety of outcomes and settings.
