A Cocreated Intergenerational Intervention to Promote Co-Physical Activity in Grandparents and Their Grandchildren: "Ages Get Active"-Development, Insights, and Future Directions.

Intergenerational physical activity programs hold promise for increasing (co-)physical activity in children and older adults. Many programs, however, lack effectiveness, potentially due to insufficient evidence-based development and limited addressing of both groups' needs, which could result in a lack of fit. Co-creation and tailored approaches could improve program fit and effectiveness.

Identifying Optimal Moments for Delivering Digital Prompts to Reduce Prolonged Sedentary Behavior in Older Adults: An Intensive Longitudinal Study Using Sensor-Triggered Ecological Momentary Assessment.

Background: The optimal moment to deliver digital prompts for reducing sedentary behavior (SB) is when individuals are susceptible to prolonged SB (vulnerability) and open to behavior change (opportunity). This study aims to examine both vulnerability and opportunity.

Methods: A 14-day ecological momentary assessment study was conducted with 105 older adults.

Adolescent Engagement With a Multicomponent mHealth Tool: Identifying Usage Patterns, Determinants, and Health Behavior Change in an Intervention Trial.

Background: Research about the engagement of adolescents with mobile health (mHealth) interventions is scarce, while it is generally assumed that the engagement affects the intervention efficacy.

Objective: Using an mHealth intervention that targets the general population of adolescents to promote healthy behaviors (physical activity, low sedentary time, adequate sleep, and taking breakfast) and mental health, we aimed to investigate (1) how adolescents engage with the intervention, (2) which engagement styles can be identified and how these differ according to personal characteristics, and (3) which style of engagement predicts behavior change. The intervention used, #LIFEGOALS, includes self-regulation techniques, a support chatbot, narrative videos, and gamification, brought together in an app coupled to an activity tracker.

Understanding for whom, under which circumstances and how sedentary behaviour interventions for older adults work: a realist review.

Objectives: Reducing sedentary behaviour (SB) in older adults is a promising strategy to promote healthy ageing. However, to develop more effective interventions, more in-depth information is needed on how existing interventions work. The present realist review aims to identify the working mechanisms and contextual preconditions to guide the development of future interventions.

Teachers' experiences in co-creating an implementation plan for a public health intervention: a Health CASCADE study.

Modifiable determinants of older adults' physical activity and sedentary behavior in community and healthcare settings: a DE-PASS systematic review and meta-analysis.

Objectives: To identify the modifiable determinants targeted in interventions involving older adults, and to determine which of these interventions effectively increased physical activity (PA) and/or reduced sedentary behaviour (SB). Additionally, to explore whether the effects of these interventions vary based on the implementation setting.

Methods: A search of randomized controlled trials (RCTs) and controlled trials (CTs) was performed in Medline, APA PsycArticles, SPORTDiscus, and Web of Science.

The influence of individual-level determinants on compliance with mHealth walking suggestions and older adults' experiences: A longitudinal exploratory mixed methods study.

Promoting healthy aging through physical activity (PA) is crucial as the global population grows older. Traditional interventions often fail to engage older adults, underlining the need for personalized, timely approaches. Smartphone-delivered PA interventions can offer personalized support during opportune moments for behavioral change.

School staff experiences on involvement in a co-creation process: a Health CASCADE scoping review and thematic synthesis.

Background: Implementing public health interventions in schools requires active involvement of multiple stakeholders and adaptation of interventions to fit local contexts, to account for successful design, implementation, and consequently effectiveness of these interventions. Active collaboration, preferably in a co-creation process, with school staff is needed to enhance the implementation of school-based public health interventions. However, involving them in research through a co-creation process is challenging due to competing demands on their time.
