Brief Summary

This study assessed a 12-week, family-oriented program intended to promote healthier 24-hour movement patterns among school-age children and their parents in Chile. Parent-child pairs volunteered from two private schools and one public school, and schools were used to determine group assignment in a parallel, non-randomized, open-label design. The intervention blended brief weekly digital guidance for parents (concise infographics/videos and actionable tips sent via email/WhatsApp) with three in-person family sessions (a functional-training class, parent-child modified games, and an outdoor trekking activity) led by a Physical Education teacher with support from school staff. The comparison group continued usual routines and completed the same assessments. Outcomes were collected at baseline and after the intervention period (post-intervention window around Week 16). The primary outcome was the change in children's out-of-school moderate-to-vigorous physical activity (MVPA) estimated with the Youth Activity Profile-Spain/Latin America version (YAP-SL). Secondary outcomes encompassed children's in-school and weekend MVPA, sedentary time, and sleep duration, as well as parents' MVPA and sedentary time (IPAQ-Short Form) and perceived physical fitness for both parents and children (International Fitness Scale, IFIS). Potential intervention-related adverse events during face-to-face activities and those reported between sessions were monitored. The institutional ethics committee approved the protocol and the intervention was considered minimal risk. This is a retrospective registration completed after study execution at the request of the sponsor. An exploratory mediation analysis is planned to examine plausible pathways linking the program to changes in MVPA.

Outcome Measures

Primary Outcomes (1)

  • Change in children's out-of-school moderate-to-vigorous physical activity (MVPA), min/day

    Daily minutes of MVPA estimated from the Youth Activity Profile-Spain/Latin America version (YAP-SL), using its established calibration procedure to convert item responses into minutes/day; higher values indicate more MVPA.

    Baseline (Weeks 1-3) and Post-intervention (~Week 16)

Secondary Outcomes (8)

  • Change in children's in-school MVPA, min/day

    Baseline (Weeks 1-3) and Post-intervention (~Week 16)

  • Change in children's weekend MVPA, min/day

    (Weeks 1-3) and Post-intervention (~Week 16)

  • Change in children's sedentary time, hours/day

    Baseline (Weeks 1-3) and Post-intervention (~Week 16)

  • Change in children's sleep duration, hours/day

    Baseline (Weeks 1-3) and Post-intervention (~Week 16)

  • Change in parents' MVPA, min/week

    Baseline (Weeks 1-3) and Post-intervention (~Week 16)

  • +3 more secondary outcomes

Study Arms (2)

Experimental: Family-Based Multicomponent Program

EXPERIMENTAL

12-week family-based program combining weekly parent digital guidance (infographics/videos + actionable tips) and three 90-min family sessions (functional training, modified games, outdoor trekking) led by a Physical Education teacher.

Behavioral: Family-Based 12-Week Multicomponent Program

No Intervention: Usual Activities

NO INTERVENTION

Participants continue usual routines; same assessment schedule as the experimental arm.

Interventions

Weekly digital materials to parents (email/WhatsApp) + three on-site sessions (\~90 min each: functional training; modified games; outdoor trekking); 12 weeks total; delivered by a Physical Education teacher; attendance and delivery logs for fidelity.

Also known as: Family Physical Activity Program
Experimental: Family-Based Multicomponent Program

Eligibility Criteria

Age8 Years+
Sexall

Intervention Model
PARALLEL
Model Details: Non-randomized, two-arm, parallel study conducted in Chilean primary schools. Parent-child dyads were assigned by school-level scheduling/feasibility to either the multicomponent family-based program or usual activities. The intervention combined weekly digital guidance for parents and three family in-person sessions led by a Physical Education teacher. Outcomes were assessed at baseline and post-intervention (\~Week 16). Analyses compare change scores between groups, adjusting for baseline and design features appropriate to non-randomized allocation.

Requests must be consistent with consent and ethics approvals.

Shared Documents
STUDY PROTOCOL, SAP
Time Frame
Beginning 6 months after the Primary Completion Date and available for 36 months thereafter (extensions considered upon reasonable request).
Access Criteria
Available to qualified researchers with IRB/ethics approval and a signed Data Use Agreement. Requests should include a brief proposal and analysis plan and be sent to the Principal Investigator.
