Alarming low adherence to the 24-Hour Movement Behavior in adolescents - the Cogni-Action Project

Area of Science:

• Public Health
• Adolescent Health
• Behavioral Science

Background:

• Unhealthy movement behaviors are a significant global concern, especially in developing regions.
• Adolescent adherence to 24-Hour Movement Behavior (24-HMB) guidelines requires evaluation using objective and self-reported measures.
• Understanding the interplay of moderate-to-vigorous physical activity (MVPA), sleep duration (SD), and sedentary time (ST) is crucial.

Purpose of the Study:

• To assess 24-HMB adherence in Chilean adolescents aged 10-14 years.
• To explore variations in 24-HMB adherence by age and sex.
• To identify the prevalence of meeting recommendations for MVPA, SD, and ST.

Main Methods:

• A cross-sectional study involving 359 Chilean adolescents (53.48% girls).
• Objective measurement of MVPA and SD using accelerometers.
• Self-reported assessment of ST.

Main Results:

• Low adherence rates were observed: 0.84% for MVPA, 4.74% for SD, and 70.47% for ST.
• Very few participants met combined guidelines: 0.56% for ST and MVPA, 3.90% for ST and SD.
• No participants met both SD and MVPA guidelines, or all three 24-HMB guidelines. No significant age or sex differences were found.

Conclusions:

• Findings reveal alarmingly low adherence to 24-HMB among Chilean adolescents.
• Urgent need for targeted public health interventions promoting healthy movement behaviors.
• Advocates for an integrated policy approach addressing MVPA, SD, and ST collectively.
