How Czech Adolescents Perceive Their Physical Activity

Area of Science:

• Adolescent Health
• Behavioral Science
• Public Health

Background:

• Adolescence is a crucial period for establishing physical activity (PA) habits.
• Perceptions of peers' PA influence adolescents' motivation and engagement in PA.
• Understanding adolescents' perceptions of PA norms is vital for public health interventions.

Purpose of the Study:

• To investigate whether Czech adolescents misperceive their peers' physical activity (PA) levels.
• To analyze discrepancies between self-reported PA and perceived descriptive norms of peers' PA.
• To identify factors influencing the underestimation of PA among adolescents.

Main Methods:

• Cross-sectional study of 1289 Czech adolescents aged 11-15 years.
• Physical activity (PA) measured using self-reported HBSC study items.
• Statistical analyses included T-tests, ANOVA, Mann-Whitney U, Kruskal-Wallis H, and binomial regression models.

Main Results:

• Adolescents significantly underestimate the prevalence of sufficient physical activity (PA) among their peers.
• Perceived descriptive norms for PA were reported as worse than adolescents' own PA levels.
• Gender, school grade, and school influenced PA underestimation.

Conclusions:

• A notable gap exists between adolescents' self-perceived PA and their perception of peer PA norms.
• Targeted social-norms-based interventions can potentially increase adolescent PA engagement.
• Addressing misperceptions of PA is a promising strategy to enhance adolescent physical activity levels.
