Overview

This collaborative project aimed to initiate and evaluate the effects of a school-based physical activity program on physical fitness and mental health status of adolescents living in a low socioeconomic status area in Santiago, Chile. The study included 198 students aged 15 years old. Teachers and students designed the intervention program and decided on the best way to implement it. They developed a survey to assess students’ preferences for the activities to be included, and students decided that four units of different sports for 30 sessions each would be tested. Three sessions were held each week and each lasted 90 min. Methods: quasi-experimental design- other. Results: Significant differences were found between the intervention and control groups in maximum oxygen capacity (8.5% in the intervention versus 1.8% in the control group – p 0.01); anxiety score (decreased 13.7% in the intervention group versus 2.8% in the control group – p < 0.01), and self-esteem score (increased 2.3% in the intervention group and decreased 0.1% in the control – p 80%. Implications: These results show that a collaboratively developed school-based program to improve physical activity in adolescents of low socioeconomic status can obtain a high level of participation and achieve significant benefits in terms of physical fitness and mental health status.

      Level of ImpactDescription of OutcomeEquity Focus
      Individual LevelMental health status indicator-Anxiety: A statistically significant improvement of 13.7% in the anxiety score was observed in the group that participated in the program compared with a reduction of 2.8% in the control group (p < 0.0001).Outcomes are reported for people living in conditions of disadvantage, and are not compared to people living in more advantaged conditions.
      Individual LevelMaximum oxygen capacity: Significant differences were found between the intervention and control groups (8.5% in the intervention versus 1.8% in the control group – p 0.01) after the end of the program.Outcomes are reported for people living in conditions of disadvantage, and are not compared to people living in more advantaged conditions.
      Individual LevelSpeed & jump performance: Increased by 10.3% and 9.8% respectively in the intervention group, and by 6.9% and 2.4% in the group that received the standard intervention (p < 0.01)Outcomes are reported for people living in conditions of disadvantage, and are not compared to people living in more advantaged conditions.
      Individual LevelMental health status indicator- Self-esteem: The self-esteem score increased by 2.3% in the intervention group, but decreased by 0.1% in the control group (p 0.001).Outcomes are reported for people living in conditions of disadvantage, and are not compared to people living in more advantaged conditions.

      Adaptability

      Implementation History

      • Implemented once (could be a pilot) - The intervention has been implemented once and is theoretically replicable elsewhere.

      Expertise Required for Implementation within the Context of the Intervention

      • Requires specialized skills that are easily available within the context - The intervention requires the participation of personnel with advanced skills (e.g. medical doctors, epidemiologists, social workers) but that are easily available within the intervention context.

      Are there supports available for implementation

      No.

      Are there resources and/or products associated with the interventions

      Yes. The Tennessee Self-Concept Scale: a validated instrument which is used to measure self-esteem among Chilean adolescents from low socioeconomic status backgrounds.
