Learning Objective 1: applied theory based nursing intervention into the promotion of physical activity among adolescents with asthma

Learning Objective 2: understand the importance of continuous physical activity programs for adolescent with asthma in order to maintain normal growth and development.

Background & Purpose: The quality care for asthma must include the normal physical activity for adolescent’s normal development. Regular physical activity not only has benefits for healthy adolescent, but also for adolescent with asthma. The purposes of this study were to compare the stage of change and levels of physical activity between the experimental group and comparison group among adolescent with asthma, as well as within pre-education and post-education.
Method: Participants were comprised of 284 adolescent from one junior high school of Taichung city in Taiwan. 190 of the 284 adolescent participated in a stage-matched physical activity program and the remaining 94 constituted the comparison group.    A structured questionnaire for this study included the intention of physical activity, the physical activity level measurement and the determinants of physical activity was used as the instrument to measure physical activity by self report. The means of physical activity of adolescent before and after the education were reported. Repeat measures and mixed model were used to analyze asthma-related quality of life.
Results: There were significant improvements in the amount of physical activity (moderate-to-vigorous physical activity; MVPA, p<0.0001 and vigorous physical activity; VPA, p<0.0001) and no difference in quality of life between the two groups. However, the one year follow-up is not significant better than pre-test in MVPA and VPA. After the education program, adolescent in the experimental group had significant improvement in the dimensions quality of life in physical disturbances from signs/symptoms, limitations of physical activity and total asthma related quality of life (ARQOL).
Conclusion: Our data show that the education program can improve the physical activity in 6 month. The appropriate series health education program in promoting the adolescent’s physical activity with asthma is necessary
