Abstract

Objectives

To evaluate the impact of a curricular intervention concerning the knowledge about asthma among adolescents from a public school.

Methods

This was a randomized, controlled trial study on a curricular intervention in asthma, carried out with asthmatic and non-asthmatic adolescents. The study participants were divided into a curricular intervention group for asthma (IG), and a control group with traditional curriculum (CG). Topics related to asthma were included in the curriculum, such as the disease concept, triggering factors, treatment, symptoms, action plan, and beliefs in popular myths about the disease. These topics were evaluated through a questionnaire with scores ranging from 0 to 20 points, expressed by the mean score. The acquisition of knowledge was evaluated 90 days and 540 days after the start of the intervention (baseline), by applying the mixed linear model for analysis of associations.

Results

181 students participated in the study (IG = 101 and CG = 80). As shown by their scores before the intervention; the students were unaware about asthma (IG: x=10.7±2.9 vs. CG: x=11.5±2.7 points), its treatment (IG: x=1.6±0.9 vs. CG: x=1.6±0.8 points), and reported beliefs in popular myths about the disease (IG: x=1.5±1.1 vs. CG: x=1.7±1.1 points). After the intervention, the IG showed higher overall knowledge (GI: x=15.5±3.1 points), as well as knowledge about the treatment (GI: x=2.5±1.0 points), and two times more knowledge in the field "beliefs in popular myths about the disease" when compared to the CG. A greater probability of achieving satisfactory knowledge about asthma was noted in the IG (RR = 3.5), with NTT = 2.0.

Conclusion

The inclusion of the asthma topic in the curriculum improved knowledge about the disease in a subgroup of students.
