Asthma prevalence and the relationship between level of knowledge and quality of life among asthmatic schoolchildren in Malaysia

OBJECTIVES: To examine asthma prevalence and the relationship between the level of knowledge and quality of life (QoL) among asthmatic secondary school children aged 13-14 years old in Malaysia. METHODS: A cross-sectional design was employed. Data was collected through a self-administered questionnaire containing demographic characteristics, asthma symptoms, knowledge on asthma, and QoL. RESULTS: Data from 2891 asthmatic schoolchildren aged 13-14 years old from secondary schools in Petaling Jaya, Malaysia, were analyzed. According to the International Study of Asthma and Allergies in Childhood (ISAAC) scoring for asthma prevalence, the number of children who exhibited signs and symptoms of asthma was 9% (n=260). The mean score for total knowledge indicated a low knowledge level (82.7%). No significant relationship was found between knowledge level and QoL. Only the race factor was associated with asthma knowledge. CONCLUSION: This study has provided valuable information on asthma prevalence among Malaysian adolescents and their knowledge on asthma condition. Further research should explore the correlation factors of asthma knowledge and QoL.
