Abstract
Background:Influenza viral infection is a major public health problem with significant morbidity and mortality.Asthma is a risk factor for developing serious complications related to influenza infection. Objective: We explored factors associated with influenza vaccination coverage among adolescents with asthma. Methods: Data were obtained from 62,276 participants in the 13th Korean Youth Risk Behavior Web-Based Survey (KYRBS) conducted in 2017. KYRBS data were obtained from a stratified, multistage, clustered sample. We used multiple logistic regression analyses to identify variables potentially related to influenza vaccination in adolescents with asthma. Results: The proportion of asthma was 8.8%, and the influenza vaccination rate overall was 37.9%. It was 41.8% in the asthma group and 37.5% in the nonasthma group (p < 0.001). After regression, male sex (odds ratio (OR) = 1.45; 95% CI 1.35–1.55), a high socioeconomic status (OR = 1.12; 95% CI 1.05–1.19), residence at an orphanage (OR = 1.93; 95% CI 1.38–2.29), regular breakfast consumption (OR = 1.09; 95% CI 1.02–1.17), and subjective good health (OR = 2.39; 95% CI 1.69–3.39) were associated with increased influenza vaccination, whereas current smoking (OR = 0.87; 95% CI 0.67–0.96) and a depressive mood (OR = 0.77; 95% CI 0.64–0.95) were inversely associated in adolescents with asthma. Conclusion: It is important to improve influenza vaccination in adolescents with asthma, especially females, those with a low socioeconomic status, independent residents, breakfast skippers, current smokers, and those who consider themselves unhealthy and have depressive moods.
