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.
We explored factors associated with influenza vaccination coverage among adolescents with asthma.
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.
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.
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.
