Guardian's knowledge and attitude towards inhaled corticosteroids aerosol therapy and medication compliance of children with wheezing diseases.

Background: Glucocorticoids are widely used in inhalation aerosol therapy for wheezing diseases. This study aims to explore guardians' knowledge and attitude towards inhaled corticosteroids (ICS) aerosol therapy and the medication compliance of children with wheezing diseases in China.

Methods: This cross-sectional study enrolled guardians of children with wheezing diseases at the First Hospital Affiliated to Shaoyang College between October 2022 and February 2023. A self-administered questionnaire was developed to collect demographic information of the participants and evaluate their knowledge and attitude towards ICS aerosol therapy. The 8-item Morisky Medication Adherence Scale was used to assess the medication compliance of children.

Results: A total of 506 valid questionnaires were collected. 260 (51.38%) participants were guardians of a ≤ 3-year-old child and 327 (64.62%) were children's mothers. The knowledge, attitude, and medication compliance scores of all participants were 12.61 ± 5.78, 20.95 ± 2.37, and 4.69 ± 2.18, respectively. Multivariate logistic regression showed that knowledge scores [OR = 1.053, 95% CI (confidence interval): 1.017-1.090, P = 0.003], attitude scores (OR = 1.121, 95% CI: 1.030-1.219, P = 0.008), guardians of children aged 4-6 years (OR = 0.385, 95% CI: 0.242-0.612, P < 0.001), and grandparents of children (OR = 2.633, 95% CI: 1.104-6.275, P = 0.029) were independently associated with children's medication compliance.

Conclusions: In conclusion, guardians of children with wheezing diseases in China had insufficient knowledge, unsatisfactory attitude, and poor medication compliance towards ICS aerosol therapy.
