The moderating effect of parental skills for antibiotic identification on the link between parental skills for antibiotic use and inappropriate antibiotic use for children in China

Abstract

BackgroundInappropriate antibiotic consumption promotes antibiotic resistance. However, findings on the association between antibiotic-related knowledge and behaviors are inconsistent and contradictory, resulting in unjustified guidance of interventions. The mechanisms between the different kinds of antibiotic-related skills contained in knowledge modules in some previous studies are indistinct and rarely studied.MethodsA cross-sectional survey was conducted between June 2017 and April 2018 in three Chinese provinces, investigating 9526 parents with children aged 0–13 years old. Data from 1944 parents who self-medicated their children and 2478 respondents whose children sought care were analyzed.ResultsSkills for antibiotic identification were found to be a moderator for the association between skills for antibiotic use and two inappropriate behaviors. Compared with parents with low levels of both skills for antibiotic identification and use, those mastering both skills at either medium (OR = 0.48, 95% CI [0.26–0.88]) or high (OR = 0.15, 95% CI [0.07–0.34]) level were less likely to self-medicate their children with antibiotics. Parents with a medium level of skills for antibiotic identification and high level of skills for antibiotic use (OR = 0.18, 95% CI [0.08–0.44]) and those with a high level of both skills (OR = 0.15, 95% CI [0.05–0.47]) were less likely to ask doctors for antibiotics when seeking care.ConclusionParents’ high level of skills for antibiotic identification is revealed to promote inappropriate antibiotic use when parents master a low level of skills for antibiotic use. Conversely, based on excellent skills for antibiotic use, better skill for antibiotic identification is associated with a greater reduction in inappropriate behaviors. We recommend future health education to strengthen skills for antibiotic identification along with guidance on antibiotic use.
