Changes in parental knowledge and concerns regarding pediatric fever from 2017 to 2024: repeated cross-sectional surveys on the association of a smartphone application

Over the past 7 years, an increase in parents' knowledge of fever and an escalation in their anxiety were observed. However, the dissemination of the application alone did not demonstrate an effect strong enough to offset the overall increase in societal anxiety. Future studies may be able to more clearly verify a suppressive effect on this increase by using more refined exposure measurements based on behavioral indicators, such as actual frequency of use, including by expanding the sample size.
