Abstract

ObjectiveAlterations in behavioral habits of children were analyzed in Shanghai in the winters prior to and following the COVID-19 pandemic, with the aim of assisting in the prevention of children's respiratory diseases in the post-pandemic era. MethodThis cross-sectional survey was conducted via an offline questionnaire from January 1 to February 28, 2021. The behavioral habits of Shanghainese children in different age groups during the winter of 2019 and 2020 were statistically analyzed using the SPSS 25.0 software. The parameters surveyed and analyzed included the frequency of outdoor activities, self-protection measures (frequency of wearing masks and washing hands after going out), travel history, time to visit since symptom onset, and influenza vaccination status. Lastly, the number of cases of respiratory diseases in the pediatric outpatient department of our hospital was analyzed during the same period. ResultA total of 1816 questionnaires were investigated and analyzed, and the results revealed that self-protection measures were significantly enhanced in children of all age groups after the COVID-19 pandemic breakout compared with those before the pandemic, whereas the frequency of outdoor activities and traveling were reduced. In the age group over 3 years old, the time to visit since symptom onset was shorter, and the influenza vaccination rate increased following the pandemic. During the same period, the number of cases of children with respiratory diseases in our outpatient department was significantly decreased compared with that prior to the COVID-19 pandemic. ConclusionThe COVID-19 pandemic has had a significant impact on self-protection measures, outdoor activities, and other children's behaviors in all age groups in Shanghai. These changes in habits were correlated with a lower incidence and transmission of respiratory diseases in children. Overall, this study lays a theoretical basis for the prevention of childhood illnesses in the post-pandemic era.
