Anxiety and harmful oral habits in preschool children during the 2020 first-wave COVID‑19 lockdown in Turkey

BACKGROUND: Due to curfew and quarantine practices designed to reduce the spread of coronavirus disease 2019 (COVID‑19), social isolation has tested the psychological limits of children. OBJECTIVES: The authors evaluated parent-observed symptoms of anxiety in preschool children with harmful oral habits during the curfew period in Turkey. MATERIAL AND METHODS: The authors prepared a questionnaire with Google Forms that was distributed through social media applications (e.g., WhatsApp) to 405 parents recruited via snowball sampling. To measure children's symptoms and levels of anxiety, the Spence Preschool Anxiety Scale (SPAS) was used. Harmful oral habits that might develop in children during the curfew were investigated. RESULTS: Separation anxiety and physical injury anxiety were reported by the parents more frequently than general anxiety and obsessive-compulsive disorder. Also, the presence of tantrums (p = 0.010), crying attacks (p = 0.010) and aggression (p = 0.010) were reported by the parents in these children. It was observed that the habits of finger sucking (p = 0.010), nail biting (p = 0.040) and lip biting (p = 0.010) that were present before the curfew decreased significantly after the curfew. CONCLUSIONS: Children aged 3-7 years can develop anxiety about physical injuries and about being separated from their parents as well as tantrums and crying attacks. Their harmful oral habits (i.e., finger sucking, nail biting and lip biting) all decreased during the curfew period.
