Relação entre sintomas vestíbulo-visuais e exposição a telas na população infantojuvenil

Abstract

Objective: To characterize and compare the presence of visually induced vertigo among children and adolescents exposed to screen time. Method: Analytical, cross-sectional, field survey study with a quantitative approach, approved by the Research Ethics Committee (nº 6.743.915). Data collection was performed using a Google Forms form, through anamnesis and the Pediatric Questionnaire on Visually Induced Dizziness (PVID). The sample consisted of responses from guardians of children and adolescents aged 6 to 18 years, of both sexes, who used screen time. Descriptive and inferential analysis was performed using the Mann-Whitney test, Fisher's exact test and the chi-square test. A significance level of less than 5% was considered. Results: There were 102 responses, 61 (59.8%) from the child group, with a mean age of 8.38 years, and 41 (40.2%) from the adolescent group, with a mean age of 14.56 years. Regarding the frequency of symptoms associated with screen use, 34 (55.7%) of the children and 33 (80.5%) of the adolescents reported the presence of symptoms. A statistical difference was observed between the child and adolescent groups for the time of screen use and the total PVID. An association was identified between the occurrence of nausea after screen use in adolescents and a higher incidence of headache after screen use for more than two hours in children. Conclusion: This study identified a statistical difference in the time of exposure to screens between the groups and in the presence of vestibular-visual symptoms between the groups, through the PVID. Adolescents presented greater time of exposure to screens and a greater predominance of vestibular-visual symptoms, which suggests the presence of visually induced vertigo in this population.
