RESUMO
Abstract Objective: To analyze whether demographic and socioeconomic factors can influence the OHRQoL in schoolchildren. Material and Methods: A cross-sectional study using a representative sample of 1137 children aged 8-10 years, enrolled in public schools in Florianópolis, Brazil, was conducted. Children answered the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) quality of life questionnaire and their parents responded to socioeconomic and demographic questions. Logistic regression models were used to analyze the data. Results: Higher probability of presenting a negative impact on the OHRQoL was observed in children whose skin color was non-white (OR 1.46, 95% CI 1.04-1.69) and female (OR 1.33, 95% CI 1.04-1.69). Children in whom the head of the family had years of schooling 9-11 (p=0.001), 5-8 (p=0.005) and ≤4 (p=0.000) were more likely to have a negative impact on the OHRQoL. CPQ8-10 domains evaluation showed that variables education, gender, skin color, and age were associated with a negative impact on OHRQoL (p≤0.05). Conclusion: The educational level of the head of the family and the demographic characteristics of the children are associated with a negative impact on the OHRQoL.
