Oral Health Literacy, Sense of Coherence and Associations With Poor School Performance.

BACKGROUND This study aimed to investigate the associations of oral health literacy (OHL), sense of coherence (SOC) and other covariates with self-reported school performance (SRSP) in adolescents enrolled in public schools in Brazil. METHODS This was a cross-sectional study conducted with adolescents aged from 14 to 18 years enrolled in 6 public schools in Piracicaba, São Paulo, Brazil. Researchers carried out data collection at schools using a self-administered structured questionnaire. The dependent variable was SRSP. The explanatory factors included were sociodemographic characteristics, OHL, SOC, self-rated oral health, health behaviors, and experience of bullying. Analyses included simple and multiple logistic regression models. RESULTS The final sample consisted of 385 adolescents with a mean age of 16 years. Poor school performance was associated (95%CI) with being male, with more than 1 sibling, individual whose last visit to the dentist was due to dental pain, with a lower level of OHL and SOC. CONCLUSIONS OHL and SOC were important factors associated with SRSP performance together with other sociodemographic and oral health-related variables in high school students. Our findings reinforce the importance of intersectoral actions between the health and education sectors to promote better school performance among adolescents, including actions to improve OHL and SOC.
