ABSTRACT
Purpose
To investigate the association between functional health literacy and sociodemographic factors, quality of life, self-perception of health, and perception of contexts of violence in adolescents in state schools in Belo Horizonte.
Methods
This is a cross-sectional analytical observational study with a probabilistic sample of 384 adolescents between 15 and 19 years old. Data collection was carried out in schools and included self-reporting questionnaires to assess the functional health literacy, socioeconomic classification, self-perceived health, and quality of life. The reliability of internal consistency of the functional health literacy instrument was determined by calculating Cronbach's alpha coefficient. A multivariate logistic regression analysis was performed using hierarchical data entry according to the level of determination of the theoretical model established. In order to evaluate the association, a significance level of 5% was considered, while the Odds Ratio used as a measure of the magnitude of the associations.
Results
The functional health literacy instrument presented a coefficient of 0.766, indicating adequate internal consistency. More than half of teenagers presented good functional health literacy. In the final model of multivariate analysis, the variables not practicing a religion (p = 0.006; OR = 2.108); social domain of quality of life (p = 0.004; OR = 1.022); and educational domain of quality of life (p = 0.009; OR = 1.019) remained associated with functional health literacy.
Conclusion
Not practicing a religion and the increase in the scores of social and educational domains of quality of life increased the chances of better functional health literacy.
