Determinants factors in the recognition of a usual source of care by Brazilian adolescents.

The present study aimed to analyze the demographic, socioeconomic, and health factors and risk behaviors associated with the recognition of a Usual Source of Care (USC), according to gender. This work was a cross-sectional study, based on the National Survey of School Health (2015), conducted with 100,464 Brazilian adolescents. Descriptive analyses were performed based on Pearson's χ2, and the prevalence ratio (PR) through logistic regression models in Stata 14 for each type of USC (Primary Health Care (PHC), Private Practice, Hospital, and Emergency), stratified by sex. Recognition of a USC was reported by 55.5% of the adolescents, 58.6% of whom were female. In the multivariate analysis, the variables that present social, economic, and risk behavior inequalities showed positive associations for USC PHC for both genders. For the other types of USC, the demographic and socioeconomic characteristics showed negative associations. The results of this study showed that PHC is the service with the highest recognition among adolescents in conditions of social vulnerability. This reinforces the need to consolidate the PHC in order to favor the health care of adolescents, establishing bonds and improving access to health actions.
