Demand for health services or professionals among adolescents: a multilevel study.

This study aimed to analyze the demand for health services or professionals by adolescents with individual determinants and contextual variables (school teaching modality and Social Vulnerability Index). Data were collected from March to June 2018, in state public schools in Olinda, Pernambuco, Brazil, through a structured questionnaire with questions from the Youth Risk Behavior Survey (YRBS) and the National School Health Survey (PeNSE). Among the 2,454 adolescents, the proportion of those looking for a health service was higher among women; in adolescents whose mothers had a minimum of nine schooling years; in the physically active; and whose parents did not receive a family aid (Bolsa Família).
