Data were collected via questionnaires on sociodemographic characteristics, self\u2010medication and the Paediatric Migraine Disability Assessment.

Most attended school full\u2010time (61.6%), had employed guardians (57.5%) and had a family income around the minimum wage (44.3%). Possible sleep bruxism was identified in 10.6% of adolescents, while headaches affected 40.6%. Over\u2010the\u2010counter medication use was reported by 70.2%, with 68.8% specifically self\u2010medicating for headaches.
