Migraine can be triggered by many factors such as stress, sleep, fasting and environmental causes. There are few studies that evaluated migraine trigger factors in the adolescent population. Methods: A total of 100 participants from 10 to 19 years were subjected to a detailed headache questionnaire, with demographic and clinical data, and a headache diary including trigger factors during a two-month period was asked. Results: Fifty of the participants exhibited chronic migraine and the other 50 participants demonstrated episodic migraine. The most common group of trigger factors reported was the environmental one, mainly sun/clarity, followed by hot weather and the smell of perfume. Conclusions: Ninety-one percent of children and adolescents with migraine reported a trigger factor precipitating the migraine attack.<br>Crises de migr&#226;nea podem ser desencadeadas por muitos fatores, como estresse, sono, jejum e causas ambientais. Poucos estudos avaliaram os fatores desencadeantes de migr&#226;nea em adolescentes. M&#233;todos: Cem pacientes, de 10 a 19 anos, foram submetidos a um question&#225;rio detalhado sobre sua cefaleia, com dados demogr&#225;ficos e cl&#237;nicos e um di&#225;rio da cefaleia, incluindo perguntas sobre os fatores desencadeantes, por um per&#237;odo de dois meses. Resultados: Cinquenta pacientes apresentavam migr&#226;nea epis&#243;dica e 50, migr&#226;nea cr&#244;nica. O grupo de fatores desencadeantes mais frequentemente relatado foi o ambiental, principalmente sol ou claridade, seguido pelo clima quente e pelo cheiro de perfume. Conclus&#245;es: Noventa e um por cento dos adolescentes com migr&#226;nea relataram pelo menos um fator desencadeante de crises &#225;lgicas.
