Little is known about childhood and adolescent risk and prognostic factors for recurrent headaches. This systematic review: (1) Examined longitudinal evidence about factors associated with onset and course of recurrent headaches in childhood or adolescence, using meta-analysis where possible; and (2) Evaluated the quality of this evidence using a modified GRADE framework. Through searching electronic databases, reference lists of included studies, and an electronic mail list we identified and included 23 articles reporting 19 cohorts.
