Objective: Sleep problems are highly prevalent and impairing in adolescents with ADHD. However, their relation with co-occurring mental health problems is still unclear.

Background: Adolescence is characterized by an increase in the rate of sleep problems, which might be even more pronounced in adolescents with ADHD. This systematic review with meta-analysis aimed to compare sleep in adolescents with and without ADHD, including sleep parameters, both subjectively and objectively measured, sleep problems and sleep hygiene.

Methods: Medline, CINAHL, PsycINFO, EMBASE, ERIC, Web of Science, and PubMed databases were searched for studies with case-control designs (published between 1980 and 2022) directly comparing sleep in adolescents (12-25 years) with ADHD to typically developing controls.
