Introduction:

Armed conflicts affect the mental health of children and adolescents. Their outcomes in these populations have been documented identifying vulnerability and significant biopsychosocial damage as the most common factors.

Objective:

To identify and synthesize the mental health consequences of armed conflicts in children and adolescents.

Materials and methods:

We carried out a comprehensive and systematic search of reviews published until July 2019 in the MEDLINE (Ovid), EMBASE, Cochrane Central Register of Controlled Trials, and LILACS databases, as well as in additional sources. The information was retrieved and analyzed narratively by describing the characteristics and objectives of the studies and the mental health consequences of armed conflicts in three periods of time: pre-armed conflict, during the armed conflict, and post-conflict.

Results.

Out of 587 potentially relevant studies, we finally selected 72. In the pre-armed conflict period, we described in detail the psychological experiences and the anticipatory somatic symptoms. During the conflict, we identified regressive, behavioral, and cognitive symptoms such as enuresis, fear, sadness, aggression, hyperactivity, and inattention, among others. Direct mental health consequences such as adjustment disorders, depression, anxiety, and post-traumatic stress were also identified. Finally, in the post-conflict period, we referred to the transmission of mental health consequences and resilience processes. On the other hand, we reviewed in depth the potential consequences of armed conflicts on biopsychosocial development, morality, identity, culture, education, and society.

Conclusion.

The development of mental health consequences due to the exposure to armed conflicts in these populations is a complex process that depends on the stage of the exposure, the length of the conflict, and contextual factors.
