Abstract
Adolescent pregnancy is generally an unwanted pregnancy, a situation that involves significant biological, psychological and social overloads, with repercussions on the health of the mother and the child. But the psychosocially important fact is that an unwanted pregnancy in its entirety gives rise to the birth of an ambivalently wanted child, a high-risk child. Those born in Spain in 2020 to women under 20 years of age were 8,305, which corresponds to 1.97% of all births. This review presents measures and recommendations for the protection and prevention of the mental health of the mother and child when pregnancy takes place in adolescence.
