[Adolescent pregnancy: its causes and repercussions in the dyad].

Teen pregnancy (TP) is a global public health problem that affects the physical and emotional health, educational and economic status of prospective parents and often also affects the product of gestation. In most cases, the TP is an unplanned event, and often difficult to accept by the couple. But it is more complicated for the future mother who suddenly finds herself without the protection of the couple, her family and her school companions. The risks to which the young mothers are exposed are diverse, but include: submitting to a clandestine abortion, falling into drug addiction, prostitution and crime; Also, it should be noted that with so many adversities, she can develop child maltreatment and frequently, she may be attacked at home, at school or in society giving rise to the twin phenomena of child abuse. To address this problem, it is necessary to develop preventive strategies aimed at risk of early pregnancy or acquiring sexually transmitted diseases by implementing educational programs for personal, family or schools for this age group range. It stresses the need for these programs to be consistent and persistent, as a basic strategy to reduce the consequent risks to unplanned or accepted sex life.
