<span name="style_bold">Aim: </span>To examine the characteristics of prenatal control and delivery in the immigrant population that gives birth at the "Rafael Angel Calderon Guardia Hospital (HCG), Costa Rica.

The majority of these immigrants are young, multiparous, Nicaraguan women with adequate prenatal control.

It is also noteworthy to mention that half of the immigrant patients began their prenatal control after 13 weeks of gestation, and, had a less prenatal consults than the Costa Rican population. This finding does not seem to have any influence over delivery or neonatal outcomes in the immigrant population. <span name="style_bold"/> <span name="style_bold">Conclusion: </span>There are no significant medical differences between the immigrant population that gives birth at the HCG and the native Costa Rican population.There are no significant medical differences between the immigrant population that gives birth at the HCG and the native Costa Rican population.
