Resumen
Methodology: The review was conducted through electronic searches of various articles related to maternal risk factors associated with intrauterine fetal growth restriction (IUGR). The search sources were PUBMED, EMBASE, and Google Scholar. The descriptors used for information retrieval were the key terms: maternal risk factors and intrauterine fetal growth restriction. Articles published with research results from 2014 to 2021 were selected. Results: Thirty-one observational studies were selected. The prevalence of IUGR according to different authors ranges from 3.7% to 22.4%. In Peru, it is reported to range from 4.8% to 10.1%. Obstetric factors associated with IUGR were: adolescent age with an odds ratio (OR) of 1.26 to OR = 28.30; advanced maternal age with OR = 1.05 to OR = 9.1; prenatal control <7 visits with OR = 1.29 to OR = 6.43; short intergenetic period with OR = 1.78 to OR = 13.16; and pregestational maternal weight <50 kg with OR = 1.70 to OR = 8.60. Obstetric pathology factors associated with IUGR in most of the selected studies report preeclampsia with OR = 1.69 to OR = 66.54; anemia during pregnancy with OR = 2.18 to OR = 9.70; previous IUGR with OR = 3.26 to OR = 14.49; and preterm birth with OR = 3.58 to OR = 14.60. Conclusions: The prevalence of IUGR ranges from 3.7% to 22.4%. The main associated factors include extreme ages, insufficient prenatal control, short intergenetic period, and obstetric factors such as preeclampsia, anemia during pregnancy, and a history of IUGR.
