COMPARISON OF NUTRITIONAL STATUS Y PERINATAL OUTCOMES BETWEEN IMMIGRANT AND CHILEAN PREGNANT WOMEN WHO ATTENDED THEIR DELIVERY AT SAN BORJA ARRIARAN HOSPITAL IN THE YEAR 2015

Background and objectives: The migration in Chile increased by 28% between the years 2012 and 2015. As there are no studies in the country that describe the pre-pregnancy nutritional status (NS) and perinatal outcomes of immigrant (GI) versus Chilean (GI) pregnant women, the objective of this study was to compare the NS and to analyze its association with maternal and newborn pathologies in GNI versus GI who attended their delivery at the Hospital Clinico San Borja Arriaran (2015). Methods: A comparative study carried out at 1,078 GI and 1,520 GNI. The data were obtained from: 1. the clinical records 2. The health agenda and a survey made to the pregnant woman. The variables studied were NS (underweight, normal, obesity and overweight) determined by Atalah standard; Gestational diabetes (GD), preeclampsia (PE), intrauterine growth retardation (IUGR) and preterm birth (PTB). Data were presented as prevalences and compared with CHI2 test. Crude and adjusted (by sociodemographic, obstetric and of maternal diseases variables) logistic regression models were performed to evaluate the association between NS and maternal and newborn pathologies. Results: The GNI had significantly more likely to have obesity 3.0 [2.4 - 3.8] and overweight 1.7 [1.4 - 2.1] at the beginning of gestation than GI, in relation to have a normal nutritional status (50% GI and 34% In GNI, p
