Abstract
Introduction: Depending on the geographical altitude the purpose of this work was to analyze in two argentine populations the variation of birth weight (BW) and adverse perinatal outcomes, adjusting for maternal and obstetric factors. Material and Methods: Data from 4000 births in the provinces of Jujuy and 4000 in Buenos Aires (Sarda Maternity Hospital) (1996-2000) recruited and randomized from the Perinatal Information System was used. The data were grouped according to an altitudinal gradient composed by Sarda Maternity (20 masl) and the geographic regions of Jujuy province: Ramal (500 masl), Valle (1200 masl), Quebrada (2500 masl) and Puna (3500 masl). Outcome variables were BW > 3000 g, BW 3000 g, BW<2500g and PI were negatively associated with altitude (p <0.001). Prematurity, SGA and FGR showed an opposite trend (p <0.001). Adjusted for confounding variables BW <3000 g, SGA, FGR<0.90 and PI <2.53 showed an increased risk with geographical altitude (p <0.05). Conclusions: Altitude was independently associated with BW restriction and adverse perinatal outcomes. Given the impact of BW reduction in the risk of chronic no communicable diseases this relationship in other populations, regardless of their location altitude, should be assess.
