ABSTRACT

Objetive: To identify if there is a relationship between the low pre-conceptional body mass index and the risk of preterm delivery and / or PROM.
Materials and Methods: Analytical cross-sectional study was conducted with a random sample of 120 patients treated between January 2015 to January 2016. Patients were analyzed for age, body mass index, and weight gain during pregnancy, history of urinary tract infection, vaginal infections, threat of abortion and premature rupture of membranes. The analysis was performed using a generalized linear regression model to identify the influence of body mass index and the rest of the variables studied on the risk of preterm delivery.
Results: The generalized linear regression showed a statistically significant relationship between the pre gestational body mass index and the risk of preterm delivery. (R2 = 0.016, p = ‹0.001)
Conclusion: Body mass index influenced the risk of preterm delivery but not premature rupture of preterm membranes.
