Factors associated to fetal death in Cuiabá, Mato Grosso

Abstract

Abstract Objectives: to investigate the causes and the factors associated to fetal death in Cuiaba, Mato Grosso, 2006-2010. Methods: a population based case-control study in a ratio of 1:3 (300:900), was based on secondary data on Live Births and Mortality Information Systems. A hierarchical logistic regression was used. Results: remains independently associated to fetal death: low maternal schooling (OR=1.58, CI95%=1.02;2.47), low weight (OR=5.59, CI95%=3.22;9.70) gestational age <37 weeks (OR=9.34, CI95%=5.38;16.21), previous fetal death (OR=6.65, CI95%=4.35;10.15). The type of cesarean delivery remained as a protective factor (OR=0.35, CI95%=0.24;0.54). The main causes of fetal deaths were by unspecified cause (15.4%), followed by maternal hypertensive disorders (14.7%). The fetal mortality rate (TMF) decreased from 10.0 in 2006 to 7.5 deaths per thousand births in 2010 (decreased 24.5%). The TMF during the study period was below the goal set for 2030 by the World Health Organization. Conclusions: approximately one third of fetal deaths causes were potentially avoidable. Factors such as low maternal schooling, low birth weight, prematurity and previous fetal death history constitute as main determinants for fetal deaths in Cuiaba and suggests that socioeconomic situation still determines quality care for pregnant women and that actions should be directed to improve prenatal care.
