Aimed at identifying the epidemiological factors associated with placenta previa a retrospective, cross-sectional and analytical study (cases and controls) was conducted at "Abel Santamaria Cuadrado" University Hospital during April 2006-2007. The study group was comprised of 19 pregnant patients with placenta previa and 60 belonging to control group that were not included in the diagnosis. Variables of mothers, pregnancy, birth and newborn were studied. The empirical method of measurement using the descriptive and inferential statistics was applied; as well as percentage, chi square test (X²), a level of significance p <0,05; also the odds ratio (OR) with a confidence interval of 95% (CI 95%). The maternal age frequently associated with placenta previa was 25-34 years old. The main epidemiological factors taken as risks were: urban origin (OR=1,7), malnutrition for lack (OR=6,61) and for excess (OR=3,93), multiparity (OR=1,55), history of abortions (OR=5,08) and a previous cesarean section (OR=3,21); besides cesarean section as a way to end pregnancy (OR=13,67**) it was very conducive for child-maternal morbility and mortality.

Keywords : Placenta Previa; Multiparity; Way Of Ending Pregnancy.
