ABSTRACT

Resumen OBJETIVO: Determinar los factores de riesgo asociados con ruptura prematura de membranas pretérmino. MATERIALES Y MÉTODOS: Estudio observacional, analítico, de casos y controles, retrospectivo y transversal, efectuado en pacientes embarazadas atendidas en 2017 en el Hospital San José del Callao, Perú. Se estudiaron factores sociodemográficos y obstétricos. Para el análisis estadístico bivariado se aplicó χ2, razón de momios con intervalo de confianza; y para el análisis multivariado la prueba de regresión logística binaria. RESULTADOS: Se estudiaron 32 pacientes embarazadas, con ruptura prematura de membranas pretérmino (casos) y 64 embarazadas sin enfermedad (controles). Entre los factores estudiados, los sociodemográficos no demostraron asociación significativa; mientras que los factores obstétricos: infecciones cervicovaginales (ORa: 6.9; IC95%: 1.6-29.2), infección de vías urinarias (ORa: 5.1; IC95%: 1.5-17.2) y anemia (odds ratio ajustado (ORa). 6.9) 4.8; IC95%: 1.6-14.2) demostraron incrementar, significativamente, el riesgo de ruptura prematura de membranas pretérmino cuando una embarazada está expuesta a esos riesgos. CONCLUSIONES: Las infecciones cervicovaginales, urinarias y la anemia fueron factores de riesgo que se asociaron con la ruptura prematura de membranas pretérmino.


Abstract OBJECTIVE: Determine the risk factors associated with preterm premature rupture of membranes. MATERIALS AND METHODS: An observational, analytical study design of cases and controls, retrospective and transversal, carried out in pregnant women treated in 2017 at the San José Hospital, Callao, Peru. Sociodemographic and obstetric factors were studied. For the bivariate statistical analysis, the chi-square test was applied χ2, the Odds ratio with its confidence intervals; and for multivariate analysis, the binary logistic regression test. RESULTS: The sample was 32 pregnant women with Preterm Premature Rupture of Membranes (cases) and 64 pregnant women without pathologies (controls). Among the factors studied, the sociodemographic ones showed no significant association; while obstetric factors such as vaginal cervical infections (ORa: 6.9; CI 95%: 1.6-29.2), urinary tract infection (ORa: 5.1; CI 95%: 1.5-17.2) and anemia (ORa: 4.8; CI 95%: 1.6-14.2) showed a significant increase in the risk of preterm premature rupture of membranes when a pregnant woman is exposed to them. CONCLUSIONS: Vaginal cervical infections, urinary tract infection and anemia were risk factors associated with Preterm Premature Rupture of Membranes in the study group.
