ABSTRACT
OBJECTIVES: To estimate the prevalence for the attempts to stop pregnancy among women with history of previous pregnancies, and to determine the factors associated. MATERIAL AND METHODS: A cross-sectional study was performed during 2006. Samples included 1057 women with background of pregnancy, living in Pamplona Alta, selected by a systematic random sampling. We applied descriptive and inferential statistics, including a logistic regression model. RESULTS: The prevalence for the attempt to stop pregnancy was 13.9% (99% CI: 11.1-16.7). The factors associated identified by multivariate analysis were: Unwanted pregnancy (OR=5.7; CI: 1.9-16.7), lack of pre-natal care (OR=4.7; CI: 1.8-12.2), prostitution (OR=11.4; CI: 1.5-87.9), age below 20 years (OR=2.9; CI: 1.1-7.9), and having more than two partners (OR=3.3; CI: 1.1-10.2). CONCLUSIONS: The estimated prevalence for the attempt to stop pregnancy among women with history of previous pregnancies in a marginal suburban area from Lima was low when compared to the national estimated prevalence of abortion. The associated factors identified for the attempts to stop pregnancy are: unwanted pregnancy, prostitution, age below 20 years, having more than two partners and lack of pre-natal care.

Objetivos. Estimar la prevalencia y determinar los factores asociados al intento de interrumpir el embarazo en mujeres con antecedente de embarazo. Material y métodos. Se realizó un estudio transversal durante el año 2006. La muestra incluyó a 1057 mujeres con antecedente de embarazo que habitaban en Pamplona Alta, seleccionadas a través del muestreo probabilístico sistemático. Se realizó análisis estadístico descriptivo e inferencial, incluyendo un modelo deregresión logística. Resultados. La prevalencia de la intención de interrumpir su embarazo fue 13,9 por ciento (IC99 por ciento: 11,1- 16,7). Al efectuarse un análisis multivariado, se encontró que los factores asociados fueron: embarazo no deseado (OR=5,7; IC: 1,9-16,7), la falta de atención prenatal (OR=4,7; IC: 1,8-12,2), la prostitución (OR=11,4; IC: 1,5-87,9), tener menos de 20 años (OR=2,9; IC: 1,1-7,9) y tener más de dos parejas (OR=3,3; IC: 1,1-10,2). Conclusiones. La prevalencia estimada del intento de interrumpir el embarazo en mujeres con antecedente de embarazo en una zona urbano marginal de Lima es baja si se compara al estimado nacional de abortos. Los factores asociados al intento de interrumpir el embarazo son: el embarazo no deseado, prostitución, tener menos de 20 años, tener más de dos parejas y la falta de atención prenatal.

A cross-sectional study was performed during 2006. Samples included 1057 women with background of pregnancy, living in Pamplona Alta, selected by a systematic random sampling. We applied descriptive and inferential statistics, including a logistic regression model. Results. The prevalence for the attempt to stop pregnancy was 13.9 per cent (99 per cent CI: 11.1-16.7). The factors associated identified by multivariate analysis were: Unwanted pregnancy (OR=5.7; CI: 1.9-16.7), lack of pre-natal care (OR=4.7; CI: 1.8-12.2), prostitution (OR=11.4; CI: 1.5-87.9), age below 20 years (OR=2.9; CI: 1.1-7.9), and having more than two partners (OR=3.3; CI: 1.1-10.2).

Estudiamos la seroprevalencia y factores de riesgo para infección con virus de hepatitis E en 191 sujetos de sexo masculino, trabajadores de la empresa del servicio de agua potable y alcantarillado de Lima cuya principal activdad laboral consistía en la manipulación de cañerías de aguas en el presente o en el pasado inmediato. Se determinó el anticuerpo contra hepatitis E de tipo IgG utilizando el método enzima inmuno ensayo (ELISA) basado en 2 antígenos recombinantes expresados en E. coli de la casa Abbott.(Il.USA). El anti-HVE IgG fue detectado en 20 de 1991 sujetos (10.47 por ciento) y de las variables independientes evaluados como factores de riesgo, sólo se encontró una relación con el tiempo de servicio en la empresa cuando estaba en el rango de 13 a 20 años. Se concluye que la hepatitis E es una infección endémica en este grupo de población y su prevalencia está asociado al tiempo que labora en ese tipo de actividades. Son necesarios estudios de prevalencia en otros grupos de población, para conocer la magnitud de la infección por el virus de hepatitis E en el Perú.

We study the seroprevalence and risk factors on hepatitis E virus infection in 191 healthy subjects, which are workers of the drinking water and sewerage system of Lima city, and the main activity of them was to handle sewage at present or early past. We tested for IgG hepatitis E antibodies (anti-HEV IgG) a two recombinant antigen based enzyme immunoassay (Abbott IL USA).Anti-HEV IgG were positive in 20 subjects (10.47%) and the only one variate that we can consider related to HEV infection was rank of years worked in the company, especially when reaching 13-20 years. We conclude that hepatitis E is a endemic infection in this kind of population and the prevalence of hepatitis E infection was related to the period worked in the company.We need several prevalence studies in other kind of population in order to know the magnitude of hepatitis E infection in Peru.
