OBJECTIVE. To determine the risk factors of intrauterine fetal death in a Northern Peruvian population. DESIGN: Retrospective, analytical, case control study of intrauterine fetal death in 2,743 deliveries with newborn weights 500 g or more and/or over 19 weeks gestation ATTENDED AT HOSPITAL DE APOYO III, SULLANA, PERÚ, BETWEEN JUNE 1994 AND JUNE 1995. Data were obtained by the CLAP Perinatal Informatic System. RESULTY: The 92 dead newborns gave a fetal death rate of 33,5 per 1000 newborns; 53,6% occurred during pregnancy, 30,4% in an unknown moment and 11,9% during delivery. Causes of intrauterine death were infections (44,6%), hemorrage (25%) and hipertension (9,8%). Cause of death was not determined in 16,3%. Risk factors of fetal death were: a) Maternal: multiparity (RR 1,65), induced delivery (RR 7,75), PNC (RR 0,44), breech (RR 2,95) and transverse PRESENTATION (RR 4,56), preterm ...

Objective: To determine low newborn weight risk factors (LBW). Setting: Hospital Apoyo III, Ministry of Health, Sullana northern Peruvian urban City. Design: Transversal, retrospective, analytical, case-control study. Material and methods: One thousand five hundred and thirty-six LBW in 15318 newborns delivered between June 1994 and December 1999. Information was obtained from Perinatal Informatic System. Analysis used programs EPI INFO and SPSS 10,1. Results: LBW incidence was 10,02%. Preconceptional causes were nulliparity, maternal size below 1,50 m, age below 19 years; conceptional causes were maternal pathology, non- or inadequate prenatal control. Maternal pathologies were anemia, urinary tract infection, preeclampsia and premature rupture of membranes. Conclusions: Preconceptional risk factors were previous arterial hypertension, maternal weight and size, being illiterate and null...

El presente trabajo de investigación se realizó en la Estación Experimental Agraria Canaán - INIA, en dos épocas de siembra. Los objetivos fueron: a) Caracterizar los estados fenológicos de cuatro variedades de quinua en dos épocas de siembra, b) Evaluar el efecto de la temperatura y precipitación, c) Evaluar el efecto de la radiación solar en los diferentes estados de crecimiento y desarrollo en cuatro variedades de quinua, d) Determinar la evapotranspiración potencial del cultivo y eficiencia de uso del agua de la variedad Blanca de Junín mejorado y e) Determinar la variedad de quinua de mejor rendimiento bajo las condiciones climáticas de nuestra zona. Los tratamientos fueron Blanca de Junín, Killahuamán, Pasankalla y Salcedo INIA, en dos épocas de siembra. Se empleó el diseño bloque completo randomizado, con arreglo factorial de variedades por épocas de siembra con ...
