Biodemographic Analysis of Factors Related to Perinatal Mortality in Portugal (1988–2011)

Abstract

Background. The purpose of this paper is to determine the relative mortality risks at delivery and during the first week of life with regard to maternal and foetal characteristics. Methods. Yearly individual digital records on live births and early neonatal mortality were used to infer the possible factors involved in perinatal deaths. Results. The results show that the number of births per year declined with time throughout the period studied. At the same time, rates decreased in 66.4% for stillbirths and in 70.2% for early neonatal mortality. Logistic regressions modelled the interaction of the two mortality indicators and covariables such as birth weight and the duration of gestation. Conclusions. This research provides a first biodemographic approach to the knowledge of factors influencing perinatal mortality in Portugal based on a set of foetal and maternal variables. Although the magnitude of the different perinatal mortality rates may be affected by the criteria used for selecting cases (multiple-singletons; minimum birth weight or minimum duration of gestation), one of the conclusions of the present analysis is that the relationship among the maternal and foetal variables that determine the relative risk remains unaltered. Certain resemblance with the factors determining negative birth outcomes in Spain is appreciated.

Magnitude and Determinants of Perinatal Mortality in Southwest Ethiopia

“…Twin pregnancies were more than five times at risk of ending in perinatal mortality. This is also consistent with the findings of studies conducted in North Shoa, Ethiopia [ 9 ], in India [ 15 ], and in Portugal [ 17 ]. This can be explained by the fact that mothers with a twin pregnancy are more likely to face complications during pregnancy as well as childbirth, including obstructed labor and birth asphyxia which leads to either stillbirth or early neonatal death.…”

Bayesian multilevel model application on determinants of perinatal mortality in Ethiopia using 2011 and 2016 EDHS data

“…The perinatal mortality of a child from a mother who used piped source of water has less risk of mortality as compared to mothers who used other sources of drinking water in both survey data and this finding is consistent with (UN, 2013;Ezeh et al, 2014;Adewuyi et al, 2017). The perinatal mortality of a child from a mother aged 15-19 is higher than a child from a mother aged 20-29, 30-39 and 40-49 for 2011survey data and this result is inconsistent with the findings of (Agrawal and Bhatnagar, 2017;Fuster, 2016). Family size was also a significant determinant factor of the perinatal mortality.…”

Mortalidad evitable en la vigilancia de la mortalidad perinatal y neonatal, Colombia, 2017 y 2018

“…Con relación al momento de ocurrencia de la defunción, la tasa de muerte evitable es mayor en las defunciones fetales anteparto (6,6 y 6,3 muertes por 1.000 nacidos vivos), lo que tiene una posible relación con las deficiencias en la salud materna (razón de mortalidad evitable 7,6 muertes por 1.000 nacidos vivos) junto con el bajo acceso, cobertura y calidad de los programas de atención prenatal (razón de mortalidad evitable 2,9 muertes por 1.000 nacidos vivos). Lo anterior coincide con lo reportado por la literatura, la cual ha descrito que los factores de riesgo identificados como modificables deben ser identificados y controlados desde la etapa preconcepcional, tales como la edad de embarazo de la mujer, hábitos de fumar, estados nutricionales, presencia de enfermedades crónicas (diabetes o hipertensión arterial), ausencia de controles prenatales, cortos periodos intergenésicos, duración de la gestación y multiplicidad de esta, antecedente de muerte fetal [33][34][35][36][37][38][39] .…”
