Risk factors for perinatal mortality in Murmansk County, Russia: a registry-based study

Abstract

Background: Factors contributing to perinatal mortality (PM) in Northwest Russia remain unclear. This study investigated possible associations between selected maternal and fetal characteristics and PM based on data from the population-based Murmansk County Birth Registry. Objective: This study investigated possible associations between selected maternal and fetal characteristics and PM based on data from the population-based Murmansk County Birth Registry. Methods: The study population consisted of all live- and stillbirths registered in the Murmansk County Birth Registry during 2006–2011 (n = 52,806). We excluded multiple births, births prior to 22 and after 45 completed weeks of gestation, infants with congenital malformations, and births with missing information regarding gestational age (a total of n = 3,666) and/or the studied characteristics (n = 2,356). Possible associations between maternal socio-demographic and lifestyle characteristics, maternal pre-pregnancy characteristics, pregnancy characteristics, and PM were studied by multivariable logistic regression. Crude and adjusted odds ratios with 95% confidence intervals were calculated. Results: Of the 49,140 births eligible for prevalence analysis, 338 were identified as perinatal deaths (6.9 per 1,000 births). After adjustment for other factors, maternal low education level, prior preterm delivery, spontaneous or induced abortions, antepartum hemorrhage, antenatally detected or suspected fetal growth retardation, and alcohol abuse during pregnancy all significantly increased the risk of PM. We observed a higher risk of PM in unmarried women, as well as overweight or obese mothers. Maternal underweight reduced the risk of PM. Conclusions: Our results suggest that both social and medical factors are important correlates of perinatal mortality in Northwest Russia.

Community-and proximate-level factors associated with perinatal mortality in Nigeria: evidence from a nationwide household survey

“…Babies born to obese mothers had a 1.46 times greater risk of dying in the perinatal period than those having normal MBMI (18.5 ≤ MBMI ≤24.9). Similar findings were reported in earlier studies conducted in both developing and developed countries Nigeria [22], sub-Saharan Africa [23], Russia [24] and Sweden [25]. An increased likelihood of perinatal deaths for babies born to obese mothers may be attributed to undiagnosed diabetes, gestational diabetes or prediabetic hyperglycaemia, hypertension and large-for-gestational-age birth, which were previously found to be associated with foetal or newborn deaths [26].…”

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

“…This finding is supported by the study (Adewuyi and Lamichhane, 2016). In 2016 survey data, perinatal mortality is higher for children from cigarette smoking mother compared with children from non-smoking mother and this result was similar with the findings of (Usynina et al, 2017). From the result of Bayesian multilevel empty model we found that the perinatal mortality heterogeneity between regions for both 2011 and 2016 survey data.…”

“…It is defined as a period between 22 weeks of gestation and seven days after live birth (Siddalingappa et al, 2013). Sociodemographic factors, general health status, as well as availability and quality of medical care associate with pregnancy outcomes and the impact of these factors on perinatal mortality varies within and between countries (Usynina et al, 2017) .…”

Perinatal outcomes in pregnant patients presenting with antepartum hemorrhage: Our experiences at a teaching hospital in Central Punjab.

“…A study from Nigeria 11 also revealed a perinatal mortality rate of 42.8% in antepartum hemorrhage while Singhal et al 12 reported a perinatal mortality of 23.70% and Usynina et al reported a perinatal mortality of only 4.7% from Russia. 15 Thus a lot of effort is needed to bring the perinatal mortality in patients presenting with antepartum hemorrhage in developing countries like Pakistan at par with the developed world.…”
