Stillbirth and preterm birth and associated factors in one of the largest cities in central Vietnam

Stillbirth rates and their determinants in a national maternity hospital in Phnom Penh, Cambodia in 2017-2020: a cross-sectional assessment with a nested case-control study

BACKGROUND

In Cambodia, stillbirths and their underlying factors have not been systematically studied. This study aimed to assess the proportion and trends in stillbirths between 2017 and 2020 in a large maternity referral hospital in the country and identify their key determinants to inform future prevention efforts.

METHODS

This was a retrospective cross-sectional analysis with a nested case-control study of women giving birth at the National Maternal and Child Health Centre (NMCHC) in Phnom Penh, 2017-2020. We calculated percentages of singleton births at ≥ 22 weeks' gestation resulting in stillbirth and annual stillbirth rates by timing: intrapartum (fresh) or antepartum (macerated). Multivariable logistic regression was used to explore factors associated with stillbirth, where cases were all women who gave birth to a singleton stillborn baby in the 4-year period. One singleton live birth immediately following each case served as an unmatched control. Multiple imputation was used to handle missing data for gestational age.

RESULTS

Between 2017 and 2020, 3.2% of singleton births ended in stillbirth (938/29,742). The stillbirth rate increased from 24.8 per 1000 births in 2017 to 38.1 per 1000 births in 2020, largely due to an increase in intrapartum stillbirth rates which rose from 18.8 to 27.4 per 1000 births in the same period. The case-control study included 938 cases (stillbirth) and 938 controls (livebirths). Factors independently associated with stillbirth were maternal age ≥ 35 years compared to < 20 years (aOR: 1.82, 95%CI: 1.39, 2.38), extreme (aOR: 3.29, 95%CI: 2.37, 4.55) or moderate (aOR: 2.45, 95%CI: 1.74, 3.46) prematurity compared with full term, and small-for-gestational age (SGA) (aOR: 2.32, 1.71, 3.14) compared to average size-for-age. Breech/transverse births had nearly four times greater odds of stillbirth (aOR: 3.84, 95%CI: 2.78, 5.29), while caesarean section reduced the odds by half compared with vaginal birth (aOR: 0.50, 95%CI: 0.39, 0.64). A history of abnormal vaginal discharge increased odds of stillbirth (aOR: 1.42, 95%CI: 1.11, 1.81) as did a history of stillbirth (aOR: 3.08, 95%CI: 1.5, 6.5).

CONCLUSIONS

Stillbirth prevention in this maternity referral hospital in Cambodia requires strengthening preterm birth detection and management of SGA, intrapartum care, monitoring women with stillbirth history, management of breech births, and further investigation of high-risk referral cases.

Extended Perinatal Mortality Audit in a Rural Hospital in India

OBJECTIVE

The aim of the study is to describe the status of perinatal mortality (PM) in an Indian rural hospital.

STUDY DESIGN

Retrospective analysis of data was compiled from PM meetings (April 2017 to December 2018) following "Making Every Baby Count: audit and review of stillbirths and neonatal deaths (ENAP or Every Newborn Action Plan)."

RESULTS

The study includes 8,801 livebirths, 105 stillbirths (SBs); 74 antepartum stillbirths [ASBs], 22 intrapartum stillbirths [ISBs], and nine unknown timing stillbirths [USBs]), 39 neonatal deaths or NDs (perinatal death or PDs 144). The higher risks for ASBs were maternal age >34 years, previous history of death, and/or SBs. Almost half of the PDs could be related with antepartum complications. More than half of the ASB were related with preeclampsia/eclampsia and abruptio placentae; one-third of the ISB were related with preeclampsia/eclampsia and gestational hypertension, fetal growth restriction, and placental dysfunction. The main maternal conditions differed between PDs (p = 0.005). The main causes of the ND were infections, congenital malformations, complications of prematurity, intrapartum complications, and unknown. The stillbirth rate was 11.8/1,000 births, neonatal mortality rate 4.4/1,000 livebirths, and perinatal mortality rate 15.8/1,000 births.

CONCLUSION

This is the first study of its kind in Andhra Pradesh being the first step for the analysis and prevention of PM.

KEY POINTS

· Many conditions that lead to stillbirths are linked to neonatal deaths and PM has been outside of the global parameters from the last decades.. · This is the first study following International Classification of Disease perinatal mortality codes and the audit of ENAP in Andhra Pradesh.. · Extended PM and mortality are mainly caused by similar preventable and treatable conditions..

Factors associated with stillbirth in selected countries of South Asia: A systematic review of observational studies

BACKGROUND

Despite having the high rate of stillbirth in most of the countries of South Asia, there is a lack of synthesized evidence based on factors associated with stillbirth. This study systematically synthesizes the evidence on factors associated with stillbirth in the four selected countries of South Asia.

METHODS

This review was conducted using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Studies that examined factors associated with stillbirth in South Asia were searched using five major electronic search databases including MEDLINE, CINAHL, Embase, PsycINFO, and Scopus, published between January 2000 and December 2019. In the meta-analysis, significant heterogeneity was detected among studies (I2 >50%), and hence a random effect model was used.

RESULTS

A total of 20 studies met the inclusion criteria. The pooled rate of stillbirth from the studies in Bangladesh, India, Nepal, and Pakistan was 25.15 per 1000 births. Pregnancy complications, maternal health conditions, fetal complications, lack of antenatal care, and lower Socio Economic Status (SES) were the most common factors associated with stillbirth in countries of South Asia.

CONCLUSION

This study confirmed that stillbirth in selected countries of South Asia remains high. To reduce stillbirth, a greater focus needs to be on timely management of preterm labor, maternal hypertension, and provision of financial support for quality antenatal and delivery care. The interventions should be targeted for women living in remote areas, who are less educated and those with low SES.

Intimate partner violence during pregnancy and risk of still birth in hospitals of Tigray region Ethiopia

BACKGROUND

Pregnancy may represent a time of exceptional vulnerability to intimate partner violence because of changes in women's conditions. Despite the fact that intimate partner violence during pregnancy confers considerable risk to the health of the woman and her fetus, data regarding to association of stillbirth and intimate partner violence is lacking in Tigray region. The objective of this study is to assess intimate partner violence during pregnancy and its association with still birth among postpartum mothers in hospitals in Tigray Region of Ethiopia.

METHODS

Cross-sectional study design was used to assess 648 women about intimate partner violence during pregnancy and its association with still birth. Simple random sampling technique was employed to select health facilities and systematic sampling was used to select the study participants. Data was entered by using Epi info version 3.5.1 and analyzed using SPSS version 20. Logistic regression analysis was done to assess the association between exposure to intimate partner violence during pregnancy and stillbirth while adjusting for possible confounders.

RESULTS

The prevalence of still birth was 3.6%in this study population. There was a statistically significant association between exposure to intimate partner violence during pregnancy and still birth. Pregnant women who were exposed to intimate partner violence during pregnancy were three times more likely to have still birth 3.3(95% CI: 1.1-9.7) as compared to those who were not exposed. Another important factor associated with stillbirth was low birthweight 16.7(95% CI,6-46).

CONCLUSIONS

The prevalence of still birth in this study was high. Women who subjected to intimate partner violence during pregnancy had greater risk of having stillbirth baby.

High risk pregnancy associated perinatal morbidity and mortality: a second birth population-based survey in Huai'an in 2015

BACKGROUND

The objective of this survey was to explore the association between pregnancy complications and perinatal outcome from regionally total birth population.

METHODS

In this prospectively collected data of complete birth registries from all level I-III hospitals in Huai'an in 2015, perinatal morbidity and mortality in relation to pregnancy complications and perinatal outcome were analyzed using international definitions. The results were compared with that of 2010 survey in the same region.

RESULTS

Of 59,424 total births in the hospitals of level I (n = 85), II (16) and III (6), delivery rate was 30.4, 40.1 and 29.5%, and rates of pregnancy complications were 12.9, 9.8 and 21.1% (average 14.1%), with antenatal corticosteroids rate in < 37 gestational weeks being 17.3, 31.0 and 39.9% (mean 36.6%), respectively. The preterm birth rate was 0.6, 2.7 and 9.5% (mean 4.06%), and the composite rate of fetal death, stillbirth, and death immediately after delivery was 0.1, 0.4 and 0.6%, respectively. By multivariable logistic regression analysis, congenital anomalies, low Apgar scores, multi-pregnancy and amniotic fluid contamination were risk factors of adverse perinatal outcomes. Despite a higher rate of pregnancy complications than in 2010 survey, perinatal and neonatal mortality continued to fall, in particular in very preterm births. The high cesarean delivery rate in non-medically indicated cases remained a challenge.

CONCLUSIONS

Our regional birth-population data in 2015 revealed a robust and persistent improvement in the perinatal care and management of high risk pregnancies and deliveries, which should enable more studies using similar concept and protocol for vital statistics to verify the reliability and feasibility.
