Centre of Excellence in Women and Child Health

Preterm birth is the leading cause of infant death worldwide, but the causes of preterm birth are largely unknown. During the early COVID-19 lockdowns, dramatic reductions in preterm birth were reported; however, these trends may be offset by increases in stillbirth rates. It is important to study these trends globally as the pandemic continues, and to understand the underlying cause(s). Lockdowns have dramatically impacted maternal workload, access to healthcare, hygiene practices, and air pollution - all of which could impact perinatal outcomes and might affect pregnant women differently in different regions of the world. In the international Perinatal Outcomes in …

Achieving Accurate Estimates Of Fetal Gestational Age And Personalised Predictions Of Fetal Growth Based On Data From An International Prospective Cohort Study: A Population-Based Machine Learning Study, Russell Fung, Jose Villar, Ali Dashti, Leila Cheikh Ismail, Eleonora Staines-Uria, Eric O. Ohuma, Maria Carvalho, Shama Munim, Zulfiqar Ahmed Bhutta, International Fetal And Newborn Growth Consortium For The 21st Century (Intergrowth-21st)

Department of Obstetrics & Gynaecology

Background: Preterm birth is a major global health challenge, the leading cause of death in children under 5 years of age, and a key measure of a population's general health and nutritional status. Current clinical methods of estimating fetal gestational age are often inaccurate. For example, between 20 and 30 weeks of gestation, the width of the 95% prediction interval around the actual gestational age is estimated to be 18-36 days, even when the best ultrasound estimates are used. The aims of this study are to improve estimates of fetal gestational age and provide personalised predictions of future growth.

Yim, Pauline Samia, Christopher Naugler, Nicole Letourneau, The Maternal Infant Global Health Team (Might) Collaborators In Research

Paediatrics and Child Health, East Africa

Background: Adverse childhood experiences (ACEs) are associated with prenatal mental health and negative pregnancy outcomes in high income countries, but whether the same association exists in Pakistan, a low- to middle-income (LMI) country, remains unclear.

Methods: Secondary data analyses of a prospective longitudinal cohort study examining biopsychosocial measures of 300 pregnant women at four sites in Karachi, Pakistan. A predictive multiple logistic regression model for preterm birth (PTB; i.e., <37 weeks’ gestation) was developed from variables significantly (P < 0.05) or marginally (P < 0.10) associated with PTB in the bivariate analyses.

Results: Of the 300 women, 263 (88%) returned for delivery and were included in the current analyses. The PTB rate was 11.1%. We found no association between ACE and PTB. Mother's …

Background: Preterm birth (PTB) remains the leading cause of neonatal mortality and long term disability throughout the world. Though complex in its origins, a growing body of evidence suggests that first trimester administration of low dose aspirin (LDA) may substantially reduce the rate of PTB.
Methods: Hypothesis: LDA initiated in the first trimester reduces the risk of preterm birth. Study Design Type: Prospective randomized, placebo-controlled, double-blinded multi-national clinical trial conducted in seven low and middle income countries. Trial will be individually randomized with one-to-one ratio (intervention/control) Population: Nulliparous women between the ages of 14 and 40, with a …

Antenatal Umbilical Coiling Index And Newborn Outcomes: Cohort Study, Josephine Mwikali Ndolo, Sudhir Vinayak, Micah Ominde, William Stones

Imaging & Diagnostic Radiology, East Africa

Objectives: We aimed to test the predictive value of antenatal umbilical coiling index (aUCI) among a prospectively recruited cohort of antenatal women.

Methods: Women with singleton pregnancies were recruited at their second‑trimester scan. Images of the umbilical cord were used to calculate the aUCI. Pregnancy and birth outcomes were recorded and statistical associations between aUCI and small for gestational age (SGA) using international standard birth weight centiles and preterm birth were investigated (n = 430).

Results: aUCI results were consistent with the literature and showed good reproducibility between observers. Abnormal aUCI was not associated with SGA, but there was a …

Obstetrics and Gynaecology, East Africa

The scientific basis for antenatal corticosteroids (ACS) for women at risk of preterm birth has rapidly changed in recent years. Two landmark trials—the Antenatal Corticosteroid Trial and the Antenatal Late Preterm Steroids Trial—have challenged the long-held assumptions on the comparative health benefits and harms regarding the use of ACS for preterm birth across all levels of care and contexts, including resource-limited settings. Researchers, clinicians, programme managers, policymakers and donors working in low-income and middle-income countries now face challenging questions of whether, where and how ACS can be used to optimise outcomes for both women and preterm newborns.

Community Health Sciences

BACKGROUND:

Antenatal corticosteroids (ACS) for women at high risk of preterm birth is an effective intervention to reduce neonatal mortality among preterm babies delivered in hospital settings, but has not been widely used in low-middle resource settings. We sought to assess the rates of ACS use at all levels of health care in low and middle income countries (LMIC).

METHODS:

We assessed rates of ACS in 7 sites in 6 LMIC participating in the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Global Network for Women and Children's Health Research Antenatal Corticosteroids Trial (ACT), a cluster-randomized trial …

Community Health Sciences

BACKGROUND:

The Antenatal Corticosteroid Trial assessed the feasibility, effectiveness, and safety of a multifaceted intervention to increase the use of antenatal corticosteroids (ACS) in mothers at risk of preterm birth at all levels of care in low and middle-income countries. The intervention effectively increased the use of ACS but was associated with an overall increase in neonatal deaths. We aimed to explore plausible pathways through which this intervention increased neonatal mortality.

METHODS:

We conducted a series of secondary analyses to assess whether ACS or other components of the multifaceted intervention that might have affected the quality of care contributed to …

Community Health Sciences

BACKGROUND:

The Antenatal Corticosteroid Trial (ACT) assessed the feasibility, effectiveness, and safety of a multifaceted intervention to increase the use of antenatal corticosteroids (ACS) in mothers at risk of preterm birth at all levels of care in low and middle-income countries. The intervention effectively increased the use of ACS but had no overall impact on neonatal mortality in the targeted <5(th) percentile birth weight infants. Being in the intervention clusters was also associated with an overall increase in neonatal deaths. We sought to explore plausible pathways through which this intervention increased neonatal mortality.

METHODS:

We conducted secondary analyses to assess site differences in outcome and potential explanations for the differences in outcomes if found. By site, and in the intervention and control clusters, we evaluated characteristics of the mothers and care systems, the …

The Association Between Parity, Infant Gender, Higher Level Of Paternal Education And Preterm Birth In Pakistan: A Cohort Study, Kiran Shaikh, Shahirose Sadrudin Premji, Marianne S. Rose, Ambreen Kazi, Shaneela Khowaja, Suzanne Tough

School of Nursing & Midwifery

Background:

High rates of antenatal depression and preterm birth have been reported in Pakistan. Self reported maternal stress and depression have been associated with preterm birth, however findings are inconsistent. Cortisol is a biological marker of stress and depression, and its measurement may assist in understanding the influence of self reported maternal stress and depression on preterm birth.

Methods:

In a prospective cohort study pregnant women between 28 to 30 weeks of gestation from the Aga Khan Hospital for Women and Children completed the A-Z Stress Scale and the Centre for Epidemiology Studies Depression Scale to assess stress and depression …
