Women's experiences of maternity care in high-income countries during the pandemic health system shock
Introduction: COVID-19 disrupted healthcare systems globally, particularly challenging maternity services which continued to be operated as an essential service. Reconfigurations were implemented to continue providing care in a safe manner and in line with infection control restrictions. This systematic review of women's experiences of maternity care during the COVID-19 pandemic in high-income countries (HICs), aimed to synthesize published liter…
“Now that the baby is out, I can be vaccinated”
COVID-19 vaccines are safe and effective in pregnancy, but vaccine hesitancy limits uptake and effectiveness. This study explored COVID-19 vaccine hesitancy in pregnancy in Kilifi, coastal Kenya, to elicit reasons for vaccine hesitancy and acceptance, and to compile misconceptions around vaccination in pregnancy. Twenty-three in-depth interviews were conducted with pregnant women, mothers who had given birth in the previous 2 years and health wor…
Community engagement approaches and lessons learned
Community engagement (CE) has been recommended as an important ethical consideration for health research to enhance informed consent and exchange knowledge between researchers and community members. The purpose of this paper is to describe how CE was developed and delivered for the PRECISE prospective pregnancy cohort study in Kenya. PRECISE enrolled pregnant women in antenatal care, followed them up to the postpartum period, and collected data a…
Community perspectives on maternal dietary diversity in rural Kenya, Mozambique and The Gambia
Pregnant and lactating women in sub-Saharan Africa are vulnerable to micronutrient inadequacies, with risk of adverse pregnancy outcomes. Adequate intakes of diverse foods are associated with better micronutrient status and recommended by the World Health Organization as part of healthy eating counselling during antenatal care. However, our understanding of community knowledge of dietary diversity within the context of maternal diets is limited. …
Optimising Pre-Eclampsia Screening in Black Women; a Secondary Analysis of Data from Non-Intervention Screening Studies
Objective To compare pre-eclampsia screening strategies among Black vs. White ethnicity women. Methods Using data from prospective non-intervention cohort studies in Europe, we evaluated pre-eclampsia risk in singleton pregnancies. Risk was determined by clinical risk factor screening ('clinical'), 'clinical' with Black ethnicity as a moderate-risk factor ('clinical-modified'), and the Fetal Medicine Foundation competing-risks model at 11-13 week…
Freedom for some, but not for Mum
Introduction: Healthcare services for pregnant and postpartum ('perinatal') women were reconfigured significantly at the advent and for the duration of the SARS-CoV-2 pandemic, and despite the United Kingdom announcing 'Freedom Day' on 19 July 2021 (whereafter all legal lockdown-related restrictions were lifted), restrictions to maternity (antenatal, intrapartum, and postnatal) services remained. This study presents data from eight perinatal wome…
Postpartum recovery after severe maternal morbidity in Kilifi, Kenya
INTRODUCTION: The burden of severe maternal morbidity is highest in sub-Saharan Africa, and its relative contribution to maternal (ill) health may increase as maternal mortality continues to fall. Women's perspective of their long-term recovery following severe morbidity beyond the standard 42-day postpartum period remains largely unexplored. METHODS: This woman-centred, grounded theory study was nested within the Pregnancy Care Integrating Trans…
The Resilient Study of Post-Pandemic Maternity Care Planning
Maternity care is a core service provision of any healthcare system, delivering care for women and birthing people, and their wider family units. During the SARS-CoV-2 pandemic, much of maternity care service provision was reconfigured with the aim of continuing care provision which could not otherwise be re-scheduled or delayed, but in-line with infection control measures instituted through social and physical distancing. The RESILIENT Study was…
Sars-CoV-2 seroprevalence in pregnant women in Kilifi, Kenya from March 2020 to March 2022
Background: Seroprevalence studies are an alternative approach to estimating the extent of transmission of SARS-CoV-2 and the evolution of the pandemic in different geographical settings. We aimed to determine the SARS-CoV-2 seroprevalence from March 2020 to March 2022 in a rural and urban setting in Kilifi County, Kenya. Methods: We obtained representative random samples of stored serum from a pregnancy cohort study for the period March 2020 to …
Adverse maternal, fetal, and newborn outcomes among pregnant women with Sars-CoV-2 infection
The development and implementation of a community engagement strategy to improve maternal health in southern Mozambique
Delays to seek medical help can contribute to maternal deaths particularly in community settings at home or on the road to a health facility. Community engagement (CE) can improve care-seeking behaviours and complements community-based interventions strengthening maternal health. The purpose of this paper is to describe the process undertaken to develop and implement a large-scale community engagement strategy in rural southern Mozambique. The CE…
Changes in preterm birth and stillbirth during Covid-19 lockdowns in 26 countries
Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from −90% to +30%, were reported in many countries following early COVID-19 pandemic response measures ('lockdowns'). It is unclear whether this variation reflects real differences in lockdown impacts, or perhaps differences in stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data f…
Effects of the Covid-19 pandemic on maternal and perinatal outcomes
Economic and cost-effectiveness analysis of the Community-Level Interventions for Pre-eclampsia (CLIP) trials in India, Pakistan and Mozambique
BACKGROUND: The Community-Level Interventions for Pre-eclampsia (CLIP) trials (NCT01911494) in India, Pakistan and Mozambique (February 2014-2017) involved community engagement and task sharing with community health workers for triage and initial treatment of pregnancy hypertension. Maternal and perinatal mortality was less frequent among women who received ≥8 CLIP contacts. The aim of this analysis was to assess the incremental costs and cost-ef…

Interactions between the Physical and Social Environments with Adverse Pregnancy Events Related to Placental Disorders—A Scoping Review
More evidence is needed to determine the relationships between the environment and placental function in Africa. The results show that understanding the nature of the relationship between social determinants of health (SDH) and placental health outcomes plays a pivotal role in understanding the risk in the heterogenous communities in Africa
Guidelines for creating framework data for GIS analysis in low‐ and middle‐income countries
Key Messages While some framework data are available in LMICs, there is a lack of coordinated effort to create and share these data to support health GIS research in these settings. Manual digitizing can be used to generate framework data, and is increasingly becoming cheaper and faster due to widely available free satellite imagery and open mapping standards that allow distributed data capture. Efforts to create framework data should be done in …
