Persistent postpartum depressive symptoms and developmental impairment in Bangladeshi children
Background: Optimal child development across cognitive, language, and motor domains is essential for long-term health and well-being. Postpartum depression has been linked to adverse child developmental outcomes, but evidence on the impact of persistent postpartum depressive symptoms (PPDS) across these domains and over time remains limited, particularly in low- and middle-income countries. Methods: We retrieved data from the Alliance for Materna…
Prevalence and risk factors for anaemia during pregnancy in Sylhet district of Bangladesh
Background: Anaemia during pregnancy poses a major public health problem globally, with reported prevalences ranging from approximately 5.2% to 65.7%. A significant portion of this burden is borne by low- and middle-income countries. We aimed to determine the prevalence of anaemia during pregnancy and identify the factors associated with anaemia in the third trimester of pregnancy in a cohort of women in the rural Sylhet district, Bangladesh. Met…
Setting research priorities for global pandemic preparedness
Background: In this priority-setting exercise, we sought to identify leading research priorities needed for strengthening future pandemic preparedness and response across countries. Methods: The International Society of Global Health (ISoGH) used the Child Health and Nutrition Research Initiative (CHNRI) method to identify research priorities for future pandemic preparedness. Eighty experts in global health, translational and clinical research id…
Prevalence and risk factors of Severe Acute Respiratory Syndrome Coronavirus 2 infection in women and children in peri-urban communities in Pakistan
Background: Population-based seroepidemiological surveys provide accurate estimates of disease burden. We compare the COVID-19 prevalence estimates from two serial serological surveys and the associated risk factors among women and children in a peri-urban area of Karachi, Pakistan. Methods: The AMANHI-COVID-19 study enrolled women and children between November 2020 and March 2021. Blood samples were collected from March to June 2021 (baseline) a…
Research priorities to reduce the impact of Covid-19 in low- and middle-income countries
Background: The COVID-19 pandemic has caused disruptions to the functioning of societies and their health systems. Prior to the pandemic, health systems in low- and middle-income countries (LMIC) were particularly stretched and vulnerable. The International Society of Global Health (ISoGH) sought to systematically identify priorities for health research that would have the potential to reduce the impact of the COVID-19 pandemic in LMICs. Methods:…
Sero-prevalence and risk factors for Severe Acute Respiratory Syndrome Coronavirus 2 infection in women and children in a rural district of Bangladesh
Background: Bangladesh reported its first COVID-19 case on March 8, 2020. Despite lockdowns and promoting behavioural interventions, as of December 31, 2021, Bangladesh reported 1.5 million confirmed cases and 27 904 COVID-19-related deaths. To understand the course of the pandemic and identify risk factors for SARs-Cov-2 infection, we conducted a cohort study from November 2020 to December 2021 in rural Bangladesh. Methods: After obtaining infor…
Machine learning prediction of gestational age from metabolic screening markers resistant to ambient temperature transportation
Background: Knowledge of gestational age is critical for guiding preterm neonatal care. In the last decade, metabolic gestational dating approaches emerged in response to a global health need; because in most of the developing world, accurate antenatal gestational age estimates are not feasible. These methods initially developed in North America have now been externally validated in two studies in developing countries, however, require shipment o…
Using Amanhi-ACT cohorts for external validation of Iowa new-born metabolic profiles based models for postnatal gestational age estimation
BACKGROUND: Globally, 15 million infants are born preterm and another 23.2 million infants are born small for gestational age (SGA). Determining burden of preterm and SGA births, is essential for effective planning, modification of health policies and targeting interventions for reducing these outcomes for which accurate estimation of gestational age (GA) is crucial. Early pregnancy ultrasound measurements, last menstrual period and post-natal ne…
Research priorities for adolescent health in low- and middle-income countries
BACKGROUND: In order to clarify priorities and stimulate research in adolescent health in low- and middle-income countries (LMICs), the World Health Organization (WHO) conducted two priority-setting exercises based on the Child Health and Nutrition Research Initiative (CHNRI) methodology related to 1) adolescent sexual and reproductive health and 2) eight areas of adolescent health including communicable diseases prevention and management, injuri…
Understanding biological mechanisms underlying adverse birth outcomes in developing countries
OBJECTIVES: The AMANHI study aims to seek for biomarkers as predictors of important pregnancy-related outcomes, and establish a biobank in developing countries for future research as new methods and technologies become available. METHODS: AMANHI is using harmonised protocols to enrol 3000 women in early pregnancies (8-19 weeks of gestation) for population-based follow-up in pregnancy up to 42 days postpartum in Bangladesh, Pakistan and Tanzania, …
Setting health research priorities using the CHNRI method
BACKGROUND: Several recent reviews of the methods used to set research priorities have identified the CHNRI method (acronym derived from the "Child Health and Nutrition Research Initiative") as an approach that clearly became popular and widely used over the past decade. In this paper we review the first 50 examples of application of the CHNRI method, published between 2007 and 2016, and summarize the most important messages that emerged from tho…
Development and validation of a simplified algorithm for neonatal gestational age assessment – protocol for the Alliance for Maternal Newborn Health Improvement (Amanhi) prospective cohort study
OBJECTIVE: The objective of the Alliance for Maternal and Newborn Health Improvement (AMANHI) gestational age study is to develop and validate a programmatically feasible and simple approach to accurately assess gestational age of babies after they are born. The study will provide accurate, population-based rates of preterm birth in different settings and quantify the risks of neonatal mortality and morbidity by gestational age and birth weight i…
Approaches, tools and methods used for setting priorities in health research in the 21st century
BACKGROUND: Health research is difficult to prioritize, because the number of possible competing ideas for research is large, the outcome of research is inherently uncertain, and the impact of research is difficult to predict and measure. A systematic and transparent process to assist policy makers and research funding agencies in making investment decisions is a permanent need. METHODS: To obtain a better understanding of the landscape of approa…
Setting health research priorities using the CHNRI method
etting health research priorities is a complex and value-driven process. The introduction of the Child Health and Nutrition Research Initiative (CHNRI) method has made the process of setting research priorities more transparent and inclusive, but much of the process remains in the hands of funders and researchers, as described in the previous two papers in this series However, the value systems of numerous other important stakeholders, particular…
Setting health research priorities using the CHNRI method
INTRODUCTION: Crowdsourcing has become an increasingly important tool to address many problems - from government elections in democracies, stock market prices, to modern online tools such as TripAdvisor or Internet Movie Database (IMDB). The CHNRI method (the acronym for the Child Health and Nutrition Research Initiative) for setting health research priorities has crowdsourcing as the major component, which it uses to generate, assess and priorit…

Setting health research priorities using the CHNRI method
Large groups of researchers who agree to offer their research ideas and then score them against pre–defined criteria are at the heart of each CHNRI priority–setting exercise. Although the roles of funders and other stakeholders are also very important, much of the exercise is focused on selecting and engaging a large group of researchers, obtaining their input and analysing it to derive the initial results of the process. In a sense, a CHNRI exer…
Setting health research priorities using the CHNRI method
In 2007 and 2008, the World Health Organization's Department for Child and Adolescent Health and Development commissioned five large research priority setting exercises using the CHNRI (Child Health and Nutrition Research Initiative) method. The aim was to define research priorities related to the five major causes of child deaths for the period up to the year 2015. The selected causes were childhood pneumonia, diarrhoea, birth asphyxia, neonatal…
