Impact of COVID-19 Lockdowns on Rates of Adolescent Pregnancies: A Systematic Review (preprint)

Background: Education is known to protect adolescent girls from unplanned pregnancy. School closures were component of COVID-19 “lockdown measures”. The impact of these measures on adolescent pregnancy worldwideis unknown.  Methods: We performed a systematic review to find evidence of the impact of “lockdowns” and school closures on adolescent pregnancy events during the COVID-19 pandemic. Databases including Pubmed, EMBASE, CINAHL, WHO Index Medicus, and Literatura Latinoamericana y Caribe en Ciencias de la Salud (LILACS) were searched. Studies that provided data on pregnancy rates in girls aged 10-19 before, during, and after the onset of the COVID-19 pandemic (defined as March 2020) were eligible for inclusion. Extracted data included study design, study location, age of participants, exposure period, and percentage or pregnancy rate data. Findings: On August 21st, 2023, 3049 studies were screened, with 79 eligible for full-text review. Ten studies were included in the final review: Seven performed in Africa (Uganda, Kenya, South Africa, and Ethiopia), and three in the Americas (USA and Brazil). Adolescent pregnancy increased in six out of the seven African studies while a decrease or no change was noted in USA and Brazil.All studies were at a high risk of bias. Interpretation:   Adolescent pregnancy rates during the COVID-19 pandemic may have substantially increased in sub-Saharan Africa. Data scarcity and low-quality evidence are significant limitations. The dynamic relationship between lockdown measures and adolescent pregnancies warrants ongoing multifaceted research and adaptive policies to safeguard adolescent sexual and reproductive health during health crisis. Systematic Review Registration: PROSPERO registration number CRD42022308354.

Global research priorities for COVID-19 in maternal, reproductive and child health: results of an international survey (preprint)

Background The World Health Organization's ''Coordinated Global Research Roadmap: 2019 Novel Coronavirus'' outlined the need for research that focuses on the impact of COVID-19 on pregnant women and children. More than one year after the first reported case, significant knowledge gaps remain, highlighting the need for a coordinated approach. To address this need, the Maternal, Newborn and Child Health Working Group (MNCH WG) of the COVID-19 Clinical Research Coalition conducted an international survey to identify global research priorities for COVID-19 in maternal, reproductive and child health. Method This project was undertaken using a modified Delphi method. An electronic questionnaire was disseminated to clinicians and researchers in three different languages (English, French and Spanish) via MNCH WG affiliated networks. Respondents were asked to select the five most urgent research priorities among a list of 17 identified by the MNCH WG. Analysis of questionnaire data was undertaken to identify key similarities and differences among respondents according to questionnaire language, location and specialty. Following elimination of the seven lowest ranking priorities, the questionnaire was recirculated to the original pool of respondents. Thematic analysis of final questionnaire data was undertaken by the MNCH WG from which four priority research themes emerged. Results Questionnaire 1 was completed by 225 respondents from 29 countries. Questionnaire 2 was returned by 49 respondents. The four priority research themes were 1) access to healthcare during the COVID-19 pandemic, 2) the direct and 3) indirect effects of COVID-19 on pregnant and breastfeeding women and children and 4) the transmission of COVID-19 and protection from infection. Conclusion The results of these questionnaires indicated a high level of concordance among continents and specialties regarding priority research themes. This prioritized list of research uncertainties, developed to specifically highlight the most urgent clinical needs as perceived by healthcare professionals and researchers, could help funding organizations and researchers to answer the most pressing questions for clinicians and public health professionals during the pandemic. It is hoped that these identified priority research themes can help focus the discussion regarding the allocation of limited resources to enhance COVID-19 research in MNCH globally.
