Indirect effects of the Covid-19 pandemic on pregnancy
Primary sources
Ripe-tomato.org has been collecting primary scientific (click here) & newspaper reports (click here) of Covid-19 or SARS-CoV-2 infection in pregnancy since early in the pandemic (click here for our Covid-19 in pregnancy navigation page).
Here we (Jim Thornton, Keelin O’Donoghue and Kate Walker) collect primary scientific reports of the indirect effects of the pandemic on pregnancy. As usual facts but no comments. For convenience we list papers in roughly reverse order, newest first. We will update regularly.
Clarification added 1 October 2021 – We exclude studies of the effect of the pandemic on psychological scores in pregnant women, but include studies reporting effects on mental health events. Anxiety and depression scores are out. Suicide and suicide attempts are in.
