What may happen if you are pregnant during COVID-19 lockdown? Aretrospective study about peripartum outcomes

BACKGROUND: One of the provisions implemented to contain the spread of COVID-19 infections in Italy was the lockdown. Effects of the lockdown on childbirth outcomes and on the well-being of both the mother and the child have not yet been defined. An inadequate diet during pregnancy and a reduced physical activity can predispose women to become overweight or obese and trigger the development of various complications and maternal-fetal adverse outcomes. METHODS: This is a retrospective study including all consecutive patients who delivered at the Maggiore della Carità Hospital in Novara, Italy, in April-May 2017 (group 1, N.=294), a period prior to the pandemic, and during the same months in 2020 (group 2, N.=256) during and immediately after lockdown. Clinical data were extracted from the report "Childbirth Assistance Certificate (CedAP) - Birth Event Analysis." RESULTS: Demographic characteristics were similar between the two study groups, except for a decreased number of married couples in group 2 (P=0.018) and an increased percentage of patients with clinical checkups at family planning facilities in 2020 (P=0.04). The number of hospitalizations during pregnancy was 26 (8.9%) vs. 10 (3.9%) with a significative reduction during 2020 (P=0.004). Regarding obstetric outcomes, we observed a significant increase in induction of labour in 2020 (23.9% vs. 35.9%; P=0. 002), a reduction of amniorrhexis (11.3% vs. 5.5% P=0.015), a reduction of supine positions with an increase of vertical and all four positions in 2020 (49.3% vs. 61.9% and 9.5% vs. 12.4% respectively, P=0.023), and a reduction of left occipito-anterior presented part (63.2% vs. 55.4%) in favor of right occipito-anterior (34.7% vs. 41.2%, P=0.019). CONCLUSIONS: There were no significant differences either for antepartum or intrapartum complications. Long-term studies are needed to evaluate psychological, behavioral, and epigenetic effects of maternal physical inactivity on obstetric outcomes.
