The effect of the Covid pandemic and lockdown on stillbirth rates in a South Indian perinatal centre

Abstract Objectives The Covid-19 pandemic affected antenatal care in many parts of the world. It brought about many changes as part of control and containment measures. We examined the effect of the first and second waves of the pandemic in India on stillbirth rates, as indicators of quality of maternity care. Methods Observational study at a tertiary referral perinatal centre with approximately 10,000 births annually. The Covid-19 first wave period was taken as January to December 2020 with lockdown March to June 2020, which included complete shut down of clinics and ultrasound services. The second wave was from January to September 2021. All women with singleton pregnancy who had hospital based antenatal care were included. We investigated monthly trends in obstetric load (new antenatal registrations, total obstetric clinic numbers and total births) with stillbirth numbers as the pandemic continued (daily Covid case trend). We compared first and second wave stillbirth rates, overall as well as those that were small for gestational age (<10th centile) at delivery. Results There were 9,251 births with 32 stillbirths in the first wave (rate 3.46/1,000) and 6,228 births with 14 stillbirths in the second wave (2.25/1,000). This represented a 54% higher rate in the first phase and extended lockdown period (p=0.08). The incidence of stillbirths that were SGA was significantly higher in the first wave: 14 vs. 2, (p=0.03). Conclusions Reduced access to planned antenatal care during Covid-19 pandemic lockdown was associated with a significant increase in SGA stillbirths.
