Neonatal and Maternal Outcome of COVID-19 positive women in Sri Lanka: Secondary Analysis using National COVID-19 Positive Pregnant Women Surveillance
Abstract
Objectives
This study aims to describe the population level data on neonatal and maternal outcomes of COVID-19 positive pregnant women of Sri Lanka by secondary analysis using National COVID-19 Positive Pregnant Women Surveillance.
Design
Secondary analysis of surveillance data from the National COVID-19 positive pregnant women surveillance, Sri Lanka. Data of all pregnant women whose maternal and neonatal outcomes were reported in National Surveillance from 1st March 2020 to 31st October 2021 were included in the study. Associated factors for maternal and neonatal outcomes, namely POA at delivery, mode of delivery, birthweight, immediate place of newborn care, congenital abnormalities, and condition of neonate at completion of one month were calculated using univariate and multivariate Odds ratios.
Results
Maternal COVID-19 infection reported preterm birth rate of 11.9%, LSCS rate of 54.5%, low birthweight rate16.5% and 8.3% of the newborns requiring intensive care. Neonatal mortality rate was 9 per 1000 live births. Pre-pregnancy overweight and obesity increased the risk of preterm delivery compared to pregnant women with normal BMI by 46.7% (AOR=1.467, CI=1.111-1.938, P=0.007). In contrast, the risk of preterm delivery reduced by 82.4% (AOR=0.176, CI=0.097-0.317, p<0.001) and presence of any type of congenital abnormalities in newborns by 72.4% among the COVID-19 positive women who required only inward treatment in comparison to women with severe COVID-19 infection requiring intensive care (AOR=0.276, CI=0.112-0.683, p=0.005).
Conclusion
Increased severity of maternal COVID-19 infection and pre-pregnancy overweight/ obesity were associated with many adverse pregnancy and neonatal outcomes. Therefore, close observation and aggressive management of COVID-19 among the pregnant women should be considered to reduce the risk of progressing to severe illness.
