Abstract
Introduction: The objective of this study was to determine the impact of the stage-based classification of fetal growth restriction (FGR) on the magnitude of FGR, preterm births (PTBs), and birthweight (BW) in a rural population of Madhya Pradesh in Central India. Methods: The program covered 168 public sector centers for pregnant women and infants that provided services to nearly 220,000 people. The third-trimester assessments included fetal biometry, growth and environment assessments, and Doppler assessments. Fetal growth was staged using the Barcelona protocol as stages 1–4 FGR, small for gestational age, and no FGR. The data from the last ultrasound assessment before childbirth were considered. Regular training programs covering preconception care, antenatal and postnatal care were organized in the local language for the public sector community health workers of the program district. Childbirth outcomes were collected from the obstetric service of the local public sector hospital. Results: The analysis included 1,229 pregnancies from 2019 to 2023. The overall magnitude of FGR using estimated fetal weight <10th centile was 19.61% and reduced to 13.34% with the stage-based classification. The magnitude of FGR using the stage-based classification reduced from 27.59% in 2019 to 8.95% in 2023. The PTB in the stage-based FGR subgroup declined from 35.0% in 2019 to 3.45% in 2023 and 96.55% of the stage 1 FGR babies in 2023 were delivered at term. The overall mean BW in the program area improved from 2,772.41 (357.11) g in 2019 to 2,819.68 (377.31) g in 2023. The perinatal mortality rate (8.95 per 1,000 pregnancies) in the program area for 2019–2023 was much lower than the 31.9 per 1,000 pregnancies reported for Madhya Pradesh. Conclusion: The change to a stage-based classification of FGR integrated with low-dose aspirin and fetal Doppler studies reduced the incidence of FGR and PTB and perinatal mortality and increased BW in this rural community.
