Examining Fetal Growth Biometrics and Last Menstrual Period Correlation in Minangkabau Ethnicity during Third Trimester Ultrasound

Abstract

Background Fetal growth significantly impacts well-being and health outcomes at birth, exerting a profound influence on the occurrence of perinatal complications and mortality rates. Aim This study aims to establish normal fetal growth data based on biometric variations in the Minangkabau ethnic group. Methods An analytical cross-sectional study focusing on pregnant women who underwent pregnancy check-ups was conducted in December 2020. Results A total of 520 pregnant women had third trimester ultrasounds. Most were aged 21-39 with one parity, had a senior high school education, and were unemployed. The strongest correlation (R=0.86) was between the last menstrual period (LMP) and biparietal diameter (BPD), while the weakest (R=0.79) was between LMP and head length (HL). All variables were highly significant (p<0.05). Conclusions Fetal growth biometrics (BPD, FL, HC, AC, and HL) were associated with LMP of third trimester ultrasound pregnancy on Minangkabau ethnic.
