Correlation of Fetal Growth Between Last Menstrual Period and third Trimester Ultrasound Pregnancy on Ethnic Minangkabau

Abstract

BACKGROUND: Fetal growth is a vital thing that determines the quality of life at birth. Because the multinational studies available today represent a very limited choice of a varied world population.
 AIM: this study is expected to provide results in the form of more parameters. accurate in determining fetal growth estimates.
 MATERIAL AND METHODS: This study is an analytical study using a cross sectional approach determine fetal growth biometry in the Minangkabau ethnic group. The selected sample was pregnant women who came to check their pregnancy in December 2020 at Fetomaternal clinic Hospital M. Djamil Padang and Network Hospital in the Department of Obstetrics and Gynecology Faculty of Medicine Andalas University. Bivariate analysis using Pearson correlation test because the data distribution was normally distributed with P value <0,05 and then multivariate analysis using linear regression.
 RESULTS: Five hundred and twenty pregnant women who came to check at 3rd trimester (28-40 weeks by US). The characteristics of the research subjects were the average age of pregnant women ranging from 21-39 years with the average was 28.49 ± 4.5 years, parity 1 as many as 203 people (46,7%), and the average level of education at senior high school as many as 431 people (82,9%), and there were 123 working pregnant women (42,5%). Based on the Pearson analysis, Correlation between of each variable BPD, HC, AC, FL, and HL to LMP, there is the strongest correlation between LMP and AC, which is r = 0,799 and the weakest correlation between LMP and HL is r = 0,162, for all variables is very significant (p value 0,000). The multivariate analysis with linear regression, there is a significant value that the simultaneous measurement of biometric variables (BPD, HC, AC, FL, HL) on the LMP would be 84.6% more significant.
 CONCLUSIONS: There is a significant correlation fetal growth between LMP and 3rd trimester ultrasound pregnancy with variable BPD, HC, AC, FL, HL on minangkabau ethnic
