This study employed the master table as a data collection method. The data analysis used is the chi-square test. Results: Based on the results of chi-square analysis, maternal parity (p-value = 0.228) with OR = 1.518, gestational age (0.000) OR = 15.200, multiple pregnancies (0.009) and OR = 10.161, and preeclampsia (0.164) and OR = 0.571. Conclusion: There is a significant relationship between gestational age and multiple pregnancies with the incidence of LBW. Meanwhile, parity and preeclampsia do not have a significant relationship with the incidence of LBW. It is recommended for every pregnant woman to carry out routine check-ups during pregnancy to prevent the occurrence of LB
