Birth weight is the first weight a fetus or baby obtains after birth.  A baby's birth weight is an indicator of future health status. Overall, an estimated 15% to 20% of all births worldwide are low birth weight, representing more than 20 million births annually. Body Mass Index before pregnancy can be considered an indicator of the mother's nutritional status, and maternal nutritional status can reduce placental-fetal blood flow and inhibit fetal growth. This study aims to determine the relationship between the body mass index of pregnant women and the birth weight of the baby. comparative research with a cross sectional approach at the Simomulyo Public Health Center. The population of this study is all mothers who gave birth to live babies in 2022. The sample for this study was taken using a total sampling of 72 people. The independent variable is the body mass index of the pregnant woman, while the dependent variable is the baby's birth weight. Data was taken from secondary data from medical records for 2022. The analysis test used Kruskall Wallis with a significance level of 0.05. Research shows that the majority of mothers who have a normal BMI give birth to 51 babies with a normal weight (70.83%), mothers with a thin BMI give birth to babies with a low birth weight as many as 4 (5.56%), mothers with a high BMI give birth to normal babies. 15 people (20.83%) and mothers with obese BMI gave birth to 1 normal baby (1.39%) and 1 large baby (1.39%). The results of the analysis using Kruskall Wallis obtained a value of p = 0.000 (p < 0.05). There is a relationship between the body mass index of pregnant women and the birth weight of the baby.
