Abstract : The height of prenatal is a risk factor for the Length of newborn infants. Other risks that may affect the Length of a newborn infant are the Body Mass Index (BMI), the age of prenatal during their early pregnancy, the low intake of energy and protein, and the history of chronic energy deficiency. The goal of the research is to determine the various factors related to the Length of newborn infants. The results were expected to provide the determinants of newborn infant length, which can be predicted before pregnancy until the date of labor. The result can be used as a basis to determine the appropriate intervention in the prevention of stunted children. The study design is cross-sectional, with a total sample of 46 prenatal. The Spearman correlation test showed that only three variables could be included in the prediction models with p < 0.25. It was the height of mothers before pregnancy (RS = -0,027; p=0,060), the energy intake of pregnant women with in the last month pregnancy (RS: 0,553; p=0,00), and protein intake of pregnant women with in the last month of pregnancy (RS=0,42; p=0,002). Prediction model produces in Multiple Linear Regression Line Equation is the length of newborn infant = 57.268 - Protein intake 0,075x average - 0.079 x height before pregnancy + 0.002 x intake of energy last one month + 0.090 x intake Protein 1 last month. It is recommended that pregnant women with short stature need more energy intake during pregnancy, especially in the last month of pr
