Abstract: Introduction: Pregnancy at an early age causes nutritional competition between mother and fetus, which has a negative impact on the health of the mother and fetus, and inhibits growth in infancy. The purpose of this study was to determine the effect of nutritional status of young pregnant women and the health of newborns on the growth of children aged 6-24 months. Material and Methods: A sample of 100 mothers and children based on inclusion criteria. Primary and secondary data collection was carried out from April to June 2020 after obtaining ethical permission. The analysis method uses Partial Least Square with the smart PLS 3.0 application. Result: The R2 values generated for the variables of child growth and newborn health were 0.074 and 0.055. The nutritional status of pregnant women at early age significantly affects the health of newborns (T-statistic above the rule of thumb, namely 3.024). Furthermore, the health of the newborn significantly affects the growth of the child (the T-statistic is above the rule of thumb, namely 2.136). The nutritional status of pregnant women at early age had an impact but did not significantly affect the growth of the child (T-statistic under the rule of thumb, namely 0.124). Conclusion: Prevention of pregnancy at an early age is important because it affects the growth of children aged 6-24 months and is a risk factor for growth problems from generation to generation.
