A woman's nutritional status significantly impacts the qualities of the baby she delivers, as assessed by the baby's weight and length at birth. This study aimed to identify factors influencing birth weight and length using a retrospective case-control design with secondary data collected from the mothers' cohort register at the Community Health Center in 2020-2021. The study included 100 samples, comprising 25 cases and 75 controls. Several determinants of birth weight and length were examined: the mother's age (OR=4.1, 95% CI 1.41-12.0), weight gain during pregnancy (OR=3.6, 95% CI 1.051-12.553), mid-upper arm circumference (OR=2.9, 95% CI 1.061-8.220), hemoglobin level (OR=4.711, 95% CI 1.57-14.11), and iron supplement intake (OR=1.837, 95% CI 0.600-5.624), with hemoglobin level identified as the most influential factor on birth qualities. Mothers with less than normal hemoglobin levels have a 4.7 times higher risk of delivering babies of lower weight and length than mothers with normal hemoglobin levels. The impact of low hemoglobin in pregnant women includes reduced oxygen supply for both the mother and fetus, resulting in low birth weight, child anemia, premature birth, and child mortality. Given these significant effects, it is crucial to establish standards for health services in Indonesia, ensuring that pregnant women with low hemoglobin receive comprehensive care aligned with Indonesia's Sustainable Development Goals (SDGs) standards.
