Low birth weight (LBW) remains a critical determinant of neonatal mortality and long-term metabolic syndrome, particularly in agrarian transition zones. While demographic factors are often studied, the specific impact of maternal oxygen transport capacity (hemoglobin) and somatic nutritional reserves (Mid-Upper Arm Circumference/MUAC) remains under-characterized in highland populations where the paradox of food security versus nutritional insecurity exists. A retrospective case-control study was conducted in the highland region of Bangli, Indonesia, covering all deliveries in 2024. To maximize statistical power within the available clinical population, a total sampling technique was employed for the case group (n=20 mothers delivering infants <2,500g), matched 1:2 with randomly selected controls (n=40 mothers delivering infants ≥2,500g). Data were analyzed using independent t-tests and binary logistic regression. The multivariate model was restricted to biological predictors to maintain statistical stability given the sample size. The prevalence of anemia and Chronic Energy Deficiency (CED) was significantly higher in the case group (p<0.001). Bivariate analysis indicated profound risks associated with anemia (OR=9.00) and CED (OR=6.93). In the adjusted multivariate model, maternal anemia (aOR=11.45; 95% CI: 2.50–52.40) and CED (aOR=9.80; 95% CI: 2.15–44.60) remained dominant, independent predictors. The wide confidence intervals reflect the small sample size inherent to the facility-based dataset. ROC analysis demonstrated that MUAC <23.5 cm offers excellent diagnostic accuracy (AUC=0.845). In conclusion, clinical markers of oxygen transport and nutritional substrate availability are superior predictors of LBW compared to maternal age or parity in this cohort. The findings advocate for a biological-first approach to antenatal risk stratification.

Conclusion

This study demonstrates that maternal anemia and chronic energy deficiency are dominant, independent predictors of low birth weight in the Bangli highlands.The findings suggest that the physiological competence of the mother—her oxygen transport capacity and her nutritional reserves—far outweighs the influence of traditional demographic risk factors.These results advocate for a shift in focus towards modifiable biological factors in antenatal care, emphasizing the importance of assessing and addressing anemia and CED to improve birth outcomes.

Future Research

Further research should investigate the synergistic effects of anemia and chronic energy deficiency on placental development and fetal growth, utilizing biomarkers such as serum ferritin, soluble transferrin receptors, and placental growth factor to gain a more granular understanding of the underlying mechanisms. Additionally, studies are needed to evaluate the effectiveness of targeted interventions, combining iron supplementation with high-protein nutritional support, specifically tailored to the unique physiological demands of pregnant women in highland environments. Finally, future research should explore the role of cultural and dietary factors in contributing to maternal nutritional deficiencies in this region, aiming to develop culturally sensitive and sustainable strategies to improve maternal nutrition and reduce the incidence of low birth weight.
