Determinants of macrosomia among newborns delivered in Jigjiga City, Eastern Ethiopia: a case-control study

Abstract

Abstract Background Macrosomia is a forgotten health problem that directly or indirectly affects maternal and neonatal health outcomes. There is a lack of evidence on the factors that affect macrosomia in eastern Ethiopia. This study aimed to assess the determinants of macrosomia among newborns delivered in Jigjiga City, Eastern Ethiopia. Methods An institutional-based case-control study was conducted among 82 cases and 164 controls in Jigjiga City from June 25 to August 24, 2023. Bivariable and multivariable logistic regression were used to identify the determinants of macrosomia. An adjusted odds ratio (AOR) with a 95% confidence interval was used to report the strength of the association, and the statistical significance was declared at a p-value < 0.05. Results This study found that lack of preconception care (AOR = 2.48, 95% CI: 1.29, 4.76); post-term pregnancy (AOR = 2.90, 95% CI: 1.16, 7.28); inadequate physical activity (AOR = 3.52, 95% CI: 1.55, 7.98), having previous macrosomia (AOR = 4.52, 95% CI: 2.18, 9.36), and gestational diabetic mellitus (AOR = 2.58, 95% CI: 1.10, 6.28) were the main risk factors of macrosomia. Conclusion This study indicated that failed utilization of preconception care, inadequate physical activity during pregnancy, post-term pregnancy, gestational diabetic mellitus, and having previous macrosomia were the risk factors for fetal macrosomia. Encouraging women to utilize reproductive health services and providing special care for high-risk mothers are essential to reducing and preventing the level of fetal macrosomia and its consequences.
