Abstract

OBJECTIVE:

To identify predictors and outcomes associated with a birth weight of 4000g or more in Lusaka, Zambia.

METHODS:

Data from women who delivered between February 2006 and August 2011 were obtained from electronic perinatal records at 25 public sector facilities in Lusaka. Macrosomia was defined as a birth weight of 4000g or more and normal birth weight as 2500-3999g. Maternal and newborn characteristics were analyzed for association with macrosomia.

RESULTS:

There were 4717 macrosomic and 187 117 normal birth weight newborns. The strongest predictors of macrosomia were high BMI (adjusted odds ratio [AOR], 2.88; 95% confidence interval [CI], 1.95-4.24), prior macrosomic newborn (AOR, 7.60; 95% CI, 6.81-8.49), and history of diabetes (AOR, 3.09; 95% CI, 1.36-6.98). Macrosomic newborns were at increased risk for cesarean delivery (AOR, 1.63; 95% CI, 1.35-1.96), fresh stillbirth (AOR, 2.24; 95% CI, 1.56-3.21), Apgar score of under 7 at 5minutes (AOR, 2.03; 95% CI, 1.33-3.11), and neonatal intensive care admission (AOR, 2.07; 95% CI, 1.32-3.23).

CONCLUSION:

Screening for macrosomia should be considered for high-risk patients in Sub-Saharan Africa. Institutional delivery at facilities with operating rooms and neonatal intensive care services should be encouraged.
