Risk factors for term or near-term fetal growth restriction in the absence of maternal complications

Abstract

The objective of this study was to examine risk factors for term or near-term fetal growth restriction (FGR) in the absence of pregnancy complications. We completed a survey of uncomplicated single live births delivered in Greater Beirut, Lebanon. FGR cases were defined as below the 10th percentile of expected weight at gestational age. Multivariate logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CIs). Main predictors of FGR were female gender (OR, 1.94; 95% CI, 1.46 to 2.59), nulliparity (Or, 1.66; 95% CI, 1.25 ton 2.20), low prepregnancy weight (OR, 2.52; 95% CI, 1.58 to 4.01), short stature (OR, 2.59; 95% CI, 1.57 to 4.28), and low pregnancy weight gain (OR, 1.75; 95% CI, 1.21 to 2.55). Anthropometric characteristics of mothers are important modifiable determinants of fetal size in our developing urban population of uncomplicated births.
