OBJECTIVE: To investigate whether a relationship between birth weight (BW) and amniotic fluid index (AFI) existed for term @entity1 with intact membranes and, if so, whether it could predict @entity8455 and @entity1592 . STUDY DESIGN: Two hundred thirty-one eligible @entity1 at term (37-42 weeks' gestation) had an AFI between 5.0 and 24.0 cm at the time of admission. Demographic information was collected, including BW. Statistical comparisons were made, with significance set at P < .05. RESULTS: The mean gestational age was 39.5 weeks, and the mean AFI was 11.3. There were 28 @entity1 with BWs > 4,000 g ( @entity8455 ). The cesarean section rate was 16.9%. @entity8455 was associated with a higher cesarean section rate (39.2% vs. 13.8%, P < .002). The mean AFI was higher for those with @entity8455 (13.5 vs. 11.0, P < .001). @entity1 with an AFI > 15.0 had over twice the incidence of @entity8455 (RR 2.72, 1.1-6.6, 32.1% vs. 14.8%, P < .027). The risk was even greater for them with an AFI > 18.0 (RR 6.4, 2.2-18.7, P < .002). A linear relationship was observed between AFI and BW (r2 .061, P < .0001). BW increased with increasing AFI. No relationship between AFI of 5-8 and BW < 2,500 g was found. CONCLUSION: Increasing AFI correlates linearly with increasing BW, and @entity8455 is associated with an increased incidence of cesarean delivery. AFI > 15 carries over double the risk of birth of a macrosomic @entity1 , while AFI > 18 has a risk of over six times. No association between low normal AFI and a growth-restricted @entity1 was found.
