INCREASED RISK OF SPASTIC DIPLEGIA AMONG VERY-LOW-BIRTH-WEIGHT CHILDREN AFTER PRETERM LABOR OR PRELABOR RUPTURE OF MEMBRANES

Our objective was to study the association of spastic diplegia (SDP; N = 29) with the initiator of preterm birth in a regional cohort of 312 6-year-old very low birth weight children (less than or equal to 1500 gm). We determined the prevalence of SDP among those children born af ter idiopathic preterm onset of labor (POOL) or prelabor rupture of me mbranes (PROM) (12% SDP), and among those born after pregnancy-induced hypertension or other medical indications for preterm delivery (4% SD P). Stratification showed that 83% of the children with diplegia were born after POOL or PROM. The threefold increased risk of SDP among tho se children born after POOL or PROM compared with the remainder of the cohort (crude odds ratio 3.2, 95% confidence interval 1.2 to 8.5) rem ained elevated after controlling for perinatal and neonatal variables (odds ratio 2.4 to 2.7) in logistic regression models. We conclude tha t birth after POOL of PROM increases the risk of SDP among very low bi rth weight children and speculate that this might be related to infect ious processes leading to both POOL or PROM and SDP.
