Twenty-eight patients who delivered neonates small for gestational age (SGA) were followed through 32 subsequent pregnancies of 28 weeks or longer. Subsequent SGA infants were born in 28% of cases. Chances of another SGA birth were especially high in patients who had severe preeclampsia, who had chronic hypertension, or who were drug abusers. When there was no obvious cause in the first pregnancy, a second SGA infant was born in 25% of cases in an unpredictable manner, unrelated to the severity of growth compromise in the previous pregnancy.
