SUBSTANCE ABUSE RAISES RISK FOR GASTROSCHISIS
Reduced blood supply to the developing abdominal wall is thought to cause gastroschisis, a life-threatening condition where the intestines protrude from a hole near the umbilical cord.
|Using recreational drugs before or early
in pregnancy increased the risk for gastroschisis. A higher risk was seen if the mother uses more than one type of drug, and if both parents are drug users.
|Cocaine-using mothers were more than 4 times as likely to have a baby with gastroschisis.|
|Using marijuana, amphetamines, or alcohol (either daily or binge drinking) raised risk by 2 to 4 times.|
DRUGS DID NOT RAISE NEURAL TUBE DEFECT RISK
|Using cocaine, amphetamines/speed or marijuana before conception or in early pregnancy was associated with reduced risk for neural tube defects.|
|This may be due to reporting differences (mothers of affected infants may be reluctant to admit to drug use), higher miscarriage rate among drug-exposed pregnancies or some other bias.|
|Father’s drug use didn’t increase risk.|
