Abstract

Maternal smoking increases the risk of spontaneous abortion. Polymorphic N-acetyltransferase (NAT2) and glutathione S-transferase (GSTM1) affect metabolism of some mutagens found in tobacco smoke. Genotypes and smoking were studied in women with at least two spontaneous abortions (N = 32) and those with at least two livebirths (N = 179). Smoking slightly increased risk (odds ratio = 1.3; 95% confidence interval = 0.6-2.9), but NAT2 and GSTM1 did not. NAT2 or GSTM1 polymorphisms did not appreciably modify smoking-related risk.
