Women with both a DHFR deletion allele and low folate intake ( < 400 microg/d from diet plus supplements ) had a significantly greater risk of preterm delivery ( AOR : 5.5 ; 95 % CI : 1.5 , 20.4 ; P = 0.01 ) and a significantly greater risk of having an infant with a low birth weight ( AOR : 8.3 ; 95 % CI : 1.8 , 38.6 ; P = 0.01 ) than did women without a deletion allele and with a folate intake > /=400 microg/d .
