Information data about sex, type of delivery, maternal diseases, placenta problems, uterine abnormality, previous history of abortion and infertility in mothers, maternal addiction, duration of previous pregnancy in mother and prental care were filled in questionaire. We observed in our case group, previous maternal systemic disease (hypertension, ecclampsia, infection disease) 5.2 time, previous abortion and infertility 2.5 times and finally maternal addiction 3 times more than control group (p< 0.01). The mothers of our case group had prenatal care less than the control group. preterm labor had high incidence in mothers with pregnancy distance below than 2 years. We observed no significant relation between sex and prematurity.
