Social differences of very preterm birth (22-32 completed weeks of amenorrhea) were studied using data from a large case-control survey in Europe between 1994 and 1997 ; 1,675 very preterm births and 7,965 full-term births were included.
The relation between social factors and very preterm birth was studied according to obstetric history and the mode of delivery onset.
Very preterm birth was significantly related to low educational level among women with no previous adverse pregnancy outcome (odds ratio (OR)=2.67,95 percent confidence interval (Cl) 1.66-4.28) and among primigravid women and those with previous first-trimester abortion (OR=2.01,95 percent CI 1.56-2.58).
In this group, unemployment of all household members was associated with a double risk of very preterm birth.
No significant association between very preterm birth and socioeconomic status was observed among women with previous second-trimester abortion or preterm birth.
Socioeconomic indicators remained significantly associated with both spontaneous and induced very preterm births among women with no previous late fetal loss or preterm birth.
The results are consistent with social factors affecting the risk of very preterm birth, but the relation differs according to obstetric history.
