title: Demographic and socioeconomic determinants of low birth weight and preterm births among natives and immigrants in Greece: an analysis using nationwide vital registration micro-data.
abstract: The present study makes use of nationwide individual-level vital registration data on the single live births occurring in Greece in 2006 to explore associations of socio-demographic factors with adverse pregnancy outcomes, using multinomial logistic regression models. The findings indicate that important risk factors associated with low birth weight preterm and intra-uterine growth retarded births (IUGR) include female sex, primiparity, age of mother over 35, illegitimacy and prior history of stillbirths, infant and child deaths. These constitute risk factors for normal weight preterm births as well, though associations with sex and primiparity in this case point to the opposite direction. Residing in large metropolitan areas is related to a greater risk of an IUGR birth. Among Greek women, educational attainment has a protective effect while housewife status is linked to higher chances of an IUGR birth. For immigrant mothers however, the opposite holds. The study also shows that normal weight preterm births form a distinct group.
