Birth weight by gestational age and risk of childhood acute leukemia: a population-based study 1961–2002

Aim of this study is to analyze determinants of breech presentation using information from two regional databases of Lombardy (Italy) including data on consecutive singleton breech and vertex deliveries occurred in the Region, between January 2010 and December 2015. Breech presentation occurred in 3.8% of all single deliveries. Main determinants of breech presentation at birth were: gestational age and birth weight (the lower, the higher the incidence of breech presentation), maternal age (the older the mother, the higher the risk of breech presentation), parity (the frequency of breech decreased with increasing parity) and previous cesarean section. Breech presentation resulted more frequent after assisted reproduction procedures.

Abstract Objective: To explore the associations between birth weight for gestational age (GA) and infant mortality as well as causes of infant death. Study design: A population-based observational study conducted between 2002 and 2012 included 203,620 non-malformed singleton live births from Slovenia. Poisson regression analyses were performed to estimate the crude relative risk (RR) and adjusted RR (aRR) for infant mortality by birth weight percentiles stratified by the GA subgroups term, moderate-to-late preterm, very preterm and extremely preterm. Results: Compared with appropriate for GA (AGA) term infants (referent-AGA), infant mortality was significantly higher in small for GA (SGA) term infants [aRR=2.79 (1.41–5.50)], with significant cause-specific infant mortality risk for neuromuscular disorders [RR=10.48 (2.62–41.91)]. The differences in infant mortality and cause-specific infant mortality in preterm subgroups between referent-AGA and SGA were insignificant. Conclusions: In the Slovenian population, birth weight for GA is significantly associated with infant mortality only in infants born at term.
