The Contribution of Mild and Moderate Preterm Birth to Infant Mortality

Abstract

Mild- and moderate-preterm birth infants are at high RR for death during infancy and are responsible for an important fraction of infant deaths. JAMA. 2000;284:843-849

Parent ratings of child cognition and language compared with Bayley-III in preterm 3-year-olds

“…Current definitions from the World Health Organization differentiate extremely preterm (born ≤27 weeks gestation) from very preterm (born 28 to 31 weeks gestation (9) ). Other preterm infants can be categorised in moderate (born 32 to 33 weeks gestation (10,11) ), and late-preterm or mild-preterm (born at 34 to 36 weeks gestation (10,11) ). Modified versions of the PARCA-R displayed concurrent validity with the Bayley Scales of Infant Development-II Mental Development Index in very preterm (12) , moderate preterm (13) , as well as late and moderately preterm toddlers (14) at age two years.…”

A prospective study to investigate the relationship between periodontal disease and adverse pregnancy outcome

“…6 It has also been shown that babies born prematurely are more prone to future neurological problems 7 and perhaps cardiovascular and respiratory disease in later life. 8 Preterm birth can be more extreme, such as delivery at less than 32 weeks gestation: 9 this has been shown to increase further the risk of adverse sequelae. If birth occurs before 24 weeks of gestation it is termed miscarriage as the fetus is categorised as non-viable 10 but can still be regarded as a very extreme form of preterm birth.…”

Short-Term Outcomes and Mortality of Late Preterm Infants

“…Although clinical investigations and statistics have traditionally focused on premature infants born at a gestational age of 32 weeks or less, this increase is related to the increase in late preterm births and compared to term births, late preterms have increased risk of mortality and morbidity (1). National Institute of Child Health and Human Development (NICHHD) defines late preterm births as births between 34 0/7 to 36 6/7 weeks (2).…”
