“…The analysis included the following control variables: socioeconomic status (based on the socioeconomic classification used as a reference for our country), 33 teenage mother (,19 years old at the time of birth), NICU admission, small for GA (birth weight ,10th percentile according to validated tables for Chilean population), 34 gender, multiple birth, and ASQ administration age (8 or 18 month). Analyses were performed by using R (Vienna, Austria) and Stata 12 (StataCorp, College Station, TX) platform statistics with a linear trend module.…”

OBJECTIVES: The objective of this study was to evaluate the association between gestational age (GA) at birth and risk of developmental delay at 8 and 18 months of corrected postnatal age. METHODS: During 2008 to 2011, infants at a corrected postnatal age of 8 or 18 months attending health centers in Santiago, Chile, were recruited. Participants completed a form on biographical and demographic characteristics and the Chilean validated version of the Ages and Stages Questionnaires, Third Edition (ASQ). Logistic regression was used to detect the capacity of GA to predict scores < −2 SDs on the basis of the Chilean ASQ reference group, in at least 1 ASQ domain, adjusted by different control variables. RESULTS: A total of 1667 infants were included in the analysis. An inverse “dose response” relationship between developmental delay risk and GA at birth was found, both in the crude and adjusted models. Compared with those born full term, the odds ratio for developmental delay risk was 1.56 for those born early term (95% confidence interval [CI]: 1.19–2.06), 2.58 for infants born late preterm (95%CI: 1.66–4.01), and 3.01 for those born moderately preterm (95%CI: 1.59–5.71). CONCLUSIONS: An inverse dose-response relationship between GA and risk of developmental delay was found in the tested population. Future prospective studies and predictive models are needed to understand whether this higher developmental risk in moderately and late preterm infants is transient and modifiable or persists throughout life, allowing for better targeting of early-intervention strategies.

RESUMENObjetivo: Conocer la mortalidad perinatal del parto prematuro y los factores de riesgo asociados, usando los datos perinatales clínicos, los resultados de laboratorio y los hallazgos patológicos del feto, neonato y placenta. Métodos: Estudio retrospectivo, cohorte de 407 nacimientos prematuros, únicos, entre 22.0 y 34.0 semanas de gestación. Se estudiaron las muertes fetales y neonatales hasta los 7 días de vida. Fallecieron 122 niños (64 muertes fetales y 58 neonatales), 78 tuvieron autopsia. Resultados: La mortalidad perinatal fue de 30% (122/407). El 71% (87/122) de las muertes ocurrieron antes de las 30 semanas y el 81% (99/122) en nacidos con peso menor de 1500 gramos. Las principales causas de muerte perinatal según el factor asociado con el parto prematuro fueron: infección bacteriana ascendente (IBA) 41% (50/122), anomalía congénita 20% (24/122) e hipertensión arterial 12% (15/122). Los factores de riesgo de muerte perinatal, identificados mediante análisis de regresión logística, fueron: edad gestacional al parto (p<0,001), anomalía congénita (p<0,001), IBA (p=0,02) e hipertensión arterial (p=0,03). Las principales causas de muerte perinatal fueron: hipoxia (aguda o crónica) 28%, infección congénita 23% (preferentemente neumonía 18%), desprendimiento prematuro de placenta con hipoxia y shock hipovolémico 18%, anomalía congénita 18% y síndrome hipertensivo con hipoxia aguda o crónica 7%. Conclusiones: Entre las 22 y 34 semanas de gestación, el parto prematuro por IBA fue la causa más frecuente de muerte perinatal, la edad gestacional al parto fue el principal factor de riesgo de mortalidad y la hipoxia fue la causa más frecuente de muerte. PALABRAS CLAVE: Mortalidad perinatal, nacimiento prematuro, infección congénita SUMMARY Aim:To determine perinatal mortality of premature birth and the risk factors associated using perinatal clinical data, laboratory results and histopathological fetal, neonatal and placental findings. Methods: Retrospective cohort study of 407 preterm single births at 22.0-34.0 weeks gestation. Fetal and neonatal deaths until 7 days of life were studied. One hundred and twenty two children died (64 fetal deaths and 58 neonatal deaths), 78 had autopsy. Results: Perinatal mortality was 30% (122/407). Of total deaths, 71% (87/122) occurred before 30 weeks gestation and 81% (99/122) occurred in very low birth weight infants (<1500 g). The main causes of perinatal mortality according to associated factors for premature birth were: ascending bacterial infection (ABI) 41% (50/122), congenital anomalies 20% (24/122) and hypertension 12% (15/122).
