Neonatal morbidity associated with late preterm and early term birth: The roles of gestational age and biological determinants of preterm birth
Background: The aim of this study was to elucidate the role of gestational age in determining the risk of neonatal morbidity among infants born late preterm (34-36 weeks) and early term (37-38 weeks) compared with those born full term (39-41 weeks) by examining the contribution of gestational age within the context of biological determinants of preterm birth.Methods: This was a retrospective cohort study. The sample included singleton live births with no major congenital anomalies, delivered at 34-41 weeks of gestation to London-Middlesex (Canada) mothers in 2002-11. Data from a city-wide perinatal database were linked with discharge abstract data. Multivariable models used modified Poisson regression to directly estimate adjusted relative risks (aRRs). The roles of gestational age and biological determinants of preterm birth were further examined using mediation and moderation analyses.Results: Compared with infants born full term, infants born late preterm and early term were at increased risk for neonatal intensive care unit triage/admission [late preterm aRR = 6.14, 95% confidence interval (CI) 5.63, 6.71; early term aRR = 1.54, 95% CI 1.41, 1.68] and neonatal respiratory morbidity (late preterm aRR = 6.16, 95% CI 5.39, 7.03; early term aRR = 1.46, 95% CI 1.29, 1.65). The effect of gestational age was partially explained by biological determinants of preterm birth acting through gestational age. Moreover, placental ischaemia and other hypoxia exacerbated the effect of gestational age on poor outcomes.Conclusions: Poor outcomes among infants born late preterm and early term are not only due to physiological immaturity but also to biological determinants of preterm birth acting through and with gestational age to produce poor outcomes. © The Author 2013; all rights reserved
Health-related quality-of-life measures for long-term follow-up in children after major trauma
Objective: Our objective was to review measures of health-related quality of life (HRQL) for long-term follow
up in children after major trauma and to determine the measures that are suitable for a large age range, reliable
and valid, and cover a substantial amount of the domains of functioning using the International Classification of Functioning, Disability, and Health (ICF) of the World Health Organization (WHO).
Methods: The Medline and EMBASE databases were searched in all years up to October 2007 for generic HRQL
measures suitable for children aged 5-18 years old and validated in English or Dutch. Measures were reviewed with
respect to the age range for which the measure was suitable and reliability, validity, and content related to the ICF.
Results: The search resulted in 1,235 hits and 21 related articles. Seventy-nine papers met the inclusion criteria, describing in total 14 measures: Child Health and Illness Profile Adolescent and Child Edition (CHIP-AE/CE), Child Health Questionnaire Child and Parent Forms (CHQCF87/PF50/PF28), DISABKIDS, Functional Status II (FS II)(R), Health Utilities Index Mark 2 (HUI 2), KIDSCREEN 52/27, KINDL, Pediatric Quality of Life
Inventory (PedsQL), TNO Institute of Prevention and Health and the Leiden University Hospital (TNO-AZL),
TNO-AZL Children’s Quality Of Life (TACQOL), and Youth Quality of Life Instrument-Research Version
(YQOL-R). Measures that were suitable for a large age range were CHQ-PF50/PF28, DISABKIDS, FS II(R), HUI
2, KIDSCREEN, PedsQL, and TACQOL. All measures had moderate to good psychometric properties, except for
CHQ-PF50/PF28, KINDL, and TACQOL, which had either low internal consistency or bad test-retest reliability.
The measures that covered more than six chapters of the ICF domains were CHIP-AE/CE, CHQ-CF87/PF50, DISABKIDS,
KIDSCREEN-52, PedsQL, and TACQOL.
Conclusions: DISABKIDS, KIDSCREEN 52, and Peds-QL are suitable for long-term follow-up measurement of
HRQL in children after major trauma. They cover a large age range, have good psychometric properties, and cover
the ICF substantially
