The association of pattern of maternal weight gain with length of gestation and risk of spontaneous preterm deliveryPaediatric and Perinatal Epidemiology - Tập 11 Số 4 - Trang 392-406 - 1997
Suzan L. Carmichael, Barbara Abrams, Steve Selvin
Monitoring weight gain during pregnancy may be useful in detecting pregnancies
that are at increased risk of early delivery. This study examines 7259
deliveries that occurred at the University of California, San Francisco's
Moffitt Hospital from 1980 to 1990. Obese women, women with diabetes or
hypertension during pregnancy, deliveries with congenital malformations and
non‐spontaneous preterm deli... hiện toàn bộ
Necrotising enterocolitis hospitalisations among neonates in the United StatesPaediatric and Perinatal Epidemiology - Tập 20 Số 6 - Trang 498-506 - 2006

SummaryThe objective of this study was to estimate the rate and describe the
epidemiology of necrotising enterocolitis (NEC) among neonates (infants <1 month
of age) hospitalised in the United States. Hospital discharge records for
neonates with an NEC diagnosis and an in‐hospital death or routine discharge
were selected for analysis from the 2000 Kids’ Inpatient Database. An estimated

Pregnant women at work: rest periods to prevent preterm birth?Paediatric and Perinatal Epidemiology - Tập 3 Số 1 - Trang 19-28 - 1989
N Mamelle, I Bertucat, F Munoz
Summary. The aim of this study is to identify social preventive measures in an
attempt to prevent pre‐term birth in pregnant women who work under strenuous
conditions. A study carried out in 50 factories allowed us to gather data on
1168 pregnancies that occurred during 1 year and to study the modifications in
working conditions now granted to pregnant women in many firms in France. We
observed a ... hiện toàn bộ
A comparison of LMP‐based and ultrasound‐based estimates of gestational age using linked California livebirth and prenatal screening recordsPaediatric and Perinatal Epidemiology - Tập 21 Số s2 - Trang 62-71 - 2007

SummaryAlthough early ultrasound (<20 weeks' gestation) systematically
underestimates the gestational age of smaller fetuses by approximately 1–2 days,
this bias is relatively small compared with the large error introduced by last
menstrual period (LMP) estimates of gestation, as evidenced by the number of
implausible birthweight‐for‐gestational age. To characterise this
misclassification, we comp... hiện toàn bộ
The research implications of the selection of a gestational age estimation methodPaediatric and Perinatal Epidemiology - Tập 21 Số s2 - Trang 86-96 - 2007
Courtney D. Lynch, Jun Zhang
SummaryThere are three primary methods of gestational age estimation: dating
based on last menstrual period (LMP), ultrasound‐based dating and neonatal
estimates. We review the strengths and limitations of each method as well as
their implications for research. Dating based on LMP is a simple, low‐cost
method of estimating gestational age. Limitations associated with the use of
menstrual‐based dat... hiện toàn bộ
Molecular epidemiology of preterm delivery: methodology and challengesPaediatric and Perinatal Epidemiology - Tập 15 Số s2 - Trang 63-77 - 2001

Preterm delivery (PTD) appears to be a complex trait determined by both genetic
and environmental factors. Few studies have examined genetic influence on PTD.
The overall goal of our study is to examine major candidate genes of PTD and to
test gene–environment interactions. Our study includes 500 preterm trios,
including 500 preterm babies and their parents and 500 maternal age‐matched term

Preterm labour and delivery: a genetic predispositionPaediatric and Perinatal Epidemiology - Tập 15 Số s2 - Trang 57-62 - 2001
Donna Dizon‐Townson
Preterm delivery (PTD) complicates as many as 10% of pregnancies in the United
States. Moreover, prematurity accounts for more than 70% of the consequent
neonatal and infantile morbidity and mortality. Serious long‐term complications
include cerebral palsy, respiratory disease, blindness and deafness. Despite
substantial basic scientific, translational and clinical investigation in recent
years, t... hiện toàn bộ
Gestational age‐specific birthweight of twins in vital recordsPaediatric and Perinatal Epidemiology - Tập 12 Số 3 - Trang 347-351 - 1998
Michael Cooperstock
Analysis of singleton preterm birth from vital statistics data is hampered by
inaccurate gestational age dating. This is most notably evidenced by the large
fraction of implausibly high birthweights for gestational age given in birth
records. Using natality statistics for New England, 1977–88, birthweight
distributions were plotted for representative preterm gestations. Confounding by
improbable b... hiện toàn bộ
