TL;DR
This hospital's increase in preterm births since 1978 parallels increases reported in population-based national studies from the United States and Canada, and this trend appears largely attributable to the increasing use of early ultrasound dating, preterm induction and preterm cesarean delivery without labor.
Abstract
This hospital's increase in preterm births since 1978 parallels increases reported in population-based national studies from the United States and Canada. This trend appears largely attributable to the increasing use of early ultrasound dating, preterm induction and preterm cesarean delivery without labor, and changes in sociodemographic and behavioral factors.

New England Journal of MedicineThe Contribution of Low Birth Weight to Infant Mortality and Childhood Morbidity
2,130 Citations1985Marie C. McCormick
Continuation of the current decline in neonatal mortality and reduction of the mortality differentials between high- and low-risk groups require the identification and more effective implementation of strategies for the prevention of low-weight births.
JAMAThe Validity of Gestational Age Estimation by Menstrual Dating in Term, Preterm, and Postterm Gestations
433 Citations1988Michael S. Kramer
The positive predictive values of the LNMP GA estimates decreased dramatically from term to preterm to postterm, and the systematic errors in menstrual GA estimates have profound implications for unnecessary induction, dysfunctional labor and cesarean section, and resultant neonatal and maternal morbidity.
The Future of ChildrenThe Problem of Low Birth Weight
394 Citations1995Nigel Paneth
Neither the low birth rate nor the preterm delivery rate has improved in the United States in the past quarter century, and most efforts to prevent prematurity or low birth weight, when carefully evaluated, have not proven effective.
New England Journal of MedicineDeterminants of Preterm Birth Rates in Canada from 1981 through 1983 and from 1992 through 1994
363 Citations1998K.S. Joseph, Michael S. Kramer +5 more
The recent increase in preterm births in Canada is largely attributable to changes in the frequency of multiple births, obstetrical intervention, and the use of ultrasound-based estimates of gestational age.
The LancetPregnancy and fetal long-chain 3-hydroxyacyl coenzyme A dehydrogenase deficiency
219 Citations1993Bridget Wilcken, Kit‐wah Leung +4 more
There may be adverse effects on maternal liver function from a fetus with LCHAD deficiency, and Heterozygosity in the mother cannot alone account for the adverse effects because of the segregation of these effects with fetal LCHad status.
American Journal of Public HealthNeonatal mortality: an analysis of the recent improvement in the United States.
217 Citations1980K S Lee, Nigel Paneth +3 more
It is a plausible hypothesis that improved perinatal medical care is a major factor in declining neonatal mortality in the U.S, and factors known to affect survival at a given birthweight have not changed in prevalence in the 25-year period.

188 Citations1985E Papiernik, Jean Bouyer +6 more
Findings enhance the hypothesis of a direct relationship between a prevention program and a reduction in preterm birth rates, and suggest improvements in pregnancy outcome do not disappear after standardization of mother's age, high blood pressure, or social class distribution.
International Journal of EpidemiologyThe New Danish Twin Register: Establishment and Analysis of Twinning Rates
177 Citations1995Kirsten Ohm Kyvik, Anders Green +1 more
An analysis of trends in the twinning rates for the years 1968-1982 showed that the rate of monozygotic twinning is increasing and the twinned rate of opposite-sex twin pairs is decreasing.

The results support the role of fatty acid accumulation in the pathogenesis of preeclampsia, and analysis for the prevalent mutation of this deficiency may be warranted in pregnancies with severe preeClampsia.

It is indicated that a significant subgroup of women with AFLP are heterozygous for LCHAD deficiency and that careful observation of their offspring for signs of this disorder is warranted.
American Journal of EpidemiologyMaternal Nutrition and Spontaneous Preterm Birth
138 Citations1992Michael S. Kramer, Frances H. McLean +2 more
It is concluded that prepregnancy weight-for-height and gestational weight gain are not important determinants of spontaneous preterm birth and that some previous studies have mistaken an effect of shortened gestation for its cause.
American Journal of EpidemiologyEpidemiology of Preterm Delivery in Two Birth Cohorts with an Interval of 20 Years
111 Citations1995Päivi Olsén, Esa Läärä +4 more
Despite a favorable change in the distribution of most of these determinants over the 20 years, only a small part of the decrease of the total incidence of preterm delivery could be attributed to these changes, as a consistent and substantial reduction occurred in the incidence of spontaneous preterm birth in all categories of each single determinant.
American Journal of Obstetrics and GynecologyPrematurity, postdates, and growth retardation: The influence of use of ultrasonography on reported gestational age
97 Citations1989Robert L. Goldenberg, Richard O. Davis +4 more
It is apparent that changes in use of ultrasonography had a profound effect on the reported gestational age distribution at the institution, with a decrease in the mean gestational Age and a risk in the reported preterm delivery rate.
Journal of General Internal MedicineImpact of the availability of a prior electrocardiogram on the triage of the patient with acute chest pain
70 Citations1990Thomas H. Lee, E. Francis Cook +4 more
When the current ECG is consistent with ischemia or infarction, the availability of a prior ECG for comparison to determine whether the ECG changes are old or new improves diagnostic accuracy and triage decisions by reducing the admission of patients without AMI or acute ischemic heart disease (increased specificity) without reducing the admitted of patients with these diagnoses.
PubMedRecent trends in infant mortality rates and proportions of low-birth-weight live births in Canada.
68 Citations1997K.S. Joseph, Michael S. Kramer
The proportion of low-birth-weight live births in Canada (excluding Ontario) appears to be stable, with Quebec showing significant reductions, and marginal increases in infant mortality observed in several provinces could be the result of random variation.
American Journal of Public HealthNeonatal technology, perinatal survival, social consequences, and the perinatal paradox.
57 Citations1995Robert M. Kliegman
The goal should be redirected to identifying large population-based efforts to reduce the number of low-birthweight infants, rather than having to treat the consequences of premature gestation.
Paediatric and Perinatal EpidemiologyDid preterm deliveries continue to decrease in France in the 1980s?
53 Citations1995Gérard Bréart, Béatrice Blondel +3 more
The reduction in preterm births cannot be attributed to the improved accuracy of gestational age determination, but the general use of ultrasound may have played a major role in the apparent reduction of the mean birthweight of preterm babies.
PubMedCurrent and future impact of rising multiple birth ratios on low birthweight.
28 Citations1997J A Martin, S M Taffel
For both white and black births, overall trends in low birthweight mask the disparate patterns of singleton and multiple births; it is, therefore, essential to examine lowBirthweight trends by plurality to assess accurately changes in this key indicator of infant health.
