Wj. Hueston et al., THE EFFECTIVENESS OF PRETERM-BIRTH PREVENTION EDUCATIONAL-PROGRAMS FOR HIGH-RISK WOMEN - A METAANALYSIS, Obstetrics and gynecology, 86(4), 1995, pp. 705-712
Objective: To evaluate whether preterm-birth prevention educational pr
ograms are effective at reducing neonatal mortality, low birth weight
(LBW), and preterm delivery. Data Sources: A MEDLINE literature search
of English-language studies was performed, supplemented by a bibliogr
aphy search of original research and review articles to locate studies
assessing preterm-birth prevention programs. Method of Study Selectio
n: We identified 31 studies that reported results from trials evaluati
ng preterm-birth prevention programs. From this group, only the six ra
ndomized controlled trials evaluating preterm-birth prevention educati
on programs satisfied criteria of homogeneity to be included in a meta
-analysis. One of these six studies was a subset of another study and
was excluded except when reporting outcomes that were not included in
the larger report. Data Extraction and Synthesis: Two independent revi
ewers assessed study methodology and identified the following outcomes
: LBW frequency, preterm birth frequency, neonatal survival, birth wei
ght, gestational age at delivery, and preterm labor diagnosis rates. W
hen data were combined using meta-analytic techniques, no significant
benefits were found for preterm-birth education programs in preventing
neonatal death (cumulative relative risk [RR] 1.00, 95% confidence in
terval [CI] 0.99-1.01), LBW rates (RR 0.99, 95% CI 0.88-1.11), or pret
erm delivery rates (RR 1.08, 95% CI 0.92-1.27). The only statistically
significant effect of preterm birth education programs appears to be
an increase in the frequency at which preterm labor is diagnosed (RR 1
.71, 95% CI 1.41-2.08). Conclusion: Preterm-birth prevention education
al programs appear to have little benefit in reducing preterm birth an
d may result in an increased rate of diagnosis of preterm labor.
