ABSTRACT: Background/Aims:
It is known that high pre-preg-nancybody mass index (BMI) and high gestational weight gain both can cause many
adverse pregnancy outcomes. High pre-delivery BMI (PD-BMI), though
theoretically could do similar effects, is rarely been studied. The objectives
of this study were to show the distribution of PD-BMI of the delivery women and
to identify its correlation with adverse pregnancy outcomes. Methods: This
study was a cross sectional study. Data were collected retrospectively from hospital electronic database of Lampang Regional Hospital (LPH) along with manual
retrieval from medical charts and labor records. Data of all pregnant women who
delivered at labor room were collected from 1st February 2011 to 31st August
2012. After preterm and multifetal pregnancies were excluded, 4999 cases were
into the analysis. Descriptive and inferential data analyses were used with
both univariate and multivariate methods. Results:
In this group of women, 93.9% were in the PD-BMI range of 20.0 -34.9 kg/m2. After multivariate
analysis was used, higher PD-BMI was shown to be correlated with higher
cesarean section, neonates weighing ≥3500 gmand long neonatal length with relative risk
(RR) and 95% confidence interval (95% CI) of
1.11 (1.09 - 1.13), 1.15 (1.12 - 1.17) and 1.07 (1.05 - 1.09), respectively.
Conclusions: High PD-BMI was correlated with multiple adverse pregnancy
outcomes. Interestingly, their effect sizes were much smaller comparing to high
pre-pregnancy BMI and high gestational weight gain. It confirmed the current
recommendations to monitor pre-pregnancy BMI and gestational weight gain to
avoid unwanted morbidities.
