Maternal and neonatal characteristics
Initially, a total of 380 patients were enrolled in the study; 223 women
were removed from the study based on the exclusion criteria stated
above. A total of 157 mothers were involved in this study with 98 women
(62.42%) detected HCA and 59 women (37.58%) detected non-HCA
eventually. The number of patients who met each exclusion criterion is
shown in Figure 1. Demographic and clinical characteristics, and the
risk factors of the mothers are given in Table 1. Mothers with or
without HCA were not significantly different in comparison to age,
interval of admission to delivery, incidence of multiple pregnancy,
infertility, gestational diabetes mellitus, cesarean delivery rate,
culture of vaginal secretion including streptococcus agalactiae (GBS),
mycoplasma and candidiasis (p>0.05)). Three characteristics
have shown significant, which are gestational age at admission (weeks),
gestational age at delivery (weeks), and birth weight (grams). The mean
gestational age at admission for the CON group was 32.27 weeks with
standard deviation 1.31 weeks, but for the HCA group was 30.09 weeks
with standard deviation 1.94 weeks. Both showed very strong significance
as the p-value was smaller than 0.001. Interval of admission to delivery
did not show significance between two groups as the p-value is 0.31.
There were only two women meeting the criteria of CCA in the CON group
(3.4%) and 7 women in the HCA group (7.1%), which showed no
significant difference with the p-value 0.485. Infants of
non-chorioamnionitis mothers were significantly heavier than those of
mothers in the HCA with the p-value being smaller than 0.001.
Specifically, the mean of the CON (HCA) group was 2052 (1772) grams with
standard deviation 284 (317) grams, respectively. Apgar scores in two
groups were similar.
