Correlations among outcomes and baby adipose tissue components
As shown in Table-2, regardless of the number of births of the
participants, both soft tissue thickness of the anterior abdominal wall
and total adipose tissue had significantly and positively correlated
with the type of delivery, active phase, and second stage duration,
birth weight of baby, biparietal diameter, abdominal circumference,
femur length, shoulder dystocia, labor protraction and labor arrest
(p<0.05).
Soft tissue thickness of thigh and arm was significantly and positively
correlated with the type of delivery, active phase duration, birth
weight of baby, biparietal diameter, abdominal circumference, femur
length, shoulder dystocia, labor protraction, and labor arrest
(p<0.05) (Table-2).
Participants were divided into two groups as nulliparous and parous.
Binominal logistic regression was used to determine the variables that
may predict labor prolongation, and labor arrest risk. According to this
analysis, while the increase in fetal abdominal adipose thickness causes
prolongation and arrest in labor. In the binary logistic regression
analysis, we performed, each 1mm increase in the anterior abdominal wall
adipose tissue causes prolonged labor in nulliparous groups 3.3 times
and 5.8 times in multiparous groups. Each 1 mm increase in total adipose
tissue components causes prolonged labor in nulliparous groups 2.4 times
and multiparous groups 2.9 times. Every 1 mm increase in the total
amount of adipose tissue thickness causes the arrest of labor in the
nulliparous group 1.6 times; in the parous group, it increases 1.4 times
(Table-3).
In the evaluation made with ROC analysis, we found that fetal adipose
tissue measurements in nulliparous and parous pregnant women had a
diagnostic value in predicting the prolongation, arrest of labor, and
cesarean section separately and in total. The recommended cut-off values
are shown in Table-4. According to this analysis, the presence of total
adipose tissue components of 21 mm and above in nulliparous women may
cause arrest in labor with 92% sensitivity and 74.1% specificity. In
the prediction of cesarean delivery in nulliparous women, we found this
cut off value to be 19.7 mm, with 76.9% sensitivity and 67.9%
specificity. We concluded that total adipose tissue components over 21.5
mm in women parous group caused labor arrest with 92% sensitivity and
78.7% specificity. We indicated the complete analysis in Table-4.
