Results
In echocardiographic analysis, RV and right atrial dimensions and areas
and RV wall thickness were higher in parous women. On the other hand, RV
systolic function parameters were significantly lower in parous women.
These significant changes showed a gradual increase or decrease by
increasing parity number. By multivariate hierarchical logistic
regression analysis, the 4 independent factors that increased the risk
of RV dilation were age (OR: 1.16 CI: 1.10 – 1.20), body mass index
(OR: 1.05, CI: 1.02 to 1.08), smoking (OR: 1.87, CI: 1.28 to 4.02), and
giving a birth (OR: 3.94 CI: 1.82 – 8.81). There were also independent
relationship between the number of parity and RV hypertrophy even after
adjustment for several confounders.
