Procedures
The enrolled subjects’ sociodemographic, clinical and anthropometric
characteristics, and flexibility, were assessed at the
16th w.g. Flexibility, height and weight were measured
again at the 34th w.g., along with abdominal muscle
thicknesses and the IRD. Birth and obstetric outcomes (duration of
labour, gestational age, type of birth, birth weight) were collected
from the subjects’ Pregnancy Health Documents and digital medical
records. Umbilical cord blood was collected at birth.
