The bp_preg data set includes 209 women each with 30 minute recordings during the Pregnancy Day
Assessment Clinic (PDAC) observation window for up to a maximum of 240 minutes (i.e. a maximum
of 8 total readings per subject per observation window in addition to an initial "booking" reading
before the PDAC assessment). This recent study in obstetrics and gynecology investigated
pregnancy-induced hypertension (PIH) and pre-eclampsia (PE) prediction by analyzing cardiac and
physiological information to determine whether the blood pressure assessment of the first observation
window of 1 hour (60 minutes) was sufficient relative to the standard 4 hour (240 minute) window.
bp_pregA data frame containing 55 variables related to physiological assessment during pregnancy. The data variable dictionary is as follows:
Binary indicator for whether an individual exhibits abdominal pain (1 = yes) or not (0 = no)
Fetal heart rate accelerations
Admission from PDAC
Maternal age at estimated date of confinement
Alkaline phosphatase u/L
Alanaine transaminase u/L
Binary indicator for Antenatal diagnosis of pre-eclampsia 1 = yes, 0 = no
Current antihypertensive medication
Binary indicator for whether an individual is asymptomatic (1 = yes) or not (0 = no)
Baseline fetal heart rate (normal, bradycardia, tachycardia)
Body Mass Index
micromol/L
Cardiotocogram
Date of attendance modified by adding a random number of days between -7 and +7
Diastolic Blood Pressure
Fetal heart rate decelerations
Maternal date of birth modified by adding a random number of days between -7 and +7
Medical review during PDAC
Estimated date of confinement modified by adding a random number of days between -7 and +7

Final diagnosis: 0 = nil, 1 = pregnancy induced hypertension, 2 = pre-eclampsia
Gestational age (weeks) at attendance
Gamma glutamyl transaminase u/L
Gravidity: number of pregnancies including the current one
Binary indicator for whether an individual has a headache (1 = yes) or not (0 = no)
