Table 1 Diagnostic criteria used for the study on determinants of pre-eclampsia among women attending hospitals in Omo district, Southern Ethiopia, 2018

From: Family history of chronic illness, preterm gestational age and smoking exposure before pregnancy increases the probability of preeclampsia in Omo district in southern Ethiopia: a case-control study

Diagnostic criteria for pre-eclampsia [28]
The onset of symptoms after 20 weeks’ gestation with remission by 6–12 weeks postpartum*
Mild pre-eclampsia:
 • Hypertension (Systolic Blood Pressure(SBP) ≥ 140 mmHg or Diastolic Blood Pressure(DBP) ≥ 90 mmHg), may be superimposed on chronic hypertension
 • Proteinuria (proteinuria ≥300 mg/24 h, or significant increase from baseline)
Severe pre-eclampsia if one or more of the following:
 • Sustained Systolic Blood Pressure(SBP) ≥ 160 mmHg or Diastolic Blood Pressure(DPB) ≥ 110 mmHg (measured twice, at least 6 h apart)
 • Evidence of other end-organ damage
  • Deteriorating renal function including nephrotic range proteinuria ≥3 g/24 h or 3+ on urine dipstick or sudden oliguria, especially with elevated creatinine
  • Central Nervous System(CNS) disturbance (altered vision, headache)
  • Pulmonary edema (3% of patients)
  • Liver dysfunction
  • Epigastric/right upper quadrant pain (stretching of hepatic capsule)
  • Thrombocytopenia (15–30% of patients)
  • HELLP syndrome is characterized by Hemolysis Elevated Liver enzymes and Low platelet count which may occur without proteinuria.
  • Evidence of fetal compromise (Intrauterine Growth Restriction-IUGR, oligohydramnios, non-reasoning fetal testing)
