|Actual Study Start Date :||December 4, 1997|
Pregnant women with gestational age between 6 and 22 weeks
- Preterm delivery [ Time Frame: Ongoing ]Preterm delivery will be classified according to the immediate clinical antecedent of delivery (spontaneous preterm labor with intactmembranes, preterm premature rupture of membranes and pretermdelivery for maternal or fetal indications).
- Preeclampsia [ Time Frame: Ongoing ]Preeclampsia will be defined according to the following criteria:-Systolic blood pressure greater than or equal to 140 mmHg and/or diastolic blood pressure greater than or equal to 90 mmHg on twooccasions greater than or equal to 6 hours apart.-Proteinuria greater than or equal to 300 mg/24 hr or freater than or equal to 2+ (dipstick) on two occasions greater than or equal to 6 hours apart.-The diagnosis of severe preeclampsia will be made in the presence of any of the following: blood pressure greater than or equal to 160 mmHg (systolic) or greater than or equal to 110 (diastolic) on at least two occasions, proteinuria greater than or equal to 5 gr /24 hr, pulmonary edema, thrombocytopenia, oliguria, neurologic symptoms(headache, visual disturbances, persistent hyperreflexia, upperabdominal pain and HELLP syndrome). Eclampsia will be diagnosed if convulsions develop.
- Intrauterine growth restriction [ Time Frame: Ongoing ]Intrauterine growth retardation / small for gestational age infantA small for gestational age fetus will be considered that with a birth weight which is below the 10th percentile for gestational age. Additional cutoffs (5th and 3rd percentile) will also be explored.
