# If BMI is >30 kg/m2, central obesity can be assumed and waist circumference does not need to be measured

WHO
The World Health Organization (1999)  requires the presence of any one of diabetes mellitus, impaired glucose tolerance, impaired fasting glucose or insulin resistance, AND two of the following:

Blood pressure ≥ 140/90 mmHg
Dyslipidemia: triglycerides (TG) ≥ 1.695 mmol/L  and HDL cholesterol ≤ 0.9 mmol/L (male), ≤ 1.0 mmol/L (female)
Central obesity: waist:hip ratio > 0.90 (male); > 0.85 (female), or BMI > 30 kg/m2
Microalbuminuria: urinary albumin excretion ratio ≥ 20 µg/min or albumin:creatinine ratio ≥ 30 mg/g

EGIR
The European Group for the Study of Insulin Resistance (1999) requires insulin resistance defined as the top 25% of the fasting insulin values among nondiabetic individuals AND two or more of the following:
Central obesity: waist circumference ≥ 94 cm or 37 inches (male), ≥ 80 cm or 31.5 inches (female)
Dyslipidemia: TG ≥ 2.0 mmol/L and/or HDL-C < 1.0 mmol/L or treated for dyslipidemia
Blood pressure ≥ 140/90 mmHg or antihypertensive medication
Fasting plasma glucose ≥ 6.1 mmol/L

NCEP
The U.S. National Cholesterol Education Program Adult Treatment Panel III (2001) requires at least three of the following:
Central obesity: waist circumference ≥ 102 cm or 40 inches (male), ≥ 88 cm or 35 inches(female)
Dyslipidemia: TG ≥ 1.7 mmol/L (150 mg/dl)
Dyslipidemia: HDL-C < 40 mg/dL (male), < 50 mg/dL (female)
Blood pressure ≥ 130/85 mmHg (or treated for hypertension)
Fasting plasma glucose ≥ 6.1 mmol/L (110 mg/dl)

American Heart Association
There is confusion as to whether, in 2004, the American Heart Association and National Heart, Lung, and Blood Institute intended to create another set of guidelines or simply update the National Cholesterol Education Program definition.
Postterm pregnancy is when a woman has not yet delivered her baby after 42 weeks of gestation, two weeks beyond the typical 40-week duration of pregnancy. Postmature births carry risks for both the mother and the baby, including fetal malnutrition, meconium aspiration syndrome, and stillbirths. After the 42nd week of gestation, the placenta, which supplies the baby with nutrients and oxygen from the mother, starts aging and will eventually fail. Postterm pregnancy is a reason to induce labor. Definitions
The management of labor and delivery may vary depending on the gestational age. It is common to encounter the following terms when describing different time periods of pregnancy. Postterm – ≥ 42 weeks + 0 days of gestation (> 293 days from the first day of last menstrual period, or > 13 days from the estimated due date)
Late term – 41 weeks + 0 days to 41 weeks + 6 days of gestation
Full term – 39 weeks + 0 days to 40 weeks + 6 days of gestation
Early term – 37 weeks + 0 days to 38 weeks + 6 days of gestation
Preterm – ≤ 36 weeks + 6 days of gestationBesides postterm pregnancy, other terminologies have been used to describe the same condition (≥ 42w+0d), such as prolonged pregnancy, postdates, and postdatism. However, these terminologies are less commonly used to avoid confusion.Postterm pregnancy should not be confused with postmaturity, postmaturity syndrome, or dysmaturity. These terms describe the neonatal condition that may be caused by postterm pregnancy instead of the duration of pregnancy.
