 Gestation Period and Gestational Age Encyclopedia of Childhood and Adolescence - Find Articles
The gestational age of a fetus or newborn infant corresponds to how far along it is in the gestation period, usually measured in weeks and days from the first day of the mother's last menstrual period.
Knowledge of the gestational age is important in assessing whether or not a pregnancy is progressing normally and also in evaluating the health status of a newborn.
Gestational age is also used as a baseline to identify babies who are at risk because of their small size--small for gestational age (SGA) or small for date (SFD).

 MedlinePlus Medical Encyclopedia: Appropriate for gestational age (AGA)
Appropriate for gestational age, or AGA, describes a fetus or newborn infant whose size is within the normal range for his gestational age.
Assigning size such as SGA (small for gestational age), LGA (large for gestational age), or AGA is a way to measure and monitor the growth of the infant throughout the pregnancy as well as at the time of birth.
The measurement is calculated based on the estimated gestational age (how many weeks the mother was pregnant) in comparison to what is considered normal height, weight, head size, and developmental level for a child of the same gestational age and gender.

The human gestation period- the period of time between conception and labor- is approximately forty weeks (280 days), measured from the first day of the mother's last menstrual period.

 Men Born Preterm at Increased Risk for High Blood Pressure - CME Teaching Brief® - MedPage Today
Men who were born at less than 29 weeks of gestational age had almost double the risk for high systolic blood pressure of men born at full term, reported neonatologist Stefan Johansson, M.D., of the Karolinska Institute here.
What's more, being born small for gestational age was associated with a 10% increased risk for elevated systolic blood pressure compared with being born of average size for gestational age.
There was also an association between decreased gestational age and an increased risk for elevated diastolic blood pressure, but this only appeared to be significant for men born at 33 weeks gestation or later, the researchers said.
