Determining the exact age of premature babies is important to predict growth and development and evaluate their health conditions. Are you confused about how to calculate the age of a premature baby? Is it from the time the baby is born or based on the estimated day of birth (HPL)? Come on, see the following explanation.
Premature babies are babies born when their mother's gestational age is less than 37 weeks. Parents of premature babies may be confused when asked how old their baby is. Should it be calculated according to gestational age or since the little one was born?
Calculating the Age of a Premature Baby
There are two ways to calculate the age of premature babies, namely based on chronological age and corrected age. Here's the explanation:
Chronological age is the age of the baby which is calculated from the time he was born. This age is not used as a benchmark, because the growth and development and function of the organs of premature babies are not like those of babies born at term. Chronological age is usually used to determine the immunization schedule for infants, both premature and full-term infants.
The corrected age is obtained from the chronological age minus the number of weeks or months in which the baby was born. For example, if the baby's chronological age is now 6 months, but he was born 2 months earlier, the corrected age is 4 months.
The corrected age of this premature infant can be used to evaluate its growth and development. Therefore, most doctors recommend using the corrected age until the premature baby is 2 years old, or until the baby is the same size and development as a full-term baby.
