However, the most commonly accepted way is to increment a person's age by 1 year on their birthday. There are many different ways a person's age can be calculated depending upon the culture they belong to. The formula for corrected age in premature infants is as follows: Number of Weeks Needed to Correct = Number of Weeks of Prematurity x 10įor example, if a child is ten weeks premature, it is estimated to take him or her 100 weeks to “catch up” to other babies his or her age.The Age calculator computes the age of a person based on his/her given date of birth. Though physicians vary on its usage, there are new findings that support the corrected age being used based on the number of weeks the baby is premature. This indicates that usage of the adjusted age before two years would eliminate unnecessary referrals for interventions, but that the adjusted age is no longer as necessary after 2 years of age. At 2 years of age, more than 90% of these same infants had positive scores on age-specific developmental tasks regardless of whether adjusted age was used. In a 1991 study, Ouden and colleagues found that, in the first year of life, 80-99% of premature infants achieved positive scores on age-specific developmental tasks when adjusted ages were used, while only 30-80% achieved positive scores when chronological ages were used. They do this because it normally takes premature babies roughly that long to “catch up” to babies who were born at term. Most healthcare professionals will use a corrected age with a child until he or she reaches between 2 and 3 years of age. For these reasons, it is important to know and discuss both ages of a premature baby with your child’s doctors. Some studies have shown that age adjustment is more important for motor skills than for cognitive skills, noting that premature infants tend to score significantly lower on motor skills than on mental skills in the first year of life. Medical professionals will usually ask for both chronological age and adjusted age at these appointments as part of the physical examination. Note: It’s important to talk to your child’s doctor about missed milestones or developmental concerns whether or not your baby was born prematurely.īabies born prematurely will be monitored more closely in clinical settings, because prematurity is considered a notable risk factor in a child’s development. Thus, the premature baby will not reach developmental milestones at the same time as a term baby would, meaning he or she will likely sit up unassisted later, begin to crawl later, and more. The adjusted age signifies that the baby was born prematurely, and therefore his or her brain and neurological system will not be as developed as a baby who was born at term. It is important to know a baby’s adjusted age, especially when it comes to developmental milestones. Adjusted Age = Chronological Age – Number of Weeks or Months Premature For example, if a baby’s chronological age is 3 months, but he or she was born one month early, the baby is said to have an adjusted age of 2 months. The adjusted or corrected age of the premature baby is the age of the baby based on the due date. The chronological age of a premature baby is the age of the baby from the date of birth. Since the 1930s, doctors have given preterm babies two ages: a chronological age and an adjusted or corrected age.
