Study Notes
Measuring Circumference
- Measure the head circumference by placing the measuring tape around the largest circumference of the infant's head, across the occiput and forehead.
- Measure the chest circumference by wrapping the measuring tape around the infant's chest at the nipple line, firmly but not tight enough to cause an indentation of the skin.
- Read the chest circumference measurement midway between inspiration and expiration to the nearest 0.5 cm or 0.25 inch.
Head-to-Chest Circumference Comparison
- In newborns, the head circumference may equal or exceed the chest circumference by 2 cm (0.75 inches) until 5 months of age.
- Between 5 months and 2 years, the infant's chest circumference and head circumference are close to the same size.
- If an infant's head circumference is smaller than the chest circumference, consider evaluating the infant for microcephaly.
- After 2 years of age, the chest circumference exceeds the head circumference because the chest grows faster than the head.
Gestational Age
- Gestational age is an indicator of a newborn's maturity.
- Gestational age can be calculated by counting the number of completed weeks between the first day of the mother's last menstrual period and the date of birth.
- The Ballard Gestational Age Assessment Tool evaluates six physical and six neuromuscular newborn characteristics to establish or confirm the newborn's gestational age.
- The assessment is accurate within 2 weeks of the assigned gestational age.
- Gestational ages of 37-41 weeks are considered term and are associated with the best health outcomes.
Size for Gestational Age
- A newborn's fetal growth pattern and size for gestational age can be determined using an intrauterine growth curve.
- The Fenton Growth Chart is recommended for tracking premature growth until 50 weeks postmenstrual age.
- Infants are classified as small, appropriate, or large for gestational age by percentile curve placement for weeks of gestation.
- Small for gestational age infants have an increased risk for morbidity and mortality.
- Infants who are small or large for gestational age have an increased risk for health problems.
