For example, with a 35-week gestational age delivery, a weight of 2,250 g (4 lb 15 oz) is appropriate for gestational age but is still low birth weight. One third of low-birth-weight neonates – infants weighing less than 2,500 g (5 lb 8 oz) – are small for gestational age. [citation needed] There is an 8.1% incidence of low birth weight in ...
Genetic diseases such as Turner's syndrome, Prader Willi, and Noonan syndrome can be marked by a less than 5th percentile height and weight since birth. [9] [10] [11] Other genetic disorders such as Marfan's syndrome and Klinefelter's syndrome are typically indicated by a height above the 90th percentile. [12] [13]
A low birth weight can be caused either by a preterm birth (low gestational age at birth) or the infant being small for gestational age (slow prenatal growth rate), or a combination of both. [10] Small for gestational age is defined as below the 10th percentile for gestational age and sex. [ 11 ]

In 2004, the World Health Organization began planning new growth chart references that could be used in all countries based on the WHO Multicentre Growth Reference Study (MGRS) (1997–2003). [2] The MGRS was a multifaceted study which gathered data from 8,500 children from widely differing ethnic backgrounds and cultural settings. [ 2 ]
Percentile growth charts, such as the figures created by the Centers for Disease Control and Prevention (CDC) shown on this page, are used to track growth by comparing children of similar age and sex. [4] The major percentile lines are the 95th, 90th, 75th, 50th, 25th, 10th, and 5th percentiles. [4]

Weight and height percentiles are determined by growth charts and body mass index charts to compare a child's measurements with those of other children in the same age group. By doing this, doctors can track a child's growth over time and monitor how a child is growing in relation to other children.
