(= Height: genetic index Defined as the vertical length from calvaria to vola Measurements <3 years: Supine length is measured using a fixed headboard >3 years: Erect height was measured in millimeters using a stadiometer fixed to the wall Typical patterns of hT gain 12 mo: 75 cm 2-12(yrs):age(yrs)×7+77
（二）Height: genetic index • Defined as the vertical length from calvaria to vola • Measurement: < 3 years: Supine length is measured using a fixed headboard. > 3 years: Erect height was measured in millimeters using a stadiometer fixed to the wall. • Typical patterns of HT gain 12 mo: 75 cm 2 – 12 (yrs): age (yrs) 7 ＋ 77
(uy)Head circumference and fontanel Related to intracranial volume Measured with a flexible tape marked in millimeters as the maximum circumference between the supra-orbital ridge and occiput birth: 32-34cm 6mo:42-44c1 I yr: 46cm 2 yrs: 48cm 6yrs:49-50cm;15yrs:54-58cm, Anterior fontanel about 1.5-2cm at birth, gradually ossification after 6 months. and close at 12 to 1 8 month Posterior fontanel: closed at birth in about 1/4 babies. for most babies. it close postnatal 6-8 weeks
(四）Head circumference and fontanel • Related to intracranial volume • Measured with a flexible tape marked in millimeters as the maximum circumference between the supra-orbital ridge and occiput. birth: 32-34cm; 6 mo: 42-44cm; 1 yr: 46cm; 2 yrs: 48cm 6 yrs: 49-50cm; 15 yrs: 54-58cm; • Anterior fontanel：about 1.5-2cm at birth, gradually ossification after 6 months, and close at 12 to 18 month. • Posterior fontanel: closed at birth in about ¼ babies, for most babies, it close postnatal 6-8 weeks
