Growth and Development Flashcards
what is the z-score/standard deviation score
number of standard deviation from the mean
when does a child show normal growth
Their measurements are within the normal range compared with children of their age
Their rate of growth is within the normal range compared with children of their age
how should babies be weighed
without any clothes or nappies
how should children older than 2 be weight
in vest and pants
but not in shoes or anything in their hands
rule for plotting on a growth chart
- record measurement and date in ink, plot in pencil
- use dot, do not join up
- age in weeks for first 6-12 months
- calendar months thereafter
what is a centile space

what is average age of girls entering puberty
11
what do we use to stage puberty
Tanner system
what are the stages of female puberty

Menarche - periods start (usually 2 years post thelarche)
when is puberty considered delayed
the absence of secondary sexual development in a girl aged 13 or a boy aged 14 years
what are the principle of development
Continuous process
Maturation of nervous system - development is dependant on this
Sequence same but rate varies
Cephalocaudal direction - head to tail. Start with gaining head control and then trunk and then legs.
Generalised mass activity changing to more specific controlled movements
what are the 4 areas of development
Gross motor
Fine motor and vision
Language and hearing
Social behaviour and play
what are the milestones for gross motor development
Head control - 3 months Sitting balance - 6 months Crawling - 9 months Standing - 12 months Runs - 18 months Stairs – 2 feet/tread - 24 months Stairs – alternate feet - 36 months Hops - 48 months
what are the primitive reflects of motor development
Sucking and rooting (baby feels breast touch cheek, baby instinctively know to turn)
Palmar and plantar grasp (something placed on palm of hand or plantar of foot, fingers/toes will curl round)
ATNR (if head falls back, babies arm move to curl round as if to grab something)
Moro
Stepping and placing
what does ATNR stand for
asymmetrical tonic neck reflex
what are the milestones for fine motor and vision
Hand regard in midline - 3 months Grasps toy - palmar - 6 months Scissor grasp - 9 months Pincer grasp - 12 months Tower of 3-4 bricks - 18 months Tower of 6-7/scribble - 24 months Tower of 9 bricks/copies circle - 36 months Draws simple man - 48 months
