Child Development Flashcards
What are the stages of child development?
Baby – 0-1 year of age
Infant – 0- 2 years of age
Childhood – 2 -10 years of age
Pubertal - 10 years to adult
Where are growth charts held?
Parent held child health record (red book)
Which groups of children require adjustments to their growth charts or special charts?
Adjust chart for prematurity - less than 37 weeks
Special charts for Down’s syndrome and other common conditions
What measurements are recorded in the red book?
Weight
Length/Height: Infants
What is crossing a centile?
Crossing a centile line drawn on the centile chart
With regards to crossing centiles, when would you refer a child?
Refer a child who has fallen through 2 centiles
What might be causes of a child being small and thin?
Low weight, low height = Failure to thrive
Under nutrition
Chronic disease e.g. asthma, coeliac, cystic fibrosis, congenital heart malformations
Genetic Syndromes
Neglect
What can be causes of a child being tall and thin?
Most likely normal but monitor growth if concerned
Check weight following centiles
Some rare syndromes e.g. Marfan’s
What centiles would a tall overweight child fit into?
Ht 75 centile
Wt >98 centile
What are risks of a child being tall and overweight?
Early puberty and subsequent short stature
What could cause a child to be short and overweight?
Weight»_space; height
Growth hormone deficiency
Hypothyroidism
Describe the vicious cycle of childhood obesity
Healthy child watches TV, eats snacks, under active -> mildly obese child
Make excuses for less activity and gain further weight -> moderately obese child
Exercise becomes uncomfortable and physically difficult -> severely obese child
Develop conditions such as asthma, diabetes, MSK, CAD which prevent exercise through to adulthood -> obese adult
What is a head circumference measurement?
Occipito-frontal circumference – OFC
Measures brain growth
80% of brain growth before age 5 years
Paper tape measure
Describe infant brain growth
At full-term, baby’s brain has 100 billion neurons
Brain not fully developed, has to be “wired up” after birth and baby’s brain will increase in weight from 400g at birth, to 1000g at 1 year p
Increase in weight is caused by proliferation of synapses
What does proliferate and prune mean?
During sensitive period of brain development, proliferation of synapses Large numbers are generated in short space of time
Active synapses that are used will be stabilised and remain and ones not used will be “pruned”
“use it or lose it”
When does development of the orbitofrontal regions occur?
Post natally
How are experiences incorporated into developing synaptic connections?
Experience-expectant: environmental input that everyone experiences, which play a necessary part in organising developing nervous system eg visual cortex which expects to be exposed to light and patterned visual information and needs this experience for normal development
Experience-dependent mechanisms: unique experiences of each individual baby produces a unique wiring of their brain and therefore enables them to adapt to specific features of individual environment that they inhabit
What are important Experience-expectant aptitudes?
Sensory pathways of vision and hearing, social and emotional development, language and higher cognitive functions
Sets the scene for experience-dependent experiences, which supply the more detailed script based on each child’s individual experiences
When is experience dependant development optimised?
When it takes place during sensitive developmental periods
However, it can take place at any time not just during sensitive developmental period (defining characteristic)
Brain is plastic across lifespan which makes it possible for us to change our behaviours, learn new skills and recover following a stroke
What are the developmental domains?
Physical – posture, gross and fine motor/vision Cognitive Social and emotional Communication – speech and language/ hearing Locomotion Manipulation Speech/Language Behaviour
How can we assess development?
Use developmental milestones which are behaviours or physical skills
What are the Mary Sheridan (From Birth to Five Years) Stages of development Domains?
Posture and large movements
Vision and fine movements
Hearing and speech
Social behaviour and play
What are the five domains of the age and stage questionnaire?
Communication Gross motor Fine motor Problem solving Personal and social
What are reasons for developmental delay?
Chronic illness
Lack of stimulation
Sensory impairment
Developmental disorder
