4.1 Physical DevelopmentGrowing BodyAverage Weight & HeightAge 2: 10 to 14 kg 90 cm tallAge 6: 20 kg 120 cm tall=boys start becoming taller and heavier than girls on averageChanges in Body Shape and Structure2 yrs old vs 6 yrs old=varies in height, weight and shape=boys and girls become less round and moreslender=arms and legs lengthen and size relationship between the head and rest of body become adult like =by age 6 body is similar to those adults=internally, muscle size increases=eustachian tube in the ear changes it orientation causes earachesNutrition=rate of growth is slower than infancy, preschoolers need less foodOBESITY=body weight more than 20% higher than average weight for a person of a given age and height=encouraging children to eat more than theywant may lead to obesity=prevalence increasing over the last 20 yrs=low-fat, high nutrition foods, high in iron=iron-deficiency anemia causes constant fatigueHealth and IllnessCOMMON COLD (RUNNY NOSE)=average preschoolers experience 7 to 10 colds and other minor respiratory illnesses (3to 5 years old) *runny nose* =minor illnesses benefit children by building up immunity to more severe illnessesACCIDENT: INJURY=accidents pose great risk for preschoolers which injury is the leading cause of death among Canadian children due to high level ofphysical activity=fractures, open wounds, superficial wounds, head/neck and arm most common=boys typically more active than girls have higher rate of injuries=economic factors such as poverty in urban areas environment may contain hazardsLEAD POISONING =long-term hazard such as lead poisoning from putting objects in their mouths; lead is found in paint and gasoline, painted walls and window frames even dust and water=exposure to lead linked to lower intelligence, problems in verbal and auditory processing, hyperactivity and distractibility; highlevels of lead, antisocial behaviour, aggression and delinquency Growing Brain=brain grows at a faster rate than any other part of body2 yrs old: about ¾ size and weight of adult brain5 yrs old: 90% weight of avg adult’s brain weight=brain grows rapidly because of an increase in the number of interconnections among cells, supports complex communication between neurons and permits growth of cognitive=MYELIN which is protective insulation that surrounds parts of neurons increases, which speeds transmission of electrical impulses along brain cellsLinks Between Brain Growth and CognitiveDevelopment=growth spurts linked to advances in cognitive abilities=increases in myelin in the brain might be related to growing cognitive capabilities=MYELINATION of the reticular formation (area associated with attention and concentration) is completed by the time children are about 5; associated with attention span =by preschool, myelination in the hippocampus is completed associated in memory
