pediatric PMH
chronic illness problems with organs cancers food allergies any medication
pediatric birth hx
full term
SGA?
LGA?
any complications prenatally or after delivery? infection?
pediatric family hx
obesity
short or tall?
delayed puberty
genetic or metabolic disorders?
hormones affecting growth during childhood
insulin-like growth factor 1
- birth till 20
- pulsatile secretions, 70% during sleep
thyroid hormone
- birth till 20
- stimulates GH, bone formation and reabsorption
Growth Hormone
- low at birth, peak around 5 and slow decline
Gonadal hormone
- 10-20, puberty
organ systems and weight
closely related to growth in stature and organ development.
influenced by: nutrition -> inc. number and size of adipose cells.
organ systems and length
skeletal growth is complete with epiphyses of long bones fuse: 90% or more of skeletal mass is present by 18.
lymph system growth
well developed at birth
grows rapidly, adult size by age 6, peak at 10-12
during adolescence the tissues decrease and stabilize
reproductive organ growth
grow slowly in prepubertal child but double in size during adolescence, full function and maturation during this time.
organs with quickest physical development
brain
skull
eyes
ears
fetal period growth of what dominates
head
infant period growth of what dominates
trunk
fat content and fetus
fat content of body increases slowly during fetal development, then rapidly accelerates the first 9 months of life
fastest growing during childhood
legs
- wt gained at a steady rate
fat and child growth
fat tissue inc. slowly until 7 years of age, then a prepubertal “fat spurt” occurs prior to the true linear growth spurt of puberty
adolescence growth
trunk and legs elongate
skeletal mass and organ systems double in size
males: broader shoulders and greater musculature
females: wider pelvic outlets
Height for infants
linear growth or recumbent length
- use from birth to 3 years
- measure to nearest 0.5cm or 1/4in
head circumference
measure until 3 years old
put tape around occipital protuberance and the supraorbital prominence
BMI and children
most common method used to assess nutritional status
< 5th percentile underwt
>85% over weight
>95% obese
