Flashcards in Growth and physical dev. Deck (27):
1

2 fastest periods of growth

intrauterine and infancy

2

6 influences on growth

1. genes
2. health
3. nutrition
4. hormones
5. env.
6. drugs

3

3 factor affecting intrauterine growth

1. fetal
2. placental
3. maternal

4

3 measurements of growth

1. ht, wt, HC

5

how to use charts for preemies

use the corrected age (how old they should have been)

6

2 different charts and their diffs

1. CDC - reference to the normal of pop
2. WHO - reference to ideal

7

when is BMI used and how is it measured

>2yo kg/m2

8

*what is avg. HC at birth and growth in first year

35cm and 12 cm

9

*what is avg. wt at birth and 5 months and a year

birth - 3.5 kg
5 mon - doubled
year - tripled

10

*height at birth

50cm

11

*what is growth velocity in cm/yr in childhood

6cm/YR

12

what percentile is important for ht (2)

1. falling under 3%
2. crossing %iles after age 2

13

what is most important when loking at growth

velocity more important than absolute

14

*what is parental height facotr

90% should fall within 2 SD of parents height

15

* calc. for midparental height

male = father + (discrep + mother)/2
female = mother + (father-discrep)/2

16

markers and times of female puberty

7-13yo
1. breast dev.
2. growth spurt
3. menarche - growth almost complete

17

what is common and patho in puberty timing in females

early - common
late - patho

18

markers and times of male puberty

9-14
1. teste dev.
2. later growth spurt

19

what is common and patho in puberty timing in males

early- patho
late - common

20

**4 questions that provide all answers about short stature

1. was child IUGR
2. is child disproportionate
3. is velocity normal or delayed
4. is bone age normal or delayed

21

what if IUGR was present

maternal - health, nutrition, infection, size, drugs
fetal - genes, multiple gest
placental - insuff. TTTS

22

what is proportion important

most cause that at disproportionate are bony in nature should be 1:1

23

bony causes

short trunk - spinal rad. , kyphoscoliosis
short limbs - achondro, rickets

24

why is velocity important

normal growth velocity assoc. with normal variants - while slow velocity is associated with patho

25

why is bone age important

more delayed the bone growth, the more likely something organic

26

5 causes of slow grorth velocity

1. malnutrition
2. chronic disease
3. psychosocial dep.
4. drugs
5. endocrine disorders

27

what does normal bone age indicate

familial short stature
