Growth Flashcards
What does RNI stand for and what does it mean?
Reference nutrient intake = the amount of a nutrient that is enough to ensure that the needs of nearly all the population (97.5%) are being met
What does EAR stand for and what does it mean?
Estimated average requirement = is an estimate of the average requirement for energy, for a nutrient. Approximately 50% of the population will need less energy or the nutrient and 50% of the population will need more.
What does DRV stand for and what does it mean?
Dietary reference value = an estimate of the amount of energy and nutrients needed by different population groups of healthy people in the UK population
What does LRNI stand for and what does it mean?
Lower reference nutrient intake = the amount of a nutrient that is enough for only the small number of people who have low requirements (2.5%). The majority of the population will need more.
Summarize what the following are individually important for:
- EAR
- RNI
- LRNI
EAR is used for energy.
RNI is often used as a reference amount for population groups.
LRNI is a useful measure of nutritional inadequacy.
In ages 4-18 months, is protein generally over or under consumed?
Over - both girls and boys excees EAR across the board
Vitamin A
- Dietary sources?
- Intake above or below RNI?
Cheese, eggs, yoghurt
Above RNI for all age groups
Vitamin C
- Dietary sources?
- Intake above of below RNI?
Oranges, blackcurrants, potatoes
Below RNI for breast fed infants
Below RNI fpr non-breastfed infants
Which supplements are required for infants and under what conditions?
Recommended that from 6 months, all children consuming <500mls/d of infant formula should take vitamin A, C & D supplements. Proportion of children taking supplements ranged between 5% & 10%.
Breastfeeding mothers should take which supplement?
Vitamin D
Is sodium over or under consumed in infants?
Intake exceeded in all age groups except 4-6 months
What are the physical activity guidelines for:
- Infants not yet walking?
- Children capable of walking?
- 5-18 years?
- Encourage from birth, floor and water based activities
- 180 minutes throughout the day
- 60 minutes/day of moderate to vigorous intensity physical activity AND 3 days/week vigorous intensity activities
What time of feeding is recommended for newborns and for how long?
Exclusive breast feeding for first 6 months of infants life
At what age is breast milk no longer enough to meet nutritional needs?
What should you start doing here?
6 months
weaning
Full fat unmodified cows milk
- When and how should you introduce it?
- When should semi-skimmed milk not be given until?
- What about skimmed milk?
- Can be used in small amounts in cooking from 6-9 months
- Can be gradually introduced as a drink from 12 months
- Semi-skimmed milk should not be given before 2 years
- Skimmed milk should not be given before 5 years
When should you introduce complementary food?
- Gluten?
- Sugar and salt?
- Potential allergens?
- Nuts and seeds?
6 months
- First foods should be gluten free if <6months e.g. baby rice, cooked & mashed fruits & vegetables, peeled & mashed banana
- Sugar & salt should not be added; salty foods should be avoided
- Foods that may cause allergies should be introduced one at a time e.g. cereals with gluten, eggs, nuts, soya, fish, other milk
- Avoid whole nuts & seeds until 5 years
What are the three principles of complementary feeding?
- Adequate - to cover the nutritional needs of the child while breast feeding
- Appropriate - correct texture for age of child
Safe - clean water and good hygiene
Give three benefits of breastfeeding for the child
- Greater likelihood of higher IQ at 7½ years
- Lower obesity risk for baby in later life
- Lower maternal breast cancer risk
What is a z score?
The number of standard deviations from the mean
If 100 people are measures, how many are:
- Within 1 sd of the mean?
- Within 2 sd of the mean?
68
95
What is the age limit for true precocious puberty?
Girls <8
Boys <9
What are the age cut offs for pubertal delay?
Girls - 13
Boys - 14
Define:
- Thenarche
- Adrenarche
- Menarche
- Breast budding
- Body hair and odour
- Periods start (usually 2 years post thenarche)
Give the six classifications of short stature
- Genetic short stature
- Constitutional growth delay
- Dysmorphic syndromes
