Infant and Childhood nutrition Flashcards
What measurements are infant growth/maturation determined by?
-length/height
-weight
-head circumference
What is the stomach capacity at birth compared to that of a 1 month old
20-90mL or 0.7-3 ounces at birth
90-150mL or 3-5 ounces at 1 month old
True or False: human milk empties more rapidly than formula from the stomach
True, this means more frequent feedings are required
What part of the GI tract affects the nutrient absorption
The small intestine which is very short in length in an infant
In what year of life do the GFR values reach adult values
the 3rd year of life
*filtration begins in the fetus during week 9 of development
When do all the characteristics of nutritive sucking develop?
swallowing develops by end of first trimester(12-13weeks)
sucking develops at 22-23 weeks gestation
effective sucking(rhythmic alternation between suction and swallowing) develops at 33-34 weeks of gestation
nutritive sucking develops at 33-34 weeks with a full mature pattern occurring at 37 weeks gestation
What is different about premature infants when it comes to nutritive sucking
inefficient pattern for 1month or more of life
How long is gastric motility delayed in an infant
the first few days
What are the birth weight categories of premature infants and their weights?
low birth weight: less than 2500 grams
very-low-birth-weight: less than 1500 grams
extremely-low-birth-weight: less than 1000 grams
micropreemies: less than 750 grams
What is the average birth weight for an infant
3500 grams
How much water weight is lost immediately after birth
6-10% of birth weight
How much should a term infant weigh at 4-6 months? 12 months?
should double birth weight by 4-6 months and triple it by 12 months
What are the basic requirements for a healthy diet
water
carbohydrates
proteins and amino acids
fat and essential fatty acids
micronutrients
How much water does the holliday-seger method estimate is needed for term infants
100mL/kg for the first 10 kg
50mL/kg for the second 10 kg
20mL/kg for every additional kg
How much maintenance water should premature infants be getting
120-170 mL/kg/day
For how long do human milk/formula = adequate daily water intake
the first 6 months of life
What percentage of the daily calorie intake is fulfilled by carbohydrates
40-50%
At what age should the child start consuming dietary fibers
at age 6-12 months, it is encouraged to get dietary fiber needs from whole cereals, green veggies, and legumes
Why does carbohydrate intake need to be balanced with fats
to ensure healthy neurological development
How much does the total body protein intake change in the first year of life for an infant
it increases from 11% to 15%
T or F: preterm infants have higher protein needs
True, their needs are not met by human milk and their diet needs fortification from commercial powders/liquids
Why is human breast milk so important for an infant to consume protein-wise?
the protein content changes with the growing infant to meet their needs. Formulas can not mimic this well
