WHO <24 months
CDC >24 months
Why use the WHO growth charts?
- for <24mo
- Growth of BF infant is standard
- Better description of physiological growth in infancy
- Based on high quality study aimed at developing growth charts
What is stunting?
Low height for age (2 SD)
When does stunting start?
•before birth ( poor maternal nutrition)
Why does stunting occur?
- Before birth: poor maternal nutrition
- Poor feeding practices
- Poor food quality
- Frequent infection (–> slowed growth)
What is wasting?
Low Weight for Height
by 2 SD
Definition of underweight
Low Weight for Age
Major contributor to under-five deaths?
Undernutrition
Interventions to prevent undernutrition?
- Breast feeding within one hour of birth
- Exclusive breast feeding through 6 mos
- Adequate complementary feeding
- Micronutrient supplements
Why is breastfeeding recommended?
- Bonding
- Nutritional value
- Availability
- Different effects on metabolism
- Self regulation
- More open to variety of tastes (formula always tastes the same, BM flavor varies w/mom’s diet)
Why is formula used?
As a substitute for human milk
How is formula regulated in the U.S.?

•Rationale
–Meet hgb needs after maternal stores depleted (RBCs last 120 days - after 4 months needs restoring)
–Increase stores prior to whole cow’s milk: Prevent IDA
–Improve alertness, ability to interact and learn
Iron absorption from breast milk vs formula?
- 50% of iron absorbed from breast milk
- 12% of iron absorbed from formula
How much iron in iron fortified formulas?
- Iron fortified formulas contain 10-12 mg/l
- Low iron formulas discontinued (were used for fussy babies - no evidence and deprives of needed Fe)
Formula recommendations for non-breast fed term healthy babies?
–Start on CM formula at 20cal/oz
–Iron-fortified formula
–0-12 mos
What is DHA/ARA and why is it being added to formulas?
newer ingredients
•DHA(Omega-3)/ARA (Arachidonic acid)
–Structural fats found in brain and retina
–Better cognitive and visual development (until 18 months)
–Now all formulas fortified
Why are prebiotics being added to formula?
to help develop the immune system
Rationale for avoiding palm oil in formula?
Improved calcium absorption w/o palm oil
