IOM guidelines: Background
Excess weight gain during infancy is a significant risk factor for later obesity
For American children from low-income minority families, excessive weight gain in the first year of life
has been associated with a nine-fold increased risk for obesity at age 3 years
Infant feeding - IOMs infancy-related guidelines for the prevention of childhood obesity
encourage exclusive breastfeeding in teh first 6 months and continuation of breastfeeding with the
introduction of solid foods during the second half of infancy
Help parents recognize and respond to infant hunger and fullness cues (sucking on fist, waking and
tossing, opening mouth while feeding to indicate wanting more), satiety or fullness behaviors indicated
turning head away, sealing lips, and decreased or stopping sucking
longer breastfeeding = reduced risk for later obesity
recommend that health care providers encourage infant feeing behavior that is responsive to hunger
and satiety cues
weight gain may depend on not only milk consumed but also type of milk delivery
IOM guidelines: infant sleep
,shorter sleep duration correlated with higher infant weight for length ratios
infant sleep less than 12h/d associated with higher BMI and increased odds of overweight at 3 years of
age
Encouraging sleep-promoting behaviors, such as calming routines at bedtime, self-regulation of sleep by
putting to sleep drowsy but awake
mothers taught alternative strategies to feeding as a first response to nocturnal crying and fussiness,
learned to distinguish these cues from other causes of infant distress such as boredom, anger, or
discomfort of a soiled diaper
multi-component behavioral interventions may be required to effectively overcome the rapid weight
gain in infancy that places children at risk for long term obesity
IOM guidelines - infant physical activity
calls for more daily opportunity for infants to move freely both indoors and outdoors, spend time on teh
ground engaging in adult-infant interactions, and for babies under 6 months of age to experience more
"tummy time"
Limit long term use of confining baby equipment such as car seats, strollers, bouncer seats and playpens
prone positioning predicted the acquisition of three age dependent
another study found frequency of gross motor delays was significantly higher among infants whose
weights-for-length ratios were between the 85 and 94th percentiles
Gross motor developmental delays among overweight infants and those with high subcutaneous fat may
lead to a cascade of increased risk for reduced physical activity and limited exploration of the
environment
Key features of breast milk and infant formula: abstract
breast milk as a biologic fluid has a variety of other benefits, including modulation of postnatal intestinal
function, immune ontogeny, and brain development. Although breastfeeding is highly recommended,
breastfeeding may not always be possible, suitable or solely adequate. Infant formula is an industrially
produced substitute for infant consumption. Infant formula attempts to mimic the nutritional
composition of breast milk as closely as possible, and is based on cow's milk or soymilk. A number of
alternatives to cow's milk-based formula also exist.
, Human breast milk
Human breast milk contains carbohydrates, protein, fat, vitamins, minerals, digestive enzymes and
hormones. In addition to these nutrients, it is rich in immune cells, including macrophages, stem cells,
and numerous other bioactive molecules. Some of these bioactive molecules are protein-derived and
lipid-derived, while others are protein-derived and indigestible, such as oligosaccharides. Human milk
oligosaccharides (HMOs) possess anti-infective properties against pathogens in the infant
gastrointestinal tract, such as Salmonella, Listeria, and Campylobacter, by flooding the infant
gastrointestinal tract with decoys that bind the pathogens and keep them off the intestinal wall.
Oligosaccharides also play a vital role in the development of a diverse and balanced microbiota,
essential for appropriate innate and adaptive immune responses, and help colonize up to 90% of the
infant biome
Human milk options - milk donors and milk banks
The World Health Organization and the American Academy of Pediatrics recommends pasteurized
human donor milk for preterm infants when a mother's own milk is unavailable. Donor milk undergoes a
pasteurization process, which reduces many of the normal commensal microbes, as well as significantly
reducing or obliterating live immune cells, bioactive proteins, and enzymes, collectively limiting some of
the health benefit compared to a mother's own milk. Research efforts to optimize donor breast milk are
ongoing. Before using donor breast milk, the mother should consult with their baby's health care
providers.
Infant formulas
Infant formula is intended as an effective substitute to breast milk and is formulated to mimic the
nutritional composition of breast milk. The recently updated FDA (Food and Drug Administration) rule
on current Good Manufacturing Practices for infant formula, 21 CFR 106.96, requires, among other
things, that formulas satisfy the quality factors of normal physical growth and a sufficient biological
quality of protein component (adequate amounts of protein in a form that can be used by infants).
Infant formula is only for the health of infants without unusual medical or dietary problems. The
manufacturing process is highly regulated and monitored to meet national and international quality
criteria
Non-bovine milk sources
Elimination of all cow milk products without appropriately modified and fortified substitutions can lead
to malnutrition and/or specific nutrient deficiencies at a time when infants and children are growing.
