Feeding growth

Feeding & Growth


Breastfeeding

Breastfeeding

  • CPS recommends exclusive breastfeeding for babies up to 6 months (when possible)

  • Breast milk has a caloric content of

    ~20 Kcal/oz (0.67 Kcal/ml)

  • Babies need 100-130 Kcal/Kg/day in 1st 3 months

  • Feeding/growth spurts occur at 8-12 days, 3-4 wks, 3 mo, variably after that


When comparing human breastmilk and cow s milk the following is correct

When comparing human breastmilk and cow’s milk the following is correct

  • The ratio of whey:casein is higher in human milk

  • Cow’s milk has a lower solute load

  • Human milk has higher iron content

  • Cow’s milk has lactose, human milk does not

  • Human milk has sufficient vit D


Nutritionally how does breast milk compare to cow s milk

Nutritionally, how does breast milk compare to cow’s milk?

  • Lower protein content - decreased solute load

  • Greater whey:casein (70/30 vs 18/82, formula 60/40)

  • CHO - both are lactose based (6.5% vs 4.5%)

  • Fat - 30-50% vs 3.5-4%

  • Vitamins - richer in A,C,E, lower in D & K

  • Minerals - lower Fe but better absorbed


Breast feeding benefits for baby

Breast Feeding Benefits for Baby

  • Immunological benefit

    • secretory IgA, lactoferrin, lysozyme as GI defence

    • Lower rate OM, LRTI, gastro, possibly UTIs, Hib

  • Less allergenic

  • Less constipating

  • Better jaw/mandible development

  • Attachment and ?Improved cognitive functioning


Breast feeding benefits for mother

Breast Feeding Benefits for Mother

  • Postpartum weight loss & uterine involution

  • Delayed return of fertility

  • Bonding

  • Pre-menopausal breast & ovarian Ca reduced

  • Economical benefit


Breast feeding issues

Breast Feeding Issues

  • Takes 3-7 days for milk supply to come in

    • risk of dehydration/ “breastfeeding jaundice”

  • Jaundice is more common

    • Breastmilk jaundice

  • “Mom/baby team”

    • ineffective latch/sore nipples/engorgement

  • Infections

    • thrush , mastitis/abscess

  • Reduced levels vitamin D & K


Vitamin d supplementation

Vitamin D Supplementation

  • Rickets is still a problem in Canada!

  • 400 IU per day

    • All Breastfed infants

    • Pregnant and nursing mothers in northern Canada

    • Formula Fed infants living in northern Canada

  • 800 IU per day - < 2 yrs breastfed babies with a risk factor

    • Home above 55 degree latitude, darker skin, sun avoidance

    • Community with high prevalence Vit D deficiency

  • Vitamin D is found in milk, margarine, salmon, tuna, liver, kidney & from the sun


  • Contraindications to breast feeding

    Contraindications to Breast Feeding

    • Maternal infections

      • HIV, AIDS, active TB, malaria, herpes on breast, hepatitis

    • Maternal sepsis

    • Psychotropic meds or others crossing

    • Chemo/radiation

    • Alcohol/drug abuse

    • Infant Galactosemia (lactose)

    • *May breastfeed even with VZV


    Cow s milk formula

    Cow’s Milk Formula

    • Always Fe fortified

    • Many choices!

    • Specialty formulas

      • soy, lactose free, increased calories

      • Protein hydrolysate formulas

        (eg.Alimentum, Nutramigen, Progestemil)

      • Amino-acid based formulas (Neocate)


    Introduction of solids

    Introduction of Solids

    • cereals 4-6 months

    • vegetables

    • fruits

    • meats

    • cow’s milk should be postponed until at least 10-12 months of age (renal load)

    • 2% or 1% milk should be postponed until after second birthday (inadequate fat content)

    Rest gradually in this order


    Infant growth rules of thumb

    Infant Growth: Rules of Thumb

    • Weight gain:

      • Regain birth weight by 10-14 days (max 10% loss)

      • Double birth weight by 5 months

      • Triple birth weight by 1 year

      • Quadruple birth weight by 2 years

      • Increase by 5 lbs/year for rest of childhood


    Growth height

    Growth - Height

    • Average length at birth 50 cm (20 inches)

    • Increases by 50% by 1 yr

    • Doubles by 4 yrs

    • Triples by 13 yrs

    • Ave growth 5-6 cm / yr (4 yrs-puberty)


    Growth body mass index bmi

    Growth- Body Mass Index (BMI)

    • BMI helps to quantify the weight to height relationship

    • BMI = weight(kg)/height (m)2

    • BMI of 20-25 is acceptable

    • BMI > 30 indicates obesity

    • BMI < 18 suggest severe anorexia or Failure to thrive


    Growth head circumference

    Growth- Head Circumference

    • 2 cm/month 1-3 months

    • 1cm/month 3-6 months

    • 0.5cm/month 6-12 months

    • Most of growth is in first yr!

    • 12 cm in first yr, 2 cm in 2nd yr, 6-8 cm rest of life


    Growth monitoring

    Growth Monitoring

    • Routinely recommended

      • Height, weight, head circumference

      • Plot on appropriate chart considering ethnicity, genetic syndromes (eg. Tri 21, Turner’s), and prematurity

      • Prematurity, correct hc (18 mo), wt (24 mo),

        ht (40 mo)

    • Only way to detect FTT

      • Also detects chronic illness, feeding difficulties


    What is failure to thrive

    What is Failure to Thrive?

    • US National Center for Health Statistics defines FTT for children < 2 yrs of age as:

      • Weight <3rd-5th centile for age on more than one occasion

      • Weight <80% of ideal body weight for age

      • Weight crosses 2 major centile curves downwards on a standardized growth curve

      • Exceptions: genetic/familial short stature, constitutional growth delay, SGA infants & preterm infants


    Caloric needs

    Caloric needs

    • 0-10 kg: 100 kcal/kg/day

    • 10-20 kg: 1000 + 50 kcal/kg/day

    • >20 kg: 1500 + 20 kcal/kg/day


    Which growth curve demonstrates a growth pattern of ftt

    Which growth curve demonstrates a growth pattern of FTT?

    • A

    • B

    • C


    Which growth curve demonstrates a pattern of genetic short stature

    Which growth curve demonstrates a pattern of genetic short stature?

    • A

    • B

    • C


    Ftt infant growth

    FTT- Infant Growth

    • Caveats to normal growth velocity:

      • >50% of babies shift their growth parameters upwards between birth and 3 months

      • Nearly 30% of well babies shift their parameters downwards between 3 and 18 months

      • Exclusively breastfed babies plot higher for wt at 0-6 months and lower at 6-12 months5


    Growth velocity

    Growth Velocity

    • Average age to “settle” on a growth curve is 13 months6

    • Downward shift seen with constitutional growth delay

      • downward shift between 6 & 24 months

      • may have decreased weight for height

      • re-establish normal growth velocities by 3 yrs

        *Genetically Programmed curve is established by 18-24 months


    Ftt assessment

    FTT- Assessment

    • Grading of malnutrition:


    Ftt assessment1

    FTT- Assessment

    • “Organic” vs. “non-organic”

      • Historical way of viewing FTT

      • Refers to presence/absence of diagnosis of major disease process or organ dysfunction

      • “Non-organic” accounts for >80%

      • Now felt to be more of a continuum

      • Multifactorial process


    Ftt assessment2

    FTT- Assessment

    • Under-nutrition results from:

      1)Decreased caloric intake

      2) Inadequate caloric absorption

      3)Increased caloric losses

      4)Increased caloric requirements


    Ftt differential diagnosis

    FTT- Differential Diagnosis

    • Decreased caloric intake:

      • Inadvertent (decreased breast milk, improper formula preparation)

      • Neglect or abuse

      • Behavioural (ex. Food refusal)

      • Pain (GERD, injury to mouth or esophagus)

      • Fatigue /anorexia (anemia, cardiac dz, resp dz, RTA)

      • Impaired swallowing (neurologic dz)

      • Craniofacial abnormalities (cleft lip/palate, choanal atresia)

      • Toxin (lead)


    Ftt differential diagnosis1

    FTT- Differential Diagnosis

    • Inadequate Caloric Absorption & Increased Caloric Losses

      • GI

        • Pancreatic insufficiency (CF)

        • Liver disease (biliary atresia, chronic cholestasis)

        • Generalized malabsorption (CF, Celiac, short gut)

        • Diarrheal state (infectious, post-infectious)

        • Persistent vomiting (pyloric stenosis, GERD)

        • Inflammatory disorders (IBD)

        • Allergic gastroenteropathy

        • Protein-losing enteropathy


    Ftt differential diagnosis2

    FTT- Differential Diagnosis

    • Increased Caloric Losses cont’d

      • Renal

        • Protein loss

        • Carbohydrate loss

      • Inability to use nutrients

        • Diabetes Mellitus

        • Metabolic dz


    Ftt investigations

    FTT- Investigations

    • Careful and complete history taking and physical examination are ESSENTIAL

    • Unless an illness other than primary under-nutrition is suspected on Hx or P/E the yield of lab investigations is almost nil!

    • Lab testing helps with diagnosis in 1.4%


    Ftt investigations1

    FTT- Investigations

    • Non-specific “screening”

      • CBCD, ESR, lytes, BUN, Cr, venous gas

      • Urine R&M, C&S

    • Markers of nutritional status

      • Total protein, albumin, glu, Ca, PO4, Iron studies

      • Zinc, vitamin levels

    • Dependent on specific aspects of Hx & P/E

      • Liver function tests

      • Thyroid studies

      • Stool OB, reducing substances, culture, O&P, trypsin

      • Sweat test, immunoglobulins & celiac screen, viral serology (incl HIV), TB testing, immune w/up, metabolic w/up, CXR, ECG, milk scan


    Ftt management

    FTT- Management

    • Admit if :

      • Suspect enviro. deprivation/neglect/abuse

      • Suspect chronic dz which needs stabilizing

      • Severe under-nutrition (consider if moderate)

        • ie. <60% of median weight for age

      • Failed out-patient management

    • With hospitalization:

      • greater likelihood of catch-up growth

      • no change in developmental outcomes


    Ftt management1

    FTT- Management

    • Inter-disciplinary approach!!

    • Treat any underlying illness and provide nutritional support:

      • Increase caloric intake

        • 1.5-2 X RDA

        • (120 kcal/kg/day x ideal wt)/current wt

        • Estimate 150-200 kcal/kg/day


    Ftt management2

    FTT- Management

    • Mild under-nutrition

      • Ensure frequent feedings (q 3 hrs)

      • Increase formula concentration (eg. 24 kcal/oz)

      • Add calorie-rich foods to diet (butter, PB, oils)

      • Provide dietary counseling

      • Prescribe multivitamin with zinc and iron

      • Follow-up frequently (?public health nurse)

      • Expect catch-up growth at 2-3x regular rate in first month


    Ftt management3

    FTT- Management

    • Moderate under-nutrition

      • Determine caloric intake

      • Consider whether investigations are necessary

      • Increase caloric intake (150-200 kcal/kg/day)

      • Ensure adequate protein (3-4 g/kg/day)

      • Consider meal supplements (eg. Pediasure)

      • Add Multivitamin

      • Consider therapeutic doses of iron

      • Monitor weight gain


    Ftt management4

    FTT- Management

    • Severe under-nutrition

      • Admit

      • Initiate re-feeding slowly

      • Consider using elemental formula

      • Consider diluting formula

      • May need ng continuous feeds or tpn

      • Follow fluid and lytes status closely


    Ftt long term implications

    FTT- Long-term implications
