Objectives

• To recognize the changing nutritional needs of developing children, from infancy to adolescence.

• To understand the concept of malnutrition

• To understand the principles of pediatric nutrition care to prevent malnutrition

Pediatric stages development

• Neonates (0-1 month)

• Infancy (0-1 yr)

• Toddlerhood (1-2 yr) young children

• Preschool (3-5 yr)

• School age (6-9 yr)

• Adolescent (10-20 yr) – Early adolescence (10-13 yr)

– Middle adolescence (14-16 yr)

– Late adolescence (17-20 yr)

Growth and Development an essential feature of life of a child and

distinguishes him or her from an adult

• GROWTH is a process starts from the time of conception of the fertilized ovum (egg) and continuous until the child grows in to a fully mature adult.

• DEVELOPMENT is defined as maturation of functions.

Assessment of growth and development

• Growth parameters

Physical growth of a child is evaluated by body measurement

• body weight

• length or height

• Head

circumference

• Development parameters – Motor development

(physical development) • Gross motor skills • Fine motor skills

– Cognitive (language) development

• Receptive • Expressive

– Psychosocial development • Emotional • Social • Adaptive

Factors affecting growth and development

• Genetic factors – The tall parents

have tall children and so on.

– In girls growth spurt occurs earlier at puberty

• Environmental factors – Nutrition

– Chemicals : • food additives, etc

– Injury

– Infection

– Social Factors

– Emotional factors

– Cultural factors

Why is Nutrition Important?

• Energy of daily living

• Maintenance of all body functions

• Vital to growth and development

• Therapeutic benefits

– Healing

– Prevention

What are nutrients ?

• Macronutrients – Carbohydrates

– Protein

– Lipid

• Micronutrients – Vitamins

– Mineral

• Water

How much nutrients are needed for growth and development ???

Consequences of deficit/excess Malnutrition (Jelliffe,1966)

• Undernutrition

– Mild, moderate, severe malnutrition

• Overnutrition

– Overweight & obesity

• Specific nutrient deficiencies or imbalance

– Iron deficiency

– Iodine deficiency, etc

Severe malnutrition (marasmus & kwashiorkor)

Overnutrition

Iodine deficiencies

• Short stature

• Hernia umbilicalis

• IQ 13.5 point, mentally retarded, cretinism, myelinization

Iron deficiency anemia IQ 10-20 point

Hypervitaminosis D

80% mild-

moderate

20% severe

How big is the problems ??

What physician should do to prevent malnutrition ?

Health Care

Child Health Care

Optimizing the growth, development and well being of infants, children and adolescents.

Healthy

• Primary Prevention – Promotion of well

being aims to prevent the initial occurrence of an illness

– Optimalization growth & development

Sick

• Secondary Prevention – Early intervention aims

to stop or slow an existing illness by early detection and appropriate treatment

• Tertiary Prevention (Cure) – Diseases management

aims to reduce the re-occurrence and establishment of chronic illness

Principles of Pediatric Health Care

• Diagnostic

• Management – Drugs or Surgery

– Nursing Care • Ambulatory, Hospitalized:

intermediate care, ICU etc

– Nutrition Care – Rehabilitation Care

Assessment clinical & anthropometrics for individual nutritional status

• Z-score classification Wasting : Weight-for-height z-score (WHZ) <-2.00 – Moderate WHZ -3.00 to -2.01 – Severe WHZ <-3.00

• Weight(kg) for height (m2) (BMI for Age - CDC 2000) parameter overweight & obesity – <5th percentile underweight – 5th - <85th percentile normal variation – 85th - <95th percentile overweight – 95th percentile obese

• Percent ideal body weight (Olsen et al, 2003)

Classification

Percent of Ideal Body Weight (IBW)

• Percentage of the child’s actual weight compared to ideal weight for actual height (Goldbloom, 1997)

• IBW is determined from the CDC growth chart (Olsen et al, 2003)

– Plotting the child’s height for age

– Extending the line horizontally to the 50th percentile height-for-age line

– Extending the vertical line from the 50th percentile height for age to the corresponding 50th percentile weight, noting this as IBW

– Percent IBW is calculated as (actual weight divided by IBW) X 100%

IBW is used as a clinical weight goal in the nutrition rehabilitation

• Nutritional Status : – Actual weight/IBW (%)

• Classification of Percent of IBW (Waterlow, 1972)

– ≥120% obesity – ≥110 -120% overweight – ≥90-110% normal – ≥80-90% mild malnutrition – ≥70-80% moderate malnutrition – ≤70% severe malnutrition

Calculation of Catch-Up Growth requirement in the Pediatrics

• Indication – Children who are below normal growth

parameters due to chronic undernutrition or illness affecting their nutritional intake and status require additional calories and protein to achieve catch-up growth (nutritional support).

• Kcal = RDA (kcal/kg) for height age* x Ideal weight (kg)* – * Age at which actual height is at the 50th %-ile

** Ideal weight for actual height

Guidelines How to choose Type of Nutrition

• Patient Factors – Age (stage of

development) – Diagnosis associated

nutritional problems – Nutritional

requirements – Gastrointestinal

function

• Nutritional Factors – Osmolality (isotonic

150-250mOsm) – Renal solute load – Caloric density and

viscosity – Nutrient composition:

type & amount of CHO, Fat and protein

– Product availability and cost

Feeding the Infant / the Child

• What are the options?

– Breast feeding • The WHO recommends exclusive breast

feeding at least for 6 months.

– Formula feeding

– Complementary Feeding

– Family foods

5.Monitoring n Evaluation

Monitoring results of nutrition care

• Food acceptability, tolerance, efficacy

• Parameter : – Acceptability : like or dislike

– Tolerance : look for adverse food reaction

– Efficacy : growth monitoring

Assessment of sufficient breast feeding

• Weight pattern - consistent weight gain

trimester 1 : 25-30 g/d = 200 g/w = 750-900 g/mo

trimester 2 : 20 g/d = 150 g/w = 600 g/mo trimester 3 : 15 g/d = 100 g/w = 400 g/mo trimester 4 : 10 g/d = 50-75 g/w = 200-300 g/mon

• Voiding – 6-8 wet diapers/day, soaked not only wet • Stooling - generally more stools than formula. • Feed-on-demand ~ every 2-3 hours (8-12 times a

day). • Duration of feedings - generally 10-20 min/side. • Need for high fat hind milk. • Activity and vigor of infant.

Infant Feeding Practice

• Depend on :

– Maturation of neuromotoric system

– Maturation of gastrointestinal system

– Maturation of immunological system

Approximately Daily Weight Gain

• At 16 months the weight should be:

– 3 x 750 g = 2250 g

– 3 x 600 g = 1800 g

– 3 x 450 g = 1350 g

– 3 x 250 g = 750 g

– 4 x 160 g = 640 g 6790 g

Nutrition Care – Nutritional assessment

• Specific growth chart (-) CDC/NCHS 2000 • IBW for 65 cm 7.4 kg • Nutritional status 5/7.4 67.5% (severe

malnutrition) • Based on daily weight gain failure to thrive

– Nutritional requirements • Height age 5 month RDA 110 kcal/kg • Requirement 7.4 X 110 kcal = 814 kcal • Prevent refeeding syndrome begin 50%-75%

requirement 400--600 kcal gradually increased to 814 kcal

– Routes of delivery • Oral or enteral

– Formula selection • Hypoallergenic formula 400-600kcal/20 kcal/oz 20-

30 oz ± 600-900 mL/24 hours – Monitoring

• Diarrhea & vomitus (-) • Growth (BW, BL)

Nutrition Care Result

HA : 5 mos

IBW : 7.4 kg

25 months W : 10.7 kg L : 77 cm HA : 12 mos IBW : 10 kg

Refeeding Syndrome

• Metabolic complication associated with giving nutritional support (enteral or parenteral) to the severely malnourished

• Starved cells take up energy substrates – rapid fluxes in insulin production in

response to CHO load – hypophosphotemia and hypokalemia.

• Control by giving formula meeting 50-75% of need and advance gradually and monitoring electrolytes
