FTT is a common sign and remains diagnostic and therapeutic challenge. 10% of children in primary care settings show signs of failure to thrive FTT accounts for 1-5% of pediatric hospital admissions
The Diseases of Infancy and Childhood by L. Emmett Holt in 1897- reference to an infant who "ceased to thrive“. “Fail to thrive" first in 1933 in 10 th edition. 1967- psychosocial aspects of failure to thrive became synonymous with maternal deprivation syndrome /parental" deprivation syndrome DSM-III as "reactive attachment disorder
Term infants: Lose 5-10% of birth wt, regain by 10-14 days. Infants wt gain pattern: 1 kg/mo for the first 3 months 0.5 kg/mo from age 3-6 months 0.33 kg/mo from age 6-9 months 0.25 kg/mo from age 9-12 months Double the birth weight by 4-5 mo Triple the birth weight by 1 yr of age
Term infants : 1 st 3 months gain 25-30 g/day 3- 6 months gain 15-20 g/day 6months to 1 year of age, 12g/day 0.25 kg/mo until toddler 2 kg/y through early school age. Growth of Length : 25 cm in first 1 yr 12.5 cm in 2 nd yr 5-6 cm between 4yrs and puberty onset upto 12 cm at onset of puberty
Head Circumference : Average at birth 35cm 47 cm by age 1 year, rate then slows Average of 55 cm by age 6 years Caloric Requirements: 100-110 kcal/kg/d for the first half year 100 kcal/kg/d for the second half of the first year Beyond 10 kg, 50 kcal/kg/d is required until 20 kg Beyond 20 kg, 20 kcal/kg/d are necessary. Premature infant usually require 120-140 kcal/kg/day prior to 40 wks gestation.
Sign of unexplained weight loss or poor weight gain in a child or infant. 1. A child younger than 2 years of age whose weight is less than the 3 rd or 5 th percentile for age on > 1 occasion. 2. A child younger than 2 years of age with weight is less than 80% of the ideal weight for age. 3. A child younger than 2 years whose weight for age percentile crosses two major percentiles lines on a standard weight curves below a previously established growth rate.
Weight for Length: weight-for-length < 80% of ideal weight - Actual weight <70% of predicted weight-for-length requires urgent attention Weight for age decreases early in the course of FTT, followed by height.
child with genetically short stature, SGA infants, Preterm infants, and “over-weight” infants, whose height gain exceeds weight gain. Preterm infants : Plot using corrected age until 2 yrs of age if birth wt >1000gm until 3 yrs of age if birth wt < 1000gm Catch up growth for Primi: 18 mns for Head circumference 24mns for weight 40 mns for height
Historically : Organic and Nonorganic Organic FTT: underling major disease process Non organic FTT / Psychosocial FTT: environmental or social factors, no medical problem not mutually exclusive false dichotomy. Mixed may be present when the effects of organic disease are combined with concurrent psychosocial problems. FTT is a spectrum, with purely organic and purely environmental being the extremes.
National Center for Health Statistics (NCHS) developed growth charts in 1977. 2000 CDC growth charts represent the revised version of the 1977 Data from National Health and Nutrition Examination Survey (NHANES) is used to revise the charts.
Infants, birth to 36 months Weight-for-age Length-for-age Weight-for-length Head circumference-for-age Children and adolescents, 2 to 20 years Weight-for-age Stature-for-age Body mass index-for-age
Prevalence depends on population sampled. 5-10% of primis and children living in poverty in developed nations. Developing nations with high rates of malnutrition and or HIV infection. Nonorganic FTT is far more common in USA and other industrialized countries.
GOLDEN RULE :Comprehensive History and Physical Exam Prenatal events : Medical complications of pregnancy, IUGR Alcohol, smoking Mother’s emotional reaction to the pregnancy. Birth history and nursery course
Details of breast/ formula feeding Typical feeding schedule, plus food preparation (formula prep, portion size) Methods of feeding, length of time spent feeding, and diet supplementation/medication Description of type of solid foods taken (quantitative composition and frequency of meals and snacks) Prospective 3-day food diary A direct observation- issues of sucking ability, choking, regurgitation, vomiting, and diarrhea, mother’s affect and attitude. Change in formula, change from breast milk to formula, and changes in the primary individuals responsible for feeding the child Parents’ attitude about feeding (restrictions of food based on finances, religion
Medical history and review of systems may reveal existing or undiagnosed conditions Spitting/vomitting/food refusal Diarrhea/fatty stools Snoring/mouth breathing/enlarged tonsils Recurrent wheezing/pneumonias Recurrent infections Travel to/ from developing countries
Family composition Any major events in the child’s life Family stressors Chronic Illness, Martial stress Single parenthood Depression Domestic violence Substance abuse, Employment / financial obligations. Growth and eating pattern of other siblings Young parental age Affluent circumstances or parents engaged in career development Child rearing beliefs
Family history stature and growth patterns Medical problems Genetic diseases Developmental delays Developmental History of the child
Measure head circumference, weight, and length Analyze previous growth curves loss of subcutaneous fat &muscle mass wasted buttocks
Untreated impetigo Uncut/dirty fingernails Delays in social and speech development Lack of eye contact Expressionless face Hypotonia Edema /ascites Thin extremities Hepatomegaly Heart murmur Skin changes Signs of vitamin deficiency Hair changes
Mostly inconclusive Guided by history and physical exam CBC (Anemia) BMP with Mg (RTA/ metabolic disorders) U/A (Renal / Metabolic ) Lead level TFT ESR/CRP (sign of inflammation/infection
Stool - fat, pH, reducing substances, occult blood, ova and parasites, sweat chloride, TB and HIV Celiac Panel Bone age (familial short stature vs endocrine/nutritional ) Skeletal survey in < 2yr old with ? Physical abuse Urine –organic and amino acids Food allergy assessment
Organic FTT : Determine and treat the underlying cause Non-organic FTT : Hospitalize Sustained catch up growth (>30g/day ) Educate parents Multidisciplinary approach (Nutritionist, social worker, pediatrician) ACS.
Monitor I/O’s, Daily weight Monitor feeding technique Age appropriate 150 Kcal/Kg (ideal wt) per 24hr Fortify the formula High calorie foods (peanut butter, whole milk, dried foods)
Adding iron and Vitamin D, zinc Family centered approach Reinforce positive behavior Solid foods should be offered before liquids Minimize environmental distractions High calorie supplementation –Duocal,Polycose, Carnation Instant Breakfast, Formulas > 20cal/oz (Pediasure, Ensure, Resource)
Observation during non feeding times : level of nurturing and responsiveness of the parent degree to which the child seeks the parent in times of need, amount of time parent cuddles/holds baby
Severe malnutrition hypothermia, Bradycardia /hypotension Further diagnostic/ lab workup If abuse or neglect is suspected Lack of catch-up growth following outpatient management. Evaluating parent-child feeding interaction.
FTT in 1 st yr- ominous 1/3 with psychosocial FTT – developmental delay, social, emotional problems Organic FTT- variable, depends on cause and severity of FTT Need ongoing monitoring of cognitive and emotional development
FTT is a common sign which poses diagnostic and therapeutic challenge to pediatricians. Monitor growth patterns of children Good history and physical exam are the key for diagnosis Address both organic and nonorganic causes for any child with FTT Needs Multidisciplinary approach for management

You are working in the emergency department when a mother brings in her 8-month-old son. She is concerned because he has had diarrhea for 2 months that has worsened over the last day. She explains that the stool is greasy, but there is no blood. He has had two episodes of sinusitis but no hospitalizations. They are new to town and he has not seen a physician since his 2-month health supervision visit. On physical examination, the boy appears pale, cachectic, and mildly dehydrated but alert. He has nasal congestion, his lungs are clear, and findings on his abdominal examination are normal. His weight is below the 5th percentile, length is at the 10th percentile, and head circumference is at the 25th percentile. He has a foul- smelling, greasy stool in his diaper. Of the following, the test MOST likely to reveal the diagnosis is
A. enzyme-linked immunosorbent assay for Giardia B. serology for antigliadin antibodies C. stool evaluation for alpha-1-antitrypsin D. stool evaluation for ova, cysts, and parasites E. sweat test
