The recognition of expansion and developmental problems in infants and children is single of the major challenges facing primary care physicians. Failure to thrive (FTT) is a customary condition of varying etiologies that has been associated with adverse meanings on later growth and cognitive evolution (1,2) Primary care physicians ne to be able to diagnose and manage FTT promptly to resolve into the risk of long-term sequelae.

Definition

FTT is best defined as inadequate physical sprouting diagnosed by observation of increase over time using a standard extension chart. The National Center for Health Statistics (NCHS) newly released improved growth charts that can be raise at www.cdc.gov. While definitions of FTT have varied, greatest in quantity practitioners diagnose FTT when a child's weight for age falls below the fifth percentile of the standard NCH pullulation chart or if it crosse sum of two units major percentile lines. (3) latter research has validated that the weight-for-age approach is the simplest and greatest in quantity reasonable marker for FTT. (4) Other bourgeoning parameters that can assist in making the diagnosis of FTT are weight for height and height for age. FTT is diagnosed if a child falls below the 10th percentile for either of these measurements.

Etiology and Differential Diagnosis

Historically, FTT has been classified as organic or nonorganic. Usually, this distinction is not useful because chiefly children have mixed etiologies. (5) For example, a child may have a medical disorder that causes feeding puzzles and family stress. The stres can combine the feeding problem and aggravate FTT A more useful classification classification is based on pathophysiology--inadequate caloric intake, inadequate absorption, exces metabolic demand, or defective utilization. This classification leads to a logical organization of the many conditions that cause or contribute to FTT (Table 1)

Stres and other psychosocial factors many times contribute to FTT. For example, a bring lowed mother may not feed her infant adequately. The infant may become withdrawn, responding to the mother's depression, and fe les well. Another example is when parents are overly anxious about a child's feeding. Coercive practices can lead to feeding behavior question s and FTT.

shooting variation in normal infants can embarrass the diagnosis of FTT. Approximately 25 percent of children will shift down their weight or height at more than 25 percentile points in the first sum of two units years of life. (6) These children are falling to their genetic potential or demonstrating constitutional shooting delay (slow growth with a bone age les than chronologic age). After shifting down, these infants increase at a normal rate along their strange percentile and do not have FTT

Specific infant populations with bourgeoning variations also need to be considered when making the diagnosis of FTT Infants who have had intrauterine development retardation or premature infants may appear to have FTT when they wax at less than the fifth percentile. As prolonged as the child is growing along a bend with a normal interval development rate, FTT should not be diagnosed. (7) In addition, using modified increase charts for specific populations, like as premature infants, (8) exclusively breastfed infants, specific ethnicities (eg Asian), and infants with genetic syndrome (eg Down syndrome) (9) can help reassure the physician that these children are growing appropriately.

Evaluation

RECOGNIZING FTT

The elucidation to diagnosing FTT is finding the time in busy clinical practice to accurately measure and draught a child's weight, height, and head circumference, and then assess the tendency One study (10) from England demonstrated that 54 percent of general practitioners had not diagnosed FTT although a child's weight for age ferocious below two major percentile lines. In addition, a pilot subject of attention (11) performed at a family practice residency clinic institute that of 29 children diagnosed with FTT 100 percent of the charts contained measurements that were incorrectly plott The diagnosis was delayed in 41 percent of the patients.

HISTORY

After determining that FTT is a belong to the evaluation should focus upon a careful history, including an assessment of diet and feeding or eating behaviors, and past and generally received medical, social, and family history. Table 2 details items that should be overlayed in each category.

It is important to ascertain the child's developmental status at the time of diagnosis because children with FTT have a higher incidence of developmental delays than the general population. (12) Physicians should still be belong toed about a child without developmental delays who is failing to thrive. FTT is primarily a pullulation disorder, not a developmental problem

PHYSICAL EXAMINATION

A completed physical examination is essential, with four main goals: (1) identification of dysmorphic features suggestive of a genetic disorder impeding growth; (2) detection of underlying disease that may impair growth; (3) assessment for signs of possible child abuse; and (4) assessment of the severity and possible purports of malnutrition. (12,13) The severity of a child's undernutrition can be determined most numerous easily by using the Gomez criteria. on comparing the child's current weight for age with the anticipateed weight (50th percentile) at that age, the step of malnutrition can be assessed. If the weight is les than 60 percent of awaited the FTT is considered rigorous 61 to 75 percent denotes moderate FTT and 76 to 90 percent is mild. (14)
