“…* * * Failure to thrive (FTT) is a common problem of infancy and early childhood, estimated to affect 1-5% of hospitalized children (Berwick, 1980;Hannaway, 1976), 5 -10% of children seen in outpatient clinics (Altemeier, O'Connor, Sherrod, Yeager, & Vietze, 1985), 1.8% of infants in British inner cities (Skuse, Gill, Reilly, Wolke, & Lynch, 1995) and 10% of children living below the level of poverty in rural and urban American settings (e.g., Massachusetts; Geyer, Wehler, & Anderka, 1985). Although there is still much controversy surrounding its definition (Benoit, 1993a(Benoit, , 1993bMaggioni & Lifshitz, 1995), FTT is generally viewed as a syndrome characterized by: (1) weight-for-age at or below the fifth percentile on standardized growth charts, (2) weight less than expected for height, and (3) a deceleration in the rate of weight gain from birth to the present (weight decrease of at least two standard deviations on growth charts) (Altemeier, Vietze, Sherrod, Sandler, Falsey, & O'Connor, 1979;Benoit, Zeanah, & Barton, 1989;Drotar & Eckerle, 1989;Gorman, Leifer, & Grossman, 1993). In addition, FTT has been associated with varying degrees of developmental and medical sequelae (Bithoney & Rathbun, 1983;Drotar, 1991;Drotar & Sturm, 1987;Heffer & Kelley, 1994;Oates, Peacok, & Forrest, 1985;Pollitt, 1987;Pollitt et al, 1996;Puckering et al, 1995;Raynor & Rudolf, 1996;Reif, Beler, Villa, & Spirer, 1995;Singer, Drotar, Fagan, Devost, & Lake, 1983).…”
