Abstract: The largest study designed to ameliorate adverse effects of premature low birth weight
(LBW) and to prevent mental retardation is the Infant Health and Development Program
(IHDP). This was a randomized, multisite intervention: home visits for 3 years, parents
meetings, and intensive preschool education for 2 years. IHDP reported results alleging
the program significantly influenced intelligence and prevented mental retardation. We
conducted an independent analysis of the original computerized database (at 3 years).
Five-year follow-up data were obtained from the journal publication and from data on file
with the National Auxiliary Publication Service. Our intent was to determine the magnitude,
durability, and clinical significance of purported intervention effects and how these
are mediated. Methods used were primarily multivariate correlational analyses and examination
of the logic underlying the conclusions. Results suggest alternative interpretations
of claims regarding IHDP. Effects are explained by confounding variables, questionable
analytical procedures, distorted interpretations, and data inconsistencies. Effect sizes and
specificity of effect reported by IHDP do not survive scrutiny either in the original
database or at 5 years. Given the vastly complex nature of premature LBW, IHDP was
poorly conceived, failing to produce meaningful and enduring effects on IQ. Policy conclusions
for interventions with LBW infants stemming from IHDP are misleading.
