About this Collection

The Infant Health and Development Program (IHDP) was a multisite, randomized, controlled trial of an educational intervention until three years of age for low birth weight preterm infants born in 1984-1985. There were three components to the intervention: (1) an educational program delivered through home visits (weekly during the first year and every other week during the second and third years of life), (2) a daily center-based program beginning at 12 months corrected for duration of gestation, and (3) parent support groups coinciding with the start of the center-based program.

Information about the variables available in each data collection, as well as related publications specific to that collection, is available at the individual study homepages.

Infant Health and Development Program (IHDP): Enhancing the Outcomes of Low Birth Weight, Premature Infants in the United States, 1985-1988

The Infant Health and Development Program was a collaborative, randomized, longitudinal, multisite clinical trial designed to evaluate the efficacy of comprehensive early intervention in reducing the developmental and health problems of low birth weight, premature infants. An intensive intervention extending from hospital discharge to 36 months corrected age was administered between 1985 and 1988 at eight different sites. The study sample of infants was stratified by birth weight (2,000 grams or less, 2,001-2,500 grams) and randomized to the Intervention Group or the Follow-Up Group. The Intervention Group received home visits, attendance at a special child development center, and pediatric follow-up. The Follow-Up Group received only the pediatric follow-up component of the program. Measures of cognitive development, behavioral status, health status, and other variables were collected from both groups at predetermined time points. Cognitive development was assessed by the Stanford-Binet Intelligence Scale, the Bayley Mental and Motor Scales, the Peabody Picture Vocabulary Test--Revised, and the Beery-Buktenica Developmental Test of Visual Motor Integration. Behavior problems were measured using the Richman-Graham Behavior Checklist and Achenbach's Child Behavior Checklist. Health status was evaluated through the dimensions of morbidity (defined as the presence or absence of health conditions), functional status (defined by limitations in activities of daily living due to health problems), changes in physical growth, and maternal perception of the child's health. The many other variables and indices in the data collection include site, pregnancy complications, child's birth weight and gestation age, birth order, child's gender, household composition, day care arrangements, source of health care, quality of the home environment, parents' race and ethnicity, and maternal age, education, IQ, and employment.

Infant Health and Development Program, Phase IV, 2001-2004 [United States]

The Infant Health and Development Program (IHDP) was a multisite, randomized, controlled trial of an educational intervention until three years of age for low birth weight preterm infants born in 1984-1985. There were three components to the intervention: (1) an educational program delivered through home visits (weekly during the first year and every other week during the second and third years of life), (2) a daily center-based program beginning at 12 months corrected for duration of gestation, and (3) parent support groups coinciding with the start of the center-based program. Previously, the subjects were assessed at baseline up to age 3 (Phase I), age 5 (Phase II), and age 8 (Phase III). Phase IV assessed them at age 18.

This data collection contains selected variables from all four phases that were used in analyses reported in two articles by the principal investigators and others:

As such, the collection comprises only some of the variables that were collected for Phase IV and the other phases.

The collection contains information about the children and their mothers/caregivers. Data on the children include treatment group, sex, birth weight group, and an index of neonatal health, plus indices of receptive vocabulary, intelligence, and adult-child activities at age 5, indices of intelligence, receptive vocabulary, reading ability, math ability, and behavioural problems and competencies at ages 8 and 18, and indices of risk behaviors, physical health, future expectations, and engagement towards school at age 18. Information about the mothers/caregivers includes maternal age and mother's race, as well as educational achievement at baseline and ages 5, 8, and 18; smoking at ages 5 and 18; measures of employment, physical health, and mental health at ages 5, 8, and 18; indices of parenting style, educational aspirations for the child, and yelling frequency at the child at ages 8 and 18; and indices of connectedness to the community and involvement with the child's school at age 18. Other variables include measures of home literacy and the presence of televisions in the household at age 5, and indices of family cohesion and conflict at ages 8 and 18.
