Evaluation of Regionalized Networks of High-Risk Pregnancy Care, 1970-1979 (ICPSR 8469)

Released/updated on: 2006-01-12

Geographic coverage: United States

Time period: 1970-01-01--1979-01-01

Data provided in this collection were gathered to evaluate the effectiveness of a five-year program demonstrating regionalization of perinatal health care for mothers and infants. There are three distinct types of data in the collection. The first consists of records of live births in eight program regions and eight comparison regions. Included in these records are data on the size and type of institution of birth, birthweight, number of previous births and pregnancies, gestational age, and method of delivery. Also provided are demographic data such as age, race, educational level, and marital status of the mother. The unit of analysis is the live birth. The second type of data in the collection consists of matched birth and death data for infants, using the same geographical coverage as the live birth data. Each record contains the data provided in the live birth data, plus information such as the place of death, age at death, and cause of death. The unit of analysis is infant deaths for which birth data are available. The third type of data are derived from a survey of infant health at one year of age. Included in this are data on employment, education, and previous pregnancies of the mother, plus information on pre- and post-natal hospitalization, medical care, and infant health. Additional data are provided for a test, administered to each infant, of adaptive, gross and fine motor, and receptive language development.

Infant Health and Development Program, Phase IV, 2001-2004 [United States] (ICPSR 23580)

Released/updated on: 2013-02-15

Geographic coverage: United States

Time period: 1984-01-01--2004-01-01

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.
