Influence of Early Health Morbidity and Environmental Risk Factors on the Cognitive Functioning of Young School Age Children Ph.D. Dissertation, Johns Hopkins University, 1992 Cohort(s): Children of the NLSY79, NLSY79 Publisher: UMI - University Microfilms, Bell and Howell Information and Learning Keyword(s): Child Care; Child Health; Health/Health Status/SF-12 Scale; Home Observation for Measurement of Environment (HOME); Household Composition; Morbidity; Peabody Individual Achievement Test (PIAT- Math); Peabody Individual Achievement Test (PIAT- Reading); Peers/Peer influence/Peer relations; Pre-natal Care/Exposure; Pre/post Natal Behavior; Pre/post Natal Health Care The purpose of this project was to examine the independent and interactive effects of early health morbidity and environmental risk factors on the cognitive functioning of children as they entered school. A large national sample of 867 children was drawn from the NLSY of five- and six-year olds who completed the 1986 NLSY assessment battery. Data available included reported maternal substance use during pregnancy, length of gestation, birthweight, length of hospitalization after birth, infant health status, daycare participation, Head Start participation, family income, household composition, level of maternal education, quality of the home environment and current child health. The dependent measure included 3 subtests of the Peabody Individual Achievement Test (PIAT): Mathematics, Reading Recognition, and Reading Comprehension. Analysis techniques included correlation analysis, analysis of variance, and hierarchical multiple linear regression. The results of multivariate modelling was confirmed twice, once on half of the sample that was reserved from multivariate analyses and once on the cohort of children that completed the 1988 NLSY assessment. Results of the analyses indicated that environmental factors had the most significant impact on child outcome. The quality of the home environment mediated most of the effect of the environment although level of maternal education appeared to have some independent effect on reading abilities. There was little impact of health factors on child performance 1986. However, there was a suggestion of some influence of early health morbidity on the change in performance over time. A robust interaction between daycare and income emerged wherein daycare participation appeared to reduce the gap between low income children and their higher income peers. |
