The Relationship between maternal education and mental retardation in 10-year-old children

We conducted a case-control study of mental retardation (MR) in which case children (aged 10 years) were identified from existing records at multiple sources, primarily the public school systems. Control children were drawn from a roster of public school students not receiving special education services. We found that maternal educational level at the time of delivery was strongly and inversely related to a form of MR not accompanied by other serious neurologic conditions. For this isolated form of MR, maternal educational level was by far the most important predictor from among seven sociodemographic variables examined. There was a significant race-education interaction that indicated a steeper gradient in risk among white mothers than among black mothers. Relative to children of white mothers with 12 years of education, all children of black mothers, except those whose mothers had 16 or more years of education, were at increased risk. The results may be useful as a guide for selecting high-risk groups as candidates for early childhood intervention programs.     

Current usage of nonionic contrast

All physicians who had billed Pennsylvania Blue Shield for at least three intravenous contrast studies during 1989 were surveyed on their use of nonionic versus ionic contrast. This surveyed group represents a diversity of hospital sizes, practice types, and group sizes. Of the 383 physician groups surveyed, responses were obtained from 285. The majority of the responding groups were radiologists (94.0%). Nonionic contrast is utilized in 41.3% of all intravenous studies. Radiologists use nonionic contrast in a much greater proportion than nonradiologists (P < 0.0001), with 17.6% of radiologists utilizing nonionic contrast in all of their patients. Conversely, 75% of nonradiologists utilize ionic contrast in all of their patients. For all physician groups surveyed, 40.3% utilize nonionic for at least 50%, while 27.6% use nonionics for more than 75% of their patients. The routine use of steroid premedication prior to the injection of ionic contrast is not a common practice. The increased utilization of nonionic contrast found in this survey may reflect the cross-section of physicians and practice types surveyed or may represent changing practice patterns among physicians utilizing contrast material.     

A second look at second-order belief attribution in autism

Compared the performance of autistic and mentally retarded subjects, all of whom had passed a standard first-order test of false belief, on a new second-order belief task 12 autistic and 12 mentally retarded subjects, matched on verbal mental age (assessed by PPVT and a sentence comprehension subtest of the CELF) and full-scale IQ were given two trials of a second-order reasoning task which was significantly shorter and less complex than the standard task used in all previous research. The majority of subjects in both groups passed the new task, and were able to give appropriate justifications to their responses. No group differences were found in performance on the control or test questions. Findings are interpreted as evidence for the role of information processing factors rather than conceptual factors in performance on higher order theory of mind tasks.This study was supported by a grant from the National Institute of Deafness and Other Communication Disorders (1RO1 DC 01234). We thank Jason Barker for his extensive help with this study. We are also very grateful to the schools where the study was conducted including the League School, and the public school systems in the following towns in Massachusetts: Hanover, Hanson, Hingham, Milton, Plymouth, and Rockland. We offer special thanks to Alan Dewey, Mary Dollar, Sandy D'Giacomo, Herman Fishbein, William Griffin, Nancy Kearns, Judy Monahan, Debbie Newhall, Cay Riley, Robert Sherman, and Kathy Staska for their continued support of our research.     

Psychiatric disorders in adopted children: a profile from the Ontario Child Health Study.

Studies of clinical populations suggest that adopted children are overrepresented among children using mental health facilities, whereas studies using non clinical populations of adopted children have reached mixed conclusions about whether or not there is an increased psychological risk associated with adoption. Data from the Ontario Child Health Study, a community survey of children aged four to 16 years, which included a subpopulation of adopted children, were used to: 1. profile the characteristics of adoptive families; 2. examine the strength of adoptive status as a marker for psychiatric and educational morbidity; and 3. determine the extent to which adoptive status has an independent relationship with psychiatric and educational morbidities. The findings were: 1. adoptive mothers were significantly older than non adoptive mothers, but otherwise adoptive families did not differ significantly from non adoptive families, 2. adoption in boys, but not in girls, was a significant marker for psychiatric disorder and poor school performance; adoption in adolescent girls was a significant marker for substance use; and 3. multivariate analyses demonstrated no independent effect of adoption on psychiatric disorder or poor school performance; for adolescents, adoptive status did have an independent relationship with substance use for girls. The implications of these findings will be discussed.     

Housing for people with aids

People with AIDS are homeless for a variety of reasons, including financial devastation, rejection based on fear of contagion or fear of the dying process, and homeless-ness prior to a diagnosis of AIDS. The author developed and directed the Shanti AIDS Residence Program in San Francisco, the first program to provide housing for people with AIDS. This model is appropriate for single, independent people able to live cooperatively with others. It provides shared living situations for three to six people per apartment, and office staff physically maintain the houses and assure that the needs for community-based home care and other services are met. Other models are proposed for people who are physically or cognitively dependent (and require physical care or supervision in addition to housing), who are socially unable to live cooperatively with others in an unstrucured living environment (e.g., active substance users or the emotionally disturbed), or who have families (e.g., mothers with dependent children or gay men who live with their lovers).     

Ontario Child Health Study follow-up: evaluation of sample loss

This article presents an analysis of sample loss in a 4-year follow-up of children aged 4 to 12 who participated in the Ontario Child Health Study in 1983. Of the 1,617 children participating in the original Ontario Child Health Study, 1,172 (72.5%) were located and enlisted at follow-up in 1987. Based on wave-one assessments, nonparticipants at follow-up tended to have higher levels of psychopathology and family risk variables. Respondents were matched with nonparticipants and differentially weighted to compensate for selective loss. In comparing estimates based on actual (observed) and weighted responses in the follow-up sample, it was found that the effects of sample loss depended on the analytical focus. Evaluations of outcome of disorder and risk for disorder were not affected by sample loss. Evaluation of variables that predict persistence of disorder (prognosis) was affected by a bias toward the null.     

Quality of life and Kaposi sarcoma: using preference techniques to value the health gains from treatment

The goal of this work was to investigate preference techniques to value potential health gains from treatments of Kaposi sarcoma (KS). The study was designed to take the form of face-to-face interviews with a sample of men with a history of HIV/AIDS ( n=15) or HIV/AIDS and KS ( n=17). The main outcome measure was quality of life (QoL) associated with various KS disease states expressed on a scale from 0 (death) to 1 (perfect health), obtained though time trade-off (TTO) and rating scale techniques. For cutaneous lesions only, the mean TTO preference score value was 0.27. In other words, the men were willing to trade a life expectancy of 5 years for a shorter period (1.4 years) in perfect health. More severe KS health states were rated lower (0.07-0.09). The mean rating scale value for cutaneous lesions only was 0.11 and ranged from -0.10 to -0.04 for the more severe conditions; these values were systematically lower than the TTO ( P=0.014). A large overall potential gain in QoL from treatment (partial response minus stable disease) was found for each condition to be reflected in both the TTO (from 0.31 to 0.55) and the rating scale (from 0.38 to 0.44). Respondents associate KS health states with extremely poor QoL and indicate that large gains are possible through modest treatment effects. While TTO returns higher values than the rating scale, potential gains from treatments were similar. The techniques appear to be suitable for application to QoL and economic evaluation of treatments of KS.
