Sociodemographic risk factors associated with autism spectrum disorders and intellectual disability / Judith PINBOROUGH-ZIMMERMAN in Autism Research, 4-6 (December 2011)
[article]
Titre : Sociodemographic risk factors associated with autism spectrum disorders and intellectual disability Type de document : Texte imprimé et/ou numérique Auteurs : Judith PINBOROUGH-ZIMMERMAN, Auteur ; Deborah A. BILDER, Auteur ; Amanda V. BAKIAN, Auteur ; Robert SATTERFIELD, Auteur ; Paul S. CARBONE, Auteur ; Barry E. NANGLE, Auteur ; Harper RANDALL, Auteur ; William M. MCMAHON, Auteur Année de publication : 2012 Article en page(s) : p.438-448 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examined the hypotheses that (1) sociodemographic risk factors in young children with autism spectrum disorders (ASD) and/or intellectual disability (ID) significantly vary by disability type, and (2) measures of income (mean adjusted gross income, mean federal taxes paid, and mean tax exemptions) significantly increase between 1994 and 2002, and are lower in families with a child with ASD and/or ID compared with the general population. A multiple source surveillance system utilizing a retrospective record review was used to identify ASD and ID cases from a population of 26,108 eight-year-old children born in 1994 and living in Utah in 2002. ASD without ID (ASD-only, n = 99) cases were significantly more likely to be male (P<0.01) and have mothers of White non-Hispanic ethnicity (P = 0.02). ASD with ID (ASD/ID, n = 33) cases were significantly more likely to be male (P<0.01) and have mothers older than 34 years (P = 0.03). ID without ASD (ID-only, n = 113) cases were significantly more likely to have fathers older than 34 years (P<0.01) and were significantly less likely to have mothers with >13 years education (P<0.01). Measures of income for cases at birth and at 8 years of age were not significantly lower than the general population and mean adjusted income of cases significantly increased from birth to 8 years of age. Investigations focused on defining early sociodemographic risk factors by different endophenotypes of ASD may assist in identifying risk factors for this complex group of neurodevelopmental disorders. Aggregate tax information may be a unique resource to utilize for population-based analysis.

Titre : Spatial Relative Risk Patterns of Autism Spectrum Disorders in Utah Type de document : Texte imprimé et/ou numérique Auteurs : Amanda V. BAKIAN, Auteur ; Deborah A. BILDER, Auteur ; Hilary COON, Auteur ; William M. MCMAHON, Auteur Article en page(s) : p.988-1000 Langues : Anglais (eng) Mots-clés : Ascertainment age Autism spectrum disorders Diagnostic age Maternal residential birth address Socioeconomic status Spatial analysis Race/ethnicity Index. décimale : PER Périodiques Résumé : Heightened areas of spatial relative risk for autism spectrum disorders (ASD), or ASD hotspots, in Utah were identified using adaptive kernel density functions. Children ages four, six, and eight with ASD from multiple birth cohorts were identified by the Utah Registry of Autism and Developmental Disabilities. Each ASD case was gender-matched to 20 birth cohort controls. Demographic and socioeconomic characteristics of children born inside versus outside ASD hotspots were compared. ASD hotspots were found in the surveillance area for all but one birth cohort and age group sample; maximum relative risk in these hotspots ranged from 1.8 to 3.0. Associations were found between higher socioeconomic status and birth residence in an ASD hotspot in five out of six birth cohort and age group samples.

Titre : The relationship between executive functioning, central coherence, and repetitive behaviors in the high-functioning autism spectrum Type de document : Texte imprimé et/ou numérique Auteurs : Mikle SOUTH, Auteur ; Sally OZONOFF, Auteur ; William M. MCMAHON, Auteur Année de publication : 2007 Article en page(s) : p.437-451 Langues : Anglais (eng) Mots-clés : Autism Central-coherence Executive-function Repetitive-behavior Index. décimale : PER Périodiques Résumé : This study examined the relationship between everyday repetitive behavior (primary symptoms of autism) and performance on neuropsychological tests of executive function and central coherence (secondary symptoms). It was hypothesized that the frequency and intensity of repetitive behavior would be positively correlated with laboratory measures of cognitive rigidity and weak central coherence. Participants included 19 individuals (ages 10—19) with high-functioning autism spectrum disorders (ASD group) and 18 age- and IQ-matched typically developing controls (TD group). There was partial support in the ASD group for the link between repetitive behavior and executive performance (the Wisconsin Card Sorting Task). There was no support for a link between repetitive behavior and measures of central coherence (a Gestalt Closure test and the Embedded Figures Test). Further research on repetitive behaviors in autism may benefit from a focus on narrow behavioral and cognitive constructs rather than general categories.

The FIPS-A is based on register linkages between births from 1987 to 2005 ascertained from the Finnish Medical Birth Register (FMBR) and other national registers on treatment for this group of disorders. All subjects were members of the Finnish Maternity Cohort (FMC), which consists of virtually all births in Finland from 1983 to the present, and which includes archived maternal serum samples. This study also capitalizes on other registry information, such as systematically collected data on pregnancy, prenatal and neonatal complications and manual data collection from well-child clinics providing developmental data from birth to the age of 7 years. In this paper, we describe the methods used in the FIPS-A study, including a description of the national registers, available data and case ascertainment procedures. Finally, we discuss implications of the data for future work on uncovering putative aetiologies of ASD and key strengths and limitations of the design.

JENSON, Auteur ; Michael GARDNER, Auteur ; Heidi BLOCK, Auteur ; Carmen B. PINGREE, Auteur Année de publication : 2009 Article en page(s) : p.109-118 Langues : Anglais (eng) Mots-clés : autism adult outcome longitudinal Index. décimale : PER Périodiques Résumé : Previous studies found substantial variability in adult outcome for people with autism whose cognitive functioning was within the near-average and average ranges. This study examined adult outcome for 41 such individuals (38 men and 3 women) originally identified through an epidemiological survey of autism in Utah. Mean age at the time of their previous cognitive assessment was 7.2 years (SD=4.1, range=3.1-25.9 years) and at follow-up was 32.5 years (SD=5.7 years, range=22.3-46.4 years). Outcome measures included standardized assessments of diagnostic status, cognitive ability, and adaptive behavior. Additional information collected concerned demographic variables, indicators of independence, social relationships, medical and psychiatric conditions, and social service use. Outcomes for this sample were better than outcomes described in previous work on individuals with similar cognitive functioning. For example, half of the participants were rated as Very Good or Good on a global outcome measure. As in previous studies, there was considerable variability in measured cognitive ability over time. Over half of the sample had large gains or losses of cognitive ability of greater than 1 standard deviation. Cognitive gain was associated with better outcome, as was better adaptive functioning. While all participants had baseline IQs in the nonimpaired range, there was limited evidence to support the use of other early childhood variables to predict adult outcome.
