Role of fruits, grains, and seafood consumption in blood cadmium concentrations of Jamaican children with and without Autism Spectrum Disorder / Mohammad H. RAHBAR in Research in Autism Spectrum Disorders, 8-9 (September 2014)

Utilizing data from 110 age- and sex-matched case–control pairs (220 children) ages 2–8 years in Kingston, Jamaica, we compared the 75th percentile of blood cadmium concentrations in children with and without Autism Spectrum Disorder (ASD). In both univariable and multivariable Quantile Regression Models that controlled for potential confounding factors, we did not find any significant differences between ASD cases and typically developing (TD) controls with respect to the 75th percentile of blood cadmium concentrations (P gt; 0.22). However, we found a significantly higher 75th percentile of blood cadmium concentrations in TD Jamaican children who consumed shellfish (lobsters, crabs) (P lt; 0.05), fried plantain (P lt; 0.01), and boiled dumpling (P lt; 0.01). We also observed that children living in Jamaica have an arithmetic mean blood cadmium concentration of 0.16 ?g/L which is similar to that of the children in developed countries and much lower than that of children in developing countries. Although our results do not support an association between blood cadmium concentrations and ASD, to our knowledge, this study is the first to report levels of blood cadmium in TD children as well as those with ASD in Jamaica.

Titre : Role of parental occupation in autism spectrum disorder diagnosis and severity Type de document : Texte imprimé et/ou numérique Auteurs : Aisha S. DICKERSON, Auteur ; Deborah A. PEARSON, Auteur ; Katherine A. LOVELAND, Auteur ; Mohammad H. RAHBAR, Auteur ; Pauline A. FILIPEK, Auteur Article en page(s) : p.997-1007 Langues : Anglais (eng) Mots-clés : Autism Diagnosis Severity Risk Occupation Parents Index. décimale : PER Périodiques Résumé : Abstract Some have suggested that parents of children with autism spectrum disorder (ASD) may present with less recognizable autistic-like phenotypic characteristics, leading them to highly systemizing occupations. Using secondary analysis of data from two previous studies of children with ASD, we tested associations between parental occupations and ASD diagnosis and the association of parental occupational characteristics on ASD severity. We found that fathers in healthcare (P lt; 0.01) and finance (P = 0.03) were more likely to have children with ASD. Additionally, joint effects of parental technical occupations were associated with communication (P lt; 0.01) and social impairment (P = 0.04). These results support that a “broader phenotype” and possible assortative mating in adults with autistic-like characteristics might contribute to intergenerational transmission and having offspring with greater ASD severity.

Titre : Severity of Child Autistic Symptoms and Parenting Stress in Mothers of Children with Autism Spectrum Disorder in Japan and USA: Cross-Cultural Differences Type de document : Texte imprimé et/ou numérique Auteurs : Noriko PORTER, Auteur ; Katherine A. LOVELAND, Auteur ; Sepideh SAROUKHANI, Auteur ; Yana POSEY, Auteur ; Kana MORIMOTO, Auteur ; Mohammad H. RAHBAR, Auteur Article en page(s) : 7089053 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The purpose of this study was to compare the relationship between parenting stress and autistic symptom severity in the U.S. and Japan. Fifty-two U.S. and 51 Japanese mothers of children aged 2-12 with autism completed measures of parenting stress and child characteristics, including the parenting stress index (PSI), the social communication questionnaire (SCQ), and social responsiveness scale-2 (SRS-2). There was a nonlinear relationship between the child's autistic symptom severity and parenting stress in both countries. We also found some cultural differences: in the parent domain, the relationships between children's SCQ scores and PSI scores differed significantly between the U.S. and Japan. Our findings suggest that autistic severity symptom scores may reflect cross-cultural differences in parenting beliefs, views toward autism, and response styles for evaluating children's behavior. The findings also suggest that parents need support regardless of the child's autism severity, including those with mild to moderate symptoms. Expanding on this line of research and understanding cultural influences on parenting stress may help service providers and agencies offer more culturally sensitive services, parent-education courses, and intervention programs.

Our findings, indicate that among children who had the Ile/Ile genotype for GST pi 1 (GSTP1), those with BMC ? 12 ?g/L had about 4 times higher odds of ASD than those with BMC < 12 ?g/L, (P = 0.03) under a co-dominant genetic model. After adjusting for potential confounders, among the subgroup of children with genotype Ile/Ile, those with BMC ? 12 ?g/L had about six times higher odds of ASD than those with BMC < 12 ?g/L, (P = 0.04). The results were similar when a recessive genetic model was used. These findings suggest a possible synergic effect of BMC and GSTP1 in ASD. Since our analysis included a variety of genetic models and was not adjusted for multiple testing, replication in other populations is warranted.

The flexible administration requirements of the Childhood Autism Rating Scale have resulted in its use in both high-income countries and low- and middle-income countries. This study examines the agreement between assessments using the Childhood Autism Rating Scale with those using the Autism Diagnostic Observation Schedule or Autism Diagnostic Observation Schedule, Second Edition and Autism Diagnostic Interview?Revised in Jamaica. Children aged 2?8?years (n=149) diagnosed with autism by an experienced clinician using the Childhood Autism Rating Scale were re-evaluated using the Autism Diagnostic Observation Schedule and Autism Diagnostic Interview?Revised. The proportion diagnosed with autism spectrum disorder using the Autism Diagnostic Observation Schedule, Autism Diagnostic Observation Schedule, Second Edition, and Autism Diagnostic Interview?Revised was determined and mean domain scores compared using analysis of variance (ANOVA). The mean age was 64.4 (standard deviation=21.6)?months; the male:female ratio was 6:1. The diagnostic agreement of the Childhood Autism Rating Scale with the Autism Diagnostic Observation Schedule and Autism Diagnostic Observation Schedule, Second Edition was 100.0% and 98.0%, respectively. Agreement with the Autism Diagnostic Interview?Revised was 94.6%. Domain scores were highest for children with more severe symptoms (p?0.01). Despite a high level of agreement of the Childhood Autism Rating Scale with the Autism Diagnostic Observation Schedule, Autism Diagnostic Observation Schedule, Second Edition, and Autism Diagnostic Interview?Revised, the Childhood Autism Rating Scale should be evaluated further with a broader range of autism spectrum disorder symptomatology, and by clinicians with varying experience before recommendation for use in low- and middle-income countries.
