Tackling Autism and the Autistic Spectrum
, 04 04th, 2008
Autism education a never-ending challenge.
Growth and Maturation in Children with Autism or Autistic Spectrum Disorder (ASD)
Principal investigator: Mary L. Hediger, Ph.D.
Children with autism and autistic spectrum disorder (ASD) suffer from defects in socialization, verbal and nonverbal communication, and response to sensory stimuli. While the cause of autism is unknown, children with autism and ASD have been noted in several studies to have a high prevalence of macrocephaly and appear to be taller on average than the general population. Growth patterns and markers of maturation in autistic children have not been studied in detail. Dehydroepiandrosterone sulfate (DHEA-S), a marker for adrenal maturation, is low in early childhood but increases during the mid-growth spurt (about ages six to eight). DHEA-S concentration appeared to be elevated in autistic children compared with normal controls in one previous study, raising questions about the possibility that early elevations of DHEA-S in autistic children may be associated with large head and body size. Other methods of assessing maturation in autistic children, such as bone age and cortical thickness, have not been explored.
This study uses cross-sectional data to assess growth and maturation of children with autism/ASD in three ways:
Height, weight, body mass index (BMI) and head circumference in children with autism/ASD between four and eight years of age will be compared with developmentally normal age-, gender-, and race-matched controls
DHEA-S levels in children with autism/ASD will be compared with the same developmentally normal controls
Bone age in children with autism/ASD will be compared with reference populations. Recruitment of 80 case children and 80 controls has been completed.
Case children were recruited from a clinic where a large number of autistic children are seen. Control children were recruited at outpatient surgery facilities.
