Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 8 to 17 years
  • Men only
  • Healthy volunteers accepted
  • Child

Study population: Adolescent boys, ages 8-17 years, recruited from a clinic population (ASD) or community advertisements (ASD and control) matched for age.

Who may be able to join

  • Boys 8-17 years chronological age
  • BMI between the 3rd and 97th percentiles
  • Meets DSM-IV criteria for Autism Spectrum Disorder (ASD group)
  • Scores <15 on the Social Communication Questionnaire (control group)

Who cannot join

  • Use of medications directly affecting bone metabolism including estrogen/ progesterone preparations and glucocorticoids except local application of glucocorticoid
  • Use of anticonvulsants which affect bone density including diphenylhydantoin, phenobarbital, topiramate carbamazepine and valproic acid and also use of lithium
  • Children with diseases known to affect bone mineral density including Crohn's disease, celiac, thyroid and renal
  • Children who will not tolerate lying still for 30 seconds

About this study

This is a observational study to investigate the degree to which bone mineral density is impaired in boys with autism compared with typically developing controls.

Read the detailed description

Studies have shown that bone cortical thickness is decreased in children with autism and other developmental disabilities. However it is not known whether bone mineral density (BMD) of these children is lower; neither is it known whether there is any correlation between BMD and the child's diet. The overall goal of this study is to improve the long term health of children and adolescents with autism spectrum disorder; more specifically the investigators aim to develop a pilot study to investigate the degree to which BMD is impaired in boys with autism and to explore specific additional risk factors. In addition, the aim is to investigate the degree to which BMD is impaired in boys with Autism Spectrum Disorder (ASD) and to explore specific contributing risk factors including nutritional analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bone Mineral Density

    using dual energy x-ray absorptiometry (DXA) (Hologic Discovery A, Software Version: APEX 4.0.2, Bedford, MA USA) at the total hip, femoral neck, lumbar spine (L1-4), whole body and whole body less head bone mineral density.

    Measured: Bone mineral density will be assessed within one month of enrolling in the study.

Questions about this trial

What is this clinical trial studying?

An observational study of Autism Spectrum Disorder and Bone Diseases, Developmental, run by Massachusetts General Hospital.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 May 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bone Mineral Density (time frame: Bone mineral density will be assessed within one month of enrolling in the study.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 May 2017.
