Description
A dataset from a case-control study compares urinary heavy metal concentrations and environmental exposures between children with autism spectrum disorder (ASD) and neurotypical controls. The study, conducted by Nevine Khairy Elkady between September and December 2024, involved 25 ASD patients and 25 matched controls aged 5–14 years from Cairo University's Kasr Al Ainy Hospital. It includes standardized urinary levels of lead, mercury, arsenic, and copper, alongside questionnaire data on sociodemographics and environmental exposures.
Use Cases
Associating prenatal and postnatal complications with ASD status based on questionnaire data.
Comparing urinary arsenic and mercury concentrations between ASD and control groups.
Evaluating environmental risk factors like secondhand smoke exposure as predictors of ASD.
Analyzing the relationship between aluminum cookware usage and ASD prevalence.
Strengths
Includes 50 total participants (25 ASD cases and 25 matched controls).
Reports specific statistical findings, such as significantly higher urinary arsenic (p=0.011) and mercury (p=0.021) in the ASD group.
Collects data on multiple environmental factors, including prenatal pesticide exposure and secondhand smoke.
Limitations
Row count is unknown, which may limit suitability assessment.
