Maternal Exposures Associated with Autism Spectrum Disorder in Jamaican Children.

The study relied on self-reported data collected retrospectively, which introduces the risk of recall bias where parents of children with ASD may remember exposures differently than parents of typically developing children. The analysis was secondary to the main study aims, meaning the questionnaire did not capture detailed timing or specific types of fever, infection, or trauma, and data on antipyretic medication use was missing. There was a potential selection bias because controls were recruited primarily from urban Kingston schools and clinics, while cases were distributed across various parishes, which may affect exposure patterns. The study did not correct for multiple comparisons, increasing the chance that some significant findings occurred by chance. Small sample sizes for certain exposure groups led to wide confidence intervals and a lack of statistical power to detect some associations.

The text does not explicitly state funding sources or author conflicts of interest, but it notes collaboration between the University of the West Indies and the University of Texas Health Science Center at Houston.

Do not interpret these associations as proof that these specific exposures cause autism. The study design is retrospective and relies on memory, which is prone to bias, and it cannot establish causality or rule out other confounding factors.
