Objective

The aim of this study was to examine paternal age in relation to risk of autism spectrum disorders (ASDs) in a setting other than the industrialized west.

Design

A case-control study of Aruban-born children (1990–2003). Cases (N?=?95) were identified at the Child and Adolescent Psychiatry Clinic, the only such clinic in Aruba; gender and age matched controls (N?=?347) were gathered from public health records. Parental age was defined categorically (=29, 30–39, 40–49, =50y). The analysis was made, using conditional logistic regression.

Results

Advanced paternal age was associated with increased risk of ASDs in offspring. In comparison to the youngest paternal age group (=29y), risk of autism increased 2.18 times for children born from fathers in their thirties, 2.71 times for fathers in their forties, and 3.22 thereafter.

Conclusion

This study, part of the first epidemiologic study of autism in the Caribbean, contributes additional evidence, from a distinctive sociocultural setting, of the risk of ASD associated with increased paternal age.
