We used cases from the Texas birth defect registry, born during 1996\u20132002, to evaluate the association of paternal age with the prevalence of selected structural birth defects. <jats:bold>METHODS:<\/jats:bold> Poisson regression was used to calculate prevalence ratios (PRs) and 95% confidence intervals (CIs) associated with paternal age for each birth defect, adjusting for maternal age, race\/ethnicity, and parity. <jats:bold>RESULTS:<\/jats:bold> Relative to fathers ages 25\u201329 years, fathers 20\u201324 years of age were more likely to have offspring with gastroschisis (PR 1.47, 95% CI: 1.12\u20131.94), and fathers 40+ years old were less likely to have offspring with trisomy 13 (PR 0.40, 95% CI: 0.16\u20130.96). No association was seen between paternal age and prevalence of anencephaly and encephalocele. A selection bias was observed for the other birth defects in which cases of younger fathers were more often excluded from study. <jats:bold>CONCLUSIONS:<\/jats:bold> In studies of birth defect risk and paternal age, the source of information may affect the validity of findings.
