BACKGROUND: Emerging evidence suggests endocrine disrupting chemicals, including bisphenols and phthalates, may affect behavioral development in children and adolescents. Risk behavior constitutes a potentially sex hormone sensitive behavioral construct. Here, we examined longitudinal associations of phthalate and bisphenol exposure with performance-based tasks and self-reported risk-taking behaviors.
METHODS: Within a population-based birth cohort in the Netherlands, urinary bisphenols and phthalate metabolite concentrations were measured in women during pregnancy (three times, n = 1379) and in children (once at 6 years, n = 775). At 10 years, child risk-taking behavior was assessed with the computerized experimental Columbia Card Task (CCT). At 14 years, adolescents completed a computerized self-assessment of real-life risk-taking behaviors. Linear regression and hurdle models adjusted for confounders were applied in the whole sample and stratified by sex at birth.
RESULTS: After multiple testing correction, no associations in all children or in boys were found for prenatal or childhood phthalate exposure with the average CCT-score. In girls, prenatal mono-isobutyl phthalate was associated with a higher average CCT-score, indicting more risk-taking (B per 10-fold increase in creatinine-adjusted average prenatal levels = 2.10, 95% CI: 0.69,3.52). No associations were observed for bisphenol exposure nor for self-reported risk-taking.
CONCLUSIONS: Prenatal phthalate exposure was associated with more risk-taking in an experimental task at 10 years-of-age in girls only. The task reflects risky decision-making, which may be a hormonally sensitive construct. Risky decision making potentially precedes real-life risk-taking, which was captured by the self-reported measure and was limited in this young sample.
