| Résumé : | [BDSP. Notice produite par INIST-CNRS s8koR0xB. Diffusion soumise à autorisation]. Overexposure to glucocorticoids may link prenatal adversity with detrimental outcomes in later life. Glycyrrhiza, a natural constituent of licorice, inhibits placental 11-beta-hydroxysteroid dehydrogenase type 2, the feto-placental "barrier" to higher maternal levels of cortisol. The authors studied whether prenatal exposure to glycyrrhiza in licorice exerts detrimental effects on cognitive performance (subtests of the Wechsler Intelligence Scale for Children III as well as the Children's Developmental Neuropsychological Assessment and the Beery Developmental Test of Visual-Motor Integration) and psychiatric symptoms (Child Behavior Checklist) in 321 Finnish children 8.1 years of age born in 1998 as healthy singletons at 35-42 weeks of gestation. In comparison to the group with zero-low glycyrrhiza exposure (0-249 mg/week), those with high exposure (>500 mg/week) had significant decrements in verbal and visuospatial abilities and in narrative memory (range of mean differences in standard deviation units, - 0.31 to - 0.41 ; P<0.05) and significant increases in externalizing symptoms and in attention, rule-breaking, and aggression problems (range of odds ratios, 2.15 to 3.43 ; P<0.05). The effects on cognitive performance appeared dose related. Data are compatible with adverse fetal "programming" by overexposure to glucocorticoids and caution against excessive intake of licorice-containing foodstuffs during pregnancy. |
