Âge parental et psychopathologie des descendants dans la cohorte neurodéveloppementale de Philadelphie

Aperçu: G.M.
Les âges parentaux plus jeunes étaient généralement associés à des taux accrus de psychopathologie des descendants. Après avoir contrôlé les caractéristiques socio-démographiques et la comorbidité, les âges maternels et paternels plus jeunes ont été associés à des syndromes de comportement et à une psychose chez les jeunes, alors que l'âge paternel avancé était associé à des troubles du développement / troubles du spectre de l'autisme.
Ces résultats suggèrent que l'âge des parents plus jeune et plus âgé à la naissance est associé à des formes spécifiques de psychopathologie chez les descendants. La persistance de l'influence de l'âge parental après le contrôle des facteurs démographiques et un indice de l'environnement social suggère nt que des explications supplémentaires pour ces résultats devraient être examinées dans les études futures.

Abstract

OBJECTIVE:

Increasing evidence implicates advanced paternal age at offspring birth in neuropsychiatric disorders. Advanced maternal age has also been associated with schizophrenia and other neurodevelopmental disorders, whereas younger maternal age has been linked with behavioral disorders. Few studies have considered the specificity of the associations with respect to comorbidity. In addition, most prior studies have been conducted in clinical samples or registries that may reflect more severe forms of psychopathology. The aim of this research is to examine the independent and joint associations of maternal and paternal age with specific subtypes of psychopathology in offspring in a pediatric sample of adolescents with emergent psychiatric syndromes.

METHOD:

A total of 8,725 youths (aged 8-21 years) from the Philadelphia Neurodevelopmental Cohort were included in the analyses. Logistic regression models with parental age predicting offspring psychopathology were adjusted for sociodemographic factors and comorbid disorders.

RESULTS:

We found that younger parental ages were generally associated with increased rates of offspring psychopathology. After controlling for sociodemographic characteristics and comorbidity, both younger maternal and paternal ages were associated with behavior syndromes and psychosis in youth, whereas advanced paternal age was associated with pervasive developmental disorders/autism spectrum disorder (PDD/ASD).

CONCLUSION:

These findings suggest that both younger and older parental age at birth are associated with specific forms of psychopathology in offspring. The persistence of the influence of parental age after control for demographic factors and an index of social environment suggests that additional explanations for these findings should be examined in future studies.
