Does increasing paternal age put a child at any greater risk of antisocial juvenile behavior? I don't know?

OBJECTIVES: To establish the contributions of birth weight (BW), gender, socioeconomic status (SES), and parental age on risks for special education (SE) placements in school-age children. METHODS: A population-based sample of 900 school-age children attending the following full-time SE groups: at level 1, children had isolated neurodevelopmental, physical, or other impairments; at level 2, borderline to mild intellectual disability (ID); and at level 3, moderate to severe ID. Three hundred and one children enrolled in mainstream education formed the control group (level 0). For all children with siblings, we defined familiar forms of learning disorders as having a sibling in one of the SE groupings. We performed our analysis for the entire cohort as well as comparing risk factors within the familial and non-familial types of SE groupings. RESULTS: In multinomial logistic regression analysis, age of father 40 years, low BW (<2500g or <-2 SD), male sex, and parent's lower SES, all increased the probability of SE placement. In the familial forms of levels 2 and 3, the parental SES was lower and, in addition, in the level 2, the family size was bigger. Furthermore, in the non-familial form of level 2, both the low and the high (4000g) BW were more common. CONCLUSIONS: Among the known risk factors for learning disabilities (LD), our study highlighted the importance of a higher paternal age and a lower SES especially in the familial forms of LD.

Abstract This article reviews evidence regarding contributions of neuropsychiatric and psychological vulnerabilities to violent delinquency, and the interaction between intrinsic vulnerabilities and experiential factors in the genesis of antisocial juvenile behavior. Consideration is given to biochemical and physiological factors, genetics, medical status, and neurological, psychiatric, and neuropsychological factors. Implications for treatment are discussed.

A retrospective study of the prevalence of child neuropsychiatric disorders was done involving pervasive developmental disorder (PDD), attention-deficit/hyperactivity disorder (ADHD), and Tourette syndrome in young offenders (15-22 years, n = 126) consecutively referred for presentencing forensic psychiatric investigation (FPI) in Stockholm, Sweden. Most offenders were referred for FPI because of serious offenses. Case report sheets were prepared, and retrospective neuropsychiatric DSM IV diagnoses were made by the first two authors. For best-estimated diagnoses, the case report sheets were then submitted to the fifth author, a child neuropsychiatrist with expertise in this area. Fifteen percent of the subjects had a definite diagnosis of ADHD, and another 15 percent had PDD, including 12 percent PDD not otherwise specified (NOS) and 3 percent Asperger syndrome. Autistic disorder was not found in any case. Tourette syndrome occurred in two percent of the cases. The rate of PDD is particularly striking. Neuropsychiatric diagnoses had been determined in the FPI in only a few cases. The contribution of constitutional problems to later criminal development may have been underestimated.
