“…17 Decreased IQ scores, dyslexia, and an increased risk for schizophrenia in children have also been associated with increased paternal age. [18][19][20][21] In the present study we used vital statistics and health data from the North Dakota Health Registry to examine the effects of paternal and maternal age on birth weight and related newborn measures within the context of the two main racial groups in the state, Caucasians, and Native Americans. Our interest in Native Americans was prompted by the rising concern for the health of newborns among Native Americans.…”

The purpose of this study was to compare the effects of maternal and paternal age on Native American and Caucasian infants. Data were abstracted from birth records compiled in North Dakota from 1978 to 1992. Native Americans had a 45% higher risk for preterm births, a 140% higher risk for low birth weight (LBW) (<2500 g), and a 131% higher risk for very LBW (<1500 g) compared with Caucasians. Maternal and paternal age both had a "U-shaped" effect on preterm birth. However, while the risk for preterm birth was increased for both teenage mothers and fathers, the risk was also significantly increased only for mothers between the ages of 36-40 and 41-45. There was also a "U-shaped" relationship between LBW and parental age, and again the risk was statistically significant for different age groups. For mothers, the risk was decreased significantly for those 26 to 30 years of age, whereas for fathers, it was increased significantly for those <20 years of age. There was also a significant interaction between paternal age and race, with teenage Native American fathers having a slight (4%), but statistically significant, increased risk for having LBW children compared with teenage Caucasian fathers. The relationship between parental age and very LBW was also "U-shaped," but while the odds ratios for each maternal age group were significant, none of the odds ratios for any of the paternal age groups was statistically significant. The influence of teenage fathers on preterm and LBWs has not been previously reported, and the finding that paternal age has a greater influence among Native Americans is especially intriguing and deserving of further investigation.

“…In short, the true corpus of research that addresses the latter issue consists of the remaining 10 papers based upon nine datasets (Dartigues et al, 1992;Globerson, 1983;Hitchcock and Oliver, 1976;Hota, 1983;Mercer and Smith, 1972;O'Connor et al, 1989;Roberts, 1971;Roberts and Engel, 1974;Sen and Goel, 1982;Vernon and Mitchell, 1974), together with the articles by Bjorkland and Weiss (1985) and by Newcomb and Collins (1979). Unfortunately, three of these papers did not provide enough information to compute an index of eect size: Hota (1983) reported percentage correct performance in subjects of high SES and low SES but no evidence regarding variability, whereas Newcomb and Collins (1979) and O'Connor et al (1989) reported signi®cant eects of SES in the context of complex multivariate analyses from which it is impossible to derive any measures of variation.…”

Socio-economic status, social class and memory performance: a critical response to Herrmann and Guadagno (1997)

Herrmann and Guadagno (1997) reviewed evidence concerning the relationship between memory performance and socio‐economic status (SES). As a measure of social stratification, SES is narrow and ethnocentric, and it ignores the role of social prestige, power and status. The selection of research for quantitative analysis and the measure of effect size used by Herrmann and Guadagno are criticized. Across the available corpus of studies, there is a highly significant relationship between SES and memory performance, but this varies systematically from one task to another and between different research studies using the same task. This indicates that the effects of SES on memory are mediated by the content and the context of learning. Copyright © 1998 John Wiley & Sons, Ltd.

“…Earlier studies noted an association between APA and poorer performance on neurocognitive tests [31–34]. This issue has been addressed specifically in a recent study based on male and female Israeli conscripts (age 16–17 y, n = 44,175) [35].…”

Advanced Paternal Age Is Associated with Impaired Neurocognitive Outcomes during Infancy and Childhood

et al. 2009

BackgroundAdvanced paternal age (APA) is associated with an increased risk of neurodevelopmental disorders such as autism and schizophrenia, as well as with dyslexia and reduced intelligence. The aim of this study was to examine the relationship between paternal age and performance on neurocognitive measures during infancy and childhood.Methods and FindingsA sample of singleton children (n = 33,437) was drawn from the US Collaborative Perinatal Project. The outcome measures were assessed at 8 mo, 4 y, and 7 y (Bayley scales, Stanford Binet Intelligence Scale, Graham-Ernhart Block Sort Test, Wechsler Intelligence Scale for Children, Wide Range Achievement Test). The main analyses examined the relationship between neurocognitive measures and paternal or maternal age when adjusted for potential confounding factors. Advanced paternal age showed significant associations with poorer scores on all of the neurocognitive measures apart from the Bayley Motor score. The findings were broadly consistent in direction and effect size at all three ages. In contrast, advanced maternal age was generally associated with better scores on these same measures.ConclusionsThe offspring of older fathers show subtle impairments on tests of neurocognitive ability during infancy and childhood. In light of secular trends related to delayed fatherhood, the clinical implications and the mechanisms underlying these findings warrant closer scrutiny.
