Associations of maternal age at birth and subsequent intelligence test scores of children were examined in a series of over 1500 young men from the Netherlands. All subjects were members of 2-child families and were resident in Amsterdam at age 19 yr. Possible confounding by birth order, spacing interval, social class and sex of sibling were considered. Significant correlations between maternal age and child's ability remained in three of the four possible birth order/social class combinations.

The relationship between age of mother and child health and development.
It is suggested that when relevant background characteristics are controlled, children of teenage mothers are as healthy and develop as well as children of older mothers.
Biosocial correlates of cognitive abilities.
The children in the cohort followed by the National Child Development Study were tested for cognitive ability at the age of eleven, and the influence of a number of biological and social variables

The presence of consistent tendencies for increasing maternal age to be associated with declining risks of educational underachievement, juvenile crime, substance misuse, and mental health problems was indicated.
Older maternal age and child behavioral and cognitive outcomes: a review of the literature.
The trend toward delayed childbearing is widespread in industrialized nations and existing research suggests that children of older mothers are often at lower risk for problem behavioral and academic outcomes compared with offspring of mothers in their teens and twenties.
Is later better or worse? Association of advanced parental age with offspring cognitive ability among half a million young Swedish men.
Although the results confirmed that maternal age was negatively associated with offspring IQ, the association was small enough that delaying parenthood resulted in higher offspring IQ scores because of the positive IQ test score trend.
Progeny's mental aptitudes in man: relationship with parental age at conception and with some environmental factors.
Regarding the respective influences of the environment and of the subject's genome on his cerebral development, one can hypothesize a complementarity between these two factors through the possibility of a genetically determined individual synaptic potential, revealing itself, more or less, according to environmental conditions.
Advanced Paternal Age Is Associated with Impaired Neurocognitive Outcomes during Infancy and Childhood
The offspring of older fathers show subtle impairments on tests of neurocognitive ability during infancy and childhood, and these findings warrant closer scrutiny in light of secular trends related to delayed fatherhood.
Verbal Comprehension in Four‐Year‐Olds as a Function of Maternal Age
Several research studies have shown that children of older mothers perform better on tests of cognitive ability than do children of younger mothers. These differences are not attributed to age per se
Health and social characteristics and children's cognitive functioning: results from a national cohort.
The findings illustrate disparities in cognitive functioning across sociodemographic and health characteristics of children in the US population and suggest the need for public health policies to take a multifaceted approach to optimizing childhood environments in order to overcome the effects of socioeconomic and minority status.
Differences in maternal and paternal age between Schizophrenia and other psychiatric disorders
Maternal and paternal ages were higher for subjects diagnosed with mental retardation and risk for psychotic disorders showed a significant linear increase only with advancing maternal age, and not paternal age as is more often reported.


Child spacing and birth order: effect on intellectual ability in two-child families.
The effect on intellectual ability of the spacing of the birth of siblings was studied and birth-order effect and level of ability were not influenced by length of interval between firstborn and secondborn.
Maternal age and intellectual functioning of offspring.
The null hypothesis that maternal age at the time of delivery has no relationship to the later intellectual functioning of the mothers offspring was tested and found to be incorrect and both intellectual functioning and birth weight increased with maternal age.
The relation of measured intelligence to birth order and maternal age *
The association of measured intelligence with maternal age and birth order in a general population of children is determined mainly by differences between rather than within families, and the negative correlation between sibship size and intelligence cannot be attributed substantially to variation in intelligence.
Birth order, family size, and intelligence.
Birth Order, Family Size, and Intelligence
The relation of birth order and family size to intellectual performance, as measured by the Raven Progressive Matrices, was examined among nearly all of 400,000 19-year-old males born in the
Family Growth and its Effect on the Relationship Between Obstetric Factors and Child Functioning
We know that women from different socio-economic groups also differ in their family building behaviour—in their age at first pregnancy and in the size and spacing of their families. We also know that

This book has been long awaited and finishes up the longitudinal study of 1,000 families in Newcastle upon Tyne, England. It is an account of the children in these families from ages 5 through 15
In this investigation, some relationships between the intelligence test scores obtained by Aberdeen married primigravidae booked for hospital delivery, and their social class, age, height, and general physique and health are studied.
