any worse in school than those with fathers in their 30s, as researchers
had once feared, according to a new study from Karolinska Institutet pu
blished in the online science journal PLoS ONE.
The average age of a man at the birth of his first child has risen sharp
ly over the past few decades, a trend that is particularly pronounced in
the Stockholm region. Several earlier studies have revealed a correlati
on between the father's age and the risk of his child developing uncommo
n neuropsychiatric diseases, such as schizophrenia and bipolarism. Recen
s cognition.
Researchers at Karolinska Institutet have therefore conducted a study to
see if there is a similar correlation between high paternal age and the
child's final year-nine grades. This present study is based on data fro
m over 135,000 children in Stockholm, who left compulsory school between
2000 and 2007, and tested the hypothesis that any negative consequences
of the father's age on the child's IQ would be offset by the social adv
antages that being raised by older parents brings.
"To the delight of fathers choosing to wait before having children, our
results suggest that children of older fathers perform no worse in schoo
l," says Anna Svensson, study leader at the Department of Public Health
Sciences. "When we studied children's final year-nine grades we could se
e no difference between children of fathers in their 50s and children of
fathers in their 30s."
Children of even younger fathers performed slightly worse in school, alt
hough these difference could largely be attributed to differences in the
parents' own educational background.
