Children of Older Fathers Have Lower IQs
Children of older fathers have lower IQs

The children of older fathers scored lower than the offspring of younger fathers on IQ tests and a range of other cognitive measures at 8 months old, 4 years old, and 7 years old, according to a study released yesterday that added to a growing body of evidence suggesting risks to postponing fatherhood.

The study is the first to show that the children of older fathers do not perform as well on cognitive tests at young ages. Although the differences in scores were slight and usually off by just a few points on average, the study's authors called the findings "unexpectedly startling."
"The older the dads were, the slightly worse the children were doing," said Dr. John J. McGrath, the paper's senior author and a professor of psychiatry at the Queensland Brain Institute in Brisbane, Australia. "The findings fit in a straight line, suggesting there may be some steady beat of mutations happening in the dad's sperm."
Earlier studies have found a higher incidence of schizophrenia and autism among the offspring of men who were in their mid-to-late 40s or older when they had children. A study published in 2005 reported that 16-year-olds and 17-year-olds with older fathers scored lower on nonverbal IQ tests, as did the offspring of teenage fathers.
The new study, published Monday in the online journal PLoS Medicine, reanalyzed data from the federally sponsored Collaborative Perinatal Project, which gathered information from more than 50,000 pregnant women seen at 12 university clinics in the United States from 1959 to 1965.
The researchers analyzed the scores of 33,437 children who, as part of the project, had been tested at regular intervals in a variety of cognitive skills, including thinking and reasoning, concentration, memory, understanding, speaking and reading, as well as motor skills. Fathers in the study were age 14 to 66, while mothers were 12 to 48.
Regardless of their mothers' ages, children whose fathers were 50 years old had lower scores on all tests, except those assessing physical coordination, than those whose fathers were 20, the researchers found. And the older the fathers, the more likely the children were to have lower scores, they found.
By contrast, children with older mothers generally performed higher on the cognitive measures, a finding in line with most other studies, suggesting that these children may benefit from the more nurturing home environments associated with the generally higher income and education levels of older mothers, researchers said.
"I think there has been a bit of a cultural bias against even looking at this issue, but finally people are willing to entertain this," said Dr. Dolores Malaspina, a professor of psychiatry at New York University Medical Center who has written studies on the risk of schizophrenia among children of older fathers as well as the lower nonverbal IQ scores found among teenagers with older fathers.

Re: Children of Older Fathers Have Lower IQs
There is a bigger problem when the mother is older than 30 because the kids are more likely to become physically and mentally handicapped.........not just lower IQs.siren wrote:Gifted wrote:Now I know why![]()

Re: Children of Older Fathers Have Lower IQs
all these "studies" are full of shit!. they want teenagers and young men to have kids early, so they could struggle to take care of their kids instead of looking hard at their surroundings and becoming politicaly and socially active!.
