| Abstract |
In a total population survey of childhood psychosis in the region of Göteborg, 20 children (2 in every 10,000) fulfilled the diagnostic criteria for infantile autism formulated by Rutter. There was a male preponderance with 15 boys and 5 girls. Eighty-five percent of the mothers were older than average. Mean maternal age in the autistic sample was 30.7 years, compared with 26.0 years in the general population. The difference is statistically significant at the .1% level. There was a strong tendency toward increasing risk of autism in the child with increasing maternal age. The fathers too were much older than average. |

Attention Score in Context
This research output has an Altmetric Attention Score of 22. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 June 2018.
All research outputs
#1,589,071
of 23,867,274 outputs
Outputs from Journal of Autism and Developmental Disorders
#666
of 5,240 outputs
Outputs of similar age
#105
of 6,697 outputs
Outputs of similar age from Journal of Autism and Developmental Disorders
#1
of 2 outputs
Altmetric has tracked 23,867,274 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,240 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 13.2. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 6,697 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 98% of its contemporaries.
We're also able to compare this research output to 2 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
