Thank you! Through your link, I gathered a few keywords and found this: http://www.bmj.com/cgi/content/full/322/7280/199 http://www.bmj.com/cgi/content/full/322/7280/199 Birth weight was also associated with education, with those of higher birth weight more likely to have achieved higher qualifications, and this effect was accounted for partly by cognitive function at age 8.
