The study's authors said it was the largest of its kind ever conducted and the first to include significant numbers of people in both consanguineous and non-consanguineous groups.
The study included 43 different ethnicities but the largest ethnic groups were Pakistani (45%) and white British (just under 40%).
Of 5,127 babies of Pakistani origin, 37% had married parents who were first cousins, compared to less than 1% of married couples nationally.
It is estimated that, worldwide, more than a billion people live in communities where marriage between blood relatives is commonplace.
Last year, the BiB project found cousins getting married was becoming more common, external among British-born Pakistanis in Bradford than a generation ago.
Aisha Ali Khan, from the city, is healthy but four of her siblings were born disabled as the result of a particular gene carried by both her parents, who are cousins.
