This is according to a study of 25,624 Norwegian women, reported in the New England Journal of Medicine and consequently in Self magazine, September 1997, page 95.

Am I the only one who noticed that if you read the comma in that number (of women studied) as "or", it (the number) is the title of a song by Chicago? Is that just weird?

Sadly, 25,624 is not divisible by 37.
