Janet,
Here is a portion of an article on CFRD. If you click on the link it takes you to the article and at the bottom there is a link to other recommended reading on CFRD.
"The North American Cystic Fibrosis Foundation, which maintains a registry of approximately 21,000 patients, reported a diabetes prevalence of about 6% in 1998. Because most US CF centers were not screening for diabetes at the time these data were collected and CFRD is often clinically silent, this figure underestimates the true prevalence of diabetes in CF. In Denmark, OGTT screening of the entire CF population demonstrated no diabetes in patients less than 10 years of age, 12% diabetes in individuals age 10-19, and 48% diabetes in adults age 20 and older.
At the University of Minnesota, where annual oral glucose tolerance testing of CF patients is routine, only about half of children and one quarter of adults with CF have normal glucose tolerance (figure 2).
Diabetes is seen in 9% of CF children, 26% of adolescents, 35% of adults age 20-29, and 43% of adults age 30 and older. Of those with diabetes, approximately 1/3 have fasting hyperglycemia (high blood glucose levels when they wake up in the morning before they have eaten) and two-thirds have diabetes without fasting hyperglycemia. Everyone agrees that diabetes with fasting hyperglycemia is dangerous in CF and must be aggressively treated, but there is a lot of disagreement about whether diabetes without fasting hyperglycemia is dangerous. That is because there is so little scientific information about this form of CFRD."

I tried to find when the article was written, but didn't see a date.
Hope that helps,
