Doctors know what to recommend for people whose scores indicate high or low risk. But it's less clear what to do with those in the middle.

Over the years, researchers have experimented with adding additional risk factors to the formula to try to narrow the grey zone of mid-range results. Now, after testing three dozen separate risk factors, Harvard researchers have found that adding just two --a measurement of C-reactive protein and whether a parent had a heart attack before age 60 -- to the Framingham model made the resulting predictions even more accurate, reports the May 2007 issue of the Harvard Heart Letter.

Based on information collected from more than 24,000 women for more than a decade, the researchers created a new tool called the Reynolds risk score. When used on the study group, the Reynolds risk score did as well as the Framingham risk score for women at high and low risk. For those in between, it was better. The new model reclassified almost half of these women into high- risk and low-risk groups. The new assignments, done by computer, corresponded almost perfectly to what actually happened to these women over the next 10 years.

The team is now checking to see if the new risk tool works as well for men. The researchers have posted it at reynoldsriskscore/ for anyone to try.

Leahy and her colleagues Rolls, Leann Birch, Distinguished Professor of Human Development and Family Studies at Penn State University, and Jennifer Fisher, Assistant Professor of Pediatrics at Baylor College of Medicine in Houston, Texas, presented their findings today (May 1) at the Experimental Biology Conference in Washington, D.C.

When served the lower-calorie pasta, children consumed 17 percent fewer calories and ate significantly more vegetables, compared to the higher-calorie pasta. Results from preference tests also suggest that for the most part, the children showed no clear preference for either dish.

The fact that we got the reduction in caloric intake is absolutely great," said Rolls. "And the increase in vegetable intake suggests a strategy for improving diet quality," she added.

Leahy, however, notes that parents should still actively promote the consumption of vegetables by serving them regularly and eating them with their children. "You not only want to increase their vegetable intake but also want to ensure that your kids will acquire a taste for vegetables," she added.
