<<Disclaimer: Verify this information before applying it to your situation.>> When the readers of this listserv group recently expressed an interest in the question of whether or not celiac disease/gluten intolerance seems to strike one blood type more than the others, I offered to collect and analyze the data in order to determine how our blood types compared to the known percentages in the normal population. I asked that anyone with celiac disease or gluten intolerance drop me an email message telling me their blood type. I received 113 responses and have just finished the analyses. Based on the statistical procedure I used (Chi Square analysis), there appears to be a very slightly increased proportion of gluten intolerant persons with B negative blood type. [Chi Square (7,N=113)=19.68, p<.01]. I want to caution you, however, that this was a totally uncontrolled survey. No distinction was made between those with confirmed celiac disease and those with self-diagnosed gluten intolerance, no checks were made on reported blood type, and the numbers of cases reported in some of the rarer blood groups (B+, AB+, AB-) was less than 5. There were 6 reported cases of B- blood type. If anyone would like a copy of the original data along with my Chi Square analyses, contact me by email. BJ
