To date, there have been no studies evaluating the association between folic acid consumption or folic acid levels, and reduction in peptic ulcers. It might be possible that the mechanism of action of folic acid on amino acid and DNA synthesis might help cells regenerate and act protectively against peptic ulcers. The objective of this project is to evaluate the association between the level of red blood cell folic acid and a history of peptic ulcers using the National Health and Nutrition Examination Survey (NHANES) database from the years 1999-2000. 000000850 540__ $$fCC BY 000000850 542__ $$fIn copyright - single owner 000000850 650__ $$aErythrocytes$$018612 000000850 650__ $$aNutrition Surveys$$023102 000000850 650__ $$aPeptic Ulcer$$023751 000000850 650__ $$aFolic Acid$$019158 000000850 650__ $$aDNA$$017977 000000850 650__ $$aAmino Acids$$014562 000000850 650__ $$aFolic Acid$$019158 000000850 650__ $$aHealth Care Costs$$029646 000000850 650__ $$aNutrition Surveys$$023102 000000850 650__ $$aPeptic Ulcer$$023751 000000850 651__ $$aUnited States$$041167 000000850 6531_ $$anhanes 000000850 6531_ $$anational health and nutrition examination survey 000000850 691__ $$aSchool of Medicine$$041369 000000850 692__ $$aDepartment of Public Health and Preventive Medicine$$041444 000000850 7001_ $$aCamacho, Fernando$$uOregon Health and Science University$$041354 000000850 7201_ $$aThuillier, Phillippe$$uOregon Health and Science University$$041354$$7Personal$$eMentor 000000850 7201_ $$aBecker, Thomas$$uOregon Health and Science University$$041354$$7Personal$$eCommittee member 000000850 7201_ $$aMori, Motomi$$uOregon Health and Science University$$041354$$7Personal$$eCommittee member 000000850 7201_ $$aHartung, Daniel$$uOregon Health and Science University$$041354$$7Personal$$eCommittee member 000000850 7201_ $$aSrikanth, Priya$$uOregon Health and Science University$$041354$$7Personal$$eCommittee member 000000850 8564_ $$963f35014-3301-4acb-8598-b548c2e64634$$s2434790$$uhttps://digitalcollections.ohsu.edu/record/850/files/853_etd.pdf 000000850 905__ $$a/rest/prod/d7/91/sg/19/d791sg19j 000000850 909CO $$ooai:digitalcollections.ohsu.edu:850$$pstudent-work 000000850 980__ $$aTheses and Dissertations
