Blood Folate and Vitamin B12: United States, 1988-94. 84 pp. (PHS)
99-1693. GPO stock number and price forthcoming A new report from the National Center for Health Statistics, Centers for Disease Control and Prevention shows the distribution of concentrations of serum and red blood cell folate and presents the first national estimates of serum vitamin B12 for the U.S. population. These measurements of the amount of vitamins in the blood are important because of the link between inadequate folate in pregnant women and neural tube defects in newborns and a potential association of folate, B12 and other B vitamins with the risk for cardiovascular disease and certain cancers. Reference data in this report will be used to establish and evaluate nutrition policies such as the impact of the recently enacted food fortification policies. Major findings in the report show:
"Blood Folate and Vitamin B12: United States, 1988-94" presents national estimates of serum and red blood cell folate and serum vitamin B12 distributions for persons 4 years of age and over by sociodemographic variables, including sex, age, race, ethnicity, poverty and education levels. Data were collected in the third National Health and Nutrition Examination Survey through interviews, physical examination and standardized laboratory tests. Data were collected and analyzed by the National Center for Health Statistics in collaboration with the National Center for Environmental Health and the National Center for Chronic Disease Prevention and Health Promotion, all of the Centers for Disease Control and Prevention.
