Hyperhomocysteinemia, a condition of elevated plasma homocysteine concentrations resulting from impaired sulfur amino acid metabolism, may be a powerful risk factor for occlusive vascular disease. However, little is known about the distribution of hyperhomocysteinemia in the general population. Furthermore, inadequate nutritional status might be a strong determinant of hyperhomocysteinemia, but its importance at a population level (as measured by the prevalence of hyperhomocysteinemia associated with inadequate nutrition) has received little study. Finally, levels of homocysteine associated with elevated risk of vascular disease have not been clearly established.
Using previously collected plasma samples, studies were conducted on the distribution of homocysteine and prevalence of hyperhomocysteinemia with emphasis on race, sex and age. Investigations were undertaken on the extent of the relationship of hyperhomocysteinemia to folate and vitamin B12. Finally, the relationships were described between prevalence of hyperhomocysteinemia and prevalence of cardiovascular disease and the importance of this risk factor as a cause of vascular disease among US adults was assessed..
