Plasma Homocysteine Distribution in the United States

Status Completed

Clinical Trial Summary

To describe the distribution of homocysteine and prevalence of hyperhomocysteinemia with emphasis on race, sex and age. To determine the extent to which hyperhomocysteinemia is associated with status of folate and vitamin B12. Finally, to describe the relationships between prevalence of hyperhomocysteinemia and prevalence of cardiovascular disease and assess the importance of this risk factor as a cause of vascular disease among US adults. The study was renewed for one year to investigate normal homocysteine concentrations among children and to identify nutritional and non-nutritional determinants of total homocysteine concentrations in children.

Clinical Trial Description

BACKGROUND:

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.

DESIGN NARRATIVE:

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.. ;
