Objectives: To provide a reference range for plasma total homocysteine (tHcy), an independent risk factor for vascular disease, and to explore relationships with nutritional indices for people aged 65 y and over, in the UK National Diet and Nutrition Survey (NDNS).Design: The survey procedures described in the National Diet and Nutrition Survey Report (1997) included a health-and-lifestyle interview, a four-day weighed diet record, anthropometric and blood pressure measurements and a fasting blood sample for biochemical indices, including tHcy.Setting: Eighty randomly selected postcode sectors from mainland Britain during 1995-1996.Subjects: Of 2060 people interviewed, 1527 were visited by the nurse, 1276 gave a blood sample and 972 had tHcy measured. About 80% were in their own homes and the remainder were in nursing homes or similar institutions.Results: Significant cross-sectional relationships, both univariate and multivariate were found between tHcy and index concentrations of folate and vitamin B-12 (P < 0.0001), and between tHcy and plasma creatinine, urea, calcium, zinc, alpha(1)-antichymotrypsin, lutein and cysteine (P = 0.013 to < 0.0001). Dietary nutrient analyses showed an association with folate intake. tHcy was also correlated with age and with domicile (free-living or institution), with history of vascular disease and with use of four classes of drugs, two of which are prescribed for vascular diseases. There was a north-south gradient in tHcy (P = 0.005), and also in food choices, blood micronutrient indices and vascular disease prevalence.Conclusions: The concentrations of tHcy found in this study provide a reference range for people aged 65 y and over, in mainland Britain. tHcy is a valuable functional index of micronutrient status and intakes for British people aged 65 y and over, which can assist the development of health-promotion strategies.
