Biochemical risk indices, including plasma homocysteine, that prospectively predict mortality in older British people: the National Diet and Nutritio…

Predictive power, for total and vascular mortality, of selected indices measured at baseline in the British National Diet and Nutrition Survey (community-living subset) of People Aged 65 Years and Over was tested. Mortality status and its primary and underlying causes were recorded for 1100 (mean age 76·7 (sd7·5) years, 50·2 % females) respondents from the baseline survey in 1994–5 until September 2008. Follow-up data analyses focussed especially on known predictors of vascular disease risk, together with intakes and status indices of selected nutrients known to affect, or to be affected by, these predictors. Total mortality was significantly predicted by hazard ratios of baseline plasma co…
