OBJECTIVE: Low plasma (p)-albumin and p-calcium concentrations are associated with increased mortality in hospitalised patients. There are few studies addressing this in primary care. Low p-calcium has been associated with mortality, but it is not known whether this applies to p-albumin. Could p-albumin and p-calcium be used as markers of an increased risk of mortality? PURPOSE: To study p-albumin and p-calcium at baseline and their association with mortality after 10-14 years. DESIGN: Prospective cohort study using data from a large primary health care area and the National Swedish Cause of Death Register. SETTING: Primary health care in Skaraborg, Sweden. SUBJECTS: 43,052 patients (39.1% men), ≥18 years, 60.7 ± 18.4 years with p-albumin and p-calcium concentrations registered in 2001-2005. MAIN OUTCOME MEASURES: P-albumin and p-calcium concentrations at baseline and their association with mortality after a mean follow-up period of 10.3 ± 4.0 years. RESULTS: Low p-albumin was associated with total mortality compared with normal p-albumin, greatest at lower ages (18-47 years). The hazard ratios for women and men were 3.12 (95% CI 1.27-7.70) and 4.09 (95% CI 1.50-11.14), respectively. The increased mortality was seen in both cardiovascular and malignant diseases in both women and men. In contrast, low p-calcium was not associated with increased mortality, 1.00 (95% CI 0.96-1.05). Elevated p-calcium was associated with increased mortality, 1.17 (95% CI 1.13-1.22). CONCLUSIONS: ...
