Objectives To assess the relationship between hemoglobin concentration and cause-specific mortality. Design Cohort study. Setting Data from the government-sponsored Annual Geriatric Health Examination Program. Participants Community-dwelling Taipei citizens aged 65 and older followed up between 2006 and 2010 (N = 77,532). Measurements Mortality was determined by matching participants' medical records with national death files. Cox proportional hazards regression models were used to evaluate the relationship between hemoglobin concentration (World Health Organization ( WHO)-defined anemia and 7 hemoglobin concentrations) and cause-specific mortality. Results The mortality risk of WHO-defined anemia increased substantially in both sexes for all-cause and cancer mortalities (men, hazard ratio ( HR) = 1.86, 95% confidence interval ( CI) = 1.71-2.02 for all-cause mortality; HR = 1.94, 95% CI = 1.69-2.22 for cancer mortality; for women, HR = 1.63, 95% CI = 1.43-1.86 for all-cause mortality; HR = 1.74, 95% CI = 1.38-2.19 for cancer mortality). Men with hemoglobin concentrations of 15.0 to 15.9 g/ dL and women with hemoglobin concentrations of 13.0 to 13.9 g/ dL had the lowest risks of all-cause, cardiovascular, and cancer mortality. Risks of all-cause and cancer mortality increased significantly when hemoglobin concentrations were less than 14 g/ dL in men and less than 12 g/ dL in women. Even mild anemia (11.0-11.9 g/ dL) was associated with greater mortality risk. Stratification according to age, body mass index, estimated glomerular filtration rate, and presence of comorbidities did not lead to any substantial changes. Conclusion Hemoglobin concentrations associated with optimal survival in older adults were identified and additional data provided regarding the relationship between hemoglobin concentrations and cause-specific mortality risks in older adults.

Objectives To estimate the all-cause, cardiovascular, and cancer mortality risks associated with serum uric acid levels in elderly adults. Design Cohort study. Setting The Annual Geriatric Health Examination Program database from 2006 to 2010. Paticipants Community-dwelling Taipei citizens aged 65 and older (N = 77,541). Measurements Stratified according to sex, serum uric acid levels were analyzed in quartiles and as normal versus high categories. Mortality was determined by matching cohort identifications with national death files. Results Men had significantly higher uric acid levels than women ( P < .001), and mean levels increased with age ( P < .001). Serum uric acid levels (normal vs high) were an independent risk factor for all-cause and cardiovascular mortality in men and women, with the strongest association found for cardiovascular mortality. The association between serum uric acid levels and cardiovascular mortality was independent of other cardiovascular risk factors such as hypertension, diabetes mellitus, hyperlipidemia, and glomerular filtration rate levels. When levels were analyzed as quartiles, men with levels in the second quartile had the lowest hazard ratios for all-cause and cardiovascular mortality. Conclusion High serum uric acid levels are associated with greater risk of all-cause and cardiovascular mortality but not cancer mortality in elderly adults. Further studies are warranted to investigate the prognostic implications and potential utility in the monitoring of therapy. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented which is concerned with a nationwide population based study in Taiwan that was concerned with alendronate and the risk of esophageal cancer.
