 Q Are haemoglobin (Hb) concentrations associated with mortality risk in older, community dwelling women with disabilities? Clinical impact ratings GP/FP/Primary care ★★★★★★☆Haematology ★★★★☆☆☆ Geriatrics ★★★★★☆☆ Design: cohort study (Women’s Health and Aging Study I). Setting: Baltimore, Maryland, USA. Patients: 686 women ⩾65 years of age (mean age 78 y, 72% white), who had a Mini-Mental State Examination score ⩾18 and self reported difficulty performing activities in ⩾2 physical function domains. Risk factors: Hb concentrations. Outcomes: all cause mortality after a maximum of 6 years of follow up (median 5 y). Cumulative all cause mortality was 31%. A non-linear relation existed between Hb and mortality, with highest mortality risk at extreme Hb concentrations and lowest risk in intermediate Hb concentrations. Mildly low Hb concentrations … ER -
