This article presents information related to a study focusing on the relation between hemoglobin (Hb) levels and mortality risk in older, community-dwelling women with disabilities. According to this, cumulative all-cause mortality was 31% in such women. A nonlinear relation existed between Hb and mortality, with highest mortality risk at extreme Hb levels and lowest risk in intermediate Hb levels. Mildly low Hb levels of 110 and 115 g/L were associated with greater mortality risk than an Hb level 120 g/L, even after controlling for major chronic disease burden indicators, whereas mid-normal Hb levels of 130 g/L and 140 g/L were associated with lower mortality risk.
