However, it is unknown if NAID is associated with increased mortality in older adults. A nationally representative sample of 4451 older adults from the English Longitudinal Study of Ageing was used. NAID was defined as serum ferritin\u00a0&lt;\u00a030\u00a0\u03bcg\/l and haemoglobin\u00a0\u2265\u00a0120\u00a0g\/l (women) or\u00a0\u2265\u00a0130\u00a0g\/l (men). Cumulative mortality was estimated by Kaplan\u2013Meier method. Unadjusted and adjusted hazard ratios (HRs) of mortality were calculated using Cox proportional hazards regression models. Baseline NAID prevalence was 8\u00b78% (95% confidence interval [CI] 8\u00b70\u20139\u00b77%); 10\u00b79% (95% CI 9\u00b77\u201312\u00b73%) for women and 6\u00b735% for men (95% CI 5\u00b73\u20137\u00b75%). The HR for mortality for individuals with NAID compared with non\u2010anaemic individuals without iron deficiency over the 14\u2010year follow\u2010up was 1\u00b758 (95% CI 1\u00b729\u20131\u00b793). This association was independent of all identified demographic, health\u2010related and biological covariates, and robust in multiple sensitivity analyses. In older adults in England, NAID is common and associated with an increased mortality rate compared to non\u2010anaemic individuals with normal serum ferritin. The association is principally driven by an excess mortality in women.<\/jats:p>","DOI":"10.1111\/bjh.16409","type":"journal-article","created":{"date-parts":[[2020,2,19]],"date-time":"2020-02-19T03:42:15Z","timestamp":1582083735000},"page":"566-572","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["The prevalence and associated mortality of non\u2010anaemic iron deficiency in older adults: a 14 years observational cohort study"],"prefix":"10.1111","volume":"189","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9614-3580","authenticated-orcid":false,"given":"Keir E.
