Abstrakt:	Iron deficiency and iron deficiency anaemia are frequently under-recognised in chronic conditions with non-specific symptoms, including fatigue. This study aimed to assess the prevalence of iron deficiency with or without anaemia in chronic pain patients, and the association between iron deficiency status, fatigue and health-related quality of life. Eighty-two patients attending chronic pain outpatient appointments were recruited into this cross-sectional study. Iron studies and haemoglobin were determined from venous blood samples. Participants' health-related quality of life was assessed with the 36-item short form survey and fatigue with the functional assessment of chronic illness therapy fatigue scale. Iron deficiency was prevalent in 58.8% of patients and 2.5% met the criteria for iron deficiency anaemia. There was no significant association between iron deficiency status and the functional assessment of chronic illness therapy fatigue scale score or 36-item short form survey domain scores. There was a high prevalence of iron deficiency in this group of chronic pain patients, while the prevalence of iron deficiency anaemia was low. There was no statistically significant association found between iron deficiency status and fatigue or quality of life measures.
