title: Assessment of subjective sleep quality in iron deficiency anaemia.
abstract: OBJECTIVE
  We aimed to assess the effect of anemia on subjective sleep quality in patients with iron deficiency anemia (IDA).
  
  
  METHODS
  One hundred and four patients diagnosed with IDA and 80 healthy individuals, who are gender and age matched, were included in the study. All participants were requested to fill 3 forms: a socio-demographic form (age, gender, marital status, income level and educational status), hospital anxiety and depression (HAD) scale and pittsburgh sleep quality index (PSQI).
  
  
  RESULTS
  According to the HAD scale, the average anxiety score was found 9.24±4.37 in patients and 7.58± 4.07 in controls. And, the average depression score was 7.53±4.10 in patients and 6.41±2.74 in controls. The total sleep quality score was 6.71±3.02 in patients and 4.11±1.64 in controls. There was a statistically significant difference in terms of anxiety, depression and sleep quality scores. Linear regression analysis showed no association between anxiety and depression with poor sleeping.
  
  
  CONCLUSIONS
  IDA affects sleep quality irrespective of psychological symptoms such as depression and anxiety.
