Assessment of subjective sleep quality in iron deficiency anaemia

Objectives: 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. Conclusion: IDA affects sleep quality irrespective of psychological symptoms such as depression and anxiety.
