Prevalence of Depression and Anxiety in Adult Patients with β-Thalassemia Major and Intermedia

Abstract

Objective: To evaluate and compare the prevalence and risk factors for anxiety and depression in adults with β-thalassemia major (TM) and intermedia (TI).

Method: A cross-sectional study of TI and TM patients at a Chronic Care Center in Lebanon. A total of 80 patients agreed to participate (32 TI (median age 24 years) and 48 TM (median age 23 years)). The Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory (STAI) questionnaires were used to assess the depression and anxiety levels of patients, respectively. Data on patient demographics, clinical complications, and socioeconomic status were also collected.

Results: Patients with TM had a significantly longer median duration with a known thalassemia diagnosis than patients with TI (p < 0.001). A considerable proportion of patients had depression (35.0%), State (S)-anxiety (22.5%) or Trait (T)-anxiety (36.2%). Patients with TI had a higher median S-anxiety score compared with TM (p = 0.035), although the median T-anxiety and depression scores were similar. On linear regression analysis, the significant association between the thalassemia diagnosis (TM versus TI) and S-anxiety score (beta: 5.740; 95% CI: 0.201 to 11.278; p = 0.042) was no longer observed upon adjustment for the co-variate duration with a known thalassemia diagnosis (beta: 3.162; 95% CI: −2.949 to 9.274; p = 0.306).

Conclusions: A considerable proportion of adult patients with TM and TI show evidence of depression and anxiety. Patients with TI are more liable to state anxiety than TM patients of a similar age, which is attributed to a shorter duration of living with a thalassemia diagnosis.
