Symptoms of Anxiety and Depression Among Teens and Adults in the Thalassemia Longitudinal Cohort Study.

Résumé
Abstract Abstract 555 Background and Significance: Individuals with chronic medical conditions are vulnerable to symptoms of anxiety and depression. Promoting healthy emotional functioning is important not only to psychological well-being, but also to physical health as it has been shown to impact adherence to medical regimens. Thalassemia is an inherited blood disorder which requires lifelong intervention and may be associated with treatment and disease-related complications that impact both the length and quality of life for most who are affected. While several studies have examined the prevalence of anxiety and depressive symptoms in patients with thalassemia, most have been conducted with small, homogeneous samples of children. In addition, the one study which examined psychological adjustment in adults included patients from only one medical center (Messina et al.; Intern Emerg Med, 3:339, 2008). Further, few studies have examined demographic, medical, and psychosocial variables possibly correlated with the occurrence of these symptoms. Understanding the factors that are related to the experience of depressive and anxiety symptoms may help us to identity individuals at risk and help in developing targeted interventions. The current study aimed to (1) determine the prevalence of depressive and anxiety symptoms in adolescent and adult patients with thalassemia; and (2) explore possible demographic, medical, and psychosocial correlates of these symptoms. Specifically, we hypothesized that (1) anxiety and depressive symptoms in this sample would be similar to the rates of these symptoms in individuals diagnosed with other chronic medical conditions and higher than in individuals without chronic medical conditions; (2) symptoms of depression and anxiety would be inversely correlated with measures of adherence (i.e., subjective report, ferritin); and (3) symptoms of depression and anxiety would be inversely correlated with functional health and well-being. Method: Data on quality of life and mental health self assessments were collected as part of the Thalassemia Longitudinal Cohort (TLC), a multi-center multinational study conducted by the NHLBI-sponsored Thalassemia Clinical Research Network. The current analysis included 281 participants (14-58 years old, M age=27.83; 52% female) who completed the Hospital Anxiety and Depression Scale (HADS), a 14-item questionnaire examining presence of anxiety and depression symptoms. Participants also completed a measure of functional health and well-being (SF-36), as well as questions related to adherence to their medical regimen. In addition, as part of the larger TLC study, medical data such as ferritin and method of chelation was collected. Results: 32% of participants indicated experiencing at least mild symptoms of anxiety and 11% at least mild symptoms of depression. While these rates are higher than rates of symptoms of depression and anxiety found in the general population, they are similar to rates found in other groups with chronic illness (e.g., diabetes). Older age, female gender, and chelation with deferoxamine (as compared to deferasirox) were factors that were significantly associated with anxiety and/or depression and were statistically controlled for in subsequent analyses. Symptoms of depression, but not anxiety, were inversely correlated with subjective reports of adherence (p<.05), although not with ferritin levels. However, a significant correlation in the expected direction between subjective report of adherence and ferritin was found (p<.01). Finally, as hypothesized, both symptoms of depression and anxiety were significantly and negatively correlated with functional health and well-being (p<.0001). Conclusion: While the majority of patients with thalassemia do not report significant symptoms of anxiety and depression, the rates are higher than in the general population. Given that symptoms of anxiety and depression were associated with poor adherence and lower functional health and well-being, regular screening for anxiety and depression symptoms could help to identify at risk individuals in order to provide them with appropriate psychological support with the goal of improving both emotional and physical health.

Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
