Depression, anxiety and quality of life among diabetic patients: a comparative study.
OBJECTIVE
The aim of this study was to compare psychiatric morbidity among diabetic patients, asthmatics and healthy individuals and also to assess the association of psychiatric morbidity and other variables with quality of life among diabetes patients.


METHODS
For each respondent, the questionnaire on sociodemographic and clinical variables was completed. They also completed the Zung Self-Rating Depression Scale and the State Trait Anxiety Inventory (STAI 1). Diabetic patients also completed the Diabetic Well-Being Questionnaire.


RESULTS
A total of 180 subjects were used for this study-80 diabetics (males=37, females=43) were compared with 50 asthmatics (males=22, females=28) and 50 healthy individuals (males=23, females=27). Depression was more prevalent among diabetic patients (20%) compared with asthmatics (12%) and healthy individuals (4%), while anxiety was more prevalent among asthmatics (34%) compared with diabetics (20%) and healthy individuals (8%). Predictors of depression include age of the patient, poor glycemic control and duration of diabetes mellitus. Factors that correlated significantly with diabetic general well-being include depression, anxiety and fasting blood glucose level. Depression and the presence of comorbid medical conditions significantly predicted a low quality of life.


CONCLUSIONS
Psychiatric morbidity has significant effects on diabetic patients' quality of life.
