Depression and anxiety among tuberculosis patients at a tuberculosis Unit in Bangalore

Tuberculosis (TB) remains a major public health challenge globally, particularly in low- and middle-income countries. Mental health disorders such as depression and anxiety are increasingly recognized as important comorbidities among TB patients, adversely affecting treatment adherence and outcomes. To estimate the proportion of depression and anxiety among tuberculosis patients attending a Tuberculosis Unit in Bangalore and to determine associated factors. A cross-sectional study was conducted among 66 adult TB patients at the Yeswanthpur TU, Bangalore. Depression and anxiety were assessed using PHQ-9 and GAD-7 scales. Data were analysed using descriptive statistics and Chi-square/Fisher’s exact test. The median age of study participants was 41 years (IQR: 29–43), and 71% were males. Symptoms suggestive of depression (PHQ-9 ≥ 5) were present in 51 participants (77.3%), with 31 participants (46.9%) having moderate to severe depression warranting clinical evaluation. Symptoms suggestive of anxiety (GAD-7 ≥ 5) were observed in 62 participants (94.0%), and 37 participants (56.1%) had moderate to severe anxiety. Anxiety was significantly associated with non-diabetic status. A high burden of depression and anxiety was observed among TB patients. Integrating routine mental health screening and appropriate evaluation into TB care services is essential to improve treatment outcomes and overall well-being.
