Objective: To determine the frequency of underlying risk factors and the socio-economic impact based on occupation in the development of tuberculosis. Method: Retrospective analysis of 207 clinically and microbiologically diagnosed patients with pulmonary tuberculosis (PTB) admitted to Kasturba Hospital in 2005 and 2006. Demographic details and underlying risk factors were statistically evaluated. Results: Diabetes mellitus (DM) (30.9%) was the most prevalent condition and significantly more common than other risk factors like smoking (16.9%), alcoholism (12.6%), HIV (10.6%), malignancy (5.8%), chronic liver diseases (3.9%), history of contact with TB (3.4%), chronic corticosteroid therapy (2.9%), chronic kidney diseases and malnourishment (1.5%). There were 82 patients (39.6%) with no underlying risk factor. Men (M:F = 3.7:1) and patients older than 40 years had a higher incidence of co-existing conditions. PTB was significantly more common in blue-collar (44%) and white-collar (27.1%) workers than household workers (12.1%), students (10.6%) and retired/unemployed people (6.3%). Conclusion: Pulmonary tuberculosis had a significant impact and predominated in male patients co-existing with DM. Patients with DM and suggestive pulmonary symptoms should be screened for tuberculosis. More stringent health education and awareness programme should be implemented at the grass root level.
