Background and objectives
Understanding the drivers for care-seeking among those who present with symptoms of TB is crucial for early diagnosis of TB and prompt treatment, which will in turn halt further TB transmission. While TB is a challenge among the tribal population, little is known about the care-seeking behaviour and the factors influencing care-seeking behaviour among the tribal population across India.

Methodology
This community-based descriptive study was carried out in 17 states of India across 6 zones, covering 88 villages from tribal districts with over 70% tribal population. The sample population included individuals ≥15 years old who were screened through an interview for symptoms suggestive of pulmonary TB (PTB), currently and/or previously on anti-TB treatment. Those with symptoms were then assessed on their health-seeking behavior using a semi-structured interview schedule.

Results
Among 74532 eligible participants screened for symptoms suggestive of TB, 2675 (3.6%) were found to be presumptive TB cases. Of them, 659 (24.6%) sought care for their symptoms. While 48.2% sought care after a week, 19.3% sought care after one month or more, with no significant difference in the first point of care; 46.9% approaching a private and 46.7% a public facility. The significant factors influencing care-seeking behaviour were knowledge on TB (OR: 4.64 (3.70–5.83), p < 0.001), age<35 years (OR: 1.60 (1.28–2.00), p < 0.001), co-morbidities like asthma (OR: 1.80 (1.38–2.35), p < 0.001) and blood pressure (OR: 2.59 (1.75–3.85), p < 0.001), symptoms such as blood in sputum (OR: 1.69 (1.32–2.16), p < 0.001), shortness of breath (OR: 1.43 (1.19–1.72), p < 0.001) and weight loss (OR: 1.59 (1.33–1.89), p < 0.001). The cough was the most often reported symptom overall. There were gender differences in symptoms that prompted care-seeking: Males were more likely to seek care for weight loss (OR: 1.78 (1.42–2.23), p<0.001), blood in the sputum (OR: 1.69 (1.25–2.28), p<0.001), shortness of breath (OR: 1.49 (1.18–1.88), p<0.001) and fever (OR: 1.32 (1.05–1.65), p = 0.018). Females were more likely to seek care for blood in sputum (OR: 1.68 (1.10–2.58), p = 0.018) and shortness of breath (OR = 1.35, (1.01–1.82), p = 0.048). The cough did not feature as a significant symptom that prompted care-seeking.

Conclusion
Delayed healthcare-seeking behaviour among those with symptoms presumptive of TB in the tribal population is a major concern. Findings point to differences across gender about symptoms that prompt care-seeking in this population. Gender-sensitive interventions with health system strengthening are urgently needed to facilitate early diagnosis and treatment among this population.
