AI Insight
A cross-sectional community screening study conducted in Puducherry, South India, found that 96.7% of eligible adults (264 out of 273) accepted integrated HIV and tuberculosis screening at health camp-style events, nearly double the pre-specified acceptability threshold of 50%. Participants were predominantly low-income with limited prior testing history, and the most commonly reported motivation was simply wanting to know their health status. While uptake was high across demographic groups, younger men were substantially underrepresented relative to their share of the general population, a concern given that TB incidence in India peaks in the 15 to 45 age group and disproportionately affects men.
Why it matters
These findings challenge the widespread assumption that community-based HIV screening would be poorly accepted in India due to stigma, suggesting that low testing rates reflect unmet demand rather than reluctance. Scaling up integrated HIV-TB community screening could meaningfully accelerate progress toward TB elimination in high-burden settings, provided that targeted strategies are developed to reach younger men and underserved subgroups.

Background: Despite rising enthusiasm for active case-finding for TB, there have been concerns about conducting simultaneous HIV screenings due to perceived stigma, although the evidence to support this concern is scarce. We assessed the acceptability of integrated HIV-TB community screening and characterised participants’ motivations and prior testing history. Methods: The SLIM study was a non-interventional cross-sectional study conducted in Puducherry (February 2023 to January 2024). In two community health camp-style screening events (one urban and one peri-urban), adults 18 years and older were offered TB screening via portable chest X-ray with AI-assisted interpretation (qXR, Qure.ai), plus sputum testing (Truenat), alongside point-of-care HIV testing. Structured questionnaires captured sociodemographics, prior testing history, and motivations for participation. Acceptability was pre-specified as >50% uptake. Results: Of 273 eligible adults approached, 264 (96.7%) accepted integrated screening, nearly double our pre-specified threshold. Participants were predominantly low-income with limited formal employment. The dominant motivation was a desire to know one’s health status (HIV: 74.8%; TB: 73.7%), followed by convenience (16 to 17%). Prior HIV and TB testing was rare (7 to 13% and 15 to 18%, respectively). Participation was uniformly high across demographic groups; however, the screened population skewed older and female (mean age 58 (standard deviation: 12.6) years; 67% female). Men under 45 comprised only 3.7% of participants, substantially below their 24.7% share in the Puducherry population per the most recent census. Conclusions: Integrated HIV-TB screening achieved near-universal uptake in a socioeconomically vulnerable population with little prior testing exposure, contradicting concerns that community HIV screening would be poorly accepted in India. Integrated community-based screening should be scaled up as a cornerstone of TB elimination in high-burden settings. Crucially, because TB incidence in India peaks in the 15 to 45 age group and disproportionately affects men, targeted strategies to bring younger men and women into community screenings are essential.
