All models used for analysis included clusters as random effect.
Information about VCT acceptance was missing in 11 (0.7%) of the 1652 participants who were offered VCT.
After multivariate analysis, factors independently associated with the acceptance of HIV VCT residing in Uganda (aOR = 4.54, 95% CI: 1.17 to 17.62) and having another contact of the same index patient tested for HIV (aOR = 9.22, 95% CI: 5.25 to 16.18). Adults as compared with children (aOR = 0.35, 95% CI: 0.22 to 0.55, P < 0.001), being a contact of a HIV-positive index patient (aOR = 0.56, 95% CI: 0.38 to 0.83) and contacts needing a reassessment TB screening visit (aOR = 0.20, 95% CI: 0.06 to 0.67) were less likely to accept HIV VCT.
