Sexual risk factors and viremia at baseline and follow-up.
| Full baseline sample (N = 1046) | Follow-up sample (n = 979) | |
| Variables contributing to outcome measure | N (%) | N (%) |
| Sexual risk factors | ||
| Transactional sex | 68 (6.5%) | 73 (7.5%) |
| Sex with older partner | 26 (2.5%) | 60 (6.1%) |
| Unprotected sex | 65 (6.2%) | 91 (9.3%) |
| Multiple sexual partners | 91 (8.7%) | 134 (13.7%) |
| Pregnancy | 75 (7.2%) | 98 (10.0%) |
| Any sexual risk (combined) | 158 (15.1%) | 271 (27.7%) |
| Treatment-related outcomes | ||
| Detectable viral load (>200 copies/ml)b | 167 (29.0%) | 146 (28.0%) |
| Detectable viral load (>1500 copies/ml)b | 124 (23.0%) | 98 (18.8%) |
| Past-week nonadherence | 365 (34.9%) | 348 (35.6%) |
| Viraemia a | 318 (30.4%) | 288 (29.4%) |
| Secondary HIV transmission riskc | ||
| Sexual risk and viremia | 70 (6.7%) | 110 (11.2%) |
| Low risk (no risk at baseline nor follow-up) | 840 (85.8%) | |
| High-risk group | 139 (14.2%) | |
a
Combination of past-week nonadherence for those without VL record and detectable viral load (>1500 copies/ml) for those with VL record.
b
Viral load data were available for 540 at baseline and 522 at follow-up. Frequencies of detectable viral load computed on available data.
c
Secondary HIV transmission riskc computed as participants reporting both sexual risk and viremia at each time point.
