Results of multivariate polytomous regression of HCV risk factors by level of risk from drug equipment borrowing (n = 176)
| No risk adjusted OR | Low/intermediate risk adjusted OR (95% CI) | High risk adjusted OR (95% CI) | |
|---|---|---|---|
| Age < 30 years (vs. ≥ 30 years) | 1.00 | 0.92 (0.36–2.36) | 0.43 (0.14–1.32) |
| Male (vs. female) | 1.00 | 1.13 (0.42–3.04) | 0.82 (0.28–2.39) |
| HCV positive (vs. HCV negative status) status | 1.00 | 0.84 (0.35–2.01) | 1.93 (0.69–5.38) |
| Asked someone to obtain sterile syringes from an SEPa | 1.00 | 2.50 (1.05–5.95) | 3.70 (1.42–9.71) |
| Problems obtaining sterile injecting equipment from an SEPa | 1.00 | 15.87 (3.80–66.67) | 21.74 (4.57–100.00) |
| Poor/average (vs. good/excellent) self-rated physical health | 1.00 | 2.39 (1.02–5.61) | 5.14 (1.87–14.13) |
| Cocaine (vs. heroin) injecting | 1.00 | 1.41 (0.49–4.08) | 1.76 (0.44–6.96) |
| Size of noninjecting social network (per member)a | 1.00 | 0.55 (0.38–0.79) | 0.84 (0.61–1.17) |
Note: Final model adjusted for age, gender, and the drug most commonly injected, as shown. Significant results shown in bold. No risk refers to no material sharing when injecting in the past 6 months (referent group); low/intermediate risk refers to sharing of at most nonsyringe materials (container, filter, water, postinjection swab, tourniquet); high risk refers to sharing of at least syringes.
