Analysis of Syndemic Variable Interaction for BMSM who did not Report HIV Screening in the Previous Six Months in the POWER Sample, 2014–2017 (n = 1,097)
| Odds Ratio Expected | Observed | RERI | AP | S | ||
|---|---|---|---|---|---|---|
| Poly-drug use | Depression | 1.39 | 1.41 | 0.02 | 0.01 | 1.02 |
| Poly-drug Use | Intimate Partner Violence | 1.60 | 1.00 | −0.59 | −0.59 | 0.01 |
| Depression | Intimate Partner Violence | 0.76 | 1.08 | 0.32 | 0.29 | −0.35 |
| Depression | Problematic Drinking | 1.07 | 1.27 | 0.20 | 0.16 | 3.70 |
| Depression | Sexual Risk | 0.75 | 0.93 | 0.18 | 0.20 | 0.28 |
| IPV | Sexual Risk | 0.74 | 0.72 | −0.01 | −0.02 | 1.06 |
| Intimate Partner Violence | Problematic Drinking | 1.00 | 0.91 | −0.09 | −0.10 | −29.49 |
| Sexual Risk | Problematic Drinking | 1.26 | 1.51 | 0.25 | 0.17 | 1.98 |
| Poly-drug use | Problematic Drinking | 1.07 | 1.27 | 0.20 | 0.16 | 3.70 |
Note: RERI: relative excess risk of the interaction; AP: attributable proportion of the relative excess risk of the interaction; S: synergy index; bold type indicates synergy between variable pairs; due to the low prevalence of poly-drug use in this sample, an analysis of joint effects and synergy between sexual risk and poly-drug use could not be completed.
