TABLE 2—

Factors Associated With Risk of Repeat Syphilis Infection Among Men Who Have Sex With Men (MSM) in Multivariable Analyses, by Stage of Syphilis at Repeat Diagnosis: California, 2004–2006

Stage at Repeat Diagnosis	HIV, AOR (95% CI)	Black Race, AOR (95% CI)	≥ 10 Sex Partners, AOR (95% CI)
Primary or secondary^a (n = 162^b)	1.65 (1.14, 2.37)	1.84 (1.12, 3.04)	1.98 (1.12, 3.50)
Primary, secondary or early latent^c (n = 300^b)	2.27 (1.70, 3.02)	1.39 (0.92, 2.10)	1.99 (1.30, 3.05)
Early latent^d (n = 138^b)	3.45 (2.19, 5.44)	0.88 (0.45, 1.71)	1.98 (1.08, 3.64)

Note. AOR = adjusted odds ratio; CI = confidence interval. Odds ratios were adjusted for region, race, HIV status, number of sex partners, and methamphetamine use.

^{^a}

Baseline group: 2862 interviewed MSM with an initial primary or secondary syphilis infection who did not have a repeat early latent syphilis infection.

^{^b}

Number of MSM reinfected within 2 years.

^{^c}

Baseline group: 3000 interviewed MSM with an initial primary or secondary syphilis infection.

^{^d}

Baseline group: 2838 interviewed MSM with an initial primary or secondary syphilis infection who did not have a repeat primary or secondary syphilis infection.
