Hazard Ratios (HRs) for the Association Between Recent Sexual Behaviors and Incident High-Risk Human Papillomavirus (HPV) Detection in All 420 Women Aged 25–65 Years

Variablea	Incident Detections, No.	Person-Years at Risk, No.	Incidence Rateb per 100 Person-Years (95% CI)	Unadjusted HR (95% CI)	Adjusted HR (95% CI)c
Not sexually active with a male partner	17	1632	1.04 (.65–1.68)	Reference (1.0)	Reference (1.0)
Sexually active with no high-riskd behavior	27	2253	1.20 (.82–1.75)	1.11 (.52–2.37)	1.19 (.53–2.68)
Sexually active with ≥1 high-riskd behavior	125	3946	3.17 (2.66–3.77)	2.87 (1.49–5.55)	2.81 (1.38–5.69)

Abbreviation: CI, confidence interval.

^a Composite variable for sexual risk behaviors in past 6 mo.

^b Average type-specific incidence rate.

^c Adjusted for current hormonal contraceptive use and marital status.

^d High-risk behaviors were defined as behaviors that were statistically significantly associated with incident high-risk HPV detection in women reporting ≥1 male partner in the past 6 months, as follows: reports of new male partners, reports of casual male partners, reports of partners with ≥1 concurrent partnership, and reports of ≥2 male partners (Table 4).
