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).
