a
N = 129
b
Multivariate analyses were used to control for time since enrolment in the cohort, as high-risk behaviours have previously been shown to decrease over time among women in the Mombasa cohort [14, 15].
c
Multivariate analyses were used to control for number of years since enrolment in the cohort, calendar year category (1993-1996, 1997-2000, 2001-2004, and 2005-2008), age (time varying), and any contraceptive use (time varying).
d
Analyzed only among women reporting any sexual activity (N=1,343 Pre-Art visits and N=1,317 After ART visits).
