Summary: induced mortality (22). Death rates are partic-
ularly high in individuals with high numbers of
lifetime sexual partners, and their death de-
creases the variance in reported numbers of
sexual partners. This in turn, alters the sexual
network through which HIV infection spreads
within the population (23), for example, by
forcing young women disposed toward forming
relationships with older men to choose younger
partners or abstain. In the current study, the
individuals who died during the intersurvey
period had reported higher numbers of lifetime
sexual partners at baseline than those who
survived to be reinterviewed (men: mean, 13.6
versus 8.7, P 0 0.001; women: mean, 3.0 versus
2.0, P G 0.001). Given the relatively small
numbers of individuals who died, AIDS-
associated mortality explained only 6.3% of
the observed reduction in sexual partner change
in men and 8.6% in women, but it cannot be
