HIV seropositivity among women and men presenting for VCT, by number of lifetime partners and age of tester in Moshi, Tanzania, 2003–2007.

<p>Among women, subjects between 30 and 39 years old had the highest risk of seropositivity in each category of lifetime sexual partners (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003075#pone-0003075-g002" target="_blank">Figure 2</a>, Panel A), while subjects 40 years or older had the greatest rise in risk of seropositivity with increasing numbers of sexual partners. The associations were similar but not as strong among men (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0003075#pone-0003075-g002" target="_blank">Figure 2</a>, Panel B). Non-parametric trend tests of associations between the number of partners and seropositivity were significant among men in the youngest and two oldest age groups only (p = 0.016; p = 0.035; and p = 0.001, respectively) and among women showed significant effects in all age groups (p<0.0001 to p = 0.006).</p
