Sexually Transmitted Infection Risk among Women Is Not Fully Explained by Partner Numbers

摘要

Objectives Increased sexual partner numbers may contribute to sexually transmitted infection (STI) risk for some but not all women. This study compared women reporting having four or more partners during the preceding year (multiple partnership group) with those reporting having one partner (single partnership group) with regard to sexually risky behaviors and other modifiable predictors of STI risk. We also compared the prevalence of bacterial vaginosis, trichomoniasis, chlamydia, gonorrhea, syphilis, herpes simplex virus type 2, and human immunodeficiency virus among groups.
