Prevalence and risk factors associated with STIs among women initiating contraceptive implants in Kingston, Jamaica

This paper examines the prevalence of sexually transmitted infections (STIs) as a part of the Sino-implant (II) study, a trial in Kingston, Jamaica, that evaluated whether the initiation of the implant led to more unprotected sex among women ages 18 to 44 years. The authors found that the immediate initiation of Sino-implant (II) was not associated with higher STI prevalence rates over three months for these women. These findings fill an important gap in the evidence regarding the effect of initiation of long-acting reversible contraceptives on STIs.
