The potential influence of a social media intervention on risky sexual behavior and Chlamydia incidence.

The purpose of this descriptive pilot study was to evaluate an evidence-based social-networking intervention aimed at reducing the incidence of Chlamydia among 15- to 24-year-olds. The intervention consists of a Facebook site that addresses signs, symptoms, treatment, screening, and prevention of Chlamydia infection. Findings included a 23% self-reported increase in condom utilization, and a 54% reduction in positive Chlamydia cases among 15- to 17-year-olds. Study results support that social media may be an effective mechanism for information dissemination and the promotion of positive behavioral changes among this population.
