Healio reported on a study concerning targeting prevention based on geographical areas with heavy concentrations of sexually transmitted infections (STIs). The researchers analyzed 1999-2010 data on adults ages 18-59 from the National Health and Nutrition Examination Survey. They used the 2006 CDC National Center for Health Statistics Urban-Rural Classification Scheme for Counties to determine urban classification of residences. They then investigated prevalence of HIV, herpes simplex virus type 2 (HSV-2), human papillomavirus (HPV), chlamydia, hepatitis B virus, and hepatitis C virus (HCV) based on level of urbanicity for the population, which was categorized into men who have sex with men (MSM), injection drug users, and heterosexuals.
Findings indicated a higher prevalence of HIV, HSV-2, and HPV in large metropolitan central areas. Incidence of HIV for MSM was higher in large central and large fringe metropolitan areas. Also, there was higher distribution of HSV-2, chlamydia, and HPV in heterosexuals for large central metropolitan areas. Urbanicity did not affect HPV and HCV incidence for any of the populations, including injection drug users.
The researchers concluded that the findings illustrate cultural differences that can be used to create targeted interventions for the different population groups.
The full report, "Prevalence of HIV, Sexually Transmitted Infections, and Viral Hepatitis by Urbanicity, Among Men Who Have Sex With Men, Injection Drug Users, and Heterosexuals in the United States," was published in the journal Sexually Transmitted Diseases (2014; 41(4):272-279).
