11% of Men Have Multiple Sex Partners
Pattern Raises HIV Risk, Researchers Warn
Oct. 31, 2007 -- Eleven percent of U.S. men have concurrent sex partners,
meaning they are in more than one sexual relationship at a time, a new study
The study, published online in the American Journal of Public Health,
is based on a CDC study conducted from March 2002 through March 2003.
More than 4,900 men ages 15-44 participated in telephone interviews about
their sex lives, including the dates during which they were in sexual
relationships in the previous year.
Concurrent sexual relationships were particularly common among these
- Unmarried men
- Men who had been in prison
- Men who reported being intoxicated while having sex
- Men who have had sex with men
- Men with female sex partners who had concurrent sexual relationships of
That mix may put those men -- and their partners -- at higher risk of
contracting HIV, the virus that causes AIDS.
African-American and Hispanic men were more likely than white men to report
concurrent sexual relationships.
But in all ethnic groups, most men had "no more than one sexual
partner" in the previous year," write Adaora Adimora, MD, MPH, and
colleagues, who work at the University of North Carolina School of Medicine in
Chapel Hill, N.C.
