A new study by the New York City Department of Health and Mental Hygiene has found that 40 percent of New Yorkers engage in unprotected sex with multiple partners, WCBS-TV reports (wcbstv.com, 6/25).

According to the article, the survey of 10,000 adults living in New York City’s five boroughs found that although the city has distributed about 48 million condoms since last year, many aren’t using them. The study also found that men were three times more likely than women to report multiple partners.

The article reports that the health department is using public service announcements to encourage people to use condoms.
