Body-confident women less likely to have unprotected sex

While I’ve had quite enough of studies talking about young people and all their risky sex (AMA, I’m talking to you!), I thought this one was worth checking out.
Apparently, young men who feel good about the way they look are more likely to have unprotected sex with multiple partners while young women with a positive body image were less likely to have risky sex. Interesting.

The men who were most satisfied with their appearance, and the most appearance-oriented — meaning they were highly invested in their looks and considered appearance to be important — were also the most likely to have sex without condoms and to have sex with multiple partners, Dr. Eva S. Lefkowitz of Pennsylvania State University in University Park and colleagues report.
…Among young women, in contrast, those with a more positive body image were less likely to engage in risky sexual behavior, Lefkowitz and her team found.

I think this is interesting stuff, but there’s a part of me that’s wary about an alternate conclusion that could be reached from this study–that women have “risky” sex if they have low self-esteem. If risky is defined as having multiple partners, the argument that women who “sleep around” actually just hate themselves isn’t exactly new.
Thoughts?
