TUESDAY, Oct. 30 (HealthDay News) -- Teens with smartphones are more likely to have sex and meet others online for sex than teens without Internet access on their phones, according to a new study.
But it's not clear if the smartphone actually influences teenagers' sexual activity, and at least one critic of the research called it weak.

Forty-seven percent of these students said they were sexually active, compared to 35 percent of those who didn't own smartphones.
Seventeen percent of the smartphone users said they had had sex with someone they met online, compared to 14 percent of kids without smartphones, Rice said.

The study also doesn't prove that smartphones and sexual activity are connected, or look at whether be
