According to the National Campaign to Prevent Teen and Unplanned Pregnancy, more than half -- 53 percent -- of Latinas get pregnant by their 20th birthday, nearly twice the national average. "There's a big disconnect between pregnancy rates and what Latina families want and value," said Ruthie Flores, senior manager of the National Campaign's Latino Initiative. Of the 759 Latino teens surveyed, 49 percent said their parents most influenced their decisions about sex, compared with 14 percent who cited friends. Three percent cited religious leaders, 2 percent teachers and 2 percent the media.
