What can explain why the rate of teen pregnancy has dropped dramatically? As the Christian Science Monitor explains it:
After rising between 2005 and 2007, the US teen birthrate fell dramatically in 2009. What happened? For one, MTV began airing a tough reality show called '16 and Pregnant.'
Parents still remain the most important influence for avoiding teenage pregnancy. A report released Tuesday by the National Campaign to Prevent Teen and Unplanned Pregnancy also credits Bristol Palin for introducing a dose of reality.
