RICHMOND, Nov. 12 — Virginia Gov. Timothy M. Kaine has cut off state funding for abstinence-only sex education programs, citing recent studies finding that teenagers should also be taught about birth control and condoms to protect against pregnancy and sexually transmitted diseases.
Kaine (D) submitted plans last month to close a budget shortfall in part by eliminating a $275,000 matching grant for a federal program that provided funds for 14 nonprofit groups that taught abstinence only.

Planned Parenthood of Virginia, which had lobbied for the change in policy, sent out a statement Monday praising Kaine for joining its nationwide campaign to eliminate abstinence-only programs, which urge youths to refrain from sex until marriage.
“There is no evidence that abstinence-only programs equip teens with the education they need to delay sexual activity or prevent unintended pregnancies or the spread of sexually transmitted disease,” said Becky Reid, an organizer for Planned Parenthood Health Systems.
