The Effectiveness Of Sex Ed: A study published in the November/December issue of Family Planning Perspectives indicates that sex education classes are linked to behavioral changes that could lead to sexual abstention or effective use of contraceptives. The study surveyed 1,444 adolescents ages 13 to 19 who participated in publicly funded sex education programs in Texas and California. The research was funded by the National Institutes of Child Health and Human Development, two foundations, and the state of Texas.
