(1) Half of youth who reported in Wave 1 that they had committed themselves to remaining abstinent until marriage reported no such commitment when interviewed again roughly a year later.
Add Health is based on a nationally representative sample of youth who were in grades 7-12 at Wave 1 (in 1995).
In the multivariate analysis, the odds of re traction were significantly elevated among males (odds ratio, 1.8), blacks (1.6), youth who had reported sexual experience at Wave 1 (3.2) and those who had experienced first intercourse between survey waves (3.2); the odds were reduced among adolescents who said that they answered sensitive survey questions honestly (0.5).
Thirty-three percent of teenagers reported in Wave 1 that they had ever had intercourse, but the following year, one in 10 of these (4% overall) said that they were sexually inexperienced.
To examine the factors underlying previously established links between residential mobility and adolescents' initiation of premarital sexual activity, researchers analyzed data from Add Health respondents who reported being sexually inexperienced at Wave 1 (conducted in 1994-1995) and had not married by Wave 2 (1996).
Those who had moved were younger than others at Wave 1 (14.3 vs.
In an initial logistic regression model, controlling only for teenagers' background characteristics, youth reporting a recent move at Wave 1 had a significantly elevated likelihood of beginning to have sex by Wave 2 (odds ratio, 1.4).
Similarly, in the model controlling for the behavior of teenagers' friends, youth who had moved shortly before Wave 1 did not have an elevated likelihood of beginning to have intercourse; sexual initiation was positively associated with peers' delinquency and inversely associated with their grade point average.
