TABLE 3.
GEE Model-Based Significance Tests and Effect-Size Estimates for Intervention Effect on Adolescents' Self-Reported Sexual Behavior Over a 12-Month Follow-Up Period: Philadelphia, PA, and New Jersey, 1998–2002
| Outcome | Estimate | P |
| Consistent condom use in prior 3 mo,a OR (95% CI) | 1.39 (1.06, 1.84) | .02 |
| Proportion of protected sexual intercourse, % (95% CI) | 0.06 (0.00, 0.12) | .04 |
| Rated frequency of condom use,b mean difference (95% CI) | 0.20 (0.02, 0.39) | .03 |
| Condom use at last sexual intercourse,a OR (95% CI) | 1.29 (1.00, 1.67) | .05 |
| Frequency of sexual intercourse, event rate ratio (95% CI) | 1.06 (0.88, 1.28) | .56 |
Note. CI = confidence interval; GEE = generalized estimating equation.
a
OR for intervention versus health control.
b
Frequency of condom use was rated on a scale from 1 = never to 5 = always.
