We estimated the risk of outcome associated with [U.sub.Na] using a Cox proportional hazard model. The effect of interaction of some variables on the relationship between [U.sub.Na] and survival was examined by adding a corresponding interaction term in the model.

In a log binomial analysis adjusted for factors such as socioeconomic status and educational attainment, female youth in the VIP program group had a greater risk than their counterparts in the control group of experiencing a pregnancy event by age 20 (relative risk, 1.4); the finding was the same in a Cox proportional hazard model that adjusted for the same factors.
