Chlamydia, gonorrhea, and trichomoniasis were tested at Wave III.
Survey commands accounted for stratification, clustering, and unequal selection probabilities yielded nationally representative estimates of White and Black young adults.
Personal use exposures (ever or current use) adjusted for age, maternal education, respondent’s low functional income at Wave III, adolescent alcohol use, adolescent delinquency, and age at first sexual intercourse; peer use adjusted for covariates and for personal report of ever use; peer use associations were measured controlling for personal use.
Gender interaction significant at the p<0.10 level.
