This technology reduces the risk of accidental disclosure to the interviewer, improves privacy, and may reduce nonresponse and increase reporting of sensitive or stigmatized behaviors 39 Young adults aged 18—24 years report much higher annual rates of STI than older adults and carry a heavy disease burden 15 Furthermore, a detailed sensitivity analysis of potential systematic differences between persons who did and did not provide a urine specimen in wave 3 found that conclusions regarding chlamydial infection prevalence were robust to differences in nonrespondent characteristics Results From Cohort and Sibling Analyses. Multivariate analyses examined the associations between family and individual characteristics and having a first sexual experience before age 16 with an older partner, and between age and partners' age difference at first sex and contraceptive use and having or fathering a child as a teenager. Time as the integrative factor. Rindfuss and Barbara Entwisle for their assistance in the original study design.
When examined in 1-year age increments, the STI prevalence for all current ages was above 5 percent.
Young teenagers and older sexual partners: correlates and consequences for males and females.
Thus, earlier first sexual intercourse is strongly associated with STIs for older adolescents but not for young adults over age 23, at which point the association becomes nonsignificant. With regard to sexual behavior, adolescents develop elaborate sets of ideas concerning sexuality and their sexual roles well before they actually engage in sexual activity While the focus on females in past research may have been driven in part by data availability, it can also lead to the misconception that the timing of first intercourse is less important for males in terms of their sexual risk trajectories. Though some research points to sexting as a potentially low-risk way to explore sexuality, it also is associated with increased risk of ostracism, depression, and suicide. Recent analyses of nonresponse in wave 3 of Add Health suggest that potential bias due to loss to follow-up is small Furthermore, our study provides evidence that the long-term STI consequences associated with early initiation of intercourse apply not just to females but also to males, who have been regularly excluded from previous studies. Inclusion of both current age and age at first sexual intercourse in these models controlled for the length of time a participant had been sexually active.
