Consistent use of hormonal contraceptive methods can help reduce high rates of unintended pregnancy among teens and young adults in the U.S. We use 10 years of data from the National Longitudinal Survey of Youth, 1997 cohort, to example transitions onto and off of hormonal methods among teens and young adults. Preliminary analyses find that 76% of our sample used hormonal methods at some point, but 56% of these women subsequently switched to a less effective method or no method. Preliminary discrete-time event history analyses indicate that greater educational engagement and performance are associated with greater odds of transitioning onto and staying on hormonal methods, while race/ethnic minorities have lower odds. Having multiple sexual partners, a casual relationship or a partner of a different race/ethnicity are associated with reduced odds of hormonal method use. We will run Latent Class Growth Models to better understand patterns of method use over time.

Relationship Characteristics and Contraceptive Use Among Young Adults

Young adults have high rates of unintended childbearing and STDs, yet little research has examined the role of relationship characteristics in their contraceptive use.

METHODS:
Data collected from the 2002-2005 rounds of the National Longitudinal Survey of Youth yielded a sample of 4,014 dating relationships among sexually active 18-26-year-olds. Bivariate analysis and multivariate logistic and multinomial logistic regressions assessed associations between relationship characteristics and contraceptive use at last sex.

RESULTS:
In three-quarters of the relationships, respondents had used some method at last intercourse; respondents in 26% of the relationships had used a condom only, in 26% a hormonal method only and in 23% dual methods. Compared with respondents in relationships in which first sex occurred within two months of starting to date, those who first had sex before dating were more likely to have used any method at last sex (odds ratio, 1.4), particularly condoms or dual methods (relative risk ratio, 1.5 for each). The relative risk of using a hormonal method only, rather than no method or condoms only, increased with relationship duration (1.01) and level of intimacy (1.1-1.2). Discussing marriage or cohabitation was associated with reduced odds of having used any method (0.7) and a reduced relative risk of having used condoms alone or dual methods (0.6 for each). Increasing levels of partner conflict and asymmetry were also linked to reduced odds of any method use (0.97 and 0.90, respectively).

CONCLUSIONS:
Prevention programs should address relationship context in contraceptive decision making, perhaps by combining relationship and sex education curricula to foster communication and negotiation skills.

Data from the 2002–2005 rounds of the National Longitudinal Survey of Youth 1997 cohort were used to examine contraceptive use in 3,485 young adult dating relationships. Latent class analysis was employed to develop a typology of relationships using measures of relationship structure (duration) and quality (intimacy, commitment and conflict). Multinomial logistic regression analyses were used to estimate associations between relationship type and contraceptive use and method choice at last sex.

Relationship Characteristics and the Relationship Context of Nonmarital First Births Among Young Adult Women

Objectives: The objectives of this study were to examine whether and how characteristics of the relationship dyad are linked to nonmarital childbearing among young adult women, additionally distinguishing between cohabiting and nonunion births.

Methods: We used the National Longitudinal Survey of Youth, 1997 Cohort and discrete time-event history methods to examine these objectives.

Results: Our analyses found that similarities and differences between women and their most recent sexual partner in educational attainment, disengagement from work or school, race/ethnicity, and age were linked to the risk and context of nonmarital childbearing. For example, partner disengagement (from school and work) was associated with increased odds of a nonmarital birth regardless of whether the woman herself was disengaged. Additionally, having a partner of a different race/ethnicity was associated with nonmarital childbearing for whites, but not for blacks and Hispanics.

Conclusions: We conclude that relationship characteristics are an important dimension of the lives of young adults that influence their odds of having a birth outside of marriage.
