Relationship characteristics and contraceptive use among dating and cohabiting young adult couples.

CONTEXT: Contraceptive decision making occurs in the context of relationships. Although many individual-level characteristics have been linked to youths' contraceptive use, less is known about associations between contraceptive use and relationship-level characteristics. METHODS: Data from the 2001-2002 romantic pair subsample of the National Longitudinal Study of Adolescent Health were used to describe characteristics of 322 dating relationships and 406 cohabiting relationships among young adults aged at least 18 years. Logistic regression was employed to assess associations between these characteristics and hormonal or long-acting contraceptive use and condom use. Data from both partners allowed discordance in reports between partners in some measures to be examined. RESULTS: Cohabiting couples were less likely than dating couples to have used condoms (19% vs. 37%) and hormonal or long-acting methods (40% vs. 57%) at last sex. In dating relationships, couples reporting discordant levels of intimacy and couples in which neither partner reported a high level of intimacy had greater odds of condom use than couples in which both partners reported high intimacy (odds ratios, 4.5 and 3.3, respectively); mistrust and male problem drinking were negatively associated with condom use (0.3 for each). For cohabiting couples, frequency of sex was negatively associated with condom use and hormonal method use (0.8 for each). CONCLUSIONS: At least for dating couples, contraceptive use is linked to multiple dimensions of relationships, particularly measures reflecting relationship quality-both positive and negative.

Racial and ethnic differences in the transition to a teenage birth in the United States.

CONTEXT: Rates of teenage childbearing are high in the United States, and they differ substantially by race and ethnicity and nativity status. METHODS: Data from the National Longitudinal Survey of Youth 1997 cohort were used to link characteristics of white, black, U.S.-born Hispanic and foreign-born Hispanic adolescents to teenage childbearing. Following a sample of 3,294 females aged 12-16 through age 19, discrete-time logistic regression analyses were used to examine which domains of teenagers' lives were associated with the transition to a teenage birth for each racial and ethnic group, and whether these associations help explain racial and ethnic and nativity differences in this transition. RESULTS: In a baseline multivariate analysis controlling for age, compared with whites, foreign-born Hispanics had more than three times the odds of a teenage birth (odds ratio, 3.5), while blacks and native-born Hispanics had about twice the odds (2.1 and 1.9, respectively). Additional controls (for family environments; individual, peer and dating characteristics; characteristics of first sexual relationships; and subsequent sexual experience) reduced the difference between blacks and whites, and between foreign-born Hispanics and whites, and eliminated the difference between U.S.-born Hispanics and whites. Further, if racial or ethnic minority adolescents had the same distribution as did white teenagers across all characteristics, the predicted probability of a teenage birth would be reduced by 40% for blacks and 35% for U.S.-born Hispanics. CONCLUSIONS: Differences in the context of adolescence may account for a substantial portion of racial, ethnic and nativity differences in teenage childbearing.

Coparenting and children's school readiness: a mediational model.

We examined the long-term direct and indirect links between coparenting (conflict, communication, and shared decision-making) and preschoolers' school readiness (math, literacy, and social skills). The study sample consisted of 5,650 children and their biological mothers and fathers who participated in the Early Childhood Longitudinal Study-Birth Cohort. Using structural equation modeling and controlling for background characteristics, we found that our conceptual model of the pathways from coparenting to child outcomes is structurally the same for cohabiting and married families. Controlling for a host of background characteristics, we found that coparenting conflict and shared decision-making were negatively and positively, respectively, linked to children's academic and social skills and co-parental communication was indirectly linked to academic and social skills through maternal supportiveness. Coparenting conflict was also indirectly linked to children's social skills through maternal depressive symptoms. The overall findings suggest that for both cohabiting and married families, the context of conflicted coparenting may interfere with the development of children's social competencies and academic skills, whereas collaborative coparenting promotes children's school readiness because mothers are more responsive to their children's needs. These findings have implications for programs aimed at promoting positive family processes in cohabiting and married families.

Risky adolescent sexual behaviors and reproductive health in young adulthood.

CONTEXT: Little research links adolescent risk behaviors to reproductive health outcomes beyond adolescence, although young adults--men and women in their early 20s--bear a disproportionate burden of STDs and unintended childbearing. METHODS: To assess whether individuals who engaged in risk behaviors during adolescence had increased risk of negative reproductive health outcomes in young adulthood, data from Waves 1-4 of the National Longitudinal Study of Adolescent Health on 5,798 sexually active respondents were analyzed. Logistic and multinomial logistic regressions examined associations between risk behaviors (cumulatively and individually) and each of three outcomes. RESULTS: Four in 10 youth reported at least three risk factors during adolescence. Women who were exposed to an increasing number of risks had an elevated likelihood of having had multiple sex partners in the last year, rather than none (relative risk ratio, 1.3); having had an STD (odds ratio, 1.1); and having had an intended or unintended birth, as opposed to no birth (relative risk ratio, 1.1 for each). Inconsistent contraceptive use and having had multiple partners, a non-monogamous partner or a non-romantic partner were associated with reporting multiple partners in the last year; inconsistent use, sexual debut after age 16 and not discussing contraception with a partner were associated with having any birth. CONCLUSIONS: Teenagers' sexual behaviors have both short-term and long-term consequences, and interventions that focus on multiple domains of risk may be the most effective in helping to promote broad reproductive health among young adults.
