School Discipline and Racial Disparities in Early Adulthood

Despite interest in the contributions of school discipline to the creation of racial inequality, previous research has been unable to identify how students who receive suspensions in school differ from unsuspended classmates on key young adult outcomes. We utilize novel data to document the links between high school discipline and important young adult outcomes related to criminal justice contact, social safety net program participation, postsecondary education, and the labor market. We show that the link between school discipline and young adult outcomes tends to be stronger for Black students than for White students, and that approximately 30% of the Black–White disparities in young adult criminal justice outcomes, SNAP (Supplemental Nutrition Assistance Program) receipt, and college completion can be traced back to inequalities in exposure to school discipline.

Longitudinal Links between Income Dynamics and Young Adult Socioeconomic and Behavioral Health Outcomes

Longitudinal links between childhood family income and adult outcomes are well documented. However, research on childhood income volatility and young adult outcomes is limited. This study utilizes data from the NLSY ( N = 6,410) to examine how childhood family income and income volatility relate to socioeconomic outcomes and mental/behavioral health in emerging adulthood. Results show that lower childhood income was associated with young adult socioeconomic and behavioral health outcomes. Higher income volatility was associated with increased depression and teen parenthood during young adulthood. Additional analyses examining trajectories of income volatility illustrated that children in families with unstable income trajectories (i.e., frequent income losses and gains) showed higher depression scores than those with stable trajectories. These findings suggest that income volatility, not just income level or income loss, is important to consider when studying economic disparities in young adult outcomes. Implications for policies and programs for low-income, high-volatility households are discussed.

Young adult outcomes of childhood prophylaxis for severe hemophilia A: results of the Joint Outcome Continuation Study

The Joint Outcome Study (JOS), a randomized controlled trial, demonstrated that children with severe hemophilia A (HA) initiating prophylactic factor VIII (FVIII) prior to age 2.5 years had reduced joint damage at age 6 years compared with those treated with episodic FVIII for bleeding. The Joint Outcome Continuation Study (JOS-C) evaluated early vs delayed prophylaxis effects on long-term joint health, following JOS participants to age 18 years in an observational, partially retrospective study. Index joint magnetic resonance imaging (MRI) scores of osteochondral (OC) damage (primary outcome), joint physical examination scores, and annualized rates of joint/other bleeding episodes (secondary outcomes) were collected. Thirty-seven of 65 JOS participants enrolled in JOS-C, including 15 randomized to prophylaxis at mean age 1.3 years (“early prophylaxis”); 18 initially randomized to episodic treatment, starting “delayed prophylaxis” at mean age 7.5 years; and 4 with high-titer inhibitors. At JOS-C exit, MRI OC damage was found in 77% of those on delayed and 35% of those on early prophylaxis for an odds ratio of OC damage, in the delayed vs early prophylaxis group, of 6.3 (95% confidence interval, 1.3, 29.9; P = .02). Annualized bleeding rates were higher with delayed prophylaxis (mean plus or minus standard deviation, 10.6 ± 6.6 vs 3.5 ± 2.1; P < .001), including when only comparing time periods on prophylaxis (6.2 ± 5.3 vs 3.3 ± 1.9; P < .05). In severe HA, early initiation of prophylaxis provided continued protection against joint damage throughout childhood compared with delayed initiation, but early prophylaxis was not sufficient to fully prevent damage. This trial was registered at www.clinicaltrials.gov as #NCT01000844.

Subtypes of Girls Who Engage in Serious Delinquency and Their Young Adult Outcomes

Girls are increasingly becoming involved with the juvenile justice system; however, what brings girls to engage in delinquency or what obstacles these girls face later in life resulting from adolescent criminal behavior is understudied. In the present study, we used latent class analysis to identify subtypes of risks among adolescent girls ( N = 1,174) who have engaged in delinquent behaviors and mixture modeling to determine what distal psychological, social, educational, and economic outcomes in young adulthood are associated with each subtype. Four adolescent subtypes were identified, which were distinguished primarily based on the severity of their self-reported victimization experiences and mental health concerns. Classes with higher levels of victimization experiences tended to report more engagement with delinquent behavior in adolescence and had a larger proportion of Black and Hispanic girls than lower-victimization classes. Identified classes differed from each other on distal (i.e., young adulthood) measures of economic instability, educational attainment, drug use, depression, and adult arrests. Generally, latent classes which were characterized by higher rates of victimization and mental health concerns and lower educational performance in adolescence fared worse in young adulthood. Implications for those who care for girls who engage in delinquency, including suggestions for using trauma and culture informed screening, prevention, and intervention services, and directions for future research are discussed.
