Key Points Question What are the prevalence, patterns, and correlates of use and polyuse of combustible, edible, and vaporized cannabis products among adolescents? Findings In a 2015 cross-sectional survey study of 3177 adolescents, ever use of edible (21.3%) or vaporized (10.5%) cannabis was appreciable, and most ever users of cannabis (61.7%) used at least 2 products. Current use was higher in boys than girls for vaporized (6.1% vs 3.0%) but not for combustible (13.8% vs 13.1%) or edible (8.4% vs 7.3%) cannabis. Meaning Health professionals should be aware that youth might use a diverse spectrum of combustible and alternative cannabis products.

This study examined pathways through which family socioeconomic status may influence adolescents’ academic achievement. We focused on parental monitoring and adolescents’ after-school time-use patterns as linking mechanisms. Participants were 441 twelve- to fourteen-year-old Korean adolescents who participated in the Korea Welfare Panel Study. Higher family economic pressure was linked with lower parental monitoring through elevated levels of parental depression. Parental monitoring was associated with more time spent in structured learning-oriented activities and less time spent in unstructured nonacademic activities. Both types of time-use activities and parental monitoring were associated with academic achievement. The results supported both the family stress model and the family investment model, indicating that families’ socioeconomic conditions were directly and indirectly linked to adolescents’ academic achievement. The findings are discussed in the context of Korean culture, which emphasizes high parental involvement and economic investment in children’s education. We also present broader implications beyond the local context.

The present study investigated the mediating effects of adolescent BMI trajectories on socioeconomic continuity over the early life course using a nationally representative sample of 11,075 respondents. This study considered both the initial severity as well as change over time in BMI as psycho‐physiological mediators. Consistent with the life course pathway model and the cumulative advantage and disadvantage principle, the results suggested that early socioeconomic adversity is associated with youth BMI trajectories over time, which in turn, impair young adult socioeconomic attainment. The results also revealed important gender and racial/ethnic differences in the hypothesized associations. These findings elucidate how early adversity exerts an enduring long‐term influence on social attainment in young adulthood. Further, the findings suggest that effective obesity intervention and prevention programs should focus not only on the severity of obesity but also on growth in BMI over the early years.

Objectives The current study, using prospective data over 25 years (1991–2015), concurrently investigates patterns of body mass index (BMI) and affective symptom trajectories in middle-aged mothers and the socioeconomic antecedents and disease outcomes of these patterns. Method Growth mixture modeling was used to identify latent classes of conjoint health risk trajectories (BMI, depressive symptoms, and anxiety symptoms) from 1991 to 2001. For each latent class, we identified mean trajectories of each health risk. Then, analyses were conducted identifying how these conjoint health risk classes were associated with respondents’ socioeconomic background profiles in 1991 and subsequent chronic health problems in 2015. Results Socioeconomic background profiles were significantly associated with initially high-risk trajectories. There was a statistically significant association between membership in certain classes of conjoint trajectories and physical health outcomes in later years. Consistent patterns of association with changes in different health outcomes including onset of diseases were observed when classes of conjoint risk trajectories are examined. Discussion The identification of members of various conjoint risk trajectory groups provides a potentially useful prognostic tool for early preventive intervention efforts, treatment, and policy formation. Such interventions should promote and develop resiliency factors, thereby aiding in the redirection of middle-aged women’s adverse risk trajectories.
