This study utilized data from the National Longitudinal Survey of Youth to investigate youth risk trajectories for HIV and factors associated with different trajectories. The sample ( N = 8,208) was 49.2% female, with a mean age of 14.31 ( SD = 1.48). A group-based trajectory model was applied, which identified four distinct trajectories for both males and females: (1) consistently higher sexual risk levels, increasing to early adulthood followed by some decrease ("high"); (2) a short period of increase to late teens, followed by a longer period of decrease ("decreased"); (3) an initially slow increase, with the increase accelerating by late teens, and a slight decline beginning in early adulthood ("increased"); and (4) consistently lowest levels of sexual risk ("low"). More African Americans were found among the decreased trajectory group; among the low risk group a higher number of youth came from families with parents who spoke a language other than English. The high-risk group had a higher percentage of subjects in non-metropolitan areas and highest alcohol use. Among males, being employed and being in the military were associated with inclusion in the high-risk group. Results have implications for specializing prevention strategies for youth with different patterns of sexual risk. [ABSTRACT FROM AUTHOR]

This study utilised data from the National Longitudinal Survey of Youth to investigate risk trajectories for delinquency and factors associated with different trajectories, particularly substance use. The sample (n = 8984) was 49% female. A group-based trajectory model was applied, which identified four distinct trajectories for both males and females: a High group with delinquency rates consistently higher than other groups, with some decrease across the age range; a Decreased group, beginning at high levels with substantial decrease to near zero; a Moderate group, experiencing some decline but remaining at moderate rates of delinquency through most of the age range; and a consistently Low group, having low rates of delinquency declining to near zero by mid-teens to late-teens. The Low group was distinguished by several protective factors, including higher rates of maternal authoritative parenting style, possible lower acculturation (higher rates of non-English spoken at home), higher rates of religious activity, later substance use initiation, lower rates of early delinquent activity, less early experience with neighbourhood or personal violence, and higher rates of perceiving penalty for wrongdoing. Conversely, the High group was characterised by several vulnerability factors – essentially the converse of the protective factors above.
