This current dissertation consists of two sub-studies that aimed to expand our limited understanding about directionality and mechanisms in the longitudinal association between tobacco use and mental health, using secondary data of a nationally representative sample of adolescents and adults in the United States.

Sub-Study 2 aimed to investigate how the trajectories of smoking behaviors in developmentally important periods (i.e., adolescence and young adulthood) were associated with subsequent mental health, and to test if alcohol and marijuana use in adulthood might mediate the relationship between smoking trajectories and subsequent mental health. Data were drawn from Round 1 to Round 18 of the National Longitudinal Survey of Youth 1997. Group-based multi-trajectory modeling identified seven distinct smoking trajectories based on longitudinal change in multiple indicators of smoking behaviors over 10 years from adolescence to young adulthood. The results from the linear regression model indicated that late-onset moderate smokers, late-onset accelerated smokers, early-onset heavy smokers, and early-onset moderate smokers showed significantly poorer mental health in later adulthood than stable abstainers, even after controlling for baseline mental health condition and covariates. However, the mental health score of quitters in adulthood was not significantly different from that of stable abstainers. Moreover, the results from the joint significance test and causal mediation analysis demonstrated that the use of alcohol and marijuana in adulthood mediated the association between each smoking trajectory and poor mental health. The findings of sub-study 2 suggest that continued smoking, especially early-onset and heavy smoking, from adolescence to young adulthood may have a long-lasting negative impact on mental health, and quitting may mitigate such impact.

Aims: To measure the prospective relationship between smoking trajectories from adolescence to young adulthood and mental health in later adulthood and test whether this relationship was mediated by concurrent co-use of alcohol and marijuana.

Design: Longitudinal study using data drawn from Round 1 to Round 18 of the National Longitudinal Survey of Youth 1997 (NLSY97), a nationally representative cohort study spanning 21 years.

Measurements: Mental health in adulthood was measured using the five-item Mental Health Inventory (MHI-5; range 0-100) at Round 18. Seven trajectories of smoking from adolescence to young adulthood were identified by group-based multi-trajectory modeling, using data over 11 years from Round 1 to Round 11.

Findings: Late-onset moderate smokers..., late-onset accelerated smokers..., early-onset heavy smokers..., and early-onset moderate smokers...showed poorer regression-adjusted mean MHI-5 scores in later adulthood than stable abstainers, even after controlling for baseline mental health and covariates. Whether or not a difference in MHI-5 scores was present between quitters and stable abstainers was inconclusive. The concurrent co-use of alcohol and marijuana in young adulthood significantly mediated the relationship between smoking trajectory and mental health.
