The Relative Importance of Immigrant Generation for Mexican Americans’ Alcohol and Tobacco Use from Adolescence to Early Adulthood

The rapidly growing Hispanic population in the US may be at-risk for greater substance use according to immigrant generation
status. This study utilized latent growth curve analyses to determine whether trajectories of alcohol and cigarette use vary
according to immigrant status in a Mexican-heritage sample (n = 1,274) from the National Longitudinal Study of Adolescent
Health. Changes in alcohol and cigarette use were estimated over a 13-year span from adolescence (mean age = 15.9) to early
adulthood. Alcohol use did not vary significantly by immigrant status. In contrast, third generation youth experienced greater
increases in cigarette use over time compared to their second generation peers. Second generation youth also experienced greater
acceleration in cigarette use compared to first generation youth. Immigrants who arrived in the US more recently experienced
slower acceleration in cigarette use compared to those who have been in the US for longer periods of time.
