Cigarette-smoking trajectories were assessed among monorace Blacks, Black–American Indians, Black–Asians, Black–Hispanics, and Black–Whites. We used a subsample of nationally representative data obtained from the National Longitudinal Study of Adolescent Health (Add Health). The sample consisted of adolescents who were in Grades 7 to 12 in 1994, and followed across four waves of data collection into adulthood. Wave 4 data were collected in 2007-2008 when most respondents were between 24 and 32 years old. Respondents could report more than one race/ethnicity. Poisson’s regression was used to analyze the data. We found distinct smoking trajectories among monorace and biracial/ethnic Blacks, with all groups eventually equaling or surpassing trajectories of Whites. The age of cross-over varied by gender for some subgroups, with Black–American Indian males catching up earlier than Black–American Indian females. Black–White females smoked on more days than monorace Black females until age 26 and also smoked more than Black–White males between ages 11 and 29 years. Black–Hispanic males smoked on more days than Black–Hispanic females from ages 11 to 14. The results of the interaction tests also indicated different smoking trajectories across socioeconomic status (SES) levels among White, Black, and Black–White respondents. Significant heterogeneity was observed regarding smoking trajectories between monorace and biracial/ethnic Blacks. Knowledge of cigarette-smoking patterns among monorace and biracial/ethnic Black youth and young adults extends our understanding of the etiology of tobacco use and may inform interventions.
