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.

Growing up in rural North Carolina, Trenette Clark watched as some loved ones went to jail at young ages and others lost their children to the Child Welfare System.

She came to wonder why some drug users’ behavior spirals into a vortex of addiction and why those exposed to the same drug can have very different experiences from one another. She also wondered why so much research was restricted to one race.

After receiving a $829,000 grant from the National Institutes of Health, Clark, a UNC professor of social work, hopes to answer these questions and many more, specifically questions surrounding the practically untouched topic of biracial adolescents…

Highlights

  • We found an intermediate biracial phenomenon.
  • White-American Indian youth start smoking cigarettes earlier than all groups.
  • White-Asian youth begin smoking marijuana and drinking at earlier ages than Whites.
  • White-Asian youth engaged in all substances at earlier ages than Asian youth.

This study examines age of first cigarette, alcohol, and marijuana use among self-identified biracial youth, using data from the National Longitudinal Study of Adolescent Health (Add Health). We found an intermediate biracial phenomenon in which some biracial youth initiate substance use at ages that fall between the initiation ages of their 2 corresponding monoracial groups. When controlling for the covariates, our findings show White-Asian biracial youth begin smoking marijuana and drinking alcohol at earlier ages than Whites and engaging in all forms of substance use at earlier ages than Asian youth. Results indicate White-American Indian youth start smoking cigarettes at earlier ages than all biracial and monoracial groups. Our findings underscore the need for future research to examine substance-use initiation and progression among biracial/ethnic youth.
