Cumulative Psychosocial and Health Disparities in US Adolescent Cigarette Smoking, 2002 to 2019.

Background: Understanding disparities in adolescent cigarette smoking is important for effective prevention.

Methods: We investigated disparities in adolescent smoking based on cumulative reported psychosocial/health risk among respondents ages 12-17 years in the US National Survey of Drug Use and Health from 2002 to 2019. Multivariable regression estimated associations of cumulative risk, survey years, and their interaction predicting past-month and daily smoking.
