Rural disparities in adolescent smoking prevalence.

Introduction Rural residence is a well-established risk factor for risk behaviors and subsequent morbidity and mortality in the United States. Smoking is the primary cause of preventable death and is more prevalent in rural America. As chronic smoking habits typically develop during adolescence, the discrepancy in smoking rates between rural and urban youth likely contributes to a significant geographic disparity in the long-term health of adults. Methods Data were extracted from 12th-grader surveys of the US Monitoring the Future study from 1998 to 2018. The historic trends of smoking initiation, ever-regular and current-regular smoking rates of rural and urban adolescents were estimated with intercept-only time-varying effect models. Differences in prevalence between rural and urban youth were calculated for each smoking behavior. Results Though overall smoking prevalence continues to decline, this trend is significantly attenuated among rural adolescents compared to urban youth. The absolute difference in lifetime smoking prevalence between rural and urban youth has markedly increased from 6.9% in 1998 to 13.5% in 2018, which is among the highest in the past 20 years and is a potentially alarming upward trend. However, the absolute differences in ever-regular and current-regular smoking prevalence have shown an overall net decline, decreasing from 6.4 to 4.8%, and from 5.5 to 3.0%, respectively. Conclusions This geographic disparity between rural and urban adolescents represents a potentially modifiable cause of increased morbidity and mortality in rural areas. Interventions and regulatory efforts should be tailored for rural adolescents to reduce the narrowing but persistent disparity in regular smoking.
