School-Level Prevalence and Predictors of e-Cigarette Use in 8th, 10th, and 12th Grade U.S. Youth: Results From a National Survey (2015-2016).


ABSTRACT:

Purpose

The aim of this study was to examine the school-level prevalence and predictors of e-cigarette use among U.S. adolescents.

Methods

The Monitoring the Future study is an annual national cross-sectional study of secondary (middle and high) school students. This study uses 2015 and 2016 survey data from 8th, 10th, and 12th grade students (n = 38,926) attending 580 U.S. public and private secondary schools. E-cigarette use, binge drinking, cigarette smoking, marijuana use, and nonmedical prescription drug use were measured at the individual level. School-level characteristics were measured with both aggregated student-level measures (e.g., school-level e-cigarette use, school-level racial composition) and school characteristics (e.g., public vs. private, urban vs. rural).

Results

The prevalence of past-month e-cigarette use varied considerably across 580 U.S. middle and high schools, ranging from 0% to 60% at individual schools (mean = 10.2%, standard deviation = 8.9%). Multivariable regression analyses indicated that past-month e-cigarette use was significantly higher at schools with a higher proportion of White students, schools that were located in the U.S. Southern and Western regions, and schools with higher prevalence of past-month cigarette smoking, after controlling for relevant individual- and school-level covariates.

Conclusions

E-cigarette use varies considerably across schools, and this study suggests that school context plays an important role in e-cigarette use. Cigarette smoking and e-cigarette use at the school level are closely linked and are important risk factors for individual-level e-cigarette use. The wide variation in prevalence of e-cigarette use highlights the need for schools to work with professionals to obtain school-level assessment rather than relying solely on state or national results to guide prevention efforts.
