Impact of social networks and norms on e-cigarette use among adolescents in Southern California: a prospective cohort study.

ABSTRACT:

Objective

Using social network analysis, we assessed the mechanisms of social influence that promote e-cigarette use in adolescent networks.

Methods

Data on health behaviours and friendship networks from a cohort of 10 high schools in Southern California (N=1599) were collected in grade 9 Spring 2021 (W1), grade 10 Fall 2021 (W2) and Spring 2022 (W3). Two mixed effects logistic regression models were estimated (full sample and subsample of non-vapers only) to evaluate the associations of W1 and W2 pro-vaping norms, peer e-cigarette use exposure and prior e-cigarette use (full sample) on past 6-month vaping at W3, adjusting for demographic covariates and school clustering.
