Daily variation in the patterns and characteristics of adolescent ENDS use.

Introduction:
This text provides an analysis of a study on the patterns and characteristics of adolescent electronic nicotine delivery systems (ENDS) use. The study utilizes ecological momentary assessment (EMa) to gather detailed data on the contexts in which ENDS use occurs, the frequency of use, and the time-varying contexts of adolescent ENDS use. The results of the study can inform prevention efforts and policies focused on reducing ENDS use in this vulnerable population.

Key Points:

* The study included a sample of 50 adolescents who were past two-week ENDS users.
* EMa surveys were administered over 14 consecutive days to gather data on daily ENDS and tobacco use behaviors, potential influences of same-day contexts, and characteristics of use.
* The study found that adolescent ENDS use was more frequent and adolescent cigarette use was less frequent on weekends.
* There was daily variability in the contexts and characteristics of situations where adolescents used ENDS, which were largely social-normative.
* Marijuana accompanied more than a quarter of ENDS use occasions.
* The study suggests that socio-ecological context is important in developing prevention messaging relevant to the context where adolescents use.
* The data reported in the study have not been made publicly available, and the study design, hypotheses, and analysis plan were not preregistered.

Main Message:
The study highlights the importance of understanding the patterns and characteristics of adolescent ENDS use in order to inform prevention efforts and policies. The results suggest that prevention messaging may be most relevant and effective on weekends when youth exposure to advertising and peer influences are greatest. additionally, the study emphasizes the need to consider socio-ecological context in developing prevention resources. The findings can help regulatory agencies and public health officials to develop effective strategies to reduce adolescent ENDS use.
